Study Of Methods For Developing Waste Lubricant Recovery, Sh T. Poyonov, S M. Turabdjanov

Technical science and innovation

The article provides analytical information on the study of methods of treatment of used engine oils. The issues of ecological safety of storage, processing and use of automobile waste are considered. The problems of ecological safety of application of lubricants are inseparable from utilization of OWS, which are currently one of the most common man-caused waste that negatively affects all objects of environment - atmosphere, soil and water. It has been shown that water pollution by waste oil accounts for 20% of total techno-genic pollution, or 60% of petroleum product pollution. The study determined that obtaining oils with characteristics superior …

Bulletin of Chinese Academy of Sciences (Chinese Version)

The rapid development of the information society puts forward an ever-increasing urgent need for information storage, processing, and transmission capabilities. With the ending of Moore's Law, the semiconductor industry urgently needs to find new solutions. Lowdimensional materials are considered to be a new breakthrough in the semiconductor industry in the post-Moore era, because of the size characteristics of atomic-level thickness, the structural advantage of no dangling bonds on the surface, and the sensitivity to electrical and optical control methods caused by a large specific surface area. Songshan Lake Materials Laboratory has introduced a group of top scientists and established a …
