This book cuts across the divisions of organic, inorganic, and physical chemistry. It describes new methods for creating -conjugated porphyrin oligomers with precisely defined sequences of zinc and copper metal cations, and how EPR spectroscopy was used to investigate the dipolar and exchange coupling between the paramagnetic copper(II) centres. Porphyrins are a group of heterocyclic macrocycle organic compounds that play an important role in our everyday life and can for example be found in blood where they form a red complex with iron (haem). Various metallic elements can be inserted into a porphyrin and changing the coordinated metal is an excellent way to influence the chemical and physical properties of these molecules. Focusing on 3 metals - zinc, magnesium and copper - the author established new methods for creating -conjugated porphyrin oligomers and lastly presents the synthesis and investigation of two novel porphyrin nanoballs. Giving the template-directed strategy the author developed for constructing these molecules, this work could provide access to other related nano-cages.

The book will primarily appeal to students of civil engineering and architecture, as well as to all practitioners in these areas who wish to broaden their fundamental understanding of topics in building physics.

This book elaborates on the acceleration of charged particles with ultrafast terahertz electromagnetic radiation. It paves the way for new, and improves many aspects of current, accelerator applications. These include providing shorter electron bunches for ultrafast time-resolved pump-probe spectroscopy, enabling complex longitudinal profiles to be imparted onto charged particle bunches and significantly improving the ability to synchronise an accelerator to an external laser. The author has developed new sources of terahertz radiation with attractive properties for accelerator-based applications. These include a radially biased large-area photoconductive antenna (PCA) that provided the largest longitudinally polarised terahertz electric field component ever measured from a PCA. This radially biased PCA was used in conjunction with an energy recovery linear accelerator for electron acceleration experiments at the Daresbury Laboratory. To achieve even higher longitudinally polarised terahertz electric field strengths, and to be able to temporally tune the terahertz radiation, the author investigated generation within non-linear optical crystals. He developed a novel generation scheme employing a matched pair of polarity inverted magnesium-oxide doped stoichiometric lithium niobate crystals, which made it possible to generate longitudinally polarised single-cycle terahertz radiation with an electric field amplitude an order of magnitude larger than existing sources.

'Einstein did not attempt to explain the constancy of the velocity of light: he assumed it and derived his theories accordingly. But we have explained it.' -- from Chapter 8 of Space and Counterspace Many people feel alienated by modern science and its impersonal view of our world, based on the concept of the 'detached observer'. Our human intuitions suggest that we need a broader-based science which can encompass phenomena currently excluded, such as human consciousness, qualities and values. In this groundbreaking book, Nick Thomas presents a wider view of science using the theory of 'counterspace'. Counterspace exists alongside space as we know it, and was first proposed by Rudolf Steiner, and developed by the Cambridge mathematician George Adams. Through its startling lens, key aspects of our world -- such as gravity, time, light and colour, as well as the stars, the solar system, and the classical elements -- can be viewed and understood in dynamically new ways. Thomas's work and ideas are on the cusp of a true revolution in the way modern scientific method can penetrate even deeper into the mysteries of our natural world.

This book describes computational methods used in quantum dynamics with emphasis on small quantum systems. Computational physics is a fundamental physical discipline at the forefront of physical research. Thus it is an indisputable fact that computational physics form part of the essential landscape of physical science and education. In the present state of scientific knowledge the importance of quantum dynamics is commonplace. Computational quantum dynamics involves the use of computer calculations and simulations to solve quantum physical problems. Following a brief introduction to quantum dynamics the book revisits approximation techniques based on perturbational theory and variationalmethods. This discussion includes Hartree-Fock and density functional theory and quantum Monte Carlo methods. The next chapter presents the concepts of finite differences. Central in this chapter is the discretization in time and space. Later chapters concentrate on discrete variable techniques based on orthogonal polynomials, finite element and B-splinemethods for both time-independent and time-dependent problems and the combination of different computational techniques. The final chapter contains a list of useful sources for computational software and program codes. This book is primarily aimed at advanced students and graduates and researchers in theoretical and computational physics or chemistry and bridges the gap between quantum textbooks and computational research. Although not essential, the reader should have a basic background in quantum physics and some knowledge of numerical analysis would be helpful in reading this book.

Standard approaches to understanding swarms rely on inspiration from biology and are generally covered by the term "biomimetics". This book focuses on a different, complementary inspiration, namely physics. The editors have introduced the term 'physicomimetics' to refer to physics-based swarm approaches, which offer two advantages. First, they capture the notion that "nature is lazy', meaning that physics-based systems always perform the minimal amount of work necessary, which is an especially important advantage in swarm robotics. Second, physics is the most predictive science, and can reduce complex systems to simple concepts and equations that codify emergent behavior and help us to design and understand swarms. The editors consolidated over a decade of work on swarm intelligence and swarm robotics, organizing the book into 19 chapters as follows. Part I introduces the concept of swarms and offers the reader a physics tutorial; Part II deals with applications of physicomimetics, in order of increased complexity; Part III examines the hardware requirements of the presented algorithms and demonstrates real robot implementations; Part IV demonstrates how the theory can be used to design swarms from first principles and provides a novel algorithm that handles changing environments; finally, Part V shows that physicomimetics can be used for function optimization, moving the reader from issues of swarm robotics to swarm intelligence. The text is supported with a downloadable package containing simulation code and videos of working robots. This book is suitable for talented high school and undergraduate students, as well as researchers and graduate students in the areas of artificial intelligence and robotics.

Fullerenes became a new member of carbon allotropes in addition to diamond and graphite after the discovery of C60 (carbon 60) by Kroto et al. in 1985. The model of C60 was first proposed by Osawa in 1970. C60 is a hollow spherical molecule composed of 60 carbon atoms that contains 12 five-membered rings and 20 six-membered rings and has the same structure as a soccer ball. In 2001, C60 fullerene nanowhiskers (FNWs), which are single-crystal nanowhiskers solely composed of C60 molecules, were discovered in a colloidal solution of lead zirconate titanate (PZT) with added C60. This book focuses on the synthesis of FNWs, fullerene nanotubes, and fullerene nanosheets and describes the structural, mechanical, semiconducting, and thermal properties, as well as bio-related and solar applications of FNWs and related fullerene nanomaterials.
