Experimental methods in chemical engineering: Atomic absorption spectrometry—AAS

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 5, Page 2206-2224, May 2026.
Abstract Elements absorb electromagnetic radiation (light) of a specific wavelength in proportion to the number of atoms in its path. As the atoms absorb this light energy, electrons rise from the ground state to an excited state. In atomic absorption spectrometry (AAS), high temperatures produce clouds of atoms from the sample (atomization) and ...

Reliable Estimation of Wavenumbers for Calcite Peaks

open access: yesJournal of Raman Spectroscopy, Volume 57, Issue 5, Page 821-827, May 2026.
The wavenumbers of the calcite peaks were accurately estimated using a combination of a He–Ne laser and Ne emission lines. The values following the ± symbol represent the expanded uncertainties, corresponding to an approximate 95% confidence interval. ABSTRACT The Raman‐shift wavenumber ( ∆ν~), which is calculated as the difference between the absolute

Uranium, vanadium, and chromium in fish scales: A redox‐unrelated accumulation pathway in continental margin sediments

open access: yesLimnology and Oceanography, Volume 71, Issue 5, May 2026.
Abstract Enrichment patterns of the redox‐ and bio‐sensitive trace elements U, V, Cr, and Ni in margin sediments are essential for environmental reconstructions. However, their sedimentary accumulation pathways are not fully understood. While the accumulation of toxic trace elements like Cd, Hg, Pb, and Zn has been relatively well studied in fish ...

An integrated social and natural sciences case study for the reuse of organic wastes as soil amendments

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 3, Page 965-982, May 2026.
Reusing organic waste materials, such as animal manure, as soil amendments reduces water and fertiliser demand, contributing to achieving the Sustainable Development Goals. However, organic wastes may contain contaminants of emerging concern (CECs), posing potential ecosystem and human health risks. Despite the importance of this issue, there is a lack
