This paper presents efflux time experiments performed in the absence and presence of aqueous solutions of Drag Reducing Agents (DRAs) when a liquid is emptied from a large open cylindrical storage tank through an exit piping system. The drag reducing agents studied are Dodecyl benzene sulfonate anionic surfactant and a mixed solution of surfactant and sodium chloride counter ion. The variab...

In this study, polystyrene ethylene butylene polystyrene (PSEBS) was functionalized to prepare mono and bipolar ion exchange membranes. In the case of the bipolar membrane, platinum was used as the intermediate layer. NaCl solution of concentration ranging from 5 g/L to 25 g/L was used as the feed solution. A commercially procured ion exchange membrane made of polystyrene divinyl benzene was al...

Abnormalities in the human Nav1.5 (hNav1.5) voltage-gated sodium ion channel (VGSC) are associated with a wide range of cardiac problems and diseases in humans. Current structural models of hNav1.5 are still far from complete and, consequently, their ability to study atomistic interactions of this channel is very limited. Here, we report a comprehensive atomistic model of the hNav1.5 ion channe...

In this study, the adsorption of thallium (III) ion from aqueous solutions onto modified ZnOnanopowder as a fairly low cost adsorbent has been investigated in batch mode. It was found thatmodification of the adsorbent was essential for obtaining the significant adsorption percentage. Theadsorbent modified by sodium phosphate solution. The effect of experimental parameters such asinitial pH of s...

Molybdenum-based materials exhibit a high capacity and rich reaction chemistry for sodium, but their potential in sodium-ion batteries has been plagued by several technical challenges. In this review, the authors present state-of-the-art overview of research progress molybdenum-based sodium storage, highlight engineering strategies that are capable addressing these challenges, offer valuable in...

The Front Cover shows sodium ions intercalating into a bunch of flexible & freestanding hard carbon, emphasizing the environmental sustainability recycling cotton textiles to produce free-standing carbon anodes for sodium-ion batteries. More information can be found in Research Article by H. R. Sarma et al.

The effects of monovalent cations on the active calcium-accumulating ability of cardiac sarcoplasmic reticulum were assessed. Grana prepared in an ion-free system accumulated calcium when ATP and Mg(++) were present. Sodium ion and to a lesser extent lithium but not K(+) reduced the amount of calcium taken up. The reduction of calcium binding by Na(+) is not due to inhibition of uptake but to a...

We use inelastic neutron scattering and molecular dynamics simulation to investigate the interplay between the structure and the fast sodium ion diffusion in various sodium silicates. With increasing temperature and decreasing density the structure factors exhibit an emerging prepeak around 0.9 A(-1). We show that this prepeak has its origin in the formation of sodium rich channels in the stati...

The potentially high gravimetric capacities of intermetallic anodes, coupled with the low cost and readily available materials used in sodium-ion batteries, has generated interest in antimony—an anode capable of alloying with sodium. However, presently there are few synthetic routes to antimony particles for use in sodium-ion batteries. One pot, sol-gel synthetic routes from readily available, ...

Structural imperfections, heteroatom dopants, and the interconnected pore structure of carbon materials have a huge impact on their electrochemical performance in lithium-ion sodium-ion batteries due to specific ion transport dominant storage mechanism at surface defect sites. In this work, mesopore-enriched nitrogen-doped (NC) were produced with template-assisted chemical vapor deposition usin...
