    Chemistry in Pictures: Shining Better Together

    via c&en: Before Yujie Tu crystallized this anthracene derivative, it hardly glowed at all. In the closely packed structure of the crystals, the molecules clumped together, locking down squirmy parts of the molecules that would otherwise absorb light and thus prevent fluorescence. Tu studies this phenomenon, called aggregate-induced emission, as part of his PhD work at Hong Kong University of Science and Technology. Finding organic molecules that glow when they clump together is useful in biological […]

  • Chemical synthesis could produce more potent antibiotics

    Chemical synthesis could produce more potent antibiotics

    via MIT News: Using a novel type of chemical reaction, MIT researchers have shown that they can modify antibiotics in a way that could potentially make them more effective against drug-resistant infections. By chemically linking the antibiotic vancomycin to an antimicrobial peptide, the researchers were able to dramatically enhance the drug’s effectiveness against two strains of drug-resistant bacteria. This kind of modification is simple to perform and could be used to create additional combinations of antibiotics […]

  • Self-healing material can build itself from carbon in the air

    Self-healing material can build itself from carbon in the air

    via MIT News: A material designed by MIT chemical engineers can react with carbon dioxide from the air, to grow, strengthen, and even repair itself. The polymer, which might someday be used as construction or repair material or for protective coatings, continuously converts the greenhouse gas into a carbon-based material that reinforces itself. The current version of the new material is a synthetic gel-like substance that performs a chemical process similar to the way plants incorporate […]

  • Scientists discover natural plant-based food preservative

    Scientists discover natural plant-based food preservative

    via Phys: Nanyang Technological University, Singapore (NTU Singapore) scientists have discovered a plant-based food preservative that is more effective than artificial preservatives. The organic preservative comprises naturally occurring flavonoids, a diverse group of phytonutrients found in almost all fruits and vegetables. The flavonoids created by NTU scientists have strong antimicrobial and antioxidant properties, two key traits of preservatives that inhibit bacterial growth and extend food freshness. In tests carried out on on meat and fruit juice […]

  • Supercomputing The ‘How’ of Chemical Reactions

    Supercomputing The ‘How’ of Chemical Reactions

    via Science Daily: Sometimes, when experimental scientists get their hands on a supercomputer, it can change the course of their careers and open up new questions for exploration. This was the case with Abdurrahman and Tülay Atesin, husband and wife chemists, collaborators and professors at the University of Texas Rio Grande Valley. Experimentalists by training, when they moved to Texas in 2013, a colleague told them that through the University of Texas Research Cyberinfrastructure initiative they […]
