Article Abstract
Titanium-based metal-organic frameworks (Ti-MOFs) hold great potential for applications in photocatalysis and other fields, owing to Ti's abundant reserves, low toxicity, and excellent photocatalytic and redox activity. However, Ti's strong affinity for oxygen often leads to Ti-MOFs being fully coordinated with ligands, which limits their catalytic and separation performance. Defect engineering provides an effective strategy to enhance the functionality of MOFs by introducing structural imperfections. Despite this, the synthesis of new Ti-MOFs and the incorporation of defects remain challenging due to the complex hydrolysis and reaction processes of Ti precursors and the uncertainty of Ti cluster formation. This review categorizes Ti-MOFs according to their diverse cluster structures, which play a key role in the development of new frameworks and defect engineering. It also examines various defect construction methods and their applications. Finally, insights from defect-engineered Zr-MOFs are discussed to inspire future advancements in the synthesis and application of defective Ti-MOFs.

Silicon carbide (SiC) membranes combine exceptional chemical, thermal, and mechanical stability but suffer from surface inertness that precludes functionalization. Conversely, MOFs offer unmatched molecular selectivity but are typically powders, severely limiting their practical use. To address this, we develop a generalizable route to fabricate ultrastable MOF@SiC membranes via sequential oxidation and acidification, creating abundant Si-OH sites on SiC surfaces that covalently bond with Zr-MOF crystals; the bonding mechanism between MOFs and substrates has been extensively studied.

Hyperglycemia-induced oxidative stress and inflammation critically impair diabetic bone defect repair. Here, a radially oriented microchannel scaffold (D-GSH@QZ) was developed via a directional freezing technique integrated with photo-cross-linking strategies. The scaffold was fabricated from gelatin methacryloyl, silk fibroin methacryloyl, and nanohydroxyapatite (HAp) to mimic the natural bone matrix, while incorporating quercetin-loaded ZIF-8 nanoparticles (Qu@ZIF-8) for pathological microenvironment modulation.

Sequential deposition technique is widely used to fabricate perovskite films with large grain size in perovskite solar cells (PSCs). Residual lead halide (PbI) in the perovskite film tends to be decomposed into metallic lead (Pb) under long-term heating or light soaking. Here, a chiral levetiracetam (LEV) dopant containing α-amide and pyrrolidone groups is introduced into the PbI precursor solution.

Recently, joint replacement surgery is facing significant challenges of patient dissatisfaction and the need for revision procedures. In-situ monitoring of stress stability at the site of artificial joint replacement during postoperative evaluation is important. Mechanoluminescence (ML), a novel "force to light" conversion technology, may be used to monitor such bio-stress within tissues.
