Flexible Cellulose Nanogenerators Could Potentially Power Biomedical Devices Inside the Body

Implantable electronics that can deliver drugs, monitor vital signs and perform other health-related roles are on the horizon. But finding a way to power them remains a challenge. Now scientists have built a flexible nanogenerator out of cellulose, an abundant natural material, that could potentially harvest energy from the body -- its heartbeats, blood flow and other almost imperceptible but constant movements. Their report appears in the journal ACS Applied Materials & Interfaces.

Iron-Nitrogen Complexes in Graphene Could Substitute Platinum-Based Catalysts

Teams at HZB and TU Darmstadt have produced a cost-effective catalyst material for fuel cells using a new preparation process which they analysed in detail. It consists of iron-nitrogen complexes embedded in tiny islands of graphene only a few nanometres in diameter. It is only the FeN4 centres that provide the excellent catalytic efficiency – approaching that of platinum. The results are interesting for solar fuels research as well and have been published in the Journal of the American Chemical Society.

Researchers Demonstrate First Ever Measurement of Electron Temperatures in Nanoelectronic Device

The first ever measurement of the temperature of electrons in a nanoelectronic device a few thousandths of a degree above absolute zero was demonstrated in a joint research project performed by VTT Technical Research Centre of Finland Ltd, Lancaster University, and Aivon Ltd. The team managed to make the electrons in a circuit on a silicon chip colder than had previously been achieved.

Fullerene Stereomer Could Influence Photovoltaic Performance

Organic/polymer solar cells represent the most important direction for green energy in the future. Fullerene electron acceptors have been widely used in organic/polymer solar cells as well as perovskite solar cells. A recent study reveals that the photovoltaic performance can be influenced by fullerene stereomer, implies that the stereomeric effect should be envisaged if new fullerene derivative was designed as electron acceptor.
