Fears are growing that the confrontation could spread from the Strait of Hormuz to the Red Sea after Iran reportedly urged its Houthi allies in Yemen to prepare to block the Bab el-Mandeb.

Iran has instructed its Houthi allies in Yemen to prepare to disrupt oil tanker traffic through the Red Sea if the United States targets Iran’s power grid or energy infrastructure, raising fresh concerns over the security of one of the world’s most vital maritime chokepoints.
Should the Houthis act on Tehran’s request, the confrontation that has already threatened shipping in the Strait of Hormuz could expand to the Bab el-Mandeb, a strategic gateway linking the Red Sea with the Gulf of Aden and carrying a significant share of global trade between Asia and Europe.
The Houthis have previously carried out dozens of attacks on commercial vessels in the Red Sea and the Bab el-Mandeb, saying the campaign was intended to pressure Israel and its allies to end the war in Gaza. Those attacks forced many shipping companies to reroute vessels away from the Red Sea and prompted the United States and several European countries to deploy naval forces to protect maritime traffic.
Still, analysts question whether the Houthis have the capability to shut down the Bab el-Mandeb entirely, even if they remain capable of carrying out intermittent attacks and increasing the risks for commercial shipping.
“The group can launch attacks or raise the cost of transit through the strait, but closing it would require military, logistical and maritime control capabilities that it simply does not possess,” Ibrahim Al-Malek, a writer and researcher specializing in strategic governance, told MBN.
The Bab el-Mandeb is one of the world’s most important oil transit routes. According to the Council on Foreign Relations, roughly 12 to 15 percent of global seaborne trade passes through the strait each year.
Perim Island divides the waterway into two channels, with international shipping primarily using the western channel, which is about 16 miles (26 kilometers) wide near Djibouti. Despite its relatively narrow width, securing the passage requires sustained military deployments and continuous surveillance.
In December 2023, the United States launched Operation Prosperity Guardian, a multinational effort involving Arab and European partners to safeguard commercial shipping in the Red Sea, the Gulf of Aden and the Bab el-Mandeb.
Washington followed that effort in March 2025 with Operation Rough Rider, targeting Houthi missile capabilities, drones and infrastructure that U.S. officials said was being used to attack commercial vessels.
By late April of that year, U.S. Central Command said it had struck more than 800 targets, killing hundreds of militants and several senior Houthi leaders.
Meanwhile, the European Union’s Operation Aspides continues to patrol the Red Sea and Gulf of Aden amid concerns that the Houthis could resume attacks on international shipping.
The risks carry particular significance for Saudi Arabia, which has increasingly relied on its Red Sea export terminal at Yanbu as disruptions in the Strait of Hormuz have intensified.
Reuters reported Sunday that the kingdom routed about 75 percent of its oil exports through Yanbu in July in an effort to reduce its dependence on Gulf export routes.
The shift has coincided with renewed tensions between the Houthis and Saudi Arabia. The group’s leader has threatened to target Saudi airports, ports and oil facilities but has not announced any operation aimed at closing the Bab el-Mandeb.
According to data cited by Reuters from the maritime analytics platform Signal Ocean, Saudi crude shipments from Yanbu reached 4.7 million barrels per day by July 13, up from 3.36 million barrels per day on July 10.
Average loading volumes have exceeded 4 million barrels per day since June, compared with roughly 973,000 barrels per day during the same period in 2025, underscoring Saudi Arabia’s growing reliance on Red Sea export routes to offset reduced shipments through the Strait of Hormuz.
Retired Air Force Maj. Gen. Abdullah Ghanem Al-Qahtani told MBN that while the Houthis can threaten maritime traffic, they currently lack the capability to close the strait altogether.
“Threatening navigation is possible, but today’s Houthi movement no longer possesses the capabilities it had several years ago,” he said.
Although Houthi attacks on commercial shipping have declined following the U.S. military campaign and the end of the Gaza war, analysts say the group’s ability to disrupt traffic through the Bab el-Mandeb will ultimately depend on the missile and drone capabilities it still retains, as well as the scale of any military response to an attempt to block the strategic waterway.

