Highly Nanoporous Nickel Foam as Current Collectors in 3D All-Solid-State Microsupercapacitors.

This study reports a streamlined method for producing a highly nanoporous current collector with a substantial specific surface area, serving as an electrode for microsupercapacitors (MSCs). Initially, commercial Ni foams are patterned into an interdigitated structure by laser cutting. Subsequently, the Ni foams are infused with NiO nanopowders through dip coating, sintering, and reduction in an H atmosphere, followed by the growth of MnO through a redox reaction.

Enhanced Thermoelectric Properties of P-Type Sn-Substituted Higher Manganese Silicides.

This study introduces Sn-substituted higher manganese silicides (MnSi, HMS) synthesized via an arc-melting process followed by spark plasma sintering (SPS). The influences of Sn concentrations on the thermoelectric performance of Mn(SiSn) (x = 0, 0.001, 0.
