Graphene Nanoribbons Promise to Improve LI Batteries
19 June 2013POSTED IN Research
Researchers at Rice University, Houston, Texas (US), have created a process for splitting carbon nanotubes into graphene nanoribbons (GNRs) that, in a solution with tin oxide, could be used to improve the performance of lithium ion (LI) batteries. Proof-of-concept anodes built with these single-atom-thick GNRs demonstrated a better capacity than tin oxide alone. In fact, the scientists say the method can more than double the capacity and increase cyclability from only one cycle to many hundreds of cycles.

Nanostructure-Coated Black Silicon Solar Cells Via ALD
09 May 2013POSTED IN Research
Aspiring to improve photovoltaic energy conversion efficiency by using latest advances in nanotechnology, researchers at Aalto University, Finland, are combining “black silicon” with the method of atomic layer deposition (ALD). As a result, the nanostructures fabricated by plasma dry etching minimise sunlight reflection. Moreover, a conformal, thin passivating layer, deposited onto the nanostructures through ALD, prevents charge carriers from recombining at the surface.