Chongqing - As scorching summer temperatures bake southwestern China, construction crews on three major Chongqing railway projects are being shielded from extreme heat through mist-spraying systems, staggered shifts and concrete-cooling plants.
At the redevelopment site of Chongqing Railway Station, two 10-meter-high automated spray towers rotate 360 degrees, covering a 30-meter radius with fine mist. A tower crane adds another cooling layer, backed by 100 fixed sprinklers.
Fog cannons and water trucks patrolling every two hours have reduced perceived temperatures by 5 to 10 degrees, said Wang Ganglong, deputy production manager at China Railway 11th Bureau.
"It keeps the air moist and takes the scorch off the ground," said welder Liu Gangan. The station, known locally as Caiyuanba, is being overhauled with over 200 workers on site.
At the 404-meter Lisicun Bridge in Fuling District, part of the Yichang-Fuling high-speed railway, crews use three air-conditioned rest stops offering mung bean soup and iced drinks.
Rebar worker Li Baoguo reported that his team completes nearly 400 steel bar bindings daily. "The bars get hot enough to fry an egg," he joked. After finishing a round, he headed to a stop, downed a bowl of soup, and sighed with relief. "Free soup and medicine give us peace of mind."
To shield workers from peak heat, the project has rolled out a staggered shift schedule, with crews starting at 6 a.m., knocking off by 10 a.m., and resuming at 4 p.m.
Beyond the shelters and adjusted hours, the site has layered on additional safeguards. Party representatives conduct daily wellness checks, while volunteer teams deliver cooling supplies to elevated platforms and tunnel faces, accompanied by on-the-spot safety briefings.
Inside the 14.78-km Tiefengshan tunnel, part of the Xi'an-Chongqing high-speed railway, concrete quality is critical as the final push nears. "High temperatures are concrete's worst enemy," said site manager Xia Wujun. "Even slight deviations can cause temperature cracks and compromise structural safety."
At the Wanzhou batching plant, an intelligent system uses air blowers, water chillers, and ice makers to produce over 10 tons of ice daily. The system pre-cools aggregates in an enclosed chamber and chills mixing water. Sensors feed data to a central unit that automatically adjusts the output.
Concrete discharge temperatures remain below 30°C—a 10-degree reduction that eliminates the risk of cracking, according to Xia.
The S&P 500 (^GSPC 1.01%), Nasdaq Composite (^IXIC 1.40%), and Dow Jones Industrial Average (^DJI 0.77%) have been breaking record after record over the past year, but there's at least one investor who is being cautious right now.
Warren Buffett expressed concern over the stock market in a recent interview with CNBC during Berkshire Hathaway's annual meeting, even going so far as to say that some investors are "gambling" right now.
While even renowned investors like Buffett can't predict the future, decades worth of history suggest that he's spot-on. Here's his best advice for what investors should do right now.

Many investors are taking unnecessary risks
During the interview, Buffett reiterated his idea that the stock market is like a church with a casino attached -- one representing slow-and-steady growth and the other, short-term risk-taking. "The casino has gotten very attractive to people," he noted, adding, "that's not investing, it's not speculating, it's gambling."
This advice is perhaps more important than ever, as the artificial intelligence (AI) boom has led to soaring company valuations. Many investors are eager to buy into the new wave of tech, and while some stocks can lead to life-changing wealth, not all companies will thrive over time.
We don't need to look too far into the past to see the potential consequences, either. In the late 1990s, hundreds of internet companies raised staggering amounts of capital during their initial public offerings (IPOs). When the bubble popped, however, many of them quickly burned through cash and couldn't survive the following bear market.

During the dot-com bear market, the Nasdaq lost nearly 80% of its value, and many individual companies fared even worse. To be clear, this doesn't necessarily mean that we're in an AI bubble that will mirror the dot-com bubble. But it's easy for many investors to get caught up in surging stock prices and buy into companies with less-than-healthy fundamentals.
The best move investors can make right now
During the interview, Buffett also noted that, despite many investors taking on more risk than necessary, "that doesn't mean that investing is terrible. It does mean that prices for an awful lot of things will look very silly."
