Published Mathematical innovations enable advances in seismic activity detection



Scientists successfully addressed mathematical challenges in conventional Spectral Matrix analysis, used to analyze three-component seismic signals, by introducing time-delay components. The new technique enables the characterization of various polarized waves and the detection of seismic events that have previously gone unnoticed by conventional methods. These findings pave the way for improving a variety of applications, including earthquake detection.
Published Research lights up process for turning CO2 into sustainable fuel



Researchers have successfully transformed CO2 into methanol by shining sunlight on single atoms of copper deposited on a light-activated material, a discovery that paves the way for creating new green fuels.
Published Pairing crypto mining with green hydrogen offers clean energy boost



Pairing cryptocurrency mining -- notable for its outsize consumption of carbon-based fuel -- with green hydrogen could provide the foundation for wider deployment of renewable energy, such as solar and wind power, according to a new study.
Published Researchers take major step toward developing next-generation solar cells



Engineers have discovered a new way to manufacture solar cells using perovskite semiconductors. It could lead to lower-cost, more efficient systems for powering homes, cars, boats and drones.
Published Revolutionizing hydrogen production: Economical and efficient solutions unveiled



Scientists introduce superaerophobic three-dimensional nickel nanostructured catalysts for accelerated water electrolysis.
Published Research suggests how turbulence can be used to generate patterns



Physicists show how patterns can emerge from chaos in turbulent fluids.
Published Harnessing hydrogen at life's origin



A new report uncovers how hydrogen gas, the energy of the future, provided energy in the past, at the origin of life 4 billion years ago. Hydrogen gas is clean fuel. It burns with oxygen in the air to provide energy with no CO2. Hydrogen is a key to sustainable energy for the future. Though humans are just now coming to realize the benefits of hydrogen gas (H2 in chemical shorthand), microbes have known that H2 is good fuel for as long as there has been life on Earth. Hydrogen is ancient energy.
Published Reimagining the future of solar energy



New research suggests that there might be other ways to generate solar energy than just trying to make individual solar cells super-efficient.
Published Perovskite solar cells: Vacuum process may offer a short track to commercialization



Which process is best suited for mass production of perovskite solar cells? While solvent-based manufacturing processes are used in laboratories around the world, vacuum vapor-phase deposition processes are still the standard for the production of thin films for photovoltaics or organic light-emitting diodes. A new study that reveals major differences in the scientific discussion of these production processes.
Published What kinds of seismic signals did Swifties send at LA concert?



Seattle may have experienced its own Swift Quake last July, but at an August 2023 concert Taylor Swift's fans in Los Angeles gave scientists a lot of shaking to ponder. After some debate, a research team concluded that it was likely the dancing and jumping motions of the audience at SoFi Stadium -- not the musical beats or reverberations of the sound system -- that generated the concert's distinct harmonic tremors.
Published 'Find pearls in the soil' unveiling the magic of hydrogen production from municipal sewage



Scientists have developed a catalyst for the urea oxidation reaction, enhancing hydrogen generation efficiency.
Published New high-performance solar cell material



A new study reports the discovery of an entirely new stable, earth-abundant, high-performance material for solar absorbers -- the central part of a solar cell that turns light into electricity. While identifying new solar materials is typically very time-consuming, the researchers used a unique high-throughput computational screening method to quickly evaluate around 40,000 candidate materials.

A team of researchers has revealed ways to optimize efficiency and better control degradation, by engineering the nanoscale structure of perovskite devices.
Published Researchers improve the stability of perovskite solar cells



Perovskite solar cells are considered the strongest contender to replace silicon solar cells. While they achieve high power conversion energy, they also suffer from lead leakage and perovskite degradation due to moisture. Now scientists leverage the technique of interfacial passivation, where lead ions are bound by crown ether B18C6, obtaining 21.7% power conversion energy. The crown ether also resists degradation due to moisture for 300 hours at room temperature and 85% humidity.
