Synthesis of homo- and copolymer containing sulfonic acid via atom transfer radical polymerization

open access: yesDesigned Monomers and Polymers, 2022
Well-defined functional poly(p-phenyl styrenesulfonate) and poly(p-phenyl styrene-sulfonate-co-styrene) were successfully synthesized by the atom transfer radical polymerization (ATRP) using CuBr/bpy(PMDETA) catalyst and 1-phenylethyl bromide (1-PEBr) as

“One-pot” dispersion ATRP and alkyne-azide Huisgen’s 1,3-dipolar cycloaddition in supercritical carbon dioxide: towards the formation of functional microspheres [PDF]

open access: yes, 2010
Functional polymers were successfully prepared in scCO2 by combining alkyne-azide 1,3-dipolar Huisgen’s cycloaddition and dispersion ATRP in a “one pot” process using new perfluorinated polymeric amino-based ligands that had a dual role, i.e.

Abstracting Asynchronous Multi-Valued Networks: An Initial Investigation [PDF]

open access: yes, 2011
Multi-valued networks provide a simple yet expressive qualitative state based modelling approach for biological systems. In this paper we develop an abstraction theory for asynchronous multi-valued network models that allows the state space of a model to

Polymer brush collapse under shear flow

open access: yes, 2017
Shear responsive surfaces offer potential advances in a number of applications. Surface functionalisation using polymer brushes is one route to such properties, particularly in the case of entangled polymers.

Robust Artificial Polyenzyme for Recyclable Pickering Emulsion and Cascade Synthesis

open access: yesChemCatChem, EarlyView.
Artificial polyenzyme (ArPoly) forms amphiphilic proteinpolymer conjugates that stabilize Pickering emulsions with tunable interfacial properties for biocatalysis. These emulsions enable efficient and robust single‐step reactions, multi‐step biocatalytic cascades, and whole‐cell catalysis.
