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 ...
Model for neutron total cross-section at low energies for nuclear grade graphite
(Elsevier Science, 2015-04)
At subthermal neutron energies, polycrystalline graphite shows a large total cross-section due to small angle scattering processes. In this work, a new methodology to determine pore size distributions through the neutron ...
Analysis of porosity, stratigraphy, and structural delineation of a Brazilian carbonate field by machine learning techniques: A case study
(Soc Exploration Geophysicists, 2016-08-01)
The upscaling of well logs has many challenges, especially for carbonate rocks. Primary among them is the suitable choice of seismic attributes to be integrated with well information, whose random combination can produce ...
Estimación de la fragilidad para yacimientos en roca generadora mediante registros de pozo en las formaciones la Luna y Cogollo, Cuenca de Catatumbo, Colombia
(Fundación Universidad de América, 2020-11-05)
La geomecánica es un componente fundamental en el estudio de los yacimientos no convencionales en roca generadora, dado que la producción de este tipo de reservorios depende de la implementación de operaciones de fracturamiento ...
Exploring the Porosity in Ceramics at the nm Scale: From Understanding Historical Ceramics to Innovative Materials Design
(Wiley VCH Verlag, 2020-04)
Ceramics are complex objects and a rich source of information: they constitute a large part of the staple memory of past and present human activities. A deep understanding of traditional ceramics is an essential key to ...

A Gadolinium Metal-Organic Framework Film as a Converter Layer for Neutron Detection
(Wiley VCH Verlag, 2020-10)
Metal-organic frameworks (MOFs) are known for their versatility in terms of their crystalline structure, porosity, resistance to temperature, radiation damage, and luminescence among others. Gadolinium (Gd) is one of the ...
DFA e análise de agrupamento aplicadas a perfis de porosidade neutrônico em poços de petróleo
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciência e Engenharia do PetróleoPesquisa e Desenvolvimento em Ciência e Engenharia de Petróleo, 2009-05-22)
Peng was the first to work with the Technical DFA (Detrended Fluctuation Analysis), a
tool capable of detecting auto-long-range correlation in time series with non-stationary.
In this study, the technique of DFA ...
Thermal behavior of samarium oxide – Ball clay mixtures for high macroscopic neutron capture cross section ceramic materials
(Elsevier Science, 2019-02)
The effect of the addition of samarium oxide (Sm2O3) in the thermal behavior of (66%) kaolinitic ball clay was studied and compared with the pure clay. The incorporation of Sm2O3 is of technological interest for the design ...
