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...

this study aimed to investigate the effects of tow nanoparticles (nps) on the absorption,accumulation, reproduction of the eisenia fetida. a 4×2×2 factorial experiment in a randomized completeblock design with three replications was conducted. the factors included in the experiment are the content ofnps at four levels (0, 0.4, 0.8, and 1.2gr/kg weight of substrate), the type of nps at two level...

Plasmonics based sensors have been a prominent area of research. Plasmonics based sensors are widely used in bio sensing and many other applications. The basic mechanism in which these sensors operate is that there are metal nano particles that are separated by a very small distance between them. The dimensions of these nano particles is much smaller than the incident light [1]. For sensing pur...

In this paper, chemically synthesized copper oxide nanoparticles (CuO-NPs), were employed for two processes: one is photocatalytic degradation and second one adsorption for the sorption of safranine (SA) dye in an aqueous medium at pH = 12.01. The optimized analytes amount (nano-adsorbent = 0.10 g, conc. range of SA dye 56.13 ppm to 154.37 ppm, pH = 12.01, temperature 303 K) reached to equilibr...

background: nano-particles are extensively employed in most industries. several studies have been started to explore the probable detrimental effects of nano-particles on human reproduction. however, there is insufficient and controversially evident of effects of silver nano-particles on sperm parameters and other reproductive indices. objective: investigation of the effects of silver nano-part...

the potential use of nano technology for improving of withdrawal resistance of nail and screw in wood was evaluated. for this, the maintenance strength of nail and screw was measured under dry and wet conditions for poplar wood (populus nigra) coated with common paints in furniture industry and nano-particles. specimens with dimensions of 15×5×5 cm3 (l×r×t) were cut from poplar wood (populus ni...

In the present research, an efficient process for the synthesis of propargylamine derivatives catalyzed by a novel nanocomposite of CuO/MnO2 is reported. CuO/MnO2 nano-catalyst was synthesized by the co-precipitation process and characterized by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), X-ray diffraction(XRD), ICP-OES and BET surface area an...

Heated scallop-shell (HSS) nano-particles, prepared using a wet grinding mill, and microparticles were examined for their antibacterial activity against vegetative bacterial cells and spores. The median diameters of the nano-particles and micro-particles were approximately 20 nm and 30 µm, respectively. The antibacterial activity of HSS against Escherichia coli increased with an increase in con...

— We report the nanorobotic in situ forming and characterization of memristors based on individual copper oxide nanowires (CuO NWs) and their potential applications as nanosensors with memory (memristic sensors or " memsensors "). A series of in situ techniques for the experimental investigations of memristors are developed including nanorobotic manipulation, electro-beam-based forming, and ele...
