Patterns and origins of the porosity in the productive reservoirs of the upper part of the Chubut Group, southern flank of the Golfo de San Jorge Basin, Patagonia Argentina
(Pergamon-Elsevier Science Ltd, 2020-05)
The Mina del Carmen, Bajo Barreal and Cañadón Seco Formations bear the most important Cretaceous reservoirs in the southern flank of the Golfo de San Jorge Basin, in which the porosity is mainly secondary in origin. Primary ...
Porosity and permeability in volcanic rocks: A case study on the Serie Tobífera, South Patagonia, Argentina
(Elsevier Science, 2004-04)
The Middle to Late Jurassic Serie Tobífera belongs to the Chon-Aike Province and extends all over Patagonia and the Antarctic Peninsula. It consists largely of ignimbrites, epiclastics and rhyolitic lavas and was considered ...
Porosity effects on the neutron total cross section of graphite
(Elsevier Science, 2010-01)
For subthermal neutron energies, polycrystalline graphite shows a larger total cross section than predicted by existing theoretical models. In order to investigate the origin of this discrepancy we measured the total cross ...
Influence of microstructure on the corrosion behavior of nitrocarburized AISI H13 tool steel obtained by pulsed DC plasma
(Elsevier Science Sa, 2009-02)
The influence of microstructure on the corrosion behavior of pulsed plasma nitrocarburized AISI H13 tool steel in NaCl 0.9 wt/V % solution is reported. The samples were prepared with different nitrocarburizing treatment ...
Growth of ZIF-8 MOF films with tunable porosity by using poly (1-vinylimidazole) brushes as 3D primers
(Wiley VCH Verlag, 2020-09-25)
This work reports on a novel and versatile approach to control the structure of metal–organic framework (MOFs) films by using polymeric brushes as 3D primers, suitable for triggering heterogeneous MOF nucleation. As a ...
Soil porosity characteristics and water movement under zero tillage in silty soils in Argentinian Pampas
(Elsevier, 2006-05)
The objective of this study was to identify pore characteristics (quantity, distribution, stability and orientation of pores) that condition water dynamics under continuous zero tillage (ZT) on silty soils of the Argentinian ...
