The hidden side of sulfur


Synthetic organic chemistry consists of transforming existing molecules into new molecular structures or assemblies. These new molecular systems are then used in a myriad of ways in everyday life - in a wide range of sectors, such as public health, energy and environment, for use in drugs, solar ...

A Negative Enzyme Yields Positive Results


Chemistry has provided many key tools and techniques to the biological community in the last twenty years. We can now make proteins that Mother Nature never thought of, image unique parts of live cells and even see cells in live animals. This week in ACS Central Science, two research groups from ...

Superconductivity seen in a new light


Superconducting materials have the characteristic of letting an electric current flow without resistance. The study of superconductors with a high critical temperature discovered in the 1980s remains a very attractive research subject for physicists. Indeed, many experimental observations still ...

An infallible quantum measurement


For quantum physicists, entangling quantum systems is one of their every day tools. Entanglement is a key resource for upcoming quantum computers and simulators. Now, physicists in Innsbruck/Austria and Geneva/Switzerland realized a new, reliable method to verify entanglement in the laboratory ...


Single enantiomer using copper catalyst


Chemists in Switzerland show that a racemic mixture can be transformed into one enantiomer, using a copper catalyst. The concept of the dynamic kinetic asymmetric transformation in allylic substitutions represents an efficient methodology for transforming a racemic mixture into one ...

New synthetic route to oxindoles


Peter Kündig and colleagues from Geneva University, Switzerland and Stephen Marsden and co-workers at the University of Leeds, in the UK, have developed an asymmetric Pd/N-heterocyclic carbene (NHC) - catalysed intramolecular -arylation of amide enolates, containing heteroatom sustituents. This ...
