Mucins secreted by mucus-producing cells are glycoproteins with many important functions such as antimi crobial effect, lubricity and physical barrier. The structure function of mucins may be different in various tissues. Therefore, we designed our study to reveal the current state mucin chemistry glands located partridge's esophagus. esophagus total 10 adult partridges, five female male, whose...

Depletion of mineral reservoirs along with health and environmental concerns have led to a greater focus on bio-lubricants. The purpose this study was analyze optimize the reaction conditions transesterification process for cotton biolubricant synthesis by using Response Surface Methodology (RSM). In RSM, Rotatable central composite design selected examine effect input factors yield bio-lubrica...

About 40 million tons of lubricants are used every year for various industry purposes and applications, where most them petroleum based oils. These oils difficult expensive to dispose of, have low biodegradability contamination risks. Recent efforts been focused on reducing the environmental impact through use vegetable since they biodegradable good lubricity. A drawback is their poor thermal s...

Abstract This study demonstrates that magnetron-sputtered NbSe 2 film can be used as a lubricant for space current-carrying sliding contact, which accommodates both metal-like conductivity and MoS -like lubricity. Deposition at low pressure energy is performed to avoid the generation of interference phase 3 . The composition, microstructure, properties films are further tailored by controlling ...
