TLDR
An overview of silver nanoparticle preparation by physical, chemical, and biological synthesis is presented to reflect on the current state and future prospects, especially the potentials and limitations of the above mentioned techniques for industries.Abstract:
Silver nanoparticles (NPs) have been the subjects of researchers because of their unique properties (e.g., size and shape depending optical, antimicrobial, and electrical properties). A variety of preparation techniques have been reported for the synthesis of silver NPs; notable examples include, laser ablation, gamma irradiation, electron irradiation, chemical reduction, photochemical methods, microwave processing, and biological synthetic methods. This review presents an overview of silver nanoparticle preparation by physical, chemical, and biological synthesis. The aim of this review article is, therefore, to reflect on the current state and future prospects, especially the potentials and limitations of the above mentioned techniques for industries.read more

Abstract: This study involves the fabrication of green-based superhydrophobic coatings, which can be applied to a surface via a simple spraying technique. The coating formulation is green as it utilizes silica extracted from rice husks (RHA) and silver particles reduced and capped by cabbage (CRS), both of which are readily available and environmentally-benign. 12.5 wt% loading of the RHA in the coating was found to yield the best superhydrophobic behavior via contact angle measurement. By further introducing CRS, which induces repulsive forces preventing particle agglomeration, the resulting RHA/CRS-coated surfaces exhibited better anti-wetting behavior and improved stability and durability. In addition, the coating was also shown to possess self-cleaning property, pH resistance, and insensitivity to any touches. All of these reveal the potential of the green-formulated RHA/CRS coating as a cheaper and friendlier alternative in the quest for superhydrophobicity.
