4D Printing of Multimaterial Flexible Magneto‐Active Polymers

Advanced Materials Technologies, EarlyView.
Magneto‐active polymers are 3D‐printed with tunable mechanical and magnetic properties using both superparamagnetic and hard ferromagnetic fillers. Nano‐CT imaging reveals the spatial distribution of particles within the matrix. Programmable magnetization patterns and soft, flexible architectures enable responsive actuation, offering exciting ...

#AlleredenvomWetter #FridaysforFuture #FFF

, 2019
Die Umsetzung zu diesem Poster kam meiner Tochter, als sie sich mal wieder mit der Schulpflicht auseinandersetzen musste, die das Engagement für die Klimapolitik bremst. Besonders ärgert sie in diesem Zusammenhang, dass nur über die Schulpflicht, statt über mögliche Umweltschutz Sofortmaßnahmen diskutiert wird.

3D Printing of Stretchable, Compressible and Conductive Porous Polyurethane for Soft Robotics

Advanced Materials Technologies, EarlyView.
A 3D‐printable porous dopamine‐polyurethane acrylate elastomer results in conductive, stretchable, and compressible structures that can be metallized in situ through catechol‐mediated silver reduction. The resulting material function as both compliant soft robot with a and strain sensors without complex assemblies, enabling fully 3D‐printed soft ...

Bayesian inversion for the filtered flow at the Earth's Core Mantle Boundary

, 2013
The inverse problem which consists of determining the flow at the Earth's Core Mantle Boundary according to an outer core magnetic field and secular variation model, has been investigated through a Bayesian formalism. To circumvent the issue arising from
