Keeping It In Balance

Guest Post by Willis Eschenbach A short post. I came into my obsession with the climate by a side door. Back around the turn of the century, I read that the global average surface temperature was in danger of going through the roof because of increasing CO2. But when I got to thinking about it,…

The Honest Story of Climate Change: Part I: Weighed down by fear and intimidation.

By Guus Berkhout & Kees de Lange There is no climate crisis, even if politicians, climate institutes, and the media would have you believe there is. Climate change is a fact, but it is a change as in everything changes, both inside and outside our atmosphere. No surprise! We will show that we should not…

"Developing high-power Li||S batteries via transition metal/carbon nano" by Huan Li, Rongwei Meng et al.

The activity of electrocatalysts for the sulfur reduction reaction (SRR) can be represented using volcano plots, which describe specific thermodynamic trends. However, a kinetic trend that describes the SRR at high current rates is not yet available, limiting our understanding of kinetics variations and hindering the development of high-power Li||S batteries. Here, using Le Chatelier’s principle as a guideline, we establish an SRR kinetic trend that correlates polysulfide concentrations with kinetic currents. Synchrotron X-ray adsorption spectroscopy measurements and molecular orbital computations reveal the role of orbital occupancy in transition metal-based catalysts in determining polysulfide concentrations and thus SRR kinetic predictions. Using the kinetic trend, we design a nanocomposite electrocatalyst that comprises a carbon material and CoZn clusters. When the electrocatalyst is used in a sulfur-based positive electrode (5 mg cm−2 of S loading), the corresponding Li||S coi
