Published Harnessing hydrogen at life's origin
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 'Find pearls in the soil' unveiling the magic of hydrogen production from municipal sewage
(via sciencedaily.com) Original source Scientists have developed a catalyst for the urea oxidation reaction, enhancing hydrogen generation efficiency.
Published New high-performance solar cell material
(via sciencedaily.com) Original source 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.
Published Lost tombs and quarries rediscovered on British military base in Cyprus
(via sciencedaily.com) Original source Archaeologists rediscovers 46 sites at the Eastern Sovereign Base Area at Dhekelia, Cyprus. Archaeologists located sites from archive records, a number of which were thought to have been 'lost.' They uncovered evidence of quarries and tombs likely to span from the Bronze Age, Byzantine, Hellenistic and Roman periods.
Published Breakthrough research enables high-density hydrogen storage for future energy systems
(via sciencedaily.com) Original source A research team has reported a groundbreaking development in efficient hydrogen storage.
Published Evolving hydrogen-storage technology: Guidelines developed for the design of anti-evaporation catalysts
(via sciencedaily.com) Original source A research team has identified materials capable of catalyzing the conversion of ortho-hydrogen to para-hydrogen. These catalysts should be essential to the spread of mass-transportation/storage of liquid hydrogen.
Published Researchers invent new triple-junction tandem solar cells with world-record efficiency
(via sciencedaily.com) Original source Scientists have developed a novel triple-junction perovskite/Si tandem solar cell that can achieve a certified world-record power conversion efficiency of 27.1 per cent across a solar energy absorption area of 1 sq cm, representing the best-performing triple-junction perovskite/Si tandem solar cell thus far. To achieve this, the team engineered a new cyanate-integrated perovskite solar cell that is stable and energy efficient.
Published Scientists ID burned bodies using technique used for extracting DNA from woolly mammoths, Neanderthals
(via sciencedaily.com) Original source A technique originally devised to extract DNA from woolly mammoths and other ancient archaeological specimens can be used to potentially identify badly burned human remains, according to research.
Published Study unlocks nanoscale secrets for designing next-generation solar cells
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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.
Published Slimming down a colossal fossil whale
(via sciencedaily.com) Original source A 30 million year-old fossil whale may not be the heaviest animal of all time after all, according to a new analysis by paleontologists. The new analysis puts Perucetus colossus back in the same weight range as modern whales and smaller than the largest blue whales ever recorded.
Published Climate change threatens thousands of archaeological sites in coastal Georgia
(via sciencedaily.com) Original source Thousands of historic and archaeological sites in Georgia are at risk from tropical storm surges, and that number will increase with climate change, according to a new study.
Published Researchers closer to understanding hydrogen's great challenge
(via sciencedaily.com) Original source Embrittlement is one of the biggest obstacles facing the transition to a global hydrogen economy. A new process uncovered by researchers is helping shed light on how to better prevent it.
Published Experiment captures why pottery forms are culturally distinct
(via sciencedaily.com) Original source Potters of different cultural backgrounds learn new types differently, producing cultural differences even in the absence of differential cultural evolution. The research has implications for how we evaluate the difference of archaeological artifacts across cultures.
Published New study unveils scalable and efficient photoelectrode modules for green hydrogen production
(via sciencedaily.com) Original source A recent study has achieved a remarkable technological breakthrough in the production of green hydrogen.
Published Researchers use Hawk supercomputer and lean into imperfection to improve solar cell efficiency
(via sciencedaily.com) Original source Solar energy is one of the most promising, widely adopted renewable energy sources, but the solar cells that convert light into electricity remains a challenge. Scientists have turned to the High-Performance Computing Center Stuttgart to understand how strategically designing imperfections in the system could lead to more efficient energy conversion.
Published What will it take for China to reach carbon neutrality by 2060?
(via sciencedaily.com) Original source To become carbon neutral by 2060, China will have to build eight to 10 times more wind and solar power installations than existed in 2022, according to a new study. Reaching carbon neutrality will also require major construction of transmission lines.
Published Plant seed and fruit analysis from the biblical home of Goliath sheds unprecedented light on Philistine ritual practices
