A Nanomechanical Approach for Stretching Microfabricated Diamonds

Diamond is the hardest material in nature. But out of many expectations, it also has great potential as an excellent electronic material. A joint research team led by City University of Hong Kong (CityU) has demonstrated for the first time the large, uniform tensile elastic straining of microfabricated diamond arrays through the nanomechanical approach.

Scientists Study the Effect of Nanoparticles on Oil Production Efficiency

A team of scientists from Siberian Federal University together with their colleagues from Novosibirsk studied the effect of nanoparticles on oil production efficiency. When added to the water that displaces oil from a reservoir, nanoparticles improve the separation of oil drops from mine rock and their washing to the surface. The work received a grant from the Russian Science Foundation, and an article about it was published in the Journal of Molecular Liquids.
