A thermos bottle has the task of preserving the temperature - but sometimes you want to achieve the opposite: Computer chips generate heat that must be dissipated as quickly as possible so that the chip is not destroyed. This requires special materials with particularly good heat conduction properties.
A simple plastic water bottle isn't so simple when it comes to the traditional manufacturing process. To appear in its final form, it has to go through a multi-step journey of synthetic procedure, casting, and molding. But what if materials scientists could tap into the same biological mechanisms that create the ridges on our fingertips or the spots on a cheetah in order to manufacture something like a water bottle-
At the Washington University in St. Louis, scientists have announced the first-ever observations of a new form of fluorine, called the isotope 13F.
Materials such as gallium arsenide are extremely important for the production of electronic devices. As supplies of it are limited, or they can present health and environmental hazards, specialists are looking for alternative materials.
A newly developed, highly active carbon framework-encapsulated copper oxide Fenton-like catalyst exhibits the potential to produce singlet oxygen and free radicals by activating peroxymonosulfate (PMS), thereby achieving efficient disintegration of tetracycline pollutants in water.
A new catalyst for the conversion of carbon dioxide (CO2) into chemicals or fuels has been developed by researchers at Ruhr-Universität Bochum and the University of Duisburg-Essen. They optimized already available copper catalysts to improve their selectivity and long-term stability.
Atomically dispersed catalysts have received extensive research attention, because they exhibit excellent activity and unique selectivity for many important catalytic reactions.
Using electricity to split water into hydrogen and oxygen can be an effective way to produce clean-burning hydrogen fuel, with further benefits if that electricity is generated from renewable energy sources.
Decreasing the emission and efficient utilization (fixation) of carbon dioxide (CO2) are worldwide issues to prevent global warming. Promotion of the use of renewable energy is effective in reducing CO2 emissions.
Chemists from RUDN University found out that fluorine and fluoroalkyl groups increase the efficiency of catalysts in metathesis reactions that are used in the pharmaceutical industry and polymer chemistry. The team also identified fluorine-containing compounds that can simplify the purification of the catalyst from the reaction product, making it reusable. The results of the study were published in the Russian Chemical Reviews journal.
