we have used lithium aluminum hydroxide reducing method of silver nitrate to prepare heterogeneous silver-silica nanocomposite particles with thiol and amino groups serving to bind the ag nanoparticles to the surfaces of the sio2 nanoparticles. we examined products of these reductions using ftir, sem, xrd and uv-vis. spectroscopy. the sio2 nanoparticles had diameters ranging from 70 to 90 nm; t...

Removal of perchlorate using either acid-washed zero-valent aluminum or aluminum hydroxide was studied in batch reactors under ambient temperature and pressure. Approximately 90-95% of perchlorate was removed within 24h in the presence of 35 g L(-1) aluminum at acidic pH (4.5+/-0.2). Although aluminum is a strong reductant, this study indicated no explicit evidence to support perchlorate reduct...

This study was designed to determine the effects of an aluminum hydroxide antacid and a calcium carbonate antacid on the bioavailability of ciprofloxacin (Cipro). Cipro (750 mg) was administered orally to 12 healthy volunteers in a three-way randomized crossover design. The three treatments included Cipro alone, four 850-mg calcium carbonate tablets taken 5 min before Cipro, and three 600-mg al...

In this study, Flake-like magnesium hydroxide (Mg(OH)2) and cubic-like aluminum hydroxide (Al(OH)3) nanostructures were synthesized via a simple co-precipitation method at relatively low temperature. Chemical properties and surface morphology of the magnesium hydroxide and aluminum hydroxide were characterized by X-ray diffraction analysis (XRD), scanning electron microscopy image (SEM), transm...

objective(s): the role of aluminum (al) in the pathogenesis of neurodegenerative diseases has been implicated in several studies. however, the exact mechanisms of cytotoxic effects of al have not been elucidated yet. the aim of this study was to investigate the effect of l-type calcium channel antagonist, nimodipine (nm), and lithium chloride (licl) on al-induced toxicity in pc12 cells. materia...

This study was designed to determine the influence of aluminum hydroxide and famotidine on the bioavailability of tosufloxacin. Coadministration of aluminum hydroxide reduced the bioavailability of tosufloxacin by 31.6% (P < 0.05). Famotidine did not alter tosufloxacin absorption. To avoid potential treatment failures, the concurrent use of tosufloxacin and aluminum hydroxide should be avoided ...

Mice immunized with a subcutaneous protocol combining killed para­ sites and aluminum hydroxide gel exhibited significant resistance against subsequent challenge with Leishmania donovani promastigotes. Protec­ tion was greatest using 25 mg of aluminum hydroxide per injection. Resis­ tance elicited by this killed parasite and aluminum hydroxide protocol was as effective on day 14 as that provide...

Electrodeposited aluminum films and template-synthesized aluminum nanorods are examined as negative electrodes for lithium-ion batteries. The lithium-aluminum alloying reaction is observed electrochemically with cyclic voltammetry and galvanostatic cycling in lithium half-cells. The electrodeposition reaction is shown to have high faradaic efficiency, and electrodeposited aluminum films reach t...
