Dec 09, 2024 (Nanowerk News) It's easy to think that machine learning is a completely digital phenomenon, made possible by computers and algorithms that can mimic brain-like behaviors. But the first machines were analog and now, a small but growing body of research is showing that mechanical systems are capable...
Scientists and artists create enduring color-shifting coatings for architectural art
Dec 09, 2024 (Nanowerk Spotlight) Creating materials that change color based on viewing angle represents a significant challenge at the intersection of art and science. Natural examples of this phenomenon, called iridescence, appear in butterfly wings, peacock feathers, and opals. Unlike traditional pigments that absorb specific wavelengths of light, these...
New nano-device for generating structured light for advanced applications
Dec 09, 2024 (Nanowerk News) Researchers have developed a tiny, room-temperature device that creates a special type of structured light called radially polarized photons, which are highly useful for secure communication, advanced imaging, and precision optical tools. By carefully designing and positioning a quantum dot within a nanoantenna, they achieved...
