Sustainable, Reshapable Surfactant-Polyelectrolyte Plastics Employing Water as a Plasticizer

Paul Joseph Dyson, Zhaofu Fei, Antoine Philippe Van Muyden, Zhangjun Huang, Haiyan Jia

Natural polymers such as those present in foods contain abundant noncovalent intra- and intermolecular interactions, notably hydrogen bonds, which make them rigid when dry, but on exposure to water soften, due to disruption of these interactions. This soft ...

3D spacers enhance flow kinetics in resin transfer molding with woven fabrics

Véronique Michaud, Damiano Salvatori, Baris Çaglar

Impregnation time in Resin Transfer Molding (RTM) is directly proportional to resin viscosity and inversely proportional to fabric permeability, limiting the use of high-viscosity resins with conventional reinforcements. In this study, we show how to reduc ...

Polymer brush interfaces for protein biosensing prepared by surface-initiated controlled radical polymerization

Harm-Anton Klok, Mark Billing, Michael Badoux

Thin polymer films that are able to bind proteins are of great relevance for a wide variety of biosensor and biochip applications. Some of these applications require films that have high protein binding capacities while others call for surfaces that allow ...

Modeling Dielectric Constant Variability in Aggregate Polymers from CV Measurements

Marco Mattavelli, Jean-Michel Sallese, Catherine Dehollain, Diego Ruben Barrettino

Recently a new technique based on capacitive sensing has been developed and used to estimate the amount of moisture in polymers by means of the deviation of the dielectric constant. This technique is expected to be used for in-line monitoring of aggregate ...

Integration of sharp silicon nitride tips into high-speed SU8 cantilevers in a batch fabrication process

Georg Fantner, Nahid Hosseini, Jonathan David Adams, Oliver Peric, Santiago Harald Andany, Matthias Neuenschwander

Employing polymer cantilevers has shown to outperform using their silicon or silicon nitride analogues concerning the imaging speed of atomic force microscopy (AFM) in tapping mode (intermittent contact mode with amplitude modulation) by up to one order of ...

Hybrid laser 3D microprocessing in glass/polymer micromechanical sensor: towards chemical sensing applications

Yves Bellouard

We demonstrate the fabrication of a 3D polymer/glass micromechanical sensor by combining two femtosecond laser direct writing processes: subtractive laser-assisted chemical etching combined with additive two-photon polymerization techniques. In the first s ...
