Abstract: A key challenge in wire-shaped energy storage devices is their complete encapsulation for practical applications.Hence it is of great importance to design and fabricate an all-inclusive structure in which inner and outercurrent collectors, active materials, electrolyte and separator are all enclosed in a single wire structure.However, due to the surface area differences between the shell and core electrodes, the matching of thecapacitance on both electrodes become a challenging task. We solved this problem by using multiple thin Niwires with three-dimensional MnO2-carbon nanotubes (CNTs)-graphene hybrids as the core electrode and a Nitube as the shell electrode in a coaxial-cable supercapacitors structure. Within the seamless tubular electrode,all the necessary components are included and protected by the metal tube shell. The fully encapsulated singlewire devices show a high area-normalized capacitance of 31 mF cm−2 at a current density of 0.29 mA cm−2,comparable to the best cable devices with more exposed structures. Such devices are more suitable forapplications by providing more mechanical stability and avoiding exposure and loss of electrolytes duringoperation.

Abstract: iAl/Ti2AlC composites were successfully synthesized by vacuum arc melting with TiC, graphite powder, and carbon nanotubes (CNTs) as carbon sources. As the amount of Ti2AlC ceramic increased, the microhardness and compressive strength of the TiAl/Ti2AlC composites improved linearly. Importantly, the TiAl/Ti2AlC prepared with TiC as the carbon source exhibited higher microhardness and compressive strength than that composites prepared with graphite powder or CNTs. During vacuum arc melting, three reactions occur successively: Ti+Al→TiAl, Ti+C→TiC, and TiAl+TiC→Ti2AlC. Ti2AlC was formed by peritectic reaction between the TiAl melt and TiC particles. A large amount of TiC was left in the TiAl matrix, which acted to improve the hardness and strength of the composites. The fracture behavior of the composite was mainly transgranular fracture. The pinning, pulling out, and the effect of crack deflecting of TiC particles, together with the interlayer tearing, plastic shearing, folding, and crimping of Ti2AlC played a key role in the improvement of the strength and plasticity of the composites.

Abstract: A simple method for introducing ZrB2 using sol-gel processing into a SiBCN matrix is presented in this paper. Zirconium n-propoxide (ZNP), boric acid and furfuryl alcohol (C5H6O2) (FA) were added as the precursors of zirconia, boron oxide and carbon forming ZrB2 dispersed in a SiBCN matrix. SiBCN/ZrB2 composites with different contents of ZrB2 (5, 10, 15, and 20 wt%) were formed at 2000 °C for 5 min by spark plasma sintering (SPS). The microstructures were carefully studied. TEM analysis showed that the as formed ZrB2 grains were typically 100–500 nm in size and had uniform distribution. HRTEM revealed clean grain boundaries between ZrB2 and SiC, however, a separation of C near the SiC boundary was observed. The flexural strength, fracture toughness, Young's modulus and Vicker's hardness of composites all improved with the ZrB2 contents and SiBCN matrix containing 20 wt% of ZrB2 could reach 351±18 MPa, 4.5±0.2 MPa·m1/2, 172±8 GPa and 7.2±0.2 GPa, respectively. The improvement in fracture toughness can be attributed to the tortuous crack paths due to the presence of reinforcing particles.

Abstract: The microstructural stability of YeTieO nanoparticles during spot laser beam melting of oxidedispersion-strengthened steel powder is investigated. After the spot laser beam melting, Y2Ti2O7 oxidenanoparticles are successfully retained without dissolution or transformation. However, their particlesize is considerably coarser than typical Y2Ti2O7 nanoparticles due to the active agglomeration of the YeTieO nanoparticles, Cr-carbides, and Ar bubbles. In particular, an unexpectedly large volume of Arbubbles embedded or attached to the Y2Ti2O7 nanoparticles is observed. The Ar gas bubbles seem toaccelerate the particle agglomeration. No other phase is observed than Y2Ti2O7 oxide, Cr-carbide and Arbubble in the sample.
