We demonstrated the localized surface plasmon resonance (LSPR) effect of Ni nanoparticles (NiNPs) on the performance of dye-sensitized solar cells (DSSCs). Our study revealed that NiNPs in a conventional I(-)/I3(-) electrolyte (NiNPs@I(-)/I3(-)) increased the net optical absorption of a N719 dye over a broad wavelength range by LSPR, and concurrently improved the power conversion efficiency (PC...

Nickel compounds are widely used in industries and have been massively introduced in the environment in different chemical forms. Here we report the effect of two different chemical forms of nickel, NiCl2 and nickel nanoparticles (NiNPs), on the reproduction of the marine calanoid copepod Acartia tonsa. The behavior of nickel nanoparticles was analyzed with different techniques and with two pro...

Abstract In this study, nickel nanoparticles (NiNPs) were synthesized and utilized for removing dispersed oil from oilfield-produced water in Sudan. The synthesis process involved using two concentrations of hydrazine as a reducing agent sodium hydroxide solvent. Physiochemical characterizations, such X-ray diffraction (XRD) transmission electron microscopy (TEM), confirmed the successful prepa...

We have considered nanoparticles (NPs) of Fe, Co and Ni, three transition metals sharing similar chemical properties. NP dissolution, conducted by radioactive tracer method and inductively coupled plasma mass spectrometry, indicated that NiNPs and FeNPs released in the medium a much smaller amount of ions than that released by Co NPs. The two considered methodological approaches, however, gave ...

In this work, green and low-cost Ni Nanoparticles/Tissue-derived Nitrogen-doped Porous Carbon Nanocomposites (NiNPs/T-dNPCNs) are prepared through a simple one-step pyrolysis process. The surface morphology composition of the NiNPs/T-dNPCNs characterized by X-Ray Diffraction (XRD), Inductively Coupled Plasma-Optical Emission Spectrometer (ICP-OES), Scanning Electron Microscopy (SEM), Transmissi...

The purpose is to obtain distinguishable optoelectronic and electrical properties. process increases roughness its reactivity, enables tuning optical Based on results from X-ray photoelectron Fourier-transform infrared spectroscopies, magn...

Objective(s): Antibacterial materials are so significant in the textile industry, water disinfection, medicine, and food packaging. Unfortunately, organic compounds for sterilization show toxicity to the human body; therefore, the interest in inorganic disinfectants such as metal oxide nanoparticles (NPs) is increasing. Materials and Methods: Nickel and nickel hydroxide nanoparticles (NiNPs ...

<p>Nickel nanoparticles (NiNPs) have toxic effects on body cells due to the production of free radicals. The purpose this research was investigate protective Gallic acid (GA) and Curcumin (Cur) hepatic transaminases, blood plasma parameters pituitary-testicular hormones levels in NiNPs-treated rats. Seventy adult male Wistar rats were divided 7 groups 10 including control, Ni50 mg/kg, Ni5...

Nickel nanoparticles (NiNPs) have been the subject of extensive research over past decade for a wide range possible applications due to their exceptional strong catalytic activity, high compressive strength, free radical scavenging, and antibacterial property. In consequence this, there has significant advancement in methods producing NiNPs, as well suggested reaction processes these particles....

Nickel nanoparticles (NiNPs) immobilized on halloysite-based supports were straightforwardly synthesized and fully characterized by different techniques with the purpose of evaluating catalytic performance these as-prepared composite materials as catalysts in hydrogenation reactions. Thus, halloysite bearing amino (HAL-NH2) ammonium (HAL-NEt3) groups led to less active comparison unfunctionaliz...
