Comparative Study between Uses of Intralesional Pulsed Radiofrequency and Radiofrequency Nerve Ablation in Plantar Fasciitis with Calcaneal Spur

The Egyptian Orthopaedic Journal
Background: Heel discomfort accounts for around 10:15% of all foot issues, making it a prevalent issue in society. A calcaneal spur is a protruding anatomical abnormality. The research aims to compare the efficacy of radiofrequency nerve ablation against

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 ...

Conductive Tin Oxide Under the Thermal Budget of Perovskite/TOPCon Tandems: Toward Indium‐Free Contacts

Advanced Materials Technologies, EarlyView.
This work demonstrates that achieving conductive undoped SnOx contacts required careful tailoring of oxygen vacancy (VO) tuning and defect engineering. Controlling oxygen deposition pressure and low‐temperature annealing (300°C) optimizes defect stoichiometry and mitigates carrier scattering. This low thermal budget approach significantly enhances Hall

Coherent Absorption Reveals Colors Hidden in a Grey Fabry–Pérot Cavity

Advanced Optical Materials, EarlyView.
A dielectric thin film shows colors depending on its thickness; this effect can be used to encode information normally accessible through single‐beam spectroscopy. We developed a method to conceal this kind of information, based on coating the dielectric with a matched conductor, that suppresses the color‐bearing thin‐film resonances.
