Iron oxide nanoparticle formation in DES was studied in situ across multiple length scales. Initial chloride-containing iron complexes react to form oxygen-rich species which precipitate. Morphology and growth time are defined by solvent composition.

The application of calorimetric principles to the determination of phosphorus is especially desirable in view of the long drawn out and laborious gravimetric method now customarily employed. The accuracy of calorimetric methods, the ease with which most calorimetric procedures are carried on and their employment where only small amounts of material are available for analysis would make a reliab...

This paper reports a new class of periodic banding Fe(OH) 3 precipitate through reaction–diffusion–reaction (RDR) processes in agarose gel sandwiched between two metal rods (Ti and Fe) with cyclic alternating voltages. In the RDR processes, electrochemical reactions at to generate reactant ions, diffusion ions influenced by electric field gel, form precipitates were coupled bands cathode side. ...

Poly-o-anisidine Sn(IV) arsenophosphate is a newly synthesized nanocomposite material and has been characterized on the basis of its chemical composition, ion exchange capacity, TGA-DTA, FTIR, X-RAY, SEM, and TEM studies. On the basis of distribution studies, the exchanger was found to be highly selective for lead that is an environmental pollutant. For the detection of lead in water a heteroge...

Mutant, unstable hemoglobins precipitate as Heinz bodies in circulating red blood cells resulting in their premature hemolysis. We stress that generally these hemoglobins contain amino acid substitutions in the beta-chain of globin near the heme pocket, and demonstrate that heme binding suffers thereby. Four genetically unstable hemoglobins lost roughly half their heme content while precipitati...

The regioselective ring opening of styrene oxide using elemental iodine and bromine in the presence of disulfides as new catalysts was studied. The conductivity titration and UV spectroscopy were used to study the interaction of iodine with these catalysts. The results indicate that disulfide 11 is efficient in polyiodide formation, and can catalyze this reaction in excellent yield and high reg...

Abstract The temporal dependence of $$\gamma '$$ γ ′ dissolution in the polycrystalline Ni-base superalloy RR1000 has been studied with implications to thermo-mechanical processing. A resistivity-based method using an electro-thermal mechanical testing (ETMT), which ove...
