Storing energy harvested by triboelectric nanogenerators (TENGs) from ambient mechanical motion is still a great challenge for achieving low-cost and environmental benign power sources. Here, an all-solid-state Na-ion battery with safe and durable performance used for efficient storing pulsed energy harvested by the TENG is demonstrated. The solid-state sodium-ion batteries are charged by galva...

A number of advances have been made recently in our knowledge of the mechanisms of mitochondrial Ca2+ transport, and these offer new perspectives to the problem of why mitochondria transport Cal+. Progress with cardiac mitochondria has been favoured by the resolution of the overall flux of Caz+ across the inner membrane into two distinct components, which represent catalysis by two separate car...

Native sodium and potassium adenosine triphosphatase from guinea pig kidney accepted a phosphate group from radioactive inorganic phosphate to form an acyl phosphate bond at the active site in the presence or absence of sodium ion. Magnesium ion was always required. In the presence of sodium ion and absence of adenosine triphosphate, there was no phosphorylation by inorganic phosphate. Addition...

The protonation constant values of salicylic and 5-nitrosalicylic acid werestudied by a combinationof spectrophotometric and potentiometric methods at 25 °C in wide range of ionic strength. The ionicstrength of solutions was kept constant by sodium perchlorate as background electrolyte at 0.10 to 3.0 moldm-3. Potentiometer was calibrated according to Gran method at each of ionic strength. The p...

Fatty acids are long-chain carboxylic acids that readily produce [M - H](-) ions upon negative ion electrospray ionization (ESI) and cationic complexes with alkali, alkaline earth, and transition metals in positive ion ESI. In contrast, only one anionic monomeric fatty acid-metal ion complex has been reported in the literature, namely [M - 2H  +  Fe(II)Cl](-). In this manuscript, we present two...

The paper reports the performance of a nanostructured InSb alloy as promising negative electrode for sodium-ion batteries.

UNLABELLED The model of sodium and chloride transport proposed for the colon is based on studies performed in the distal segment and tacitly assumes that ion transport is similar throughout the colon. In rat distal colon, neutral sodium-chloride absorption accounts for the major fraction of overall sodium absorption and aldosterone stimulates electrogenic, amiloride-sensitive sodium absorption....

Subsequent purification studies showed that the sodium channel from mammalian brain is a complex of ␣ al., 1982), the tetrodotoxin-binding component of the sodium channel purified from eel electroplax is a single Voltage-gated sodium channels are responsible for the protein of 270 kDa (Miller et al., 1983), and the ...

Sodium-ion batteries have potential as energy-storage devices owing to an abundant source with low cost. However, most electrode materials still suffer from poor conductivity, sluggish kinetics, and huge volume variation. It is challenging explore apt for sodium-ion battery applications avoid the pulverization of electrodes induced by reversible intercalation large sodium ions. Herein, we repor...
