Catalytic synthesis of phenols with nitrous oxide
The emission of greenhouse gases threatens the global environment, and scientists around the world are increasingly committed to addressing this issue. While many research groups focus on carbon dioxide (CO2) or methane (CH4) revalorization strategie.....»»
Estuaries as climate gas hotspots
Nitrous oxide has a much stronger effect on the climate than carbon dioxide. Soils, peatlands and rivers are potential nitrous oxide sources. However, when, where and how much nitrous oxide is emitted into the air has not yet been sufficiently resear.....»»
How a transparent conductor responds to strain
Liquid crystal displays, touchscreens, and many solar cells rely on thin-film crystalline materials that are both electrically conductive and optically transparent. But the material most widely used in these applications, indium tin oxide (ITO), is b.....»»

A new Achilles heel of the bacterial cell wall
The bacterial cell wall must be constantly remodeled in order to grow and divide. This involves the close coordination of lytic enzymes and peptidoglycan synthesis. In their study published in Nature Communications, researchers led by Martin Thanbich.....»»
Better synthesis of geospatial data may help combat poachers, scientists say
Poaching wild animals poses global environmental risks, from threatening the survival of keystones species to potentially spreading animal-borne diseases to humans. Technology like unmanned aerial vehicles, or drones, can help combat poachers, but fi.....»»
Scientists overcome NH3 synthesis shortcomings
NH3 is not only the key chemical raw material for the industry but also a carbon-free fuel and mobile carrier of renewable energy in the future. So far, industrial NH3 synthesis is still dominated by the traditional Haber-Bosch reaction, which requir.....»»

Simultaneous synthesis and fixing of covalent organic frameworks
Covalent organic frameworks (COFs) are versatile materials composed of interconnected organic molecules held together by covalent bonds. These frameworks can be constructed in two-dimensional or three-dimensional (3D) forms which possess a unique com.....»»
Aggregation-induced catalysis: Asymmetric catalysis with chiral aggregates
Asymmetric synthesis and catalysis have been actively pursued in chemical and materials sciences for some time. Increasing numbers of drugs and pesticides contain chiral structural units in their structures since drug actions require conformational m.....»»
Unimolecular reactions of anti-glycolaldehyde oxide and its reactions with one and two water molecules
Criegee intermediates are produced in the ozonolysis of unsaturated compounds in the atmosphere. These intermediates are especially important because they contribute to the formation of OH radicals during the night and to the formation of secondary o.....»»
Thanks to trapped electrons, a material expected to be a conducting metal remains an insulator
New research sheds light on the mechanism behind how a special material changes from an electrically conducting metal to an electric insulator. The researchers studied lanthanum strontium nickel oxide (La1.67Sr0.33NiO4) derived from a quantum materia.....»»
