Le graphène est devenu un nanomatériau précieux et utile en raison de sa résistance à la traction exceptionnellement élevée, de sa conductivité électrique, de sa transparence et du fait qu'il est le matériau bidimensionnel le plus fin au monde. Le marché mondial du graphène s'élevait à 9 millions de dollars en 2012, la majeure partie de la demande provenant de la recherche et du développement dans les domaines des semi-conducteurs, de l'électronique, des batteries électriques et des composites.Le graphène conduit très efficacement la chaleur et l'électricité le long de...

Energy engineering or Energy Systems Engineering is a broad field of engineering dealing with energy efficiency, energy services, facility management, plant engineering, environmental compliance, sustainable energy and renewable energy technologies. Energy engineering is one of the most recent engineering disciplines to emerge. Energy engineering combines knowledge from the fields of physics, math, and chemistry with economic and environmental engineering practices. Energy engineers apply their skills to increase efficiency and further develop renew- able sources of energy. The main job of...

As a subcategory or field of digital signal processing, digital image processing has many advantages over analog image processing. It allows a much wider range of algorithms to be applied to the input data and can avoid problems such as the build-up of noise and distortion during processing. Since images are defined over two dimensions (perhaps more) digital image processing may be modeled in the form of multidimensional systems. The gene-ration and development of digital image processing are mainly affected by three factors: first, the development of computers; second, the development of...

Graphen ist zu einem wertvollen und nützlichen Nanomaterial geworden, da es eine außergewöhnlich hohe Zugfestigkeit, elektrische Leitfähigkeit und Transparenz aufweist und das dünnste zweidimensionale Material der Welt ist. Der Weltmarkt für Graphen belief sich 2012 auf 9 Millionen US-Dollar, wobei der Großteil der Nachfrage aus der Forschung und Entwicklung in den Bereichen Halbleiter, Elektronik, elektrische Batterien und Verbundwerkstoffe stammt.Graphen leitet Wärme und Strom sehr effizient entlang seiner Ebene. Das Material absorbiert stark Licht aller sichtbaren Wellenlängen,...

Graphene has become a valuable and useful nano-material due to its exceptionally high tensile strength, electrical conductivity, transparency, and being the thinnest two-dimensional material in the world. The global market for graphene was $9 million in 2012, with most of the demand from research and development in semiconductor, electronics, electric batteries, and composites.Graphene conducts heat and electricity very efficiently along its plane. The material strongly absorbs light of all visible wave-lengths, which accounts for the black color of graphite; yet a single graphene sheet is...
