The use of neural implants for stimulation and recording show excellent promise in restoring certain functions to the central nervous system; and neuroprostheses remain one of the most important tools of neuroscientists for the elucidation of the brain’s function. Ailments such as Parkinson’s disease, obesity, blindness, or epilepsy are being studied from this angle. Development of better electrodes for recording and stimulation is therefore critical to ensure continuing progress in this field. This book addresses one of the main clinical complications of the use of electrodes, namely the reaction of the neurological tissue in the immediate vicinity of implanted devices. The authors describe new techniques for the assessment of this phenomenon, as well as new microfabrication techniques that impede the inflammatory response of the brain that tends to limit the lifetime and reduce the effectiveness of these devices. The measurement protocols and improved fabrication protocols described will become standard tools in the future of neuroprostheses.

With the challenges our society faces concerning energy and the environment, it is particularly vital to develop a more rational use of our resources, both renewable and non-renewable. A sustainable use of the available resources is only possible if engineers can rely on coherent indicators, among which the exergy efficiency is bound to play a major role.

Photovoltaic technology has now developed to the extent that it is close to fulfilling the vision of a “solar-energy world,” as devices based on this technology are becoming efficient, low-cost and durable. This book provides a comprehensive treatment of thin-film silicon, the most prevalent PV material, in terms of its semiconductor nature, starting out with the physical properties, but concentrating on device applications.

Solidication is one of the oldest processes for producing complex shapes for applications ranging from art to industry, and it remains as one of the most important commercial processes for many materials. Since the 1980's, numerous fundamental developments in the understanding of solidication processes and microstructure formation have come from both analytical theories and the application of computational techniques using commonly available powerful computers.

In recent years, the transport simulation of large road networks has become far more rapid and detailed, and many exciting developments in this field have emerged. In this perspective, the authors describe the simulation of automobile, pedestrian and rail traffic, coupled to new applications, such as the embedding of traffic simulation into driving simulators, to give a more realistic environment of driver behavior surrounding the subject vehicle.
