In an international collaboration including EPFL, scientists have achieved giant nonlinearity of UV hybrid light-matter states up to room temperature in a waveguide made of AlInGaN, a wide bandgap semiconductor. The achievement paves the way for new devices in ultrafast chemical and biochemical spectroscopy.
Scientists from Nanyang Technological University, Singapore have developed a reusable nanotech mask that can block 99.9 per cent of bacteria, viruses and particulate matter, as well as kill bacteria in just 45 seconds.

X-rays are widely used to study the structures of various objects. New sources of x-rays, like Free Electron Lasers and 4th generation synchrotrons are being built around the Globe. The best optics for the new sources is usually made of the single crystal materials, such as silicon, germanium or diamond. However, the ideal periodicity of crystals leads to some unwanted diffraction losses - X-ray glitches. This effect causes dips in the intensity of the radiation transmitted through the optical element, down to zero. Scientists from the Immanuel Kant Baltic Federal University with foreign colleagues have developed a method that allows not only to predict the appearance of glitches but even to eliminate their influence on experiments.
In a major scientific leap, University of Queensland researchers have created a quantum microscope that can reveal biological structures that would otherwise be impossible to see.

MELVILLE, N.Y., June 9, 2021 Designing a soundscape to improve the quality of life for an individual is centered on putting their perception at the heart of the process. It becomes trickier for people who have diminished cognitive capacities.
During the 180th Meeting of the Acoustical Society of America, which will be held virtually June 8-10, Arezoo Talebzadeh, from Ghent University, will show how a personalized soundscape can help those with dementia by providing clues regarding time of day and place. The session, Soundscape design for people with dementia; the correlation between psychoacoustic parameter and human perception, will take place Wednesday, June 9, at 9:35 a.m. Eastern U.S.
