Radiation synthesis of copper sulphide/poly(vinyl alcohol) nanocomposites films: an efficient and reusable catalyst for p-nitrophenol reduction

Antibacterial and antibiofilm activities of silver-decorated zinc ferrite nanoparticles synthesized by a gamma irradiation-coupled sol–gel method against some pathogenic bacteria from medical operating room surfaces

“…32 Radiation-induced synthetic methods and especially those that allow the interaction of gamma rays with solutions may have a fantastic potential to ght with approved plans to increase the purposes in terms of synthesis, control in the size, shape, eco-friendly of starting materials, and decreases the production of the toxic materials, overall these benets are eco-friendly. 33,34 Overall, this paper reports, for the rst time, the gamma irradiation-assisted synthesis of Ag-decorated ZFO NPs (Ag@ZFO). Aerwards, the pure ZFO NPs and Ag-decorated ZFO NPs were tested against pathogenic strains from medical operating room surfaces (surgical rooms).…”

Incorporation of copper nanoparticles into the nitrogen‐doped carbon derived from nitrile functionalized ionic liquid as the non‐precious heterogeneous catalytic system toward nitro compounds reduction reaction, a first principle calculation

“…Nitro reduction reaction is one of the most substantial chemical reactions employed in the industry because of the aromatic amines that are used as intermediates in the synthesis of important and diverse materials, such as dyes, pharmaceuticals, antioxidants, polymers, pesticides, and many of the precursors needed in agriculture 31‐33 . Different types of transition metals, such as Palladium (Pd), Cobalt (Co), Nickel (Ni), Silver (Ag), Iron (Fe), and Copper (Cu), have exhibited an excellent efficiency and selectivity towards nitroarenes reduction reaction 34‐36 . Among them, copper nanoparticles have attracted the most attention from researchers due to their low toxicity, better economical aspect compared to other metals (such as Pd), and their availability.…”

“…[31][32][33] Different types of transition metals, such as Palladium (Pd), Cobalt (Co), Nickel (Ni), Silver (Ag), Iron (Fe), and Copper (Cu), have exhibited an excellent efficiency and selectivity towards nitroarenes reduction reaction. [34][35][36] Among them, copper nanoparticles have attracted the most attention from researchers due to their low toxicity, better economical aspect compared to other metals (such as Pd), and their availability. As most of the catalytic process occurs on the surface of the metals, the high ratio of their surface area to their size affects the efficiency and reactivity of NPs.…”

Fabrication of a Lignin-Copper Sulfide-Incorporated PVA Hydrogel with Near-Infrared-Activated Photothermal/Photodynamic/Peroxidase-like Performance for Combating Bacteria and Biofilms

“…26 The XRD pattern of PVA shows two broad diffraction peaks at 2θ values around 19.42 and 40.70°, corresponding to the (101) and (220) planes of semicrystalline PVA. 27 For LS-CuS@PVA, the weak diffraction peaks located at 29.34, 32.88, and 48.01°correspond to the (102), (103), and (110) planes of CuS. The FT-IR spectra of LS, LS-CuS nanocomposites, PVA, and LS-CuS@PVA are shown in Figure 2b.…”
