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 ...
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 ...
Estimations of primary and secondary organic carbon formation in PM2.5 aerosols of Santiago City, Chile
(Elsevier, 2009)
High concentration of fine airborne particulates is considered one of the major environmental pollutants
in Santiago, the Chilean Capital city, which in 1997 was declared a PM10 saturated zone. To date there is
no control ...
Formation and composition of adsorbates on hydrophobic carbon surfaces from aqueous laccase-maltodextrin mixture suspension
(2016-11-01)
A robust procedure for the surface bio-functionalization of carbon surfaces was developed. It consists on the modification of carbon materials in contact with an aqueous suspension of the enzyme laccase from Trametes ...
Steam reforming of ethanol for hydrogen production: Thermodynamic analysis including different carbon deposits representation
(2010)
The importance of H2 production as an energy carrier in the future has driven the attention to reforming systems, such as steam reforming, partial oxidation or oxidative steam reforming of ethanol, considering thermodynamic ...
Early Carboniferous siliciclastic-carbonates in east-central Iran versus coeval carbonates of north Iran: record of latest Tournaisian-early Visean tectonic events
(Instituto de Fisiografía y Geología. Facultad de Ciencias Exactas, Ingeniería y Agrimensura. Universidad Nacional de Rosario, 2016)
Physical and in vitro biological evaluation of a PA 6/MWCNT electrospun composite for biomedical applications

Formation of atomic carbon chains from graphene nanoribbons
(AMER PHYSICAL SOC, 2010)
The formation of one-dimensional carbon chains from graphene nanoribbons is investigated using ab initio molecular dynamics. We show under what conditions it is possible to obtain a linear atomic chain via pulling of the ...
Partial biomimetic reconstitution of avian eggshell formation
(2004)
The avian eggshell is a biocomposite ceramic consisting of minute amounts of organic matrix and a crystalline calcium carbonate (calcite) filler. It is formed by a well regulated spatio-temporal assembling process, where ...
On the 3D void formation of hybrid carbon/glass fiber composite laminates: A statistical approach
(Elsevier B.V., 2020-10-01)
This work aims at assessing the effect of the stacking sequence of hybrid laminates on the 3D void formation through a statistical approach. For that purpose, a three-dimensional microstructure is created from multiple ...