With enough hype, even the weakest companies can thrive in the near term. But if a stock is overvalued -- meaning its stock price no longer aligns with its underlying fundamentals -- it's more likely to crash harder during the next bear market or recession.
When the market is booming, it's tempting to invest in popular stocks to ride the wave of growth. The best investments, however, aren't always the flashy ones. By investing in quality companies with strong business fundamentals, your portfolio is far more likely to thrive over time.

Outgoing defence minister Mykhailo Fedorov slammed military chief Oleksandr Syrskyi, saying he had ‘split the country’.

By Caolán Magee and Reuters
Published On 16 Jul 202616 Jul 2026
Rare protests have broken out in the Ukrainian capital against the dismissal of the country’s defence minister, part of a broader cabinet reshuffle initiated by President Volodymyr Zelenskyy that has exposed rifts in Ukraine’s military establishment.
Hundreds demonstrated near the Ivan Franko National Theatre in central Kyiv on Thursday against the move to replace Defence Minister Mykhailo Fedorov, who was credited with boosting Ukraine’s drone warfare during his short six-month tenure.
Protesters also rallied in several other cities, including Lviv, Odesa and Dnipro, while in Kyiv, they chanted “Shame!” and carried placards reading “The Russians are celebrating”.
Writing on X, Fedorov said it had been “a great honour to serve the Ukrainian people” as defence minister, before outlining what he described as the ministry’s key achievements during his tenure. They included disabling “Starlink access for Russian forces” and launching programmes to expand Ukraine’s domestic drone production during the ongoing war with Russia.
In comments to reporters, Fedorov criticised military chief Oleksandr Syrskyi, with whom he’s been in dispute with, and questioned whether Ukraine could defeat Russia with him in charge of the army.
“Instead of figuring out how to defeat Russia asymmetrically – which is the commander-in-chief’s task – he figured out how to split the country,” said Fedorov, according to AFP.
Fedorov criticised slow bureaucracy and a lack of flexibility, saying “in this configuration, I personally don’t know how to win the war”.
He also alleged that Syrskyi engineered his removal through an ultimatum issued to Zelenskyy after months of clashes.
A 35-year-old technology specialist, Fedorov was previously Ukraine’s first minister for digital transformation. He is recognised for having streamlined bureaucracy and introduced a more data-driven approach to the war against Russia.
Supporters say Fedorov’s efforts to reform defence procurement and tackle corruption made enemies within parts of the political and military establishment. Critics say he failed to deliver quickly enough on promises to overhaul military recruitment.
Zelenskyy on Thursday issued a plea for “unity” within the military’s ranks. He then appointed Yevgeniy Khmara – head of Ukraine’s SBU security service – as acting defence minister.
“Khmara has gained extensive and, in many respects, unprecedented experience with technological combat operations,” Zelenskyy said in a Facebook post.
Ukraine’s parliament approved Zelenskyy’s new wartime government on Thursday, confirming Naftogaz chief Sergiy Koretsky as the new prime minister, replacing Yulia Svyrydenko.
Koretsky headed Naftogaz, Ukraine’s state-owned energy company, throughout last winter, when repeated Russian drone and missile attacks on energy infrastructure triggered widespread power cuts and heating outages during freezing temperatures.
Before joining Naftogaz, Koretsky built his career in Ukraine’s private fuel industry, leading the WOG petrol station network and founding the Idealist Coffee Co chain. He headed the state-owned energy firms, Ukrnafta and Ukrtatnafta, between 2022 and 2025 before taking charge of Naftogaz.
Writing on X after his appointment, Koretsky said his “foremost task is to fully equip” Ukraine’s defence forces and “accelerate the expansion” of its defence industrial base.
“We will continue to give special attention to frontline communities that endure Russian attacks every day,” he said, adding that Ukraine’s strategic goal of European Union membership “remains unchanged”.
Parliament also voted to appoint deputy economy minister Taras Vysotskyi as new agriculture minister and Vsevolod Chentsov as Deputy Prime Minister for European integration, while Serhii Marchenko retained his post as finance minister.

