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.

Robust β‐myrcene block copolymer elastomeric vitrimers

Polymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

The influence of spin-labeled fluorene compounds on the assembly and toxicity of the aβ peptide. [PDF]

PLoS ONE, 2012
The deposition and oligomerization of amyloid β (Aβ) peptide plays a key role in the pathogenesis of Alzheimer's disease (AD). Aβ peptide arises from cleavage of the membrane-associated domain of the amyloid precursor protein (APP) by β and γ secretases.

Nitroxide‐Mediated Polymerization Synthesis of Geminal Bisphosphonate‐Functionalized (Co)polymers and Their Affinity to Hydroxyapatite Surface

Journal of Polymer Science, EarlyView.
A novel styrenic monomer bearing gem‐bisphosphonate groups is synthesized in a single step. The nitroxide‐mediated (co)polymerization of this monomer proceeds in a well‐controlled manner, yielding bisphosphonate‐functionalized (co)polymers with low dispersity.

Redox nanoparticle therapeutics to cancer — increase in therapeutic effect of doxorubicin, suppressing its adverse effect [PDF]

, 2013
The ultimate goal of cancer chemotherapy is to achieve a cure without causing any adverse effects. We have developed a pH-sensitive redox nanoparticle (RNPN), which disintegrates under acidic conditions and exposes nitroxide radicals, leading to strongly

In Situ Self‐Nanostructuring Enables Fast‐Recharging of an Aqueous‐Processed Organic Small Molecule Cathode

Small, EarlyView.
Self‐nanostructuring of redox‐active organic small molecules through in situ electrochemical postcrosslinking enabled an aqueous‐processed, stable, fast‐rechargeable organic electrode even with a high active content ratio and mass loading. ABSTRACT Redox‐active organic materials (ROMs) for batteries are emerging as sustainable alternatives to inorganic

Effects of tempol on renal medullary tissue hypoxia in an ovine model of Gram‐negative septic acute kidney injury

Experimental Physiology, EarlyView.
Abstract Renal arterial infusion of tempol (RAT) at the onset of Gram‐negative sepsis can prevent sepsis‐induced medullary tissue hypoxia and acute kidney injury (AKI). However, it is not known whether treatment with tempol at a clinically relevant time point of sepsis is similarly effective. Thus, we examined whether tempol can reverse renal medullary
