Summary: In this study, the impact of hydrogen bonding networks on the vibrational modes of the uranyl cation in hexavalent uranium materials was investigated. The synthesis and structural characterization of five novel compounds revealed that slight changes in crystalline packing and hydrogen bonding networks result in modifications of the vibrational modes, as observed by infrared and Raman spectroscopy.

Summary: This paper provides a review of the structural chemistry of organically templated uranyl sulfates and selenates. A total of 194 compounds have been identified, with crystal structures that include 84 different organic molecules. The study highlights the complex limitations in isomorphic substitution implementation and the rarity of isotypic phases. The combination of organic and oxyanion parts determines the overall structural architecture of the compounds, and changes in these parts can lead to the formation of rare and more complex topologies. Additionally, the crystal structures of three novel uranyl compounds templated by isopropylammonium cations are reported.

Summary: A new ditopic ligand [2,2'-(1,4-phenylene)bithiazole]-5,5'-dicarboxylic acid (H2TzPhTz) was synthesized and its crystal structure determination revealed an extended hydrogen-bond network. Reaction with ZnII and UVI salts yielded two coordination polymers, [Zn(TzPhTz)(H2O)(2)] (Zn_TzPhTz) and [UO2(TzPhTz)(DMF)].DMF (U_TzPhTz). Both polymers emit blue-green light in the solid state.

Summary: The reaction between UO2 (OAc) (2) .2H(2)O and the biologically inspired ligand H2L1 resulted in the formation of trinuclear uranyl complexes, which were isolated as Cs salts in good yield. Recrystallization in the presence of 18-crown-6 led to the formation of neutral ion pairs with alkali metal ions like Cs+, Rb+ and K+. X-ray investigations revealed the discrete trinuclear uranyl species in each complex, coordinating to the alkali metal ions through three uranyl oxygen atoms. Coordination behavior of H2L1 and H2L2 towards UO22+ was studied using NMR, UV/Vis spectroscopy and mass spectrometry, showing the in situ formation of the dianions in solution.

Summary: Polarized optical microscopy (POM), scanning electron microscopy (SEM), and synchrotron microbeam wide-angle X-ray diffraction (WAXD) were used to investigate the mechanisms of periodic assemblies leading to ring-banded crystal aggregates with light-grating capacity for iridescence in poly (1,4-butylene adipate) (PBA) modulated with poly (ethylene oxide) (PEO). It was found that the PBA crystal assembly forms a grating architecture with light-interference properties, similar to those found in nature.

Summary: In this study, a simple strategy was demonstrated for constructing low-tortuosity through-pores in both vertical and planar directions of electrodes by casting large particles into single-particle-layer electrodes. Through multi-scale characterizations and simulations, correlations between material/electrode structures, electrolyte permeability, polysulfide migration, and sulfur reactions were elucidated. The high-loading and dense sulfur cathode fabricated by this method delivers a high specific capacity at a very low electrolyte/sulfur ratio.

Summary: Keggin-type molybdo- and tungsto-phosphate polyoxoanions suffer from limited stability at low pH, but their stability can be improved by forming supramolecular complexes with cyclodextrins (CDs). Gamma-CD shows the strongest stabilization effect on these polyoxoanions, allowing them to remain intact at higher pH values. In addition, the stability enhancement of the complexes formed with smaller alpha- and beta-CDs is less pronounced.

Summary: The UiO family of metal-organic framework (MOF) materials is considered as one of the best choices for capturing gaseous iodine in nuclear power energy due to its properties like high specific surface areas, great iodine adsorption capacity, and good stability under nuclear accidents conditions. In this study, three UiO-67_NH2 samples with different metal contents were used to capture iodine, and Raman spectroscopy mappings were used to evaluate the different species. The results showed that UiO-67_NH2(Hf) compound had the best adsorption capacity, capturing 3428 g center dot mol(-1) of iodine, while UiO-67_NH2(Zr/Hf) and UiO-67_NH2(Zr) samples adsorbed 2835 g center dot mol(-1) and 1658 g center dot mol(-1) respectively. The spatial distribution of I-2 and I-3(-) along the crystals of UiO67_NH2 materials was correlated with the diffusion process of both species, improving the understanding of the mechanism responsible for iodine conversion and stabilization in UiO materials.

Summary: This paper reports the synthesis and characterization of six coordination complexes obtained by reacting [MoV2 O2S(2)](2+) clusters with bisthiosemicarbazone ligands containing flexible or rigid spacers. The nuclearity of the complexes was found to be controlled by the nature of the spacer between the thiosemicarbazone units, as revealed by structural characterization techniques. Flexible spacers resulted in binuclear complexes [MoV2 O2S2(L1-3)], while rigid spacers led to tetranuclear complexes [(MoV2 O2S2)(2)(L4-6)(2)].

Summary: This study investigates the use of chitosan hydrogel microspheres as a template for growing an extended network of MOF-type HKUST-1. Different drying methods (supercritical CO2, freeze-drying, and vacuum drying) were used to generate three-dimensional polysaccharide nanofibrils embedding MOF nanoclusters. The resulting HKUST-1@Chitosan beads exhibit uniform and stable loadings of HKUST-1 and were used for the adsorption of CO2, CH4, Xe, and Kr. The maximum adsorption capacity of CO2 was found to be 1.98 mmol center dot g(-1) at 298 K and 1 bar, which is significantly higher than those of most MOF-based composite materials. Based on Henry's constants, thus-prepared HKUST-1@CS beads also exhibit fair selectivity for CO2 over CH4 and Xe over Kr, making them promising candidates for capture and separation applications.

UiO-66-NH2 exhibits remarkable affinity for RuO4 capture, resulting in the highest RuO4 decontamination factor worldwide. The efficiency of UiO-66-NH2 can be attributed to its pore diameters well adapted for RuO4 capture and its conversion into stable RuO2.

Summary: By hybridizing TiO2 photocatalyst with CaCO3 as the wall material and using linseed oil as the core material, self-cleaning and self-repairing microcapsules were produced using in-situ precipitation. The microcapsules were evaluated for their morphology, chemical composition, thermal stability, and self-cleaning and self-repairing properties. Results showed that the microcapsules had a rough and spherical surface, along with excellent thermal stability and repeatability. Increasing the dosage of microcapsules significantly increased the degradation rate of methylene blue, while the self-repairing effect of micro-cracks became more evident. The optimal microcapsule dosage was found to be 7.0 wt%.
