Biologists, physicists and engineers are working together to make ever-smaller devices capable of studying the properties of tiny biological particles. Using nano-electrodes, encapsulated in a device with dimensions of a few hundred millionths of a metre, it is now possible to manipulate and trap single nano-scale biological particles such as a virus. The precisely controlled electric fields generated within the device can be used to trap single particles in field-cages or separate different viruses from each other, for example. This book is an introduction to the science behind the new technology, and explains how the electric field interacts with the particles. It describes how these micro-systems are manufactured and how they are used to study the electrical properties of the particles.
The Welsh princes were one of the most important ruling elites in medieval western Europe. This volume examines their behaviour, influence and power in a period when the Welsh were struggling to maintain their independence and identity in the face of Anglo-Norman settlement. From the mid-eleventh century to the end of the thirteenth, Wales was profoundly transformed by conquest and foreign 'colonial' settlement. Massive changes took place in the political, economic, social and religious spheres and Welsh culture was significantly affected. Roger Turvey looks at this transformation, its impact on the Welsh princes and the part they themselves played in it. Turvey's survey of the various aspects of princely life, power and influence draws out the human qualities of these flesh and blood characters, and is written very much with the general reader in mind.
The success, growth, and virtually limitless applications of nanotechnology depend upon our ability to manipulate nanoscale objects, which in turn depends upon developing new insights into the interactions of electric fields, nanoparticles, and the molecules that surround them. In the first book to unite and directly address particle electrokinetics and nanotechnology, Nanoelectromechanics in Engineering and Biology provides a thorough grounding in the phenomena associated with nanoscale particle manipulation. The author delivers a wealth of application and background knowledge, from using electric fields for particle sorting in lab-on-a-chip devices to electrode fabrication, electric field ...

Essays exploring interrelated strands of material ecologies, past and present British politics, and the act of writing, through a rich variety of case studies.Much as the complexities of climate change and the Anthropocene have queried the limits and exclusions of literary representation, so, too, have the challenges recently presented by climate activism and intersectional environmentalism, animal rights, and even the power of material forms, such as oil, plastic, and heavy metals. Social and protest movements have revived the question of whether there can be such a thing as an activist ecocriticism: can such an approach only concern itself with consciousness, or might it politicise literar...
A collection of chapters, authored by leading experts in the field, on the use of micro and nano technologies for biomedical applications.
The Fifth International Conference on Micro Total Analysis Systems, also known as JlTAS 2001, will highlight the latest exciting events in the world ofminiaturized devices and systems for performing chemical and biochemical experimentation This conference has become mandatory for those of us working in this field as it is indeed helping to define our discipline. We are grateful to the people of the MESA Research Institute of the University of Twente, particularly Piet Bergveld and Albert van den Berg, for starting this meeting in 1994. Their original intention was for the JlTAS meeting to be a small informal workshop. This workshop flavor was sustained through the second meeting held in Base...
First published in 2001.The standard work on its subject, this resource includes every traceable British entertainment film from the inception of the "silent cinema" to the present day. Now, this new edition includes a wholly original second volume devoted to non-fiction and documentary film--an area in which the British film industry has particularly excelled. All entries throughout this third edition have been revised, and coverage has been extended through 1994.Together, these two volumes provide a unique, authoritative source of information for historians, archivists, librarians, and film scholars.
Electrochemistry has been undergoing significant transformations in the last few decades. It is now the province of academics interested only in measuring thermodynamic properties of solutions and of industrialists using electrolysis or manufacturing batteries, with a huge gap between them. It has become clear that these, apparently distinct subjects, alongside others, have a common ground and that they have grown towards each other, particularly as a result of research into the rates of electrochemical processes. Such evolution is due to a number of factors, and offers the possibility of carrying out reproducible, dynamic experiments under an ever-increasing variety of conditions with reliable and sensitive instrumentation. This has enabled many studies of a fundamental and applied nature, to be carried out.
