Theoretical research by scientists with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) has led to record-breaking sunlight-to-electricity conversion efficiencies in solar cells. The researchers showed that, contrary to conventional scientific wisdom, the key to boosting solar cell efficiency is not absorbing more photons but emitting more photons.
Nanotechnology researchers at the Georgia Institute of Technology have conducted the first direct comparison of two fundamental techniques that could be used for chemically doping sheets of two-dimensional graphene for the fabrication of devices and interconnects.
A group of researchers from Thailand investigated the combined effect of adsorption and oxidation for phenolic wastewater treatment using a three phase fluidized bed reactor. The group continuously fed aqueous solutions containing phenol and ozone into a reactor resulting in a comparison of seven cases.
Ein flexibles und effizientes neues Verfahren zur Trennung von Enantiomeren haben Forscher des Karlsruher Instituts fuer Technologie (KIT) und der Ruhr-Uni Bochum (RUB) entwickelt. Die Enantiomerentrennung ist unerlaesslich fuer die Herstellung vieler Medikamente.
It has been shown recently that movement of fluid in microfluidic devices can be harnessed and converted into electricity. Researchers have now conducted calculations that suggest this electrokinetic energy conversion could be more efficient than previously thought thanks to the strange properties of fluid flow at the nanometer scale.
