Structural Dynamics of Chloromethanes through Computational Spectroscopy: Combining INS and DFT

open access: yesMolecules, 2022
In this work, the structural dynamics of the chloromethanes CCl4, CHCl3 and CH2Cl2 were evaluated through a computational spectroscopy approach by comparing experimental inelastic neutron scattering (INS) spectra with the corresponding simulated spectra ...

Direct iminization of PEEK [PDF]

open access: yes, 2011
Semi-crystalline poly(ether ketone)s are important high-temperature engineering thermoplastics, but are difficult to characterize at the molecular level because of their insolubility in conventional organic solvents.

A Simplified Method for Anionic Surfactant Analysis in Water Using a New Solvent

open access: yesToxics, 2022
Anionic surfactants (AS) are becoming a major emerging contaminant of waters due to their widespread use in household and industrial products. The standard chloroform method for analysis of AS in water relies on chloroform extraction of a methylene blue ...
