Circularly polarized light is incident on a nanostructured chiral meta-surface. In the nanostructured unit cells whose chirality matches that of light, superchiral light is forming and strong optical second harmonic generation can be observed.

A flexible single crystalline PMN-PT piezoelectric energyharvester is demonstrated to achieve a self-powered artificial cardiac pacemaker. The energy harvesting device generates a short-circuit current of 0.223 mA and an open-circuit voltage of 8.2 V, which are enough to meet the standard for not only charging commercial batteries but also stimulating heart without an external power source.

Novel structure-engineered amorphous oxide semiconductor thin-film transistors using a solution process to overcome the trade-off between high mobility and other parameters (i.e., on/off ratio, sub-threshold voltage swing, threshold voltage and so on) are proposed. We successfully demonstrate high performance confining structure-engineered AOS TFTs, which utilize a specially-designed layer with ultra-high density and high electron mobility.

Fabricated adhesives are demonstrated to support high loads while maintaining easy release on a variety of “real world” surfaces. These adhesives consist of simple elastomers and fabrics without nano or micron scale features, yet they surpass the adhesive force capacity of live Tokay geckos and can be scaled to large sizes.

Tungsten oxide quantum dots (QDs) with an average size down to 1.6 nm have been developed, serving as a new class of promising electrode materials, which yield efficient and fast electron/ion transport in charging/discharging process. With a visually impressive display, the QDs present coloration/bleaching times within 1 s, which is much superior to inorganic analogues and even competitive to organic related materials.
