“…Metallic and metal oxide nanoparticles are important for these applications due to their features such as tunable optical properties, biocompatibility, feasible surface functionalization and negligible cytotoxicity, etc. [9][10][11][12][13][14][15][16][17][18].…”

In the present work, zinc oxide nanoparticles (ZnO-NPs) were synthesized in the presence of poly(ethylene glycol) which is a biocompatible agent in living systems. The sub-chronic effects of ZnO-NPs were investigated based on biochemical parameters and histological changes applied to Rattus norvegicus. The structural, morphology, and size characterization of nanoparticles were studied by applying techniques as XRD, SEM, FTIR, and TEM. 8-week intraperitoneal injection of ZnO-NPs at a dose of 100 mg/kg leads to significant changes in liver enzymes, malondialdehyde (MDA) content, and tissue histopathological changes. The animal group which was treated with 50 mg/kg of ZnO-NPs presented elevated blood urea nitrogen and creatinine levels, but the liver enzymes and liver histopathology were found to be in normal level. The rats exposed to increasing dose of ZnO-NPs (100 mg/kg) showed necrosis of germinal epithelium and sertoli cells in the seminiferous tubules. The current study clearly demonstrated the dose-dependent toxicity of zinc oxide nanoparticles.

“…This finding is in line with the fact that most nonspherical Cu/CuO x nanostructures are generated by ns-LAL, during which the thermal effect dominates. At a very high fluence of 80 J/cm 2 , a large amount of H 2 gases are generated, enabling the formation of hollow CuO x structures [233]. Fs laser ablation is a "cold" process because of the insufficient electron-phonon relaxation [234], which can significantly inhibit the thermal effect.…”

Diverse nanomaterials, in the forms of carbides, sulfides, oxides, metals, hydroxides, etc., have been synthesized by laser ablation in liquids (LAL) with metal targets as the dominant educts. Many advantages of LAL technique itself and its products have been revealed since 1983 when the first report about LAL was released. Different from traditional wet-chemical synthesis, one unique feature of LAL is its resultant extreme high-temperature and high-pressure local environment for the nucleation and growth of nanomaterials, despite being performed at room temperature. This extreme condition can induce the atomization and ionization of the target materials and liquid molecules to incur different chemical reactions. The laser, liquid, liquid additive, and target can significantly alter the local environment in a broad range. Thus, different phases and shapes of nanomaterials are producible even from the same target. Through directly comparing the products of LAL of 13 kinds of chosen representative metals synthesized under different conditions, this review presents and discusses current understandings, challenging issues, and perspectives related to the diversity of LAL-products, which is willing to promote a deeper investigation and discussion on a clear clarification of the chemical reactions and particle nucleation/growth processes.

“…The obtained d‐spacing value of 0.28 nm for ZnO NPs matches the (002) crystal plane of hexagonal ZnO NPs. The obtained d‐spacing value of 0.13 nm on the NCs is the (−220) crystal plane of CuO NPs [45] …”

Synergistically Augmented ZnO via Cobalt and Copper Simultaneous Doping for Pollutant Reduction

et al. 2023

Continuous electron‐hole transfer and the ability of nanoscale materials to absorb visible light are critical for pollutant catalytic reduction. Cobalt and copper co‐doped ZnO composites were shaped by the sol‐gel solution combustion (SG‐SC) approach. The x‐ray diffraction analysis confirmed the crystalline nature and interstitial doping of copper and cobalt in the zinc oxide lattice and the development of ZnO‐CuO local contact. The PL and DRS‐UV‐vis investigations showed the NCs’ superior charge transfer and considerable redshift (from 3.17 to 2.21 eV) properties over ZnO. TEM and SEM‐EDS analyses confirmed the foam‐type surface morphology, elemental composition, and dopant distribution. The NCs showed greater potency than ZnO NPs in the catalytic reduction reactions of 4‐nitrophenol and methylene blue. Thus, the SG‐SC approach has the potential for industrially scalable catalytic pollutant reduction applications.