China and Russia are not formal allies, but their ties have grown significantly closer in recent years. The two countries have been “ comprehensive strategic partners of coordination for a new era” since 2019, often sharing the goal of countering Western dominance in the international arena. But which nation holds the upper hand in this relationship?
Kremlin spokesman Dmitry Peskov, commenting on an article in The Wall Street Journal on relations between Moscow and Beijing, said on July 14 that the Russian-Chinese partnership is “based on the principle of equality”. However, if China is Russia’s largest trading partner while Russia accounts for only about 4 per cent of China’s foreign trade, can the relationship really be considered equal?
Before the Ukraine crisis erupted in 2014 , the European Union, rather than China, was Russia’s most significant economic partner. In 2013, EU member states accounted for roughly 57 per cent of Russian exports and 46.5 per cent of its imports. At the time, Russia was a major supplier of natural gas to Europe, particularly Germany. Thanks to the Nord Stream pipelines , Berlin received relatively cheap energy from Russia, which helped fuel Germany’s economic growth.
Aware that the Kremlin was unlikely to resume business as usual with Europe, Russian strategic planners sought alternative markets for the country’s gas exports. China appeared to be the best option.

Crude oil prices continued rising on Hyperliquid as investors reacted to the ongoing escalation between the US and Iran. Brent jumped to $88.7, with its 24-hour volume soaring to $59 million. West Texas Intermediate (WTI), the US benchmark, rose to $83.62, with the volume rising to $111.2 million.
Crude oil prices jump on US-Iran war escalation
Brent and WTI prices continued their recovery this weekend as the were sailing through the Strait in the last 24 hours, with 444 of them waiting.
The worst part about all this is that there is no easy way out for the current phase of the war since the memorandum of understanding (MoU) signed three weeks ago has failed.
Iran will not have an incentive to restart talks with the US as the country has attacked it at least three times during negotiations. It did that in June last year, February, and now during the MoU.
Iran will also have the incentive to prolong the war, and possibly close the Red Sea, a move that will dramatically reduce the amount of oil coming to the market. It has also warned that it will target Fujairah, another location where oil is still flowing to the market.

The four-hour chart shows that Brent crude oil price jumped to its highest level since June 12. It has soared by over 25% from its lowest level in June.
Most notably, it has moved above the bullish pennant pattern, which is made up of a vertical line and a symmetrical triangle. It also moved above the key resistance at $83.25, its highest point on June 17.
Oil has also formed a cup-and-handle pattern and moved above the 50-day Exponential Moving Average (EMA). Therefore, the price will likely continue soaring, potentially to the key resistance level of $100.

Early warnings surrounding the Strait of Hormuz suggested that European airports and fuel markets could face physical shortages by the beginning of summer. Those shortages largely failed to materialise, revealing both the adaptability of global energy markets and their persistent tendency to price worst-case scenarios long before they occur.
When the Strait of Hormuz was effectively closed at the end of February, the first forecasts were dramatic. The disruption affected a route that had carried nearly 20 million barrels per day of crude oil and petroleum products before the conflict, while Gulf exporters had also supplied a significant share of the world’s diesel, jet fuel and liquefied petroleum gas. Europe appeared particularly exposed because it imported far more aviation fuel than it produced and had relied heavily on supplies originating in the Middle East.
By April, warnings of physical shortages were becoming increasingly specific. The International Energy Agency estimated that Europe could begin running short of aviation fuel in June if it managed to replace only half of the supplies normally imported from the Gulf. Airlines warned that flights might have to be cancelled, airports considered contingency measures, and European officials began discussing the coordinated release and redistribution of jet fuel reserves. Ryanair suggested that a loss of 10% to 20% of available supply could force airlines to cut capacity during the summer season.
June has now passed, however, and European aviation has not ground to a halt. Petrol stations have not broadly run dry, diesel rationing has not been introduced and the widespread physical shortages that dominated the early discussion have not occurred. Prices increased sharply, inventories declined and individual routes became less economical, but the energy system absorbed a disruption that the IEA described as the largest in the history of the global oil market.
