Photocatalytic degradation proficiency was studied for bromothymol blue dye. Phytochemicals-coated Nickel Oxide nanoparticles demonstrated antibacterial properties against bacteria (gram negative strain of E. coli, Pseudomonas spp. and gram positive strain of Bacillus spp.) by showing highest zone of inhibition (19 mm, 22 mm, 15 mm).the antioxidant activity of the synthesized nanoparticles were also examined and the result show that the fabricated nanoparticles exhibited significant radical scavenging activity.

The silver nanoparticles are synthesized by the green method using Salix semi-solid extract. Fresh leaves are prepared in a semi-solid extract form that retains active substances and can be preserved for a long time. The parameters of the synthesis process are optimized by examining the effects of pH, Salix semi-solid extract concentrations of extract and AgNO3 concentrations through the UV-Vis absorption spectrum of synthetic particulate solutions.

In this study, Zinc oxide nanoparticles (ZnO NPs) were green synthesized using Piper chaudocanum L. (PC) leaf extract by sol-gel method and used as an adsorbent for the removal of Pb (II) ions from aqueous solution. The synthesized ZnO NPs were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), Fourier transform infrared spectroscopy (FTIR), Ultraviolet - visible spectroscopy (UV-Vis) and Brunauer - Emmet - Teller (BET).

The potential isolation of bio-active polysaccharides from bay tree pruning waste was studied using sequential subcritical water extraction using different time-temperature combinations. The extracted polysaccharides were highly enriched in pectins while preserving their high molecular mass (10–100 kDa), presenting ideal properties for its application as additive in food packaging.
