Image potential state Influence on Charge Exchange in Li+ - Metal Surface Collisions
(American Chemical Society, 2014-04)
The energy dependence of the neutral fraction of ions scattered by metal surfaces is observed to be affected by the presence of energy gaps and surface states in their surface band structure. The effect is more dramatic ...
NaNbO3/PVDF COMPOSITE: A FLEXIBLE FUNCTIONAL MATERIAL
(Wiley-Blackwell, 2017-01-01)
Sodium niobate can be used as precursor of flexible composites with great properties aiming the use in devices that combine properties like piezoelectricity and photoluminescence. In this work, we obtained NaNbO3 fiber-like ...
Bamboos and lianas affect tree regeneration and microclimate in a semi-deciduous Atlantic forest
(Elsevier Science, 2007-12)
We assessed the effect of native bamboo and lianas on microclimate, tree regeneration and forest structure in a semi-deciduous Atlantic Forest subjected to selective timber extraction during the last century. We hypothetized ...
Brazing of UNS S32101 and UNS S32304 lean duplex stainless steels and UNS S32750 super duplex with AWS A5.3 BNi-7 (Ni–Cr–P) filler metal.
(Taylor & FrancisLondon, 2015)
Due to their corrosion resistance, duplex stainless steels are widely applied in various industries in which corrosion resistance is a required property. Unlike ferritic and austenitic stainless steels, duplex stainless ...
Resonance switching in a large sonic crystal cavity
(Elsevier, 2017-01)
In this work we present an experimental realization of resonance switching inside a large, relative to the lattice constant, sonic crystal (SC) cavity. The resonances arise from a temporary trapping of the acoustical energy ...
How well do the existing and proposed reserve networks represent vertebrate species in Chile?
(BLACKWELL, 2008-01)
Increasingly, biogeographical knowledge and analysis are playing a fundamental role in assessing the representativeness of biodiversity in protected areas, and in identifying critical areas for conservation. With almost ...
Comparative study of the structural and optical properties of epitaxial CuFeO2 and CuFe(1-x)GaxO(2) delafossite thin films grown by pulsed laser deposition methods
(2017)
Three samples of epitaxial delafossite CuFeO2 and CuFe1-xGaxO2 films were grown using Pulsed Laser Deposition techniques in high vacuum. The sample thicknesses were estimated to be 21 nm, 75 nm for the CuFeO2 films and ...
pH-dependent modulation of voltage gating in connexin45 homotypic and connexin45/connexin43 heterotypic gap junctions
(2010)
Intracellular pH (pH(i)) can change during physiological and pathological conditions causing significant changes of electrical and metabolic cell-cell communication through gap junction (GJ) channels. In HeLa cells expressing ...
A lack of close binaries among hot horizontal branch stars in globular clusters. II. NGC 2808
(2011)
Context. The formation mechanism of hot horizontal branch (HB) stars is still one of the most uncertain points of stellar evolution theories. In the past decade, models based on their binary origin have been very successful ...
O legado no andarilhar de um curso de formação continuada sobre fração
