Summary: By utilizing 1,1'-ferrocene dicarboxylic acid as a chelating and surface protection ligand, we have synthesized multi-nuclear indium oxide clusters with varying nuclear sizes, including heptanuclear and thirteen-nuclear clusters. These clusters possess labile coordination sites, allowing for structural modification and self-assembly, resulting in the formation of various cluster structures.

Summary: In this study, Ag clusters were collaboratively protected by hydrophobic Ti-oxo clusters and alkyne ligands, overcoming their inherent instability. This threefold protection resulted in superhydrophobicity and excellent ambient stability of the Ag nanoclusters, leading to solid-state optical limiting characteristics.

Summary: The study investigated the composite photocatalyst Bi12TiO20/Bi4Ti3O12 as an alternative to titanium dioxide, utilizing pulsed DC reactive magnetron co-sputtering to produce polycrystalline thin films. Results showed considerably higher efficiency of the composite photocatalyst compared to TiO2, with performance increasing over repeated usage, attributed to the presence of oxygen vacancies and longer lifetimes of photogenerated species.

Summary: This study reports the assembly of two cyclic titanium-oxo clusters with ferrocene connectors and demonstrates that ferrocene ligands can serve as both connectors and photosensitizers to improve the light absorption behavior of the resulting compounds. The research opens a new way for the geometric assembly of titanium-oxo clusters and contributes to the deep understanding of the structure-property relationships of sensitized Ti-based materials.

Summary: In this study, a stable and highly effective antibacterial and anti-inflammatory Ag-Titanium-oxo-cluster (Ag-TOC, Ag9Ti4) was developed through one-step solvothermal method by introducing silver and salicylic acid. The Ag9Ti4 cluster was incorporated into a dopamine-containing hydrogel system, which exhibited excellent antibacterial and photothermal properties in vitro. Furthermore, the Ag9Ti4 hydrogel system demonstrated superior anti-inflammatory and wound healing ability under NIR condition in vivo. The construction of the antibacterial, photothermal, and stable Ag-TOC hydrogel system provides a new strategy for expanding the biomedical applications of TOCs.

Summary: A series of BiO(ClBr)(0.5-x/2)I-x solid solutions were prepared using a facile refluxing synthesis and applied as photocatalysts for the degradation of organic pollutants. The synthesized solid solutions are constructed by nanoplates which transform into nanosheets for increasing iodine ions contents. Introducing iodine ions significantly decreased the optical bandgap of the obtained solid solutions. The solid-solution at x=0.2 showed the highest photocatalytic activity with a decomposition efficiency of 92.6% for 120 mins of reaction under LED irradiation, surpassing the performance of pure sample and BiOCl0.5Br0.5. This enhancement in photocatalytic performance was attributed to the effective separation of photo-induced electron-hole pairs.

Summary: The study explores the immobilization of photocatalytic particles in a continuous flowing system using double inverse-opal (DIO) structures. Increasing macropore size enhances the decomposition rate of organic dye due to high diffusion rate, but excessive increase can lower the rate due to light attenuation. These novel immobilized photocatalytic DIO-structured particles can be used by tuning particle size, macropore size, and DIO thickness.
