The effect of temperature and sulfolane concentration on aqueous electrolyte with molecular crowding: A molecular dynamics simulation study

AIP Advances, 2023
Molecular crowding agents can significantly suppress water activity by affecting hydrogen bonds. Here, we performed molecular dynamics simulation to study the effect of temperature and concentration of sulfolane, a crowding agent, on aqueous electrolytes.

Do Hydrogen Bonds Influence Excitonic Splittings?

CHIMIA, 2016
The excitonic splitting and vibronic quenching of the inversion-symmetric homodimers of benzonitrile, (BN)2, and meta-cyanophenol, (mCP)2, are investigated by two-color resonant two-photon ionization spectroscopy.

The Nature of Hydrogen Bonds: A Delineation of the Role of Different Energy Components on Hydrogen Bond Strengths and Lengths

Chemistry - An Asian Journal, 2019
Hydrogen bonds are a complex interplay between different energy components, and their nature is still subject of an ongoing debate. In this minireview, we therefore provide an overview of the different perspectives on hydrogen bonding.

4-Amino-1H-1,2,4-triazol-1-ium nitrate

Acta Crystallographica Section E, 2011
The non-centrosymmetric crystal structure of the novel semi-organic title compound, C2H5N4+·NO3−, is based on alternating layers of 4-amino-1H-1,2,4-triazolinium cations (formed by parallel chains of cations mediated by weak C& ...

Side chain to main chain hydrogen bonds stabilize a polyglutamine helix in a transcription factor

Nature Communications, 2019
Polyglutamine (polyQ) tracts are regions of low sequence complexity frequently found in transcription factors. Tract length often correlates with transcriptional activity and expansion beyond specific thresholds in certain human proteins is the cause of ...
