This book will give a collective insight into the different roles that nanostructured materials play in Type III solar cells.
Packed with useful information, this is an essential resource for anyone thinking of setting up and running a community energy project. 'Community energy' is often seen as simply groups of people setting up wind turbines or hydroelectric schemes, yet there's actually a lot more going on in the range of activities that community energy groups are involved in, and the impact these have. Community Energy provides an overview of the role of community renewable energy projects in the UK, examining the history of community renewable projects and the different types of project that have been successful and unsuccessful. An engaging and informative guide, it covers an introduction to renewable energ...
The Handbook of Chalcogen Chemistry: New Perspectives in Sulfur, Selenium and Tellurium provides an overview of recent developments, particularly from the last decade, on the chemistry of the chalcogen group elements (S, Se and Te). While up to a few decades ago, chalcogen chemistry was mainly centred on sulphur, in recent years the research based on Se and Te has increased dramatically, and has created huge scope for the use of compounds based on this type of chemistry. The Handbook is organised into two parts, the first of which deals systematically with the chemistry of chalcogens in relation to other group elements in the periodic table. It also includes an overview of metal-chalcogenides and metal-polychalcogenides. The second part reflects the interdisciplinary nature of chalcogen chemistry and focuses on biological, materials and supramolecular aspects of the field. This Handbook gives a comprehensive overview on recent developments over the last decade and is ideal for researchers in the field.

In this work synthesis and properties of novel Pi-conjugated polymers containing diketopyrrolopyrrole (DPP) and benzodifuranone (BZDF) chromophores in the main chain, which are suitable as active materials in optoelectronic applications, are developed and investigated. The polymers were synthesized via metal-mediated or -catalyzed Suzuki, Stille, Sonogashira and Yamamoto cross-coupling polycondensation reactions or by using oxidative and anodic electropolymerization. The resulting polymers were characterized using gel permeation chromatography, NMR-, UV/vis-, and fluorescence spectroscopy, mass spectroscopy, and cyclic voltrammetry. The polymers exhibit low HOMO-LUMO band gaps and reversible oxidation and reduction processes, which suggests a strong donor-acceptor character. Electrochromic properties were found upon oxidation and reduction. Additionally, a series of cross-linked conjugated microporous polymers was synthesized. They exhibit high surface area and micropores in nanometer range. Furthermore, the influence via variation of electron donor and acceptor on the HOMO-LUMO band gaps of the conjugated polymers was studied.
Conjugated polymers are gaining a lot of interest due to their inherent functional properties and applications in plastic electronics. Their characteristic charge transporting and conducting properties produces features including coloration, photoluminescence, electroluminescence, photoconductivity, and electrochromism. In order to develop new functional polymers, researchers need the background information on the synthesis of the different polymer systems. Conjugated Polymers focuses on the practical preparation of conjugated polymers with each chapter discussing a particular type of conjugated polymer including a general explanation of the polymer, experimental details for synthesis and characterization. Edited by world leading experts in the field of conjugated polymer synthesis, the book serves as a convenient guide for advanced undergraduate level and above.
This thesis focuses on two areas - the development of miniature plastic lasers that can be powered by LEDs, and the application of these lasers as highly sensitive sensors for vapours of nitroaromatic explosives (e.g. TNT). Polymer lasers are extremely compact visible lasers; the research described in the thesis is groundbreaking, driving forward the technology and physical understanding to allow these lasers to be routinely pumped by a single high-power LED. A notable advance in the work is the demonstration of nanoimprinted polymer lasers, which exhibit the world's lowest pump threshold densities by two orders of magnitude. The thesis also advances the application of these compact, novel lasers as highly sensitive detectors of explosive vapours, demonstrating that rapid detection can be achieved when microporous polymers are used. This work also demonstrates a prototype CMOS-based microsystem sensor for explosive vapours, exploiting a new detection approach.
This series of conference on “Electroactive Polymers: Materials and Devices” broadly covers the emerging areas of electron conducting polymers, ion conducting polymers, ferro electric and ferro magnetic polymers, liquid crystalline polymers, biopolymers and bio-compatible composites, superconducting polymers/organic super conductors, nano-polymers and polymer-nano composites which have been well received by the scientific community working in these fields.
Crystallography is one of the most multidisciplinary sciences, with roots in fields as varied as mathematics, physics, chemistry, biology, materials science, computation and earth and planetary science. The structural knowledge gained from crystallography has been instrumental in acquiring new levels of understanding in numerous scientific areas. P
This essential resource consists of a series of critical reviews written by leading scientists, summarising the progress in the field of conjugated thiophene materials. It is an application-oriented book, giving a chemists’ point of view on the state-of-art and perspectives of the field. While presenting a comprehensive coverage of thiophene-based materials and related applications, the aim is to show how the rational molecular design of materials can bring a new breadth to known device applications or even aid the development of novel application concepts. The main topics covered include synthetic methodologies to thiophene-based materials (including the chemistry of thiophene, preparation of oligomers and polymerisation approaches) and the structure and physical properties of oligo- and polythiophenes (discussion of structural effects on electronic and optical properties). Part of the book is devoted to the optical and semiconducting properties of conjugated thiophene materials for electronics and photonics, and the role of thiophene-based materials in nanotechnology.
