Article Abstract
Layered double hydroxides (LDHs)-based electrocatalysts, owing to their structural designability and interface responsiveness, have emerged as promising candidates for constructing efficient non-noble metal electrocatalysts. Through interfacial structural modulation, defect engineering facilitates the exposure and activation of catalytic sites, ultimately boosting the electrocatalytic performance of LDH systems. This review analyzes the principle of interface structure design in LDHs driven by defect engineering. Then, the multidimensional regulatory mechanisms of defect engineering on the atomic arrangement, electronic structure evolution, adsorption and desorption behaviors, active site reconstruction, and stability control in the catalytic interface of LDHs are systematically discussed. Finally, this paper summarizes the key challenges that remain to be addressed and provides theoretical support and direction guidance for the construction of defect engineering-driven interfacially regulated efficient electrocatalytic systems.

Distraction osteogenesis (DO) is an endogenous bone tissue engineering technique that harnesses the regenerative potential of bone and has been widely applied in limb lengthening, bone defect repair, and craniofacial reconstruction. The DO procedure consists of three distinct phases: the latency phase, the distraction phase, and the consolidation phase, each characterized by unique biological processes. In recent years, increasing attention has been directed toward the role of the immune system during DO.

This study highlights the biomedical relevance of injectable TS (tannic acid-silk fibroin)-Mg/Sr hydrogels in alveolar bone repair, particularly their prospective role as carriers for stem cells from the apical papilla (SCAPs) in tissue regeneration. By utilizing self-assembling silk material, noted for its favorable handling properties, we present a useful approach for single-wall bone defects, such as bone fenestration and fractures in the oral cavity. Furthermore, our findings regarding the involvement of the TRPM7 ion channel indicate a possible regulatory pathway for improving alveolar bone defect repair.

Nanoparticles in their pure colloidal form synthesized by laser-assisted processes such as laser ablation/fragmentation/irradiation/melting in liquids have attained much interest from the scientific community because of their specialties like facile synthesis, ultra-high purity, biocompatibility, colloidal stability in addition to other benefits like tunable size and morphology, crystalline phases, new compounds and alloys, and defect engineering. These nanocolloids are useful for fabricating different devices mainly with applications in optoelectronics, catalysis, sensors, photodetectors, surface-enhanced Raman spectroscopy (SERS) substrates, and solar cells. In this review article, we describe different methods of nanocolloidal synthesis using laser-assisted processes and corresponding thin film fabrication methods, particularly those utilized for device fabrication and characterization.

In confluent cell monolayers, patterns of cell forces and motion are systematically altered near topological defects in cell shape. In turn, defects have been proposed to alter cell density, extrusion, and invasion, but it remains unclear how the defects form and how they affect cell forces and motion. Here, we studied +1/2 defects, and, in contrast to prior studies, we observed the concurrent occurrence of both tail-to-head and head-to-tail defect motion in the same cell monolayer.
