Light refraction accounts for the change of direction and speed that a wave undergoes when passing from one medium to another. Glasses and contact lenses, microscopes and telescopes, or something as commonplace as the fact that a pencil inserted into a glass of water appears bent when viewed from the outside, have their origin in the optical phenomenon of refraction.
Terahertz radiation has become an important diagnostic tool in the development of new technologies. However, the diffraction limit prevents terahertz radiation (λ ≈ 0.01–3 mm) from being focused to the nanometer length scale of modern devices. In response to this challenge, terahertz scanning probe microscopy techniques based on coupling terahertz radiation to subwavelength probes such as sharp tips have been developed.
Focusing of light into the nanoscale represents a landmark for the implementation of nanotechnology in optics and biochemistry. Based on the exotic propagation of light in highly anisotropic materials (where light propagates in the form of rays along specific directions), a research team led by the University of Oviedo has demonstrated the focusing of infrared light into extraordinarily small regions.
The collaboration agreement for the project, which is expanding year on year, was signed this morning. The 17 organizations signing up to the agreement on the 6th edition of Emakumeak Zientzian are a significant representative sample of the Basque Country’s science and technology network. This coming together is the result of an open-door initiative always aspiring to unite and convinced that we are better off by adding.
The quantum simulation method and program developed by Artacho and others, known by its acronym SIESTA, is open and free for the research community.
In the framework of this program, the Basque nanoscience research center will be receiving this summer at least ten new students in their 3rd and 4th years of Physics, Chemistry, Biology, and Engineering. For a period of two months, undergraduates will be collaborating with nanoGUNE researchers in their research projects in the areas of nanoscale optics, nanobioengineering, electronic phenomena and magnetism, and nanoscale materials.
The book sets out to explain to the general public how cutting-edge research is conducted in the field of nanoscience and nanotechnology. How does “the big challenge of the small” materialize on a day-to-day basis? How can a truly innovative, daring project come to fruition? The story, written in a lively style by the journalist Elixabete Garmendia, answers this question which can now be read in Basque, Spanish and English.
