Mechanism of cobalt–manganese catalysts deciphered
Conventional catalysts for hydrogen production via water electrolysis usually contain precious metals and are expensive. However, cheaper alternatives have been developed, for example cobalt–manganese catalysts. They have a high activity and are st.....»»
Researchers decipher the structure of protein methyltransferase from the mpox virus
Scientists from the Institute of Organic Chemistry and Biochemistry in Prague have deciphered the structure of the protein methyltransferase from the monkeypox virus. It is with the help of this protein that the virus escapes human immunity and cause.....»»
Scientists slow aging by engineering longevity in cells
Human lifespan is related to the aging of our individual cells. Three years ago a group of University of California San Diego researchers deciphered essential mechanisms behind the aging process. After identifying two distinct directions that cells f.....»»
Record ammonia production achieved with inexpensive cobalt catalyst at low temperatures
Ammonia (NH3) is one of the most widely produced chemicals in the world, with production at more than 187 million tons in 2020. About 85% of it is used to produce nitrogenous fertilizers, while the rest is used for refining petroleum, manufacturing a.....»»
Unraveling the mechanism of green emission peaks in single polyfluorene chains
Molecular aggregates are clusters of small molecules held together by relatively weak forces believed to be originating from electronic interactions between the molecules. Owing to their exceptional photophysical properties, molecular aggregates find.....»»
Gene that confers seed tolerance to salinity identified
Seeds only germinate when a series of internal and environmental needs are met. Otherwise, they get stuck in a state of dormancy. Researchers from the Instituto Gulbenkian de Ciência (IGC) led by Paula Duque just revealed a mechanism that allows pla.....»»
