Influence of black shale composition on methane adsorption and gas content: Implications for gas storage in the Longmaxi black shales
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Geociencia, 2018-01-01)
The influence of shale composition on methane adsorption capability and gas content is investigated using 14 samples from Well YS8 in the southern Sichuan Basin, China. The results show that the Langmuir adsorption capacity ...
A quasi-classical evaluation of the J -Shifting approximation for the reactive cross sections of F + CHD 3 and F + CH 4
(American Chemical Society, 2019-07-30)
We evaluated the accuracy of the J-shifting approximation to estimate reactant state-selected cross sections for the F+CH4 → HF+CH3 and F+CHD3 → HF +CD3/DF+CHD2 reactions. In particular, we analyzed how the rotational state ...
Construção, determinação das características ótimas de funcionamento e aplicação de um detector de eletrons de conversão Mossbauer
(Universidade Federal de Minas GeraisUFMG, 1979-12-30)
The use of scattering technique instead of the convencional transmission geometry provides two new resources to Mossbauer Spectroscopy. Firstly, the sample can be studied in its natural form, that is, on does not need ...
Use of diamond-like carbon with tungsten (W-DLC) films as biocompatible material
(ELSEVIER SCIENCE SA, 2008)
Diamond-like carbon (DLC), also known as amorphous hydrogenated carbon (a-C:H), are a class of materials with excellent mechanical, tribological and biological properties. When the DLC films are enhanced with other elements, ...
Catalisadores de Pt suportados, obtidos pelo método solgel : efeito do cério na atividade e estabilidade nas reações de reforma do metano
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2009-12-11)
The effect of Ce as a structural and electronic promoter on the activity and stability of Pt catalysts supported on Al2O3 for methane reforming reactions were investigated to elucidate the metal-support interaction. Pt/Al2O3 ...
The valuable role of renucleation rate in ultrananocrystalline diamond growth
(Elsevier B.V. Sa, 2014)
Síntese e aplicação de nanopartículas de Fe3O4, Fe0 e NiFe2O4 na digestão anaeróbia do glicerol bruto
(Universidade Estadual Paulista (Unesp), 2022-08-09)
O uso de aditivos nanoparticulados nos processos de digestão anaeróbia de resíduos agroindustriais e os efeitos de nanopartículas metálicas em comunidades microbianas e na produção de biogás são temas de grande interesse, ...
Diminished Fluid Transport through Carbon Nanochannels Induced by COOH Functionalization: Implications for Nanofiltration and Oil Recovery
(American Chemical Society, 2021-11)
Fluid transport on confined systems is a subject of theoretical and technological interest. For instance, remarkable high flow rates have been obtained in carbon nanochannels (CNs) which cannot be predicted by standard ...
