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...

Neuro-linguistic programming (NLP) is a pseudo scientific approach to communication, personal development and psychotherapy, that first appeared in Richard Bandler and John Grinder's 1975 book. The Structure of Magic I. NLP claims that there is a connection between neurological processes (neuro-), language (linguistic) and acquired behavioral patterns (programming), and that these can be changed to achieve specific goals in life. According to Bandler and Grinder, NLP can treat problems such as phobias, depression, tic disorders, psychosomatic illnesses, near-sightedness, allergy, the common...

A mind map is a diagram used to visually organize information into a hierarchy, showing relationships among pieces of the whole. It is often created around a single concept, drawn as an image in the center of a blank page, to which associated representations of ideas such as images, words and parts of words are added. Major ideas are connected directly to the central concept, and other ideas branch out-from those major ideas.Mind Mapping software's are designed to represent the relationships between ideas and concepts graphically. These mind mapping tools are visual thinking program which...

Energy storage is a critical hub for the entire grid, augmenting resources from wind, solar and hydro, to nuclear and fossil fuels, to demand side resources and system efficiency assets. It can act as a generation, transmission or distribution asset - sometimes in a single asset.Ultimately, storage is an enabling technology. It can save consumers money, improve reliability and resilience, integrate generation sources, and help reduce environmental impacts.

In power engineering, the term 'hybrid' describes a combined power and energy storage system. Examples of power producers used in hybrid power are photovoltaics, wind turbines, and various types of engine-generators - e.g. diesel gen-sets. In this concern, hybrid power plants often contain a renewable energy component (such as PV) that is balanced via a second form of generation or storage such as a diesel genset, fuel cell or battery storage system. They can also provide other forms of power such as heat for some applications.

Même si l'énergie éolienne produit de l'électricité plutôt que des combustibles liquides et ne peut donc pas remplacer immédiatement le pétrole dans la plupart des applications (en particulier dans les transports), les craintes de pénurie de pétrole n'ont fait que renforcer l'urgence de développer l'énergie éolienne. Les précédentes crises pétrolières avaient déjà incité de nombreux utilisateurs industriels et de services publics à se tourner vers le charbon ou le gaz naturel. L'énergie éolienne a montré qu'elle pouvait remplacer le gaz naturel dans la production...
