Researcher have developed a novel graphene-based infrared (IR) detector demonstrating record high sensitivity for thermal detection. Graphene's unique attributes pave the way for high-performance IR ...

Infrared spectroscopy (IRS) is a technique used to analyze individual substances in isolation or a mixture, using their spectral information. IRS is based on the measurement of the wavelength and ...

Plasmon-enhanced molecular spectroscopies have attracted tremendous attention as powerful detection tools with ultrahigh sensitivity down to the single-molecule level. The optical response of ...

Researchers have long sought to develop multifunctional stealth materials capable of evading detection across different parts of the electromagnetic spectrum. However, achieving compatible stealth ...

The advanced Model IR400 Point IR Combustible Gas Detector from General Monitors features an industry-leading three-second T90 response time to the presence of combustible hydrocarbon-based gases, ...

Authorities in Virginia, US, have begun evaluating a new photonics-based sensor that it is hoped will reduce the incidence of drunk-driving. Launched by Governor Ralph Northam, the “Driven to Protect” ...

Most gases are extremely difficult to detect because they are odorless. Certain gases are extremely harmful to humans if inhaled. Owing to the above, researchers have developed many potent techniques ...

NASA's James Webb Space Telescope (JWST) utilizes mid-infrared spectroscopy to precisely analyze molecular components such as water vapor and sulfur dioxide in exoplanet atmospheres. The key to this ...
