Halomethanesulfonic acids (HMSAs) are recently discovered polar disinfection byproducts without commercially available reference materials. To allow for their accurate quantification, we successfully synthesized standards for the four presumably most prevalent HMSA congeners: chloromethanesulfonic acid, bromomethanesulfonic acid, dichloromethanesulfonic acid, and bromochloromethanesulfonic

Nanostructuring of semiconductor films offers the potential means for producing photoelectrodes with improved minority charge carrier collection. Crucial to the effective operation of the photoelectrode is also the choice of a suitable electrolyte. The behaviour of the nanostructured WO(3) photoanodes
