Mass Spectrometry and Infrared Spectroscopy to Improve Non-Contact Screening Methods at Airports
A Researcher from Lomonosov Moscow State University has developed a convolutional neural network (CNN) model for Fourier transform infrared (FT-IR) spectra recognition. This AI-based system is capable of classifying 17 functional groups and 72 coupling oscillations with remarkable accuracy, providing a significant boost to material analysis in fields like organic chemistry, materials science, and biology.
Spectroscopy published stories highlighting the work of Jeanette Grasselli Brown, as well as the latest analysis on spectral interpretation, atomic spectroscopy, and more.
I have been writing this column for almost 10 years, and we have reached a watershed moment. We have covered what I call the beginning and intermediate topics. However, before we venture off into advanced topics, a review is in order. I will spend the next four columns summarizing what we have learned so far so that the advanced topics will make more sense.
Spectroscopy sat down with Jeanette Grasselli Brown to discuss her early life and how she got started working in chemistry.
Spectroscopy Emerging Leader in Molecular Spectroscopy award winner Dmitry Kurouski and his team recently explored the link between fatty acids and neurodegenerative diseases.
Two distinct baseline correction methods: frequency-domain polynomial fitting, and time-domain molecular free induction decay (m-FID) are compared to determine which approach is more effective in reducing baseline errors in infrared absorption spectra.
Spectroscopy published stories on Raman, infrared spectroscopy, UV-vis, and more. Here are the top reads from the week.
A recent study analyzed the mid-infrared (mid-IR) and visible near-infrared (VNIR) spectra of primitive Main Belt asteroids.
We explore the buckminsterfullerene molecule using spectroscopy for its physical properties.
A recent study examined the ultraviolet-visible (UV-vis) and infrared (IR) spectra of theabrownins in dark tea.

In a recent study out of China, Liyi Zhou and her fellow scientists created a nanoprodrug system to help treat liver cancer.
Here are the top five articles that the editors of Spectroscopy published this week.
In this article, tunable diode laser absorption spectroscopy (TDLAS) is used to measure ammonia leakage, where a new denoising method combining empirical mode decomposition with the Savitzky-Golay smoothing algorithm (EMD-SG) is proposed to improve the signal-to-noise ratio (SNR) of absorbance signals.
A group of scientists led by Zozan Guleken of the Gaziantep University of Science and Technology in Gaziantep, Turkey looked into the blood serum composition of childhood obesity (CO) tissues using Fourier transform infrared (FT-IR) spectroscopy.
Scientists in Poland recently tested how multidimensional discriminant analysis and reflectance spectroscopy can help identify species within fungi strains.
Here are the top five articles that the editors of Spectroscopy published this week.
Scientists from Ben-Gurion University of the Negev, the Afeka Tel-Aviv Academic College of Engineering, and the Shamoon College of Engineering recently created a system that combines Fourier transform infrared (FT-IR) spectroscopy with machine learning algorithms to identify bacteria that is resistant to antibiotics.
A recent study published in The Astrophysical Journal explored two new substructures of the inner Milky Way, Shakti and Shiva, unearthing more information into the formation of the galaxy.
NASA’s X-ray Imaging and Spectroscopy Mission (XRISM) uses spectroscopy to study the hottest regions of the universe.
In a study led by scientists from Northwest University in Xi’an, China, carbon quantum dots were tested on how well they can detect hypochlorite and aid in cellular imaging.
In a recent study, spectroscopy-based detection protocols were used to detect Covid-19.
We wrap up our discussion of the mid-infrared spectra of inorganic compounds by looking at the spectra of silicates, nitrates, and phosphates. We will see that silicates have complex surface chemistry, and that infrared spectroscopy can tell us something about this. We will note that, of the five families of inorganics examined, the wavenumber ranges for the polyatomic anion stretching peaks in several of these functional groups overlap. However, polyatomic anion bending vibration peaks can be used to distinguish the five types of inorganics studied.
A recent study from Jagiellonian University examined how spectroscopic techniques can aid in the detection of pancreatic cancer.
