Calcium oxalate crystals in halo-xerophytic species and their macropatterns trends: The importance of a multivariate analysis considering soil characteristics
(Elsevier Gmbh, 2017-09)
The morphological characteristics of calciphytoliths and description of their macro and micropattern in leaves of halo-xerophytic species of the Salitral de la Vidriera, Argentina, were carried out. Additionally, a ...
Epoxy networks containing large mass fractions of a monofunctional Polyhedral Oligomeric Silsesquioxane (POSS)
(American Chemical Society, 2003-05)
A polyhedral oligomeric silsesquioxane (POSS) containing one epoxy group and seven isobutyl groups per molecule was incorporated into an epoxy network following a two-stage process. In the first stage, POSS was reacted ...
Comparative study of first- and second-order Raman spectra of MWCNT at visible and infrared laser excitation
(Pergamon-elsevier Science LtdOxfordInglaterra, 2006)
Monofunctional epoxy-POSS dispersed in epoxy - Amine networks: Effect of a prereaction on the morphology and crystallinity of POSS domains
(American Chemical Society, 2007-02)
Several studies have recently reported the use of monofunctional octahedral oligomeric silsesquioxanes (monofunctional POSS) to modify polymer networks. In most of these studies the final material is depicted as a network ...
Nucleation kinetics of crystalline phases from a kaolinitic body used in the processing of red ceramics
(Elsevier B.V., 2011-04-01)
The crystallization kinetics of red ceramic raw material from the western part of São Paulo State, Brazil, was examined by differential thermal analysis (DTA) and X-ray diffraction (XRD). The chemical composition of the ...

Carlhintzeite, Ca2AlF7•H2O, from the Gigante granitic pegmatite, Córdoba province, Argentina: Description and crystal structure
(Mineralogical Soc, 2010-08)
Carlhintzeite, Ca2AlF7•H2O, has been found at the Gigante pegmatite, Punilla Department, Córdoba Province, Argentina. It occurs as colourless prismatic crystals up to 0.8 mm long, ubiquitously twinned on {001}. Electron ...
Effects of surface stability on the morphological transformation of metals and metal oxides as investigated by first-principles calculations
(2015-09-17)
Morphology is a key property of materials. Owing to their precise structure and morphology, crystals and nanocrystals provide excellent model systems for joint experimental and theoretical investigations into surface-related ...
