ABSTRACT Insulation failures resulting from partial discharges (PD) in generator stator windings represent a leading cause of generator breakdowns. Conventional acoustic emission sensors for detecting PD ultrasonic signals are typically made from bulky piezoelectric materials and are restricted to external placement on the generator.

Abstract Integrating the attention‐based view with the strategic leadership interfaces perspective, we propose a theoretical model of situational urgency mechanisms influencing the allocation of CEOs' attention towards responsive actions. Specifically, we theorize upon the role of humility, which leads CEOs towards embracing interfaces and makes them ...

Epitaxial piezoelectric α‐quartz/Si BioNEMS sensors, made using soft chemistry, effectively detect the Chikungunya virus. They have a mass sensitivity of 205 pg Hz−1 in liquid and can detect the virus at a limit of 9 ng mL−1. This development enables high‐frequency mass devices for point‐of‐care testing in healthcare and other electronic applications ...

The change in the dielectric function from the heat‐driven amorphous‐to‐crystal Si transformation can be used to engineer large spectral adjustability of Si‐based multilayered narrowband photonic devices operating in the IR region. This effect can be utilized to accurately adjust the resonance wavelength of fabricated amorphous multilayered structures ...
