Synthesis and characterization of amphiphilic nitroxide 1,1,3,3–tetraethylisoindoline–2–oxyl–5–sodium sulfonate (TEIOSNa)

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The synthesis and characterization of an amphiphilic nitroxide to be used as a controlling agent in a nitroxide‐mediated living radical polymerization in aqueous dispersion media is presented. In the first stage of nitroxide synthesis (phthalimide protection), two reaction methods were employed: traditional and microwave.

Hsp90β‐Selective Inhibitors: Probing the Solvent‐Accessible Frontier

ChemMedChem, EarlyView.
The piperidinol ring of the KUNB106 scaffold (boxed in red) occupies the solvent‐exposed region of the Hsp90β ATP‐binding pocket, which provides a unique opportunity to optimize this region of the molecule. In the study disclosed herein, modifications such as CC bonds, heteroatoms, and three‐dimensionality result in improved inhibitors that further ...

Metamorphosis of Multilayered‐(NH4)2V7O16 Squares to Zinc Vanadate and w‐ZnO Nanoparticles via Zinc Metalation through Atomic Layer Deposition: Precision and Sustainability in Material Transformation

Chemistry–Methods, EarlyView.
Vapor phase metalation (VPM) enables Angstrom‐scale functionalization of (NH4)2V7O16 nanostructures using diethylzinc. This solvent‐free, gas‐phase method induces structural and magnetic transformations, aligning with circular economy goals. VPM enhances material properties for spintronics, neuromorphic computing, biomagnetism, and sustainable ...

Pigment‐Macromolecule Complexes Isolation from Sea Urchin Biomineral Waste for Coloring Materials

Chemistry–Methods, EarlyView.
A methodology has been developed to extract the colored organic fraction occluded within seashell biomineral waste. Applied to sea urchin skeletons, free polyhydroxylated naphthoquinone (PHNQ) pigments and PHNQ‐macromolecule complexes are isolated. These complexes show superior pH stability in purple hues compared to free PHNQ, which shifts from red to
