Bulk tantalum mononitrides were prepared at high pressure and temperature,The bulk samples was synthesized by direct conversion sintering in different pressure and temperature condition.
Superhard materials with rigid bonding networks have been the focus of intense research over the past decades,which are of great importance in science and applications[1].
NiO was treated as a typical example of a "Mott" insulator with a wide d-d energy gap U.And Mott predicted possible insulator-metal transition in compressed NiO.
Laser-driven flyers has unique advantages of high flyer velocity,low cost,simple facility compared with the flyers driven by other conventional dynamic high-pressure loading techniques.With the fast d
Shock-induced deformation of columnar nanocrystalline Al is investigated by implementing large-scale molecular dynamics simulations,and atomic scale orientation mapping for microstructural analysis.
Under high pressure,unsaturated bond systems generally undergo irreversible transfonnations to produce carbon-based polymeric materials with peculiar properties.
Light elements(e.g.,Li,B,C)with extraordinary bonding features often present novel physical properties,such as superconductivity,metal-insulator transitions,and superhardness.
