Passive Arc Suppression Based on Reverse Potential Compensation for Grounding Faults

IEEE Access
Arc suppression is a common solution to single-phase grounding faults. Nevertheless, arc suppression methods based on current compensation suffer from fundamental residual currents (passive), complicated control process and strict implementation ...

Novel Series Arc Fault Detector Using High-Frequency Coupling Analysis and Multi-Indicator Algorithm

IEEE Access, 2019
In the field of arc fault detection, it is universally acknowledged that it is very hard to judge whether there is an arc fault through signals of the main line when a masking load (such as air compressors, lamps with dimmers, and so on) is in parallel ...

Modeling of Secondary Arc on High Voltage Solar Array in Space

, 2006
Secondary arc on solar array in space is defined as an arc discharge short-circuiting adjacent solar cells. As operational voltage of spacecraft increases to 100V, there is more risk of secondary arc that can destroy solar array circuit. Secondary arc is

Toward Pore‐Engineered 3D‐Printed Materials for Sorption Water Harvesting, Interfacial Evaporation, and Radiative Cooling

Advanced Materials, EarlyView.
Water harvesting, radiative cooling, and interfacial solar evaporation are fundamentally governed by coupled heat, mass, and light transport processes. These processes are mediated by pore architecture, including pore size, connectivity, and hierarchical organization.

Regulating Phase Evolution and Crystallization Dynamics Enables Low Open‐Circuit Voltage Deficit in Wide‐Bandgap Cu2ZnSnS4 Solar Cells

Advanced Materials, EarlyView.
Bilayer composition‐modulated sulfurization (BCMS) regulates Cu redistribution in solution‐processed Cu2ZnSnS4, suppressing Cu2SnS3 and favoring the direct transformation pathway, while transforming the crystallization from surface‐dominated growth to a more synchronized process.

Fabrication of Aligned Polycaprolactone Nanofibrillar Bundles to Control Cell‐Mediated Collagen Deposition in Engineered Cartilage

Advanced Materials, EarlyView.
Melt electrofibrillation (MEF) enables the fabrication of nanofibrillar PCL scaffolds with defined architectures that guide cellular alignment and retention during cartilage tissue engineering. Unlike conventional melt electrowriting, MEF consistently directs collagen type II‐rich extracellular matrix organization, providing a tunable platform to ...
