This thesis builds on recent innovations in multi-phase emulsion droplet design to demonstrate that emulsion morphologies enable a useful variety of dynamic optical phenomena. Despite the highly dynamic nature of fluid morphologies and their utility for stimuli-responsive, dynamic optical materials and devices, fluid matter is underrepresented in optical technology. Using bi-phase emulsion droplets as refractive micro-optical components, this thesis realizes micro-scale fluid compound lenses with optical properties that vary in response to changes in chemical concentrations, structured illumination, and thermal gradients. Theoretical considerations of emulsions as optical components are used to explain a previously unrecognized total internal reflection-enabled light interference phenomenon in emulsion droplets that results in rich structural coloration. While this work is focused on the fundamental optics of emulsion droplets, it also facilitates the use of light-emitting emulsion morphologies as chemo-optical transducers for early-stage food-borne pathogen detection. This thesis beautifully demonstrates the virtue of fundamental interdisciplinary exploration of unconventional material systems at the interface of optics, chemistry, and materials science, and the benefits arising from translation of the acquired knowledge into specific application scenarios.

This book discusses key techniques of protection and fault ride-through in VSC-HVDC grids, including high-speed selective protection, DC fault current limitation, converter restarting, and DCCB reclosing strategies. It investigates how high-speed transient-variable-based protection can be used to improve grids' acting sensitivity, acting reliability, and ability to withstand high transition resistance compared with traditional protection. In addition, it discusses the applicability of the pilot protections, including the current differential protection and travelign-wave based protection, in the dc grid, as well as the improved methods. Furthermore, it proposes several DC FCL topologies, which are suitable for DC grids. Lastly, in the context of overhead line application conditions, it explores converter restarting and DCCB reclosing strategies, which not only identify the fault property, but also limit the secondary damage to the system, improving the system's operation security and reliability. As such, the book offers a comprehensive overview of original and advanced methods and techniques for the protection of VSC-HVDC grids.

The book continues with a discussion of atomic clusters and nanostructures, focusing primarily on boron and carbon, exploring, in detail, the one-, two-, and three-dimensional structures of boron and carbon, and describing their myriad potential applications in nanotechnology, from nanocoating and nanosensing to nanobatteries with high borophene capacity. The broad discussion of computational modelling as well as the specific applications to boron and carbon, make this book an essential reference resource for materials scientists in this field of research.
This book presents a range of low-dimensional superlattice thermoelectric materials based on physical vapor deposition (PVD) methods and explores various material types, thicknesses, and processing conditions. With the advances made in the performance of semiconductor thermoelectric materials and the efficiency of thermoelectric devices in recent years, thermoelectric power generation systems are likely to replace traditional mechanical heat engines, offering an environmentally friendlier alternative. The use of low-dimensional, nanostructured materials can significantly increase the density of states near the Fermi level and greatly improve the thermoelectric properties of materials. In addition, the book demonstrates that it is possible to influence thermoelectric performance, establish more accurate mathematical models through the regulation of relevant parameters, and ultimately improve the thermoelectric figure of merit (ZT).

The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.
Agriculture is considered as a backbone of developing nations as it caters the needs of the people, directly or indirectly. The global agriculture currently faces enormous challenges like land degradation and reduced soil fertility, shrinking of land, low production yield, water accessibility and a dearth of labor due to evacuation of individuals from farming. Besides, the global population increases at an exponential rate and it is predicted that the global population will be 9 billion by 2050 that in turn leads to food crisis in near future. Although, green revolution revolutionizes the agriculture sector by enhancing the yield but it was not considered as a sustainable approach. Exorbitant use of chemical fertilizers and pesticides to boost the crop yield is definitely not a convenient approach for agriculture sustainability in the light of the fact that these chemical fertilizers are considered as double-edged sword, which on one hand enhance the crop yield but at the same time possess deleterious effect on the soil microflora and thus declines its fertility. Besides, it cause irreversible damage to the soil texture and disrupts the equilibrium in the food chain across ecosystem, which might in turn lead to genetic mutations in future generations of consumers. Thus, the increased dependence on fabricated agricultural additives during and post green revolution has generated serious issues pertaining to sustainability, environmental impact and health hazards. Therefore, nano-biotechnology has emerged as a promising tool to tackle the above problems especially in the agriculture sector. Nano-agribusiness is an emerged field to enhance crop yield, rejuvenate soil health, provide precision farming and stimulate plant growth. Nano-biotechnology is an essential tool in modern agriculture and is considered as a primary economic driver in near future. It is evaluated that joining of cutting edge nanotechnology in agribusiness would push the worldwide monetary development to approximately US$ 3.4 trillion by 2020 which clearly indicates that how agri-nanobiotechnology plays a pivotal role in the agricultural sector, without any negative impact on the environment and other regulatory issues of biosafety. Agri-nanobiotechnology is an innovative green technology, which provides the solution to global food security, sustainability and climate change. The current book is presenting the role of nano-biotechnology in modern agriculture and how it plays a pivotal role to boost the agri-business.

This book presents the mechanics of piezoelectric semiconductor structures where the main electromechanical coupling of interest is the interaction between mechanical fields and semiconduction. This volume stands as the first full book treatment of this multi-physical subject from the mechanics angle. The analysis of piezoelectric semiconductor structures and devices is an emerging and rapidly growing interdisciplinary area involving materials, electronics, and solid mechanics. It has direct applications in the new area of piezotronics and piezo-phototronics. The book is theoretical, beginning with a phenomenological framework and progressing to include solutions to problems fundamental to the theory and application. Dr. Yang illustrates how in piezoelectric semiconductors, mechanical fields interact with semiconduction through the piezoelectrically produced electric fields by mechanical loads. This provides the foundation of piezotronic and piezo-phototronic devices in which semiconduction is induced, affected, manipulated, or controlled by mechanical fields. Also discussing composite structures of piezoelectric dielectrics and nonpiezoelectric semiconductors as well as thermal effects, the book is an ideal basic reference on the topic for researchers. |
