STUDY MINERAL COLUMBITE- TANTALITE WITH METALLURGICAL APPROACH TO DEFINE THE USE OF SAND DEPOSITS WITH HEAVY MINERALS

open access: yesAvances en Ciencias e Ingeniería, 2016
The aim of this work was to study a sample of sand from a site of Bolivia, in order to obtain a pre-concentrate high grade Nb-Ta. Particle size analysis was performed and quantified in each class the chemical composition of Nb and Ta.

Three-Dimensional Interaction of Viscous Fingering and Gravitational Segregation in Porous Media

open access: yesFluids, 2019
Viscous fingering is fluid dynamics instability induced on the displacement front when a less viscous fluid (LVF) displaces a more viscous fluid (MVF), thereby reducing the displacement efficiency. The displacement of a denser fluid by a less dense fluid

Packed Hydrogel Microfibers as Scaffolds Supporting Dynamic Cellular Behavior and Biomaterial Inks in 3D Printing

open access: yesAdvanced Healthcare Materials, EarlyView.
Packed hydrogel microfiber (PHM) materials consist of flexible and high aspect ratio hydrogel components that, as a bulk material, are simultaneously mechanically robust and dynamic. Cells cultured in or on PHM scaffolds can be influenced by topographical cues or interact with a dynamic environment that permits cell spreading and multicellular ...

Multidimensional Cellular Micro‐Compartments to Model Invasive Lobular Carcinoma Dormancy

open access: yesAdvanced Healthcare Materials, EarlyView.
Invasive lobular carcinoma (ILC) is an understudied subtype of breast cancer that is susceptible to late recurrences. In this study, micro‐compartmentalization techniques spanning multiple dimensions, including 2D, pseudo‐3D, and 3D, are integrated to uncover the mechanisms underlying ILC dormancy, revealing the central role of p27Kip1.
