ATRP Grafting from Gel Coated Microspheres

, 2004
Swellable microspheres prepared by the precipitation polymerisation of divinylbenzene-80 (DVB-80) and 2-hydroxyethyl methacrylate (HEMA), in a solvent mixture of methyl ethyl ketone (MEK) and heptane, were functionalised with 2bromopropionyl bromide ...

Cobalt‐Doped Diamond‐Like Carbon Coatings Combined With Functionalised Polymers for Enhanced Tribological Performance

Lubrication Science, Volume 38, Issue 4, Page 191-197, June 2026.
ABSTRACT In recent years, doped diamond‐like carbon (DLC) coatings combined with functionalised copolymers have gained attention as a lubrication concept. While silicon‐doped DLC has been widely studied, polymer‐assisted lubrication on other doped DLC systems remains less explored.

Modulation of Surface-Initiated ATRP by Confinement: Mechanism and Applications

Macromolecules, 2017
The mechanism of surface-initiated atom transfer polymerization (SI-ATRP) of methacrylates in confined volumes is systematically investigated by finely tuning the distance between a grafting surface and an inert plane by means of nanosized patterns and ...

Dual Knockout Models of the Spatially and Functionally Conserved rgra and rgrb Zebrafish Genes Reveal the Requirement of RGR for the Integrity of Cone‐Mediated Photopic Vision, the Photopic Visual Cycle and Bruch's Membrane Morphology

The FASEB Journal, Volume 40, Issue 10, 31 May 2026.
This study investigates the role of the vision gene RGR using novel dual knockout zebrafish models. The loss of rgra and rgrb results in zebrafish larvae having reduced visual function and altered retinoid profiles under light but not dark conditions. The OKR phenotype is enhanced under higher light intensities.

How are Radicals (Re)Generated in Photochemical ATRP?

, 2016
The polymerization mechanism of photochemically mediated Cu-based atom-transfer radical polymerization (ATRP) was investigated using both experimental and kinetic modeling techniques. There are several distinct pathways that can lead to photochemical (re)

Contribution of Photochemistry to Activator Regeneration in ATRP

, 2016
With the recent interest in photochemically mediated atom transfer radical polymerization (ATRP), an interesting question arises: how significant are the photochemical processes in ATRP reactions that are supposed to be chemically controlled, such as ...
