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 ...
Blends of i-PP and SBS. I. Influence of the in situ compatibilization on the morphology
(Wiley-blackwellHobokenEUA, 2002)
Molecularly imprinted hydrogels from colloidal crystals for the detection of progesterone
(Wiley, 2014-12)
The synthesis of new nanoporous materials based on molecularly imprinted polymers (MIPs) is investigated. The novel procedure combines the non-covalent imprinting method with the colloidal crystal template technique to ...
Structural and surface morphology characterizations of oriented LiNbO3 thin films grown by polymeric precursor method
(1999-06-01)
Polymeric precursor solution was used to deposit LiNbO3 thin films by dip coating on sapphire substrates. The effects of processing variables, such as heat treatment conditions and number of deposited layers, on crystallinity ...
Mechanism of Antibacterial Activity via Morphology Change of α-AgVO3: Theoretical and Experimental Insights
(2017-04-05)
The electronic configuration, morphology, optical features, and antibacterial activity of metastable α-AgVO3 crystals have been discussed by a conciliation and association of the results acquired by experimental procedures ...
Surface morphology and structural modification induced by femtosecond pulses in hydrogenated amorphous silicon films
(Amer Scientific Publishers, 2015-03-01)
This work investigates the modification, resulting from fs-laser irradiation (150 fs, 775 nm and 1 kHz), on the structure and surface morphology of hydrogenated amorphous silicon (a-Si:H) thin films. The sample morphology ...
Influence of the solution pH on the morphological, structural and electrical properties of Bi3.50La0.50Ti3O12 thin films obtained by the polymeric precursor method
(Elsevier B.V., 2005-09-01)
Lanthanum-doped Bi4Ti3O12 thin films (BLT) were deposited on Pt/Ti/SiO2/Si substrates using a polymeric precursor solution. The spin-coated films were specular, crack-free and crystalline after annealing at 700 degrees C ...
Structural, morphological and optical investigation of beta-Ag2MoO4 microcrystals obtained with different polar solvents
(Royal Soc Chemistry, 2015-01-01)
This communication reports the formation of beta-silver molybdate (beta-Ag2MoO4) microcrystals synthesized by a simple precipitation method using different polar solvents (water, methanol, ethanol, 1-propanol and 1-butanol). ...
Morphological evolution and visible light-induced degradation of Rhodamine 6G by nanocrystalline bismuth tungstate prepared using a template-based approach
(2016-09-01)
The cleaning of water contaminated with organic dyes is a crucial problem nowadays. The search for good catalysts is intense, and bismuth tungstates have attracted a lot of attention because of their catalytic properties ...
