In this work, we explore the use of mica as a substrate for flexible memristor devices. We employ the scotch tape exfoliation technique to peel the mica, which is made possible due to its perfect cleavage along the basal plane. The mica substrate allows for memristor devices with superior flexibility and thermostability, which may potentially lead to the realization of high-temperature memristors for application in biologically-inspired computing systems.

With the advantages of amorphous characteristics, optimal Fe doping contents, and in situ formation of active borate-enriched NiFeOOH layers during water oxidation, ultrafine amorphous NiFeB nanoparticles proved to be highly efficient oxygen-evolving catalysts for water splitting at a wide range of pH values (7–14).

High metallic phase concentration ultrathin ternary Mo1–xWxS2 nanosheets were successfully synthesized for the first time. The metallic phase concentration, together with the enlarged and distinct interlayer spacing, can be regulated by using different Mo/W atomic ratios, and the optimized catalyst shows obvious advantage in the electrochemical water splitting reaction.

We established a simple strategy to fabricate mechanically robust and thermally stable, hierarchically lotus-like super-hydrophobic nanostructures showing omnidirectional antireflective (AR) performance with tunability in the desired wavelength range. This approach is practically applicable in different optic and optoelectronic devices including windshields, display panels, eyeglasses, solar cells, and windows of high rise buildings.

Since its discovery, the direct imaging and determination of the crystal structure of few-layer graphdiyne has proven difficult. In this work, we successfully employed low-voltage transmission electron microscopy with low current density to realize the direct imaging of graphdiyne and confirmed that the structure of an as-synthesized graphdiyne nanosheet is crystalline, with six-layer thickness and ABC stacking.

Novel trilayer hybrid photodetectors comprising n-type Si wafer, TiO2 interlayer, and perovskite film are demonstrated. The heterojunction photodetectors exhibit broad photoresponse, high response speed, and a higher on/off ratio, when compared to pristine Si and perovskite based devices.

The effects of DNA nucleobases on the photoluminescence (PL) emission of monolayer WS2 (1L WS2) grown by chemical vapor deposition are revealed. The PL modulation is attributed to the p-type doping of WS2 via charge transfer, and this was confirmed using both optical and electrical measurements.
