“…The diffraction peaks are found to broaden with a decrease in their intensity as copper is doped in NiO, which may be a microstructural strain produced by the introduction of Cu +2 ions in the NiO lattice . The crystallite size was found to increase with the doping of copper in nickel oxide due to the difference in the ionic radii of copper and nickel ions.…”

Nanotechnology research is emerging as cutting-edge technology, and nanoparticles (NPs) and nanocomposites (NCs) have played a significant role in the bioremediation and treatment of polluted water by organic and nonorganic materials. Nanoparticles produced by plant extracts are more stable and biocompatible in comparison with those produced by physical and chemical methods. This research focuses on the synthesis of NiO NPs and Cu–NiO NCs using Phytolacca dodecandra L’Herit (P.d) leaf extract and evaluation of their antioxidant and photocatalytic activities. Cu–NiO NCs were synthesized using 50 mL of 0.1 M nickel(II) nitrate hexahydrate, 10 mL of 0.1 M copper(II) nitrate trihydrate, and 20 mL of leaf extract. The synthesized nanoparticles were characterized by UV–vis, X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), and scanning electron microscopy (SEM) analyses to study the energy band gap, average crystallite size, functional groups, and morphology of the samples, respectively. The UV–vis analysis showed a red shift after copper doping, indicating a decrease in the optical band gap values. FT-IR characterization confirms the presence of various functional groups in samples. Crystallite sizes of the formed particles were obtained to be 14.18 and 16.10 nm from the XRD data for NiO NPs and Cu–NiO NCs, respectively. SEM showed the crystallinity of particles with a cubic structure. The photocatalytic degradation of methylene blue (MB) was found to be 78.3 and 97.8% by NiO NPs and Cu–NiO NCs, respectively. In the antioxidant test, NiO NPs and Cu–NiO NCs prevented the oxidation of 50% of the H2O2 molecules at a concentration of 363.96 and 350.29 μg/mL, respectively. Finally, the synthesized samples showed good photocatalytic and antioxidant activities.

“…Zirconium-based Metal-organic frameworks, such as UiO-66 and UiO-66-NH 2 , can be considered as a practical alternative for designing drug delivery systems since they contain an adjustable cavity size and high compatibility with physiological systems [ 30 – 32 ]. Some of the advantages of using UiO-66-NH 2 include obtaining the benefits of biological adaptability and the ability to attract large amounts of drugs, as well as having control over the drug release [ 32 – 34 ]. According to the recent findings, copper sulfide nanoparticles can treat cancer by destroying cancerous tumors and stimulating the immune system against cancerous cells.…”

“…In addition, the copper sulfide that is sized in a nanometer scale has been observed to display different features than its bulk form and upon being exerted in a controlled manner, they have proved to be safe and antineoplastic. It is also notable that next to directly annihilating the cancer cells, copper compounds cause an enhancement in the immune system to cope with cancer as well [ 34 – 40 ]. In this study, copper sulfide nanoparticles were integrated into the structure of UiO-66-NH 2 and applied in vitro to deliver Oxaliplatin to the colorectal cancer cells.…”

In this work, UiO-66-NH2 was used to prepare a new delivery system by incorporating copper sulfide (CuS) into the pores. The CuS nanoparticles (NPs) were prepared to enhance the anticancer effects of Oxaliplatin (OXA) against colorectal cancer. The oxaliplatin was loaded into CuS@UiO-66-NH2. To characterize and investigate their cytotoxicity effects, powder X-ray diffraction (PXRD), Fourier transformation infrared spectroscopy (FT-IR), Brunauer–Emmett–Teller (BET) analysis, UV-Visible analysis, inductively coupled plasma mass spectrometry (ICP-MS), and MTT assay were considered to be performed. According to the observations, the cytotoxicity of OXA-CuS@UiO-66-NH2 was greater than that of the OXA alone.

“…Recently, the progress of organic solar cells (OSCs) and Si-based solar cells through new materials and technologies has received significant attention but a huge advantage of organic photovoltaic (OPV) technology is its simple architecture, solution processability, low-cost manufacturing, lightweight, semitransparency, and flexibility. − OPV technology is the most suitable for flexible devices that use favorable organic polymers. The mechanical flexibility of these materials makes them compatible with the use of plastic substrates .…”

In this study, P3HT:PC 61 BM was utilized to fabricate flexible organic solar cells (OSCs) on the polyethylene terephthalate substrates under an ambient atmosphere. An efficient electron transport layer (ETL) was employed to achieve a better device performance. The ETL was fabricated by making a nanocomposite from zinc oxide (ZnO) and polyethyleneimine ethoxylated (PEIE). The PEIE doping causes the reduction of work function of ZnO as well as passivates the interface, which ultimately improved the performance of the solar cell. The ZnO device's performance was 0.80%, which was effectively enhanced to 0.95% after the PEIE doping with an increase in the FF and J sc . The ZnO's reduced work function due to PEIE is responsible for easy charge conveyance from the photoactive layer to the cathode, which enhances the FF and J sc values. Besides, the flexible OSCs with the ZnO:PEIE ETL demonstrate more improvements in the mechanical property than with ZnO. The device with the ZnO:PEIE ETL sustained around 80% of its original power conversion efficiency (PCE) after 800 bending cycles. Thus, this study can contribute to the future large-scale manufacturing of flexible OSCs by using the ZnO:PEIE ETL.
