Atomistic modeling of Ag, Au, and Pt nanoframes
(Elsevier Science, 2015-02)
Cubic monoatomic nanoframes of Ag, Au, and Pt were modeled in terms of their evolution with temperature. Using an approximate quantum method for the energetics, Monte Carlo atomistic simulations were performed to determine ...
Effect of glaze cooling rate on mechanical properties of conventional and pressed porcelain on zirconia
(2016-09-01)
The aim of this study was to characterize a conventional and a pressed porcelain for zirconia core as to biaxial flexural strength (BFS), apparent fracture toughness (FT) and microstructure composition, and to investigate ...
Interaction of gramicidin with DPPC/DODAB bilayer fragments
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
The interaction between the antimicrobial peptide gramicidin (Gr) and dipalmitoylphosphatidylcholine (DPPC)/dioctadecyldimethylammonium bromide (DODAB) 1:1 large unilamellar vesicles (LVs) or bilayer fragments (BFs) was ...
The effects of mechanical and hydrothermal aging on microstructure and biaxial flexural strength of an anterior and a posterior monolithic zirconia
(2017-08-01)
Objectives To evaluate the effect of hydrothermal aging (H), mechanical cycling (M), and the combination of hydrothermal plus mechanical cycling (H + M) on biaxial flexural strength (BFS) and microstructure of two monolithic ...
Mechanical Behavior of Ceramic Monolithic Systems With Different Thicknesses
(Operative Dentistry Inc, 2019-09-01)
Objectives: This study assessed the fully stabilized zirconia (FSZ) Prettau Anterior, the partially stabilized zirconia (PSZ) Prettau, and the lithium disilicate IPS e.max CAD (LD) through microstructural and mechanical ...
Resistividade elétrica de concretos com diferentes teores de escória de alto forno e ativador químico
(Universidade Federal de Santa MariaBREngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia Civil, 2005-12-15)
The integrity of the rebars in reinforced concrete structures is related to the chemical and physical protection provided by the concrete layer that covers the steel. The destruction of the passivation layer precedes the ...
