Rapid Communications in Mass Spectrometry, EarlyView.ABSTRACT Rationale In this study, we applied cross‐linking mass spectrometry (XL‐MS) to characterize the oligomeric states of a PGLa/magainin 2 mixture and gain insight into the heterodimerization previously suggested in the literature. Both peptides have shown a synergistic enhancement of activity when tested in antimicrobial assays; however, the ...

Acid Resistant and Highly Silver Selective Membranes Based on Charged Nanoporous 2D‐Materials
Small, EarlyView.In this work, new membranes based on charged & nanoporous nanosheets with unprecedented selectivity to silver versus a wide range of other metallic ions are reported. Furthermore, a demonstrated and lead specific intralamellar lead pathway is demonstrated. A potential applicability for ubiquitous silver in WEEE is validated.

Oxidation Products of S-Adenosyl Methionine Probed by Infrared Multiple Photon Dissociation Spectroscopy. [PDF]
ChemphyschemHO•‐induced oxidation is structurally resolved in S‐adenosyl methionine (SAM). Infrared multiple photon dissociation (IRMPD) spectroscopy and density functional theory (DFT) calculations reveal clear spectroscopic signatures of adenine C8 oxidation. S‐adenosyl methionine (SAM) is a key biomolecule in cellular processes, acting as a primary methyl donor,

Small, EarlyView.A bis formamide molecule was found to feature afterglow properties, in both crystalline powder state and in polyvinyl alcohol films. This was attributed to the intermolecular packing that allows H‐trapped emitting state and/or clustering‐triggered emission, which was intensified upon insertion of tetramethylbenzidine as a doping agent.

Unforgeable Red: Design and Application of SO‐Annulated Perylene Diimides for Anti‐Counterfeiting
Small, EarlyView.Sulfoxide‐annulated derivatives were synthesized as photoactive chromophores and implemented in photopatterning processes to design anti‐counterfeiting signatures with a double level of authentication. Patterns ranging from centimeter to micrometer size were obtained with high definition, and thereafter these approaches were tested in potential market ...
