AbstractHighly branched metallic nanostructures, which possess a large amount of catalyst active sites and surface-enhanced Raman scattering (SERS) hot spots owing to their large surface areas, multi-level branches, corners, and edges, have shown potential in various applications including catalysis

AbstractThis study demonstrates that a novel uniform magnetic field significantly improves the magnetofection of MG‑63 osteoblasts using low‑molecular‑weight linear PEI (MW 20 kDa) modified superparamagnetic iron oxide nanoparticles (PEI‑SPIO‑NPs). The PEI‑SPIO‑NPs exhibit optimal size, zeta potenti

AbstractTiO₂ is a low‑cost, environmentally benign material with excellent electrochemical potential. Its practical use in supercapacitor electrodes has been limited by high internal ion resistance and poor electrical conductivity. In this study, we employed atomic layer deposition (ALD) to fabricat

AbstractDespite half a century of progress in polyacrylonitrile (PAN)‑based carbon fiber technology, the precise chemical origins of the skin‑core heterogeneity remain poorly understood. Leveraging photo‑induced force microscopy (PiFM) – a nanoscale chemical imaging technique – we mapped the distrib
