Currently, the typical challenges that manufacturing enterprises faced are lack of timely, accurate and consistent information things (resources) during execution. Real-time visibility traceability allows decision makers to make better-informed shop-floor decisions. In this article, a real-time capturing integration architecture internet (IoMT) is presented provide new paradigm by extending techniques IoT field. Under its key components, such as operators, machines, pallets, materials etc....
Current work explored solid-state additive manufacturing of AZ31B-Mg alloy using friction stir deposition. Samples with relative densities ≥ 99.4% were additively produced. Spatial and temporal evolution temperature during deposition was predicted multi-layer computational process model. Microstructural in the fabricated samples examined electron back scatter diffraction high-resolution transmission microscopy. Mechanical properties evaluated by non-destructive effective bulk modulus...

Abstract Zwitterionic hydrogels exhibit great potential in biomedical applications due to their antifouling properties and biocompatibility. However, the single‐network structure of pure zwitterionic leads a low toughness strength, limiting application fields. In this work, high entanglement sulfobetaine methacrylate‐dopamine hydrogel (SBMA‐DA‐PE) with cross‐linker content monomer concentration is prepared by using dopamine oxidative radical polymerization method. Compared regular hydrogel,...
