Nowadays bimetallic nanoparticles (NPs) have emerged as key materials for important modern applications in nanoplasmonics, catalysis, biodiagnostics, and nanomagnetics. Consequently the control of bimetallic structural motifs with specific shapes provides increasing functionality and selectivity for related applications. However, producing bimetallic NPs with well controlled structural motifs s...

We investigate the dynamical superlattice correlation in the two-dimensional three-band Hubbard model on the basis of the unrestricted fluctuation exchange approximation. We calculate the one-particle spectral function, the spin correlation function and the charge correlation function at finite temperature. We find that some experimental results can be reproduced consistenly by taking inhomogen...

Dispersions of nanoscale Pb particles embedded in Si, Al, and Cu matrices have been synthesized by ion implantation and subsequent annealing. The melting transitions of the embedded Pb nanocrystals with epitaxial particle/matrix interfaces were investigated by means of in situ high-temperature X-ray diffraction. Due to different levels of lattice mismatch, the Pb nanoprecipitates experience a d...

Copper-based nanoparticles (Cu NPs) were prepared using methanol plant extract of Polyalthia longifolia roots (PLR) for the first time. The is potential to be as reducing and stabilising agent formation Cu-based nanoparticles. results reduction reaction Cu(II) ions by PLR Cu, CuO2, Cu2O CuO NPs confirmed X-Ray Diffraction (XRD). UV-Vis Spectrophotometer revealed surface plasmon resonance (SPR) ...

In situ measurements of plasma properties during gas-condensation of Cu nanoparticles" (2016). Since the mean, standard deviation, and modality of nanoparticle size distributions can vary greatly between similar input conditions (e.g., power and gas flow rate), plasma diagnostics were carried out in situ using a double-sided, planar Langmuir probe to determine the effect the plasma has on the h...

On Cu/ZrO2 catalysts, variation of the Cu loading from 0.2 wt% to 80 allows assessing influence Cu-ZrO2 interface on methanol steam reforming (MSR) performance by steering particle size and morphology, revealing contribution potential active sites at intrinsic relative contributions support surface fraction. As ZrO2 influences both CO2-selective selectivity-spoiling MSR reaction channels, disen...

The effects of lanthanum hexaboride (LaB6) nano-particles on the electrical, thermal, and mechanical properties copper-based nanocomposites (Cu-LaB6) produced using microwave sintering (MS) spark plasma (SPS) processes were investigated in this study. Nano LaB6 particles reduced electrical conductivity Cu matrix via MS SPS by 20% 13%, respectively. Cu-LaB6 had lower thermal than unreinforced Cu...

The metallurgy, mechanical properties, and corrosion of Cu, proposed as the barrier for Canadian used fuel containers (UFCs) use in a deep geological repository (DGR), have been studied decades. Bulk properties reported, knowledge applied to strengthen performance Cu produced by electrodeposition cold spray. Despite this success, many degradation mechanisms are unclear from bulk testing, which ...
