An exfoliation-reassembly-activation (ERA) approach to lithium-ion battery cathode fabrication is introduced, demonstrating that inactive HCoO(2) powder can be converted into a reversible Li(1-x) H(x) CoO(2) thin-film cathode. This strategy circumvents the inherent difficulties often associated with the powder processing of the layered solids typically employed as cathode materials. The delam...

The role of sawdust in the removal of pollutants from textile wastewater has been investigated. The textile wastewater was treated by using sawdust as adsorbent and then filtered. The various physicochemical characteristics of sawdust treated and untreated textile effluent were analyzed. The maximum percent removal of 37% was observed for total suspended solids while minimum removal of 9% for c...

A solid-phase radioiodination technique for wiodophenyl fatty acids using ammonium sulfate is described. The radioiodinations are (I) regioselective, (2) high in yield (95%), (3) short in reaction time (I h) and (4) capable of yielding high specific activity products although at lower yields. Purification is exceptionally simple: a single passage through an ion exchange column to remove unreact...

We report in-situ spectroscopic measurements of the structure and orientation of molecules in the interfacial region between the semi-soluble ionic solid CaF2 (fluorite) and an aqueous phase. This paper integrates a series of new experiments with earlier results to give a comprehensive understanding of this very dynamic interface. We employ the surface specific technique, vibrational sum-freque...

Ion exchange at charged solid-liquid interfaces is central to a broad range of chemical and transport phenomena. Real-time observations of adsorption/desorption at the molecular-scale elucidate exchange reaction pathways. Here we report temporal variation in the distribution of Rb+ species at the muscovite (001)-water interface during exchange with Na+. Time-resolved resonant anomalous X-ray re...

In this study, polystyrene ethylene butylene polystyrene (PSEBS) was functionalized to prepare mono and bipolar ion exchange membranes. In the case of the bipolar membrane, platinum was used as the intermediate layer. NaCl solution of concentration ranging from 5 g/L to 25 g/L was used as the feed solution. A commercially procured ion exchange membrane made of polystyrene divinyl benzene was al...
