In the current work, a framework is presented for amine solvent selection in gas treating process. Since the appropriate decision making in this field affects the capital and operational costs, multi attribute decision making (MADM) techniques were used to rank alternatives. The determination of criteria and alternatives is the most important aspect in the MADM. Criteria were divided into two c...

• 3-Component Margules equation was used to predict vapor–liquid equilibria. Infinite dilution activity coefficients are the sole input for solvent pre-selection. Industrial cases were validate approach. Molecular solvents, ILs and DESs incorporated in screening. We present an easily accessible, open-access approach fast pre-selection of solvents extractive distillation at isobaric isothermal c...

The article analyzes the modern theory and practice of pipeline transport bituminous oil together with low-viscosity solvent. In addition, a detailed analysis rheological models non-Newtonian fluids is carried out, which establishes number assumptions on rheology model selection algorithm currently in use (limited models, variability coefficient assignment, etc.). Ways their elimination are pro...

Abstract Medicinal herbs have a long history of use in improving human health and curing diseases. Herbal materials are naturally an excellent medicine library because they provide unlimited components with complex chemical structures and a wide range of bioactivities. Herbal materials have thus attracted wide interest of researchers in the identification of the active components and verificati...

MDM2 is a key regulator of the p53 tumor-suppressor protein. Here we study the effect of modifications of a p53 N-terminal fragment on its binding to MDM2, using implicit-solvent MD and MM-GB/SA calculations. We provide interpretation of existing experimental data and predict the effect of mutations on binding. Notably 1) We analyze the effect of regulatory phosphorylations at Ser/Thr residues ...

In this study, we first investigated changes seen in electrical and optical properties of a polymer light-emitting diode due to using different kinds of solvents and their mixture. Two-layer light emitting diodes with organic small molecules doped in a PVK polymer host were fabricated using (i) non-aromatic solvent chloroform with a high evaporation rate; (ii) aromatic solvent chlorobenzene wit...
