Uniform gold@mesoporous silica nanospheres (Au@MSNs) with a core每shell structure have been successfully fabricated in a facile one-pot method. In the model catalytic reaction of reducing 4-nitrophenol by NaBH4 to give 4-aminophenol, the Au@MSNs exhibit good catalytic activity even after calcination at 950 ∼C.

We demonstrate the first example of a rationally designed triplecantilever based triboelectric nanogenerator (TENG) for harvesting ambient vibration energy. With the assistance of nanowire arrays fabricated onto the surfaces of beryllium每copper alloy foils, the newly designed TENG produces an open-circuit voltage up to 101 V and a short-circuit current of 55.7 米A with a corresponding peak power density of 252.3 mW/m2.

This work presents a comparative research of Mn intercalation into the interfaces of graphene/Rh(111) and h-BN/Rh(111), by using atomically-resolved scanning tunneling microscope (STM) and density functional theory (DFT) calculations. The intercalated islands of h-BN/Mn/Rh(111) usually possess more irregular shapes than that of graphene/Mn/Rh(111), suggesting a stronger interaction of Mn with h-BN/Rh(111) than that of graphene/Rh(111).

We compared the three mainstream carbon nanotubes (arc-discharge, HiPCO, and CoMoCAT) separated using low-cost gel-based column chromatography for thin-film transistor applications and observed a trade-off between transistor mobility and on/off ratio depending on the nanotube diameters.

Information can be written and read at the nanoscale using the desorption of oxygen adatoms from the oxygen-rich MoO2+x/Mo(110) surface by inelastically tunnelling electrons during scanning tunnelling microscopy experiments. The structures of both MoO2(010)/Mo(110) and MoO2+x/Mo(110) are confirmed by density functional theory calculations.
