Despite the ready tunability and industrial promise of deep eutectic solvents (DESs), there have been few x-ray spectroscopy studies at their liquid/vapor interfaces—which is relevant for their use in applications such as greenhouse-gas capture. Here, researchers probed the liquid/vapor interface of a benchmark DES using complementary spectroscopies. Read more »
Nicotine Protonation in Simulated Vaping Aerosols
To better understand how e-cigarette additives alter nicotine chemistry and users’ perceptions of vaping, researchers used x-ray spectroscopy technology at the Advanced Light Source to analyze the acid-base equilibria of additive-enhanced nicotine in simulated vaping aerosols. Read more »
Chemical (and Strategic) Transformations at Beamline 9.0
The Chemical Dynamics beamline, used for gas-phase vacuum ultraviolet (VUV) experiments, was one of the first beamlines built at the ALS. Since then, the program has undergone several strategic transformations, enabling the study of complexity in clusters, aerosols, and nanoparticles using both VUV and soft x-ray radiation. Read more »
