The irreversible oxygen redox and structural degradation of LiNi 0.8 Co 0.1 Mn O 2 (NCM811) at a 4.5 V high voltage cause severe decline in cycling performance for lithium‐ion batteries. In this study, novel approach is proposed to enhance the anionic chemistry stability NCM811 cathode material by introducing gaseous selenium. Se β+ species are selectively adsorbed within vacancies, leading con...

Reflections, electric field and dissipated power of a 915 MHz water load produced by The Ferrite Company, Inc. are computed by QuickWave-3D for water temperatures from 5 to 60∞C. A simple empirical model generalizing experimental data is used for calculating the dielectric constant of fresh tap water at 915 MHz and for different temperatures. The computer model is verified by measurement of ref...

An extremely haloalkaliphilic archaeon Natrinema sp. SSBJUP-1 showing potent amylolytic and proteolytic activities was isolated from the saline alkaline Lonar Lake, India. Amylase and protease were active over the neutral to alkaline pH range from 6 to 9. Amylase was more stable over a narrower temperature range of 40-60C than the protease but had the higher optimum (55C) for activity. By contr...
