This review article lead by Daniel Vallejo and Joe Corstvet entitled “Triboelectric nanogenerators: Low-cost power supplies for improved electrospray ionization” published in the International Journal of Mass Spectrometry highlights the fundamentals of ESI driven by DC power supplies, its contrasting qualities to triboelectric nanogenerator power supplies, and its applications to three distinct fields of research: forensics, metabolomics, and protein structure analysis.

Francesc Labad Roig, a Graduate student at the Universitat de Barcelona, from Barcelona, Spain joins the group! He comes from the Consejo Superior de Investigaciones Científicas (CSIC) under the supervision of Dra. Sandra Pérez and Dr. Enric Vázquez. He will be here for almost six months (July-December) in order to use ion mobility instrumentation to separate and analyze very persistent and very mobile (vPvM) substances such as melamine or PFAs from urban waters (mainly groundwater) from Atlanta. The main instrumentation used will be the Synapt G2S coupled to a Q-ToF. This work is in the frame of the UPWATER project. Francesc is enjoying an FPI 2019 grant from the Spanish ministry.

Titled “Development of a Machine Learning Strategy for Quantitative Non-targeted Lipidomics” Alex gave a talk at the 2023 Metabolomics Society Meeting in Niagara Falls, Canada

This work lead by Alex Van Grouw entitled “Development of a Robust Consensus Modeling Approach for Identifying Cellular and Media Metabolites Predictive of Mesenchymal Stromal Cell Potency” published in Stem Cells establishes a generalizable framework for identifying consensus predictive metabolites that predict MSC function, as well as guiding future MSC manufacturing efforts through identification of high-potency MSC lines and metabolic engineering.
