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 ...
Impact of defects on the electrical properties of BiFeO3 thin films
(Taylor & Francis Ltd, 2020-02-17)
The impact of defects on the electrical properties of bismuth ferrite thin films has been studied. Secondary phases and oxygen vacancies were the main defects considered. Thin films with secondary phases show higher ...
Thinly traded securities and risk management
(Universidad de Chile, Departamento de Economía, 2014-06)
Thinly traded securities exist in both emerging and well developed markets. However, plausible estimations of market risk measures for portfolios with infrequently traded securities have not been explored in the literature. ...
Problems related to the employment of thin uranium films as neutron dosimeters
(1995-12-01)
Thin uranium films built on muscovite mica basis and obsidian samples having known ages were irradiated with thermal neutrons at the IPEN/CNEN reactor, São Paulo. Comparing thin film performance with the obsidian one, it ...

Structural, dielectric, ferroelectric and optical properties of PBCT, PBST and PCST complex thin films on LaNiO3 metallic conductive oxide layer coated Si substrates by the CSD technique
(Elsevier B.V., 2014-10-05)
Ferroelectric thin films and LaNiO3 (LNO) metallic conductive oxide thin films were prepared by a chemical solution deposition (CSD) method. PBCT60, PBST60 and PCST60 ferroelectric thin films were grown on different ...
The improvement of thin polymer film properties through plasma immersion ion implantation and deposition technique
(2001-12-01)
Thin polymer films were deposited from acetylene and argon mixtures by plasma immersion ion implantation and deposition. The effect of the pulse frequency, v, on molecular structure, optical gap, contact angle and hardness ...

Cylindrical thin-shell wormholes and energy conditions
(World Scientific, 2012-02)
We prove the impossibility of cylindrical thin-shell wormholes supported by matter satisfying the energy conditions everywhere, under reasonable assumptions about the asymptotic behavior of the in general differentmetrics ...
