Tunneling field-effect transistors (TunnelFET), a leading steep-slope transistor candidate, is still plagued by defect response, and there is a large discrepancy between measured and simulated device performance. In this work, highly scaled InAs/InxGa1−xAsySb1‑y/GaSb vertical nanowire TunnelFET with ability to operate well below 60 mV/decade at technically relevant currents are fabricated and char

Explorations and analysis of soundscapes have, since Canadian R. Murray Schafer's work during the early 1970's, developed into various established research - and artistic disciplines. The interest in sonic environments is today present within a broad range of contemporary art projects and in architectural design. Aesthetics, psychoacoustics, perception, and cognition are all present in this expand

Certain types of implanted medical devices depend on oxygen supplied from surrounding tissues for their function. However, there is a concern that the tissue associated with the foreign body response to implants may become impermeable to oxygen over the long term and render the implant nonfunctional. We report oxygen flux recordings from electrochemical oxygen sensor devices with wireless telemetr

An implantable sensor capable of long-term monitoring of tissue glucose concentrations by wireless telemetry has been developed for eventual application in people with diabetes. The sensor telemetry system functioned continuously while implanted in subcutaneous tissues of two pigs for a total of 222 and 520 days, respectively, with each animal in both nondiabetic and diabetic states. The sensor de

The ability to rapidly detect cell free circulating (cfc) DNA and other nanoparticulate disease biomarkers directly in blood is a major challenge for nanomedicine. We now show that AC Electrokinetic (ACE) microelectrode array devices can be used to rapidly isolate and detect cfc-DNA nanoparticulates directly from whole blood and other high conductance samples (plasma, serum etc.). The device shows

In this paper, we present and discuss the methodology to monitor average residual stresses in aged high temperature unidirectional and woven graphite fiber/PMR-15 composites. The aging experiments were performed at 315 °C for 1170 h in nitrogen and 1064 h in air, respectively. The proposed methodology was based on X-ray diffraction (XRD) strain measurements in embedded crystalline metallic inclusi

An overview is given of the most important characteristics of the brittle fracture process. In addition, several experimental techniques are suggested for the simulation of brittle fracture under laboratory conditions.

A review of several typical enhanced heat transfer tubes such as corrugated tube, transversally corrugated tube, twisted tube and spiral fluted tube, is carried out. Compared with smooth wall tube, these enhanced tubes have higher heat exchange capacity and better anti - fouling ability. Besides, the heat transfer efficiency can be promoted to a higher level if the objects that can disturb flow ar
