Researchers provide new insights about singlet oxygen and set the stage for better understanding of this highly reactive and challenging substance. Singlet oxygen is an electronically excited state of oxygen that is less stable than normal oxygen. Its high reactivity…
A combined synthesis, FT-IR and DFT study of 4,6-dimethyl-2-hydroxy pyrimidine reports close theory-experiment agreement, strong intramolecular charge transfer, and a computed hyperpolarizability exceeding that of urea. News Source: Bethany Barker. (October 28, 2026). DFT and FT-IR study reveals electronic and optical…
The present can tell you a lot about the past, but you need to know where to look. A new study appearing this month in Genome Research reveals that protein architectures – the three-dimensional structures of specific regions within proteins – provide…
More research will be necessary to understand in detail the impact of the 3D structure of DNA on the communication between the various elements of the genome, and on the regulation of gene expression. Further down the line, this could also…
Scientists have created the most detailed maps yet of how human DNA folds, loops, and shifts inside living cells -- revealing a hidden layer of genetic control. In a major step toward understanding how DNA structure shapes human biology, scientists at…
A new method pairs magnetic molecularly imprinted extraction with machine learning-assisted FTIR spectroscopy to quantify the illicit dye Sudan I in chili powder within 90 minutes. The authors position the platform as a practical route to high-throughput, lower-cost monitoring of illicit…
Replacing just one atom gives new powers to biocompatible fluorescent molecules, say researchers. The Rice University lab of chemist Han Xiao reports in the Journal of the American Chemical Society that it has developed a single-atom switch to turn fluorescent…

This application note demonstrates the use of Raman spectroscopy to analyze the structural properties of carbon materials. Researchers performed chemical imaging on mechanical pencil refills of varying hardness to map graphite and disorder-related carbon structures at the submicron level. The…
Organic molecules have produced an electronic behavior that researchers have struggled to engineer in molecular materials. Scientists assembled triptycene-based molecules into a rare two-dimensional lattice and detected quantum states confined to its edges. The finding could widen the options for…
Light and molecules: Raman, infrared and other spectroscopy methods, and ultrafast and attosecond lasers that watch reactions as they happen.
