Download Bioinspired Superhydrophobic Nano- and Microstructured Surfaces for Drag Reduction and Optoelectronics Book in PDF, ePub and Kindle
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.

Download NMR micro-detectors tailored for multinuclear and electrochemistry lab-on-a-chip applications Book in PDF, ePub and Kindle
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.

Download Advanced Elastocaloric Cooling Devices Based on Shape Memory Alloy Films Book in PDF, ePub and Kindle
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.

Download In Situ Characterization and Modelling of Drying Dynamics for Scalable Printing of Hybrid Perovskite Photovoltaics Book in PDF, ePub and Kindle
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.

Download Bioinspired Superhydrophobic Surfaces Book in PDF, ePub and Kindle
Materials with superhydrophobic or related properties are one of the most studied subjects from a theoretical point of view and also for the large range of possible applications, for example, anticorrosion, antibacteria, optical devices, and sensors. The study of natural species with special wettability has shown us the importance of surface structures and the surface energy of the resulting surface properties. Various strategies can be used to reproduce superhydrophobic phenomena in the laboratory. General reviews on superhydrophobic properties already exist but, to our knowledge, do not focus on metallic and inorganic materials. Here, we focus especially on the strategies implemented for reaching superhydrophobic or related properties using metallic and inorganic materials. Indeed, these materials present unique properties, for example, thermal and mechanical resistance, chemical and ageing resistance, and optical (transparency, antireflection, photoluminescence) and electrical properties (conducting, semiconducting, insulating). This book will be useful for graduate students of materials chemistry and physics and for researchers in surface science, nanostructures, and bioinspired or biomimetic materials.
