The ferromagnetic shape memory alloy Ni 2 MnGa has been successfully grown on GaAs by molecular beam epitaxy. In-situ reflection high energy electron diffraction, ex-situ X-ray diffraction and transmission electron microscopy selective area electron diffraction indicate the single crystal growth of a pseudomorphic tetragonal phase of Ni 2 MnGa on (001)(More)
The Square Kilometre Array (SKA) project is an international effort to build the world's largest radio telescope, with a one-square-kilometre collecting area. In addition to its ambitious scientific objectives, such as probing cosmic dawn and the cradle of life, the SKA demands several revolutionary technological breakthroughs, such as ultra-high precision(More)
BACKGROUND AND PURPOSE N(6)-(3-methoxyl-4-hydroxybenzyl) adenine riboside (B2) is an analog of N(6)-(4-hydroxybenzyl) adenine riboside (NHBA), which was originally isolated from Gastrodia elata Blume. Our laboratory has previously demonstrated that B2 can produce strong sedative and hypnotic effects, but the mechanism remains to be determined. There is(More)
