Microstructural characterization and tribological behavior of Laser Furnace processed ceramic tiles
(Elsevier, 2018)
This paper presents, for the first time, the processing of commercial ceramic tiles by means of Laser Furnace (LF) technology and its influence on their microstructure and tribology. Commercial porcelain and white clay, ...

Tailoring Organic-Organic Poly(vinylpyrrolidone) Microparticles and Fibers with Multiwalled Carbon Nanotubes for Reinforced Composites
(American Chemical Society, 2019)
Polymeric-based microparticles and fibers are tailorable for a wide range of common industrial and biomedical applications, while multiwalled carbon nanotubes (MWCNTs) are among the most useful macromolecules based on their ...

Analysis of nanocrystallization kinetics and crystal size distribution under limited growth approach
(Elsevier, 2012)
Two different simulation approaches have been used to describe nanocrystallization processes: a limited growth approach, which is an extension from instantaneous growth approximation, and an average soft impingement ...

Effect of acid-treatment and colloidal-processing conditions on the room temperature mechanical and electrical properties of 3YTZP/MWNT ceramic nanocomposites
(Elsevier, 2017)
Different colloidal powder processing routines have been used to prepare composites of 3 mol% Y2O3 -ZrO2 (tetragonal zirconia polycrystals, 3YTZP) with 2.5 vol% multiwall carbon nanotubes (MWNT) with the aim of achieving ...

High temperature creep of 20 vol%. SiC-HfB2 UHTCs up to 2000 °C and the effect of La2O3 addition
(Elsevier, 2018)
High temperature compressive creep of SiC-HfB2 UHTCs up to 2000 °C has been studied. Microstructural analysis after deformation reveals formation of new phases in the Hf-B-Si and Hf-B-Si-C systems, which are responsible ...

High Temperature Compressive Strength and Creep Behavior of Si-Ti-C-O Fiber-Bonded Ceramics
(Elsevier, 2017)
Fiber bonded silicon carbide ceramic materials provide cost-advantage over traditional ceramic matrix composites and require fewer processing steps. Despite their interest in extreme environment thermostructural applications ...

Los españoles no viven con un jet-lag permanente
(Real Sociedad Española de Física, 2018-12)
La idea de que la hora de Berlín ha perjudicado la vida en España ha hecho fortuna en los últimos años, sin embargo, la comparación correcta de nuestras actividades diarias y las europeas muestra patrones coincidentes

Intragranular carbon nanotubes in alumina-based composites for reinforced ceramics
(Springer Nature, 2019)
The traditional methods for the synthesis of reinforced alumina-based matrix composites with carbon nanotubes (CNTs) have presented serious difficulties for obtaining well-dispersed and homogeneously distributed CNTs within ...

Extension of the Classical Theory of Crystallization to Non-isothermal Regimes: Application to Nanocrystallization Processes
(Elsevier, 2012)
The non-isothermal kinetics of primary crystallization processes is studied from numerically generated curves and their predictions have been tested in several nanocrystallization processes. Single processes and transformations ...

Optometría clínica, desde la práctica hacia la teoría
(Universidad de Sevilla, 2018)
La comunicación se presenta en estas Jornadas Docentes versa sobre la inversión de secuencia de actividades en una clase (flipped Classroom, Flipped Learning o clase invertida) (Barnett & Society for Research into Higher ...
