DOAK, G. 0. (University of North Carolina, Chapel Hill), LEON D. FREEDMAN, AND JOHN W. CLARK, JR. Ionic requirements of Treponema pallidum. III. Divalent ions. J. Bacteriol. 82:909912. 1961.-Suspensions of Treponema pallidum, prepared by extracting the testes of syphilitic rabbits with normal rabbit serum or with a culture medium, were shaken with Amberlite IRC-50 resin in the sodium ion form. ...

We report the quantification of partial ion insertion into individual 7,7,8,8-tetracyanoquinodimethane nanoparticles. It is shown that both potassium and sodium ions can be inserted into single TCNQ nanoparticles from aqueous solution. The extent of both potassium and sodium insertion into individual nanoparticles is quantitatively measured and shown to be partial and sodium ion shows a higher ...

To follow up on the performance of lithium-ion batteries (LIBs), transition metal sulfides (TMSs) have been developed as promising carbon alternatives for sodium-ion (SIBs). Although attractive, it is still a great challenge to fulfill their capacity utilization with high cycling performance. Herein, nanoemulsion-directed method has control spherical arrangement [email protected] units both pen...

The Jokoo-ION 150 AC is an automatic sodium, potassium and chloride analyser which uses ion-selective electrodes.The sample mode can be whole-blood, serum or urine. To evaluate a urine sample, a previous dilution (1:6) with the standard 1 solution is required. For three concentrations of control materials, the total precision (CV) ranged from 0.17 to 1.22% for sodium, 0.22 to 1.69% for potassiu...

Passive and active carrier-mediated transport of sodium across vascular muscle membranes has been suggested to be more important in the increased total peripheral resistance found in genetic hypertension. Using manipulations of ion gradients and recordings of ion currents, membrane potentials, and tension, I have found evidence for calcium regulation as the central pathophysiological mechanism ...

A NiS/C sodium-ion battery anode is synthesized from a MOF based on naturally occurring, non-toxic gallic acid.

Understanding dehydration of Prussian white systems to enable processability water-based electrodes for sustainable and high capacity sodium-ion batteries.
