Summary: A novel dual-curing procedure combining radical UV-initiated reaction and thermal thiol-epoxy reaction was developed in this work. Optimal thiol amount is essential for obtaining cross-linked materials with good mechanical performance and avoiding dripping of free monomers during storage. Glycidyl methacrylate in combination with trifunctional meth(acrylates) allows gelation in the 1st stage and acts as a covalent coupling between (meth)acrylates and epoxy networks.

Summary: In this paper, a rapid light-curing system was established to reduce the refractive index of cured films and enhance the interfacial adhesion between optical fiber and coatings. The low molar refractive index of fluorine atoms and the highly active oligomeric main resin were utilized to achieve this goal. The experimental results showed that the designed optical fiber coatings had adjustable refractive indices, high light transmittance, and improved curing rate.

Summary: A precise synthesis strategy is proposed to stabilize single atomic ruthenium on nickel vanadium layered double hydroxides (NiV-LDH) ultrathin nanoribbons support. The resulting NiVRu-R catalyst demonstrates superior catalytic properties for electrocatalytic hydrogen evolution reaction (HER) in alkaline media, outperforming the commercial Pt/C catalyst. The stability of NiVRu-R is maintained even after 5,000 cyclic voltammetry cycles, which is attributed to the Ru atomic sites stabilized on supports through the Ru-O-V structure.

Summary: Ionogels are promising materials for flexible electronics due to their continuous conductive phase, high thermal and chemical stability. However, a large amount of ionic liquid is required to get high conductivity, resulting in a sharp decline in the mechanical properties. Therefore, it is a great challenge to prepare ionogels with both high conductivity and mechanical properties, which is important for their practical applications.

Summary: Researchers constructed BaTiO3/TiO2@polypyrrole (PPy) composites with hollow multishelled structure (HoMS) to enhance the electromagnetic wave absorbing properties of BaTiO3-based absorbing material. BaTiO3/TiO2 HoMSs were prepared using TiO2 HoMSs as a template. FeCl3 was then introduced to initiate the oxidative polymerization of pyrrole monomer, successfully forming BaTiO3/TiO2@PPy HoMSs. The electromagnetic wave absorbing properties of BaTiO3/TiO2 HoMSs and BaTiO3/TiO2@PPy HoMSs with different shell numbers were investigated. The results show that BaTiO3/TiO2@PPy HoMSs exhibit improved microwave absorption, with tripled-shelled BaTiO3/TiO2@PPy HoMS having the most excellent absorbing performance.
