We have fabricated monolayer VSe2 film by molecular beam epitaxy and investigated its electronic state by angle-resolved photoemission spectroscopy (ARPES). We found an insulating gap on the entire Fermi surface in the charge-density-wave state as well as a pseudogap with a Fermi arc in the normal state. The present result opens a pathway toward understanding the interplay between the dimensionality and the novel physical properties in atomic-layer transition-metal dichalcogenides.

Janus electrode with asymmetric wettability possesses a proper aerophilic thickness which can not only capture and keep stable gas film as O2 reservoir shortening the O2 transport pathway to active sites in gas/solid/liquid interface, but also provides channels for ion transport. The special Janus film exhibited high oxygen reduction reaction (ORR) activity and rapid current growth, superior over the superaerophilic and superaerophobic electrodes.

The self-powered PtSe2/GaN heterojunction deep ultraviolet photodetectors are constructed by in-situ synthesis of two-dimensional (2D) PtSe2 thin films on GaN substrates, which exhibit excellent photoresponse properties to the deep ultraviolet with ultrahigh device performances.

By tuning the morphologies of precursors, the higher surface area and faster electron transfer of the final catalysts are afforded, proving the feasibility to enhance the catalytic property by tuning the morphology without changing the chemical composition.

Chemically-sensitive label-free photothermal induced resonance (PTIR) measurements provide insights into cytarabine drug distribution in individual liposomes (~80 nm diameter) with nanoscale resolution and enable liposome classification. A novel tapping-mode PTIR method based on heterodyne non-linear frequency mixing enables better characterization of the mechanically complacent (soft) liposomes and detection of ~103 cytarabine molecules (~1.7 zmol) encapsulated by a single liposome.

Porous nitrogen-doped carbon/MnO coaxial nanotubes (MnO@PNC) are prepared and used as a functional sulfur host for lithium-sulfur (Li-S) batteries. The host exhibits continuous conductivity network and excellent chemical interaction with polysulfides. When employed for cathodes of Li-S batteries, MnO@PNC-S shows superior rate performance and cyclability.

The ultrathin Rh wavy nanowire was studied as a highly effective methanol oxidation reaction (MOR) electrocatalyst with an ultrahigh electrochemically active surface area (ECSACO) of 144.2 m2/g and mass activity of 722 mA/mg at 0.61 V, which is considerably higher than many previously reported Rh and Pt-Based electrocatalysts at the same potential.

A novel method for suppressing Li dendrites via using Li phosphorous oxynitride (LiPON) modified Li anode and Li1.5Al0.5Ge1.5(PO4)3-poly (ethylene oxide)(Li bistrifluoromethane-sulfonimide)(LAGP-PEO (LiTFSI)) composite solid electrolyte in all solid-state Li battery is proposed. The LiPON thin film can form a stable interphase between Li metal anode and LAGPPEO (LiTFSI) solid electrolyte at a perfectly close contact. LiPON film can also prevent the Li metal anode from dendrite formation.
