This paper presents an overview on the use of various classes nanomaterials in lubricant formulations. The following are considered: fullerenes, nanodiamonds, ultradispersed boric acid and polytetrafluoroethylene (PTFE). Current advances using engine oils, industrial lubricants greases discussed. Results numerous studies combined with formulation experience authors strongly suggest that do indeed have potential for enhancing certain properties, yet there is a long way to go before balanced...
The problem of utilizing plant wastes the agro-industrial complex is equally important and urgent.In this regard, it advisable to develop a technology waste application solve ecological problems environmental pollution with heavy metals.Modification walnuts shells orthophosphoric acid has proven be promising process for obtaining biosorbents efficient sorption properties.It was found out that increase in concentration inorganic modification time promotes improvement capacity.Such can used...
The paper provides a general overview of chemical processes leading to the degradation oil-paper insulation in oil-immersed electrical current transformers. Previous knowledge available literature is complemented by new results placing specific emphasis on physicochemical factors which affect copper release oil and oxidation kinetics. It demonstrated that various ageing interact with each other, one or another process dominating under conditions. Comprehensive but disjoint studies focusing...
