The most promising technologies to remove perchlorate from water are ion exchange and biological reduction. Although successful, ion exchange only separates perchlorate from water; it does not eliminate it from the environment. The waste streams from these systems contain the caustic or saline regenerant solutions used in the process as well as high levels of perchlorate. Biological reduction c...

We have introduced a selective synthesis of tertiary amines using alkyl halide and ammonium salts as the amine sources in water. This green process has outstanding superiorities, such as being eco-friendly, possessing ammonium salts, and using water as a green solvent in the absence of organic ligands or catalysts. It is worth mentioning that the presence of t-Butyl alcohol and potassi...

 Preparation of 2-Chlorobenzonitrile, and benzonitrile are reported here from the corresponding 2-Chlorobenzaldehyde and benzaldehyde by the reaction of ammonium hydroxide/VPO titania, VPO bulk (...

Ammonium glycolate combustion was used to synthesize SrZr0.95Y0.05O3−x powders. Soluble metal-glycolate complexes, detected by infrared spectroscopy, were formed with Y+3 and Zr+4, which maintain atomic level mixing of metal cations with glycolic acid. Sr+2/glycolic acid mixtures did not form glycolate complexes. Temperature-programmed reaction studies showed that only precursor solutions with ...

This article presents the first systematic study of the effect of Relative Humidity (RH) on the water content and hydroxide ion conductivity of quaternary ammonium-based Alkaline Anion-Exchange Membranes (AAEMs). These AAEMs have been developed specifically for application in alkaline membrane fuel cells, where conductivities of >0.01 S cm(-1) are mandatory. When fully hydrated, an ETFE-based r...

We report a facile new route for the synthesis of self-crosslinked anion exchange membranes (AEM) without the need for any crosslinkers or catalysts. The soluble copolymers bearing flexible side chains, with alkene pendant groups, were synthesized via the Menshutkin reaction. The crosslinked derivatives were then prepared by the thermal crosslinking of the unsaturated side chains during the mem...

The title compound, (NH(4))(2)Cd(3)(SO(4))(3)(OH)(2)(H(2)O)(2), has been obtained serendipitously. It is isotypic with the heavier alkali analogues M(2)Cd(3)(SO(4))(3)(OH)(2)(H(2)O)(2) (M = K, Rb, Cs). The structure contains two Cd(2+) ions, one in a general position and one with site symmetry m. The former Cd(2+) ion is coordinated by three O atoms of three SO(4) groups, two hydroxide O atoms ...

Vaccination of mice with Mycobacterium bovis culture filtrate proteins (CFP), prepared in a variety of adjuvants (aluminum hydroxide, Quil-A, and dimethyldioctyldecyl ammonium bromide [DDA]), provided significant protection against an aerosol challenge of virulent M. bovis. Additionally, vaccination with CFP in DDA or Quil-A did not sensitize mice to M. bovis purified protein derivative.
