Light-responsive molecules have seen a major advance in modulating biological functions recent years. Especially photoswitches are highly attractive building blocks due to the reversible nature of their light-mediated reactivity. They frequently used affect both properties small bioactive compounds and biomacromolecules if incorporated suitably. Despite success plethora applications, only limit...
Background and Purpose:Organic dyes with a complex structure are often toxic, carcinogenic, mutagenic, non-biodegradation and stable in the environment and if released to the environment without treatment can endanger the environment and human health. The aim was to evaluate the performance nanoscalezero-valent iron (NZVI) in the removal of dye acid red 18 (AR18) from aqueous solutions. Materia...
Hurwitz, Charles (Veterans Administration Hospital, Albany, N.Y.), Catherine B. Braun, and Richard A. Peabody. Washing bacteria by centrifugation through a water-immiscible layer of silicones. J. Bacteriol. 90:1692-1695. 1965.-A method is described which enables the separation of cells from aqueous suspension without altering the internal aqueous environment of the cells. The method consists of...
Background and Aim: Copper ions, due to forming complexes with organic and mineral compounds, can have worrying effects on health and environment. In the present study, the effect of powdered magnetic carbon activated by iron-oxide nanoparticles in removing of CU (V; II) from aqueous solutions was assessed. Materials and Methods: This experimental study aimed at determining the effect of pow...
Membrane formation by amphipathic mixtures in aqueous environments is central to eukaryotic biology. Formation of aqueous compartments enclosed by membranes is of immense importance in designing liposomal systems for pharmaceutical applications. It is also continuously controlled within the dynamic environment of a living cell and, during cell division. In spite of over four decades of research...
