Cell motions driven by the intracellular cytoskeleton are deregulated in metastatic cancer cells. Microfabricated substrates, assays and systems allow for creating simple yet well controlled microenvironments that mimic complex soft tissues and are compatible with high-resolution live cell imaging and quantitative analyses of single cell behavior. These tools enable studying of the cytoskeletal organization, mechanical properties, and motility patterns of cancerous cells.

Surface modification of cathode materials with metal oxides in lithium-ion batteries can improve their durability at high potential. In this study MgO coating effects on LiCoO2 are revealed by means of in operando depth-resolved X-ray absorption spectroscopy. A solid-solution phase of magnesium with LiCoO2 is formed at the surface which serves as a pillar and stabilizes the layer structure in the delithiated states at high potentials.

A simple method for the on-chip fabrication of anisotropic proteinaceous nanobiointerfaces for patterned co-cultures is presented using laminar flow patterned crystalline bacterial surface layer (S-layer) proteins. To generate multi-functional surface properties, S-layer proteins with cell-adhesive (rSbsB) and –repellant (SbpA), as well as biomolecule-binding capabilities (rSbpA/ZZ) are re-assembled within microchannels for on-chip patterning of co-cultures of mobile with adherent cell types.
- UV-Assisted Low Temperature Oxide Dielectric Films for TFT Applications

Solution-based oxide gate dielectric layers are prepared from metal nitrates using UV-assisted annealing at 150 °C. The leakage current densities of ZrO2 and Al2O3 dielectrics are less than about 10-9 A/cm2 at 1 MV/cm and comparable to those formed by annealing at higher temperatures. High dielectric constants and the low leakage current behavior of the dielectric layers provide excellent ZnO TFT performance, with a field effect mobility of 1.37 cm2/V.s and an off-current density of 10-12 A/cm2. This low fabrication temperature process is compatible with future plastic electronics technology.
- Driving Spin and Charge in Quantum Wells by Surface Acoustic Waves

Article first published online: 26 AUG 2014 | DOI: 10.1002/admi.201400181
A detailed theoretical investigation of the spin and charge dynamics in a quantum well under surface acoustic waves is given. In particular, a simple and transparent form of the dynamics is found in a co-moving reference frame. The calculated spin relaxation and precession lengths are in very good agreement with recent experiments.
