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 ...
Accelerated microwave-assisted hydrothermal/solvothermal processing: Fundamentals, morphologies, and applications
(2018-06-01)
This article is designed to serve as a roadmap for understanding the fundamentals, the key advantages and the potential applications of microwave-assisted hydrothermal/solvothermal (MAH/S) processing. MAH/S synthesis is a ...
Dispersed lipid liquid crystalline phases stabilized by a hydrophobically modified cellulose
(2007-02-27)
Aqueous dispersions of monoolein (MO) with a commercial hydrophobically modified ethyl hydroxyethyl cellulose ether (HMEHEC) have been investigated with respect to the morphologies of the liquid crystalline nanoparticles. ...
Effect of la doping on the crystal structure, electric, magnetic and morphologic properties of the BSCCO system
(2017-10-01)
Studies of the doping process can provide a better understanding of the superconducting mechanisms in cuprous oxide materials. In this work, we studied the doping effects on the crystal structure, electric, morphologic and ...
Influence of oxygen flow on crystallization and morphology of PLZT thin films
(Elsevier B.V., 2002-01-01)
PLZT thin films were prepared by a dip coating process using Pechini's method, also known as polymeric precursor method. The PLZT solution was obtained from a mixture of the individual cation solutions and the process to ...
Influence of chemical interesterification on thermal behavior, microstructure, polymorphism and crystallization properties of canola oil and fully hydrogenated cottonseed oil blends
(ELSEVIER SCIENCE BV, 2009)
This work evaluated chemical interesterification of canola oil (CaO) and fully hydrogenated cottonseed oil (FHCSO) blends, with 20%, 25%, 30%, 35% and 40%(w/w) FHCSO content. Interesterification produced reduction of ...
Optical sensor platform based on cellulose nanocrystals (CNC) – 4′-(hexyloxy)-4-biphenylcarbonitrile (HOBC) bi-phase nematic liquid crystal composite films
(2017-07-15)
The preparation of composite materials has gained tremendous attention due to the potential synergy of the combined materials. Here we fabricate novel thermal/electrical responsive photonic composite films combining cellulose ...
Effect of cooling induced crystallization upon the properties of segmented thermoplastic polyurethanes
(De Gruyter, 2016-09)
An investigation on the cooling-induced crystallization in three thermoplastic polyurethanes based on MDI, PTMG, and 1,4-BD as chain extender with differenthard segment content is reported. Thermal transitions were determined ...
Preparation of 9.5/65/35 PLZT powders by organic precursor method
(2001-01-01)
In this study the preparation of 9.5/65/35 PLZT ceramic powders were investigated. The powders with the formula Pb0.905La0.095(Zr0.65 Ti0.35)0.976O3 + 3.5 w% PbO were prepared using Pechini process and partial oxalate ...
Mechanism of the formation and properties of antimony polyphosphate
(2005-07-01)
Formation of antimony polyphosphate using Sb2O3 and/or (NH4)2HPO4 and NH4H 2PO4 as starting materials has been simulated by thermal analysis technique. The elimination of water and ammonia molecules induced by heating leads ...
