Low-temperature synthesis of nanosized bismuth ferrite by the soft chemical method
(2013-01-01)
This paper describes research on a simple low-temperature synthesis route to prepare bismuth ferrite nanopowders by the polymeric precursor method using bismuth and iron nitrates. BiFeO 3 (BFO) nanopowders were characterized ...
Antibacterial activity, cytocompatibility and effect of Bio-C Temp bioceramic intracanal medicament on osteoblast biology
(2021-01-01)
Aim: To analyse the antimicrobial and biological properties of a new bioceramic intracanal medicament (Bio-C Temp), and to compare it with two calcium hydroxide-based intracanal medicaments (Calen® and UltraCal® XS). ...
Estimate of experimental yield for two-photon absorption in helium

Fish exposure to nano-TiO2 under different experimental conditions: Methodological aspects for nanoecotoxicology investigations
(2013-10-01)
The ecotoxicology of nano-TiO2 has been extensively studied in recent years; however, few toxicological investigations have considered the photocatalytic properties of the substance, which can increase its toxicity to ...
Furan interaction with the Si(001)-(2 x 2) surface: structural, energetics, and vibrational spectra from first-principles
(IOP PUBLISHING LTD, 2009)
In this work we employ the state of the art pseudopotential method, within a generalized gradient approximation to the density functional theory, to investigate the adsorption process of furan on the silicon (001) surface. ...
Preparation and characterization of a red luminescent composite composed of an EVA copolymer and a Y3BO6:Eu3+ phosphor
(2017-01-01)
This work describes the preparation of red luminescent composites based on an ethylene/vinyl acetate (EVA) copolymer filled with a Y3BO6:Eu3+ phosphor powder. Luminescent powders were synthesized using a method derived ...
Cobalt selenate pentahydrate: Thermal decomposition intermediates and their properties dependence on temperature changes
(2020-07-01)
Several new materials based on selenates and selenites have been produced, characterized and their application have exhibited good results in several areas. As consequence, some selenates/selenites that had been synthetized ...
Causal perturbation theory approach to Yukawa’s model
(2021-09-01)
Neutral Yukawa’s model for the description of the interaction between nucleons and pions is studied in the framework of causal perturbation theory, an axiomatic S-matrix quantum field theory in which ultra-violet divergences ...
TiO2 thin film growth using the MOCVD method
(ABM, ABC, ABPol, 2001-07)
Titanium oxide (TiO2) thin films were obtained using the MOCVD method. In this report we discuss the properties of a film, produced using a ordinary deposition apparatus, as a function of the deposition time, with constant ...
Phenological aspects of Syngonanthus elegans (Bong.) Ruhl. (Eriocaulaceae) from Serra do Cipo - MG. Brazil
(Inst Tecnologia Parana, 1997-01-01)
S. elegans (Eriocaulaceae) is known in Brazil as star flower and is used economically for ornamental purposes. The fact that there is no control over its collection, brings about great damage to its population. Thus the ...
