Researchers have developed a new way to see organs within a body by rendering overlying tissues transparent to visible light. The counterintuitive process—a topical application of food-safe dye—was reversible in tests with animal subjects, and may ultimately apply to a wide range of medical diagnostics, from locating injuries to monitoring digestive disorders to identifying cancers. […] The 2011 accident at the Fukushima-Daiichi plant in Japan inspired extensive research and analysis that elevated nuclear energy into a standard bearer for safety. It also inspired a number of studies at the U.S. Department of Energy’s (DOE) Argonne National Laboratory. Scientists want to look more closely at nuclear fuel materials to better understand how […] A team of physicists from The University of Hong Kong (HKU), Texas Tech University (TTH), and the University of Michigan (UMich), has made an important discovery in the study of van der Waals (vdW) magnetic materials, a special class of materials with unique electronic and magnetic properties that make them attractive for use in various […] As the global energy crisis intensifies and climate change accelerates, finding sustainable solutions for energy management is increasingly urgent. One promising approach is passive radiative cooling, a technology that allows objects to cool by emitting heat directly into space, requiring no additional energy. Go to Source How much do we really know about what else is out there in the universe? Go to Source Diamond is in many ways the ultimate material. Besides its enduring aesthetic value, diamond is also a highly versatile industrial material. While its claim as the hardest substance known to science has been usurped by ultra-rare minerals and newly developed synthetic materials, it still sits on the top of many rankings of material properties. Go […] Topological physics, which focuses on physical quantities that remain invariant under deformations, has garnered widespread interest in different areas of physics—photonics, quantum computing, solid-state physics, acoustics, and electronic circuits—due to its potential for noise-immune computation and signal processing. Go to Source As the “eyes of industry,” 3D measurement technology provides comprehensive, accurate, and reliable 3D information for high-end precision manufacturing. Optical measurement methods, such as structured light projection, have been widely adopted in various fields, including industrial inspection, intelligent assembly, advanced manufacturing, and material sorting. Go to Source The invention of optical frequency combs revolutionized frequency metrology and time-keeping. Miniaturization of such combs onto photonic chips, primarily leveraging the microresonator Kerr soliton frequency comb, expands on these functionalities by providing portable solutions to ultrafast spectroscopy, laser frequency synchronization, as well as stable optical, millimeter wave, and microwave frequency generation. Go to Source […] Near infrared (NIR) hyperspectral imaging is a highly promising detection technology capable of capturing detailed 3D spectral-spatial information, facilitating the identification and characterization of materials and targets based on their spectral signatures. Go to Source To build light-based quantum technologies, scientists and engineers need the ability to generate and manipulate photons as individuals or a few at a time. To build such quantum photonic logic gates that might be used in an optical quantum computer requires a special medium which allows strong and controlled interactions of just a few photons. […] Thousands of light particles can merge into a type of “super photon” under certain conditions. Researchers at the University of Bonn have now been able to use “tiny nano molds” to influence the design of this so-called Bose-Einstein condensate. This enables them to shape the speck of light into a simple lattice structure consisting of […] Healthy lighting technology is receiving increasingly widespread attention. Traditional solid-state lighting sources utilize photoluminescence down conversion technology to realize ideal white emission. Specifically, yellow phosphors are excited by blue LEDs, or three-primary-color phosphors are excited by ultraviolet LEDs. Go to Source In a collaboration between scientists from Physics and Chemistry at the University of Bayreuth and Physical Chemistry at the University of Melbourne, it has now been possible to realize optically switchable photonic units that enable precise addressing of individual units. This will make it possible to reliably store and read binary information optically. Go to […] A team led by Robert Keil and Tommaso Faleo from the Department of Experimental Physics has investigated the relationship between entanglement and interference in quantum systems of more than two particles in the laboratory.
