Cyclen Tetra‐Amide Ligands as a Privileged Class of Ligands for Studying Second‐Sphere Coordination Environments

Chemistry – A European Journal, EarlyView.
Cyclen tetra‐amide derivatives provide a privileged ligand platform for controlling second‐coordination sphere structure. Hydrogen‐bond networks in the second‐coordination sphere are leveraged to stabilize a EuII‐containing cyclen tetra‐amide derivative in physiologically relevant conditions by limiting the access of O2, establishing a design‐principle

Photosensitizing Au(I) Catalysis With Coumarins

Chemistry – A European Journal, EarlyView.
A Au(I) complex with a tethered coumarin fragment was synthesized and characterized by UV‐vis and emission spectroscopy. Its ability to facilitate photo‐driven cross‐coupling reactions through single‐electron and energy transfer events was evaluated. ABSTRACT Gold catalysis shows versatility in a wide range of challenging transformations, wherein light‐

Synergistic Action of Ascorbic Acid and Readily Accessible NHC^N Ligands for the Oxidation of Gold(I) With Electron‐Rich Aryldiazonium Salts

Chemistry – A European Journal, EarlyView.
The synergic action of ascorbic acid and NHC^N ligands enables Au(I) oxidation with electron‐rich aryldiazonium salts. ABSTRACT The synergistic action of ascorbic acid and NHC^N ligands enables the challenging oxidation of Au(I) with electron‐rich aryldiazonium salts in the absence of a cocatalyst and/or irradiation. EPR, NMR, and x‐ray analyses reveal

Synthesis and characterization of a highly hydrophilic nanocomposite for wettability alteration, water/oil interfacial tension reduction, and enhanced oil recovery

The Canadian Journal of Chemical Engineering, EarlyView.
Mechanism of wettability alteration, interfacial tension reduction, and oil recovery by novel nanocomposite. Abstract The development of stable nanofluids (NFs) for enhanced oil recovery (EOR) relies on optimizing interactions between reservoir rocks and fluids.

3D printing of fluorine‐free omniphobic surfaces

Droplet, EarlyView.
Our work demonstrates that the simple and inexpensive digital light processing three‐dimensional printing can be used to fabricate micropillar arrays with doubly reentrant and triply reentrant features. The printed fluorine‐free surfaces display omniphobicity and resist the wetting of liquids with a wide range of surface tensions.
