The study shows how Saharan silver ants utilize a uniquely shaped hair coating to substantially enhance reflectivity in the solar spectrum and emissivity in the mid-infrared. Biomimetic metasurfaces with such radiative-cooling properties are also reported.
Beryllium, due to its excellent neutron multiplication and moderation properties, in conjunction with its good thermal properties, is under consideration for use as plasma facing material in fusion reactors and as a very effective neutron reflector in fission reactors. While it is characterized by unique combination of structural, chemical, atomic number, and neutron absorption cross section it suffers,...
We report fabrication of single-walled carbon nanotube field-effect transistors and inverters using semiconductors as the source/drain contact material. The electrical properties were measured from the fabricated devices. The fabricated carbon nanotube field-effect transistor has high on/off drain-source current ratios and excellent saturation of drain-source current, and the inverter has excellent...
