American scientists have developed a method to study changes in the structure of polycrystalline films of transition metal disulfides under the action of electric current using transmission electron microscopy. For example, molybdenum disulfide, the authors found that the most important Read more
Researchers from Canada and America have learned to control the beam of light with another beam without crossing. They created a gel in which parallel beams interact with each other, changing the characteristics of the surrounding substance, and in future Read more
German scientists have proposed to use for sun protection sensitive to the ultraviolet dyes that change color depending on the time and intensity of exposure to sunlight. The dyes they put on the bracelets, tattoos, fabric patches, glasses and contact Read more
Brazilian and American scientists have invented a simple and fast way to find defects in two-dimensional materials. To do this, they combined the method of microscopy using second harmonic generation microscopy with a dark field. Prior to this, the main Read more
The use of volatile mice several wavelengths for a confident echolocation inspired scientists to the development of a new method of diagnostics the damages of pipelines, which based on the combination of two sensing techniques: using neutrons and gamma-radiation. The Read more
Chinese engineers figured out how to cool the electronics with the help of evaporation of the liquid. For this they have created a coating, which picks up moisture from the air, then vaporizing it by heating. First and foremost is Read more
