A window into the body: New technique makes skin invisible

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.

Nuclear fuel experiment demonstrates how liquid plutonium oxide behaves at the hottest temperatures

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 […]

Physicists capture first thickness-dependent transitions in two-dimensional magnetic material

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 […]

Novel metasurface enables temperature-adaptive radiative cooling

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.

Optoelectronic diamond device reveals an unexpected phenomenon reminiscent of lightning in slow motion

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.

A device to sort photon states could be useful for quantum optical computer circuits

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. […]

Creating an ‘imprint’ on a super photon

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 […]

Copper iodide nanoclusters offer environment-friendly solution for healthy lighting

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.
