In the Second Edition new processes are included, including the process of micro- and nanothermoforming to g...
In Situ Characterization and Modelling of Drying Dynamics for Scalable Printing of Hybrid Perovskite Photovoltaics
Hybrid perovskite photovoltaics could play a vital role in future’s renewable energy production. However, there are still severe challenges when scaling the technology. In this work, perovskite solution films drying in laminar and slot-jet air flows are investigated extensively by optical in situ characterization. The main results are a quantitative model of perovskite drying dynamics and a novel in situ imaging technique – yielding valuable predictions for large-scale perovskite fabrication.
Development of an Electrochemical Biosensor Platform and a Suitable Low-Impedance Surface Modification Strategy
In this work, a flexible biosensor platform based on impedance spectroscopy and comprising of gold electrodes, polymeric flow cells and a suitable surface modification were developed. Initially, several surface modification techniques described in literature were implemented and optimized for impedimetric biosensors but their individual limitations rendered them unsuitable for this biosensor platform. A novel method based on photobleaching was developed and tested showing satisfactory results.
Innovative micro-NMR/MRI functionality utilizing flexible electronics and control systems
The advantages offered by the flexible electronics and control systems technologies were utilized for tackling the challenges facing two crucial Magnetic Resonance (MR) applications. The first application is in the field of interventional Magnetic Resonance Imaging (MRI), and the other application is in the field of Nuclear Magnetic Resonance spectroscopy (NMR).
Micro- and Nanostructured Microfluidic Devices for Localized Protein Immobilization and Other Biomedical Applications
A new immobilization method for the localized adsorption of proteins on thermoplastic surfaces is introduced. Artificial three-phase interfaces were realized by surface structuring to control the wetting behavior which lead to a preferred adsorption in these modified areas. Additionally, different fabrication methods were analyzed to determine mass fabrication capabilities. These fabrication methods also allowed the production of fully structured microchannels to tune the fluids behavior within.
Fabrication and Analysis of Bio-Inspired Smart Surfaces
This work introduces novel techniques for the fabrication of bio-inspired hierarchical micro- and nanostructures. The enormous potential of these techniques is demonstrated by presenting a synthetic gecko-like adhesive matching the adhesion and self-cleaning of geckos very closely and a nanofur which is superhydrophobic, superoleophilic, underwater air-retaining, and even self-healing when surface treated.
Development of Microactuators Based on the Magnetic Shape Memory Effect
The giant magneto-strain effect in Ni-Mn-Ga alloys is particularly attractive for actuator applications. Two different approaches are being pursued to develop MSM microactuators. To observe large deflections of Ni-Mn-Ga microactuators, the material should be exhibiting low twinning stress and large magnetic anisotropy. In addition, design rules and boundary conditions for operating the Ni-Mn-Ga actuator material are having significant importance for evolution of performance characteristics.
X-ray optics made by X-ray lithography: Process optimization and quality control
Grating based X-ray phase contrast imaging sets out to overcome the limits of conventional X-ray imaging in the detection of subtle density differences and opens a way to characterize a sample's microstructure without the need for ultrahigh spatial resolution. The technique relies on grating structures with micrometric periods and extreme aspect ratio - their fabrication by X-ray lithography with optimal structure quality is the topic of this work.
Power Generation by Resonant Self-Actuation
Die Forschung im Bereich der Mikro-Energiegewinnungssysteme wurde durch den Bedarf an autarken, stabilen Energiequellen für vernetzte drahtlose Sensoren vorangetrieben. Abwärme, insbesondere bei Temperaturen unter 200 °C, stellt eine vielversprechende, aber mit den derzeitigen Umwandlungstechnologien schwer zu gewinnende Energiequelle dar. - Research into micro energy harvesting systems has been driven by the need for self-sustaining, stable power sources for interconnected wireless sensors. Waste heat, particularly at temperatures below 200 °C, presents a promising but challenging energy source to recover using current conversion technology.
Magnetoresistive and Thermoresistive Scanning Probe Microscopy with Applications in Micro- and Nanotechnology
This work presents approaches to extend limits of scanning probe microscopy techniques towards more versatile instruments using integrated sensor concepts. For structural surface analysis, magnetoresistive sensing is introduced and thermoresistive sensing is applied to study nanoscale phonon transport in chain-like molecules. Investigating with these techniques the properties of shape memory polymers, a fabrication method to design application-inspired micro- and nanostructures is introduced.
