Published Moving beyond the 80-year-old solar cell equation



Physicists have made a significant breakthrough in solar cell technology by developing a new analytical model that improves the understanding and efficiency of thin-film photovoltaic (PV) devices.
Published Solar technology: Innovative light-harvesting system works very efficiently



Researchers are reporting progress on the road to more efficient utilization of solar energy: They have developed an innovative light-harvesting system.
Published Iceland's volcano eruptions may last decades



Scientists predict from geochemical data that Iceland is entering a new volcanic era that will last for decades, possibly centuries. Under an hour's drive from the country's capital city, the ongoing eruptions pose considerable risks for economic disruption, and they leave evacuated communities uncertain of a possible return.
Published Promise green hydrogen may not always be fulfilled



Green hydrogen often, but certainly not always, leads to CO2 gains.
Published New material puts eco-friendly methanol conversion within reach



Researchers have developed innovative, eco-friendly quantum materials that can drive the transformation of methanol into ethylene glycol. This discovery opens up new possibilities for using eco-friendly materials in photocatalysis, paving the way for sustainable chemical production.
Published An earthquake changed the course of the Ganges: Could it happen again?



A major earthquake 2,500 years ago caused one of the largest rivers on Earth to abruptly change course, according to a new study. The previously undocumented quake rerouted the main channel of the Ganges River in what is now densely populated Bangladesh, which remains vulnerable to big quakes.
Published Lab achieves major gains in perovskite solar cell stability



Researchers have developed new chemistry to achieve commercially relevant stability and performance for perovskite solar cells.
Published The rotation of Earth's inner core has slowed, new study confirms



The new study provides unambiguous evidence that the inner core began to decrease its speed around 2010, moving slower than the Earth's surface.
Published Estimating the energy of past earthquakes from brecciation in a fault zone



In the same way that the number of rings in a tree can tell us its age, the characteristics of rocks such as breccia can tell us about the history of a region. The breccia around Ichinokawa Mine (located in Ehime prefecture) are of particular interest, as the mine is located south of the Median Tectonic Line. Researchers uncovered how breccia can provide valuable evidence to estimate the energy of past earthquakes in the area.
Published A 'liquid battery' advance



A team aims to improve options for renewable energy storage through work on an emerging technology -- liquids for hydrogen storage.
Published Algae offer real potential as a renewable electricity source



The need to transition away from fossil fuels to more sustainable energy production is critical. That's why a team of researchers is looking at a potential power source that not only produces no carbon emissions but removes carbon as it works: algae.
Published Cascadia Subduction Zone, one of Earth's top hazards, comes into sharper focus



A new study has produced the first comprehensive survey of the many complex structures beneath the seafloor in the Cascadia Subduction Zone, off British Columbia, Washington, Oregon and California. It is providing scientists with key insights into how future disasters may unfold.
Published Breaking ground: Could geometry offer a new explanation for why earthquakes happen?



Researchers are adding a new wrinkle to a long-held belief about what causes earthquakes in the first place.
Published Some countries could meet their total electricity needs from floating solar panels



Floating solar photovoltaic panels could supply all the electricity needs of some countries, new research has shown. The researchers calculated the daily electrical output for floating photovoltaics (FPV) on nearly 68,000 lakes and reservoirs around the world, using available climate data for each location.
Published Enhancing nanofibrous acoustic energy harvesters with artificial intelligence



Scientists have employed artificial intelligence techniques to improve the design and production of nanofibers used in wearable nanofiber acoustic energy harvesters (NAEH). These acoustic devices capture sound energy from the environment and convert it into electrical energy, which can then be applied in useful devices, such as hearing aids.
Published New method makes hydrogen from solar power and agricultural waste



Engineers have helped design a new method to make hydrogen gas from water using only solar power and agricultural waste such as manure or husks. The method reduces the energy needed to extract hydrogen from water by 600%, creating new opportunities for sustainable, climate-friendly chemical production.
Published Safeguarding urban infrastructure from subsidence and liquefaction risks



During an earthquake, soil can weaken through subsidence and liquefaction. These processes can cause buildings to collapse as the soil becomes unable to support their weight. Researchers have now developed a model that predicts soil-bearing strength and thickness to identify stable construction sites and reduce structural risks. Additionally, the model can also predict other soil conditions in real-time and function as an early-warning system to identify potential hazards.
Published Wind farms are cheaper than you think -- and could have prevented Fukushima, says global review



Offshore wind could have prevented the Fukushima disaster, according to a review of wind energy.
Published Understanding the mechanisms for local amplification of 2024 tsunamis in Iida Bay



Researchers uncover the unique mechanisms that resulted in severe tsunamis in Iida Bay caused by the 2024 Noto Peninsula Earthquake. The recent tsunamis in Iida Bay were locally amplified due to various factors, including ocean floor topology, the shape of the coastline, the location of coastal facilities, and seismic mechanisms associated with earthquakes, report scientists.
Published What are the risks of hydrogen vehicles in tunnels?



A team has analyzed the risk and damage potential of hydrogen vehicles in tunnels and derived recommendations. Their conclusion? Any damage would be extensive, but its occurrence is unlikely.
