transition radiation(tR) induced by electron–matter interaction usually demands vast accelerating voltages, and the radiation angle cannot be controlled. Here we present a mechanism of direction controllable inverse transition radiation(DCItR) in a graphene-dielectric stack excited by low-velocity electrons. the revealed mechanism shows that the induced hyperbolic-like spatial dispersion and the superposition of the individual bulk graphene plasmons(GPs) modes make the fields, which are supposed to be confined on the surface, radiate in the stack along a special radiation angle normal to the Poynting vector. By adjusting the chemical potential of the graphene sheets, the radiation angle can be controlled. And owing to the excitation of bulk GPs, only hundreds of volts for the accelerating voltage are required and the field intensity is dramatically enhanced compared with that of the normal tR. Furthermore, the presented mechanism can also be applied to the hyperbolic stack based on semiconductors in the infrared region as well as noble metals in the visible and ultraviolet ***, the presented mechanism of DCItR is of great significance in particle detection, radiation emission,and so on.

Herein, we report a bottom-up solvothermal route to synthesize a flexible, highly efficient Mos2@sWNt electrocatalyst for hydrogen evolution reactions （HER）. Characterization revealed that branchqike Mos2 nanosheets containing sulfur- rich sites were in situ uniformly dispersed on free-standing single-walled carbon nanotube （sWNt） film, which could expose more unsaturated sulfur atoms, allowing excellent electrical contact with active sites. the flexible catalyst exhibited excellent HER performance with a low overpotential （-150 mV at 10 ma/cm2） and small tafel slope （4l mV/dec）. to further explain the improved performance, the local electronic structure was investigated by X-ray absorption near-edge structure （XANEs） analysis, proving the presence of unsaturated sulfur atoms and strong electronic coupling between Mos2 and sWNt. this study provides an in-situ synthetic route to create new multifunctional flexible hybridized catalysts and useful insights into the relationships electronic structure, and properties among the catalyst microstructure,
