reducing co2 emission and lowering the concentration of greenhouse gases in the atmosphere has quickly become one of the most urgent environmental issues. while a variety of technologies and methods have been developed, the separation of co2 from gas streams is still a critical issue. apart from establishing new techniques, the exploration of membrane materials with high separation performance ...

Objective: The present study was aimed to develop a high performance liquid chromatographic method for simultaneous estimation of curcumin and silibinin and to implement the developed method for the estimation of curcumin and silibinin encapsulated in polymeric nanoparticles. Methods: Method development for simultaneous estimation of curcumin and silibinin was performed using various solvent, b...

2 There has been a wealth of recent interest in proteomics, which involves the global analysis of protein expression and function. Identification of complex protein mixtures is a difficult process that can first involve, for example, two-dimensional gel electrophoresis to resolve individual proteins. These separated proteins can then be hydrolysed with enzymes such as trypsin to their constitue...

this paper focuses on using the recently developed extended finite element model for buckling analysis of edge cracked columns under concentric axial load. the effect of crack depth and its location on the carrying capacity of columns is studied. the effect of different boundary conditions is also investigated. numerical examples are offered to show the efficiency and effectiveness of the propo...

We carried out the mechanochemical polymerization of methacryloyl derivatives of acetoaminophen and 5-fluorouracil in the presence of lactose. The reaction proceeded readily and the polymeric prodrugs were quantitatively produced. This method produces powdered polymeric prodrugs in which fine particles of lactose are homogeneously dispersed, since the reaction proceeds quantitatively through a ...

Facile labeling of oligosaccharides (acidic and neutral) in a nonselective manner was achieved with highly fluorescent anthranilic acid (AA, 2-aminobenzoic acid) (more than twice the intensity of 2-aminobenzamide, AB) for specific detection at very high sensitivity. Quantitative labeling in acetate-borate buffered methanol (approximately pH 5.0) at 80 degreesC for 60 min resulted in negligible ...

in this research, mesoporous silica was applied as the host of corrosion inhibitor (molybdate). the loaded mesoporous silica was dispersed in an epoxy matrix. the composite was then coated on the mild steel plate. results showed that the corrosion resistance of the scratched epoxy/mesoporous silica loaded by molybdate was better than the one without molybdate or neat epoxy. on the other hand, e...

Preparation and uses of quinaldinium dichromate and its polymeric analogue poly (2- vinylquinolinium) dichromate as the new monomeric and polymeric oxochromium-amine complex reagents for oxidizing variousorganic compounds, with emphasis on the latter, are described

nowadays, developements in nanotechnology have leeds an increased application of this newborn technology in cancer treatment. in this study, a stabilized micelle was developed to load hpd in order to be used in photodynamic treatment of cancer in an animal model. to construct micelles, pluronic p-105 was used and stabilized to encapsulate hpd . this process includes a 24 h polymerization in whi...

Graft copolymer composed hyaluronic acid (HA) and poly(D,L-lactide-co-glycolide) (PLGA) (HAgLG) was synthesized for antitumor targeting via CD44 receptor of tumor cells. The carboxylic end of PLGA was conjugated with hexamethylenediamine (HMDA) to have amine end group in the end of chain (PLGA-amine). PLGA-amine was coupled with carboxylic acid of HA. Self-assembled polymeric micelles of HAgLG ...
