Clean energy could be verging on a revolution. In recent years, mainstream solar companies have invested increasingly significant sums in commissioning new pilot production lines. The goal is to realize commercial-scale manufacturing of novel perovskite solar cells.
Evidence as small as flakes of paint can be fundamentally important in forensic investigations. Every paint chip has its origin. So, by analyzing a paint chip, a connection can be made back to its starting point, which can provide vital evidence for forensics. Color analysis by microspectrophotometry is a critical technique for paint chip examinations. These analytical devices examine light absorption or reflectance spectra to determine the complete UV-visible-NIR spectrum of the sample. Beyond the exact color of the chip, it can also provide insights into its chemical make-up, age, and other attributes. From this information, it can be ascertained where the paint chip has come from and if it is of evidentiary value.
Cosmic exploration holds a unique place in the human psyche. It routinely pushes the boundaries of our understanding, and also of our technical capabilities. Although astronomy is largely concerned with queries and observations on a vast scale, many key insights come from the smallest possible components. Often the intricate details of the universe's composition are hidden in the tiniest particles.
Ever wondered why a butterfly's wings shimmer with iridescent hues or a peacock's feathers display a dazzling array of colors? Unlike pigments, which absorb and reflect specific wavelengths of light, these vibrant tones arise from a fascinating phenomenon known as structural color. These colors are vivid, dynamic, and can display properties such as iridescence, changing appearance when viewed from different angles.
In art, verifying the authenticity of pieces during transactions is paramount. While functional, traditional electronic tags and labels are easily detected and counterfeited, presenting a need for a more covert and effective tagging method. Microspectrophotometry offers an innovative solution to this challenge by utilizing aluminum (Al) nanostructures resonating across ultraviolet (UV) to infrared (IR) spectra. These micro-tags are microscopic, camouflaged into their surroundings, and capable of containing multiple sets of information, making them an ideal choice for discreet art tagging.
