To enable the development of wearable devices that possess advanced ultraviolet (UV) detection functions, scientists from Nanyang Technological University, Singapore (NTU Singapore) have created a new type of light sensor that is both flexible and highly sensitive. While invisible to the human ...
Free-electron laser FLASH coaxes superfluorescent emission from the noble gas xenon
Scientists have for the first time induced superfluorescence in the extreme ultraviolet range. Superfluorescence, or superradiance, could be used to build a laser that does not require an optical resonator. The team headed by DESY’s lead scientist Nina Rohringer used DESY’s free-electron laser ...
When molecules interact with the oscillating field of a laser, an instantaneous, time-dependent dipole is induced. This very general effect underlies diverse physical phenomena such as optical tweezers, for which Arthur Ashkin received the Nobel Prize in Physics in 2018, as well as the spatial ...
A solution for efficiency problem of artificial photosynthesis
Hydrogen-powered electronics, travel, and more may be a step closer thanks to the work of a collaborative team of scientists in Japan. The researchers have developed a new method to more efficiently produce a key component needed to convert solar energy and water into hydrogen fuel, a process ...
Organic photovoltaics with new properties
Organic solar cells that can be painted or printed on surfaces are increasingly efficient, and now show promise for incorporation into applications like clothing that also require them to be flexible. The Rice University lab of chemical and biomolecular engineer Rafael Verduzco has developed ...
Artificial photosynthesis system that generates hydrogen fuel and electricity at the same time
In the quest for abundant, renewable alternatives to fossil fuels, scientists have sought to harvest the sun's energy through "water splitting," an artificial photosynthesis technique that uses sunlight to generate hydrogen fuel from water. But water-splitting devices have yet to live up to their ...
A chemist from RUDN was the first to use catalysts with ruthenium nanoparticles to obtain hydrogen under the influence of visible light and UV radiation. In the future, such catalysts may be used for large-scale production of hydrogen fuel under the influence of sunlight.Photochemical reactions ...
A new type of photocatalysts -- nanostructures from titanium dioxide
A RUDN chemist developed a new type of photocatalysts - nanostructures from titanium dioxide. Hollow nanocubes with ultra-thin walls act like nanoreactors and provide for 28 fold more effective organic reactions at room temperature under the influence of visible light. Traditional methods of ...
Scientists have found that sunscreen from bathers releases significant quantities of polluting TiO2 (titanium dioxide) into the sea. This has the potential to harm marine life. This work, which comes from research on beaches in the South of France, was presented at the Goldschmidt geochemistry ...
Studying the fleeting actions of electrons in organic materials will now be much easier, thanks to a new method for generating fast X-rays. The technique means advanced measurements of fast reactions will now be possible in physics labs around the world, without having to wait to use expensive ...
