Poder termoeléctrico del Ce(Pd1-xCux)2Si2Thermoelectric power of Ce(Pd1-xCux)2Si2
(Asociación Física Argentina, 2013-07)
Se presenta un estudio del poder termoeléctrico, S(T), a bajas temperaturas de la aleación Ce(Pd1-xCux )2Si2 . Las curvas de S(T) tienen una dependencia similar en todo el rango de sustitución, con tres anomalías: un máximo ...
The influence of polysaccharide coating on the physicochemical parameters and cytotoxicity of silica nanoparticles for hydrophilic biomolecules delivery
(2019-07-01)
The present work reports the effect of polysaccharides (chitosan and sodium alginate) on silica nanoparticles (SiNP) for hydrophilic molecules delivery taking insulin as model drug. The influence of tetraethyl orthosilicate ...

Structural, chemical and optical characterizations of an experimental SiO2–Y-TZP ceramic produced by the uniaxial/isostatic pressing technique
(2020-06-01)
This study aimed to produce a new SiO2+Y-TZP ceramic via uniaxial/isostatic compression that was structurally and chemically characterized relating to its translucency and flexural strength. SiO2 and Y-TZP were mixed using ...
High-pressure assisted sintering of Ti-20Si-10B and Ti-10Si-5B powders
(2012-11-26)
This work presents the structural characterization of Ti-10Si-5B and Ti-20Si-10B (at-%) alloys produced by high-pressure assisted sintering. Sintering was performed in air at 1100 and 1200°C for 60 s using pressure levels ...
