Monitoring Sulfuric Acid and Temperature Using Raman Spectroscopy and Multivariate Chemometrics

Multivariate regression models were optimized for the quantification of sulfuric acid (H2SO4) [0–8 M] and temperature (20 °C–80 °C) in the presence of ammonium sulfate ((NH4)2SO4 [0–0.6 M]) using Raman spectroscopy. Optical vibrational spectroscopy is a useful nondestructive technique for the in situ analysis of complex chemical systems notoriously difficult to monitor in…

Raman Spectroscopic Investigation of UCl4

Uranium chloride salts are a proposed fuel source for molten salt reactors (MSRs). However, despite their relevance to nuclear energy, they remain understudied, in part because of their air and moisture sensitivity. This work provides the first Raman spectra of UCl4 from 45 to 3200 cm−1 collected with 532 and 785 nm excitation sources as well as the assignment of 10 identi…

Overcoming Variability: A Reproducible Approach to SERS Detection of Nanodiamonds

Detonation nanodiamonds (DNDs) are formed at specific pressures and temperatures during explosions. Different explosives produce varied yields of DNDs within their detonation soot, with Composition B producing the highest yield. Raman spectroscopy (RS) is often used for the characterization of sp2- and sp3-hybridized carbon allotropes in carbonaceous materials because of d…
