Block copolymer synthesis by controlled/living radical polymerisation in heterogeneous systems [PDF]

open access: yes, 2016
Nanostructured soft materials open up new opportunities in material design and application, and block copolymer self-assembly is one particularly powerful phenomenon that can be exploited for their synthesis.

Engineered surface strategies to manage dental implant‐related infections

open access: yesPeriodontology 2000, EarlyView.
Abstract When exposed to the oral environment, dental implants, like natural surfaces, become substrates for microbial adhesion and accumulation, often leading to implant‐related infections—one of the main causes of implant failure. These failures impose significant costs on patients, clinicians, and healthcare systems.

From ab initio quantum mechanics to molecular neurobiology: A cation-pi binding site in the nicotinic receptor [PDF]

open access: yes, 1998
The nicotinic acetylcholine receptor is the prototype ligand-gated ion channel. A number of aromatic amino acids have been identified as contributing to the agonist binding site, suggesting that cation-pi interactions may be involved in binding the ...

Copper(0)-mediated radical polymerisation in a self-generating biphasic system [PDF]

open access: yes, 2013
Herein, we demonstrate the synthesis of well-defined poly(n-alkyl acrylate)s via copper(0)-mediated radical polymerisation in a self-generating biphasic system. During the polymerisation of n-butyl acrylate in DMSO, the polymer phase separates to yield a

PAMPS PolyHIPEs: The Role of Shape, Porosity, and Sulfonate Group Density on Metal‐Ion Adsorption From Water

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 9, March 5, 2026.
This study demonstrates how pore architecture, shape, and sulfonate group density influence the adsorption of Zn2+, Fe3+, and Al3+ by PAMPS polyHIPEs. Beads and monoliths exhibit distinct transport behavior compared to commercial 77H resin. The results offer design guidelines for optimizing ion‐exchange polymers to improve performance in water ...

Synthesis of novel glycopolymer brushes via a combination of RAFT-mediated polymerisation and ATRP

open access: yesSouth African Journal of Science, 2011
Glycopolymers (synthetic sugar-containing polymers) have become increasingly attractive to polymer chemists because of their role as biomimetic analogues and their potential for commercial applications.

Polymer brushes for antibiofouling and lubrication

open access: yesBiosurface and Biotribology, 2017
Surface-initiated atom transfer radical polymerization (SI-ATRP) could provide many merits for the preparation of polymer brush, such as the well-defined chemical configurations, gradient, architecture and thickness.

Synthesis of poly(methyl methacrylate)-poly(poly(ethylene glycol) methacrylate)-polyisobutylene ABCBA pentablock copolymers by combining quasiliving carbocationic and atom transfer radical polymerizations and characterization thereof [PDF]

open access: yes, 2015
Novel, unique amphiphilic pentab lock terpolymers consisting of the highly hydrophobic polyisobutylene (PIB) mid - segment attached to the hydrophilic combshaped poly(poly(ethylene glycol ) methacrylate ...

Nitroxide Mediated Polymerization of Styrene from Ladder‐Like Polysilsesquioxane: Synthesis and Characterization of Inorganic–Organic Hybrid Materials

open access: yesMacromolecular Chemistry and Physics, Volume 227, Issue 3, 16 February 2026.
LPSQ‐Macroalkoxyamines are used both as fillers and as initiators of styrene nitroxide‐mediated polymerization in the preparation of hybrid materials. The effects of this silicon‐based nanostructure on the thermal and viscoelastic properties of the final hybrid materials are presented.
