A model heterogeneous mixture of a hydrophilic tripeptide (phenylalanine-glycine-glycine, PGG) and hydrophobic organic acids ((12)C- and (13)C-octanoic acid and pentadecanoic acid) was subjected to electrospray ionization mass spectrometry (ESI-MS). The objective was to verify the previously noted inconsistencies in ESI-MS

The objective of this work is the further systematic improvement of the accuracy of Double-Hybrid Density Functionals (DHDF) that add non-local electron correlation effects to a standard hybrid functional by second-order perturbation theory (S. Grimme, J. Chem. Phys., 2006, 124

A simple, new way to introduce fragile biomolecules into the gas phase via thermal vaporization of nanoparticles is described. The general utility of this technique for the study of biomolecules is demonstrated by coupling this source to tunable synchrotron vacuum
Hypercrosslinked polymers (HCPs) are currently receiving great attention due to their unique characteristics and potential uses in diverse areas. However, the field of HCPs for open-tubular capillary electrochromatography (OT-CEC) separations has not been explored. Here, a knitted aromatic polymer (KAP)
