A new coating for lithium-ion batteries (LIBs), developed by scientists at UNIST promises extended driving for future electric vehicles (EVs).
At the heart of clouds are ice crystals. And at the heart of ice crystals, often, are aerosol particles - dust in the atmosphere onto which ice can form more easily than in the open air.
The use of fossil fuels as energy carriers and raw materials promotes the rapid development of the society. However, the excessive exploitation of fossil fuels gives rise to the energy crisis and undesirable environmental changes.
The diesel engine is the backbone of transportation due to its irreplaceability as the primary power source for the freight, navigation and marine engine industries and non-road engineering machinery for the foreseeable future.
When hydrogen is separated from water using solar light rather than fossil fuels, it becomes a non-polluting energy source.
As researchers push the boundaries of battery design, seeking to pack ever greater amounts of power and energy into a given amount of space or weight, one of the more promising technologies being studied is lithium-ion batteries that use a solid electrolyte material between the two electrodes, rather than the typical liquid.
A strong bias towards linear and disc-shaped molecules has long been observed in drug molecules. In contrast, spherical molecules have been utilized on far fewer occasions, due to the lack of efficient access to the latter chemical space. Specifically, efficient strategies to synthesize tetraarylmethanes, a unique family of spherical molecules, have remained scarce.
Fuel cells, which are attracting attention as an eco-friendly energy source, obtain electricity and heat simultaneously through the reverse reaction of water electrolysis. Therefore, the catalyst that enhances the reaction efficiency is directly connected to the performance of the fuel cell. To this, a POSTECH-UNIST joint research team has taken a step closer to developing high-performance catalysts by uncovering the ex-solution and phase transition phenomena at the atomic level for the first time.
Gas and liquid separation processes in the chemical industry could be made more efficient and environmentally friendly by using substances known as intrinsically porous materials (IPMs). KAUST researchers review the prospects for IPMs in the journal Accounts of Chemical Research.
A research team at Johannes Gutenberg University Mainz (JGU) in Germany has developed a completely new, environmentally-friendly electrochemical procedure for producing sulfonamides rapidly and inexpensively. Sulfonamides are used in many drugs including antibiotics and Viagra as well as in agrochemicals and dyes, which makes them an important class of molecules for the pharmaceutical and chemical industries.
