pb and cd in water samples were determined by cloud point extraction (cpe) with sodiumdiethyldithiocarbamate (ddtc) as the chelating agent and octylphenoxypolyethanl (triton x-114) asthe surfactant prior to flame atomic absorption spectrometry (faas) determination. the main factorsof affecting the extraction and detection processes were optimized. the preconcentration of 10 ml ofstandard soluti...

By using Triton X-114 as structure-director and weak binding stabilizer, ultrathin Au, Pd and Pt nanowires are synthesized in seconds by reduction of inorganic metal precursors with KBH(4) in aqueous phase. The nanowires show high catalytic activity and long-term stability toward electrooxidation of alcohols.

The present work compares six biochemical methods for extraction of lipids from human serum. Although some organic solvents were good lipid extractors, they precipitated most of the total proteins and albumin. On the other hand, methodologies using Triton X-114 and silica were efficient for extraction of lipids, while sparing the protein fraction.

Cilia were isolated from Tetrahymena thermophila, extracted with Triton X-114, and the detergent-soluble membrane + matrix proteins separated into Triton X-114 aqueous and detergent phases. The aqueous phase polypeptides include a high molecular mass polypeptide previously identified as a membrane dynein, detergent-soluble ct and 13 tubulins, and numerous polypeptides distinct from those found ...

The cortical microtubules determine how cellulose microfibrils are deposited in the plant cell wall and are thus important for the control of cell expansion. To understand how microtubules can control microfibril deposition, the components that link the microtubules to the plasma membrane (PM) of plant cells must be isolated. To obtain information on the properties of the tubulin-membrane assoc...
