Surface modification of nanoparticles is often utilized to tailor the interfacial properties in dielectric nanocomposites. Introducing different functional groups nanoparticles’ surface may induce localized states (traps) that can enhance performance material depending on their density and energy levels. Furthermore, filler affect dispersion quality crystallization nanocomposites which ultimate...

Abstract Recent progress in macromolecular reaction engineering has enabled the synthesis of sequence‐controlled polymers. The advent olefin block copolymers (OBCs) via chain shuttling polymerization ethylene with α‐olefins opened new horizons for polyolefins having a dual character thermoplastics and elastomers. Nevertheless, use two catalysts different comonomer selectivities agent, dragging ...

A series of N-acetyl-O-(ω-alkenyl)-L-tyrosine ethyl esters were synthesized by the reaction of vinyl bromides (4-bromo-1-butene, 6-bromo-1-hexene, 8-bromo-1-octene and 10-bromo-1-decene) with N-acetyl-L-tyrosine ethyl ester. 1H NMR, elemental analysis, FT-IR, and mass spectra were performed for these N-acetyl-O-(ω-alkenyl)-L-tyrosine ethyl esters. The novel titanium complex can catalyze the cop...

Halogenated gomisin J (a derivative of lignan compound), represented by the bromine derivative 1506 [(6R, 7S, S-biar)-4,9-dibromo-3,10-dihydroxy-1,2,11,12-tetramethoxy-6, 7-dimethyl-5,6,7,8- tetrahydrodibenzo[a,c]cyclo-octene], was found to be a potent inhibitor of the cytopathic effects of human immunodeficiency virus type 1 (HIV-1) on MT-4 human T cells (50% effective dose, 0.1 to 0.5 microM)...

an analytical equation of state (eos) developed by ihm-song-mason (ism) has been applied tocalculate some thermophysical properties of molten polymers including poly (1-octene) (po), poly (vinylmethyl ether) (pvme), poly (vinyl chloride) (pvc), and poly (styrene) (ps). three temperature-dependentparameters of the ism eos have been determined based on the alternative scaling constants, dispersiv...

Graphene oxide (GO) and N-doped graphene [(N)G] graphenes were submitted to H2 glow discharge under different regimes, in both the negative positive column plasma regions. The resulted catalysts fully characterized using several techniques such as Raman, DRIFT XPS spectroscopy, powder X-ray diffraction, pulse chemisorption H2-, CO2- NH3-TPD experiments. Density functional theory calculations pe...
