Superior Adhesion of Monolayer Amorphous Carbon to Copper

The single‐atom thickness of graphene holds great potential for device scaling, but its effectiveness as a thin metal‐ion diffusion barrier in microelectronics and a corrosion barrier for plasmonic devices is compromised by weak van der Waals interactions ...

Oligomers of diphenylalanine examined using cold ion spectroscopy and neural network-based conformational search

Oleg Boyarkine, Ruslan Yamaletdinov, Vladimir Kopysov

Diphenylalanine (Phe2) is the primary building block of many self-assembling nanostructures that are important in biology and materials science. Understanding the detailed mechanism of their formation requires knowledge of the structural motives that the s ...

Quantification of enantiomers and blind identification of erythro-sphingosine non-racemates by cold ion spectroscopy

Oleg Boyarkine, Ruslan Yamaletdinov, Vladimir Kopysov

Enantiomers of a lipid erythro-sphingosine have been quantified with ≈4% accuracy by UV cold ion spectroscopy of their non-covalent complexes with a chiral aromatic molecule. The diastereomeric configuration of such complexes enables the quantification usi ...

Revealing the Structure of Tryptophan in Microhydrated Complexes by Cold Ion Spectroscopy

Natalia Nagornova, Oleg Boyarkine, Andrei Zviagin, Ruslan Yamaletdinov, Manuel Dömer

The geometry of biomolecules isolated in the gas phaseusuallydiffers substantially from their native structures in aqueous solution,which are the only ones truly relevant to life science. To connectthe high resolution of cold ion spectroscopy that can be a ...

Identification of Isomeric Lipids by UV Spectroscopy of Noncovalent Complexes with Aromatic Molecules

Oleg Boyarkine, Ruslan Yamaletdinov

The tremendous structural and isomeric diversity of lipids enables a wide range of their functions in nature but makes the identification of these biomolecules challenging. We distinguish and quantify isomeric lipids using cold ion UV fragmentation spectro ...

Revealing Single-Bond Anomeric Selectivity in Carbohydrate-Protein Interactions

Oleg Boyarkine, Ruslan Yamaletdinov, Aleksandr Pereverzev, Viktoriia Aladinskaia

The noncovalent binding of proteins to glycans is amazingly selective to the isoforms of carbohydrates, including alpha/beta anomers that coexist in solution. We isolate in the gas phase and study at the atomic level the simplest model system: noncovalent ...

Interplay of H-Bonds with Aromatics in Isolated Complexes Identifies Isomeric Carbohydrates

Oleg Boyarkine, Ruslan Yamaletdinov, Vladimir Kopysov, Aleksandr Pereverzev

The tremendous isomeric diversity of carbohydrates enables a wide range of their biological functions but makes the identification and study of these molecules difficult. We investigated the ability of intermolecular interactions to communicate structural ...
