Current lithium ion battery technology will probably not be able to handle the coming decades' huge demand for energy. It is estimated that by 2050, electricity will make up 50% of the world's energy mix. Today that rate is 18%. But installed capacity for renewable energy production is expected to increase fourfold. This will require batteries that are more efficient, cheaper and environmentally friendly. One of the alternatives being studied today in many parts of the world is the lithium-air [...]

A computer-controlled technique inspired by evolutionary biology has been used to rearrangecarbon nanotubes suspended in liquid crystal through the application of electrical fields to cause them to act as a nanocircuit capable of performing simple computational tasks. Thescientists who conducted the experiment include Brazilian physicist Diogo Volpati. The experiment is described in the paper “Evolution of electronic circuits using carbon nanotube composites”, published [...]

Graphene is one of the most researched materials in the world today. The explanation is simple: consisting of a single layer of carbon atoms arranged in a two-dimensional honeycomb lattice of repeating hexagons, graphene is extremely thin, light and tough. In view of its other properties, such as transparency, flexibility, high electric and thermal conductivity, and low production cost, the number of potential applications is practically unlimited. Despite the vast amount of research conducted [...]
