Angewandte Chemie, EarlyView.Compositionally engineered mixed solvated cocrystals enable modulation of thermosalient actuation. Guest ratio controls thermosalient temperature and propulsion intensity, providing a tunable platform for designing crystalline systems that exhibit stimuli‐responsive mechanical motion.

Electroactivity of PIPO nitroxide radical polymer films
Electrochimica Acta, 2021 ABSTRACT Nitroxide radical polymers (NRPs) are widely used as electroactive materials in a range of electrochemical applications, however, their preparation can be complex. Polyamine Immobilised Piperidinyl Oxyl (PIPO) is a commercially available, well-defined, NRP whose electrochemical properties have not been explored to date.

An Orally Administered Redox Nanoparticle That Accumulates in the Colonic Mucosa and Reduces Colitis in Mice [PDF]
, 2012 Background & AimsDrugs used to treat patients with ulcerative colitis are not always effective because of nonspecific distribution, metabolism in the gastrointestinal tract, and side effects. We designed a nitroxide radical-containing nanoparticle (RNPO)

SI‐bioATRP in Mesoporous Silica for Size‐Exclusion Driven Local Polymer Placement
Advanced Functional Materials, EarlyView.An enzyme‐catalyzed surface‐initiated atom transfer radical polymerization (SI‐bioATRP) of an anionic monomer within mesoporous silica particles, using hemoglobin as a catalyst, allows for controlling the location of the formed polymer via size‐exclusion effects between the nanopores and the biomacromolecules, thereby opening routes to functional ...

Ferronematics Based on Paramagnetic Nitroxide Radical Liquid Crystal
Crystals, 2015 We have prepared novel ferronematics based on a paramagnetic liquid crystalline (LC) material. Our ferronematics can disperse a higher volume fraction of magnetic nanoparticles compared to classical ferronematics because paramagnetic nature of the host ...
