Vertical carbon nanotube (CNT) forests bonded at room temperature with sprayed on nanoscale polymer coatings are found by measurement to produce thermal resistances that are on a par with those of conventional metallic solders. These results are achieved by reducing the high contact resistance at CNT tips, which has hindered the development of high performance thermal interface materials based ...

conventional and nanostructured ysz coatings were deposited on the in-738 ni super alloy by the atmospheric plasma spray technique. the oxidation was measured at 1100°c in an atmospheric electrical furnace. according to the experimental results the nanostructured coatings showed a better oxidation resistance than the conventional ones. the improved oxidation resistance of the nanocoating could ...

In atomic force microscopy, cantilevers with a reflective coating are often used to reduce optical shot noise for deflection detection. However, static AFM experiments can be limited by classical noise and therefore may not benefit from a reduction in shot noise. Furthermore, the cantilever coating has the detrimental side-effect of coupling light power fluctuations into true cantilever bending...

Evaporating liquid layers are found in many areas of science and technology, so their practical significance is rather high. Examples include evaporative cooling and numerous coating applications. In the latter a substrate is coated with a layer of solution which, upon the evaporation of solvent, leaves a layer of solute on the surface of the substrate. The main difference between various coati...

High energetic aluminum nanoparticles are mainly used as additive in solid rocket propellants. However, fabrication of these aluminized energetic materials is associated with decreasing the burning rate of propellants due to problems such as oxidation and agglomeration of nanoparticles. In this study, to improve combustion performance of aluminum nanoparticles, coating by metallic Ni shell...

A new technique was accepted to fill the porosity of Al coating applied by arc thermal spray process to enhance corrosion resistance performance in artificial ocean water. The porosity is the inherent property of arc thermal spray coating process. In this study, applied coating was treated with different concentrations of ammonium phosphate mono basic (NH4H2PO4: AP) solution thereafter dried at...

Multiple layers of polyvinyl alcohol (PVA) coating are generated onto silica gel by thermal immobilization to form a stationary phase applied for hydrophilic interaction liquid chromatography (HILIC). It offers an easy way to manipulate the thickness of PVA coating and the obtained stationary phase demonstrated high efficiency and high chemical stability.

Thermal barrier coating (TBC) systems are coating systems containing a metallic bond coat and a ceramic top coat. TBCs are used in gas turbines for thermal insulation and oxidation resistance. Life prediction of TBCs is important as high-temperature exposure degrades the coatings through mechanisms such as thermal fatigue and the formation and growth of thermally grown oxides (TGOs). This thesi...

The passive thermal control of a satellite consists establishing the necessary parameters involved in process heat transfer by radiation and conduction order to delimit range temperatures which different components will be exposed. If obtained implies that elements are unable cope with, therefore, an external is demanded. This work deals with programming equilibrium problem taken into considera...
