Article Abstract

The capture of radioactive iodine (129I or 131I) is of significant importance for the production of nuclear power and the treatment of nuclear waste. In recent years, crystallized porous materials have been extensively investigated to achieve highly effective adsorption of radioactive iodine. Herein, by using the hydrothermal method, a Ni cluster-based framework () was successfully constructed through a self-assembly process. Driven by the stacking interactions between -electron-rich benzimidazole groups, [NiS] clusters stack in a lattice, forming a porous framework with proper channels, rendering compound as an ideal adsorbent for iodine. Compound delivered a capability of iodine adsorption (2.08 g g- and 560 mg g- for gaseous and solution iodine, respectively) with stable cyclability.

With the rapid development of the nuclear medicine business worldwide, the removal of iodine-131 from specific contaminated environments to protect public health has important application prospects. In this study, the surface decontamination mechanism of Ce(IV)/HNO3 as a decontaminant for iodine-131-contaminated nonmetallic materials was investigated by using an orthogonal experimental method and scanning electron microscopy (SEM). During the preparation experiments with the contaminated materials, both quartz glass and ceramics reached peak activity concentration levels at 4 h of adsorption (contamination) by using immersion; the decontamination factor (DF) was selected as the test index for the decontamination experiments.

Non-steroidal anti-inflammatory drugs (NSAIDs) residues pose a potential threat to aquatic ecosystems and food safety. In this work, novel imine bond/pyridine nitrogen-rich magnetic microporous organic networks (MMONs-Br and MMONs-I) were synthesized via a facile one-pot strategy using brominated and iodinated precursors for the detection of NSAIDs in fish. Brunauer-Emmett-Teller analysis revealed a striking 11-fold difference in specific surface areas between the two materials (MMONs-Br: 293.

Background: Micronutrient deficiencies are common in patients undergoing maintenance hemodialysis (MHD), potentially contributing to adverse clinical outcomes. Hemodiafiltration with endogenous reinfusion (HFR) integrates convection, diffusion, and adsorption, potentially preserving essential nutrients better than traditional online hemodiafiltration (HDF). This study aimed to compare the acute effects of HFR and HDF on serum micronutrient concentrations in MHD patients.

"Fight Fire with Fire": Trace-Water-Induced Controllable Synthesis of Hydrophobic Armors to Stabilize Metal-Organic Cage-Based Crystalline Frameworks.

Small

September 2025

Department State Key Laboratory of Materials-Oriented Chemical Engineering, Jiangsu National Synergetic Innovation Center for Advanced Materials (SICAM), College of Chemical Engineering, Nanjing Tech University, Nanjing, 210009, China.

Metal-organic cage-based crystalline frameworks (MCFs) are distinguished for high porosity and diverse functionality, while their applications are constrained by degradation in wet environments. Inspired by the "fight fire with fire" method in traditional Chinese medicine, trace-water-induced synthesis of armors is proposed to stabilize MCFs. Water at ppm concentration is enriched on the hydrophilic surface of MCFs, and then polymerizes with diisocyanate under the catalysis of MCFs to form hydrophobic shells.

Obtaining direct structural evidence to elucidate the intricate interactions between iodine and adsorbents remains a significant challenge in the development of more effective iodine capture platforms. To address this issue, we report a 2D Co-tib MOF with adaptive interlayer cages that enable precise iodine binding via synergistic I···π, I···H-phenyl, and I···N halogen bonds, as directly observed by single-crystal XRD. Importantly, the 1D pores formed by the Co-tib layered structure enhance the diffusion of I, facilitating its adaptive binding.
