Technological evolution and revolution are both driven by the discovery of new functionalities, new materials and the design of yet smaller, faster, and more energy-efficient components. Progress is being made at a breathtaking pace, stimulated by the rapidly growing demand for more powerful and readily available information technology. High-speed internet and data-streaming, home automation, tablets and smartphones are now "necessities" for our everyday lives. Consumer expectations for progressively more data storage and exchange appear to be insatiable. Oxide electronics is a promising and relatively new field that has the potential to trigger major advances in information technology. Oxide interfaces are particularly intriguing. Here, low local symmetry combined with an increased susceptibility to external fields leads to unusual physical properties distinct from those of the homogeneous bulk. In this context, ferroic domain walls have attracted recent attention as a completely new type of oxide interface. In addition to their functional properties, such walls are spatially mobile and can be created, moved, and erased on demand. This unique degree of flexibility enables domain walls to take an active role in future devices and hold a great potential as multifunctional 2D systems for nanoelectronics. With domain walls as reconfigurable electronic 2D components, a new generation of adaptive nano-technology and flexible circuitry becomes possible, that can be altered and upgraded throughout the lifetime of the device. Thus, what started out as fundamental research, at the limit of accessibility, is finally maturing into a promising concept for next-generation technology.

This book provides a state-of-the art overview of a highly interesting emerging research field in solid state physics/nanomaterials science,  topological structures in ferroic materials. Topological structures in ferroic materials have received strongly increasing attention in the last few years. Such structures include domain walls, skyrmions and vortices, which can form in ferroelectric, magnetic, ferroelastic or multiferroic materials. These topological structures can have completely different properties from the bulk material they form in. They also can be controlled by external fields (electrical, magnetic, strain) or currents, which makes them interesting from a fundamental research point of view as well as for potential novel nanomaterials applications.To provide a comprehensive overview, international leading researches in these fields contributed review-like chapters about their own work and the work of other researchers to provide a current view of this highly interesting topic.

Research Paper (undergraduate) from the year 2006 in the subject Engineering - Civil Engineering, grade: A, Heriot-Watt University Edinburgh (School of Build Environment), course: Sustainablilty in Civil Engineering, language: English, abstract: The term sustainability is deemed to be a model for sustainable development for the humanity. Especially the Agenda 21 is setting on sustainability for solutions of environmental problems in present and future cases. To counteract an advancing degradation of the situation of people on the globe the Agenda 21 was created at a worldwide environmental conference in Rio de Janero, Brazil in 1992. Many years of intensive spadework had to be done befor all the different countries agreed on it. But does everyone in the world has the same ideas of sustainability and what is sustainable development all about? This work will show the different aspects of sustainability especially for civil engineering as it is demonstrated in the literatur but also a personal view on the theme. After a definition of sustainability the models of sustainable development are demonstrated to have a base of knowledge. You will see that sustainability is measurable and that there are aims to be aspired for a single human beeing as well as the hole population of our planet. Sustainability in civil engineering includes many differnt aspects like energy systems and technologies, building service engineering or management of resources. A precise assessment of existing or new buildings must be done and this work will give some examples of executed buildings and developed techniques.

Essay from the year 2007 in the subject Engineering - Civil Engineering, grade: A, Heriot-Watt University Edinburgh (School of Build Environment), course: Business Management for the Build Environment Professionals, language: English, abstract: There are various definition of strategic management in the literature because of the complexity and different approaches to deal with strategies. To give a brief idea what strategic management is all about the following definition is given. "e;Strategic management is a process, directed by top management, to determine the fundamental aims or goals of the organisation, and ensure a range of decisions which will allow for the achievement of those aims or goals in the long-term, whilst providing for adaptive responses in the short-term"e;. (Cole, 1997) Companies in the photovoltaic (PV) sector need to pass through the process of strategic management as well as their competitors. They will reach their aims and forecast or react on changes in the market to ensure the survival or development of the firm. This process will be presented in this work.

Das essential beleuchtet die spezifischen Risiken der persönlichen Haftung für öffentliche Unternehmen. Die Autoren lassen ihre Erfahrungen aus der Errichtung und Prüfung von Compliance-Strukturen in Unternehmen der öffentlichen Hand einfließen. Die Entwicklung der Rechtsprechung in jüngerer Zeit hat gezeigt, dass die Risiken der persönlichen Haftung auch für Entscheider in Unternehmen der öffentlichen Hand ein relevantes Berufsrisiko darstellen. Dabei spielt die Organisationsform (öffentlich-rechtlich oder privatrechtlich) keine nennenswerte Rolle.
