An alternative current (AC) dielectrophoretic lab-on-chip setup was evaluated as a rapid tool of capture and assembly of microalga Chlamydomonas reinhardtii in two-dimensional (2D) close-packed arrays. An electric field of 100 V·cm⁻¹, 100 Hz applied for 30 min was found optimal to collect and assemble the algae into single-layer structures of closely packed cells without inducing cellular oxida...

Study of nanofluids is important for different types of heat transfer management systems. Cupric oxide nanoparticles (CuO NPs) were prepared by the chemical route and different nanofluid samples of CuO NPs dispersed in PVA in different concentrations were prepared using ultrasonication. The apparatus acoustic particle sizer (APS-100) was used to make high precision measurements of the ultrasoni...

copper nanoparticles were fabricated by electro-reduction of cuso4solution in the presence of cetyltrimethylammonium bromide (ctab) cationic surfactant as an additive through potentiostatic method. the prepared copper nanoparticles were characterized by scanning electron microscopy (sem) and electrochemical methods. the sem images reveal that the nanoparticles with diameters at about 70 n...

statement of the problem: during the orthodontic treatment, microbial plaques may accumulate around the brackets and cause caries, especially in high-risk patients. finding ways to eliminate this microbial plaque seems to be essential. purpose: the aim of this study was to compare the antibacterial effects of nano copper oxide (cuo) and nano zinc oxide (zno) coated brackets against streptococcu...

Nanoparticles have long been known and their biomedical potent activities proven that these can provide an alternative to other drugs. In the current study, copper oxide, nickel oxide copper/nickel hybrid NPs were biosynthesized by using Curcuma longa root extracts as a reducing capping agent, followed characterization via UV-spectroscopy, Fourier transformed infrared spectroscopy (FTIR), energ...

Abstract Brassica is one of the crops sensitive to low copper supply, leading Alternaria blight. The present study reflects synthesis myco-derived oxide (M-CuO) nanoparticles (NPs) from Trichoderma asperellum and investigates their effect against blight in two soil types, alluvial calcareous. Foliar applications different treatments were used treat plants: T1 ([email protected]%), T2 (propiconazole@...

The demand for new, thermally conducting light weight and anti-corrosive materials is tried by incorporating Copper Oxide (CuO) nano powder in polyethylene matrix material. A laboratory level electro deposition technique is adopted here to prepare Copper Oxide (CuO) nano particles. Their phase composition is confirmed with X-Ray diffraction peaks and verified with standard JCPDS file for Copper...

Objective(s): This study aimed to determine the possible toxicity of Cuo nanoparticles (NPs) on Oncorhynchus mykiss by evaluating hematological parameters.Materials and Methods: Fish were sampled and treated in 4 aquariums containing the concentration ranges of 1, 5, 20 and 100 ppm of CuO NPs. There was one control group (no CuO NPs) and three replicates. The physicochemical properties of water...

The development of photoelectrochemical (PEC) sensors with novel principles is of significance in realizing sensitive and low-cost detection. This work uses CuO NPs labeled antibody to construct a simple and sensitive sandwich-type immunobiosensor for the detection of protein. The detection signal is produced by dissolving the CuO NPs to release copper ions, which are then added on a quantum do...
