In the high temperature combustion atmosphere inside of aircraft turbines, currently used ceramic matrix composites require a protective environmental barrier coating (EBC) to mitigate corrosion turbine parts. Besides thermomechanical and thermochemical properties like matching thermal expansion coefficient (CTE) resistance against corrosive media, mechanical adhesion strength are also necessar...

Caveolins are a family of proteins that coat the cytoplasmic face of caveolae, vesicular invaginations of the plasma membrane. These proteins are central to the organization of the proteins and lipids that reside in caveolae. Caveolins transport cholesterol to and from caveolae, and they regulate the activity of signaling proteins that reside in caveolae. Through studying the genes encoding the...

The ultrastructure of epimastigotes of Trypanosoma cruzi, obtained from acellular cultures, and bloodstream trypomastigotes, isolated from infected mice, were studied by thin-sectioning and freeze-fracturing techniques. Epimastigotes showed a thin (5 nm) surface coat when stained with ruthenium red, while the surface coat of trypomastigotes was more prominent (15 nm thick). Both P and E faces o...

Nanostructured ceramic coatings produced by plasma spray processes are being developed for a wide variety of applications that require resistance to wear, erosion, cracking and spallation [1]. In addition the process is being developed to make near net shaped ceramic performs by dissolution of the substrate after spraying. Attractive properties associated with a nanostructure (in general referr...

Thermal spray in general, plasma spray in particular, is a highly complex process with numerous interacting variables associated with generation of the spray stream, deposit formation dynamics, and the resultant property linkages. Compounding this variability further are both the spatial (different booths and different locations) and temporal (process start-stops, hardware degradation, operator...

THERMAL SPRAY is a generic term for a group of processes in which metallic, ceramic, cermet, and some polymeric materials in the form of powder, wire, or rod are fed to a torch or gun with which they are heated to near or somewhat above their melting point. The resulting molten or nearly molten droplets of material are accelerated in a gas stream and projected against the surface to be coated (...

Carbon fiber (CF) surfaces were prepared in order to enhance their cohesion polymer matrixes for composite applications. Among innovative methods allowing the modification of CF surface, plasma technologies, and more specifically on polymerization is known as an eco-process that allows size, i.e. coat strands with organic materials. Depending parameters chosen precursors, thin film surface phys...
