Summary: The study observed significant changes in the structural properties of hausmannite due to cobalt substitution, while manganite showed little to no effect. Both minerals exhibited accelerated release of manganese and cobalt in reductive dissolution, with most of the cobalt remaining in the mineral structure. Only hausmannite showed increased oxidation of As(III) to As(V) with increased cobalt substitution.

Summary: In this study, a novel oxidation-sorption bifunctional material UiO-66-Cl was successfully developed for efficient removal of highly migratory and toxic As(III) contamination in water. The UiO-66-Cl exhibited high removal efficiency across a broad pH range and was hardly affected by common anions and natural organic matter. The exhausted UiO-66-Cl could be easily regenerated for repeated use.

Summary: This study reports the capture and immobilization of gaseous RuO4 using a porous metal-organic framework (UiO-66-NH2) for the first time. 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: This study investigates the effects of nickel ions on the physicochemical properties and reactivities of hausmannite. The synthesized Ni-containing nanocomposites exhibit higher adsorption capacity and larger specific surface areas compared to pure hausmannite. These nanocomposites can quickly remove arsenic from water through oxidation, adsorption, and fixation. Arsenic immobilized on the mineral surfaces forms bidentate binuclear complexes with active Mn/Ni sites.

Summary: MgCoxNi1-xSiO4 (0.0 < x < 1.0) solid solutions with an olivine structure were synthesized via the chemical coprecipitation method, and materials with a smaller M(II) (M = Co, Ni) amount than Co2SiO4 and Ni2SiO4 compounds were obtained. The distribution of Co(II) and Ni(II) ions in the solid solutions were found to be random at 1200 degrees C, with a higher occupation of Co(II) and Ni(II) ions in M1 octahedral sites compared to M2 octahedral sites. The preference of Mg(II) ions for M2 sites and the M1-O and M2-O distances jointly explain the pink color of the MgCoxNi1-xSiO4 solid solutions, while Co2SiO4 has a blue color. The presence of tetrahedral Co(II) ions leads to a change in color from pink to green or blue when these solid solutions are enamelled.

Summary: Material modification with low surface energy can achieve lower surface free energy on micro-and nano-rough structures, which is crucial for developing superhydrophobic surfaces. In this study, attapulgite (APT) was modified with alkylamine, alkylammonium salt, and stearic acid, and the interaction between low surface materials and attapulgite was explained. The results showed that the hydrophobicity of APT was significantly modified by the modifiers, and the surface free energy of the composites first decreased and then increased with increasing molecular number of low surface energy monomers.

Summary: The main aim of this study was to prepare a drug-drug coamorphous system to improve the physiochemical properties, solubility and stability of Apremilast and Indomethacin. Various solid-state characterization techniques were used to characterize the prepared system. Molecular level interactions were studied using molecular modeling and ATR-FTIR and 1H NMR. Solubility and dissolution studies showed the benefits of the coamorphous system. The system was found to be stable for a period of five months. Permeation study also demonstrated improved flux for both drugs compared to their crystalline forms. The coamorphous system showed anti-psoriatic and anti-melanogenic activity based on molecular docking results. Overall, the developed CAM-based supersaturated system exhibited improved physicochemical properties and physical stability.
