Abstract There is an emergent demand for high-flexibility, high-sensitivity and low-power strain gauges capable of sensing small deformations vibrations in extreme conditions. Enhancing the gauge factor remains one greatest challenges sensors. This typically limited to below 300 set when sensor fabricated. We report a strategy tune enhance sensors based on Van der Waals materials by tuning carrier mobility concentration through interplay piezoelectric photoelectric effects. For SnS 2 we up...
Strong metal–support interactions (SMSIs) play a crucial role in the catalytic performance of supported metal catalysts. Researchers hypothesize that there is migration support over preexisting nanoparticles during pretreatment. In present work, distinct mechanism generating an SMSI by co-reduction oxide interphase evaluated Ru/TiO2 Formation RuxTi1–xO2 augmented facile manner increasing calcination temperature catalysts, whereas encapsulation TiOx overlayer on metallic Ru occurs subsequent...
A method is developed to synthesize surface-enhanced Raman scattering (SERS) materials capable of single-molecule detection, integrated with a microfluidic system. Using focused laser, silver nanoparticle aggregates as SERS monitors are fabricated in channel through photochemical reduction. After washing out the monitor, irradiated again by same laser. This key step leads full reduction residual reactants, which generates numerous small nanoparticles on former nanoaggregates. Consequently,...
SnSe2 is an anisotropic binary-layered material with rich physics, which could see it used for a variety of potential applications. Here, we investigate the gas-sensing properties using first-principles calculations and verify predictions gas sensor made few-layer grown by chemical vapor deposition. Theoretical simulations indicate that electrons transfer from to NO2, whereas direction charge opposite NH3. Notably, flat molecular band appears around Fermi energy after NO2 adsorption induced...
Layered materials are highly attractive in gas sensor research due to their extraordinary electronic and physicochemical properties. The development of cheaper faster room-temperature detectors with high sensitivities especially the parts per billion level is main challenge this rapidly developing field. Here, we show that sensitivity NO2 (S) can be greatly improved by at least two orders magnitude using an n-type electrode metal. Unconventionally for such devices, ln(S) follows classic...
Abstract Triboelectric nanogenerators (TENGs) are used to harvest high entropy energy. To optimize the energy harvesting, storage and effective utilization, a critical part is power management system (PMS), which requires an ideal electrical switch as key component. However, current technologies cannot adapt enhance charging for four operation modes of TENG simultaneously. Herein, flexible film‐discharge‐switch (FDS), delivering averaged charge‐enhance factor over 100 under TENG, compared...
Abstract The multi‐operating robustness of triboelectric nanogenerators (TENGs) is still an awkward issue that must be solved to achieve practicality and industrialization.

Ru-based catalysts feature an intrinsic activity toward NH3 decomposition, while their catalytic mechanism associated with the interface support remains elusive. Herein, interfacial regulation of Ru by TiO2 via strong metal–support interactions (SMSI), i.e., Ru/TiO2, enhanced decomposition can be realized a turnover frequency hydrogen production 2-fold higher than that on Ru/SiO2. With characterizations and density functional theory calculations, newly generated Ru/TiO2–x electron-rich sites...
