Aryl radical formation by aryl halide bond cleavage by a N-heterocyclic carbene catalyst
Aryl halides with a benzene ring directly bonded to a halogen atom are readily available and chemically stable, so they are used as a source of benzene rings in organic synthesis. For example, a chemical reaction that generates a highly reactive aryl.....»»
Researchers investigate the surface extraction of platinum catalysts in alkaline media
Platinum (Pt) electrodes are crucial for clean power technologies like hydrogen fuel cells and electrolysis. However, the surface oxidation that occurs during such processes degrades catalyst performance and stability......»»

Artificial mucus identifies link to tumor formation
During cold and flu season, excess mucus is a common, unpleasant symptom of illness, but the slippery substance is essential to human health. To better understand its many roles, researchers synthesized the major component of mucus, the sugar-coated.....»»
Photocatalytic synthesis of arylacetic acid via C=C double bond cleavage with carbon dioxide
Alkenes represent one of the most abundant classes of organic molecules, which are available in bulk quantities from petroleum and renewable resources, with various utilization in agrochemistry, pharmacy, and organic materials. Typically, the transfo.....»»
Direct laser writing on halide perovskites: From mechanisms to applications
Metal halide perovskites have become well-deserved "star" materials among a variety of semiconductors owing to their excellent optoelectronic properties, such as high photoluminescence (PL) quantum yield (QY), high absorption coefficient, tunable ban.....»»
New catalyst accelerates release of hydrogen from ammonia
Germany can probably only meet its demand for climate-friendly hydrogen by imports, for example, from South America or Australia. For such long-distance transport, hydrogen can be converted into ammonia......»»
