Summary: The pyrolysis of MOFs is a widely used method to generate hierarchical structures with metal nanoparticles embedded in a porous carbon matrix. In this study, in situ environmental transmission electron microscopy was used to observe the real-time formation and evolution of porous carbon decorated with metal species during the pyrolysis of zeolitic imidazolate framework-67 encapsulated with carbon dots. The migration of cobalt, the flow of aggregates, and the growth of carbon nanotubes were observed at the nanoscale. Experimental studies revealed the synergistic effect between doped graphite nitrogen and confined cobalt nanoparticles for enhanced catalytic performance.

Summary: The Sol-gel method was used to prepare a Si-Ti-epoxy organic-inorganic hybrid composite sol, which was cured on the carbon steel surface to form a transparent film with excellent electrochemical protection performance and hydrophobicity. The Si-Ti-epoxy hybrid film has a denser structure, higher impedance modulus, and lower corrosion current density compared to a double-thick epoxy film.

Summary: Near infrared (NIR) light has high transparency in biological tissue, and recent advances in NIR fluorophores have enabled effective use of the NIR optical window for in vivo bioimaging and photodynamic therapy. This review focuses on the development of hybrid nanostructures by utilizing the polarity and vibrational energy of ions and molecules surrounding the luminescence centers, with the aim of reducing heat emission and achieving bright luminescence. The guidelines proposed in the review are based on the multiphonon relaxation theory and emphasize the importance of surrounding luminescence centers with ions with low vibrational energy or molecules with small chemical polarity.

Summary: Organic-inorganic perovskite materials have shown excellent performance and competitiveness in high-performance photovoltaic and optoelectronic devices. Lead-halide perovskites with broadband emission have attracted interest for solid-state lighting, but their commercial exploitation is hindered by lead toxicity. In this study, a lead-free copper(I)-iodine hybrid was synthesized and its crystal structure and optical properties were investigated. The results show that this lead-free hybrid has potential applications in solid-state lighting and other perovskite opto-electronic devices.
