A two-dimensional lateral transition metal disulfide-oxide-disulfide heterostructure with a configuration of an ultrathin Nb2O5 channel and two metallic NbS2 electrodes is fabricated by a simple lithographyfree, laser-patterning technique. The heterostructure can be used as an ultrasensitive two-terminal sensor based on the modulation of Nb2O5 surface conduction through the naturally adsorbed water molecules.

The atomically thin Ni-Se-S based hybrid nanosheet (NiSe1.2S0.8) has been synthesized via a simple solvothermal method, and the thickness of NiSe1.2S0.8 nanosheets is only about 1.1 nm. Benefiting from the ultrathin nanostructure and rich defects, the optimal NiSe1.2S0.8 exhibits good electrocatalytic activity in acid solution.

In this letter, we used scanning photoluminescence and Raman spectroscopies to quantify the local strain over few-layer MoS2 (3–5 ML) bubbles and demonstrated a continuously varying strain distribution, which gives rise to a gradient direct bandgap profile.

Couples of Fe-N4 site and non-coordinated boron atom are designed to reduce the energy barrier of the reversible conversion of imines as byproduct in catalytic oxidation reaction of amines, considerably promoting the selectivity to nitriles (> 99.9%) under mild conditions. The optimized FeNC+B also provides a turn-over frequency (TOF) value of 21.6 molbenzonitrile·molFe−1·h−1 (100 °C), outperforming benchmarked nonnoble-metal-based homogeneous catalyst by a factor of 3.4.