That outcome deserves more attention because it reveals something important about how energy crises are discussed. Markets are exceptionally good at identifying vulnerability, but they often treat exposure as though it were the same thing as inevitable collapse.
A Severe Disruption That Did Not Produce the Expected Shortage
The scale of the Hormuz shock should not be understated. At its worst, around 14 million barrels per day of oil supply were disrupted, equivalent to approximately 14% of global demand. Middle Eastern exports of refined products largely disappeared, several refineries and gas-processing facilities were shut down, and producers curtailed output because they could no longer export it or had nowhere to store it.
Jet fuel appeared to be one of Europe’s weakest points. The continent consumes roughly 1.6 million barrels per day of jet fuel and kerosene but produces closer to 1.1 million barrels per day, leaving a substantial structural import requirement. Before the conflict, most of those imports came from the Middle East. By April, shipments loaded in the region had essentially stopped, while stocks in major trading hubs were falling towards historically low levels.
On paper, the conclusion seemed unavoidable. Existing inventories would be drawn down, replacement cargoes would be insufficient, and physical shortages would emerge around June.
Yet energy balances are not static. The assumption that a missing barrel remains permanently missing overlooks the most powerful characteristic of internationally traded commodity markets: when scarcity raises prices, producers, refiners, traders and consumers all begin changing their behaviour.
Europe did not avoid shortages because the disruption proved less serious than expected. It avoided them because the rest of the system responded more aggressively than many of the early forecasts assumed.
The Supply System Moved Faster Than Expected
The most visible response came from emergency reserves. In March, the 32 members of the International Energy Agency agreed to make 400 million barrels of emergency oil stocks available—the largest coordinated release in the organisation’s history. This did not replace every lost barrel from the Gulf, but it created time for commercial supply chains to adjust and reassured refiners that additional feedstock would remain available.
Refineries then changed what they produced. European plants increased the share of each barrel converted into aviation fuel, pushing regional jet fuel yields to record levels. American refiners made a similar adjustment, with US jet fuel production exceeding two million barrels per day on a four-week-average basis for the first time. US exports subsequently reached record highs as European and Asian prices attracted supply across the Atlantic.
Alternative producers also redirected cargoes towards the highest-paying markets. Europe imported additional fuel from the United States, Canada, Nigeria, India and South Korea. Saudi Arabia increased shipments from its Red Sea port of Yanbu, allowing fuel to bypass Hormuz altogether. By early June, Saudi jet fuel flows to Europe through the Red Sea were reportedly higher than before the strait had closed.
These adjustments were neither free nor efficient. Cargoes travelled farther, refiners sacrificed the production of other fuels, traders paid higher freight costs, and airlines faced substantially more expensive contracts. Nevertheless, the physical product arrived.
The initial forecast had effectively treated Europe’s dependence on Middle Eastern aviation fuel as a fixed relationship. In reality, it was an economic relationship that could be reorganised once the price became high enough.
Demand Also Adjusted
Supply received most of the attention, but changes in demand mattered as well. Higher fuel costs made some airline routes uneconomic, leading carriers to reduce marginal services. Flights through and around the Middle East were cancelled or rerouted, lowering fuel consumption in precisely the regions experiencing the most severe disruption.
The reduction was not large enough to eliminate the supply gap by itself, but commodity markets do not require one dramatic intervention. They rebalance through hundreds of smaller changes: one refinery raises its jet fuel yield, another delays maintenance, an airline cancels an unprofitable route, a trader redirects a tanker, and a government releases stocks.
The process is messy and expensive, but collectively these adjustments transform an apparent physical shortage into a price shock.
This distinction is often lost during the first phase of an energy crisis. Analysts calculate existing inventories, subtract expected demand and identify the date at which storage should reach a critical level. The resulting deadline attracts headlines because it creates the impression of a countdown.
What such calculations cannot fully capture is how quickly the underlying variables change once the countdown becomes visible.
Energy Markets Price Fear Before They Price Adaptation
The tendency to exaggerate imminent scarcity is partly built into the structure of energy trading. Markets do not wait for a shortage to occur before reacting. Refiners bid for alternative crude, airlines secure cargoes months ahead, insurers raise premiums, and traders price the possibility that tomorrow’s supply will be worse than today’s.
