A recent study published in the Journal of the American Chemical Society presents an in-depth analysis of how ATP (adenosine triphosphate) in aqueous solutions interacts with magnesium ions. Conducted by researchers from the Department of Molecular Physics at the Fritz Haber Institute, in collaboration with the University of Chemistry and Technology Prague, the University of California, Berkeley, and the University of Southern California, the paper titled "How Does Mg2+(aq) Interact with ATP(aq)? Biomolecular Structure through the Lens of Liquid-Jet Photoemission Spectroscopy" introduces Liquid-Jet Photoemission Spectroscopy (LJ-PES) as a method for probing the electronic structure of this biomolecule in a complex aqueous-solution environment.
