A New-PVE lubricant was developed for use with R32 refrigerant. R32 has been proposed as an alternative refrigerant for R410A refrigerant, to reduce global warming. In this report, we evaluated the relationship between the New-PVE lubricant and R32 and R410A refrigerants. The evaluation items were physical properties (miscibility, solubility, mixture viscosity and volumetric resistivity) and th...

Polysaccharides are often used as rheology modifiers in multiphasic protein-rich food systems. Recently, proteinaceous microgels have garnered research attention promising lubricating agents. However, whether can be to replace polysaccharides a tribological context remains poorly understood. In this study we compared the flow and oral-tribological behaviour of Newtonian solutions polysaccharide...

Summary Although advances in coating technologies have allowed us to match—or even exceed—the lubricity of Nature's low-friction surfaces, the performance synthetic materials inevitably diminishes over time as surfaces are worn and damaged by irreversible breakage covalent bonds. Synthetic systems lack bespoke repair mechanisms that replenish hydration lubrication Nature. Here, we demo...

Palmitoleic acid is a promising bactericidal agent for cleansing products with alternative bactericidal abilities. In this study, we focus on the physical and biological activity of palmitoleic acid calcium salt (C16:1 fatty acid Ca salt) because it forms via an ion-exchange reaction between palmitoleic acid and Ca ions in tap water, and remains on the skin surface during the cleansing process....

The lubricating properties of vegetable oil are well known. However, with the advent of petroleum oils, castor oil and other vegetable oils fell out of favor. The quality of petroleum oils has improved significantly in the last few years with the introduction of Group III base oils. However, even Group III oils fall short of the inherent lubricity of vegetable oils. Analogous to advances in pet...
