Researchers from the University of Illinois at Urbana-Champaign's Grainger College of Engineering have experimentally demonstrated a new way to transport energy even through wave-guides that are defective, and even if the disorder is a transient phenomenon in time.

Army researchers have discovered a way to monitor the performance of 3D printed parts, which tend to have imperfections that affect performance in ways traditionally-machined parts do not.

For the first time, monolayers of transition metal dichalcogenides with excellent optical properties were grown. A team of physicists from the University of Warsaw managed to overcome the technical difficulties faced by industry and scientists from around the world, namely the very limited size, heterogeneity, and broadening of the spectral lines of fabricated materials. Monolayers without these defects were grown by molecular beam epitaxy on atomically flat boron nitride substrates.

Diagnosis of Alzheimer's disease, the most common type of dementia, is not easy for its overlapping signs with normal ageing. A collaborative research by City University of Hong Kong (CityU) and Johns Hopkins University has developed a new non-invasive molecular imaging approach based on Magnetic Resonance Imaging (MRI) to dynamically measure glucose level changes in the brain lymphatic system. Their discovery may help in identifying Alzheimer's disease at early stages.

Hollow-core fiber technology developed in the Optoelectronics Research Centre at the Zepler Institute for Photonics and Nanoelectronics exhibits up to 1,000 times better polarization purity than state-of-the-art solid core fibers.

Memristive devices behave similarly to neurons in the brain. Researchers from the Jülich Aachen Research Alliance (JARA) and the technology group Heraeus have now discovered how to systematically control the functional behaviour of these elements. The smallest differences in material composition are found crucial: differences so small that until now experts had failed to notice them.

Over the past several years, a collaboration at HLRS has been developing a digital twin of Herrenberg, a small city just outside of Stuttgart, Germany. The Herrenberg study has already provided valuable information for city planners and government officials in the state of Baden-Württemberg, and paves the way for improving the model to include additional kinds of data.
