Transformation of a Silicate Material for Carbon Negative Magnesia‐Based Cement via Electrochemistry
Advanced Science, EarlyView.The transformation of a magnesium trisilicate material via water electrolysis into precursor phases necessary for magnesium‐based M‐S‐H cement is explored. The dissolution of the material mediated electrochemically is monitored, and the analysis of the resulting phases indicate their suitability as effective precursors for M‐S‐H cement.

Secular Stagnation and Decline: A Simplified Model [PDF]
SSRN Electronic Journal, 2014 Presented is a mathematical model of single-product economy describing a nominal economic growth and a nominal economic decline. Based on the model of economic dynamics, policies handling the gravity of the secular stagnation are furnished. First, transition of the secular stagnation into the secular decline is to be prevented.

Therapeutic Repair of Sperm Quality Decline Caused by Polytetrafluoroethylene
Advanced Science, EarlyView.Exposure to PTFE (teflon), a commonly used microplastic in non‐stick cookware, significantly reduces sperm quality in both humans and mice. Specifically, PTFE induces the disruption of sperm cytoskeleton and F‐actin assembly through targeting SKAP2 in haploid spermatid.

Advanced Science, EarlyView.The in situ evolution of single‐atom catalysts to metallic nanoclusters during nitrate electroreduction is demonstrated. A direct correlation between the OH binding energy on the metallic clusters and ammonia production rate is established as a key activity descriptor, explaining the superior performance of Ni and Co catalysts.
