    • Copper nanoparticles grown under hydrogen: Study of the surface oxide 
      Díaz Droguett, Donovan Enrique; Espinoza, R.; Fuenzalida, V. M. (Elsevier, 2011)
      Copper nanoparticles with sizes between 10nm and 50nm were grown by condensation in hydrogen at pressures from 10 Pa to 1200 Pa. The crystallite size ranged from 10nm to 25nm using the Scherrer method. X-ray diffraction ...
    • Photoluminescence in silicon/silicon oxide films produced by the Pulsed Electron Beam Ablation technique 
      Araya, M.; Díaz Droguett, Donovan Enrique; Ribeiro, M.; Albertin, K. F.; Avila, J.; Fuenzalida, V. M.; Espinoza, R.; Criado, D. (Elsevier, 2012)
      In this work we report studies of the photoluminescence emission in samples based on Si/SiOx films deposited by the Pulsed Electron Beam Ablation (PEBA) technique. The samples were prepared at room temperature using ...
    • Precipitation kinetics in a 10.5%Cr heat resistant steel: Experimental results and simulation by TC-PRISMA/DICTRA 
      Sanhueza, J. P.; Rojas, D.; Prat, O.; García, J.; Espinoza, R.; Montalba, C.; Melendrez, M. F. (Elsevier, 2017)
      The precipitation kinetics of secondary phases in a 10.5%Cr heat resistant steel, designed by the authors, was studied experimentally and theoretically. Experimental data of nucleation, growth and coarsening stages for ...
    • Valores de referencia del ángulo de balance escapular en población sana 
      Contreras, J.; Gil, D.; Dios Errázuriz, J de; Ruiz, P.; Díaz, C.; Águila, P.; Rosselot, A.; Espinoza, R.; Beltrán, M.; Liendo, R.; Soza, F. (2014)
      Objectives: To calculate the Scapular Balance Angle (SBA) reference values in a healthy population between 18 and 85 years old, and to define abnormality criteria for this sample. Materials and methods: A descriptive study ...
