Abstract The paper presents new results on the application of microplasma spraying (MPS) for manufacturing electric heating elements (EHEs) consisting a St3 steel plate (the substrate) with sprayed electrically insulating Al 2 O 3 sublayer (400±50 μm thick) and TiO tracks (4 mm width; 150±50 thickness). Measurements temperature multilayer coating thermal imager enabled determination distributio...

─ Due to the limited size of antenna and electromagnetic loss of human head tissue, implantable miniaturized antennas suffer low radiation efficiency. This work presents simulation and analysis of implantable antennas for a wireless RF-powered brain machine interface applications. The accuracy and stability of antenna input impedance simulation are presented. The effects of the implanted antenn...

A major loss mechanism in dye-sensitized solar cells (DSCs) is recombination at the TiO(2)/electrolyte interface. Here we report a method to reduce greatly this loss mechanism. We deposit insulating and transparent silica (SiO(2)) onto the open areas of a nanoparticulate TiO(2) surface while avoiding any deposition of SiO(2) over or under the organic dye molecules. The SiO(2) coating covers the...

We study the maximum temperature rise induced by a rotating or dithering Gaussian laser beam on a two-layer body. First, we derive semi-analytical solutions by solving the transient threedimensional heat equation in a semi-infinite domain with insulating surface. Second, we provide numerical solutions for a two-layer structure in a finite domain. Our results show that the maximum temperature ri...

The relationship between the sperm-coating antigens of rabbit seminal plasma and the phenomenon of decapacitation was studied using agar-gel diffusion, immuno-electrophoresis, chromatography on Sephadex G-200, and polyacrylamide vertical gel electrophoresis. Interpretation of data obtained with these techniques led to the conclusion that a sperm-coating antigen of seminal plasma origin possesse...

It has been known that a high-emissivity furnace provides an energy-efficient alternative to a conventional furnace [1,2]. To improve the efficiency of a furnace, ceramic coatings with high emissivity are often applied to the interior of the furnace. The purpose of this paper is to show the amount of electrical energy-saving achieved by emissive carbon coating for a tubular vacuum-furnace. Alum...

Thermal barrier coatings (TBCs) are a fundamental technology used in high-temperature applications to protect superalloy substrate components. However, extreme environments present many challenges for TBCs, such as the degradation of their thermal and mechanical properties. Hence, highly insulating, long-life TBCs must be developed meet higher industrial efficiency. This paper reviews main fact...
