abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
The decline in religious identification and corresponding increase in the unaffiliated has been one of the most important religious changes in the United Kingdom (UK). The emergence of the “religious nones” is the most obvious sign of continuing secularization and the declining social and cultural relevance of religion. Yet while the religiously-unaffiliated often form the plurality — if not so...
choline oxidase (chox) was chosen as a model enzyme for evaluating the performance of cnts’ functional groups for development of enzyme electrodes. cnts were functionalized with carboxylic acid, amine or amide groups. carboxylic acid, amine and amide functionalized cnts were obtained by acid treatment, ethylenediamine or tetraethylenepentamine chemically modification and ammonia plasma treatmen...
Introduction & Objective: The practice of eliminating pathogenic microorganisms in water dates back to ancient times. The most common methods for water disinfection are using chemicals, Ozonation, Ultra Violet ray, Membrane Processes and etc. There has been considerable interest in disinfection of water by using electrochemical methods in recent years. The main purpose of this study is to con...
abstract wenner direct contact method is a method of estimating apparent electrical conductivity (eca) of agricultural soils in situ. this method can be affected by factors such as quality of electrodes in contact with soil, type of employed electric current, moisture content, clay content and compaction of soil. in this research, the effect of electrode type (rod and plate) and electric curren...
groundwater makes up an important part of global freshwater resources, though it is often threatened by overuse of natural resources along with abundant production of wastes in modern society. this study aims to investigate the removal of three heavy metals including nickel, cadmium, and lead from groundwater via electrocoagulation, a suitable method for treatment of water-soluble compounds, de...
In this paper, we analyzed the influence of changing the material of electrodes on the transport properties of single junction comprising GNR (Graphene Nano Ribbon) stringed to two semi-infinite electrodes using semi empirical model. The investigation of electron transport through GNR was accomplished by linking it to different metallic electrodes (Pt, Au and Ag) under different bias voltages w...
In this work, for eliminating the (RR1346), considered to be a waste in wastewater from dye industries electrochemical advanced oxidation process has been used. Graphene oxide coated carbon cloth (GO/CC) and Fe3O4 /GO coated carbon cloth (Fe3O4/GO/CC) electrodes has been fabricated by synthesized GO and Fe3O4 nanoparticles. Characteristic properties such as surface morphology as the main reason...
