Atmospheric-pressure microplasma-assisted electrochemistry was used to synthesize Ag nanoparticles (NPs) for plasmonic applications. It is shown that the size and dispersion of can be controlled by variation electrochemical process parameters such as electrolyte concentration temperature. Moreover, NP synthesis also achieved in absence a stabilizer, with additional control over formation possible. As microplasma directly reduces ions solution, incorporation toxic reducing agents into...
Abstract Si 3 N 4 ceramic was densified at 1900°C for 12 hours under 1 MPa nitrogen pressure, using MgO and self‐synthesized Y 2 6 C as sintering aids. The microstructures thermal conductivity of as‐sintered bulk were systematically investigated, in comparison to the counterpart doped with O ‐MgO additives. addition induced a higher nitrogen/oxygen atomic ratio secondary phase by introducing promoting elimination SiO , resulting enlarged grains, reduced lattice oxygen content, increased ‐Si...
The application of an electric field over a ceramic powder compact at elevated temperatures gives rise to "flash sintering". phenomenon occurs critical combination and temperature, which leads rapid increase in the power dissipated within sample. This results sample densification far shorter timescales than those required with conventional sintering. paper reports first successful pressureless flash sintering SiC B C aids. Mean relative densities up 94.4% have been achieved several minutes...
An ultra-wideband absorber with an absorption rate of near unit is studied and numerically simulated in the terahertz frequency band. The proposed a stacked compact structure consisting double-layer patterned graphene embedded between two separated dielectric. Under normal incidence, exceeds 99% at 2.31–3.92 THz. bandwidth can reach 2.54 THz for absorptions greater than 90% (1.91–4.45 THz), relative achieves 80%. Furthermore, tunable, ranging from 14% to almost 99.9% by altering Fermi energy...
Abstract SiC ceramics were fabricated by spark plasma sintering of β‐SiC powder with various rare‐earth (RE = La, Gd, Yb, Sc) oxides and magnesia additives. The phase compositions, microstructures, lattice oxygen contents, thermal conductivities systematically investigated. A decrease in the cationic radius element resulted an increased field strength. This enhanced attraction to anion led higher viscosity improved high‐temperature stability intergranular RE‐Mg‐Si‐O liquid phase. After at...
S‐SiC ceramics with >96% of densification degree were derived from 0.8‐ to 8.6‐μm graded powders for the first time after sintered at 2210°C. Grain grading generated a 21.8% increase in green density and 40.8% decrease sintering shrinkage (low 12.2%). The introduction micrometer‐sized coarse particles suppressed abnormal grain growth owing their pinning effect, thus resulting equiaxial grains. Dramatically improved fracture toughness peaked 3.77 MPa·m 1/2 50 wt% added powder. Sintering...
The microstructure, thermal conductivity, and electrical properties of pressureless densified SiC– BN composites prepared from in situ reaction Si 3 N 4 , B C, C were systematically investigated, to achieve outstanding performance as substrate materials electronic devices. increasing content (0.25–8 wt%) the resulted finer higher resistivity, lower dielectric constant loss, at expense only slight degradation conductivity. subsequently annealed showed more homogeneous microstructures with...
