Structural anomalies for a three dimensional isotropic core-softned potential
(2006) [Artigo de periódico]Using molecular dynamics simulations we investigate the structure of a system of particles interacting through a continuous core-softened interparticle potential. We found for the translational order parameter t a local ... -
The effect of intrinsic soil properties on soil quality assessments
(2013) [Artigo de periódico]The assessment of soil quality is based on indicators and indices derived from soil properties. However, intrinsic soil properties may interfere with other soil properties that vary under different land uses and are used ... -
The electrochemical behavior of brass in 0.1 M HCl solution
(1997) [Artigo de periódico]The electrodissolution of commercial brass (60.8Cu-36.3Zn-2.9Pb) and pure copper in 0.1 M HCl were comparatively studied using cyclic voltammetry and a rotating ring-disk electrode. The dis solution mechanism of both ... -
The electrochemical behavior of iron in acetate solutions containing perchlorate
(1995) [Artigo de periódico]Iron dissolution in acetate media, pH = 5, containing perchlorate in the range of 10ˉ³ M to 0.1 M was studied. Tests on disk and ring disk electrodes using cyclie voltammetry were conducted. The presence of perchlorate ... -
