Quantum dots are nano-sized particles of semiconducting material, typically chalcogenides or phosphides of metals found across groups II to VI of the periodic table. Their small size causes them to exhibit unique optical and electrical properties which are now finding applications in electronics, optics and in the biological sciences. Synthesis of these materials began in the late 1980’s and this book gives a thorough background to the topic, referencing these early discoveries. Any rapidly-expanding field will contain vast amounts of publications, and this book presents a complete overview of the field, bringing together the most relevant and seminal aspects literature in an informed and succinct manner. The author has been an active participant in the field since its infancy in the mid 1990’s, and presents a unique handbook to the synthesis and application of this unique class of materials. Drawing on both his own experience and referencing the primary literature, Mark Green has prepared. Postgraduates and experienced researchers will benefit from the comprehensive nature of the book, as will manufacturers of quantum dots and those wishing to apply them.

The 'eleventh hour of the eleventh day of the eleventh month' of 1918 was supposed to be the conclusion of the 'war to end all wars'. Just twenty-one years after the armistice was signed, Barnsley, its borough and the world braced itself for a global conflict that history would eventually testify to be deadlier than the war that destroyed a generation of Barnsley men and boys. After the Great War, the famous market town stumbled into a new era that promised social change, including universal suffrage, economic and political stability and establishments of new international organisations such as the League of Nations to steer the masses. In reality, the town suffered in poverty, endured pit disasters, countless industrial deaths all the while still lamenting its lost generation, mercilessly butchered on The Somme. The books narrative explains in detail Barnsley's transition from its interwar years, to the euphoria of victory in 1945, supported by a timeline of national events that helped shape the town. It steers away from the common two-dimensional viewpoints some people had on the Home Front and the endless reusing of the same themes - 'the Great British spirit', Churchillian greatness, D-Day, Dunkirk and VE day. Although one cannot dismiss those remarkable qualities the town developed during the war, it also explores controversial topics such as social impacts, the rise in juvenile delinquency, misplaced optimism, increase in crime and the acceptance of the status quo by some members of the ruling council. Indeed, Barnsley rose to the challenge as it did years earlier, women once again revealed their rightful place in society as equals, miners smashed productivity records, men and women took up arms in anticipation of invasion. The Second World War had arguably the same impacts on Barnsley as the Great War, further local names etched on the memorials as a timeless reminder of the men, women and children who died or gave their life for their town, county and country. Never to be forgotten.

In recent years, considerable progress has been made in studying algebraic cycles using infinitesimal methods. These methods have usually been applied to Hodge-theoretic constructions such as the cycle class and the Abel-Jacobi map. Substantial advances have also occurred in the infinitesimal theory for subvarieties of a given smooth variety, centered around the normal bundle and the obstructions coming from the normal bundle's first cohomology group. Here, Mark Green and Phillip Griffiths set forth the initial stages of an infinitesimal theory for algebraic cycles. The book aims in part to understand the geometric basis and the limitations of Spencer Bloch's beautiful formula for the tangent space to Chow groups. Bloch's formula is motivated by algebraic K-theory and involves differentials over Q. The theory developed here is characterized by the appearance of arithmetic considerations even in the local infinitesimal theory of algebraic cycles. The map from the tangent space to the Hilbert scheme to the tangent space to algebraic cycles passes through a variant of an interesting construction in commutative algebra due to Angeniol and Lejeune-Jalabert. The link between the theory given here and Bloch's formula arises from an interpretation of the Cousin flasque resolution of differentials over Q as the tangent sequence to the Gersten resolution in algebraic K-theory. The case of 0-cycles on a surface is used for illustrative purposes to avoid undue technical complications.

Mumford-Tate groups are the fundamental symmetry groups of Hodge theory, a subject which rests at the center of contemporary complex algebraic geometry. This book is the first comprehensive exploration of Mumford-Tate groups and domains. Containing basic theory and a wealth of new views and results, it will become an essential resource for graduate students and researchers. Although Mumford-Tate groups can be defined for general structures, their theory and use to date has mainly been in the classical case of abelian varieties. While the book does examine this area, it focuses on the nonclassical case. The general theory turns out to be very rich, such as in the unexpected connections of finite dimensional and infinite dimensional representation theory of real, semisimple Lie groups. The authors give the complete classification of Hodge representations, a topic that should become a standard in the finite-dimensional representation theory of noncompact, real, semisimple Lie groups. They also indicate that in the future, a connection seems ready to be made between Lie groups that admit discrete series representations and the study of automorphic cohomology on quotients of Mumford-Tate domains by arithmetic groups. Bringing together complex geometry, representation theory, and arithmetic, this book opens up a fresh perspective on an important subject.
