Hierarchical Co(OH)@NiMoS nanocomposite on carbon cloth as electrode for high-performance asymmetric supercapacitors.

Hierarchical Co(OH)@NiMoS nanocomposites were successfully prepared on a carbon cloth by using a simple two-step hydrothermal method coupled with a room-temperature vulcanization method. The resulting nanocomposites were composed of large-scale uniform Co(OH) nanowires fully covered with ultrathin vertical NiMoS nanoflakes. Because of the synergetic effect between Co(OH) and NiMoS, the nanocomposites exhibited good electrochemical performance as a supercapacitor electrode.

Synthesis of an ordered nanoporous Cu/Ni/Au film for sensitive non-enzymatic glucose sensing.

Ordered nanoporous Cu/Ni/Au film was prepared by electrochemical deposition and magnetron sputtering using an anodic aluminium oxide template. The fabricated porous film has a uniform hexagonal pore size structure, a long-range ordered arrangement, and a pore diameter of approximately 40 nm. Following the dissolution of the template, the independent Cu/Ni/Au film is devolved to an ITO substrate as an effective non-enzyme glucose detection sensor.

The fabrication of an NiMnO nanoflake-modified acupuncture needle electrode for highly sensitive ascorbic acid detection.

The current work describes the use of a steel acupuncture needle as an electrode substrate in order to construct an NiMnO nanoflake layer-modified microneedle sensor for highly sensitive ascorbic acid detection. For the purpose of constructing the functionalized acupuncture needle, first, a carbon film was layered on the needle surface as the seed layer. Subsequently, a straightforward hydrothermal reaction-calcination process was employed for the growth of NiMnO nanoflakes on the needle to function as a sensing interface.
