n‐Type Polymer Radio Frequency Rectifiers Operating at 18.5 GHz

Advanced Materials, EarlyView.
Combining an n‐doped polymer semiconductor with wafer‐scale asymmetric planar electrodes featuring work function‐engineered contacts yields radio‐frequency diodes and rectifying circuits operating at up to 18.5 GHz. The devices combine scalable manufacturing with an operating frequency previously unattainable by large‐area organic electronics ...

Design and Line Fault Protection Scheme of a DC Microgrid Based on Battery Energy Storage System

Energies, 2018
Currently, the Direct-Current (DC) microgrid has been gaining popularity because most electronics devices require a DC power input. A DC microgrid can significantly reduce the AC to DC energy conversion loss.

Optimal Power Flow in Stand-alone DC Microgrids [PDF]

, 2017
Direct-current microgrids (DC-MGs) can operate in either grid-connected or stand-alone mode. In particular, stand-alone DC-MG has many distinct applications. However, the optimal power flow problem of a stand-alone DC-MG is inherently non-convex. In this

Optimal Power Flow for Unbalanced Bipolar DC Distribution Grids

IEEE Access, 2018
The emergence of distributed energy resources can lead to congestion in distribution grids. DC distribution grids are becoming more relevant as more sources and loads connected to the low voltage grid use dc. Bipolar dc distribution grids with asymmetric loading can experience partial congestion resulting in a nodal price difference between the two ...

An Active Balancer of Currents for Bipolar DC Power Grids

2025 IEEE Seventh International Conference on DC Microgrids (ICDCM)
DC power grids (DCPGs) are gaining more significance, predominantly due to the natural DC operation of technologies such as renewables, energy storage systems, and electric vehicles. Particularly, thanks to power electronics, bipolar DCPGs are gaining more preponderance since they enable reducing power losses, increasing power density, and averting ...

Advanced Separators for Liquid and Quasi‐Solid Lithium Rechargeable Batteries: Design and Development

Advanced Materials, EarlyView.
This review traces the evolution of lithium‐ion battery separators from passive barriers to multifunctional components central to cell safety and performance. Polymer‐ceramic hybrids, nanofiber architectures, and bio‐derived membranes deliver ionic conductivities above 3 mS cm−1, thermal stability beyond 200 °C, and effective suppression of lithium ...
