A novel 2.45 GHz self-adaptive rectifier with high efficiency and a wide input power range is proposed in this paper. It consists of high-power sub-rectifier branch, low-power an impedance transform isolation network (ITIN), feedback network. Impedance matching realized by ITIN for both branches. The design able to switch between these two branches the according its output voltage level. has be...

In this current research, we described an enhanced power conversion efficiency of dye sensitized solar cell (DSSC) and fabricated through Few Layered Graphene (FLG)/CuO nanocomposite synthesized by ultrasonic assisted synthesis (UAS) by varying of FLG (1, 2 and 3 wt%) ratio. The FLG/CuOnanocomposites characteristic features understood through various microscopic techniques such as FE-SEM and HR...

New design and optimization of charge pump rectifiers using diode-connected MOS transistors is presented in this paper. An analysis of the output voltage and Power Conversion Efficiency (PCE) is given to guide and evaluate the new design. A novel diode-connected MOS transistor for UHF rectifiers is presented and optimized, and a high efficiency N-stage charge pump rectifier based on this new di...

A 4-chlorobenzene sulfonyl chloride (CBSC) passivated perovskite solar cell device shows a high-power conversion efficiency (PCE) of 20.02% with improved long-term stability.

A network may comprise multiple layers. It is important to globally optimize network resource utilization, taking into account all layers rather than optimizing resource utilization at each layer independently. This allows better network efficiency to be achieved through a process that we call inter-layer traffic engineering. The Path Computation Element (PCE) can be a powerful tool to achieve ...

BACKGROUND Trichloroethene and tetrachloroethene are the most common pollutants in groundwater and two of the priority pollutants listed by the U.S. Environmental Protection Agency. In previous studies on TCE and PCE photolysis and photochemical degradation, concentration ranges exceeding environmental levels by far with millimolar concentrations of TCE and PCE have been used, and it is not cle...
