In the work the investigations of the effect of abnormally high electric conductivity of surface of the air-electrolyte interface during electrolytic decomposition of water were continued. Experiments were carried out both at alternating current via the bridge circuit and at direct current in the four-electrode cell. Previously, it was shown that in thin air-bordering electrolyte layers specific conductivity measured in the four-electrode cell during electrolysis of water exceeds the corresponding value measured with the bridge circuit for solutions of sodium hydroxide by 1.5 times, for soluti

In ReRAM memory crossbar architecture, heat accumulated in one cell transfers to nearby cells via shared electrode metal lines and impacts adversely the performance of the devices. The cell-to-cell heat transfer leads to reduced number of switching cycles (SWC) and, in specific circumstances, to a loss of a bit in the cell brought about by a rupturing of the nanofilament.

These solutions, such as supercapacitors and batteries, are vital for portable electronics, electric vehicles, and hybrid vehicles. Two-dimensional (2D) materials, characterized by their high lateral size-to-thickness ratio, offer unique physicochemical properties, such as large specific surfaces for adsorption of ions, high conductivity for transporting electrons, and flexible active sites for electrocataly

A new theory is introduced to describe the response of thermoelectric modules and materials in the presence and absence of both electrical and thermal power sources, assuming that the thermoelectric modules and materials are capacitors capable of storing electrical and thermal energy at the same time. The theory here described is designed by resolving the thermal components, and satisfies Newton’s cooling law, Luttinger’s thermal transport coefficients theory, and first and second-order electric circuit behavior. An especially useful feature is that a new equation for the thermoelectric figure

The physical and chemical properties of crystals and textured materials often depend on direction. An understanding of anisotropy requires a mathematical description together with atomistic arguments to quantify the property coefficients in various directions. Tensors and matrices are the mathematics of choice and the atomistic arguments are partly based on symmetry and partly on the basic physics and chemistry of materials. These are subjects of this book: tensors, matrices, symmetry, and structure–property relationships. We begin with transformations and tensors and then apply the ideas to t

Abstract Compared to other polymeric materials, silicone offers greater performance in harsh environments. Inherently silicone possesses a large coefficient of thermal expansion (CTE), low modulus, and a low glass transition temperate (Tg). These attributes allow it to maintain elastomeric properties for continuous operation when exposed to extreme heat, cold, and/or UV radiation. Durability is the reason silicone materials are frequently employed as coatings and sealants. In electronic equipment, silicone coatings protect device functionality amidst temperature fluctuations during use. On the

Abstract One of the more significant aspects of galvanic corrosion in mechanical joints of military electronics equipment, other than mechanical integrity, is the resultant loss of electrical conductivity across the joint, and hence a loss of shielding effectiveness. This prevalent problem for EMI shielded electronics equipment which must operate in the marine environment is not effectively addressed during normal system qualification tests. Further, it is typically not properly addressed for fielded systems, even after maintenance, repair or refurbishment of equipment. Evaluations of shieldin

Abstract On-line, real time corrosion monitoring in processes featuring low conductivity fluids akin to sulfolane aromatic extraction, have represented a challenge for traditional electrochemical techniques. Sulfolane specific conductance that is typically about 5μS/cm disables proper determination of corrosion current with standard Linear Polarization Resistance (LPR) technology. Other electrochemical techniques such as Electrochemical Impedance Spectroscopy (EIS) or Zero Resistance Ammetry (ZRA) that are capable to measure corrosion in low conductive fluids are useful mostly in laboratory pr

Abstract The determination of the concentration of soluble salts on a surface prior to the application of paint is a key inspection task for most protective coating processes. The entrapment of soluble salts, particularly on a steel surface can lead to premature coating adhesion failure and corrosion cells being established. This leads to a severe reduction in the expected life of the protective paint system.

Abstract A high energy electron linear accelerator (LINAC) is capable of generating intense bremsstrahlung that approximates the gamma dose rate in the core of a boiling water nuclear reactor (BWR). Experiments with radiation hardened platinum, pH and silver/silver chloride electrodes at BWR operating temperatures in a stainless steel autoclave showed reversible, stable voltage offsets that depended on water chemistry and radiation intensity. These changes occurred slowly, and the potentials required several minutes to attain a steady state. Even with a remote reference, it is not possible to

Abstract. Present study aims at modelling the impact of tool materials such as copper, tungsten carbide and brass tool on the electric discharge machining of AISI 202 stainless steel. It is well known that the electrical conductivity of tool material has an influence on the current density passed through interelectrode gap and hence sparking process and MRR are affected accordingly. A finite element model was made using gaussian heat flux equation, spark radius and fraction of heat transferred to workpiece as a function of pulse on time and pulse current, latent heat in specific heat values an

Polypyrrole (PPy) was chemically prepared via an in situ doped polymerization utilizing seven dopant anions (dopant to monomer molar ratio, D/M = 1/12) to stabilize the positive charges on N of pyrrole rings. These dopant anions were found to play important roles on physical, chemical, and electrical properties of PPy as revealed by several techniques, e.g. X-ray photoelectron spectrometer and the custom-made four-point probe conductivity meter. PPys doped with alpha-naphthalene sulfonate (PPy/A) and beta-naphthalene sulfonate (PPy/B) have good pellet appearance, solubility, thermal stability,

Time Domain Reflectometry (TDR) and other in-situ and remote sensing dielectric methods for determining the soil water content had become standard in both research and practice in the last two decades. Limitations of existing dielectric methods in some soils, and introduction of new agricultural measurement devices or approaches based on soil dielectric properties mandate improved understanding of the relationship between the measured effective permittivity (dielectric constant) and the soil water content.
