A multifunctional wearable tactile sensor assisted by deep learning algorithms is developed, which can realize the functions of gesture recognition and interaction. This fusion a triboelectric nanogenerator piezoelectric to construct hybrid self-powered with higher power density sensibility. The generation performance characterized an open-circuit voltage VOC 200 V, short-circuit current ISC 8 μA, 0.35 mW cm-2 under matching load. It also has excellent sensibility, including response time 5...
A novel vacancy-induced microstrain engineering strategy is developed in FeCoNiCrPt high-entropy alloy, enabling high activity and long lifetime hydrogen evolution under universal pH conditions.
Platinum-based catalysts are widely used in hydrogen evolution reactions; however, their applications restricted because of the cost-efficiency trade-off. Here, we present a thermodynamics-based design strategy for synthesizing an Al73Mn7Ru20 (atomic %) metal catalyst via combinatorial magnetron co-sputtering. The new electrocatalyst is composed ~2 nanometers medium-entropy nanocrystals surrounded by amorphous regions. exhibits exceptional performance, similar to that single-atom and better...
To alleviate the mechanical instability of major shear bands in metallic glasses at room temperature, topologically heterogeneous structures were introduced to encourage multiplication mild bands. Different from former attention on topological structures, here we present a compositional design approach build nanoscale chemical heterogeneity enhance homogeneous plastic flow upon both compression and tension. The idea is realized Ti-Zr-Nb-Si-XX/Mg-Zn-Ca-YY hierarchically nanodomained amorphous...
The transformation induced plasticity phenomenon occurs when one phase transforms to another during plastic deformation, which is usually diffusionless. Here we present elemental partitioning-mediated crystalline-to-amorphous quasi-static in an alloy form of a Cr-Ni-Co (crystalline)/Zr-Ti-Nb-Hf-Ni-Co (amorphous) nanolaminated composite, where the constitute elements two phases have large negative mixing enthalpy. Upon atomic intermixing between adjacent amorphous and crystalline due...
Higher strength and higher ductility are desirable for structural materials. However, ultrastrong alloys inevitably show decreased strain-hardening capacity, limiting their uniform elongation. We present a supranano (<10 nanometers) short-range ordering design grain interiors boundary regions, respectively, in fine-grained based on vanadium, cobalt, nickel, with additions of tungsten, copper, aluminum, boron. The pronounced boundary-related strengthening ductilization mechanism is realized...
Recently, heterogeneous structured materials have attracted considerable attention due to their excellent mechanical properties. In this work, a heterostructured Al–AlN/Al–Mg laminated composite was successfully prepared by accumulative roll-bonding (ARB), and the microstructural evolution tensile properties both at room temperature under liquid nitrogen were investigated systematically. It is found that distribution of AlN particles in Al–AlN layer has been optimized be more uniform avoid...
A new Al–Si–Mg alloy was prepared and refined by C-doped TiB2 (C-TiB2) strengthened SiC, the effects of microstructure configuration on mechanical properties alloys were investigated in this study. The results show that eutectic Si reinforcing particles distribute a network cast with globular grains. In addition, distribution is streamlined along extrusion direction after hot extrusion. beneficial to ductility alloy, elongation which almost twice possesses higher strength. phase can better...
In this work, novel TiC particles doped by trace amounts of B, referred to as TiCB, were introduced an Al-Mn alloy with the Al-TCB master alloy. The effects TiCB on solidification microstructure, extrusion behavior, and mechanical properties systematically studied. results showed that could significantly refine α-Al grains providing heterogeneous nucleation substrates hindering growth α-grains. For example, when amount added was 0.5 wt%, average grain size be refined a minimum 40.2 μm from...

Comprehensive analysis revealed that nano-AlN resulted in a significant modification eutectic Si by causing poisoning twin plane re-entrant edge growth restricting crystals. Correspondingly, morphology transformed from flaky to fibrous. Furthermore, synergy areas without particle was...
P-type Cu2O nanocrystals were deposited on n-type silicon nanowire arrays (Si NWs) to form core-shell heterojunction structure via a simple electroless deposition technique. Scanning electron microscopy, transmission microscope and x-ray diffraction utilized characterize the morphology of nanosystem. The reflectivity obtained measured by UV/vis spectrometry showed comparatively low in visible-light region, which implied good optical absorption performance. water splitting performance Si NWs,...
