Depositional, diagenetic and stratigraphic aspects of Macaé Group carbonates (Albian): Example from an oilfield from Campos Basin
(2015-01-01)
Carbonate rocks from the Macaé Group (Albian) represent an example of carbonate sedimentation related to the drift phase in Campos Basin. This study presents depositional features, integrating them with diagenetic and ...
NITRORADICAL ANION FORMATION FROM NITROFURANTOIN IN CARBON ELECTRODES
(Sociedad Chilena de Química, 2000)
Synthetically useful carbon-carbon and carbon-sulphur bond constructions mediated by carbon- and sulphur-centred radicals in water and aqueous media
(Royal Society of Chemistry, 2011-07)
This account is focused on carbon-carbon, and carbon-sulphur bond-forming reactions through the use of carbon- and sulphur-centred radicals in water, respectively. It intends to show the scope and applications on these ...
Selectivity of the cyclic carbonate formation by fixation of carbon dioxide into epoxides catalyzed by Lewis bases
(Pergamon-Elsevier B.V. Ltd, 2008-11-24)
Cyclic carbonate and polycarbonate have been selectively obtained with good conversion by coupling carbon dioxide with diglycidylether of bisphenol A. The ruthenium trichloride supported on tetraethylammonium bromide and ...

Improved activity and stability of Ce-promoted Ni/γ-A1 2O3 catalysts for carbon dioxide reforming of methane
(2004-07-01)
The CO2 reforming of CH4 was carried out over Ni catalysts supported on γ-Al2O3 and CeO 2-promoted γ-Al2O3. The catalysts were characterized by means of surface area measurements, TPR, CO2 and H2 chemisorption, XRD, SEM, ...

Films formed on carbon steel in sweet environments - A review
(2019-01-01)
Corrosion of carbon steel pipelines in sweet environments has been extensively researched on oil and natural gas exploration and production in order to obtain efficient corrosion mitigation methods. Although the consequences ...
Paired isotope records of carbonate and organic matter from the Middle Ordovician of Argentina: Intrabasinal variation and effects of the marine chemocline
(Elsevier Science, 2017-10)
We investigate the expression of the Middle Darriwilian isotope carbon excursion (MDICE) across marine shelf environments in the Argentine Precordillera. Previous work identified the MDICE in the Las Chacritas Formation ...
