Crystallization dynamics on curved surfaces
(Amer Physical Soc, 2013-07)
We study the evolution from a liquid to a crystal phase in two-dimensional curved space. At early times, while crystal seeds grow preferentially in regions of low curvature, the lattice frustration produced in regions with ...
Particle growth during calcination of polycation oxides synthesized by the polymeric precursors method
The particle-growth kinetics of sodium niobate and zirconium titanate powders that were processed by the polymeric precursors method were studied. The growth kinetics that were studied for the particle, in the final stage ...
Structural characterization of single crystals of sodium titanate nanowires prepared by hydrothermal process
(ELSEVIER SCIENCE BV, 2008-07-15)
Na2Ti6O13 nanowires have been synthesized using a simple hydrothermal reaction at 130 1C between TiO2 particles and NaOH aqueous solution. Subsequently the samples were annealed at 500 1C in air for 24 h. Field emission ...
Layer double hydroxides for enhanced poly(3-hydroxybutyrate-co-3-hydroxyvalerate) crystallization
Crystallization of ZrF4-LaF3-AlF3 glasses
0.7125ZrF4-0.2375(1 - xLaF3 • xLnF3)-0.05AIF3 with x = 0.01, 0.02 and 0.03 for Ln = Er and x = 0.03 for Ln = Pr, Nd glasses were studied by differential thermal analysis (DTA), X-ray diffraction and optical spectroscopy. ...
Strategies for xylitol purification and Crystallization: A review
This paper reviews the literature on the main aspects of purification and crystallization of xylitol produced either by chemical or biotechnological routes. Different strategies have been used to clarify media containing ...
Growth kinetics of vanadium pentoxide nanostructures under hydrothermal conditions
The work reported here involved a study of the growth kinetics of V2O5nH2O nanostructures under hydrothermal conditions. The coarsening process of V2O5nH2O nanoribbons was followed by subjecting the as-prepared suspensions ...
An instrument for combining x-ray multiple diffraction and x-ray topographic imaging for examining crystal microcrystallography and perfection
