• Scientists enhance durability of lithium-sulfur batteries with dyes
  

  Many emerging technologies related to sustainable energy, such as grid-scale energy storage systems and electric cars, require high-performance rechargeable batteries. Unfortunately, conventional lithium-ion batteries (LIBs) have almost reached their theoretical limit, and need to be supplanted by b more

• Harvard researchers use dyes to store data
  

  In the digital age, every byte of data needs to go somewhere — and preferably stay there a long time. That last part is a major problem when it comes to data-storage systems, which typically last less than 20 years. A group of Harvard chemists is trying to solve the issue with an innovation that res more

• Switched on IR-Active Organic Pigments
  

  In photosynthesis and organic photovoltaics, pigment molecules convert light into electrical charge. A team of chemists have now produced an unusual organic pigment, which is “switched on” by an electrical charge to become a potent dye that absorbs light in the near-infrared range. The team's study, more

The Chemistry of Highlighter Colours

If you’re currently a student, then you’ll no doubt often make ample use of highlighters during revision. Even if your studying days are far behind, you probably still use them from time to time. But what are the chemicals behind their luminous colours? This graphic looks at some of the possible dye more

The Chemistry of Glow Sticks

Everyone’s familiar with glow sticks, but it’s likely that fewer are familiar with the chemistry behind their glow. You may have wondered what happens when you snap a glow stick to activate it; by doing this, you’re actually kicking off a chemical process that eventually leads to the production of t more

The Key Chemicals in Red Wine

Red wine has been espoused over the years for its supposed health benefits, from claims that it could let us live to 150, to assertions that chemicals within it can help prevent cancer. Whilst these are no doubt a very pleasant means to justify a glass of wine (or several), how correct are they? Sim more

• A simple and versatile strategy for realizing bright multicolor mechanoluminescence

  Multicolor mechanoluminescence(ML) is first realized by using the stable organic blue ML emitter N-henylcarbazole as host matrix. It is claimed that a good ML host should have a moderate melting point and can dissolve or disperse organic dyes but maintain high ML activity and crystallinity. This str more

  A bifunctional cationic metal–organic framework {[Cu9(OH)6Cl2(itp)6(1,4-bdc)3](NO3)2(OH)2·20H2O}n (1-NO3-OH·20H2O) was synthesized and characterized (itp = 1-imidazol-1-yl-3-(1,2,4-triazol-4-yl)propane, 1,4-bdc = 1,4-benzenedicarboxylate). In 1-NO3-OH·20H2O, three [Cu3(μ3-OH)(μ2-OH)] trimeric cluste more
