We have developed a general route for combining Ni, Fe, Co, Cu, and Pd in nanoparticle using the exsolution mechanism from LaFe0.7Ni0.1Co0.1Cu0.05Pd0.05O3 perovskite oxide precursors. The strong adherence of nanoparticles to support yields attractive catalytic properties dry methane reforming, such as coke resistance thermal sintering suppression. reduction precursors at 700 900 °C yielded NiCo...

Ta/Ru/Co/Ru/Co/Cu/Co/Ni80Fe20/Ta spin-valve giant magnetoresistive (GMR) multilayers were deposited using UHV magnetron sputtering and optimized to achieve a 13% GMR ratio before patterning. The GMR multilayer was patterned into 12 sensor arrays using a combination of e-beam and optical lithographies. Arrays were constructed with 400 nm × 400 nm and 400 nm × 200 nm sensors for the detection of ...

Research has demonstrated that metallic nanoparticles produce toxicity in aquatic organisms that is due largely to effects of particulates as opposed to release of dissolved ions. The present research examined the interplay of nanoparticle composition and dissolution on response of the zebrafish gill following exposure to toxic (nanocopper or nanosilver) or nontoxic (nano-TiO2) nanometals. Fema...

The objective of this study is to develop a mathematical model for chemically reacting magnetic nanofluid flow with thermophoretic diffusion, Brownian motion and Ohmic heating in Darcian permeable regime. current also considers number different types i.e. Cu, Ag Au nanoparticles base fluid ethylene glycol. Effectively nanoscale formulation combining the Buongiorno two-component Tiwari-Das deplo...

Nanoparticle synthesis using plant extracts is biologically safe, cost-effective, and environment-friendly, hence attracting many researchers owing to its advantages over chemical or physical methods. In the current study copper silver nanoparticles have been synthesized by biological methods (using fruit extract). The leftover fruits collected from vendors were used for study, such as guava (P...

Laminar and turbulent mixed convection heat transfer of water/Cu nanofluids in a rectangular shallow cavity was studied utilizing a two-phase mixture model. The upper movable lid of the cavity was at a lower temperature compared to the bottom wall. Simulations were performed for Grashof numbers of 105 (laminar flow) and 1010 (turbulent flow) for Richardson numbers from 0.03 to 30, and nanoparti...

Ciprofloxacin (1-cyclopropyl-6-fluoro-1, 4-dihydro-4-oxo-7-(1- piperazinyl) - 3-quinoline carboxylic acid, cpfH) is a member of synthetic antibacterial agent widely used in clinical practice for the treatment of various gram negative and positive microorganisms. In concurrent use of ciprofloxacin with cations, they may bind together and result to formation complex by chelating. Formation of che...

The pesticide residues with low concentration are important to detect in food safety. Although a lot of methods, such as spectrophotometry, colorimetry and liquid chromatography, used residues, they often suffer from efficiency long detection time. Here, hybrid Surface Enhanced Raman Scattering (SERS) substrate, namely, Au nanoparticle/copper-based graphene/arrayed cone cavities ([email protect...

A steady incompressible boundary layer flow and heat transfer past on a moving thin needle saturated with hybrid nanofluid are investigated the effects of solar radiation viscous dissipation. The simulation is also influenced by thermophoresis Brownian motion. We consider (Al2O3-Cu-water) as nanofluid, where water base fluid alumina copper nanoparticles. By utilizing technique similarity transf...

The mathematical modeling of unsteady flow micropolar Cu–Al2O3/water nanofluid driven by a deformable sheet in stagnation region with thermal radiation effect has been explored numerically. To achieve the system nonlinear ordinary differential equations (ODEs), we have employed some appropriate transformations and solved it numerically using MATLAB software (built-in solver called bvp4c).
