Novel aspects of parenchymal–mesenchymal interactions: from cell types to molecules and beyond
(Wiley, 2013-06)
Mesenchymal stem or stromal cells (MSCs) were initially isolated from the bone marrow and received their name on the basis of their ability to differentiate into multiple lineages such as bone, cartilage, fat and muscle. ...
Taking advantage of contextualized interactions while users watch TV
(SPRINGER, 2010)
While watching TV, viewers use the remote control to turn the TV set on and off, change channel and volume, to adjust the image and audio settings, etc. Worldwide, research institutes collect information about audience ...
The Interactive Holography as Metaphor and Innovation in Optical Representation in Design
(2015-01-01)
The strong technological development in the use of virtual images has allowed science, associated with design, to integrate them to different applications in the physical field, interacting with the real world, proposing ...
Steam-methane reforming at low temperature on nickel-based catalysts
(Elsevier, 2013-09)
In this work, we report the activity results obtained in steam-methane reforming (SMR) at 500 and 600 °C using four nickel-based catalysts: (a) Ni/Al2O3 and Ni/SiO2, prepared by incipient wetness impregnation method and ...
Symmetry‐Breaking Charge‐Transfer Chromophore Interactions Supported by Carbon Nanodots
(Wiley VCH Verlag, 2020-05)
Carbon dots (CDs) and their derivatives are useful platforms for studying electron-donor/acceptor interactions and dynamics therein. Herein, we couple amorphous CDs with phthalocyanines (Pcs) that act as electron donors ...
Soot combustion. Co and K catalysts supported on different supports
(Springer, 2002-01)
The catalytic combustion of particulate material was studied on cobalt catalysts promoted with potassium using different supports for its preparation. Silica, aluminum oxides and hydroxides, zirconium oxide and hydroxide ...
Supporting clinical information management by NFC technology
(2009-07-01)
Tele-monitorization is a problem with aging people living alone since the vital signs control is complicated for them. In this sense, some initiatives by adapting technologies make easy these controls. In this work we ...
Characterizing acceptability semantics of argumentation frameworks with recursive attack and support relations
(Elsevier Science, 2018-09)
Over the last decade, several extensions of Dung's Abstract Argumentation Frameworks (AFs) have been introduced in the literature. Some of these extensions concern the nature of the attack relation, such as the consideration ...
The electro-oxidation of carbon monoxide and ethanol on supported Pt nanoparticles: The influence of the support and catalyst microstructure
(2013-07-01)
The sluggish kinetics of ethanol oxidation on Pt-based electrodes is one of the major drawbacks to its use as a liquid fuel in direct ethanol fuel cells, and considerable efforts have been made to improve the reaction ...
