(Elsevier France-editions Scientifiques Medicales Elsevier, 2011-09)
Se describe una nueva especie de leguminosa fósil del Neógeno en el noroeste de Argentina. La buena preservación de los tejidos y los caracteres diagnósticos presentes en el leño permitieron su clasificación a nivel ...
Low (and negative) thermal expansion Al2TiO5 materials and Al2TiO5 - 3Al2O3.2SiO2 - ZrTiO4 composite materials. Processing, initial zircon proportion effect, and properties
(Elsevier, 2018-12)
Aluminum titanate (Al2TiO5) materials and aluminum titanate - mullite- zirconium titanate (Al2TiO5 - 3Al2O3.2SiO2 - ZrTiO4) composite materials were successfully processed from fine commercial powders and characterized. ...
Mechanical and thermal shock behavior of refractory materials for glass feeders
(Elsevier Science SA, 2010-06-15)
Refractory materials of the Al2O3–SiO2–ZrO2 system are widely used in glass industry in forehearth, distributors, feeders, and as expendable materials as they are known to have good thermal shock properties. They are ...
Relationship between Formulation, Gelation Kinetics, Micro/Nanostructure and Rheological Properties of Sodium Caseinate Nanoemulsion-Based Acid Gels for Food Applications
(Springer, 2020-02)
Legislation and concerns about health effects of trans and saturated fatty acids have led to elimination or reduction of them in foods formulation. One of the alternatives for structuring food with healthy ingredients is ...
Thermal behavior (TG-DTA-TMA), sintering and properties of a kaolinitic clay from Buenos Aires Province, ArgentinaComportamento térmico (TG-DTA-TMA), sinterização e propriedades de uma argila caulinítica da Província de Buenos Aires, Argentina
(Associação Brasileira de Cerâmica, 2019-06-06)
The technological properties of a local kaolin, considered as a potential industrial material, were correlated with the thermal behavior and sintering processes carried out through a series of thermochemical analyses. The ...
Morpho-structural evaluation of various soils subjected to different use intensity under no-tillage
(Elsevier Science, 2017-06)
According to many evidences, in Argentina, no-tillage (NT) coupled with soybean monoculture leads to adverse soil structure features. While some farmers have simplified the production system through soybean monoculture ...
Phosphorous pentoxide-free bioactive glass exhibits dose-dependent angiogenic and osteogenic capacities which are retained in glass polymeric composite scaffolds
(Royal Society of Chemistry, 2021-12)
Bioactive glasses (BGs) are attractive materials for bone tissue engineering because of their bioactivity and osteoinductivity. In this study, we report the synthesis of a novel phosphorous pentoxide-free, silicate-based ...
