Ultrathin Na2Ti2O4(OH)2 nanosheets of ∼8 nm thickness were prepared by a facile method for the first time. The resulting material was also used as a conducting agent and binder-free anode, both for sodium-ion batteries and lithium-ion batteries, for the first time. The Na2Ti2O4(OH)2 nanosheets exhibited excellent Na/Li-ion storage performance. A long-term cycling performance of the ultrathin Na...
Introduction The microbial habitats formed through plant patches, as fertile islands, are an effective factor in the development of vegetation and improve the soil surface characteristics of saline ecosystems. The pulping plant is the most economical solution for improving the saline soils, in this way, toxic ions, especially chlorine and sodium, are removed from the soil by salinity resistant...
Membrane-bound pyrophosphatases (M-PPases), which couple proton/sodium ion transport to pyrophosphate synthesis/hydrolysis, are important in abiotic stress resistance and in the infectivity of protozoan parasites. Here, three M-PPase structures in different catalytic states show that closure of the substrate-binding pocket by helices 5-6 affects helix 13 in the dimer interface and causes helix ...
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...
TO THE EDITOR: In a recent review, O’Brodovich et al. (7) analyzed experimental evidence for the significance of amiloride-insensitive alveolar epithelial sodium transport in the mammalian lung. In a recent observational study of epithelial ion transport in children with meningococcal septicemia-induced pulmonary edema, indirect evidence of a systemic reduction in epithelial sodium transport as...
The deposits of clinoptilolite (CLI) in Iran after activation with sodium chloride or sodium hydroxide solution was subjected to ion exchange with some heavy and toxic cations. The results showed that the absorption for Ca2+ (7.5 ppm), Cu2+ (50 ppm), Zn2+ (40 ppm), Cd2+ (40 ppm), Pb2+ (500 ppm) and Al3+ (5 ppm) were 95.2, 96.70, 93.30,99.12, 99.2 and 90.0 percents, respectively. The noteworth...
The function of G protein-coupled receptors (GPCRs) can be modulated by a number of endogenous allosteric molecules. In this study, we used molecular dynamics, radioligand binding, and thermostability experiments to elucidate the role of the recently discovered sodium ion binding site in the allosteric modulation of the human A(2A) adenosine receptor, conserved among class A GPCRs. While the bi...
Metal sulfides are promising anode materials for sodium-ion batteries (SIBs) because of their high theoretical capacities. However, they usually limited by poor cycling performance and rate properties due to large volume expansion sluggish reaction kinetics. Herein, Sb2S3/SnS2/C heterostructures were fabricated directly growing SnS2 nanoplates on Sb2S3 nanorods then coating surface with a carbo...
