Summary of "Uniform generation of NiCoS with 3D honeycomb-like network structure on carbon cloth as advanced electrode materials for flexible supercapacitors."

Direct generation of active materials on carbon cloth (CC) is regarded as an efficient and convenient means to obtain flexible electrodes with high supercapacitor performance. However, uniform generation of active materials on the both sides of CC remains a great challenge. Herein, a facile hanging-hydrothermal method was used to directly generate uniform NiCoS nanosheet arrays on carbon cloth (NiCoS/CC), which was then utilized as the positive electrode for flexible supercapacitors. Taking advantage of the unique and uniform honeycomb-like structure of NiCoS nanosheets, the obtained NiCoS/CC electrode can deliver an excellent specific capacitance (1638 F g at 1 A g), which is significantly higher than NiCoO/CC electrode (657.4 F g at 1 A g). A two-electrode flexible supercapacitor was assembled using NiCoS/CC as positive electrode and carbon cloth coated with activated carbon as negative electrode and revealed a high energy density of 25.2 Wh kg at a power density of 799.6 W kg, highlighting its great potential for flexible supercapacitor applications.

Medical and Biotech [MESH] Definitions

Adjustment of BRAIN WAVES from two or more neuronal groups within or across a brain structure (e.g., cortical and limbic brain structures) to become uniform in EEG oscillation patterns in response to a stimulus. It is interpreted as a brain integration sign during many processes such as learning, memory, and perception and involves reciprocal neural connections.

A perilipin that localizes to LIPID DROPLETS; CYTOPLASM; ENDOSOMES; and PLASMA MEMBRANE, especially in MACROPHAGES. It functions as a transporter of free fatty acids to lipid droplets to promote their biogenesis and growth. It is also required for the transport of the MANNOSE-6-PHOSPHATE RECEPTOR from endosomes to the TRANS-GOLGI NETWORK. Its structure consists of four helix bundles that interact with the hydrophobic lipid droplet surface.

A microscopic imaging technique that takes advantage of the process of harmonic generation that occurs when photons interact to generate new photons of a different wavelength. In second harmonic generation, two photons of the same wavelength and frequency, such as from a LASER, interact inside a medium and are converted to a photon of twice the frequency and half of the wavelength of the two incident photons. The light signals captured are used to produce images that are dependent on the unique optical properties of the material.
