    • Body mass, phylogeny and diet composition affects kidney morphology in passerine birds 
      Barceló Carvajal, Gonzalo; Salinas Castillo, Jonathan; Sabat Kirkwood, Alejandro Pablo (2012)
      We studied the renal morphology of 16 species of passerines to assess whether the composition of the diet of birds have been paralleled by differences in the characteristics of the kidneys. We determined the number and ...
    • Designing boron and metal complexes for fluoride recognition: a computational perspective 
      Pereira Orenha, Renato; Peixoto, Leticia Bermudes; Caramori, Giovanni Finoto; Piotrowski, Mauricio Jeomar; Araujo Batista, Krys Elly de; Contreras García, Julia; Cárdenas Valencia, Carlos Alberto; Morgon, Nelson Henrique; Mendizábal Emaldia, Fernando Javier; Tame Parreira, Renato Luis (Royal Soc. Chemistry, 2021)
      Fluoride anions (F-) may have beneficial or harmful effects on the environment depending on their concentration. Here, we shed light on F- recognition by compounds containing boron, tellurium and antimony, which were ...
    • Geographical origin determines responses to salinity of Mediterranean caddisflies 
      Carter, Mauricio J.; Flores González, Matías; Ramos Jiliberto, Rodrigo (Public Library Science, 2020)
      Many freshwater ecosystems worldwide, and particularly Mediterranean ones, show increasing levels of salinity. These changes in water conditions could affect abundance and distribution of inhabiting species as well as the ...
    • Rotating disk sorptive extraction of cu-bisdiethyldithiocarbamate complex from water and its application ... 
      Muñoz, Carlos; Toral Ponce, María; Ahumada, Inés; Richter Duk, Pablo (Japan Society for Analytical Chemistry, 2014)
      This study demonstrates the first use of polydimethylsiloxane (PDMS) immobilized on a rotating disk for the extraction of copper from aqueous matrices and its subsequent direct determination by solid phase UV-Visible ...
    • Solvent effect on a model S N Ar reaction in ionic liquid/water mixtures at different compositions 
      Sánchez, Bruno; Calderón, Cristian; Garrido, Constanza; Contreras Ramos, Renato; Campodonico, Paola R. (The Royal Society of Chemistry, 2018)
      The reaction of phenyl 2,4,6-trinitrophenyl ether and piperidine was kinetically evaluated in BMIMBF4/water mixtures as the reaction media. This study shows the dramatic effect of the mixture composition on the reacting ...
