Pt-Ru-supported electrodes deposited by multiple successive cycles of potentiostatic pulses: Evaluation of Nafion film effect on methanol oxidation
(Springer, 2010-09-16)
The influence of thin Nafion films on electro-deposited Pt-Ru electrocatalysts for the electro-oxidation of methanol was studied. Nanostructured planar carbon-supported Pt-Ru electrodes, on which a layer of Nafion ionomer ...
Wood technology: production sequences and use of Woody raw materials among hunter-gatherer patagonian groups (Argentina)
(Taylor & Francis Ltd, 2021-04-16)
The objective of this work is to reconstruct production sequences and use of woody raw materials among Patagonian hunter-gatherer groups. To this end, we studied small fragments of non-carbonized wood, pieces of wood with ...
Characterization of chimeric ADPglucose pyrophosphorylases of Escherichia coli and Agrobacterium tumefaciens. Importance of the C-terminus on the selectivity for allosteric regulators
(American Chemical Society, 2002-07)
ADPglucose pyrophosphorylase catalyzes the regulatory step in the pathway for bacterial glycogen synthesis. The enzymes from different organisms exhibit distinctive regulatory properties related to the main carbon metabolic ...
Orbital controls and high-resolution cyclostratigraphy of Late Jurassic Early-Cretaceous in the Neuquén Basin
(Springer, 2020)
Detailed cyclostratigraphic analyses have been made from seven Tithonian–Hauterivian sections of the Vaca Muerta and Agrio Formations, exposed in southern Mendoza area of the Neuquén Basin. Both lithostratigraphic units ...
Characterization of starch and composite edible films and coatings
(Springer, 2009)
Starch-based and composite edible films and coatings can enhance food quality, safety and stability. They can control mass transfer between components within a product, as well as between product and environment. They can ...
Raman spectroscopy in experimental rock art: Improving the study of ancient paintings
(John Wiley & Sons Ltd, 2020-11)
The present work analyzes Raman spectra of red, white, and black experimental paintings manufactured according to archeological and ethnographical data from Patagonia (South America), in order to provide reference patterns ...
Mechanical behaviour of cementitious composites reinforced with bagasse and hemp fibers
(Elsevier, 2019-12)
Vegetable fibers are increasingly used in composites because of their good mechanical properties and low carbon footprint; composites made with vegetable fibers are considered greener and have mechanical and thermal ...
A pattern recognition system based on acoustic signals for fault detection on composite materials
(Gauthier-Villars/Editions Elsevier, 2016-12)
The use of composite materials in industry applications is constantly growing. However, fault detection and prediction on these materials is not as simple as in traditional materials. Thus, the development of a methodology ...
Products and Mechanism of the Reactions of OH Radicals and Cl Atoms with Methyl Methacrylate (CH2═C(CH3)C(O)OCH3) in the Presence of NOx
(American Chemical Society, 2014-01)
The OH radical and Cl atom initiated photodegradation of methyl methacrylate has been investigated in a 1080 L quartz-glass environmental chamber at 298 ± 2 K and atmospheric pressure of synthetic air using in situ FTIR ...
Perception of Sunflecks by the UV-B Photoreceptor UV RESISTANCE LOCUS8
(American Society of Plant Biologist, 2018-03)
Sunflecks, transient patches of light that penetrate through gaps in the canopy and transiently interrupt shade, are eco-physiologically and agriculturally important sources of energy for carbon gain, but our molecular ...
