abstract:any effects of wood coating with different compounds as nano-zinc, nano-chitosan, chitosan, silicon oil and flaxseed oil on surface properties as; wood color change, surface roughness and wettability were studied in the current research work. for this purpose, sample boards of beech wood were cut into sizes of 2×10×20cm. the specimens were coated with the noticed coatings and tested fo...

This review deals with different aspects of hydrophobicity at nanostructured surfaces. Theoretical and geometric effects as well those surface feature geometry on are explored in this article. includes modification methods used to change effect adhesion cells nano substrate. A small chapter is devoted self-assembled monolayers a special type surface. To the models describing one up dated chapte...

phospholipase a1 is known as an effective catalyst for hydrolysis of various phospholipids in enzymatic vegetable oil degumming. immobilization is one of the most efficient strategies to improve its activity, recovery and functional properties. in this study, chitosan-co-polyethylene oxide (90:10) nanofibrous mat was successfully fabricated and modified with atmospheric plasma at different time...

Lithium-ion batteries have attracted widespread attention as new energy storage materials, and electrode especially cathode are the main factors affecting electrochemical performance of lithium-ion batteries, they also determine cost preparing batteries. In recent years, there been a lot researches on selection modification materials based to continuously optimize This article introduces resear...

a hydrothermal method for preparation of nano-size zirconia has been studied to optimize the effective parameters (precursor concentration, temperature and time) using response surface methodology (rsm). the synthesized zirconia samples were characterized through x-ray diffraction (xrd), scanning electron microscope (sem) and transmission electron microscopy (tem) analyses to identify mean nano...

The recycled aggregate obtained by simple crushing and screening of waste concrete has a rough surface many protruding edges corners, most the is attached with old mortar, when directly used as in concrete, water demand large, strength elastic modulus are low, durability poor. Therefore, proper treatment required.This article summarizes research status pretreatment methods mechanical strengthen...