This behaviour is rational at the level of the individual company. An airline that waits until fuel is physically unavailable has already failed. A refiner that assumes replacement cargoes will emerge eventually may be forced to shut down before they arrive.
Aggregated across the market, however, rational precaution can look like panic. Everyone competes for the same replacement barrels simultaneously, pushing physical prices far above futures benchmarks. During the early stages of the Hormuz crisis, some immediately deliverable crude grades approached $150 per barrel even while futures markets remained considerably lower.
Those prices then generated the very response that prevented the shortage. The premium attracted American exports, encouraged European refiners to alter yields and justified the cost of transporting fuel across much longer routes. High prices were not merely a symptom of the crisis; they were part of the mechanism through which the crisis was contained.
Markets therefore appear to overreact partly because their reaction changes the outcome. A prediction of severe scarcity drives behaviour that prevents the predicted scarcity from materialising.
Resilience Does Not Mean the Warnings Were Meaningless
It would nevertheless be wrong to conclude that the early warnings were fabricated or that Europe’s fuel security is stronger than previously believed. The IEA forecast was explicitly conditional: shortages could arise if Europe replaced only half of the missing Middle Eastern supply. Europe ultimately replaced more than that through emergency reserves, additional refinery production and imports from alternative regions.
The absence of widespread shortages is therefore not evidence that the original vulnerability was imaginary. It demonstrates that the response was effective.
The system also remains under pressure. European jet fuel inventories were estimated at only around 38 million barrels in early June, offering less than one month of demand coverage. Diesel markets are even tighter following Russia’s decision to restrict exports after attacks on its refining sector. European diesel margins have risen to exceptional levels, while inventories in both Europe and the United States remain below historical averages.
Europe has passed the original June deadline, but it has not escaped the crisis. It has converted the immediate risk of running out of fuel into a prolonged period of elevated costs and reduced buffers. A second major disruption would therefore begin from a weaker position than the first.
The Difference Between Scarcity and Expensive Abundance
This may be the central lesson of the Hormuz crisis so far. Modern energy systems are more resilient than their headline vulnerabilities suggest, but that resilience is primarily economic rather than comfortable.
Fuel remains available because consumers pay more, governments release reserves, refiners change production patterns and trade routes become longer. The system does not maintain normality; it prevents collapse by making scarcity expensive enough to mobilise alternatives.
From a consumer perspective, this can feel like failure. Airlines cut routes, ticket prices rise and diesel becomes more expensive even though no formal shortage exists. From the perspective of energy security, however, the distinction is significant. A high-priced market still allocates fuel. An empty market cannot.
The world has now absorbed a disruption that removed, at least temporarily, more oil supply than any previous crisis. That achievement reflects spare production outside the Gulf, strategic reserves, flexible refining, global shipping and weaker demand growth. It also reflects decades of diversification following earlier oil shocks.
Yet the public narrative remained focused on the date at which reserves were supposedly going to run out, rather than on the extraordinary industrial response taking place before that date arrived.
Panic Is Part of the System, but So Is Adaptation
Energy crises will always produce dramatic forecasts because the consequences of being unprepared are severe. Governments and companies should plan around adverse scenarios rather than assume markets will solve everything automatically. The strategic stock release, refinery adjustments and alternative sourcing that protected Europe did not occur by accident.
At the same time, the Hormuz experience should encourage greater scepticism towards countdown-style claims that a continent will “run out” of a globally traded commodity on a particular date. These projections often assume that production, trade and consumption remain unchanged while inventories fall. Once prices move sharply, almost none of those assumptions survive.
Europe did not emerge untouched. It paid more for oil, diesel and aviation fuel, depleted part of its emergency cushion and became dependent on longer and less efficient supply chains. The crisis also exposed weaknesses in European rules that require general oil reserves but do not guarantee adequate stocks of specific products such as jet fuel.
Nevertheless, the feared physical breakdown did not happen. The energy system bent, repriced and reorganised itself faster than expected.
