Some radiation shielding parameters as mass attenuation coefficient (MAC), linear attenuation coefficient (LAC), half value layer (HVL), tenth layer value (TVL...

Barium borosilicate glasses (BaO–SiO2–B2O3) with the addition of 5–25 wt% bismuth oxide as additive (equivalent to 1.23–5.88 mol% of Bi2O3 in glasses) were prepared for using as a sealant for planar solid oxide fuel cells. The effect of Bi2O3 addition on thermal properties, structure, crysta...

Cerium doped barium borate glasses were prepared in the BaO-B2O3 system. The effect of CeO2 admixture on thermal stability and structure of the glass was developed. Thermoluminescence (TL) and optically stimulated luminescence (OSL) properties, such as glow curves, linearity of dose-response and...

Publisher SummaryThis chapter illustrates assay, purification, and properties of carboxylmethyl esterase of bacterial chemotaxis. Methylation of a set of transmembrane proteins, originally termed methyl-accepting chemotaxis proteins (MCPs) and now known to be receptors, play a central role in ba...

S-Methyl methanethiosulfonate (MMTS) is used in experimental biochemistry for alkylating thiol groups of protein cysteines. Its applications include mainly trapping of natural thiol-disulfide states of redox-sensitive proteins and proteins which have undergone S-nitrosylation. The reagent can al...

A formulation containing 95% delmadinone acetate was compressed at three different pressures. These pressures resulted in a pellet density difference of 19%. In vivo dissolution profiles were determined for five lots of pellets. The pellets were implanted subcutaneously in rats, removed periodic...

Microbial transformation of chlormadinone acetate to delmadinone acetate was investigated using free and immobilized cells of Arthrobacter simplex ATCC 6946 and Bacillus sphaericus ATCC 13805 in liquid–liquid biphasic system and a liposomal medium. For liquid–liquid biphasic system, n-decane, ...

A 1:1 complex of Lanthanide-substituted Lindqvist-type oxo-nitrosyl polymolybdate [NBu4][La(CH3OH)2(DCU)NO3{Mo5O13(OMe)4(NO)}]·CH3OH (1) has been successfully synthesized by a one-pot self-assembly process of hydroxylamine hydrochloride with octamolybdate, DCC and La(NO3)3 in methanol under mil...

The effect of magnesium acrylate (MgMA) on the interfacial compatibility and shape memory behavior of ethylene propylene diene monomer (EPDM)/polypropylene (PP) thermoplastic vulcanizates (TPVs) prepared through peroxide-induced dynamic vulcanization was investigated in this paper. MgMA could re...

Organic coating has been widely used to protect all kinds of corrosion of iron historic and cultural relics, while what’s the most commonly used is not very desirable in its durability, mechanical properties and hydrophobicity. In order to improve these limitations, a novel polyurethane acrylat...

This study reports the characterization of disperse red 1 acrylate compound by spectral techniques and quantum chemical calculations. The spectroscopic properties were analyzed by FT-IR, UV–vis, 1H NMR and 13C NMR techniques. FT-IR spectrum in solid state was recorded in the region 4000–400 cm...

Silica that originated from the calcination of rice husks, which is a source of biomass silicon, was added as a reinforcing agent to waterborne polyacrylate wood coatings to improve their coating performance, and especially their mechanical properties. The morphology of the rice-husk ash, aggreg...

A novel solid–solid phase change materials, namely, cellulose acrylate-g-poly (n-alkyl acrylate) (CA-g-PAn) (n = 14, 16 and 18) were successfully synthesized by free radical polymerization in N, N-dimethylacetamide (DMAc). The successful grafting was confirmed by fourier transform infrared spec...

Smart bio-based shape memory polymers with high performance and fast response have the exciting potential to meet the growing need in biomedical applications. In this study, novel fast response UV-curable shape memory polyurethane acrylates (SMPUAs) comprising polycaprolactone diols (PCL-Diol), ...

A well-defined fluorine-containing copolymer with pendant epoxy groups, poly(2,2,3,4,4,4-hexafluorobutyl methacrylate-block-glycidyl methacrylate) (PHFBMA-b-PGMA), was prepared by sequential atom transfer radical polymerization (ATRP). The amphiphilic copolymer PHFBMA-b-PGMA(OH) with pendant hyd...

Magnetic non-porous hydrophilic poly(2-hydroxyethyl methacrylate-co-glycidyl methacrylate) microspheres prepared by the dispersion polymerization and modified with iminodiacetic acid (IDA) were employed for the IMAC separation of phosphopeptides. Fe3+ and Ga3+ ions immobilized on IDA-modified ma...

Two new polymerizable surfactants (surfmers), (11-acryloyloxyundecyl)dimethylethylammonium bromide (ethyl surfmer) and (11-acryloyloxyundecyl)dimethyl(2-hydroxyethyl)ammonium bromide (hydroxyethyl surfmer), were synthesized and characterized. The binary phase diagrams of both surfmer/water syste...

A series of ammonium-diol and -triol ionic liquid (IL) monomers were synthesized and used in step-growth polymerization with the commercial di-isocyanate monomer, toluene-di-isocyanate (TDI), in the presence of free ammonium IL to form new curable ammonium-based polymerized ionic liquid/ionic li...

Hydrogen bonds are strong intermolecular interactions, which are very important in molecular aggregation and new phase formation. Three long-chain quaternary ammonium surfactants, N,N-diethyl-N-(2-hydroxyethyl)-N-octadecylammonium bromide with one hydroxyl group, N-ethyl-N,N-bis (2-hydroxyethyl)...
