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...

in the present study, five modeling approaches of ra, mlp, mnn, gff, and canfis were applied so as to estimate the radial overcut values in electrochemical drilling process. for these models, four input variables, namely electrolyte concentration, voltage, initial machining gap, and tool feed rate, were selected. the developed models were evaluated in terms of their prediction capability with m...

Electrostatic stabilization is reduced in its efficiency in an electrolyte-containing environment. The effect of electrolyte concentration is mostly described as negative factor for dispersion stabilization. Usually, zeta potential and physical stability decrease at increasing electrolyte concentration. The purpose of the present study was to measure the surface properties of nanotubes in aqueo...

Diffusioosmosis of an electrolyte solution is the electrokinetic flow involving a tangential concentration gradient of the electrolyte that interacts with a charged wall. Electrolyte solutions with a concentration gradient of order 1 M/cm along solid surfaces with a zeta potential of order kT/e (~25 mV; e is the charge of a proton, k is the Boltzmann constant, and T is the absolute temperature)...

Interaction of polyadenylic acid, poly(A), with stearic acid Langmuir-Blodgett (LB) monolayer was studied in different electrolyte surroundings. For this purpose LB films of stearic acid, transferred on the mica substrate from poly(A) containing subphase, were analyzed with atomic force microscopy (AFM). The density of polynucleotides surface coverage is ruled by the monovalent electrolyte conc...

Co-Fe films were electrodeposited on Cu substrate from electrolytes with different Co concentration  levels. X-ray diffraction (XRD) was used  to  investigate  the  films  crystal  structures. The  results  indicate that  if  the  Co  concentration  is  less  that  the  Fe  concentration,  the cubic  structure  appears  in  the  films, while  the  hexagonal  structure dominates when  the C...

The main objective of this study is removal of pathogenic bacteria using electrochemical process. The bactericidal effects of electrochemical system containing steel mesh electrode were evaluated from contaminated water with E. coli, Pseudomonas aeroginosa, Staphylococcus aureous and Streptococcus fecalis at various concentrations. Effect of current density, supporting electrolyte and pathogeni...

The pH of TEMPOL electrolyte greatly affects the reversibility of its redox reaction. Reaction of TEMPOL with OH ion causes the decrease of electrolyte pH. TEMPOL in an acidic electrolyte leads to a decrease in its concentration. a r t i c l e i n f o
