Estudo da cristalização de lactose em diferentes solventes
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2007-02-23)
In the study of the lactose crystallization process, the nucleation phenomena and
crystalline growth have been evaluated, when the systems were submitted to different solvent
and operational conditions.
The solubility s ...
Calcium oxalate crystals in plant communities of the southeast of the Pampean Plain, Argentina
(Springer Tokyo, 2018)
Calcium oxalate crystals (COC) are one of the most prevalent and widely distributed biomineralizations in plants. The aim of this work is to analyze and compare the data previously reported about the presence and production ...
Solution crystallization kinetics of 6-aminopenicillanic acid

Effect of surface hydrophobicity distribution on retention of ribonucleases in hydrophobic interaction chromatography
(ELSEVIER, 2004-07-16)
The effect of surface hydrophobicity distribution of proteins on retention in hydrophobic interaction chromatography (HIC) was investigated. Average surface hydrophobicity as well as hydrophobic contact area between protein ...
Batch cooling crystallization of xylitol produced by biotechnological route
(JOHN WILEY & SONS LTD, 2009)
BACKGROUND: This work deals with the xylitol production by biotechnological routes emphasizing the purification process using crystallization. RESULTS: Xylitol volumetric productivity of 0.665 g L(-1) h(-1) and yield of ...
SAXS measurements of the porosity in Cu(II)-doped SnO2 xerogels during crystallization
(1997-08-01)
The small-angle X-ray scattering (SAXS) technique was used to study the porosity which develops in Cu(II)-doped SnO2 monolithic xerogels during crystallization. The influence of the upper temperature of heat-treatment and ...

Size characterization of anatase TiO2 nanoparticles using a crystal size distribution in the LO Raman mode
(2009)
Optical applications of TiO2 nanoparticles depend directly on their size and phase. The sol gel process is widely used to obtain TiO2 nanoparticles. We obtained TiO2 nanoparticles with different sizes by varying the water ...
Nuevo procedimiento para analizar crystal size distributions y cálculo de T y PH20 en sistemas magmáticos a través de un modelo acoplado de parámetros cinéticos de cristalización con la composición de plagioclasa. Aplicaciones en el volcán Villarica (Chile) y en el volcán Lassen Peak (EEUU)
(Universidad de Chile, 2015)
El presente trabajo presenta un nuevo método para desarrollar Crystal Size Distributions (CSD), un tipo de análisis textural cuantitativo que compara la densidad de población de cristales respecto a su tamaño. Basado en ...
Modeling of disorder effects and optical extinction in three-dimensional photonic crystals
(American Physical Society, 2009-12)
We present three different methods for the modeling of disorder effects in three-dimensional photonic crystals. In order to reproduce experimental results, we apply a method based on a statistical distribution of sphere ...
