Summary: The study demonstrates a feasible method to fabricate patchy silicon dioxide microspheres, which can be equipped with tailor-made polymeric materials as patches. The method relies on a solid-state supported microcontact printing (μCP) routine optimized for the transfer of functional groups to capillary-active substrates, introducing amino functionalities as patches to a monolayer of particles. Acting as anchor groups for polymerization, photo-iniferter reversible addition-fragmentation chain-transfer (RAFT) is used to graft polymer from the patch areas. The protocol promises a vast degree of freedom in engineering the surface properties of highly functional patchy particles, making it a platform technology for the fabrication of particles with locally precisely formed patches.

Summary: An addition-fragmentation monomer (AFM) is utilized in 3D printer resins to reduce shrinkage during polymerization. The AFM enables reversible network formation and improves mechanical performance. The AFM is synthesized via catalytic chain transfer polymerization (CCTP) and characterized using NMR and size exclusion chromatography (SEC). The incorporation of AFM as a crosslinker allows for rapid reversible covalent bond formation and reduces both polymerization shrinkage and stress buildup.

Summary: A robust aggregation-induced emission luminogen photoaddition-fragmentation chain transfer (PET-RAFT) polymerization was investigated, resulting in the preparation of a variety of well-defined polymers with narrow polydispersities (D < 1.20). The use of low concentrations of a donor-acceptor (D-A) type aggregation-induced emission luminogen as a photocatalyst enabled polymerization under visible light at ambient temperature. Previous studies have mainly focused on organic solvents, with fewer investigations conducted in aqueous environments. This study successfully demonstrated the polymerization strategy in water with or without oxygen, leading to the synthesis of structure-controlled polymers. Furthermore, the fluorescence intensity of DCDPP-2TPA increased linearly with the degree of polymerization.

Summary: Vanadium dioxide (VO2) is considered as a promising material for smart windows. However, its real application is hindered by several limitations. In this study, core-shell structured VO2@PMMA-b-PHFBMA nanoparticles with excellent properties were prepared using a RAFT polymerization method. The addition of a F-containing polymer shell improved the stability and compatibility of the VO2 nanoparticles. Furthermore, a photochromic and hydrophobic copolymer was synthesized and coated onto the VO2 nanoparticles to create an energy-saving composite film. The composite film showed high solar modulation efficiency, making it a highly promising application for smart windows.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.
