Tailoring the performance of nanocellulose-based multilayer-barrier paperboard using biodegradable-thermoplastics, pigments, and plasticizers
In this work a multilayer barrier paperboard was produced in a roll-to-roll process by slot-die coating of nanocellulose (microfibrillated cellulose or carboxymethylated cellulose nanofibrils) followed by extrusion coating of biodegradable thermoplastics ( ...
SPRINGER2023Active microrheology in corrugated channels: Comparison of thermal and colloidal baths
Hypothesis: The dynamics of colloidal suspension confined within porous materials strongly differs from that in the bulk. In particular, within porous materials, the presence of boundaries with complex shapes entangles the longitudinal and transverse degre ...
ACADEMIC PRESS INC ELSEVIER SCIENCE2022Control and Characterization of the Compactness of Single-Chain Nanoparticles
Francesco Stellacci, Luciano Andres Abriata, Lixia Wei, Suiyang Liao
Polymers when self-cross-linked into single-chain nanoparticles bear some resemblance to folded proteins; yet proteins have clear energy landscapes that determine precisely folded structures, while single-chain polymer nanoparticles (SCNPs) have more undef ...
AMER CHEMICAL SOC2021Strategies to Functionalize the Anionic Biopolymer Na-Alginate Without Restricting its Polyelectrolyte Properties
Sandrine Gerber, Jutta Christine Wandrey, Luca Szabó
The natural anionic polyelectrolyte alginate and its derivatives are of particular interest for pharmaceutical and biomedical applications. Most interesting for such applications are alginate hydrogels, which can be processed into various shapes, self-stan ...
2020'Green' Cr(III)-based electrodeposition of stainless steel-like FeCrNi: synthesis, mechanisms, material properties of films and micro-nanocomponents for bio-medical applications
The electrodeposition (ED) of stainless steel (SS) -like FeCrNi alloys for miniaturised devices is appealing for bio-medicine as it would allow combining excellent material properties (e.g. corrosion resistance, hardness, bio-compatibility) at low-cost.

EPFL2020How to polarise an interface with ions: the discrete Helmholtz model
Hubert Girault, Astrid Johana Olaya Avendano, Grégoire Clément Gschwend
The distribution of electrolytes in an electric field usually relies on theories based on the Poisson-Boltzmann formalism. These models predict that, in the case of a metallic electrode, ionic charges screen the electrode potential, leading to concentratio ...
ROYAL SOC CHEMISTRY2020Polymer Coatings to Minimize Protein Adsorption in Solid-State Nanopores
Aleksandra Radenovic, Sanjin Marion, Sebastian James Davis, Michael Mayer
Nanopore-based resistive-pulse recordings represent a promising approach for single-molecule biophysics with applications ranging from rapid DNA and RNA sequencing to "fingerprinting" proteins. Based on advances in fabrication methods, solid-state nanopore ...
WILEY-V C H VERLAG GMBH2020Composite Double-Network Hydrogels To Improve Adhesion on Biological Surfaces
Dominique Pioletti, Pierre-Etienne Bourban, Christophe Moser, Peyman Karami, Andreas Schmocker, Azadeh Khoushabi, Céline Samira Wyss, Martin Broome
Despite the development of hydrogels with high mechanical properties, insufficient adhesion between these materials and biological surfaces significantly limits their use in the biomedical field. By controlling toughening processes, we designed a composite ...
