In the monograph of F. I. Samedova "The application of supercritical fluids in petroleum refining and oil fractions" (Baku, 2014) the results of the use of supercritical fluids in petroleum refining and petroleum products are presented. The investigations were made under the guidance of the corresponding member of the Azerbaijan National Academy of Science, professor F. I. Samedova and representatives of the scientific school she has established: Doctor of Technical Sciences R. Z. Gasanova, Ph.D. A. M. Kasumova, Ph.D. S. Y. Rashidova and N. F. Kafarova, as well as with representatives of the spectral laboratory Ph.D. A. D. Kuliyev and Ph.D. B. M. Aliyev. Scientific editors of the monograph are academics M. I. Rustamov and V. M. Abbasov. The recent advances in term of the possible applications of supercritical extraction processes in the field of oil refining and oil fractions are shown. The analysis of the economic efficiency of supercritical extraction processes using SC CO2 is carried out. The scheme of the pilot plant at the Experimental Plant of the Institute of Petrochemical Processes of Azerbaijan National Academy of Sciences (IPCP of ANAS) is described. The monograph [1] is intended for researchers, graduate students, engineers and graduate students engaged in the development and introduction of new energy-saving and environmentally friendly technologies for oil refining and oil fractions. In order to find the ways to create energy-efficient, environmentally-friendly technologies in 1970 the use of supercritical fluids as solvents in cleaning processes, extraction, separation and fractionation are proposed. This approach can lead to the creation of environmentally friendly processes in the food, perfumery, pharmaceutical, oil, coal processing industry and in the field of polymer processing. Considering the need of creation of environmentally friendly and energy-saving technologies in the oil refining industries, in 2000 IPCP of ANAS began the research on the intensification of processes used in the oil industry-oil refining and heavy fractions of water, salts and solids, high molecular heteroatom-F. I. Samedova et al. 18 ic compounds: resinous-asphaltene substances including the metals using a supercritical fluid. The monograph highlights the results of studies on the use of supercritical fluid SC CO2 emissions from petroleum refining and oil fractions with a view to their intensification and ecological rehabilitation of the environment.
It is widely accepted that the lipid compositions of the plasma membranes of healthy and cancer cells significantly differ from each other. During the cancer progression, cancer cells change the lipid constituent of the membranes resulting in the loss of lipid asymmetry between the membrane leaflets. Consequently, physicochemical properties of the cell membranes are also changed in response to altered lipid organization. Partitioning of the spin probe 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) into the membranes of the cells has broadly been applied to characterize membrane properties of various cells in health and disease conditions. In this work, we used liposomes fabricated using lipids extracted from normal and carcinoma cells. This system permits the determination of the properties of the healthy and cancer cell membranes provided exclusively by its lipid components. Application of TEMPO-benzoate, in which the benzoate group is attached to the TEMPO, indicates significantly enhanced discrimination of liposomes between cancer and normal cells. Partitioning experiments with TEMPO-benzoate revealed relatively enhanced incorporation efficiency for liposomes of cancer cells. On the contrary, TEMPO incorporation efficiency in the same liposomes of cancer cells was not much different compared to healthy cells. Data indicate that TEMPO-benzoate as a probe is more suitable than TEMPO to discriminate cancer cells from healthy cells. Free energy gain observed for TEMPO-benzoate resulted mainly from the hydrophobic effect of the benzoate group.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
