We study the formation of columnar structures of uniaxial dipoles in an external magnetic field both experimentally and theoretically. By applying an external magnetic field parallel to a thin layer of a magnetorheological fluid, we manipulate a single initial cluster of suspended colloidal particles. We find that the cluster breaks up into columns that have approximately uniform widths and int...

The scattering of visible light by hexagonal-shaped column containing densely packed inclusions is simulated by a combination of ray-tracing and Monte Carlo techniques. While the ray tracing program takes care of the individual reflection and refraction events at the outer boundary of the particle, the Monte Carlo routine simulates internal scattering processes. A dense-medium light-scattering ...

For building a sustainable fermentation process, it is essential to reduce dependence on natural resources and lower the amount of pollution that created. The reuse agro-industrial wastewater after possible treatment leads achievement these goals concurrently. This study investigates production citric acid cellulase enzyme by A. niger cultivated in olive mill (OMW) using loofa sponge-packed col...

The applicability of packed and open columns for supercritical fluid chromatography using pure carbon dioxide for the elution of a number of selected test components was investigated. It is shown that the number of solutes that can be eluted as symmetrical peaks is much larger in open-tubular capillary supercritical fluid chromatography. For strong hydrogen donors and acceptors, however, poor p...

The detailed glycan structural analysis of glycoprotein is amenable to glycopeptide enrichment. Here, we develop a simple, effective and economical approach to enrich glycopeptides from proteolytically digested peptide mixtures by chromatographic column packed with graphite carbon and activated charcoal (G/A-column). Glycopeptide from ovalbumin was efficiently enriched by homemade G/A-column us...
