Employing a facile electrochemical reduction strategy, a self-supported MoOx-stabilized ultrafine palladium electrocatalyst on carbon cloth (MoOx-Pd/CC) was acquired to attain excellent catalytic efficiency for the electrochemical hydrogen evolution reaction (HER) in acidic condition.

Plasmonic gold nanochains (Au NCs) are embedded in an elastic polyvinylpyrrolidone (PVP) film, which can be simultaneously and reversibly tuned by mechanical deformation of the PVP film. This plasmonic film can serve as a sensitive and selective surfaceenhanced Raman scattering (SERS) platform for quick analysis of small molecule analytes in complex biological samples and food, without any pretreatment process.

This work unravels the underlying mechanism of optothermal tweezers at the atomistic level: The trapping of tiny objects is dominated by the opto-thermoelectric effect arising from water polarization and charge separation. The atomistic view guides us on the development of new types of optothermal tweezers with enhanced performance.

Atomic-scale three-dimensional (3D) nanostructures are directly visualised with a maximum depth of 6 atomic layers; in-situ observation unveils the growth of atomic-scale active sites in the form of twinning. Active site utilisation ratio is important to build double layers for efficient charge transfer.

By developing a physical model and an analytical model, we identify that the positive aging of quantum-dot light-emitting diodes (QLEDs) is mainly attributed to the suppression of hole leakage current that is resulted from the passivation of ZnMgO defects. To fully take the advantage of positive aging, a new encapsulation method is proposed, which improved the device lifetime by 6.0 folds.
