Ultrafast All-Polymer Electrically Tunable Silicone Lenses

Herbert Shea, Samuel Rosset, Luc Maffli, Michele Ghilardi

Dielectric elastomer actuators (DEA) are smart lightweight flexible materials integrating actuation, sensing, and structural functions. The field of DEAs has been progressing rapidly, with actuation strains of over 300% reported, and many application conce ...

Physically Based Modeling of Shear Modulus-Temperature Relationship for Thermosets

Thomas Keller, Anastasios Vassilopoulos, Wei Sun

A new physically based model for the simulation of the imaginary part of the shear modulus-temperature (G ''-T) curve of thermosets is introduced in this paper. The model is based on the modification of the G ''-T equation used for thermoplastic polymers v ...

Reversible supramolecular modification of surfaces

Negar Moridi

Enzymes are biocatalysts widely used in a large number of industrial biotech processes as they offer clear advantages over their chemical counterparts. Indeed, enzymes often show high substrate selectivity along with elevated turnover rates. Enzymatic cata ...

Self-Repairable, High Permittivity Dielectric Elastomers with Large Actuation Strains at Low Electric Fields

Yee Song Ko

A one-step process for the synthesis of elastomers with high permittivity, excellent mechanical properties and increased electromechanical sensitivity is presented. It starts from a high molecular weight polymethylvinylsiloxane, P1, whose vinyl groups serv ...

Improving hydrogels’ toughness by increasing the dissipative properties of their network

Dominique Pioletti, Mohamadreza Nassajian Moghadam

The weak mechanical performance and fragility of hydrogels limit their application as biomaterials for load bearing applications. The origin of this weakness has been explained by the low resistance to chains breakage composing the hydrogel and to the crac ...

Silaffins in Silica Biomineralization and Biomimetic Silica Precipitation

Carolin Christine Lechner

Biomineralization processes leading to complex solid structures of inorganic material in biological systems are constantly gaining attention in biotechnology and biomedical research. An outstanding example for biomineral morphogenesis is the formation of h ...

Characterization of the Network Structure of PEG Diacrylate Hydrogels Formed in the Presence of N-Vinyl Pyrrolidone

Jeffrey Alan Hubbell, Nicola Tirelli

PEGDA hydrogels copolymerized with NVP using free-radical photopolymerization are used in biomedical applications. These networks consist of a poly(acrylate-co-vinyl pyrrolidone) backbone crosslinked with PEG chains whose crosslink density is dependent on ...

Characterization of the mesh size of hydrogels from swelling properties

Mohamadreza Nassajian Moghadam

Hydrogels are cross-linked, water-swollen polymer networks that are widely used as a biomaterial. The suitability of hydrogels as biomedical materials, especially as drug delivery systems depend on their bulk structure. The most important parameters used t ...

Alginate-Poly(ethylene glycol) Hybrid Microspheres for Primary Cell Microencapsulation

Jutta Christine Wandrey, Redouan Mahou

The progress of medical therapies, which rely on the transplantation of microencapsulated living cells, depends on the quality of the encapsulating material. Such material has to be biocompatible, and the microencapsulation process must be simple and not h ...

Microscale patterning of hydrogel stiffness through light-triggered uncaging of thiols

Matthias Lütolf, Katarzyna Mosiewicz, Laura Kolb

Mammalian cell behavior is strongly influenced by physical and chemical cues originating from the extracellular matrix (ECM). In vivo, ECM signals are displayed in a spatiotemporally complex fashion, often composed as gradients and in concentration profile ...
