Children and adults love pattern. Fascination with Escher and with the Alhambra and other patterns lead to intrigue into making them, understanding them and inventing them. Now in Tarquin's long tradition of pattern books that link art and mathematics, comes a new title. Lattice Labyrinth Tessellations, an exciting, fertile, yet almost unexplored Flatland situated in the gulf between Art and Mathematics. The astonishing and elegant designs revealed in this very short and almost elementary book are simple to make and beautiful to contemplate, yet are unmentioned in the textbooks and unknown to designers and architects, following in the footsteps of the celebrated Dutch graphic designer Maurits Escher. This is a guided workbook that will show you how to construct an unbounded range of potentially intricate patterns like those on the front cover. Many of these designs - in fact an infinite number - can be constructed, step-by-step following straightforward rules.

Using new instrumentation and experimental techniques that allow scientists to observe chemical reactions and molecular properties at the nanoscale, the authors of Surface and Nanomolecular Catalysis reveal new insights into the surface chemistry of catalysts and the reaction mechanisms that actually occur at a molecular level during catalysis. While each chapter contains the necessary background and explanations to stand alone, the diverse collection of chapters shows how developments from various fields each contributed to our current understanding of nanomolecular catalysis as a whole. The book describes how the size and shape of materials at the nanoscale can change their chemical and physical properties and promote more efficient reactions with fewer by-products. First it highlights the preparation, characterization, and applications of heterogeneous and supported metal catalysts. Then it covers the engineering of catalytic processes, structure and reaction control, and texturological properties of catalytic systems. The authors explain how surface science can elucidate reaction mechanisms and discuss the growing role of high-throughput experimentation and combinatorial approaches in catalysis. From fundamental concepts to future directions, Surface and Nanomolecular Catalysis offers a well-rounded compilation of noteworthy developments which will continue to expand and transform our understanding of catalysis, particularly in the context of clean energy and environmental applications such as fuel cells.

Novel carbon allotropes, such as spherical fullerenes and nanotubes, have been added, in the last three decades, to the traditionally recognised diamond and graphite. Although fullerene C60 has been speculated about for a long time. A fullerene is, according to a classical definition, an all-carbon molecule consisting entirely of pentagons (exactly 12) and hexagons (n/2-10). Non-classical fullerene extensions to include rings of other sizes have been considered. Fullerenes are commonly synthesised by arc-discharge or laser ablation methods. Spherical fullerenes became nowadays parts of real chemistry: they can be functionalised or inserted in supramolecular assemblies.

These tiny structures could offer architectural designs for the cities of the future. The authors explore the foam-like carbon structures, which relate to ‘schwarzites’ and which are infinite periodic minimal surfaces of negative curvature. They show that the periodicity of close repeat units of such structures is evident not only in these formations but also in all of the carbon allotropes. The text provides literature and data on the field of nanostructure periodicity and the authors’ own results on nanostructure building and energy calculations.

This lavishly illustrated volume provides a strikingly visual approach to geometric shapes and transformations in 2- ,3- , and 4-dimensional space. Invoking Plato's polygons, Kepler's polyhedra, and Fuller's polytopes, the author presents, by means of hundreds of beautiful illustrations (100 of them in full color), many complex designs which may be found in nature or which may be produced by computer graphics programs. This self-contained work reveals how polygons, polyhedra, and polytopes are effective tools or hieroglyphs with which we may investigate and describe the macro, medio, and micro worlds or the multi-dimensional world without any telescope or microscope and without requiring guidance from others. Forewards by Buckminster Fuller and H. S. W. Coxeter.
