Wastewater management has a direct impact on the supply of drinking water. New cutting-edge technologies are crucial to the ever-growing demand for tailored solutions for pollutant removal, but these pollutants first need to be detected. Traditional techniques are costly and are no longer competitive in the wastewater cleaning market. One sustainab...

The enhanced thermal and chemical stability of Zinc oxide-based materials make them excellent candidates for the removal of odor-producing pollutants and compounds. The zinc salt of ricinoleic acid, commonly known as zinc ricinoleate, is viewed as the top performer. This article describes an innovative two-step synthesis of zinc ricinoleate, where...

One of the major obstacles to the reuse of recycled plastic materials is the emanation of after-process odors from recycled polymers and composites. Typically, recycled polymers are blended with an off-odor adsorbent additive in the recycling chain to eliminate these smells.

Meeting global water quality standards is a real challenge to ensure that food crops and livestock are fit for consumption, as well as for human health in general.

For several decades additives have been incorporated into polymeric systems to improve desirable properties, and eliminate undesirable properties. When added to a polyethylene film, the additives migrate to the films' surface and their concentration decreases; over time the additive’s effect desists. To solve this problem, efficient methods for ext...

Antifog (AF) agents are chemicals that prevent the condensation of water as small droplets on hydrophobic surfaces which resemble fog. Antifogs function by minimizing the water surface energy, thus resulting in a continuous film of water rather than single droplets.