That does not make the Strait of Hormuz unimportant, nor does it mean another escalation would be harmless. It does suggest that global energy markets are more adaptable than the first weeks of panic usually imply. The recurring mistake is to identify a serious vulnerability and then assume it must inevitably produce the worst possible outcome.
Hormuz has demonstrated something more complicated. The vulnerability was real, the disruption was historic and the warnings were understandable. Yet the world found new barrels, changed refinery output, redirected ships, released reserves and reduced demand before the predicted deadline arrived.
The energy market did what it often does during crises: it panicked first and adapted immediately afterwards.
A team of researchers from the University of Cambridge has managed to increase the efficiency of semiconductors by 70% for producing clean fuel using solar energy.

The search for economic alternatives to silicon has driven a profound optimization of semiconductor materials. A research team from the University of Cambridge has discovered that modifying the orientation of copper oxide crystals increases their energy efficiency, which allows devices to transform water into hydrogen using solar radiation.
The technical challenge of copper oxide
Historically, cuprous oxide has been considered an ideal candidate to replace silicon due to its abundance, low cost, and non-toxicity. However, the efficiency of this compound was limited by the loss of electrical charges in its internal structure before generating useful energy. Dr. Linfeng Pan, co-author of the study published in Nature, explained that the depth of light absorption did not match the distance traveled by the charges, which generated inactive zones within the material.
For this reason, scientists developed deposition techniques that allow high-quality cuprous oxide thin films to be grown at ambient temperature and pressure. By precisely controlling growth rates and fluxes in the chamber, cubic crystals were oriented in a specific direction. Likewise, high-resolution time-resolved spectroscopic analysis demonstrated that charges move faster when they follow the crystal body diagonal.
Diagonal orientation as a structural solution
Consequently, the electron path increased by a full order of magnitude, optimizing the overall performance of the photocathode device. Experimental tests recorded an improvement of over 70% compared to the most advanced electrodeposited oxide technologies currently on the market. The study authors highlighted that this geometric arrangement provides the system with much greater stability than usual, opening the door to more viable commercial use.
Therefore, the use of these optimized materials offers a clean pathway to move away from fossil fuels by leveraging existing energy infrastructure. Professor Sam Stranks, research director, noted that the discovery directly connects the fundamental physics of compounds with their real production capacity. Although technical development requires additional scaling phases, the advance consolidates an efficient alternative for large-scale clean fuel generation.

SINGAPORE (July 20): Copper nudged up slightly on Monday, supported by shrinking inventories and underwhelming supply from top producer Chile, while a weak demand outlook weighed.
Benchmark three-month copper on the London Metal Exchange rose 0.06% to US$13,533.5 a metric ton by 0710 GMT. The most-traded copper contract on the Shanghai Futures Exchange rose 0.2% to 104,020 yuan (US$15,361.44) a tonne.
The losses were limited by ongoing supply concerns, Daniel Hynes, ANZ senior commodity strategist, said in a note.
"BHP cut its copper production guidance for the year ahead after a mechanical failure at a South Australian mine and lower ore grades in Chile. This comes following data showing growth in Chile’s copper production remains elusive," said Hynes.
Mining major BHP Group last week flagged an expected decline in Chilean copper production next year.
Australian miner South32 missed fourth-quarter copper production on Monday, as inclement weather hampered mining operations at a Chilean project.
More broadly, Goldman Sachs said on Monday that it expects the ex-US copper market to remain tight in the near term. It added that if the Middle East conflict escalated further, adding to inflation and rate hike concerns, prices could face pressure.
Fighting between the US and Iran over the weekend fanned fears that higher inflation could lead to higher-for-longer interest rates, which could weigh on growth-dependent industrial minerals.
Meanwhile, copper inventories are waning. Available copper stocks on the LME have sharply declined amid a spree of warrant cancellations.
More than half of the copper in LME-registered warehouses was under cancelled warrants — indicating metal earmarked for withdrawal — as of Friday, exchange data showed.
The red metal has also been pulled into the US ahead of potential tariffs on refined copper.
