A chromium complex as NIR-II emitter
Substances that emit light in the near infrared (NIR) range are needed for a wide variety of applications, from fibre-optic telecommunications to imaging techniques for biomedicine. A Swiss research team has now for the first time developed a chromium complex that emits light in the coveted ...
A NIR-II-emitting chromium complex
Many applications, from fiber-optic telecommunications to biomedical imaging processes require substances that emit light in the near-infrared range (NIR). A research team in Switzerland has now developed the first chromium complex that emits light in the coveted, longer wavelength NIR-II range. ...
Success in developing vanadium alloys strong at high temperatures
In the future fusion reactor, plasma is confined by using the magnetic field inside the doughnut-shaped vacuum vessel. The blanket is in a location where it almost touches the plasma, and as if to enfold the plasma the blanket is placed on the inner surface of the vacuum chamber. The blanket, by ...
Compounds with the apatite structure differ from most classes by the variety of their chemical compositions: to create such substances, most chemical elements of the Periodic System can be used, while the characteristics of the crystalline structure of apatite will be preserved. The resulting ...
Analyzing oxide films at atomic level
Corrosion is an age-old problem that is estimated to cost about $1 trillion a year, or about 5 percent of the U.S. gross domestic product. Corrosion of metals can be particularly bad, but fortunately they are normally protected from catastrophic damage by naturally forming, super-thin oxide ...
By doping alumina crystals with neodymium ions, engineers at the University of California San Diego have developed a new laser material that is capable of emitting ultra-short, high-power pulses--a combination that could potentially yield smaller, more powerful lasers with superior thermal shock ...
Molecular ruby for use in materials sciences or catalysis
Chemists at Johannes Gutenberg University Mainz (JGU) and at the Université de Montréal in Canada have developed a molecular system capable of very precise optical pressure measurements. The gemstone ruby served as the source of inspiration. However, the system developed by the team headed by ...
Physicists, chemists, and materials scientists have been probing the nature of layered magnetic materials for several decades, searching for clues to the properties of these materials that are more complex than they appear. Layered material resembles the structure of a book. From a distance, it ...
A Rutgers-led team of physicists has demonstrated a way to conduct electricity between transistors without energy loss, opening the door to low-power electronics and, potentially, quantum computing that would be far faster than today's computers. Their findings, which involved using a special mix ...
Hundreds of consumer products with illegal amounts of restricted chemicals
The project report shows a relatively high number of products on the European market containing chemicals that are restricted under REACH. Inspectors in 27 European countries checked 1 009 mixtures, 4 599 articles and 17 substances. Overall, out of 5 625 targeted product checks, 18 % did not ...
