Chemistry controls magnetism
Mon, 12 Oct 2015 12:28:53 EDT
Magnets are well-known from the physics lessons at school, but they are hardly covered in chemistry lectures; and it is still a chemical process by means of which researchers have succeeded in controlling magnetic properties in bulk ferromagnets. While physical processes may influence the orientation of the magnetic fields, the chemical process in this case controls magnetism in carefully chosen strongly ferromagnetic material systems. The working principle used in this case is similar to the concept of lithium-ion batteries.
Establishment of systems metabolic engineering strategies to develop microbial strains

Ten general strategies of systems metabolic engineering have been proposed by experts to successfully develop industrial microbial strains.
'Nanohoops' could energize future devices

When scientists began making tiny organic circular structures using carbon atoms, the idea was to improve carbon nanotubes for use in electronics or optical devices. Now they believe this technique might roll solo. Researchers now show that these cycloparaphenylenes can be made using a variety of atoms, not just those from carbon.
Single atom alloy platinum-copper catalysts cut costs, boost green technology
Fri, 09 Oct 2015 10:20:32 EDT
A new generation of platinum-copper catalysts requiring very low concentrations of platinum in the form of individual atoms to cleanly and cheaply perform important chemical reactions is reported. The new catalysts could also facilitate broader adoption of environmentally friendly devices and processes.
Faster design, better catalysts

While the cleaning of car exhausts is among the best known applications of catalytic processes, it is only the tip of the iceberg. Practically the entire chemical industry relies on catalytic reactions. Therefore, catalyst design plays a key role in improving these processes. An international team of scientists has now developed a concept, that elegantly correlates geometric and adsorption properties. They validated their approach by designing a new platinum-based catalyst for fuel cell applications.
