Developing slurries for carbon capture: From synthetic gas mixtures to flue gas

AIChE Journal, EarlyView.
Abstract Deep eutectic solvent (DES)‐based systems have recently emerged as promising alternatives to conventional liquid sorbents for CO2 capture due to their tunable properties and potential for enhanced mass transfer. In this work, two DES‐based slurry systems previously developed for CO2 capture, one aqueous and one non‐aqueous, were further ...

Lanthanide Separation via Selective Precipitation Under Neutral Aqueous Conditions With a Functionalized EDTA Chelator

Angewandte Chemie, EarlyView.
An organic‐solvent‐free approach for efficient recovery of Nd from waste hard‐disk drive NdFeB magnets is achieved via selective precipitation with ethylenediaminetetraacetic acid (EDTA) substituted by hydrophobic cs‐124, under neutral conditions. Three precipitation cycles lead to 99.7% Nd puritywith 77% recovery yield; the chelator is simply recycled

How small changes to methylated piperidinium cations impact the synthesis of zeolite SSZ‐39

AIChE Journal, EarlyView.
Abstract Here we report a synthesis study of SSZ‐39 with four different organic structure directing agents (OSDA). The goal was to determine how subtle changes to the OSDA architecture impact crystallization kinetics, material composition, and other properties.

Accidents in the Chemical Industry: A Scoping Review Focused on Causal Factors

American Journal of Industrial Medicine, EarlyView.
ABSTRACT Background Although occupational safety in the chemical industry is an area of ongoing research worldwide, chemical incidents continue to occur, indicating the need to review the causes, assist in safety management, and identify problems in the quality of reporting. Methods A systematic search of studies published in English between January 1,

Histological analysis of the spatio‐temporal development of porcine knee cartilage in embryonic and early postnatal stages

Animal Models and Experimental Medicine, EarlyView.
This study dynamically charts the developmental process of the knee joint cartilage from the embryonic stage through to postnatal life, revealing key developmental events including the origin of knee joint development, chondrification, primary ossification, secondary ossification, formation of the cartilage cancal, and formation of the growth plate. It

Patient‐Personalized Membrane‐Coated Magnetic Nanovectors: Probing the Biomimetic Interface for Targeted Tumor Theranostics

Advanced NanoBiomed Research, EarlyView.
This study presents a label‐free spectroscopic platform to evaluate membrane protein conformation on patient‐derived glioblastoma cell membrane‐coated magnetic nanovectors. This work demonstrates that preserving membrane protein integrity during nanoparticle fabrication enhances homotypic tumor targeting and reduces hard protein corona formation ...

Complementary Eigen–Zundel Interpretation Reconciles Thermodynamics and Spectroscopy of Excess Protons in Aqueous HF Solutions

Angewandte Chemie International Edition, EarlyView.
Aqueous solutions of HF and HCl show contrasting dissociation in water, yet exhibit nearly identical excess‐proton spectra. This puzzling observation is reconciled by a complementary Eigen–Zundel interpretation. ABSTRACT Aqueous solutions of HF and HCl behave very differently at intermediate concentrations: HCl dissociates completely, whereas HFonly ...

Tuning Pore Geometry of Zirconium Metal–Organic Frameworks via Bent Ligands for Enhanced Sulfide Oxidation Catalysis

Angewandte Chemie International Edition, EarlyView.
Engineering pore geometry through ligand conformational bending enhances active‐site accessibility and mass transport in Zr‐MOFs, leading to superior catalytic sulfide oxidation. ABSTRACT Pore engineering represents a powerful strategy to tailor the physicochemical properties of metal–organic frameworks (MOFs), yet the structure‐activity relationship ...

Alkali‐Catalyzed Synthesis of Acylglycerol Estolides Exclusively from Castor Oil

Journal of the American Oil Chemists' Society, EarlyView.
This work advances sustainable chemistry by converting renewable castor oil into high‐performance estolides via solvent‐free, low‐energy catalysis. ABSTRACT Estolides are oligomers composed of fatty acid (FA) monomers linked through secondary ester bonds located along the mid‐chain region.
