Metal oxide/graphene nanocomposites are emerging as one of the promising candidate materials for developing high-performance gas sensors. Here, we demonstrate sensitive room-temperature H2S sensors based on SnO2 quantum wires that anchored reduced graphene oxide (rGO) nanosheets. Using a one-step colloidal synthesis strategy, morphology-related confinement can be well-controlled by tuning reaction time, because steric hindrance effect rGO. The as-synthesized wire/rGO spin-coated onto...
Slippery and hydrophilic surfaces find critical applications in areas as diverse biomedical devices, microfluidics, antifouling, underwater robots. Existing methods to achieve such rely mostly on grafting polymer brushes or coating hydrogel layers, but these suffer from several limitations. Grafted are prone damage do not provide sufficient mechanical compliance due their nanometer-scale thickness. Hydrogel coatings applicable only for relatively simple geometries, precluding use the with...
Abstract The adhesion of soft connective tissues (tendons, ligaments, and cartilages) on bones in many animals can maintain high toughness (∽800 J m −2 ) over millions cycles mechanical loads. Such fatigue-resistant has not been achieved between synthetic hydrogels engineering materials, but is highly desirable for diverse applications such as artificial cartilages tendons, robust antifouling coatings, hydrogel robots. Inspired by the nanostructured interfaces tendons/ligaments/cartilages...
Fabrication of unconventional energy storage devices with high stretchability and performance is challenging, but critical to practical operations fully power-independent stretchable electronics. While supercapacitors represent a promising candidate for energy-storage devices, existing are limited by their low stretchability, complicated fabrication process, cost.

Cerebral aneurysms and brain tumors are leading life-threatening diseases worldwide. By deliberately occluding the target lesion to reduce blood supply, embolization has been widely used clinically treat cerebral tumors. Conventional is usually performed by threading a catheter through vessels lesion, which often limited poor steerability of in complex neurovascular networks, especially submillimeter regions. Here, we propose magnetic soft microfiberbots with high steerability, reliable...
Abstract Nonhealing diabetic wounds are predominantly attributed to the inhibition of angiogenesis, re‐epithelialization, and extracellular matrix (ECM) synthesis caused by hypoxia. Although oxygen therapy has demonstrated efficacy in promoting healing, its therapeutic impact remains suboptimal due unsustainable oxygenation. Here, this work proposes an oxygen‐releasing hydrogel patch embedded with polyethylene glycol‐modified calcium peroxide microparticles, which sustainably releases for 7...
