    • As(III) removal from aqueous solution by calcium titanate nanoparticles prepared by the sol gel method 
      Tamayo Calderón, Rocío María; Espinoza González, Rodrigo; Gracia, Francisco; Rodrigues-Filho, Ubirajara Pereira; Flores Carrasco, Marcos; Sacari, Elisban (MDPI AG, 2019)
      Arsenic (As) contamination of water is a serious problem in developing countries. In water streams, arsenic can be as As(V) and As(III), the latter being the most toxic species. In this work, an innovative adsorbent based ...
    • Biological, mechanical and adhesive properties of universal adhesives containing zinc and copper nanoparticles 
      Gutiérrez, Mario F.; Alegría-Acevedo, Luisa F.; Méndez-Bauer, Luján; Bermudez, Jorge; Dávila-Sánchez, Andrés; Buvinic, Sonja; Hernández-Moya, Nadia; Reis, Alessandra; Loguercio, Alessandro D.; Farago, Paulo V.; Martin, Javier; Fernández Godoy, Eduardo (Elsevier Ltd, 2019)
      Objectives: To evaluate the effect of addition of zinc oxide and copper nanoparticles (ZnO/CuNp) into universal adhesives, on antimicrobial activity (AMA), cytotoxicity (CTX), water sorption (WS) and solubility (SO), ...
    • Constraints on the solid solubility of Hg, Tl, and Cd in arsenian pyrite 
      Deditius, Artur P.; Reich Morales, Martín (Mineralogical Society of America, 2016)
      Arsenic-rich (arsenian) pyrite can contain up to tens of thousands of parts per million (ppm) of toxic heavy metals such as Hg, Tl, and Cd, although few data are available on their solid solubility behavior. When a compilation ...
    • Dynamic behavior of sand with Nanoparticles. Comportement dynamique de Sable avec Nanoparticules 
      Ochoa Cornejo, Felipe Agustín (ICSMGE, 2017)
      This work presents an experimental investigation to examine the effect of Laponite-a synthetic nanoclay with high plasticity-on the dynamic behavior of sands. The experimental program considers cyclic triaxial and resonant ...
    • Influence of TiO2 nanostructures on anti-adhesion and photoinduced bactericidal properties of thin film ... 
      García González, Andreina; Quintero, Y.; Vicencio Ovalle, Natalia Fernanda; Rodríguez, B; Ozturk, D.; Mosquera Vargas, Edgar; Corrales, T. P.; Volkmann, U. (Royal Society of Chemistry, 2016)
      This work investigates the influence of TiO2 nanostructures on the anti-adhesion and photoinduced bactericidal properties of thin film composite (TFC) membranes. TiO2 nanostructures with different morphologies, nanoparticle ...
    • Magmatic platinum nanoparticles in metasomatic silicate glasses and sulfides from Patagonian mantle xenoliths 
      González-Jiménez, José María; Roqué-Rosell, Josep; Jiménez-Franco, Abigail; Tassara, Santiago; Nieto, Fernando; Gervilla, Fernando; Baurier, Sandra; Proenza, Joaquín A.; Saunders, Edward; Deditius, Artur P.; Schilling, Manuel E.; Corgne, Alexandre (Springer Verlag, 2019)
      Platinum-rich nanonuggets (s.l., nanoparticles) are commonly produced in experiments attempting to quantify the solubility or partitioning of noble metals in silicate and sulfide melts. However, it has been thought that ...
    • Nanogeochemistry of hydrothermal magnetite 
      Deditius, Artur P.; Reich Morales, Martín; Simon, Adam C.; Suvorova, Alexandra; Knipping, Jaayke; Roberts, Malcolm P.; Rubanov, Sergey; Dodd, Aaron; Saunders, Martin (Springer, 2018-06)
      Magnetite from hydrothermal ore deposits can contain up to tens of thousands of parts per million (ppm) of elements such as Ti, Si, V, Al, Ca, Mg, Na, which tend to either structurally incorporate into growth and sector ...
    • Nanoscale partitioning of Ru, Ir, and Pt in base-metal sulfides from the Caridad chromite deposit, Cuba 
      González Jiménez, José; Deditius, Artur; Gervilla, Fernando; Reich Morales, Martín; Suvorova, Alexandra; Roberts, Malcolm; Roqué, Josep; Proenza, Joaquín A. (Walter de Gruyter GmbH, 2018)
      We report new results of a combined focused ion beam and high-resolution transmission electron microscopy (FIB/HRTEM) investigation of platinum-group elements (PGE)-rich base-metal sulfides. The Ni-Fe-Cu base-metal ...
    • Phytoestrogen coumestrol: Antioxidant capacity and its loading in albumin nanoparticles 
      Montero, Guillermo; Arriagada, Francisco; Günther, Germán; Bollo Dragnic, Soledad; Mura, Francisco; Berríos, Eduardo; Morales, Javier O. (Elsevier B.V., 2019)
      Coumestrol is a polyphenol with promising therapeutic applications as phytoestrogen, antioxidant and potential cancer chemoprevention agent. The presence of two hydroxyl groups on its chemical structure, with orientation ...
    • Size dependent magnetic and capacitive performance of MnFe2O4 magnetic nanoparticles 
      Arun, Thirumurugan; Kumar, T. Kavin; Udayabhaskar, R.; Morel, Mauricio J.; Rajesh, G.; Mangalaraja, R. V.; Akbari Fakhrabadi, Ali (Elsevier, 2020)
      MnFe2O4 magnetic nanoparticles (MNPs) are prepared by simple chemical oxidation method with optimized experimental conditions. The particle size is reduced by introducing the ferric ions as a size reducing agent during the ...
