Impact of industrial air pollution on the quality of atmospheric water production.

The atmospheric water generator (AWG) is a commercially available device that produces water from the air in large volumes over short times. This method can be applied in most regions of the world to solve chronic and acute drinking water scarcity. However, knowledge of the effects of air chemical composition on AWG-produced water quality is still very limited.

Aqueous stability of alumina and silica perhydrate hydrogels: experiments and computations.

Alumina and silica perhydrate hydrogels were synthesized. Raman spectroscopy and solid (27)Al MAS NMR confirmed alumina perhydrate formation. Thermal and aqueous stability of alumina and silica perhydrates was studied, and they showed exceptionally high stabilities.

Zinc dioxide nanoparticulates: a hydrogen peroxide source at moderate pH.

Solid peroxides are a convenient source of hydrogen peroxide, which once released can be readily converted to active oxygen species or to dissolved dioxygen. A zinc peroxide nanodispersion was synthesized and characterized, and its solubility was determined as a function of pH and temperature. We show that zinc peroxide is much more stable in aqueous solutions compared to calcium and magnesium peroxides and that it retains its peroxide content down to pH 6.
