in this research the influence of adding sic on microstructure and electrical properties of zno-based nanocomposite varistors were investigated. sic was added with amounts of 10-0 mass% to zno-based varistor composition. it is found that sic allows reaching to high threshold voltage with formation of fine-grained zno.another important effect of adding sic is formation zn2sio4 (willemite) on the ...
In this research zinc oxide (ZnO) nano-crystalline powders were prepared by sol-gel method using zinc acetate. The ZnO nanoparticles were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), ultraviolet-visible (UV-Vis), Fourier transform infra-red (FT-IR) and energy dispersive X-ray (EDX) spectroscopy. The structure of nanoparticles was studied using XRD pattern. The c...
Abstract. Sandanayake CLT, Weerakoon SR, Karthikeyan N, Somaratne S. 2022. Yield performances of rice varieties (Oryza sativa) under nano-CuO and nano-ZnO micronutrient fertilizers. Nusantara Bioscience 14: 95-103. Rice sativa L.) is a major staple food in the world. There an extreme need for higher yield to meet ever-increasing demand with rise population despite hampering impact climatic chan...
The accumulation of marine biological growth has irreversible negative effects on shipping and coastal fisheries. In this paper, a new antibacterial nanofiller—triazole fluoroaromatic hydrocarbon?modified nano?zinc oxide (ZnO?APTES?TRF)—was prepared by Cu(I)?catalyzed azide–alkyne click chemical reaction. modification nano?ZnO with triazole ring hydrocarbons were testified FT?IR, XPS, EDS. graf...
This research was conducted to investigate the effect of zinc oxide Nanoparticles (nano-ZnO) in diets on the performance, antioxidant status, enzymes activity and some hematological parameters of broiler chickens. A total of 600 one–day-old male Ross 308 broilers were allocated to four treatment groups with five replications of 30 each from day 1 to 42 day of age. The birds were continuously di...
Abstract We report a “nano-on-micro” approach for growth of cactus-like nanostructures zinc oxide (ZnO) gas sensing application. use electrospun polymeric fibers doped with catalyst nanoparticles as the template and employ vapor-liquid-solid (VLS) method to ZnO nanostructures. Controlling processing variables in VLS process yields needle-like around fibers, which resembles needles cactus. The n...
Nano-metallic oxide particles have been found to be potentially effective microstructural reinforcements for cement mortar and become a research hotspot in recent years nano-modification technology of building materials. However, different conclusions obtained due various researchers used methods, which resulted deficiency the performance comparison between nano-metallic particles. In present s...
We describe the diagnostics of the particle dynamics during nanoparticle formation by pulsed laser ablation in a background gas. First, we describe the deposition of ZnO nano-structured thin films, along with the results of Rayleigh scattering observation of ZnO nanoparticle formation in the ablation plume. Then, we propose a new imaging technique, called re-decomposition laser-induced fluoresc...
Effect of different spiking procedures on the distribution and toxicity of ZnO nanoparticles in soil
Due to the difficulty in dispersing some engineered nanomaterials in exposure media, realizing homogeneous distributions of nanoparticles (NP) in soil may pose major challenges. The present study investigated the distribution of zinc oxide (ZnO) NP (30 nm) and non-nano ZnO (200 nm) in natural soil using two different spiking procedures, i.e. as dry powder and as suspension in soil extract. Both...
