Summary: The nucleotide incorporated zeolitic imidazolate frameworks (NZIF) demonstrated superior adsorption capacity for organic dye molecules compared to ZIF-8, with a maximum adsorption capacity 6-5 times higher. The presence of introduced nucleoside monophosphate enabled NZIF to function under acidic conditions and enhanced the adsorption capacity through hydrogen bonding, stacking interaction, and electrostatic forces. This study offers a new avenue for designing porous materials for environmental remediation.

Summary: A highly efficient adsorbent (TNSs@PDA@CuHCF) was synthesized by coating titanate nanosheets with polydopamine and loading copper hexacyanoferrate. This adsorbent exhibited excellent adsorption capacity for Cs(I) from aqueous solution (374.53 mg/g at 298 K). The adsorption behavior of Cs(I) on TNSs@PDA@CuHCF was well described by the Langmuir isotherm model and the pseudo-second-order kinetic model. Thermodynamic analysis revealed that the adsorption of Cs(I) was a spontaneous and endothermic process. The interaction between Cs(I) and the adsorbent was primarily attributed to ion exchange.

Summary: Chitosan crosslinked with potassium tripolyphosphate (CTPP) and monochlomacetic-acid-modified chitosan crosslinked with potassium tripolyphosphate (MCTPP) were synthesized for efficient removal of UO22+ from acidic radioactive effluents. The adsorption process was influenced by factors such as pH and adsorbent dose, and the adsorption mechanism was found to be an endothermic single-layer process. The synthesized composites showed high adsorption capacities for UO22+ and were minimally affected by common metal ions.

Summary: In this study, a novel porous organic polymer material, Imi-PPOPs-Br, was developed and showed excellent adsorption capacity, reusability, and selectivity for Au (III) in extracting gold from electronic waste. The adsorption mechanism was found to be due to the electrostatic interaction, strong binding of Au and N active sites, and reductive immobilization of Au (III) to Au (0). This study provides a new and facile strategy for constructing stable absorbents in environmental applications.

Summary: This study demonstrates how defects can be introduced into porous ionic polymers using a defect-engineering strategy, allowing for control of pore size distribution, specific surface area, chemical stability, and gas adsorption performance. The presence of controllable vacancies and porosity in polymers was investigated using solid-state nuclear magnetic technique, showing improved ammonia adsorption performance compared to neutral and defect-free polymers. The strong interactions between gas molecules and the PIP-X are reversible, displaying outstanding recyclable ability without structure collapse, making defective anionic polymers a versatile type of ion-exchange material for gas uptake.

Summary: In this study, we synthesized and characterized the first binary iron arsenide cluster anion, [Fe-3(As-3)(3)(As-4)](3-), which is present in both [K([2.2.2]crypt)](3)[Fe-3(As-3)(3)(As-4)] (1) and [K(18-crown-6)](3)[Fe-3(As-3)(3)(As-4)]center dot en (2). The cluster consists of an Fe-3 triangle with three short Fe-Fe bond lengths, and it is bridged by a 2-butene-like As-4 unit. DFT analysis of the electronic structure reveals a triplet ground state with direct Fe-Fe bonds stabilizing the Fe-3 core.

Summary: Two isomers of [Ge-9-In-Ge-9](5-) sandwich-type anion were synthesized by controlling chelating agents. Reaction with Mo(CO)(6) and Ni(COD)(2) yielded two new types of inorganic sandwich derivatives: a half-sandwich cluster [Ge-9-In-Mo(CO)(5)](3-) and an unsymmetrical sandwich-type cluster {[(Ni@Ge-9)In(Ni-0.648@Ge-9)]}(5-). The isolation of these derivatives demonstrates the reactivity of [Ge-9-In-Ge-9](5-) sandwich-type anion, providing insight for constructing new inorganic sandwich compounds.

Summary: This study investigates the influence of ligand structure on the extraction of Am3+ over Eu3+ in the efficient separation of trivalent actinides over lanthanides. Among the three ligands tested, N,N-diethyl-N',N',N'',N''-tetraoctylnitrilotriacetamide shows the highest extraction ability for Am3+. The study reveals that unsymmetrical NTAamides have higher extraction efficiency to Am3+ and relatively lower selectivity for Am3+ over Eu3+ than the symmetrical NTAamide due to steric hindrance.
