Layered chambers open a window for drug release 

Implantable arrays of microchambers show potential capacity for holding and releasing precisely controlled quantities of drugs on command, report A*STAR researchers with colleagues in Singapore, Russia and the United Kingdom.

Deformation of nanotubes to control conductivity

Scientists from the NUST MISIS Laboratory of Inorganic Nanomaterials and international colleagues have proved that it's possible to change the structural and conductive properties of nanotubes by stretching them. This finding ...

Graphene's effects on the lungs

Graphene has been hailed as the material of the future. As yet, however, little is known about whether and how graphene affects our health if it gets into the body. A team of researchers from Empa and the Adolphe Merkle Institute ...

Placing atoms for optimum catalysts

Fuels, plastics, and other products are made using catalysts, materials that drive chemical reactions. To design a better catalyst, scientists must get the right atoms in the right spot. Positioning the atoms can be difficult, ...
