Kinetics of high-temperature oxidation of (Ti,Ta)(CN)-based cermets
(Elsevier, 2016)
The kinetics of the high-temperature oxidation of titanium–tantalum carbonitride-based cermets with different Ti/Ta ratios was studied. Isothermal oxidation tests were conducted under static air for 48 h at temperatures ...

More Effective Use of Urban Space by Autonomous Double Parking
(Hindawi, 2017-07)
The new capabilities of autonomous cars can be used to mitigate to a large extent safety concerns and nuisance traditionally associated with double parking. In this paper double parking for autonomous cars is proposed as ...

Influence of nano-reinforcements on the mechanical properties and microstructure of titanium matrix composites
(Elsevier, 2011)
The goal of this work is the evaluation of nanoscaled reinforcements; in particular nanodiamonds (NDs) and carbon nanotubes (CNTs) on properties of titanium matrix composites (TiMMCs). By using nano sized materials as ...

An approach using highly sensitive carbon nanotube adhesive films for crack growth detection under flexural load in composite structures
(Elsevier, 2019-09)
Sensing capabilities of carbon nanotube (CNT)doped adhesive films under bending conditions were investigated. Standard Mode-II coupons and skin-stringer sub-elements were manufactured while their electrical resistance was ...

Designing bioactive porous titanium interfaces to balance mechanical properties and in vitro cells behavior towards increased osseointegration
(Elsevier, 2019)
Titanium implant failures are mainly related to stress shielding phenomenon and the poor cell interaction with host bone tissue. The development of bioactive and biomimetic Ti scaffolds for bone regeneration remains a ...

Influence of Milling Atmosphere on the Controlled Formation of Ultrafine Dispersoids in Al-Based MMCs
(MDPI, 2016)
Properties of compacts made from aluminium powder, milled under different atmospheres, were evaluated. The duration of all the milling processes was 10 h, although different atmospheres were tested: vacuum, confined ...

Supervised Land Use Inference from Mobility Patterns
(Hindawi Limited, 2018)
This paper addresses the relationship between land use and mobility patterns. Since each particular zone directly feeds the global mobility once acting as origin of trips and others as destination, both roles are simultaneously ...

Structural and optical changes induced by incorporation of antimony into InAs/GaAs(001) quantum dots
(American Physical Society, 2010)
We present experimental evidence of Sb incorporation inside InAs/GaAs 001 quantum dots exposed to an antimony flux immediately before capping with GaAs. The Sb composition profile inside the nanostructures as measured by ...

Surface modification of Ti-6Al-4V alloys manufactured by selective laser melting: Microstructural and tribo-mechanical characterization
(Elsevier, 2018)
Medical grade of both titanium (Ti) and Ti6Al4V alloy are recognized as the metallic biomaterials with the better outcomes for clinical repair of bone tissue thanks to their suitable mechanical properties and corrosion ...

Influence of sintering temperature on the microstructure and mechanical properties of in situ reinforced titanium composites by inductive hot pressing
(MDPI AG, 2016-11)
This research is focused on the influence of processing temperature on titanium matrix composites reinforced through Ti, Al, and B4C reactions. In order to investigate the effect of Ti-Al based intermetallic compounds on ...
