Self-assembly of copper and cobalt complexes with hierarchical size and catalytic properties for hydroxylation of phenol

open access: yesNanoscale Research Letters, 2011
A feasible and effective self-assembly method to synthesize different scale coordination polymers in highly dilute solution (from nanocrystals to microcrystals and to bulk crystals) without any blocking agent has been described. The growth of crystalline

Mechanism of Isonitrilase, a Nonheme Iron Decarboxylase Involved in the Biosynthesis of the Isonitrile Group in Peptides: A Computational Study

open access: yesChemistry – A European Journal, EarlyView.
A combination of molecular dynamics and quantum mechanics calculations shows that substrate is tightly bound inside the enzyme structure that enables two successive catalytic cycles with dioxygen and α‐ketoglutarate with an initial desaturation followed by hydrogen abstraction and decarboxylation steps to form an isonitrile substituent.

Unbound Intrinsic Formation Clearance of 6β‐Hydroxycortisol Is a Useful Biomarker of CYP3A4 Activity during Pregnancy

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Pregnancy results in multiple physiological changes that impact drug disposition. For example, hepatic CYP3A activity and renal transporter‐mediated clearance increase in late pregnancy, but the time course of these changes across pregnancy is not known.

Multi‐Cation (High‐Entropy) Doping of Mesoporous Co3O4 Thin Films With Cr, Mn, Fe, Ni, Cu, and Ag: Assessment of the Oxygen Evolution Reaction Performance

open access: yesEcoEnergy, EarlyView.
Mesoporous Co3O4 thin films doped with Cr, Mn, Fe, Ni, Cu, Ag, and a multi‐cation combination were synthesized via sol‐gel dip‐coating. Structural, optical, and electrochemical analyses reveal Fe and Cu as the most effective dopants for enhancing OER activity, whereas multi‐cation doping shows no synergistic improvement.

Light‐Induced Structural Reorganization of Fe Centers Unlocks High Efficiency of Visible‐Light Photo‐Fenton Water Cleaning Catalyst

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Bimetallic Cu and Fe oxide species supported on porous silica with interparticle mesoporosity act as efficient photo‐Fenton‐like catalysts under visible light. Photogenerated electrons drive the Cu2+/Cu1+ redox cycle. Part of Cu1+ is responsible for the regeneration of the Fe3+/Fe2+ cycle at neutral pH. Light irradiation additionally induces structural
