A hybrid energy storage system (HESS), that comprises of a battery and a supercapacitor, is utilized to absorb the power and energy oscillations for a wave energy conversion system so as to inject a ...

High-pressure air injection (HPAI) in light oil reservoirs has proven to be a valuable improved oil recovery (IOR) process and aroused more attention worldwide. In this research, laboratory ...

This paper presents an impact-induced frequency up-conversion piezoelectric energy harvester (FUC-PEH) to improve low-frequency output performance. The FUC-PEH includes a high-frequency piezoelectric ...

Heat transfer is the physical act of thermal energy being exchanged between two systems by dissipating heat. Temperature and the flow of heat are the basic principles of heat transfer.

Risen Energy’s mass-produced heterojunction modules have reached a cell conversion efficiency of 26.61%, a record figure for ...

Kinetic and nonkinetic contributions to the Tafel slope value can be separated using a Tafel slope plot, where a constant Tafel slope region indicates kinetic meaningfulness. Here, we compare the ...
