Surfactant-assisted microwave processing of ZnO particles: a simple way for designing the surface-to-bulk defect ratio and improving photo(electro)catalytic properties.

ZnO nanopowders were produced using microwave processing of a precipitate and applied as a photoanode for photoelectrochemical water splitting. Two different surfactants, cetyltrimethylammonium bromide (CTAB) as the cationic and Pluronic F127 as the non-ionic one, were employed to adjust the surface-to-bulk defect ratio in the ZnO crystal structure and further to modify the photo(electro)catalytic activity of the ZnO photoanode. The crystal structure, morphological, textural, optical and photo(electro)catalytic properties of ZnO particles were studied in detail to explain the profound effects of the surfactants on the photoanode activity.

Depression in parents of children with cerebral palsy in Bosnia and Herzegovina.

The aim of the research is to examine depression in parents of children with cerebral palsy, with hypothesis to have more depressive symptom among mothers of children with cerebral palsy. The sample of examinees (between 23 and 62 age) was used in this research. The first subsample of examinees (N=23) was made of mothers (average 33±5.
