This research investigates the effect of cobalt precursor and calcination time on the morphology and catalytic activity of Co3O4 films in the oxygen evolution reaction (OER). Co3O4 films with porous flower-like nanostructures were obtained using cobalt nitrate as a cobalt precursor, while cobalt chlorides were used to produce porous nanoneedle structures Co3O4 film.

Synthesis, characterization, and antimicrobial evaluation of polyvinylalcohol-osthol composite films
Although poly-vinyl alcohol (PVA) has certain mechanical drawbacks such as a weak barrier, it has widely been used in food packaging over the last many years. To increase the suitability of PVA (C2H4O)n and render it ideal for food packaging, a diversity of studies have already been carried out. In the below-mentioned script, we, for the first time, report the use of natural product osthol in making a new composite with PVA for enhancing thermal, physicochemical, and antimicrobial properties.
