Microstructural Characteristics of Mold Fluxes Associated to their Thermal Behavior
(Elsevier, 2015-07)
During continuous casting process of steels, several problems can arise when an inadequate heat removal in the mold is produced. This heat extraction occurs through mold powder layers formed between the cooled mold and the ...
Thermal parameters changes in males of Rhinella arenarum (Anura:Bufonidae) related to reproductive periods
(Universidad de Costa Rica, 2011)
Boric acid (H3BO3) as flux agent of clay-based ceramics, B2O3 effect in clay thermal behavior and resultant ceramics properties
(Springer, 2019-09)
Ceramic materials were satisfactorily processed through a dry scalable process from binary clay–boric acid (H3BO3) mixtures. Relevant thermal parameters were established by a multitechnique approach that included ...
High-temperature transformations of Zr-pillared bentonite
(Springer, 2020-04-23)
A Zr-modifed bentonite (B-OHZr) obtained by intercalation of OH-Zr species was obtained, and its thermal transformations at >800 °C were studied. Raw clay and B-OHZr were characterized by X-ray difraction, thermogravimetric ...
Coping with temperature extremes: thermal tolerance and behavioral plasticity in desert leaf-cutting ants (Hymeno ptera: Formicidae) across an altitudinal gradient
(Oesterreichische Gesell Entomofaunistik, 2020-06-10)
Current approaches to assess and predict the impact of climate warming on ectotherms are largely based on their physiological sensitivity to temperature. However, these physiological studies provide little insight into the ...
Thermal and surface behavior of yeast protein fractions from Saccharomyces cerevisiae
(Elsevier Science, 2009-07)
An easy and inexpensive method of fractionation of a yeast homogenate was proposed and it is based on differential centrifugation steps of insoluble components and subsequent precipitations of soluble fractions. In this ...
Thermal behavior of samarium oxide – Ball clay mixtures for high macroscopic neutron capture cross section ceramic materials
(Elsevier Science, 2019-02)
The effect of the addition of samarium oxide (Sm2O3) in the thermal behavior of (66%) kaolinitic ball clay was studied and compared with the pure clay. The incorporation of Sm2O3 is of technological interest for the design ...
Effect of montmorillonite on the crystallization and thermal degradation of poly(propylene-coethylene- co-1-butene) nanocomposites
(Sage Publications, 2016-07)
Polymeric nanocomposites based on poly(propylene-co-ethylene-co-1-butene) (PEBC) were elaborated by melt mixing using an organophilic montmorillonite (o-MMT) and maleated PEBC (PEBCg) as compatibilizer. The effect of clay ...
Thermal degradation behavior, permeation properties and impact response of polyethylene/organo-montmorillonite/(ethylene methacrylic acid) ternary nanocomposites
(Vsp Bv, 2009-03)
Through this work we explored the effect of melt compounding a commercial grade of HDPE with organoclays of different precedence using EMAA as compatibilizing agent on the thermal behavior, barrier properties and biaxial ...
