Changes in Resting Potential Due to a Shift of Electrolytes in the Cell Produced by Non-electrolytes
Experiments on Nitella indicate that the resting potential is due chiefly to the outwardly directed diffusion potential of electrolytes which is set up at the inner, non-aqueous, protoplasmic surface surrounding the vacuole. We might therefore expect that any change in the concentration of these electrolytes would affect the resting potential. The experiments described here indicate that this e...
The effect of -Al2O3 particles on the electrochemical codeposition behaviour of Co–Ni alloys from sulfamate electrolyte was investigated by codeposition experiments, zeta potential and electrochemical methods. The results indicate that the presence of Al2O3 particles in Co–Ni sulfamate electrolytes contributes to the preferential codeposition of Co. Moreover, increasing Co2+ concentration also ...
Magnetite-ENR polymer electrolytes doped with various % wt of LiCF3SO3 salt were synthesized in-situ in the presence of ENR and cast into film doped with LiCF3SO3. XRD results confirmed the purity of the as-formed magnetite particles. The diffraction peaks assigned for LiCF3SO3 become more intense as the concentration of salt is increased. FTIR analyses showed that both “free” (dissociation) an...
Concepts of the modified and the excess Walden products are introduced and discussed when applied together with the ordinary Walden product. The existence of the universal curves of limiting conductances for electrolytes (or for ions) in a given pair of solvents are further examined for a number of mixtures which include ethanol, 2-propanol, 1,1,1,3,3,3hexafluoro-2-propanol, N,N,-dimethylformam...
Blood viscosity is a crucial hemodynamic biomarker because it determines the friction against blood vessels, the quantity of oxygen that is delivered to organs and tissues, and the degree of exertion by the heart. Many factors affect blood viscosity, either directly or inversely. e.g., fibrinogen and hematocrit. The effect of other factors (e.g., cholesterol) on blood viscosity is still under i...
The oligo(ethylene oxide) modified layered double hydroxide (LDH) prepared by template method was added as a nanoscale nucleating agent into poly(ethylene oxide) (PEO) to form PEO/OLDH nanocomposite electrolytes. The effects of OLDH addition on morphology and conductivities of nanocomposite electrolytes were studied using wide-angle X-ray diffractometer, polarized optical microscopy, differenti...
In this study, promising electrolytes for use in Li-ion batteries are studied in terms of interacting and wetting polyethylene (PE) and particle-coated PE separators. The electrolytes are characterized according to their physicochemical properties, where the flow characteristics and the surface tension are of particular interest for electrolyte-separator interactions. The viscosity of the elect...
INTRODUCTION The aim of the study was to evaluate stability of 48 total parenteral admixtures for pediatric patients who require home parenteral nutrition. Admixtures contain high amounts of electrolytes. In a clinical practice electrolytes-enrichment of the parenteral nutrition admixtures is a usual demand, especially on the neonatal/pediatric wards. The supplementation of parenteral nutrition...
45 (continued on next page) Lithium batteries use organic electrolytes because of the wide operating voltage. For lithium ion rechargeable batteries, these electrolytes are almost universally based on combinations of linear and cyclic alkyl carbonates. These electrolytes make possible the use of Li as the anodic active component and results in the high power and energy densities characteristic ...
S are a unique type of high-power electrochemical energy storage devices being developed for a wide range of applications, including consumer electronics, medical electronics, electrical utilities, transportation, and military defense systems. However, the energy and power densities, safety, and cycle life of currently available supercapacitors need to be significantly improved to satisfy the r...
