Researchers synthesize graphene using intense light
DGIST Professor Yoonkyu Lee's research team used intense light on the surface of a copper wire to synthesize graphene, thereby increasing the production rate and lowering the production cost of the high-quality transparent-flexible electrode material.....»»
Breaking the barrier: Low-temp ammonia synthesis with iron catalysts and barium hydride
The Haber-Bosch (HB) process is one of the most important industrial chemical reactions. It combines nitrogen and hydrogen gases in the presence of an iron-based catalyst at high temperatures and pressures to produce ammonia fertilizer which helps pr.....»»
An improved, visible light-harvesting catalyst to speed up reactions
Photocatalysis is the use of light to accelerate the rate of a reaction in the presence of a photocatalyst. The catalyst plays a crucial role in this process—it absorbs the light being shined onto it and makes it available in ways that can help acc.....»»
Highly charged ions melt nano gold nuggets
Normally, we have to make a choice in physics: Either we deal with big things—such as a metal plate and its material properties, or with tiny things—such as individual atoms. But there is also a world in between: The world of small but not yet ti.....»»
Major Taiwan IC design houses vary strategies amid slowdown
Major Taiwan-based IC design houses such as MediaTek, Novatek Microelectronics, Realtek Semiconductor, Elan Microelectronics, Parade Technologies, and Global Mixed-mode Technology (GMT) are responding to the market slowdown in their own ways, but all.....»»
Students who played sports before the pandemic did better during lockdowns
A history of participating in campus recreational sports can offset stress and contribute to academic competence even during high-stress periods such as a pandemic lockdown, shows a new study......»»
Freshwater ecosystems are becoming increasingly salty, say researchers
Freshwater ecosystems around the world are becoming saltier and saltier. Many human-driven factors contribute to freshwater salinization, including: irrigation, oil extraction, potash mining, and road de-icing......»»
Using a genetic algorithm to uncover new catalyst molecules for organic synthesis
A team of researchers have used a computational method inspired by evolution to discover an organic catalyst with better performance than known catalysts. As the team reports in the journal Angewandte Chemie International Edition, a genetic algorithm.....»»
Lithium, nickel prices on decline as China demand slows
Nickel, copper, and aluminum prices have fallen to their lowest points in months. Lithium carbonate, a key material for EV batteries, also plunged as supply outpaces demand......»»
Novel catalyst for highly selective photoelectroreduction of carbon dioxide to ethanol
Artificial photosynthesis (AP), using sunlight to produce valuable chemicals and fuels from carbon dioxide (CO2), is a promising strategy to achieve solar energy storage as well as negative carbon cycle......»»
Excavations reveal copper deposits that made Cyprus one of the most important Late Bronze Age trade hubs
Excavations led by researchers from the University of Gothenburg show that the coveted metal copper and a sheltered location turned the Cypriot village of Hala Sultan Tekke into one of the most important trade hubs of the Late Bronze Age. The researc.....»»
Producing synthetic gas from atmospheric carbon dioxide using a transition-metal-free catalyst
Japan has declared carbon neutrality by 2050 as a government target to reduce net greenhouse gas emissions to zero by 2050. In order to substantially reduce CO2 emissions, it is important not only to control CO2 emissions through existing processes,.....»»
US public water supply is a local source of phosphorus pollution, finds study
In the United States, public water systems are sometimes dosed with phosphate to reduce copper levels and lead pipe corrosion. This practice can help avert humanitarian disasters like the Flint water crisis, but because phosphorus can contribute to e.....»»
