Tracing the evolution of baryonic matter from atoms in space to stars and planets hinges on an accurate understanding of the underlying chemical processes controlling the properties of the gas at every step along this pathway.  Here I will explain some of the key epochs in this cosmic cycle and highlight our laboratory studies into the underlying chemistry that controls the observed properties of the cosmos.
Theoretical & Experimental Studies of Small Molecules in Helium Nanodroplets: Anharmonic Modeling and Infrared Spectroscopy Peter R. Franke and Gary E. Douberly Various small, organic molecules of interest to atmospheric and combustion chemistry are interrogated with infrared action spectroscopy and ab inito computations. Molecules are solvated by helium nanodroplets, at temperatures of 0.4 K, and their mid-infrared spectra are measured with…
The conformation and post-translational modification (PTM) of a protein is critically important to its function. Mass spectrometry has been increasingly utilized to analyze both of these attributes. Acidic PTMs, like phosphorylation and sulfation however, present significant obstacles to analysis. Here, I present a series of techniques to overcome these issues and improve the annotation of these vital modifications. Lastly, I discuss the use of…
Sensing of ions is an integral part in bioanalysis and in the management of healthcare, water, the environment, and a range of industrial activities (e.g., agriculture and food processing). Traditionally, ion sensing was performed by sending samples to central test laboratories. Once the analysis is performed by the technician, the results are reported back to the customer or the healthcare provider. This process is time consuming and impedes…
