Book Description
Inspired by superhydrophobic leaves of water plants, a flexible superhydrophobic self-cleaning, transparent thin polymeric nanofur film was fabricated through highly scalable hot embossing and hot pulling techniques. Nanofur can retain an air film underwater, whose stability against external stimuli such as high pressure and movement through fluids is investigated. Additionally, the optical properties of nanofur are investigated and exploited to enhance the efficiency of optoelectronic devices.

Book Description
This work offers three solutions tailored to specific applications to overcome NMR challenges in the micro-domain. As the first sub-topic of this work, different potential electrode designs, compatible with NMR technique, are suggested and experimentally evaluated. As the second focus point, this work tackles multinuclear detection challenges. In parallel, a low-cost, broadband insert is discussed to enhance the sensitivity of standard NMR coils when a small sample volume is available.

Book Description
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).

Book Description
This work deals with the process of photon upconversion in surface-anchored metal-organic frameworks. During the upconversion, two low-energy photons are absorbed and fused into a higher-energy photon, which is emitted. In this work, this process is analyzed in surface-bound metal-organic frameworks by spectroscopic methods. Furthermore, the application for increasing the efficiency of solar cells is discussed.

Book Description
Elastocaloric cooling is an emerging solid-state cooling technology with the potential to provide environmentally friendly, efficient cooling. The elastocaloric effect in superelastic shape memory alloy films is used to develop advanced cooling devices for small-scale applications. Cascaded and parallelized devices are developed to increase device temperature span and cooling capacity. The concepts are proven experimentally, a maximum temperature span of 27° C is achieved in a cascaded device.

Book Description
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.

Book Description
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.

Book Description
Through millions of years' natural selection, sharkskin has developed into a kind of drag-reducing surface. This book shows how to investigate, model, fabricate and apply sharkskin's unique surface properties, creating a flexible platform for surface and materials engineers and scientists to readily adopt or adapt for their own bio-inspired materials.Rather than inundate the reader with too many examples of materials inspired by nature, sharkskin has been chosen as the center-piece to illustrate accurate 3D digital modeling of surfaces, complete numerical simulation of micro flow field, different fabrication methods, and application to natural gas pipelining. This is a must-read for any researcher or engineer involved in bio-inspired surfaces and materials studies.
