Crystal structure of N-[(2-hydroxynaphthalen-1-yl)(4-methylphenyl)methyl]acetamide
Acta Crystallographica Section E: Crystallographic Communications, 2015 In the title molecule, C20H19NO2, the naphthalene ring system subtends a dihedral angle of 82.50 (7)° with the benzene ring and an intramolecular N—H...O hydrogen bond closes an S(6) ring.

Automatic physical phasing X-ray crystallography [PDF]
arXiv, 2004 Phase invariants are important pieces of information about the atomic structures of crystals. There are several mathematical methods in X-ray crystallography to estimate phase invariants. The multi-wave diffraction phenomenon offers a unique opportunity of physically measuring phase invariants.

Radical TADF: Quartet‐Derived Luminescence with Dark TEMPO
Advanced Materials, EarlyView.A new class of luminescent organic quantum materials is introduced, formed by attaching a stable radical to TADF chromophores. Due to ferromagnetic exchange coupling, a high‐spin quartet state forms upon excitation, which can thermally access a bright state.

Ultrasonic acoustic levitation for fast frame rate X-ray protein crystallography at room temperature
Scientific Reports, 2016 Increasing the data acquisition rate of X-ray diffraction images for macromolecular crystals at room temperature at synchrotrons has the potential to significantly accelerate both structural analysis of biomolecules and structure-based drug developments.

Advanced Materials, Volume 37, Issue 13, April 2, 2025.Metal‐covalent organic frameworks (MCOFs) are novel porous materials that exhibit the advantages of covalent and metal‐organic frameworks. However, it is extremely difficult to resolve their atomic structure and better understand their structure‐properties relation. This work utilizes a synergistic combination of advanced microscopy, spectroscopic, and

Protein Energy Landscapes Determined by 5-Dimensional Crystallography [PDF]
arXiv, 2013 Free energy landscapes decisively determine the progress of enzymatically catalyzed reactions[1]. Time-resolved macromolecular crystallography unifies transient-state kinetics with structure determination [2-4] because both can be determined from the same set of X-ray data.
