in present study, molecular dynamics simulation of cadmium (ii), lead (ii) and copper (ii) removal from aqueous electrolyte solutions using the ion-exchange process with the zeolite particles was done. the results showed that, most of the particles had the highest affinity of ion exchanging with lead (ii) and the lowest affinity with copper (ii). the calculated mean ion-exchange ratios showed t...

in this work, a tracer study on pore initiation in anodic alumina in oxalic acid was performed. effects of some experimental parameters such as applied electrical potential, electrolyte composition and heat pretreatment were evaluated. electrochemical and morphological experiments were performed using potentiostatic anodizing and scanning electron microscopy (sem) techniques, respectively. effe...

Glomerular filtration rate (GFR), renal plasma flow (RPF), and electrolyte excretion were studied in 17 patients subjected to salt depletion and loading. Salt depletion led to maximal renal salt conservation with the average GFR and RPF slightly decreased. Salt loading produced increased excretion of sodium and chloride with the average GFR and RPF slightly increased. Since the decreased electr...

In a heterogeneous electrolyte system of a strongly basic anion exchanger and solutions of NaBF4 or NaClC>4 we established the influence of the nature and concentration of the eluent in chromatographic experiments on chlorine isotope separation. Results show that when the electrolyte concentration is increased the degree of isotope separation decreases. With NaBF4 the separation factor is great...

Disturbances of acid-base balance and electrolyte abnormalities are commonly seen in patients with acute leukemia. Our study aimed at illuminating the probable pathogenetic mechanisms responsible for these disturbances in patients with acute leukemia admitted to our hospital. We studied 66 patients (24 men and 44 women) aged between 17 and 87 years old on their admission and prior to any therap...

We have directly observed the structural evolution of colloidal crystals as a function of increasing ionic strength using confocal scanning laser microscopy. Silica colloids were sedimented onto a glass substrate in deionized water to create large, single domain crystals. The solution ionic strength was then increased by one of three methods of controlled electrolyte addition: (1) direct inject...

We demonstrate the formation of charged molecular packets and their transport within optically created electrical force-field traps in a pH-buffered electrolyte. We call this process photoelectrophoretic localization and transport (PELT). The electrolyte is in contact with a photoconductive semiconductor electrode and a counterelectrode that are connected through an external circuit. A light be...

Recent advances in power generation from renewable resources necessitate conversion of electricity to chemicals and fuels in an efficient manner. Electrocatalytic water splitting is one of the most powerful and widespread technologies. The development of highly efficient, inexpensive, flexible, and versatile water electrolysis devices is desired. This review discusses the significance and impac...
