Summary: Lithium silicate-based CO2 sorbents were synthesized using steel metallurgical slags, with K2CO3 addition improving CO2 capture efficiency by facilitating CO2 diffusion. The best capture capacity value of 104 mg(CO2)/g(material) was achieved with 20 wt% K2CO3 at 600 degrees C. Thermal stability was excellent, with only a 10% reduction in CO2 capture capacity after 20 adsorption-desorption cycles using 20 vol% CO2.

Summary: The present study investigates the influence of partial substitution of Mn by Pd on structure, thermomagnetic properties, and phase transitions in the MnCoGe alloys. The research reveals the existence of orthorhombic TiNiSi-type and hexagonal Ni2Ti-type phases. The increase in Pd content leads to changes in lattice parameters and phase quantity, as well as an increase in Curie temperature.

Summary: This paper investigates the electrical properties and physicochemical transformations of porcine bone through in-situ impedance spectroscopy and complementary techniques. The conduction behavior in biogenic hydroxyapatite is influenced by intergranular contact and crystal size. A thermal phase transition at around 973 K is detected, which involves changes in crystal size and out-diffusion of Mg to the surface. The correlation between structural and electrical properties is evident.

Summary: The industrial application of plywood made from soybean meal-based adhesive (SMA) was enhanced by improving the wet shear strength and water resistance through microwave-chemical treatment. The wet shear strength of SMA was improved to 0.93 MPa by optimizing microwave conditions and using PEG-PEI treatment, which was 32.86% higher than the China National Standard. The modified mechanism was characterized using various techniques, showing that the formation of crosslinking improved the bonding performance and water resistance of SMA, providing favorable conditions for further application.

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: In this study, we synthesized and self-assembled mPEG-block-PDL-block-PMMA triblock terpolymers using a metal-free catalytic system, which showed better polymerization control compared to sequential copolymerization. The blocks were found to be incompatible, leading to their self-assembly into multicompartment micelles in water.

Summary: Fluorinated boron species are important organoboron compounds used in bioanalysis and antifungal drugs. The presence of fluorine substituents increases the acidity of boronic compounds, which is crucial for their interactions with bioanalytes and pathogen enzymes. This review discusses the electron acceptor properties, NMR spectroscopy data, and solution equilibria of fluorinated boronic species, as well as the latest research on their biological activity.

Summary: The high triplet boracycle SO2B was successfully applied in TADF emitters PXZ-Dipp-SO2B and CZ-Dipp-SO2B, achieving near-complete separation of highest occupied and lowest unoccupied molecular orbitals and leading to low oscillator strength of the S-1 -> S-0 CT transition. OLEDs using CZ-Dipp-SO2B as the luminescent dopant displayed high external quantum efficiency and maximum luminance with low efficiency roll off. The rISC in CZ-Dipp-SO2B is mediated through vibronic coupling of two CT states, allowing stable OLED performance to be achieved in different host environments.

Summary: Stimuli-responsive copolymers were synthesized by post-polymerization quaternization of a poly(4-vinyl pyridine) (P4VP) block of a triblock terpolymer. Stable micelles were prepared using a self-assembly protocol, and their characterization was performed using light scattering and cryogenic transmission electron microscopy. The encapsulation and release of a model drug were studied using UV-Vis spectroscopy, showing selective response to specific geminal diols. This study presents a reproducible method for preparing stimuli-responsive systems with potential for targeted drug delivery, especially for cancer treatment.

Summary: A synthetic approach to two regioisomeric pi-electron extended [1,4]thiaborins annulated with two benzothiophene units has been developed. The obtained boracycles exhibit different electronic properties reflected in their aromatic characters, boron Lewis acidity, and UV-vis spectroscopic behavior. The spiro thiaborin-BODIPY complexes show excellent photocatalytic performance as singlet oxygen photosensitizers with high singlet oxygen quantum yields and full conversion of organic substrates.

Summary: Flexible and intrinsically safe single-ion gel polymer electrolytes with high transference number (0.75) were developed by blending poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) copolymer and biocompatible poly((sulfamate-carboxylate) iso-prene) (PISC) in carbonate solvents. A steady conductivity of 1.81 x 10-5 S/cm was observed for 15 days under normal air exposure conditions (RH = 45%-61%, T = 25-31 degrees C). The sodium metal battery with an NVP cathode showed 82% capacity retention after 45 cycles at 80 degrees C with a C/5 rate, and 67.92% capacity retention after 200 cycles at room temperature with a C/10 rate using the gel formed with a conventional liquid electrolyte even after air exposure.

Summary: A supramolecular behavior of a newly synthesized compound and a library of tetrazole-based H-bonding synthons were studied by X-ray crystallography and computational techniques. The supramolecular assembly was controlled by various interactions, including O...H, N...H, C...H, and pi-stacking interactions. The 3D topologies of the supramolecular architectures were visualized and dispersion forces played a crucial role. Quantum-chemical treatment revealed the chemical activity and stability of the compound. These findings provide valuable information for the design of therapeutic agents containing tetrazole motifs.

Summary: Hydrogelators form nanoscale networks when dissolved in water, resulting in hydrogels with unique properties that have applications in tissue engineering and drug delivery. The solubility of different derivatives of phenylboronic acid was measured, and m-isobutoxyphenylboronic acid (PBA) was identified as a low-molecular-weight hydrogelator based solely on phenylboronic acid. PBA hydrogels exhibited a combination of amorphous and crystalline phases and had their elastic modulus and viscoelastic properties tuned by adjusting the PBA concentration and adding urea. Additionally, PBA hydrogels demonstrated responsiveness to various triggers and selective absorption of dyes for liquid mixture separation, highlighting their potential in bioapplications as biodegradable, multistimuli-responsive hydrogelators.

Summary: In this study, new tavaborole derivatives were synthesized and their crystal structures were compared to investigate the effects of substitutions on the structure. The presence of a fluorine atom was found to reduce the molecular dipole moment and the hydrogen bond acceptor abilities of a ring oxygen atom, thereby affecting the structure of the main hydrogen-bonded motif.
