(Cr1−xAlx)N Coating Deposition by Short-Pulse High-Power Dual Magnetron Sputtering » The paper deals with the (Cr[1−x] Al[x] )N coating containing 17 to 54 % Al which is deposited on AISI 430 stainless steel stationary substrates by short-pulse high-power dual magnetron sputtering of Al and Cr targets. The Al/Cr ratio in the coating… Ncbi.nlm.nih.gov

Water Increases the Faradaic Selectivity of Li-Mediated Nitrogen Reduction » The lithium-mediated system catalyzes nitrogen to ammonia under ambient conditions. Herein we discover that trace amount of water as an electrolyte additive─in contrast to prior reports from the literature–can effect a dramatic improvement in the Faradaic selectivity of N2 reduction to NH3. We report that an optimal water concentration of 35.9 mM and LiClO4 salt concentration of 0.8 M allows a Faradaic efficiency up to 27.9 ± 2.5% at ambient pressure. We attribute the increase in Faradaic efficiency to the incorporation of Li2O in the solid electrolyte interphase, as suggested by our X-ray photoelectron spectroscopy measurements. Our results highlight the extreme sensitivity of lithium-mediated N2 reduction to small changes in the experimental conditions. Pubs.acs.org

First U.S. execution by nitrogen gas would cause "painful and humiliating death," U.N. experts warn » Experts have denounced Alabama's planned execution of a death row inmate by nitrogen hypoxia — an untested suffocation method that they say could cause "grave suffering." Cbsnews.com

Assessment of energy expenditure: are calories measured differently for different diets? » The prevalence and burden of obesity has reached alarming levels. The assessment of human energy expenditure enables the identification of obesity-prone and obesity-resistant individuals and helps to explain the short and long-term success of weight loss… Ncbi.nlm.nih.gov
