Ligand architecture and secondary‐sphere effects in a well‐defined cobalt(IV)–oxo complex

Bulletin of the Korean Chemical Society, EarlyView.
A well‐defined cobalt(IV)–oxo complex supported by a neutral tetraazamacrocyclic ligand is generated and fully characterized. The cobalt(IV)–oxo species exhibits electrophilic oxygen‐atom and hydrogen‐atom transfer reactivity, strongly modulated by protonation and secondary coordination sphere effects, providing new insight into structure–reactivity ...

Programmatic regulation of macrophage polarization by HAp@MXene nanocomposites to promote bone repair

BMEMat, EarlyView.
HAp@MXene nanocomposites could achieve the programmed regulation of macrophage polarization. They first induce M1 polarization through magnetoelectric induction to combat infection. Subsequently, controlled Ca2+ release drives M2 polarization to promote tissue regeneration. This dual mechanism accelerates bone defect repair and highlights the potential
