A ZrC-SiC and TC4 gradient structure (ZTGS) was additively manufactured through the laser deposition technique and brazing process. The research results indicated that SiC-reinforced TC4-based gradient layers could be obtained on the TC4 surface by laser deposition. ZrC-SiC and TC4 coated with gradient layers were brazed using an AgCuTi filler to fabricate the ZTGS. The effects of the gradient structure

Alternating current poling (ACP) in air by changing poling temperature (70 to 130 °C) and voltages (2 to 6 kVrms/cm) on pseudo-ternary 0.24Pb(In1/2Nb1/2)O3-0.46Pb(Mg1/3Nb2/3)O3-0.30PbTiO3 (PIMN-0.30PT) single crystals (SCs) manufactured by continuous-feeding Bridgman (CF BM) method was investigated. Free dielectric permittivity (εT33/ε0) and piezoelectric constant (d33) were improved to be 7000 and

Due to the complex interplay between composition, synthesis parameters and the performance of thermoelectric materials, the optimization of thermoelectric materials needs to be complemented by modelling. A relatively simple and thus popular approach is the so called single parabolic band model, which allows for an efficient optimization of the material properties and a benchmarking of different materials

Lithium metal batteries are regarded as promising alternatives to lithium ion batteries due to their high specific capacity. However, lithium dendrite growth during cycling causes safety problem and rapid capacity loss. Here, we report a composite Li anode composed (LYF) of metallic Li and trace amounts (1–2 wt%) of two-dimensional YFδ. The lithiophilic nature of YFδ enables its homogeneous dispersion
