The integration of solar cells with supercapacitors into hybrid monolithic power packs can provide energy autonomy to smart electronic devices the Internet Things (IoT) by mediating between intermittent load and supply. Herein, such a photorechargeable supercapacitor (also called photosupercapacitor) is developed via three-electrode p–i–n halide perovskite cell gel electrolyte-type that uses me...

For reliability-based topology optimization (RBTO) of double layer grids, a two-stage optimization method is presented by applying “Solid Isotropic Material with Penalization” and “Ant Colony Optimization” (SIMP-ACO method). To achieve this aim, first, the structural stiffness is maximized using SIMP. Then, the characteristics of the obtained topology are used to enhance ACO through six modific...

The NiCo 2 S 4 /C hybrid material was successfully prepared by a simple one-step hydrothermal method. Carbon composite increases the specific surface area of and provides more ion attachment points during electrochemical process. Conducive to transportation transfer, composition carbon greatly improves conductivity material. Electric double-layer capacitor materials can accept transferred ions ...

double layer zno/sno2 thin film resistive gas sensors were fabricated by successive pvd of those oxides onto porcelain substrates. the metallic contacts were provided by electron beam evaporation of platinum onto substrates prior to deposition of the gas sensitive layers. deposits were thermally annealed at different temperatures. it was shown that the activation energy of electrical conduction...
