Interlayer space tuning in MCM-22 type layered zeolites A first-principles analysis of pillaring in layered zeolitic MCM-22 type materials was carried alongside experimental characterization of pillared MCM-22 variants.
Earth-Abundant Metals Catalyze Energy-Efficient Carbon Dioxide Removal (CDR) Replacement of precious metals is achieved for chemical CDR with two earth-abundant metals working in tandem.
General Synthetic Strategy to Ordered Mesoporous Carbon Catalysts with Single-Atom Metal Sites for Electrochemical CO2 Reduction (CO2RR) Single-atom metals supported on ordered mesoporous carbons are promising catalysts for selective electrocatalytic reduction of CO2 to CO.
Lanthanum Catalyzes CH Borylation Inside Zeolite Micropores The zeolite-supported lanthanum borohydride, La(BH4)x-HY30, catalyzes C–H borylation of benzene with pinacolborane (HBpin) at 120 °C to give PhBpin. By capping the external silanol on zeolite particles, the single-site La catalyst was selectively grafted at Brønsted acid sites in micropores, increasing turnovers compared to La grafted on the unprotected support.
Methyl-Driver Overhauser Dynamic Nuclear Polarization A new dynamic nuclear polarization (DNP) mechanism has been discovered involving methyl rotation to mediate an Overhauser effect (OE).
Characterizing the Solvation Characteristics of Deep Eutectic Solvents Composed of Active Pharmaceutical Ingredients Solvation properties of active pharmaceutical ingredient-based deep eutectic solvents (API-DESs) were systematically studied. API-DESs were classified into different groups using their individual solvation interactions. Grouping of API-DESs can be used to interpret and explain their behavior in various chemical separations and material science.
Investigating the Solvation Interactions of Deep Eutectic Solvents Formed Using Choline Chloride and Polyalcohols Solvation characteristics of deep eutectic solvents (DESs) comprised of choline salts as the hydrogen bond acceptor (HBA) and polyols as hydrogen bond donor (HBD) were thoroughly characterized using gas chromatography.
Characterizing the Solvation Interactions of Choline Chloride-based Deep Eutectic Solvents Employed in Separations Solvation properties of choline chloride-based deep eutectic solvents (DESs) were thoroughly characterized using gas chromatography for the first time.
Using a Chromatographic Pseudophase Model to Elucidate the Mechanism of Olefin Separation by Silver(I) Ions in Ionic Liquids A three-phase chromatographic model treating silver(I) ions as a pseudophase is constructed and applied to investigate the olefin separation mechanism in silver(I) salt/ionic liquid (IL) mixtures. The partition coefficients and the values for enthalpy, entropy, and free energy of solvation of analytes are determined using the model.
3D Structures of Single Site Catalysts From the Ground Up A robust method for determining the 3D structures of arbitrary silica-supported molecules is developed.
