Abstract: We investigated the correlation between the temperature coefficient of elasticity (TCE) and Fourier transform infrared (FT-IR) absorption spectra of SiO 2 for SAW devices. The measurement ...

The human eye lacks photoreceptors responsive to the infrared spectrum, and infrared light with a longer wavelength and lower energy cannot trigger visual signals. In patients with severe eye diseases ...

In 2024, General Stephen Whiting, the commander of U.S. Space Command opposed the sale of both the 3.1 to 3.45 GHz and the 7.0 to 8.0 GHz parts of the electromagnetic spectrum when he testified ...

06/01/2025 June 1, 2025. Chinese researchers have developed an infrared contact lens that makes night vision possible. Nanoparticles make the previously invisible light range visible to the human eye.

A scaffolded infrared (IR) assignment was designed to support novice learners in developing the ability to analyze spectra. Beginning with pentane (containing no functional groups), students are ...

In an attempt to contribute to a better characterization of FeII and FeIII oxalate complexes, an investigation of their vibrational (infrared and Raman) and 57Fe-Mössbauer spectra was performed. It is ...

In a combined experimental and first-principles density functional theory (DFT) study, benzene steam reforming (BSR) over MgAl2O4-supported Rh and Ir catalysts was investigated. Experimentally, it has ...

A clear pattern emerged as he moved from the violet to the red end of the prismatic spectrum. Green light produced more warming than blue; red produced more warming than green. Which made Herschel ...
