Ichnology and Sedimentology of Estuarine deposits from Mata Amarilla Formation, Austral Basin, Argentina
(Sociedad Española de Paleontología, 2014-02)
The Mata Amarilla Formation is part of the infilling of the Austral Basin, located in Southern Patagonia, Argentina. This unit is mainly composed of grey to black mudstones interbedded with white fine- to coarse-grained ...
On the reproducibility of spray-coated ZnO thin-film transistors
(Cambridge Univ Press, 2020-01-01)
Recent studies have shown spray-pyrolysis is a low-cost, simple and efficient technique for deposition of metal oxide semiconductors (such as zinc oxide) as the active layer of thin-film transistors (TFTs). However, to ...
Silicon nitride thin films deposited by electron cyclotron resonance plasma enhanced chemical vapor deposition for micromechanical system applications
(Elsevier Science SaLausanneSuíça, 2008)
Heterogeneous distribution of trace fossils across initial transgressive deposits in rift basins: an example from the Springhill Formation, Argentina
(Wiley Blackwell Publishing, Inc, 2016-10)
In the Lago San Martín region (Santa Cruz Province, Argentina), the Springhill Formation (50–100 m thick) overlies the syn-rift El Quemado Complex, showing outcrops with wedge geometry. Four sedimentological sections were ...
Selective Inhibition of Paraffin Deposition under High Flow Rate as a Function of the Crude Oil Paraffin Type and Content by Fluorescence Depolarization: Polypropylene and High-Density Polyethylene
(2006)
High-density polyethylene (HDPE) and polypropylene (PP) were studied to identify tailor-made materials for walls of pipelines and ducts for crude paraffinic oil that inhibit paraffin depositions. The interfacial
interaction ...
High density flux of Co nanoparticles produced by a simple gas aggregation apparatus
(AMER INST PHYSICS, 2010)
Gas aggregation is a well known method used to produce clusters of different materials with good size control, reduced dispersion, and precise stoichiometry. The cost of these systems is relatively high and they are generally ...
Interannual variability of estimated monthly nitrogen deposition to coastal waters due to variations of atmospheric variables model input
(Elsevier Science Inc, 2010-04)
In this work, the influence of the interannual variation of meteorological input data on the nitrogen (N) deposition estimated applying atmospheric dispersion models is discussed. As a case study, the deposition of atmospheric ...
Estratigrafia de sequências do intervalo aptiano ao albiano na Bacia do Araripe, NE do Brasil
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Geodinâmica e GeofísicaGeodinâmica; Geofísica, 2009-02-27)
This study has as a main objective to make a detailed stratigraphic analysis of the Aptian-Albian interval in the east part of Araripe Basin, NE of Brazil which correspond,
litostratigraphically, to Rio Da Batateira, ...
Formation, antimicrobial activity, and controlled release from cotton fibers with deposited functional polymers
(Wiley, 2016)
Chitosan and alginate are biopolymers with interesting bioactivity that can be transferred to cotton fibers for medical and health care applications. These polymers in solution can be attached onto cotton fibers by a ...
