Femtosecond Ti: Sa ultra short-pulse laser irradiation effects on the properties and morphology of the zirconia surface after ageing
(2021-02-15)
Femtosecond pulses from a Ti:Sapphire laser were used to irradiate specimens of yttria-stabilised (35% mol) tetragonal zirconia (Y-TZP) with the purpose of studying the effects of the irradiations on their surface properties ...
Air-particle abrasion on zirconia ceramic using different protocols: Effects on biaxial flexural strength after cyclic loading, phase transformation and surface topography
(2013-10-01)
This study evaluated the effect of different air-particle abrasion protocols on the biaxial flexural strength and structural stability of zirconia ceramics. Zirconia ceramic specimens (ISO 6872) (Lava, 3M ESPE) were obtained ...

Seismic retrofit of two-story earthen historic buildings using steel plates
(Universidad de los AndesDoctorado en IngenieríaFacultad de IngenieríaDepartamento de Ingeniería Civil y Ambiental, 2023-06-02)
The Spaniard colonizers of Latin America built constructions using earthen materials, and consequently, adobe and rammed earth became part of the cultural heritage of northern South America. However, these heritage structures ...
