Medium-frequency electrical resistance sintering of oxidized C.P. iron powder
(MDPI, 2018)
Commercially pure (C.P.) iron powders with a deliberate high degree of oxidation were consolidated by medium-frequency electrical resistance sintering (MF-ERS). This is a consolidation technique where pressure, and heat ...

Synthesis and Characterization of Pd over Novel TiO2 Mixtures: Insights on Metal–Support Interactions
(MDPI, 2020)
Palladium nanoparticles were supported on unusual mixtures of anatase, TiO2 (II) and rutile titania phases by wet impregnation, obtaining catalysts with metal contents of ca. 0.25 wt % labeled Pd/Ti5, Pd/Ti45, and Pd/Ti120. ...

Influence of temperature on the biaxial strength of cemented carbides with different microstructures
(Elsevier, 2018)
The effect of the temperature on the mechanical strength of WC-Co cemented carbides with different microstructures (grain size and binder content) was evaluated. Biaxial flexural tests were performed on three cemented ...

A multidisciplinary perspective on the latest trends in artificial cartilage fabrication to mimic real tissue
(Elsevier, 2022-12)
Articular cartilage (AC) has a low ability for endogenous repair, and current treatments are not completely efficient in generating strong and healthy repair tissue. As a result, there is a great deal of interest in ...

Strong activation effect on a ru-co-c thin film catalyst for the hydrolysis of sodium borohydride
(2018)
In this work, we prepared a series of Ni foam supported Ru-Co, Ru-Co-B and Ru-Co-C catalysts in the form of columnar thin films by magnetron sputtering for the hydrolysis of sodium borohydride. We studied the activity and ...

Estimating of bootstrap confidence intervals for freight transport matrices
(Elsevier, 2014)
Freight transport studies require, as a preliminary step, a survey to be conducted on a sample of the universe of agents, vehicles and/or companies of the transportation system. The statistical reliability of the data ...

Synthesis and characterization of in situ-reinforced Al–AlN composites produced by mechanical alloying
(Elsevier, 2017)
This research is focused on the production of aluminum matrix composites (AMCs) reinforced with various percentages of aluminum nitride (AlN). For this purpose, aluminum powder was milled at room temperature for a total ...

Improvement of the balance between a reduced stress shielding and bone ingrowth by bioactive coatings onto porous titanium substrates
(Elsevier, 2018-03)
Commercial pure titanium is known as good substitute for cortical bone tissue. Nevertheless, stress-shielding and the lack of osseointegration are still some limitations to solve. In this study, porous titanium substrates ...

High resolution electron microscopy of GaAs capped GaSb nanostructures
(American Institute of Physics, 2009-01)
We show in this work that GaAs capping of 2 ML of GaSb grown by molecular beam epitaxy results in the formation of very small with heights of about 1 nm GaAsₓxSb₁₋ₓ nanostructures surrounded by a GaAs rich layer. This ...
