    • A comprehensive study of glucose transfer in the human small intestine using an in vitro intestinal digestion ... 
      Gim-Krumm, Minghai; Donoso, Pablo; Zuñiga, Rommy; Estay, Humberto; Troncoso, Elizabeth (Elsevier B.V., 2018)
      Human digestion is a complex process that involves several phenomena: chemical and enzymatic reactions, absorption, hydrodynamic processes, and mass transfer. The most accurate way to determine the bioavailability of ...
    • Assessment of industrial modules to design a GFMA process for cyanide recovery based on a phenomenological model 
      Estay, Humberto; Troncoso, Elizabeth; Ruby-Figueroa, René; Romero, Julio (MDPI, 2018-04)
      Cyanide recovery in the gold-mining industry is a crucial step in terms of the cost of operation. Currently, a process such as AVR (acidification, volatilization and recycling), based on packed towers for stripping and ...
    • Deconstructing the Leaching Ratio 
      Estay, Humberto; Díaz Quezada, Simón (Springer, 2020)
      The heap leaching process has been widely used for recovering different metals since its first application at the end of the 1960s. In Chile, copper production via heap leaching has accounted for between 30 and 40% of ...
    • Designing the SART process – A review 
      Estay, Humberto (Elsevier, 2018)
      Almost twenty years ago, the first paper about the SART process was published, and eleven years ago the first SART plant was commissioned and operated at Telfer mine, in Australia. Up to this moment, seven SART processes have ...
    • Designing the SART process – A review 
      Estay, Humberto (Elsevier B.V., 2018)
      © 2018 Elsevier B.V. Almost twenty years ago, the first paper about the SART process was published, and eleven years ago the first SART plant was commissioned and operated at Telfer mine, in Australia. Up to this moment, ...
    • Influence of Multidimensional Graphene Oxide (GO) Sheets on Anti-Biofouling and Desalination Performance ... 
      Rodríguez, Bárbara; Armendáriz Ontiveros, María; Hernández Quezada, Rodrigo Alejandro; Huitron Segovia, Esther; Estay, Humberto; García García, Alejandra; García, Andreina (MDPI, 2020)
      The influence of the lateral size and the content of graphene oxide (GO) flakes in specific oxygenate functional groups on the anti-biofouling properties and performance of thin-film composite membrane (TFC) was studied. ...
    • Mo,Cu-doped CeO2 as anode material of solid oxide fuel cells (SOFCs) using syngas as fuel 
      Díaz Aburto, Isaac; Hidalgo, Jacqueline; Fuentes Mendoza, Eliana; González Poggini, Sergio; Estay, Humberto; Colet Lagrille, Melanie (Korean Electrochemistry Society, 2021)
      Mo,Cu-doped CeO2 (CMCuO) nanopowders were synthesized by the nitrate-fuel combustion method aiming to improve the electrical and electrochemical properties of its Mo-doped CeO2 (CMO) parent by the addition of copper. An ...
    • Optimizing the SART process: a critical assessment of its design criteria 
      Estay, Humberto; Gim-Krumm, Minghai; Seriche, Gabriel; Quilaqueo, Michelle; Barros, Lorena; Ruby Figueroa, René; Romero, Julio; Troncoso, Elizabeth (Elsevier, 2020)
      The SART (Sulfidization, Acidification, Recycling and Thickening) process has been successfully installed to recover cyanide and copper in seven worldwide gold cyanidation plants in the last 15 years. This technology has ...
    • Performance evaluation of mass transfer correlations in the GFMA process: a review with perspectives to the design 
      Estay, Humberto; Troncoso, Elizabeth; Ruby Figueroa, Rene; Romero, Julio (Elsevier, 2018)
      Gas filled membrane absorption process (GFMA), or hollow fiber gas membranes process (HFGM) can replace two units operations (absorption and stripping) in a unique stage based on membrane contactors. But its application ...
    • Simulation of Human Small Intestinal Digestion of Starch Using an In Vitro System Based on a Dialysis ... 
      González, Carol; Abarca González, Daniela Alejandra; Zúñiga, Rommy N.; Estay, Humberto; Troncoso, Elizabeth (MDPI, 2020)
      This work deepens our understanding of starch digestion and the consequent absorption of hydrolytic products generated in the human small intestine. Gelatinized starch dispersions were digested with -amylase in an in ...
    • Understanding the phenomenon of copper ions release from copper-modified TFC membranes: A mathematical and ... 
      Quezada, Rodrigo; Quintero Giraldo, Yurieth; Salgado Herrera, José; Estay, Humberto; García, Andreina (MDPI, 2020)
      Type of metal and metal-oxide NPs added to modify Thin-Film Composites Reverse Osmosis Membranes (TFC-RO) can alter their anti-biofouling properties by changing the dissolution process. The development of a mathematical ...
