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 [...]

Nuclear fusion, for the controlled and regular generation of electric power by converting hydrogen into helium and reproducing on a small scale what happens in our Sun (as well as other stars), is one of the foremost technological promises for the decades ahead. Designed to reach parameters beyond the ones previously obtained in laboratory experiments, the reactor prototype called ITER - "the way" in Latin - is presently under construction in southern France. Its design capacity is for 500 [...]

For over 65 years, niobium boride (NbB) has been considered a classic example of a superconducting material. This assumption, recorded in manuals on the physics of condensed matter and articles in scientific journals, has now been contested in a study conducted by researchers at the University of Sao Paulo (USP) in Brazil and at San Diego State University in the United States. In an article published in Physical Review Materials, the researchers show that the superconductivity detected [...]
