Programmable Guest‐Induced 5‐Phase‐Transition Topological Reconstructions of Cobalt Formate Metal–Organic Frameworks

Advanced Science, EarlyView.
A reversible five‐phase topological cycle is achieved in a minimalist cobalt formate metal–organic framework. The amorphous phase functions as a programmable reactive hub, selectively reconstructing into four distinct crystalline architectures through cationic templates, humidity, or CO2.

One-pot hydrothermal synthesis of reduced graphene oxide/zinc ferrite nanohybrids and its catalytic activity on the thermal decomposition of ammonium perchlorate

Journal of Saudi Chemical Society, 2019
Reduced graphene oxide/Zinc ferrite (rGO/ZnFe2O4) nanohybrids are successfully decorated on the surface of the rGO sheets through a simple, one-step hydrothermal method. ZnFe2O4 nanoparticles (NPs) are homogeneously anchored on the rGO sheets.

Tribochemical Surface Modification of Silicon

Chemistry – A European Journal, EarlyView.
Mechanical scribing activates silicon surfaces by generating reactive sites that spontaneously graft alcohol‐, thiol‐, and alkyne‐terminated molecules under ambient conditions. Within 10 s, high‐coverage, electroactive organic layers form without light, heat, or applied voltage, offering a rapid tribochemical route to functional silicon interfaces for ...
