A Gym for Cells—Direct Laser Writing of Magnetic Multilayered Micro Actuators for Mechanical Stimulation of Cells

open access: yesAdvanced Functional Materials, EarlyView.
Surface‐attached multilayer micromagnet systems are fabricated by two‐photon crosslinking. The pillar‐shaped micro actuators consist of a soft and flexible surface‐attached cell‐repellent hydrogel layer at the bottom, acting as a hinge and a cell‐adhesive hydrophobic polymer filled with magnetic nanoparticles.

Shape-variable four-petal Gaussian vortex breathers in strongly nonlocal nonlinear media

open access: yesResults in Physics, 2019
In this paper, we mainly investigate the propagation properties of shape-variable four-petal Gaussian vortex breathers in strongly nonlocal nonlinear media. The analytical expression of the shape-variable four-petal Gaussian vortex breather is derived in

Thin Film Mechanics

open access: yes, 2014
This doctoral thesis details the methods of determining mechanical properties of two classes of novel thin films suspended two-dimensional crystals and electron beam irradiated microfilms of polydimethylsiloxane (PDMS). Thin films are used in a variety of surface coatings to alter the opto-electronic properties or increase the wear or corrosion ...

Print‐and‐Plate Architected Electrodes for Electrochemical Transformations Under Flow

open access: yesAdvanced Functional Materials, EarlyView.
Typical flow cell electrodes are composed of stochastic porous carbon, limiting understanding of electrode structure‐performance relationships. This work describes an approach, termed “print‐and‐plate,” to prepare porous electrodes by direct ink writing followed by conformal metal coating.
