Sodium-ion batteries have attracted considerable interest as an alternative to lithium-ion batteries for electric storage applications because of the low cost and natural abundance of sodium resources. The materials with an open framework are highly desired for Na-ion insertion/extraction. Here we report on the first visualization of the sodium-ion diffusion path in Na3[Ti2P2O10F] through high-...

Soil salinity represents an increasing threat to agricultural production. High sodium (Na) concentrations in soils are toxic to most higher plants. More than 40% of irrigated lands worldwide show increased salt levels. Several studies have shown that under saline conditions, Na influx into root cells occurs via Na permeable transporters (Amtmann et al., 1997; Roberts and Tester, 1997; Tyerman e...

KEY POINTS Body Na+ content is tightly controlled by regulated urinary Na+ excretion. The intrarenal mechanisms mediating adaptation to variations in dietary Na+ intake are incompletely characterized. We confirmed and expanded observations in mice that variations in dietary Na+ intake do not alter the glomerular filtration rate but alter the total and cell-surface expression of major Na+ transp...

Owing to almost unmatched volumetric energy density, Li-ion batteries have dominated the portable electronics industry and solid state electrochemical literature for the past 20 years. Not only will that continue, but they ar...

In some central neurons, including cerebellar Purkinje neurons and subthalamic nucleus (STN) neurons, TTX-sensitive sodium channels show unusual gating behavior whereby some channels open transiently during recovery from inactivation. This "resurgent" sodium current is effectively activated immediately after action potential-like waveforms. Earlier work using Purkinje neurons suggested that the...

N-sodium acrylate-O-carboxymethyl chitosan [CMCH-g-PAA(Na)] bound Fe3O4 nanoparticles were developed as a novel magnetic nanoparticles with an ionic structure that can be potentially used in many fields. CMCH-g-PAA (Na) was obtained by grafting of sodium polyacrylate on O-carboxymethyl chitosan, which is an amphiphilic polyelectrolyte with the biocompatibility and biodegra...

(Na+/K+)ATPase liposomes of various degrees of reconst i tu t ion are formed by varying the amount of phosphatidylcholine added to the soluble (Na+/K+) ATPase before vesicles are formed by cholate removal. In the presence of ATP) the reconstituted sodium pump effectuates (Na+/K +) antiport. In the absence of ATP, the reconstituted sodium pump forms a (Na+/K +) channel. The stable plateaus forme...

Axonal degeneration contributes to the development of non-remitting neurological deficits and disability in multiple sclerosis, but the molecular mechanisms that underlie axonal loss in multiple sclerosis are not clearly understood. Studies of white matter axonal injury have demonstrated that voltage-gated sodium channels can provide a route for sodium influx into axons that triggers reverse op...

Hypoxia reduces alveolar liquid clearance and the nasal potential difference, a marker of airway epithelial sodium transport. The mechanisms underlying this impaired epithelial sodium transport in vivo remain uncertain. We hypothesized that epithelial sodium transport impaired by hypoxia would recover quickly with reoxygenation and that hypoxia decreases the expression of lung epithelial sodium...
