    • A new isomer of C 20 and a way to a new C 240 
      Cárdenas, Carlos; Muñoz, Francisco; Muñoz, Macarena; Bernardin, Alejandro; Fuentealba Rosas, Patricio (2012)
      Here we show that the dynamic simulation of a molecular collision can give insight into new molecular species. In this way, a new stable isomer of C 20 (IV) has been found. It is planar with pentagonal form. This isomer ...
    • How predictive could alchemical derivatives be? 
      Muñoz, Macarena; Cárdenas Valencia, Carlos (Royal Society Chemistry, 2017)
      The chemical space contains all possible compounds that can be imagined. Its size easily equals the number of fundamental particles in the observable universe. Rational design of compounds aims to find those sectors of the ...
    • Performance of modified Lennard-Jones potential to seed ab initio calculations of small cadmium clusters 
      Muñoz, Macarena; Varas, Alejandro; Cárdenas, Carlos; Rogan Castillo, José; Fuentealba Rosas, Patricio (2013)
      Weakly bonded Cadmium clusters have, even for small number of atoms, many isomers that are stable structures. Before any attempt to use ab initio calculations on these clusters, a limited set of good possible stable isomers ...
    • Predicting deprotonation sites using alchemical derivatives 
      Muñoz, Macarena; Robles Navarro, Andrés; Fuentealba Rosas, Patricio; Cárdenas Valencia, Carlos (American Chemical Society, 2020)
      An alchemical transformation is any process, physical or fictitious, that connects two points in the chemical space. A particularly important transformation is the vanishing of a proton, whose energy can be linked to the ...
    • Primary angioplasty for acute myocardial infarction with an anomalous origin of right coronary artery. ... 
      Ugalde Prieto, Héctor; Muñoz, Macarena; Ugalde, Diego; García, Sebastián (2012)
      Anomalous origin of coronary arteries is a rare anatomical defect and its association with acute myocardial infarction is unusual. We report a 58-year-old male with ST-Segment elevation. Myocardial infarction of the inferior ...
    • Sub capsular splenic hematoma in a sickle cell trait carrier. case report Hematoma subcapsular esplénico ... 
      Ugalde, Diego; Conte, Guillermo; Ugalde, Héctor; Figueroa, Gastón; Cuneo, Marianela; Muñoz, Macarena; Mayor, Javiera (2011)
      Drepanocytic anemia is an uncommon hereditary disease in Chile. The heterozygous state of drepanocytic anemia or "sickle trait" has a frequency of 8% among Afro-Americans. A small number of patients carrying hemoglobin S ...
    • Terapia de reperfusión en infarto agudo al miocardio. Comparación entre trombolisis endovenosa y ... 
      Ugalde, Héctor; Ugalde, Diego; Muñoz, Macarena (2011)
      Background: Primary angioplasty is superior to intravenous thrombolysis as reperfusion therapy for acute myocardial infarction. Aim: To compare the results of available reperfusion strategies for initial management of ...
    • Understanding chemical reactivity in extended systems: exploring models of chemical softness in carbon nanotubes 
      Cárdenas Valencia, Carlos; Muñoz, Macarena; Contreras, Julia; Ayers, Paul W.; Gomez, Tatiana; Fuentealba Rosas, Patricio (Peking University Press, 2018)
      Chemical reactivity towards electron transfer is captured by the Fukui function. However, this is not well defined when the system or its ions have degenerate or pseudo-degenerate ground states. In such a case, the first-order ...
