17 de may. de 2024 · Learn about the definition, wavelengths, and applications of infrared radiation, the portion of the electromagnetic spectrum that extends from the red end of visible light to microwaves. Also, explore the photoelectric effect, the phenomenon of releasing electrons from a material when it absorbs light.
22 de may. de 2024 · A new, higher-resolution infrared camera outfitted with a variety of lightweight filters could probe sunlight reflected off Earth’s upper atmosphere and surface, improve forest fire warnings, and reveal the molecular composition of other planets.
21 de may. de 2024 · Infrared radiation is so named because the wavelength of infrared rays is just a bit longer than that of red rays. The only types of radiation that humans can detect are light rays. If humans could see infrared rays on the color spectrum, it would appear just after or below red.
31 de may. de 2024 · Integrating atomic force microscopy with time-domain two-dimensional infrared spectroscopy provides insights into molecular structures, mode coupling and energy transfers with high spatial...
Hace 16 horas · Herein, we developed a temperature-activated near-infrared-II fluorescence (NIR-II FL) and surface-enhanced Raman scattering (SERS) nanoprobe for long-term monitoring of temperature changes in rat arthritis and timely assessment of the status of osteoarthritis.
Hace 4 días · Electrochromic devices (ECDs), which are capable of modulating optical properties in the visible and long-wave infrared (LWIR) spectra under applied voltage, are of great significance for military camouflage. However, there are a few materials that can modulate dual frequency bands. In addition, the complex and specialized structural design of dual-band ECDs poses significant challenges. Here ...
Hace 3 días · Rocket Lab’s Electron rocket lifted off from Launch Complex 1 in Māhia, New Zealand at 11:15 p.m. NZST, June 5, 2024, carrying a small satellite for NASA’s PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) mission. The second of NASA’s PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) two satellites is ...
