How Strong Is the Hydrogen Bond in Hybrid Perovskites?

open access: yesJournal of Physical Chemistry Letters, 2017
Hybrid organic–inorganic perovskites represent a special class of metal–organic framework where a molecular cation is encased in an anionic cage. The molecule–cage interaction influences phase stability, phase transformations, and the molecular dynamics.

Quantum delocalization of protons in the hydrogen-bond network of an enzyme active site [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2014
Significance Because of the low mass of the proton, nuclear quantum effects can dramatically alter the properties of hydrogen-bond networks, especially when short and strong hydrogen bonds occur.

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

open access: yesFEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Quantifying hydrogen bonding using electrically tunable nanoconfined water

open access: yesNature Communications
Hydrogen bonding plays a crucial role in biology and technology, yet it remains poorly understood and quantified despite its fundamental importance. Traditional models, which describe hydrogen bonds as electrostatic interactions between electropositive ...

l-Alanine hydrochloride monohydrate

open access: yesActa Crystallographica Section E, 2008
Colorless crystals of l-alanine hydrochloride monohydrate, C3H8NO2+·Cl−·H2O, were obtained from a powder sample that had been left standing in a refrigerator for a few years.

Effect of the Hydration Shell on the Carbonyl Vibration in the Ala-Leu-Ala-Leu Peptide

open access: yesMolecules, 2021
The vibrational spectrum of the Ala-Leu-Ala-Leu peptide in solution, computed from first-principles simulations, shows a prominent band in the amide I region that is assigned to stretching of carbonyl groups.

Golden sections of inter-atomic distances as exact ionic radii of atoms [PDF]

open access: yes, 2009
The Golden ratio which appears in the geometry of a variety of creations in Nature is found to arise right in the Bohr radius of the hydrogen atom due to the opposite charges of the electron and proton.
