Strontium-substituted hydroxyapatite nanocrystals.
TL;DR: In this paper, the effect of relatively low levels of strontium concentration on the dimensions of the coherent length of the perfect crystalline domains and on the morphology of the nanocrystals is observed.

Non-parallel chains in crystalline γ-isotactic polypropylene
TL;DR: In this paper, the authors determined the crystal structure of the γ-form of isotactic polypropylene (γ-iPP) and showed that the structure comprises layers which are two chains wide, reminiscent of the α-phase, but with the chain-axis directions in adjacent bilayers at an angle of 80° to one another.

Composite Nanocrystals Provide New Insight on Alendronate Interaction with Hydroxyapatite Structure
Journal ArticleDOI
The effect of zoledronate-hydroxyapatite nanocomposites on osteoclasts and osteoblast-like cells in vitro
TL;DR: Data suggest a preferential interaction between zoledronate and the hydroxyapatite faces parallel to the c-axis direction, which would suggest an even greater influence of HA-ZOL than HA-AL on osteoclast apoptosis.
Book ChapterDOI
Electron crystallography of organic molecules
TL;DR: In this paper, the authors demonstrate how experimental diffraction intensity data or images can be used in structure analyses of a wide variety of organic and biological materials to yield results that can be compared favorably with X-ray crystal structures.

LALS: a linked-atom least-squares reciprocal-space refinement system incorporating stereochemical restraints to supplement sparse diffraction data
P. J. C. Smith,S. Arnott +1 more
TL;DR: LALS as discussed by the authors is a computer program for the refinement of molecular structures using X-ray structure factors, usually from fibre diffraction studies, and/or stereochemical information, including a comprehensive short-contact search.

The interpretation of quasi-kinematical single-crystal electron diffraction intensity data from paraffins
TL;DR: In this article, single-crystal hk0 electron diffraction patterns from thin ( ≤ 240 A) rhomboid n-hexatriacontane (n-C36H74) crystals contain intensity data which are well fit by the commonly observed O⊥ methylene subcell phasing model but not by a true unit cell model which contains two mutually displaced monolayers.

Refinement of linear polymer crystal structures determined from electron diffraction data
Barbara Moss,Douglas L. Dorset +1 more
TL;DR: In this article, the reliability of linear polymer structures determined by using electron diffraction data is investigated, and the results of n-beam dynamical calculations and kinematic calculations which take account of crystal bending are compared with experimental structure factors for five published structures.
