Nanoscientists at Northwestern University have developed a blueprint to fabricate new heterostructures from different types of 2-D materials. The researchers describe their blueprint in the Journal of Applied Physics. In this image: Top: Vertical MoSe2-WSe2 heterostructure, radial MoS2-WS2 heterostructure, hybrid MoS2-WS2 heterostructure and Mose2-WSe2 alloy building block representations and crystal structure models Bottom: Vertical MoSe2-WSe2 heterostructure crystal structure model
The combustion boiler in the Chalmers Power Central was converted to a gasifier in 2007. Since then, more than 200 man-years of research have been devoted to gasification technology. The power central produces district heating and cooling that covers Chalmers University of Technologys' entire needs. The first boilers in the power central were built in 1947.
Non-local transport measurements reveal a novel voltage peak at superconducting transition temperature in gold nanowire with superconducting W electrodes. The voltage peak appears when cooling the sample across Tc, while the peak turns into dip in the warming process. Upper inset, a scanning electron microscope image of Au nanowire contacted by two superconducting W compound electrodes in the middle and two normal Pt electrodes at the ends. Lower inset, configuration of electrodes. In fact, the detected peak is irrelevant to the current, and similar phenomena can be observed even in the absence of current.
