Biodeterioration of optical glass induced by lubricants used in optical instruments technology.
The process of biodeterioration of optical glass was studied after being induced by an auxiliary material (lubricant 4CKP) used in the production of optical instruments. It was determined that the lubricant can initiate growth of conidia of Aspergillus niger fungus. Acid spawn metabolites cause deterioration of the glass surface. Measurements of laser light beam transmittance through the glass ...
متن کاملPalm oil derived trimethylolpropane triesters synthetic lubricants and usage in industrial metalworking fluid.
Trimethylolpropane triesters are biodegradable synthetic lubricant base oil alternative to mineral oils, polyalphaolefins and diesters. These oils can be produced from trimethylolpropane (TMP) and fatty acid methyl esters via chemical or enzymatic catalyzed synthesis methods. In the present study, a commercial palm oil derived winter grade biodiesel (ME18) was evaluated as a viable and sustaina...
متن کاملSynthetic Lubricants Can Inhibit the Development of Osteoarthritis in a Guinea-pigmodel
+ Clarke, M T; + Lee, P T H; + Rushton, N. + University of Cambridge, England. Introduction Osteoarthritis (OA) is a degenerative condition of synovial joints involving the destruction of articular hyaline cartilage. In the 1970’s, ‘viscosupplementation’ with hyaluronan was proposed as a potential treatment for OA with the idea that it would improve joint lubrication. However, despite studies s...
