Purely organic room-temperature phosphorescence (RTP) materials have been a hot research topic. Currently, the pure RTP materials have been realized by the introduction of heavy halogen atoms, carbonyls groups or some heteroatoms, hydrogen bonding, H-aggregation, strong intermolecular electronic coupling, molecular packing, host-guest interaction, etc.
The directly catalytic oxidation of alkanes has high atomic economy and application value to form corresponding chemical organic products such as alcohols, aldehydes, ketones and carboxylic acid. It is challenging to achieve efficient and selective oxidation of alkane under mild conditions due to the inert C-H bonds of alkanes.
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.