Among other LME metals, aluminium dipped 0.24%, zinc lost 0.35%, lead lost 0.42%, nickel ticked 0.14% higher and tin gained 0.5%.
SHFE aluminium lost 0.95%, zinc lost 0.9%, lead dipped 0.16%, nickel lost 0.74% and tin gained 0.95%.

Cargo handled through Aqaba's ports and logistics facilities reached 13.3 million tonnes in the first half of 2026, up 12% from 11.83 million tonnes during the same period last year, according to data released by the Aqaba Special Economic Zone Authority (ASEZA) and the Aqaba Development Corporation (ADC).
The increase was largely driven by the Aqaba Multi-Purpose Port, where cargo volumes rose 61% year-on-year to 3.58 million tonnes, compared with 2.23 million tonnes a year earlier.
The port recorded higher volumes across several cargo categories. Grain handling increased 53% to more than 2.05 million tonnes, while general cargo rose 22%. Roll-on/roll-off cargo measured by weight increased 25%, livestock cargo by weight rose 40%, and the port also handled 468,600 tonnes of bulk sugar during the six-month period.
During the second quarter of 2026, cargo throughput at the Multi-Purpose Port reached approximately 2.29 million tonnes, representing a 97% increase compared with the second quarter of 2025.
At the Oil Port, cargo handling increased 53% to more than 2.2 million tonnes, from about 1.44 million tonnes in the corresponding period last year. The increase reflected higher volumes of gasoline, diesel and crude oil, which rose 75%, 32% and 21%, respectively.
General cargo handled through the Passenger Terminal rose 23% to 737,000 tonnes, while the number of roll-on/roll-off truck units increased 14%.
The LPG (liquefied petroleum gas) port recorded an 11% increase in throughput, with handled volumes reaching 337,300 tonnes.
Container traffic at the Aqaba Container Terminal totaled 472,681 TEUs during the first six months of 2026, up 1% year-on-year. Transit import containers increased 155%, while non-transit import container volumes declined 12% and export container handling decreased 3%.
Passenger traffic also recorded modest growth. The number of sea passengers passing through the Passenger Terminal rose 1% to 198,696, while passenger traffic at King Hussein International Airport increased 4% to 95,089.
Meanwhile, cargo handled at the Industrial Port remained broadly unchanged at around 2.78 million tonnes. Fertilizer handling increased 24%, ammonia rose 18%, and potash increased 3%, while sulfur and phosphoric acid volumes declined.
New Delhi [India], July 19 (ANI): Domestic finished steel consumption remained strong in the June quarter, supported by infrastructure spending, real estate activity, automobile manufacturing and heavy engineering demand, with demand outpacing production and resulting in India becoming a net importer of finished steel, according to an HDFC Securities Institutional Research Q1FY27 Results Preview report.
The report said, "Domestic consumption of finished steel (FS) in India remained healthy as it rose ~9% YoY in Q1FY27." It attributed the growth to "continued momentum in large-scale public infrastructure capex, steady demand from real estate and urban development projects, a rising demand from automotive manufacturing, and heavy engineering sectors." It added that "FS production growth was slower at 6% YoY, leading to net imports in Q1FY27."
On pricing, report said domestic hot-rolled coil (HRC) prices continued to strengthen during the quarter, while rebar prices moderated after mid-April. As a result, the brokerage expects steelmakers to report higher blended realisations for the quarter, although rising raw material costs are likely to temper margin gains.
The report said, "While domestic HRC (flats) continued to trend higher in Q1FY27, rebar (longs) witnessed a cool-off mid-April'26 onward."
It added, "We estimate steel companies will continue to deliver higher blended realisation QoQ in Q1FY27."
However, "Steel companies will also report higher cost of production (CoP) as both coking coal and iron ore prices are on a rise," with coking coal prices expected to increase by around USD 15-20 per tonne quarter-on-quarter and iron ore prices by about Rs 300 per tonne. "These should moderate the gross and EBITDA margin expansions from robust pricing gains," the report said.
Despite higher input costs, the brokerage firm maintained a positive outlook on the domestic steel sector, citing healthy demand and supportive pricing. (ANI)
