Microestructura y propiedades de compuestos de Fe3O4/BaTiO3/epoxi [PDF]

open access: yesRevista Materia, 2010
Con el objetivo de estudiar nuevos materiales multipropósito, en este trabajo se analizó la influencia de las partículas de Fe3O4 y BaTiO3 sobre las propiedades magnéticas y dieléctricas de los sistemas Fe3O4/BaTiO3/epoxi. A tal efecto se analizaron los sistemas bifásicos Fe3O4/epoxi y BaTiO3/epoxi y a partir del análisis de los resultados se ...

Superbainita. Una nueva microestructura bainítica de alta resistencia Superbainite

open access: yesRevista De Metalurgia, 2005
En este trabajo se muestran los resultados de investigaciones muy recientes que revelan la posibilidad de obtener bainita por transformación isotérmica a temperaturas muy bajas, del orden de 150 °C, en aceros de alto carbono y silicio. La microestructura así obtenida no tiene cementita y está formada por placas de ferrita bainítica extremadamente finas

Improving Pea Protein Emulsifying Capacity by Glycosylation to Prepare High-Internal-Phase Emulsions

open access: yesFoods, 2023
Pea protein has been extensively studied because of its high nutritional value, low allergenicity, environmental sustainability, and low cost. However, the use of pea protein in some food products is hindered due to the low functionality of pea protein ...

3D pollination biology using micro‐computed tomography and geometric morphometrics in Theobroma cacao

open access: yesApplications in Plant Sciences, Volume 11, Issue 5, September-October 2023., 2023
Abstract Premise Imaging technologies that capture three‐dimensional (3D) variation in floral morphology at micro‐ and nano‐resolutions are increasingly accessible. In herkogamous flowers, such as those of Theobroma cacao, structural barriers between anthers and stigmas represent bottlenecks that restrict pollinator size and access to reproductive ...

Exploiting Light Directionality for Image‐Based 3D Reconstruction of Non‐Collaborative Surfaces

open access: yesThe Photogrammetric Record, Volume 37, Issue 177, Page 111-138, March 2022., 2022
The paper investigates the effect of light directionality and the fusion of multiple images to improve the quality of photogrammetric 3D reconstruction of complex surfaces (textureless and shiny). We present an image capturing system that utilizes multiple light sources to highlight roughness which is not visible in traditional diffuse images ...

Agave Syrup as an Alternative to Sucrose in Muffins: Impacts on Rheological, Microstructural, Physical, and Sensorial Properties

open access: yesFoods, 2020
Natural sweeteners, such as agave syrup, might be a healthy alternative to sucrose used in sweet bakery products linked to obesity. We evaluated the effect of sucrose replacement by agave syrup on rheological and microstructural properties of muffin ...

Improving Microwave Heating using Polysaccharides as Thickeners

open access: yesCzech Journal of Food Sciences, 2009
The aim of this work was to improve microwave heating in white sauces using different polysaccharides in their formulation; ι-, λ- and κ-carrageenan and native and modified starches were used as thickeners. Five model systems were prepared, each one with

Chemical and Structural Changes in White Sauces Thawed by Microwave or Conventional Oven

open access: yesCzech Journal of Food Sciences, 2009
Proteins, lipids and structural changes in white sauces after being stored at -18°C and thawed by microwave and conventional oven were studied in this work. The total crude and soluble protein fractions were quantified by N-Kjeldahl.

Effect of Pulsed Electric Fields on the Main Chemical Components of Liquid Egg and Stability at 4°C

open access: yesCzech Journal of Food Sciences, 2009
The effect of PEF on the whole liquid egg components, proteins and lipids, and the microstructure were studied and compared with pasteurisation. The effect of the refrigerated storage one week after the treatments was too studied.

Austenización de aceros con microestructuras diferentes

open access: yesRevista de Metalurgia, 2004
Durante los últimos años se han desarrollado algunos modelos físico-matemáticos sobre las transformaciones de fase en enfriamiento continuo e isotérmicas, aplicables a un amplio rango de aceros. Sin embargo, la modelización de las transformaciones en calentamiento continuo no ha tenido un desarrollo paralelo a las de enfriamiento y su avance ha sido ...
