Ferroelectric and structural instability of (Pb,Ca)TiO3 thin films prepared in an oxygen atmosphere and deposited on LSCO thin films which act as a buffer layer
(2013-09-20)
Structural, microstructural and ferroelectric properties of Pb0.90Ca0.10TiO3 (PCT10) thin films deposited using La0.50Sr0.50CoO3 (LSCO) thin films which serve only as a buffer layer were compared with properties of the ...
One-step preparation of UV transparent highly ordered mesoporous zirconia thin films
(Royal Society of Chemistry, 2013-01)
Highly ordered mesoporous ZrO2 thin films were prepared by evaporation induced self-assembly. Complexing agents and low pH were simultaneously employed in order to control the hydrolysis-condensation kinetics, permitting ...
Charcoal production using tropical pine thinnings
(1992-08-01)
In Brazil, the wood from pine-plantation thinnings is difficult to sell. However, these wood thinnings could be used to produce charcoal. The physical and chemical properties of charcoal produced from logs or first and ...

Potentialities and practical limitations of absolute neutron dosimetry using thin films of uranium and thorium applied to the fission track dating
(Elsevier B.V., 1999-06-01)
Neutron dosimetry using natural uranium and thorium thin films makes possible that mineral dating by the fission-track method can be accomplished, even when poor thermalized neutron facilities are employed. In this case, ...
U and Th thin film neutron dosimetry for fission-track dating: Application to the age standard Moldavite
(2005-12-01)
Neutron dosimetry based on U and Th thin films was used for fission-track dating of the age standard Moldavite, the central European tektite, from the Middle Miocene deposit of Jankov (southern Bohemia, Czech Republic). ...
Homogenization in a thin domain with an oscillatory boundary
(GAUTHIER-VILLARS/EDITIONS ELSEVIER, 2011)
In this paper we analyze the behavior of the Laplace operator with Neumann boundary conditions in a thin domain of the type R(epsilon) = {(x(1), x(2)) is an element of R(2) vertical bar x(1) is an element of (0, 1), 0 < ...
Effect of pressure-assisted thermal annealing on the optical properties of ZnO thin films
(2012-12-21)
ZnO thin films were prepared by the polymeric precursor method. The films were deposited on silicon substrates using the spin-coating technique, and were annealed at 330°C for 32h under pressure-assisted thermal annealing ...
Photoluminescence of bulks and thin films of Eu3+-doped organic/inorganic hybrids
(Elsevier B.V. Sa, 2008-02-28)
Organic-inorganic hybrids formed by polyether-based chains grafted to both ends to a siliceous backbone through urea cross-linkages (-NHC=O)NH-), named di-ureasil, have been used as host for incorporation of Eu3+ in the ...
Piezoresponse behavior of niobium doped bismuth ferrite thin films grown by chemical method
(Elsevier B.V. Sa, 2010-03-18)
This paper focuses on the piezoresponse characteristics at room temperature in niobium modified bismuth ferrite thin films (BFN) deposited on Pt/TiO(2)/SiO(2)/Si (1 0 0) substrates by the soft chemical method. The obtained ...
