The modulation of the ion-fluxes across a polymeric membrane is important for designing attractive methodologies. As an alternative to commonly used dynamic electrochemistry approaches, light can be as external stimulus and provides very convenient way manipulate ions release and/or extraction into membrane. Herein, we designed solid-contact ion-selective sensor that exhibits response by irradi...
a systematic study on the electrochemical behavior of the s-derivatives of 2-amino cyclopentene-1-dithiocarboxylic acid (acda) has been carried out in aqueous ethanolic solutions by means of polarography, coulometry and voltammetry. all the compounds studied exhibited a well defined anodic wave corresponding to a diffusion controlled process. controlled potential coulometry gave n=1 per mole fo...
Acid-base titrations can be carried out successfully in the solvent ??Icresol’. This is important for the determination of the acid or base content of some polymers for which ~cresol is a good solvent. The study of acid-base coulometry in nr-cresol was started because of the several advantages offered by coulometry: greater sensitivity, no problems with unstable titrants, and no need for standa...
in this thesis, structural, electronical, and optical properties of inverse pervskite(ca3pbo) in cubic phase have been investigated.the calculation have been done based on density functional theory and according to generalized gradiant approximate (gga) as correlating potential. in order to calculate the configurations, implementing in the wien2k code have been used from 2013 version. first of ...
Not only are the quantities of emerging precision cleaning agents, equipment, and processes staggering, but assessing their level of performance relative to previous approaches presents even greater challenges. As en vironmentally harmful cleaning solvents are phased out and replaced, the quest for implementing alternative technologies raises numerous questions: l What alternative cleaning agen...
The proposed recommendation for measuring and reporting chloride in undiluted plasma or blood by ion-selective electrodes (ISEs) will provide results that are identical to chloride concentrations measured by coulometry for standardized normal plasma or blood samples. It is applicable to all current ISEs dedicated to chloride measurement in undiluted samples that meet the requirements. However, ...
