Nowadays, mostly everybody has heard about global warming, a problem that humanity faces and that can drastically change our climate in the upcoming years. This is caused by […]
In nature, light harvesting organisms make extensive use of energy and electron transfer between adjacent molecules. Thus, in the photosynthetic cell of an algae, bacterium, or plant, there are light-sensitive molecules called chromophores, which contain a π-conjugated system (a system […]
The German mineralogist Gustav Rose (1798 – 1873) made important contributions in the fields of petrology and crystallography. He was the first to use a reflective goniometer in Germany and developed a particular interest in the relationship between the crystalline […]
As the search for renewable energy sources has intensified, the discovery of efficient and cheap technologies for exploiting the energy from the sunlight has emerged as a key challenge.
Higher efficiency plays an increasingly important role in making competitive […]
Lithium-ion batteries are widely used in portable electronic devices and electric vehicles since their introduction by Sony in 1991. Safety is an important concern since about two billion cells are produced every year but with a one-in-200,000 failure rate. Excessive […]
Sunlight is the most important energy source of Earth. All earthlings live thanks to the ability of plants and bacteria to transform solar energy into chemical one. As sunlight is a free, and practically unlimited, energy source it is easy […]
Approximately 90% of world’s electricity is generated in turbines moved by hot steam, which, unfortunately, operate only at 30 to 40 percent efficiency. This means that around two thirds of the total energy input is lost into the environment […]
The most widely used metaphors for nuclear fusion reactors are the recreation of the Sun on Earth and the controlled explosion of a hydrogen bomb. In both cases, the first thing that comes to mind is the need for high-performance […]
In this third and last part of the series (1, 2) about ITER we continue giving insights into the most outstanding aspects of the ITER machine design.
The ITER divertor is a part of the […]
In this second part of the series about ITER (see first here), we start giving a more detailed description of the ITER machine. Then, we address some important challenges that have been identified for each of its parts and […]
