Abstract. The impact of molecular level surface chemistry for aerosol water-uptake and droplet growth is not well understood. In this work, spherical, nonporous, monodisperse polystyrene latex (PSL) particles treated with different functional groups are exploited to isolate the effects activation. PSL effectively water insoluble changes in particle may be considered a critical factor initial up...

moisture sorption isotherms are useful in food dehydration, storage and packaging. because of the complex food composition, experimental measurements are necessary for prediction of the isotherms. moisture sorption isotherms of thompson seedless raisins were determined at 30, 40, 50, 60, 70 and 80?c, using the standard static gravimetric method developed by the european cooperation project cost...

In the past it has already been shown that adsorption isotherms of liquid or solid lms are not described completely by the Frenkel Halsey Hill theory. Substrate roughness as well as thermal uctuations have to be taken into account in understanding the adsorption behavior. The inclusion of thermal uctuations into the adsorption theory has already been addressed and proven to provide an explanati...

The detection of genetically modified (GM) materials in food and feed products is a complex multi-step analytical process invoking screening, identification, and often quantification of the genetically modified organisms (GMO) present in a sample. "Combinatory qPCR SYBRGreen screening" (CoSYPS) is a matrix-based approach for determining the presence of GM plant materials in products. The CoSYPS...

Abstract Fractal dimension can be used to the pore surface characterize. For structures in different sizes, calculation models of fractal theory should distinguished due principles gas adsorption experiments. To further study adaptability model for experimental data, author collected shale samples Longmaxi formation from Well JY1, then CO 2 and N provided PSD curves. In addition, dimensions mic...

In this study, Saccharum bengalense(SB) was used as biosorbent for the removal of Mn (II) ions from aqueous solution. The influence of biosorbent dose, time, pH and temperature was investigated in the biosorption process. Studies showed that by increasing pH of the solution, metal removing efficiency of Saccharum bengalensefrom the aqueous environment was enhanced but to a specific extent, ...

Electron beam irradiated sheep wool dosed (0–410) kGy showing good adsorption properties was tested for Cr(III) and Co(II) of higher concentrations. Fitting to ten isotherm models examined as follows: Langmuir, Freundlich, Dubinin-Radushkevich, Temkin, Flory-Huggins, Halsey, Harkins-Jura, Jovanovic, Elovich Redlich-Peterson. Both cations being Lewis acids generate complex salts, such carboxylat...

In the coming years, the frequency of unauthorised genetically modified organisms (GMOs) being present in the European food and feed chain will increase significantly. Therefore, we have developed a strategy to identify unauthorised GMOs containing a pCAMBIA family vector, frequently present in transgenic plants. This integrated approach is performed in two successive steps on Bt rice grains. F...
