Abstract:
AbstractTranscutaneous Spinal Direct Current Stimulation (tsDCS) is a neuromodulatory technique that applies low intensity (2–4 mA) direct currents to the spinal cord through electrodes placed above or near the vertebral column. As in transcranial electric stimulation, tsDCS induces an electric field in the spinal cord that can transiently change the transmembrane potential of spinal neurons or influence synaptic communication. Anatomical features near the electrodes or in the current path can originate local variations of the electric field magnitude and orientation that result in different effects generated at neuronal and synaptic level. Accurate realistic models of the spinal cord and surrounding tissues can provide a deeper understanding on how and why these variations occur.Our research aims at studying how electrode placement interacts with electrical conductivities of the tissues located in the current path. Using a realistic human model of the spinal cord and surrounding tissues, we estimated the electric field induced by tsDCS, considering different combinations of electrode positions and electrical conductivity of relevant tissues. Our study started from a homogeneous conductivity paradigm up to a full heterogeneous model. The results show that electrode placement influences the electric field orientation, while the conductivities of vertebral bone and CSF can lead to local electric field hotspots in spinal segments located in the current path. Understanding the interplay between these two effects can provide a solid framework to target specific spinal circuits in terms of magnitude and field orientation towards a more personalized approach.

Abstract The overall aim of the SUBLIME (Solid state sUlfide Based LI-MEtal batteries for EV applications) project is to respond to the further battery development challenges for Electric Vehicles and produce next-generation solid-state batteries (SSB) with extreme high energy density of up to 450 Wh/kg as compared to 250–280 Wh/kg for conventional cells to double the driving range of electrical vehicles. The SUBLIME cell consists of a sulfide solid electrolyte (SE), Li metal anode and high nickel content cathode (NMC based). Up to now, we have overcome several challenges of this technology. The sulfide SE has been produced in kilogram scale with high ionic conductivity of 2.5 mS/cm at 25 ℃ and specific cathode and Li metal anode were developed for SSB application. The quality of the developed materials was confirmed in coin cell format, delivering a capacity of 195 mAh/g at 25 ℃. Next, we have been focusing on producing mono and multilayer pouch cells based on scalable process and optimizing the interfacial resistances between the cell components. For this purpose, coatings are applied on Li metal anode and cathode active material. The initial testing results of the pouch cells demonstrate the potential of this technology.

Abstract:
The next six chapters describe the transport phenomena associated with the flow of charge, heat, and matter. In each case there is a vector flux that is governed by a vector field. Linear relationships between flux and field include electrical resistivity (Chapter 17), thermal conductivity (Chapter 18), diffusion (Chapter 19), and thermoelectricity (Chapter 21). All are represented by second rank tensors similar to electric permittivity (Chapter 9), but the underlying physics is somewhat different. Transport properties are nonequilibrium phenomena governed by statistical mechanics and the concept of microscopic reversibility, rather than the second law of thermodynamics that applies to equilibrium properties such as specific heat, permittivity, and elasticity. Higher order tensors appear when the transport experiments are carried out in the presence of magnetic fields or mechanical stresses. Galvanomagnetic, thermomagnetic (Chapter 20), and piezoresistance effects (Chapter 22) require third- and fourth-rank tensors. When an electric field is applied to a conductor, an electric current flows through the sample. The field Ei (in V/m) is related to the current density Jj (in A/m2) through Ohm’s Law, where ρij is the electrical resistivity (in Ω m). In tensor form, . . . Ei = ρijJj . . . Ei and Jj are polar vectors (first rank polar tensors) and ρij is a second rank polar tensor property which follows Neumann’s law in the usual way. Sometimes it is more convenient to use the reciprocal relation involving the electrical conductivity σij : . . . Ji = σijEj . . . .

Polymers have wide range of applications in all human activities. Recent policies on environment and resource efficient mean that new efficient production and engineering processes need developing. This paper presents a new approach of laser irradiation of polymer aiming at inducing specific conductivity properties. Under the influence of a CO2 laser irradiation of polymers in the air, new macromolecular chemical and physical structures were engendered, which have electrical conductivity and paramagnetic properties. The conductivity of these substances are due to formation of carbon chains with conjugated double bonds and paramagnetic centres due to free radicals and charges localized around the structural defects near the surfaces of polymer sheet. The results show the formation of electrical conducting channels with desirable configuration in very short time without high vacuum, which can be used for production of printed circuits.

: Recently, carbon-based nanomaterials (CBNM) have been widely used for chemical and biosensing applications due to their outstanding physicochemical properties, such as mechanical, thermal, optical, electrical and structural diversity. Such materials include carbon nanotubes, graphene oxide, graphene quantum dots and fullerene. As a consequence of inimitable features, these give superior strength, electrical conductivity, and flexibility toward numerous chemical and biological objects, which is valuable for chemical sensing and biosensing purposes. However, the specific intrinsic property makes graphene and carbon nanotubes (CNTs) most attractive among the various allotropes of carbon. Since the environmental contaminants in ppm level affect the people, therefore the use of CBNM for environmental sensing provides an accessible cache of data for modelling, which makes it easy to monitor environmental challenges. Thus, the biological, chemical, thermal, stress, optical, strain and flow sensors deliver a larger surface area, excellent electrical conductivity with chemical constancy, as well as mechanical difficulty with straightforward functionalization pathways of CNTs to improve old-style carbon electrode sensor platforms. Therefore, in this chapter, the CBNM for sensing purposes are focused in detail on their mechanism.

