From tilings to quasicrystal structures and from surfaces to the n-dimensional approach, this book gives a full, self-contained in-depth description of the crystallography of quasicrystals. It aims not only at conveying the concepts and a precise picture of the structures of quasicrystals, butit also enables the interested reader to enter the field of quasicrystal structure analysis. Going beyond metallic quasicrystals, it also describes the new, dynamically growing field of photonic quasicrystals. The readership will be graduate students and researchers in crystallography, solid-state physics, materials science, solid- state chemistry and applied mathematics.

This volume is a collection of articles from the Proceedings of the International School of Structural Biology and Magnetic Resonance 7th Course: Structure, Structure and Biophysics - New Technologies for Current Challenges in Biology and Beyond. This NATO Advance Study Institute (ASI) was held in Erice (Italy) at the Ettore Majorana Foundation and Centre for Scientific Culture on 22 June through 3 July 2005. The ASI brought together a diverse group of experts in the fields of structural biology, biophysics, and physics. Prominent lecturers, from seven different countries, and students from around the world participated in the NATO ASI organized by Professors Joseph Puglisi (Stanford University, California, USA) and Alexander Arseniev (Moscow, RU). Advances in nuclear magnetic resonance (NMR) spectroscopy and X-ray crystallography have allowed the thr- dimensional structures of many biological macromolecules and their complexes, including the ribosome and RNA polymerase to be solved. Fundamental principles of NMR spectroscopy and dynamics, X-ray crystallography, computation, and experimental dynamics were taught in the context of important biological applications. The ASI addressed the treatment and detection of bioterrorism agents, and focused on critical partner country priorities in biotechnology, materials, and drug discovery. The range of topics here represents the diversity of critical problems between structural biology, biochemistry, and biophysics, in which lies the fertile ground of drug development, biotechnology, and new materials. The individual articles represent the state of the art in each area and provide a guide to the original literature in this rapidly developing field.

Single-molecule techniques eliminate ensemble averaging, thus revealing transient or rare species in heterogeneous systems [1-3]. These approaches have been employed to probe myriad biological phenomena, including protein and RNA folding [4-6], enzyme kinetics [7, 8], and even protein biosynthesis [1, 9, 10]. In particular, immobilization-based fluorescence te- niques such as total internal reflection fluorescence microscopy (TIRF-M) have recently allowed for the observation of multiple events on the millis- onds to seconds timescale [11-13]. Single-molecule fluorescence methods are challenged by the instability of single fluorophores. The organic fluorophores commonly employed in single-molecule studies of biological systems display fast photobleaching, intensity fluctuations on the millisecond timescale (blinking), or both. These phenomena limit observation time and complicate the interpretation of fl- rescence fluctuations [14, 15]. Molecular oxygen (O) modulates dye stability. Triplet O efficiently 2 2 quenches dye triplet states responsible for blinking. This results in the for- tion of singlet oxygen [16-18]. Singlet O reacts efficiently with organic dyes, 2 amino acids, and nucleobases [19, 20]. Oxidized dyes are no longer fluor- cent; oxidative damage impairs the folding and function of biomolecules. In the presence of saturating dissolved O , blinking of fluorescent dyes is sup- 2 pressed, but oxidative damage to dyes and biomolecules is rapid. Enzymatic O -scavenging systems are commonly employed to ameliorate dye instability. 2 Small molecules are often employed to suppress blinking at low O levels.
