Polyaniline is a polymer material that has unique physical and even chemical properties, especially in its electrical properties. PANi synthesis can be carried out by electrochemical oxide reaction methods. The purposes of this study are to synthesize / Fe 3 O 4 composites reactions measure their conductivity. This research begins with the iron (Fe ) from natural sand then followed using copret...

In order to clarify the relationship between shielding gas flow and shieldability during a lap-fillet arc welding, oxygen concentration measurements on water-cooled copper which imitated lap-joint in tungsten inert welding were conducted. Moreover, high-speed plasma visualized by schlieren method observation using tube electrode xenon gas, respectively. As result, low-oxygen region, where was l...

Abstract A prime challenge in the development of new battery chemistries is fundamental understanding generation electrode–electrolyte interface (EEI) and its evolution upon cycling. Tip‐enhanced Raman spectroscopy (TERS) under an inert gas atmosphere employed to study chemical components anode/cathode electrolyte a sodium‐ion battery. After first cycle, TERS reveals that EEI mostly consists or...

The production of sodium hypochlorite (NaOCl) from salty wastewater using an electrochemical cell has several advantages over other methods that often require hazardous chemicals and generate toxic waste, being more sustainable environmentally friendly. However, the process producing requires careful control operating conditions, such as current density, flow rate, inert electrode spacing, elec...

• In the original inert gas method of Kety and Schmidt the saturation of the brain with the inert gas, N,,O, is followed for 10 minutes. In a group of subjects we have studied both the saturation and the desaturation of the brain with krypton as the inert gas. The results give an experimental demonstration of a relatively small systematic error inherent in the method apparently due to differenc...

In general, graph search can be described in terms of a sequence of searchers’ moves on a graph, able to capture a fugitive resorting on its vertices/edges. Several variations of graph search have been introduced, differing on the abilities of the fugitive as well as of the search. In this paper, we examine the case where the fugitive is inert, i.e., it moves only whenever the search is about t...

a novel chemically modified electrode containing prussian blue complex was achieved on the surface of glass carbon electrode by sol-gel technique. the electrochemical behavior of modified electrode was characterized by cyclic voltammetry in detail. the film electrode obtained was very stable and exhibited electrocatalytic response for oxidation of nitrite. results showed at bare gc electrode, a...

a sodium dodecyl sulfate modified carbon paste electrode (sds/cpe) was developed in this work based on the surface modification method. the modified electrode was prepared by immersing sds/cpe in a nickel nitrate solution. this electrode showed a strong accumulation ability toward nickel ions. then modified electrode was conditioned by potential recycling in a potential range of 0.2–0.8 v (vs. ...
