abstract: this paper is the first study on the impact of ambient temperature on the electrical characteristics and high frequency performances of double gate armchair graphene nanoribbon field effect transistor (gnrfet). the results illustrate that the gnrfet under high temperature (ht-gnrfet) has the highest cut-off frequency, lowest sub-threshold swing, lowest intrinsic delay and power delay ...

Space debris is a serious threat to space travel. Even small fragments are enough damage or destroy satellites. To protect against debris, satellites have protective shields, which come in various forms. These shields must be optimized not only for impact protection but also secondary factors such as weight and size. New shield systems can tested experimentally with high-speed guns. This requir...

High-performance aerospace laminated composite structures manufactured from carbon-fibre prepreg are very susceptible to delamination failure under in-flight impact conditions. Much testing has been conducted at small length scales and quasi-static strain-rates characterise the performance of different material systems loading scenarios. Testing this scale strain-rate is not representative cond...
