A recent conversation with Kevin Wilkinson, a professor of environmental chemistry at the Université de Montréal, sheds light on why no single signature can separate engineered nanoparticles from natural ones.

Happy World Oceans Day!
Although oceans cover over 70% of Earth's surface, they remain some of the least understood environments on the planet. In honor of World Oceans Day, this special digital booklet from Spectroscopy Magazine explores how cutting-edge technology is unlocking secrets from the seafloor to the surface. From using Raman spectroscopy to study microbial processes under extreme deep-sea pressure to deploying remotely operated vehicles that analyze hydrothermal vents in real-time, discover how analytical science is helping us appreciate both the beauty of the ocean and the critical role analytical science plays in understanding and protecting it.

This column shows that a Raman plate reader paired with partial least squares regression can simultaneously quantify glucose, fructose, sucrose, and ethanol in yeast fermentation samples, using turbidity-matched calibration standards to correct for yeast-induced turbidity, and offers a rapid, label-free, high-throughput method for tracking sugar consumption and ethanol production in strain screening, media optimization, and process development.
This column, the second installment on highly substituted benzene rings, shows that tri- and tetra-substituted substitution patterns can be distinguished by whether the ring bending peak is present and by the position of the in-phase aryl C-H wagging peak, which shifts according to how many adjacent hydrogens the ring carries.
How do ions and water interact at the atomic level in nanochannels grafted with polymer brushes using all-atom molecular dynamics simulations? Siddhartha Das of the University of Maryland and his team are working on answering this question.
Mammograms can find breast microcalcifications but can’t tell whether they are likely benign or malignant.
In a SciX interview, Marc Porter covered a lot of ground, from a student-driven pivot into immunoassays to a baseball analogy for Stokes and anti-Stokes scattering, and shares the open questions he is still chasing.
Laser-induced breakdown spectroscopy (LIBS) is being used in numerous application areas, including environmental monitoring, cultural heritage, and space exploration.
