It's elemental—scientists agree that the periodic table is incomplete.
阅读全文Ethylene is one of the most important building blocks in chemical synthesis. Traditional thermocatalytic hydrogenation of acetylene to ethylene (HAE) requires high temperatures and high pressure, lead...
阅读全文Methane, which produces more warming than other greenhouse gasses and is the subject of newly announced U.S. emission restrictions, is hard to break down and keep out of the atmosphere.
阅读全文Between 118 and 138 million tons of organic waste are generated annually worldwide, with waste from the food production and distribution chain accounting for 100 million tons of the total. Only about ...
阅读全文Some studies have shown that nicotine, an addictive substance in electronic cigarettes, increases the risk of cardiovascular and respiratory disorders. But to get a full understanding of its potential...
阅读全文Over the years, hundreds of new synthetic drugs that mimic the effects of illegal and legal substances have emerged. The underground nature of each drug's development and distribution makes its intern...
阅读全文Researchers have discovered a new way to make crystals stretchy, a modification that could enable them to act as very effective nanofilters.
阅读全文Measuring plant phenotypes, a term used to describe the observable characteristics of an organism, is a critical aspect of studying and improving economically important crops. Phenotypes central to th...
阅读全文Most are aware that electrons are negatively charged particles that surround the nucleus of atoms and whose behaviour governs chemical interactions. However, it is less commonly known that electrons c...
阅读全文The group at Polymeric Materials has developed a simple way to regulate both dispersity and sequence in highly complex multiblock copolymers, and the results have been published in Nature Chemistry.
阅读全文Discontinuous atmospheric pressure interface (DAPI), consisting of a pinch valve, a silicone tube, and two metal capillaries, is a common inlet for miniature ion trap mass spectrometers (ITMS). It c...
阅读全文An international team of researchers has solved one of the fundamental mysteries in catalysis: The paradox of structure insensitivity. To make better catalysts, researchers have long been studying the...
阅读全文Where and how did life begin on Early Earth more than 3.5 billion years ago from non-living chemicals? A key necessity for the first cells on Earth is the ability to make compartments and evolve to fa...
阅读全文Using a modified, lower temperature mashing procedure to retain enzyme activity, brewers can use malts from gluten-free grains to produce high-quality beers, according to Penn State researchers who co...
阅读全文A beam of light can be divided into left-handed and right-handed polarized light by physical methods. Chiral fluorescent materials can emit different left-handed and right-handed polarized light when ...
