Organic Electrochemical Transistors and Foreign Body Reaction: First Steps Toward Long‐Term Implantable Biosensing

Advanced Electronic Materials, EarlyView.
Organic Electrochemical Transistors (OECT) have been applied as implanted sensors in recent years. However, Foreign Body Reaction (FBR) effects on OECT performance are still underexplored. Here, we analyze OECT operation when covered by FBR‐related proteins in an in vitro scenario.

GaN‐Based Three‐Phase Voltage and Current Sources for Power Relay Testing

IET Power Electronics
This paper implements low‐cost GaN‐based three‐phase voltage and current sources to validate power protecting relays. This proposal develops a voltage generator that uses three single‐phase full‐bridge converters equipped with an LC filter and an ...

Reduced Variability in Threshold Switches Using Heterostructures of SiOx and Vertically Aligned MoS2

Advanced Electronic Materials, EarlyView.
Heterostructures of SiOx and vertically aligned MoS2 exhibit reliable threshold switching by guiding Ag ion migration through van der Waals gaps. Compared to SiOx‐only devices, these heterostructures demonstrate higher switching voltages, faster switching speeds, and reduced variability.

Pressure‐Induced Structural and Magnetic Evolution in Layered Antiferromagnet YbMn2Sb2

Advanced Electronic Materials, EarlyView.
Pressure tunes the delicate balance between structure, magnetism, and electronic states in quantum materials. In YbMn2Sb2, high‐pressure X‐ray and neutron diffraction reveal a trigonal‐to‐monoclinic transition near 3.5 GPa, accompanied by unconventional magnetic ordering.

Optimization of battery/ultra‐capacitor hybrid energy storage system for frequency response support in low‐inertia microgrid

IET Power Electronics
Modern power system networks are under statutory obligations to integrate renewable energy sources (RES). The primary reason is to meet ever‐increasing energy demand and also to curtail environmental pollution by greenhouse gases.

Enhanced Fast‐Charging Performance of High‐Mass‐Loading Mn‐Rich Li[Mn1‐xFex]PO4 Cathodes via LiF‐Less Cathode–Electrolyte Interphase

Advanced Energy Materials, EarlyView.
LiF‐rich@LMFP develops a CEI enriched with electronically and ionically insulating LiF that impedes interfacial charge transfer during fast charging. By suppressing interfacial LiF formation, LiF‐less@LMFP accelerates Li+ exchange and lowers overpotentials, delivering 1.6‐fold higher capacity at 5C and ∼87% retention after 100 cycles under practical ...

Selective Charge Extraction Allows Fast Photomultiplication and Imaging in Rigid and Ultra‐Flexible SWIR Organic Photodiodes

Advanced Energy Materials, EarlyView.
SWIR donor polymer TQ‐3T allows photomultiplication in OPD in 1:1 ratio with NFA Y6, achieving EQEs > 1100% at ‐10 V. Microseconds response times are retained, amongst the lowest for photomultiplication. As proof of concept, we demonstrate ultrathin and flexible PM‐OPDs based on our TQ‐3T:Y6 as a flexible pulse oximeter as well as a conformable image ...
