Navigating the Radical Oxo‐Functionalization of Alkenes Toward Ketones

European Journal of Organic Chemistry, EarlyView.
Straightforward access to complex ketones in a single synthetic step: This Review surveys the latest advances in three‐component alkene 1,2‐oxo‐functionalizations. The opportunities unlocked by the so‐called single‐electron (1e–) logic, including access to a broad pool of radical precursors and carbonyl oxygen atom sources, are highlighted.

Experimental Determination of the Equilibrium Conditions of Binary Gas Hydrates of Cyclopentane + Oxygen, Cyclopentane + Nitrogen, and Cyclopentane + Hydrogen [PDF]

Industrial & Engineering Chemistry Research, 2010
In this work, four-phase hydrate equilibrium data for each of the systems cyclopentane (CP) + water + hydrogen, CP + water + nitrogen, and CP + water + oxygen were measured and are reported in the temperature range of 281.3-303.1 K and the pressure range of 2.27-30.40 MPa. Measurements were made using an isochoric method.

Thiolate Salt Mediated Dynamic Silyl Ether Exchanges for Polymer Network Design and Deconstruction

Macromolecular Rapid Communications, EarlyView.
This work introduces thiolate salts as mediators for dynamic silyl ether exchange. This platform enables the synthesis of reprocessable covalent adaptable polymer networks (CANs) and allows for sterically controlled, and tunable deconstruction of silyl ether‐containing thermosets.

Construction of Cyclopentanes Consisting of Five Stereocenters via NHC-Catalyzed Cascade Reactions of Enals with Oxindole-Dienones

, 2023
Despite the widespread presence of the chiral cyclopentane motif, the asymmetric synthesis of cyclopentanes containing five stereocenters remains a formidable challenge.

Natural Glycosides in Neurodegenerative Diseases: Multi‐Target Mechanisms via the Gut–Brain Axis

Phytotherapy Research, EarlyView.
Core pathological features of NDs and the mediating role of the gut_brain axis. The dysregulation of gut microbiota and intestinal barrier leakage trigger systemic inflammation, exacerbating abnormal protein aggregation (such as Aβ and α‐synuclein), oxidative stress, and neuroinflammation in the brain.

Surface‐Functionalized Poly(2‐Oxazoline)‐Based Grids Produced by Two‐Photon Polymerization as 3D‐Structured Hydrogels Promoting Cell Adhesion

Small, EarlyView.
Sidechain‐functionalized poly(2‐oxazoline) cross‐linkers were utilized to print grids with varying mesh sizes by two‐photon polymerization (2PP grids). The amino‐functionalized hydrogels were subsequently used to covalently couple the RGD‐containing peptide sequence GCWRGDSP (RGD) to the amino groups in the side chains. In cell adhesion tests with L929

Delivering Sulfate to LNAPL Body for Enhanced Source Zone Depletion (ESZD)

Groundwater Monitoring &Remediation, EarlyView.
Abstract This field pilot study evaluates the feasibility of applying sulfate to a light non‐aqueous phase liquid (LNAPL) body for achieving enhanced source zone depletion (ESZD) at a refinery site. Two rounds of gypsum land application (GLA) delivered sulfate to an 8000 ft2 area encompassing LNAPL‐containing monitoring wells MW‐2 and MW‐3, while MW‐1 ...
