Summary: A novel and facile method is developed to synthesize a three-dimensional fibrous scaffold with spatiotemporally defined patterns of simvastatin, which is optimized for angiogenesis-coupled osteogenesis. The electrospinning process of the 3D fiber deposition is demonstrated in detail through computer simulation. The functionalized 3D fibrous scaffolds induce biomineralization mimicking natural apatite layer. The as-fabricated 3D fibrous scaffolds loaded with simvastatin promote the osteogenic differentiation of human mesenchymal stem cells and angiogenesis in human umbilical vein endothelial cells.

Summary: This study employs a simple synthetic approach to disperse Rh atoms (Rh SAs) over the surface of interconnected Mo2C nanosheets embedded in a three-dimensional NixMoOy nanorod arrays (NixMoOy NRs) framework. The introduction of both isolated Rh SAs and NixMoOy NRs adjusts the electrocatalytic function of the host Mo2C towards efficient hydrogen evolution at pH-universal conditions. The proposed catalyst outperforms most recently reported transition metal-based catalysts, showing ultralow overpotentials and small Tafel slopes in acidic, neutral, and alkaline conditions, as well as remarkable long-term stability over all pH values.

Summary: The study introduces a controlled drug delivery system using polymeric magnetic nanoparticles. By applying an alternating magnetic field, the internal heating sources, magnetic nanoparticles, lead to an increase in temperature, triggering polymer transitions and releasing the entrapped drug. The drug-release mechanism is explained using different mathematical models. The results show that surface area changes are the main driving force for drug release, and the release mechanism is temperature-dependent.
