Near-thermal limit gating in heavily-doped III-V semiconductor nanowires using polymer electrolytes

open access: yes, 2018
Doping is a common route to reducing nanowire transistor on-resistance but has limits. High doping level gives significant loss in gate performance and ultimately complete gate failure.

Bifenthrin Baseline Susceptibility and Evaluation of Simulated Aerial Applications in \u3ci\u3eStriacosta albicosta\u3c/i\u3e (Lepidoptera: Noctuidae) [PDF]

open access: yes, 2019
Striacosta albicosta (Smith) is a maize pest that has recently expanded its geographical range into the eastern United States and southeastern Canada. Aerial application of pyrethroids, such as bifenthrin, has been a major practice adopted to manage this

Experimental Study of Ultra Shallow Floor Beams (USFB) with Perforated Steel Sections [PDF]

open access: yes, 2009
: In modern building construction design, floor spans are becoming longer. Hence, steel framed structures have become more competitive when compared with traditional reinforced concrete framed buildings. In order to minimise the structural section of the

Experimental Validation of External Load Effects for Micro-Contacts under Low Frequency, Low Amplitude Alternating Current (AC) Test Conditions [PDF]

open access: yes, 2018
The use of micro-contacts has been demonstrated in various radio frequency (RF) applications. However, the premature failure of such devices under alternating current (AC) operations is still a hurdle to further development.

The Research on Hidden Failures of Civil Aircraft

open access: yesMATEC Web of Conferences, 2016
The hidden failure is often appear on civil aircraft, and it is a big risk for normal safe operation. The reason for this failure is the instability of the resistance of the electrical contact.
