Catalytic ozonation of oxalic acid using carbon nanofibres on macrostructured supports

Carbon nanofibres (CNFs) were grown on different macrostructured supports such as cordierite monoliths, carbon felts and sintered metal fibres. The resulting composites exhibited excellent resistance to attrition/corrosion and its porosity is mainly due to ...

Osteoconductive surfaces generated from peptide functionalized poly(2-hydroxyethyl methacrylate-co-2-(methacryloyloxy)ethyl phosphate) brushes

Harm-Anton Klok, Dusko Paripovic

Modification of bone implant materials with biofunctional surfaces that facilitate osteoblast adhesion and promote matrix mineralization is an attractive strategy to improve osseointegration. This manuscript discusses the preparation and properties of RGD ...

Synthesis and post-polymerization modification of poly(pentafluorophenyl methacrylate) brushes

Harm-Anton Klok

Post-polymerization modification is a powerful strategy to endow polymers with functional groups that cannot be incorporated via direct polymerization. This manuscript explores the reversible addition-fragmentation chain transfer polymerization (RAFT) of p ...

Voltammetric Detection of Hg2+ Using Peptide-Functionalized Polymer Brushes

Harm-Anton Klok, Maarten Danial

Polymer brushes grafted by surface-initiated atom transfer radical polymerization (SI-ATRP) from the surface of Ir-based microelectrode arrays are explored as a platform for the fabrication of sensory coatings for the voltammetric detection of Hg2+. The po ...

Low-Stress Hyperbranched Polymer/Silica Nanostructures Produced by UV Curing, Sol/Gel Processing and Nanoimprint Lithography

Yves Leterrier, Valérie Geiser

Nanocomposite materials based on a HBP and silica are produced using either a dual-cure sol/gel and photopolymerization process or by mixing silica nanoparticles with the HBP. In both cases the conversion of the HBP is independent of composition and obeys ...

Screen-printed electrochemical chromium (VI) sensing electrodes for effluent bioremediation monitoring

Peter Ryser, Thomas Maeder, Caroline Jacq

In this work, we introduce a simple, low-cost and acid-resistant materials system for carbon-based screen-printed electrodes (SPEs), and apply it to chemical sensing of hexavalent chromium, i.e. Cr(VI), in acid environments, as encountered in bioremediatio ...

Polyimide foam-like microstructures: technology and mechanical properties

Philippe Renaud, Martinus Gijs, Sébastien Jiguet, Pierre Joris, Jagoda Anna Dobrzynska

We report a process for the realization of polyimide films with custom-designed microporosity based on the heat-induced depolymerization of polyimide-embedded polypropylene carbonate microstructures. The foam-like microstructures are up to 40 µm thick and ...

Exploring the Scope of the Baylis-Hillman Reaction for the Synthesis of Side-Chain Functional Polyesters

Harm-Anton Klok, Sanhao Ji

The BaylisHillman reaction provides a protective-group-free strategy to heterobifunctional polyesters, which can be further modified via various post-polymerization modification reactions. This contribution explores the BaylisHillman polymerization of 1,3- ...

Synthesis of Functional Polyesters via Baylis-Hillman Polymerization

Sanhao Ji

Aliphatic polyesters receive increasing attention over the last years driven by their application as biodegradable substitutes for conventional commodity thermoplastics and applications in the biomedical field, where amongst the family of biodegradable pol ...

A colorimetric CO sensor for fire detection

Nico de Rooij, Danick Briand, Kay Severin, Jérôme Courbat, Mirela Pascu

We report on a colorimetric carbon monoxide (CO) sensor based on a rhodium complex. The sensor relies on changes in the light absorption properties of the chemochromic reagent when exposed to the gas. Its optical properties in solution and in a polymeric m ...
