Influence of Terminal Functionality on the Crystal Packing Behaviour and Cytotoxicity of Aromatic Oligoamides

Frontiers in Chemistry, 2021
The synthesis and characterization of three aromatic oligoamides, constructed from the same pyridyl carboxamide core but incorporating distinct end groups of acetyl (Ac) 1, tert-butyloxycarbonyl (Boc) 2 and amine 3 is reported.

Crystallography for the People [PDF]

Acta Crystallographica Section A Foundations and Advances, 2013
The British Crystallographic Association (BCA) has engaged in public outreach projects over the past two years, aimed at communicating the basic principles and applications of crystallography to the general public, especially in light of the Bragg Centenary Celebrations and the International Year of Crystallography.

Namdinator – automatic molecular dynamics flexible fitting of structural models into cryo-EM and crystallography experimental maps

bioRxiv, 2018
Model building into experimental maps is a key element of structural biology, but can be both time consuming and error-prone. Here we present Namdinator, an easy-to-use tool that enables the user to run a Molecular Dynamics Flexible Fitting (MDFF ...

Amplification of UV radiation and gain mechanisms in ZnO films with loose-packed structure

Компьютерная оптика
The modern demands for miniaturization of optoelectronic devices, in particular, for the UV range, are inextricably linked with the improvement of fabrication technologies for the corresponding photonic nano/micro objects and the study of their radiative

Spikes in Cosmic Crystallography

, 2002
If the universe is multiply connected and small the sky shows multiple images of cosmic objects, correlated by the covering group of the 3-manifold used to model it.

The Search for Hydrogen Stores on a Large Scale; A Straightforward and Automated Open Database Analysis as a First Sweep for Candidate Materials

Crystals, 2015
The storage of hydrogen is considered as the bottleneck in the implementation of portable fuel cell power generating systems. The necessary experimental studies to discover and develop appropriate storage materials are always time-limited.

Crystallography in the 21st century [PDF]

IUCrJ, 2015
The field of crystallography, which has had a major impact on the sciences in the last 100 years, is continuing to expand scientific horizons as technical and conceptual boundaries are overcome. Structure-function-dynamics will become an integrated theme for many studies as will obtaining structures without the 'benevolent tyranny' of crystals.

An efficient method for LEED crystallography [PDF]

, 1990
Determination of periodic surface structures from analysis of LEED intensity data is usually based on the evaluation of continuous I/V-spectra for a large number of model structures for which all the structural parameters have to be refined ...