Abstract:
Energy harvesting has been proposed as a promising method of supplying electric power to autonomous sensor network devices and mobile electrical instruments due to the possibility of obtaining electric power from unused environmental energy, such as heat, light, and vibrations. It was found that micro-generators for energy harvesting are more useful than standard electrical batteries. Lead telluride alloys are the first materials investigated and commercialized from micro- to macro-generators with electrical power up to a few hundred watts. However, their full potential for thermoelectrics has only recently been revealed to be greater than commonly believed. The maximal value of the thermoelectric figure of merit as a function of electron density is attained only for the specific location of the Fermi level EF relative to the conduction band edge Ec. A systematic study of structural, micro-structural, and thermoelectric properties of bulk and film PbTe doped with indium is presented. Bulk samples were prepared utilizing a Spark Plasma Sintering. The films with high energy conversion efficiency were deposited on a polyimide substrate using a flash evaporation technique. A systematic study of the Seebeck coefficient, and electrical and thermal conductivity of Pb1−xInxTe bulk and film samples over a wide temperature range has been performed.

Abstract:
Soil characterization and process monitoring in small-scale tests such as 1g models, shake table and centrifuge models can be effectively conducted with complementary elastic and electromagnetic waves. Small changes in P-wave impedance permit developing P-wave reflection imaging. Its implementation using ultrasound in small-scale soil models is attained by optimizing the operating frequency and selecting the proper transducers. The technique permits detecting layers and inclusions in submerged soils with sub-millimeter resolution. S-wave velocity depends on the shear stiffness of the skeleton. Shear wave propagation gains particular relevance in the characterization of uncemented soils where stiffness is stress dependent. Bender elements are excellent transducers for S-waves due to their outstanding soil-transducer coupling and their high frequency response. The installation can be designed to gather tomographic data. The electrical conductivity of a soil depends on the conductivity of the pore fluid, porosity and the soil specific surface. High-resolution electrical resistivity profiles are determined using an electrical needle probe. These profiles provide detailed information regarding the spatial variability of the soil mass with millimeter resolution. Resistivity measurements are extended to noninvasive electrical resistance tomography to produce images that correlate to density distribution, contaminant concentration, and/or anomaly detection.

Abstract:
Image reconstruction by electrical impedance tomography is, generally, an ill-posed nonlinear inverse problem. Regularization methods are widely used to ensure a stable solution. Herein, we present a novel electrical impedance tomography algorithm for reconstruction of layered biological tissues with piecewise continuous plane-stratified profiles. The algorithm is based on the reconstruction scheme for piecewise constant conductivity profiles, which utilizes Legendre expansion in conjunction with improved Prony method. This reconstruction procedure, which calculates both the locations and the conductivities, repetitively provides inhomogeneous depth discretization, (i.e., the depths grid is not equispaced). Incorporation of this specific inhomogeneous grid in the widely used mean least square reconstruction procedure results in a stable and accurate reconstruction, whereas, the commonly selected equispaced depth grid leads to unstable reconstruction. This observation establishes the main result of our investigation, highlighting the impact of physical phenomenon (image theory) on electrical impedance tomography, leading to a physically motivated stabilization of the inverse problem, (i.e., an inhomogeneous depth discretization renders an inherent regularization of the mean least square algorithm).

Abstract:
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 Aluminum, after iron is the second -most widespread metal used on earth. Unpainted aluminum forms a protective aluminum oxide layer over the pure aluminum metal alloy and, in most atmospheric environments, is resistant to corrosion deterioration. However, pure aluminum is virtually always alloyed with other metallic elements to enhance its properties, primarily to increase its strength, but also to improve its formability, weldability, machineability, electrical conductivity, and corrosion resistance. There are many circumstances in which aluminum alloys are prone to corrosion and req

Abstract Research has indicated the problem of microbial resistance to nonoxidising biocides. Very little information is further more available on the biodegradability of these compounds in natural water systems. This makes these compounds hazardous from an environmental point of view. Chlorine is the most widely used oxidizing biocide, with its own limitations. An environmentally sensible alternative to chlorine and other commonly used biocides is needed. Electrochemically activated water (ECA) solutions, may provide such an alternative. Water of varying mineralisation is passed through an el

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 “The Perfect Finish” is something that the industry has been seeking for years. It is an elusive concept for which millions of dollars have been spent in developing, testing and qualifying possible alternative finishes, but most of these efforts are futile. In order for engineers to be most effective, a realization must be made that each finish, from phosphate to cadmium, has strengths and weaknesses that must be weighed in considering each application. It is with these considerations that progress can be made toward using the materials that have the closest resemblance to the qualiti

Further, it is typically not properly addressed for fielded systems, even after maintenance, repair or refurbishment of equipment. Evaluations of shieldin

Abstract In fires, corrosive chemicals are generated along with the other combustion products, which are present as gases, liquids and solids.1 Corrosive chemicals (such as HCl, HBr, and HF) are commonly emitted as gases and liquids with inorganic atoms in the structure. Non-corrosive combustion gases and liquids are emitted as organic compounds and water, whereas solids are emitted as soot, inorganic metals, and dust. As a result, corrosion caused by smoke generated after a fire is due to the presence of acid gases (e.g., HCl, HBr, and HF) in smoke plus moisture/water in the environment.2,3 D
