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 ...

spl lambda/400 nm), near-IR (/spl lambda//spl sim/850 nm), and IR (/spl lambda//spl sim/1550 nm) spectrum. The material properties of thin ITO films were characterized. Using resonant-cavity-enhanced ...

This would be particularly useful in the mid-infrared region, where the vibrational spectrum is used to interpret the presence of chemical species. Dispersing the photons in this way lowers the ...

4. DISCUSSION. Since the samples extracts were alcoholic extracts, ethanol bands could be in all FTIR spectra. Characteristic ethanol bands would be at ~3687 cm-1, related to stretching vibration of O ...

We investigate the sensitivity of femtosecond Fourier transform two-dimensional infrared spectroscopy to protein secondary structure with a study of antiparallel β-sheets. The results show that 2D IR ...

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.

Attribution (BY): Credit must be given to the creator. A scaffolded infrared (IR) assignment was designed to support novice learners in developing the ability to analyze spectra. Beginning with ...

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 ...

Learn how to interpret ¹H and ¹³C NMR spectroscopy results with this beginner-friendly guide. Understand chemical shifts, splitting patterns, integration, and structural analysis techniques.

Only a tiny sliver of the Universe’s light can be seen by human eyes. But today we’re catching glimpses of the invisible Nearly the entire sky, as seen in infrared wavelengths and projected at ...

A project at the University of Science and Technology of China has developed a contact lens allowing wearers to perceive near-IR wavelengths and see better in the dark.Described in Cell, the contact ...
