The morphology of bone mineral crystals

Calcified Tissue Research, 1978
Electron microscopical observations of the size and shape of bone mineral crystallites have not been in complete agreement with X-ray diffraction findings. The two prevalent viewpoints consider bone mineral crystals to be either rod, or plate like in habit.

Comparative Analysis of Cuticular Wax in Various Grape Cultivars During Berry Development and After Storage

Frontiers in Nutrition, 2021
Cuticular wax covering the surface of fleshy fruit is closely related to fruit glossiness, development, and post-harvest storage quality. However, the information about formation characteristics and molecular mechanisms of cuticular wax in grape berry is

Three-dimensional nanostructure determination from a large diffraction data set recorded using scanning electron nanodiffraction

IUCrJ, 2016
A diffraction-based technique is developed for the determination of three-dimensional nanostructures. The technique employs high-resolution and low-dose scanning electron nanodiffraction (SEND) to acquire three-dimensional diffraction patterns, with the ...

Effects of ammonium citrate additive on crystal morphology of aluminum phosphate ammonium taranakite

, 2009
In this communication, we demonstrated the growth of aluminum phosphate ammonium taranakite (NH(4)-AlPO(4)) crystals from regular hexagonal form into the disk-like form could be controlled by ammonium citrate (AMC) as the effective crystal growth ...

Effect of Ionic Liquids on the Separation of Sucrose Crystals from a Natural Product Using Crystallization Techniques

Crystals, 2017
The present work aims to investigate the applicability of ionic liquids (ILs) for natural ingredient crystallization. First, the medicinal plant, namely Angelica gigas Nakai, was extracted using methanol (MeOH) as a solvent.

Growth and morphology of C60 crystals [PDF]

Chemical Physics Letters, 1992
Abstract Single crystals of pure C 60 are grown from the vapour phase. The crystal morphology is compared to the theoretical equilibrium form, predicted on the basis of a periodic bond chain analysis and a statistical mechanical approach. Some interesting growth phenomena are observed and discussed.

The effect of SU-8 patterned surfaces on the response of the quartz crystal microbalance [PDF]

, 2005
In this work we present data showing the effect of patterning layers of SU-8 photoresist on a quartz crystal microbalance (QCM) and subsequent chemical treatment to increase their hydrophobicity. Patterns with 5 mu m diameter pillars spaced every 10 mu m

Disorder in Extra-Large Pore Zeolite ITQ-33 Revealed by Single Crystal XRD

, 2013
The single crystal of the extra-large pore zeolite, ITQ-33, was obtained and used to explore its crystal structure details. The ITQ-33 structure was found to be disordered with the columnar periodic building unit, explaining the morphology changes upon ...

Insight into the Formation of Glimepiride Nanocrystals by Wet Media Milling

Pharmaceutics, 2020
Nanocrystal formation for the dissolution enhancement of glimepiride was attempted by wet media milling. Different stabilizers were tested and the obtained nanosuspensions were solidified by spray drying in presence of mannitol, and characterized ...

Structure and Morphology of Indole Analogue Crystals [PDF]

ACS Omega, 2020
Indole and six simple analogues were crystallized in different environments to study the crystal habit changes. All crystal structures were determined by X-ray diffraction experiments. Lattice energies based on DFT-D3 periodic calculations and framework analysis were used to define the most important intermolecular interactions in the crystal ...
