Coatings of specific materials in few atoms of thickness to several microns on certain substrate is the basic need of society and they attend the regular attention of scientific community working in different domains; decorative and protective coatings, transparent and insulating coatings, coating medical implants and surgical instruments, coatings for drug delivery and security purposes, ultra...

Pb(Zr,Ti)O3 compositions are under investigation for applications that include integrated capacitors, piezoelectric sensors, and actuators. Sol–gel synthesis and spin coating are popular routes to the formation of high quality, dense, crack free, insulating films. However, the electrical properties of the films are often different than those measured for bulk specimens of the same composition. ...

The paper discusses a method for reducing electricity losses on high-voltage power lines through the use of new insulating coating, action which is based effect “blocking layer”. study samples free-flowing and flexible dielectric regarding possibility implementing proposed coating presented. Possible combinations materials covering wires are analysed, as well results computer modelling experime...

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...

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...

Thin bonded films have many applications in antireflection and reflection coating, insulating and conducting films and semiconductor industries. Thermal conductivity is one of the most important parameter for power packaging since the thermal resistance of the interconnections is directly related to the heat removal capability and thermal management of the power package. The defects in material...

Carbon nanotubes (CNTs) are considered the most promising candidates to replace Cu and Al in a large number of electrical, mechanical and thermal applications. Although most CNT industrial applications require macro and micro size CNT fiber assemblies, several techniques to make conducting CNT fibers, threads, yarns and ropes have been reported to this day, and improvement of their electrical a...
