Crystallization behavior of random ethylene–butene copolymers modified with organic peroxide
(Elsevier Science, 2011-11-02)
The effect of chemical cross-linkage on the crystallization of random ethylene-1-butene copolymers obtained from hydrogenation of model polybutadiene was studied by means of Differential Scanning Calorimetry. The copolymers ...
Thermally reversible light scattering films based on the melting/crystallization of organic crystals dispersed in an epoxy matrix
(Pergamon-Elsevier Science Ltd, 2006-04-08)
Films that can be reversibly switched from opaque to transparent states by varying temperature (TRLS films), have potential applications in thermal sensors, optical devices, recording media, etc. A dispersion of organic ...
Gas antisolvent crystallization of organic salts from aqueous solutions
(Elsevier Science, 2000-06)
The selection of process conditions for the crystallization of an organic salt for pharmaceutical applications is studied in the present work. The crystallization process is carried out using the gas anti-solvent (GAS) ...
Calcium oxalate crystal production and density at different phenological stages of soybean plants (Glycine max L.) from the southeast of the Pampean Plain, Argentina
(German Society for Plant Sciences and the Royal Botanical Society of the Netherlands, 2016)
Templated CaCO3 Crystallization by Submicrometer and Nanosized Fibers
Electrospun submicrometer-sized poly(e-caprolactone) (PCL) meshes and nanosized multiwalled carbon nanotubes (MWCNTs) were used as a template for preparing porous and interconnected inorganic organic hybrid materials ...
Order induced charge carrier mobility enhancement in columnar liquid crystal diodes
(American Chemical Society - ACSWashington, DC, 2013-11)
Discotic molecules comprising a rigid aromatic core and flexible side chains have been promisingly applied in OLEDs as self-organizing organic semiconductors. Due to their potentially high charge carrier mobility along the ...
Effects of annealing on the crystallization and roughness of PLZT thin films
(Elsevier B.V., 2001-03-01)
Lead lanthanum zirconate titanate (PLZT) thin films with stoichiometry (9/65/35) were prepared by a dip-coating process using a polymeric organic solution. The solution viscosity was adjusted in the range of 15-56 cP. ...
Crystallography and the liquid crystal phase: a new approach to structural studies on a thermo-tropic smectic Schiff base
(Taylor & Francis Ltd, 2018-01)
In spite of the apparent contradiction between ‘liquid crystals’ (LC, materials exhibiting some degree of disorder) and ‘crystallography’ (a paradigmatic ordered kingdom), X-ray diffraction (XRD) studies make a substantial ...
HYDROGEN-BONDED SUPRAMOLECULAR ARRAY IN THE CRYSTAL STRUCTURE OF ETHYL 7-HYDROXY-2-OXO-2H-CHROMENE-3-CARBOXYLATE MONOHYDRATE
(Sociedad Chilena de Química, 2011)
Vibrational and Thermal Properties of Crystalline Topiramate
(Soc Brasileira Quimica, 2008-01-01)
Topiramate, a powerful anticonvulsant drug, was investigated by X-ray diffractometry, FT-Raman, FT-IR, TGA and DTA techniques as well as by DFT calculations. From this study it was possible to tentatively assign most of ...
