Biophysics and Biophysical Chemistry Series

PCCP is delighted to announce a high-profile series of themed issues in the fields of biophysics and biophysical chemistry to highlight some of the great content we publish in this area.

The series contains issues on a variety of topics in this exciting multidisciplinary research area.

biophysicalTake a look at the great issues today:

This high-profile series is Guest Edited by PCCP Advisory Board member Seong Keun Kim (Seoul National University, Korea), Jean-Pierre Schermann (Université Paris 13, France), and Taekjip Ha (University of Illinois, USA). The series also contains an issue on molecular mechanisms of the photostability of life Guest Edited by Andrzej Sobolewski and Wolfgang Domcke.

We believe that this series of themed issues will serve to foster links between the biophysics and biophysical chemistry research communities and will have a valuable and lasting impact in this research field.

Gold improves photovoltaic cell efficiency

Teams from India, the US and Thailand have studied the mechanism of the catalytic activity of gold nanoparticles in semiconducting zinc oxide/gold nanocomposites used in photocatalysis and dye-sensitised solar cells.

The study was carried out to better understand the charge-transfer process at the semiconductor/metal interface to optimise the catalysts’ performance.

The team found that the gold nanocomposites improve the energy conversion efficiency of the solar cells compared to zinc oxide nanoparticles.
