TL;DR: H2S gas sensors fabricated using the α-Fe2O3 nano-ellipsoid-based sensors exhibited high-response values to different concentrations of H2S with a detection limit as low as 100 ppb, as well as excellent repeatability and long-term stability.

TL;DR: An asymmetric supercapacitor was assembled using the CuCo2S4/CNTs-3.2% as the positive electrode and the active carbon as the negative electrode, which exhibited an energy density of 23.2 Wh kg-1 at a power density of 402.7 W kg-1, indicating its excellent cycle stability.

TL;DR: In this article, the zinc cobalt sulfide nanoparticles (ZCS NPs) are firstly synthesized via a hydrothermal method assisted by hexadecyltrimethyl ammonium bromide (CTAB), and then transformed into ZCS nanoparticles using a facile sulfuration process.

TL;DR: In this paper, a self-sacrificial template method was used to synthesize porous Cu(OH)2/Cu7S4 hybrid nanowires for supercapacitors, which had large surface areas and pore volumes, which provided numerous active sites for faradaic reactions and facilitated fast ion diffusion and electron transport.

TL;DR: In this paper, a mesoporous Zr-doped CeO2 nanostructures with large surface area, extraordinarily high porosity and abundant oxygen vacancies were fabricated using a hydrothermal method and an assisted calcination process.
