Role of Defects in the Paramagnetism of Fe-doped Cs2_{2}AgBiBr6_{6} Double Perovskite

By integrating single-crystal growth, electron paramagnetic resonance spectroscopy, and first-principles modeling, this study identifies Fe-doped Cs2_{2}AgBiBr6_{6} paramagnetism as arising from stable FeBi_{\rm Bi}-VBr_{\rm Br} impurity-vacancy complexes that act as orientation-sensitive spin probes of structural symmetry while influencing the material's optical properties.

Competition between clustering and dispersion of cobalt atoms on perovskite surfaces: SrTiO3(001) and KTaO3(001)

Using noncontact atomic force microscopy and photoelectron spectroscopy, this study reveals that cobalt atoms on SrTiO3(001) and KTaO3(001) perovskite surfaces exhibit a competition between remaining as dispersed ionic single atoms and undergoing annealing-induced clustering or subsurface incorporation, with the latter mechanism being more pronounced in SrTiO3.

Trichome entanglement enhances damage tolerance in microstructured biocomposites

This study demonstrates that leveraging the physical entanglement of helical *Spirulina* trichomes within a hydroxyethyl cellulose matrix significantly enhances the damage tolerance and mechanical strength of 3D-printed biocomposites by transitioning the failure mechanism from interfacial debonding to crack propagation through the entangled network.
