Numerous metalloenzymes make use of their metal centers to promote substrate oxidations in a highly controlled fashion. Chemists have long wondered in this context how much of the reactivity is … [Read more]

A year and a half ago, an article about cycads at the University of Giessen brought to my attention the University’s most famous member, about whom Wikipedia says:
Non-repeating crystals, once thought impossible, can boost thermoelectric conversion and brighten LEDs
Engineers have made an electrochemical cell that uses a plasma for an electrode, instead of solid pieces of metal. The technology may open new pathways for battery and fuel cell design and manufacturing, making hydrogen fuel and synthesizing nanomaterials and polymers.
Biological nanopores are proteins of only a few nanometers in diameter that form tiny water-filled canals. They have proven to be promising tools in the field of nanobiotechnology. Researchers in Germany have succeeded in arranging nanopores on a tiny microchip and using it to determine the mass of chain-like molecules called polymers with a high degree of precision.
(American Institute of Physics) Icy dust specks could provide an interstellar staging ground for chemical reactions that form complex organic molecules.
Topological insulators — insulators or semiconductors with metallic states present at their boundaries — are the 'rising stars' of condensed-matter physics. This Perspective introduces these materials and their properties, and looks at the challenges and opportunities the community faces.
