Abstract The sp 2 nature of graphene endows the hexagonal lattice with very high theoretical stiffness, strength and resilience, all well-documented. However, ultimate stretchability has not yet been demonstrated due to difficulties in experimental design. Here, directly performing situ tensile tests a scanning electron microscope after developing protocol for sample transfer, shaping straining, we report elastic properties free-standing single-crystalline monolayer grown by chemical vapor...
The iontronic pressure sensor achieved an ultrahigh sensitivity (Smin > 200 kPa-1, Smax 45,000 kPa-1). exhibited a broad sensing range of over 1.4 MPa. Pseudocapacitive using MXene was proposed. Flexible sensors are unprecedentedly studied on monitoring human physical activities and robotics. Simultaneously, improving the response flexible is great challenge, which hinders devices' practical application. Targeting this obstacle, we developed Ti3C2Tx-derived (TIPS) by taking advantages high...

A high‐quality E‐skin platform simultaneously monitor multiple physiological metabolic biomarkers without introducing discomfort or irritation is an unmet medical need. Conventional E‐skins are either monofunctional made from elastomeric films do not include key synergistic features natural skin, such as...
Flexible fiber-shaped supercapacitors (FSSCs) are recently of extensive interest for portable and wearable electronic gadgets. Yet the lack industrial-scale flexible fibers with high conductivity capacitance low cost greatly limits its practical engineering applications. To this end, we here present pristine twisted carbon (CFs) coated a thin metallic layer via electroless deposition route, which exhibits exceptional ∼300% enhancement superior mechanical strength (∼1.8 GPa). Subsequently,...
Abstract High strength and high ductility are often mutually exclusive properties for structural metallic materials. This is particularly important aluminum (Al)-based alloys which widely commercially employed. Here, we introduce a hierarchical nanostructured Al alloy with structure of nanograins surrounded by nano-sized glass (MG) shells. It achieves an ultrahigh yield 1.2 GPa in tension (1.7 compression) along 15% plasticity (over 70% compression). The MG phase facilitates such impeding...

Abstract A “cooling–contraction” method to separate large‐area (up 4.2 cm in lateral size) graphene oxide (GO)‐assembled films (of nanoscale thickness) from substrates is reported. Heat treatment at 3000 °C of such free‐standing macroscale yields highly crystalline “macroassembled nanofilms” (nMAGs) with 16–48 nm thickness. These nMAGs present tensile strength 5.5–11.3 GPa (with ≈3 µm gauge length), electrical conductivity 1.8–2.1 MS m −1 , thermal 2027–2820 W K and carrier relaxation time...
