Summary: The study demonstrated that birnessite effectively removes lincomycin from aqueous solution and the removal process follows a second-order model. The presence of cations inhibited the removal of lincomycin, while the addition of certain anions improved the efficiency of birnessite. Mn(IV) and Mn(III) were identified as core manganese species crucial for lincomycin removal. These findings shed light on the removal process of lincomycin and the impact of cations and anions on similar pollutant removal by birnessite.

Summary: This work presents a cost-effective and environmentally sustainable method for long-term storage of MXenes in aqueous solution by using hydration chemistry of nontoxic inorganic salts. By decreasing the water activity of saline solution, the attacking of MXene by free water and dissolved oxygen molecules can be inhibited, prolonging the storage life of MXene to up to 400 days at ambient conditions. Additionally, over 90% of the salt protectant can be recycled by simple evaporation of the final waste liquor after fully extracting the MXene, reducing waste discharge and processing cost.

Summary: This article investigates the effects of varying levels of calcium chloride and calcium sulfate on alkali-activated slag cementitious materials. The study analyzed the hydration products and mechanisms of the cementitious material using pH values, X-ray diffraction, thermogravimetric analysis, and scanning electron microscopy. The research findings suggest that calcium chloride is more effective in improving compressive strength than calcium sulfate when the dosage of Ca2+ is less than 2.5%. The addition of calcium chloride significantly enhances the compressive strength of the cement paste, especially at a 2% Ca2+ dosage and a Ca2+(CaCl2)-Ca2+(CaSO4) ratio of 1:1.

Summary: The reactivity of [B12X11](-) towards different nucleophiles varies depending on the substituent X, with temperature-dependent formation indicating an enthalpy order of (X=CN)>(X=Cl)≈(X=Br)>(X=I)≈(X=F). The binding of CO and N-2 to [B12X11](-) is significantly stronger compared to noble gases, and the B3LYP 0 K attachment enthalpies follow a different order. Experimental results and analyses support a rational understanding of the reactivity of [B12X11](-) and provide systematic data on pi-backdonation from delocalized sigma-electron systems of closo-borate anions.

Summary: This study reports the first discovery of stable bulk bassanite precipitated in solution, filling the gap in the calcium sulfate phase diagram. By precisely controlling water activity and using a polymer, bulk bassanite is formed instead of transforming into thermodynamically favorable gypsum. A new thermodynamic model of the non-classical crystallization process is proposed, and molecular dynamics simulation demonstrates the role of water molecules in initiating the assembly and growth of bassanite.

Summary: Research has shown that weakly hydrated anions can solubilize macromolecules but cause small molecules made from identical chemical constituents to precipitate out. This phenomenon can be explained by the regulation of anion binding to polymers by molecular curvature and interfacial water structure. The interactions of NaSCN with polyethylene oxide oligomers and polymers of varying molecular weight reveal a link between ion-specific effects and theories addressing how hydrophobic hydration is modulated by the size and shape of a hydrophobic entity.

Summary: This study demonstrates the sensitivity of the N-C-C-O open/close mode at 315 cm(-1) as a label-free probe for the local protonation of the amide group using precise terahertz measurements and molecular dynamics simulations. The approach is shown to be more general, as it can also be applied to other amino acids and allows for direct correlation of titration spectra with pK(a) values, showcasing the potential of terahertz spectroscopy for label-free probing of the charge state of natural amino acids in water.

Summary: In this study, the excitations of safranin and phenosafranin in an aqueous solution were analyzed using DFT/TD-DFT. It was found that the excitation energies of both dyes are the same, but there is a slight difference in emission energies due to different changes in atomic charges. The twisting of benzene rings relative to the chromophores does not occur upon excitation, and the hydration strengthens the H-bonds between the dyes and water, resulting in a bathochromic shift in the spectra.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.

Summary: In this work, two metal organic frameworks (MOFs) containing {Cu2I2} clusters, Eu-CuI-INA and Sr-K-CuI-INA, were synthesized and characterized. Both materials have a three-dimensional structure with {Cu2I2} clusters coordinated by INA(-) ligands and Eu3+ or Sr2+ ions. The Sr-K-CuI-INA material exhibited sensitive fluorescence sensing behaviors towards cysteine and nitro-bearing molecules, showing potential applications in bio and explosive molecule sensing. This work provides a good reference for designing fluorescent MOF probes containing CuI molecules.

Summary: Na-ion batteries (NIBs) have attracted great interest as a potential technology for grid-scale energy storage due to the wide distribution, low cost, and environmental friendliness of sodium resources. However, their implementation is hindered by low rate capability and cycling stability caused by the large ionic size of Na+. In this study, a three-dimensional nanoarchitectured coral-like CoSe2@N-doped carbon (CL-CoSe2@NC) was synthesized, and it exhibited improved sodium storage properties with better electrode kinetics and a stable SEI film.

Summary: Developing low-cost and self-supported bifunctional catalysts is crucial for highly efficient water splitting devices. In this study, nano-NiFe2O4 was directly grown onto iron foil surface and Sn4+ was introduced into the NiFe2O4. The resulting Sn-NiFe2O4/IF showed low overpotentials and high current densities during oxygen evolution reaction (OER) and hydrogen evolution reaction (HER), making it a promising catalyst for large-scale hydrogen production.
