Structural damping using encapsulated Shear Thickening Fluids

Smart structures with tunable damping and stiffness characteristics are of high interest to aerospace applications, but often require an external power source to be activated. This can be avoided by using highly concentrated silica suspensions, which exhib ...

Link between Alginate Reaction Front Propagation and General Reaction Diffusion Theory

Jürgen Brugger, Philippe Renaud, Thomas Michael Braschler, Kristopher Pataky, Ana Valero, Ludovica Colella

We provide a common theoretical framework reuniting specific models for the Ca2+-alginate system and general reaction diffusion theory along with experimental validation on a microfluidic chip. As a starting point, we use a set of nonlinear, partial differ ...

Hydrogels for Urinary Tract Tissue Engineering

Lionel Ambroise Micol

Several urinary tract disorders, such as hypospadias or bladder cancer, require reconstructive surgery to preserve the patient's quality of life and at times even save their life. The current available surgical treatments, involving grafts from other tissu ...

In vivo study of an injectable poly(acrylonitrile)-based hydrogel paste as a bulking agent for the treatment of urinary incontinence

Peter Frey, Jeffrey Alan Hubbell, Lionel Ambroise Micol

Urinary incontinence can be treated by endoscopic injection of bulking agents, however, no optimal therapeutic effect has been achieved upon this treatment yet. In the present study, the development of a injectable poly(acrylonitrile) hydrogel paste is des ...

Alginate-Poly(ethylene glycol) Hybrid Microspheres with Adjustable Physical Properties

Jutta Christine Wandrey, Redouan Mahou

A one-step extrusion process under physiological conditions yielded calcium alginate-poly-(ethylene glycol) hybrid microspheres (Alg-PEG-M), for which the physical properties were adjustable by the macromolecular characteristics of the components, their co ...

Fluidic microstructuring of alginate hydrogels for the single cell niche

Jürgen Brugger, Philippe Renaud, Thomas Michael Braschler, Kristopher Pataky, Ana Valero, Ludovica Colella

Controlling alginate gel formation by diffusion of Ca2+ ions through a filter barrier, a layer-by-layer deposition technique with resolution on the size scale of a single cell is presented. It offers the possibility of exposing cells under biocompatible co ...

Hypoxia Impairs Skin Myofibroblast Differentiation and Function

Boris Hinz, Giorgio Pietramaggiori

Ischemic wounds are characterized by oxygen levels lower than that of healthy skin ( hypoxia) and poor healing. To better understand the pathophysiology of impaired wound healing, we investigated how switching from high ( 21%) to low ( 2%) oxygen levels di ...

Analyzing halftone dot blurring by extended spectral prediction models

Roger Hersch, Mathieu Hébert

Spectral prediction models for halftone prints generally assume homogeneously thick and sharply edged ink dots, i.e., bilevel halftones. In real prints, the ink thickness often decreases at the boundaries of the ink dots, thereby forming continuous-level h ...

Additive-Assisted Aqueous Synthesis of BaTiO3 Nanopowders

Paul Bowen

The effect of poly(acrylic acid) (PAA), poly(vinylpyrrolidone) (PVP), sodium dodecylsulfate (SDS), hydroxypropylmethylcellulose (HPMC), and D-fructose additives on the growth of BaTiO3 particles by aqueous synthesis is studied. Through different mechanisms ...

Integration column: Artificial ECM: expanding the cell biology toolbox in 3D

Matthias Lütolf

Many crucial cellular processes in our tissues are governed by complex, spatio-temporally regulated interactions between cells and their extracellular matrix (ECM). These interactions can be studied using well-established 3D in vitro model systems such as ...
