New research suggests that hand sanitizers containing ethanol are much more effective at removing rhinovirus from hands than washing with soap and water.

A new study suggests that hand sanitizers containing ethanol are much more effective at removing rhinovirus from hands than washing with soap and water. Sanitizers containing both ethanol and organic acids significantly reduced recovery of the virus from hands and rhinovirus infection up to 4 hours following application.

Nanotechnology Sparks Energy Storage on Paper and Cloth

100220204808

Recipe for conductive textile: Dip cloth in nanotube ink, dry in oven for 10 minutes at 120 degrees Celsius.

By dipping ordinary paper or fabric in a special ink infused with nanoparticles, Stanford engineer Yi Cui has found a way to cheaply and efficiently manufacture lightweight paper batteries and supercapacitors (which, like batteries, store energy, but by electrostatic rather than chemical means), as well as stretchable, conductive textiles known as “eTextiles” — capable of storing energy while retaining the mechanical properties of ordinary paper or fabric.

This image shows the process by which Photosystem I in thermophilic blue-green algae can be catalyzed by platinum to produce a sustainable source of hydrogen.

In the quest to make hydrogen as a clean alternative fuel source, researchers have been stymied about how to create usable hydrogen that is clean and sustainable without relying on an intensive, high-energy process that outweighs the benefits of not using petroleum to power vehicles.
