Advanced Functional Materials, EarlyView.Dicarboxylate‐modified anionic hairy cellulose nanocrystals exhibit a high selectivity for dysprosium(III) over neodymium(III). This selectivity arises from disordered dicarboxylate cellulose “hairs” that enable cooperative ionic coordination, hydrogen bonding, and strain‐induced conformational shrinkage.

Synthesis of Azoles Condensed with, or Linked to, Nitroxides [PDF]
, 2015 Nitroxides connected to indoles, tetrazoles, or 1,3,4-oxadiazoles were synthesized by conventional and microwave-assisted cyclization reactions. New approaches to pyrrole-, pyrazole-, and triazoleannulated nitroxides are described.

Advanced Functional Materials, EarlyView.This article presents a photo‐responsive nanoparticle platform that precisely triggers copper‐dependent cuproptotic cell death in (drug‐resistant) cancer cells. The system remains stable and inactive in the dark but releases cytotoxic species upon red‐light irradiation, achieving potent activity in drug‐resistant breast cancer cells.

New Developments in Spin Labels for Pulsed Dipolar EPR [PDF]
, 2014 Spin labelling is a chemical technique that enables the integration of a molecule containing an unpaired electron into another framework for study. Given the need to understand the structure, dynamics, and conformational changes of biomacromolecules ...

Nitroxide‐Mediated Photo‐Polymerization: A Swiss Army Knife for Microfluidic Design
Advanced Materials Technologies, EarlyView.This article illustrates the application of NMP2 to the rapid (less than 1 h) photostructuring and sealing of model structures intended for microfluidic applications. Remarkably, the careful design of resin composition allows completing these steps by simply spreading bare monomer (i.e., no added photoinitiator) on top of the bottom layer embedding ...

Facile syntheses of 3,4-disubstituted pyrroline nitroxides and their further synthetic applications [PDF]
, 2016 Lithiation of an alfa,beta-unsaturated pyrroline nitroxide ester with LTMP at the beta-carbon followed by treatment with electrophiles led to a new series of 3,4-disubstituted pyrroline nitroxides, which could be used as valuable paramagnetic building ...
