Competitive hybridization, at the surface and in the bulk, lowers the sensitivity of DNA chips. Competitive surface hybridization occurs when different targets can hybridize with the same probe. Competitive bulk hybridization takes place when the targets can hybridize with free complementary chains in the solution. The effects of competitive hybridization on the thermodynamically attainable per...

Polyaniline titanotungstate (PATiW) was synthesized by the sol-gel method. Adsorption isotherm studies of Cs from aqueous solution are described. Elemental Composition, chemical solubility, ion-exchange capacity (IEC) and pH titration are studied. Distribution coefficients (Kd) for ten metal ions have been determined. It was found that the polyaniline titanotungstate has high affinity and high ...

the hydrogenation characterizations of the hydrogen storage alloy mmni4.22co0.48mn0.15al0.15 (mm= mischmetal), and the effect of hydrogenation/dehydrogenation (h/d) cycling on its structural and morphological properties are investigated. the results indicate that after several h/d cycles the alloy was pulverized into fine particles, but it kept its hexagonal cacu5-type structure. the pressure-c...

Corn distillers dried grains with solubles (DDGS) has high feed value due to its nutritive contents. The ratio of wet distillers grains (WDG) and condensed distillers solubles (CDS) added during the production ...

By forcing an aqueous solution of N-lauroylsarcosine sodium salt and 8-anilino-1-naphthalenesulfonic acid ammonium salt in a hydrophobic nanoporous silica gel, the external work can be largely dissipated due to the amplified capillary effect. The sorption isotherm curve is two-staged, and the height and the width of stage-I infiltration plateau can be adjusted separately by controlling the liqu...

This study investigates moisture uptake and diffusion mechanisms in thermoset particle-filled composites for anchor applications. Two epoxy-based with low inorganic filler content one vinyl ester-based high were studied. Material characterization revealed particle size distribution, density, the occurrence of pores, composition. Moisture was monitored at different temperatures, relative humidit...

In chromatographic separations involving elutes with large differences in the molecular size, the adsorption saturation capacities of the elutes may differ because of the differences in the degree of size exclusion. With uneven saturation capacities, isotherm crossovers may occur, which often results in selectivity reversal. In this work, a new multicomponent isotherm has been developed for thi...
