Development and application of biocompatible lubricants are increasing daily as a result of stringent regulations imposed on mineral oil-based lubricants with their non-biodegradable toxic wastes. Before consumer acceptance of vegetable oil-based lubricants, they must overcome certain poor performance characteristics such as thermal and oxidative instabilities. This work demonstrates the improv...

In many cases, especially those involving sexual assault, forensic scientists are searching the biological evidences such as blood, skin, hair, saliva, urine, semen for DNA analysis. Recently, the uses of condoms in sexual assault cases were increasing to avoid leaving the biological traces in the crime scene. In these cases, finding the condom lubricant traces from the victims can be valuable ...

There is a need to improve conventional polyolester lubricants that are currently being evaluated as the optimal refrigeration base oil for the alternative refrigerants R41 OA and R407C, which are expected to be designated as the replacement ofHCFC 22. Prior studies show that the conventional polyolesters and other lubricants have poor hydrolysis and solubility. This paper is an introduction to...

Ionic liquids (ILs) are finding technological applications as chemical reaction media and engineering fluids. Some emerging fields are those of lubrication, surface engineering and nanotechnology. ILs are thermally stable, non-flammable highly polar fluids with negligible volatility, these characteristics make them ideal candidates for new lubricants under severe conditions, were conventional o...

KUMBÁR VOJTĚCH, DOSTÁL PETR: Oils degradation in agricultural machinery. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2013, LXI, No. 5, pp. 1297–1303 Evaluating of oils condition in agricultural machinery is very important. With monitoring and evaluating we can prevent technical and economic losses. In this paper there were monitored the liquid lubricants taken from m...
