    Chemists Orchestrate The Molecular Union of Two Single Atoms

    via Wired: THE MAIN ACT of Kang-Kuen Ni’s experiment could fit on the tip of a needle—and it happens in a fraction of a second. The Harvard chemist takes two individual atoms, a sodium and a cesium, each about 10,000 times smaller than a bacterium. Then, very carefully, she brings them together to become a single molecule: sodium cesium. It’s an unlikely pairing. In the cosmic rom-com that is nature, sodium rarely goes for cesium; both […]

    Chemistry in Pictures: Fine-Tuned Glow

    via c&en: Biologists use fluorescent dyes to stain and image biological tissues using specialized microscopes. Luke Lavis’s group at the Howard Hughes Medical Institute’s Janelia Research Campus recently came up with a new, milder synthesis for rhodamines, a popular class of dyes, using a palladium catalyst (Nat. Methods. 2017, DOI: 10.1038/nmeth.4403). With this new method, they were able to prepare rhodamines decorated with four-membered azetidine rings, which boost the efficiency of the dyes’ fluorescence. By changing […]

    Boffins Discover Chemistry That Could Have Produced Building Blocks of Life in Space

    via The Register: A team of researchers carried out a series of experiments to study how complex hydrocarbons, an important class of molecules needed to create the building blocks for life, formed in space. Hydrocarbons, compounds made up of differing amounts of carbon and hydrogen, are common on Earth but also outside it. Some hydrocarbons, such as benzene or naphthalene, have been detected in meteorites floating around the solar system, leading scientists to wonder how they […]

    Chemistry May Yield Lucrative Use for Wasted Methane

    via Scientific American: Methane that leaks from fracking wells can be captured and converted into a product used in plastics manufacturing. Methane that leaks from fracking wells can be captured and converted into a chemical used in plastics manufacturing. New research from the University of Southern California has found that wasted methane, a powerful greenhouse gas that drives climate change, can be efficiently converted into a valuable new product. The study, published recently in the Journal […]

  • New method developed to detect bacteria in food and water

    New method developed to detect bacteria in food and water

    via NEWS MEDICAL: Researcher Lili He and colleagues at the University of Massachusetts Amherst have devised a low cost, easy to administer method that could help detect the presence of bacteria in food and water samples. This would be a boon for aid workers in areas affected by natural disasters where food and drinking water conditions are at high risk. It would also be very useful for cooks and chefs to ensure food safety, explained He. […]

  • Life On Earth Began With A Strange Change In Chemistry, New Theory Proposes

    Life On Earth Began With A Strange Change In Chemistry, New Theory Proposes

    via Newsweek : Scientists believe that life on Earth first formed about 3.8 billion years ago with simple, single-celled organisms. But how did the complex processes necessary for life begin in the first place? Scientists from NASA and the National Science Foundation have found a possible explanation of how the citric acid cycle, or the Krebs cycle, could have formed in early Earth. Every aerobic organism on Earth today needs the Krebs cycle, which uses a […]

  • The Chemical Reaction That Cleans Everything

    The Chemical Reaction That Cleans Everything

    via The New York Times : Q. What exactly does bleach do? If I soak a cracked dish, the stains seem to be gone — but are they really? A. The active ingredient of bleach is sodium hypochlorite, which is made up of three common elements, sodium, oxygen and chlorine, said May Nyman, professor of chemistry at Oregon State University. The rest of what is in the bleach bottle is mostly water. “Of those three […]

    Breaking The Chain—Catalyzing A Green Future For Chemistry

    via Phys.org : Osaka University researchers create catalyst for refining chemicals in plant waste, allowing a green way to produce valuable raw materials. The fight against climate change is a call-to-arms for industry. We currently rely on fossil fuels, a major source of the greenhouse gas CO2, not only for energy but also to create chemicals for manufacturing. To ween our economies off this dependency, we must find a new source of “green” raw materials so […]

  • The Intricate Dance of Chemical Reactions: Chemical Kinetics to Chemical Dynamics

    The Intricate Dance of Chemical Reactions: Chemical Kinetics to Chemical Dynamics

    via Decoded Science : Some chemical reactions seem to occur within a blink of an eye, while others take place over long time frames. The rate (speed) at which a reaction proceeds is fundamental to all chemistry, but particularly in the areas of kinetics and chemical dynamics. As sub-disciplines of physical chemistry, kinetics and chemical dynamics are concerned with the measurement of reaction rates, and most notably, for controlling the end products of a reaction. The […]

  • Seeing the Invisible World with the 2017 Nobel Prize in Chemistry

    Seeing the Invisible World with the 2017 Nobel Prize in Chemistry

    via The New Yorker : Chemistry sits halfway between physics and biology; it’s the middle child in the scientific family, as dependable as it is overshadowed. On Monday, the Nobel Prize in Physiology or Medicine was awarded to three researchers who helped elucidate the mechanics of circadian rhythms, the gene-based clocks within our cells; on Tuesday, the physics prize honored the discovery, finally confirmed in 2016, of gravitational waves. By the time chemistry rolled around, […]
