The cavity wall is an important part of a receiver in determining the efficiency. Using solar selective reflector (SSR) materials with low absorptivity and high thermal emissivity for design one efficient way to improve In this work, we present systematic study optical high-temperature stability performances six different SSR materials: refractory ceramic fiber based substrate material (Fiberfr...

Mesoporous Ni–alumina catalysts (Ni–alumina-pre and Ni–alumina-post) were synthesized by one-step sol–gel method using micelle complex comprising lauric acid and nickel ion as a template with metal source and using aluminum sec-butoxide as an aluminum source. The Ni–alumina catalysts showed relatively high surface areas (303 m/g for Ni–alumina-pre and 331 m/g for Ni–alumina-post) and narrow por...

Abstract In this study, the alumina layer on surface of aluminum powder was removed with hydrofluoric acid. 2-Azido-1,3-dimethylimidazolinium Hexafluorophosphate (ADMHFP) and 4-azido-2,3,5,6-tetrafluorobenzoic acid (ATFBA) were coated to form Al@ADMHFP Al@ATFBA. Scanning electron microscope FTIR test results proved that ADMHFP ATFBA powder. The Al@ATFBA showed better thermal reaction combustion...

Abstract A method is specified which enables lifetime calibration of multiple phosphors and emission lines at the same time to temperatures above 1900 K. The experimental setup algorithm used for data collection equipment control are described. were coated on an alumina oxide disc reference temperature was measured using three type B thermocouples. automates process such that no input from oper...

The purpose of this paper is to examine the piston stress distribution using several thicknesses of the coating materials to achieve higher gasoline engine performance. First of all, finite element structure analysis is used to uncoated petrol piston made of aluminum alloy. Then, steel and cast iron piston materials are conducted and compared with the aluminum piston. After that, investigation ...

A bi-functional nano-composite coating has been created on a porous Nomex® fabric support as a trap for aspirated virus contaminated water. Nomex® fabric was successively dip-coated in solutions containing cysteic acid functionalized alumina (alumoxane) nanoparticles and cysteic acid functionalized iron oxide (ferroxane) nanoparticles to form a nanoparticle coated Nomex® (NPN) fabric. From SEM ...
