Bacterial behavior on coated porous titanium substrates for biomedical applications
(Elsevier, 2019)
In this work, bacterial behavior on dense and porous titanium substrates is discussed. Porous titanium was fabricated by a space holder technique (using 50 vol%, NH4HCO3 with particle sizes between 250 and 355 μm). These ...

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 ...

Consolidation by MF-ERS of mechanically alloyed Al powder
(Elsevier, 2019-07)
The aim of this work is to study the viability of producing, by medium-frequency electrical resistance sintering (MF-ERS), compacts from mechanically alloyed aluminium powders. The MF-ERS process was carried out using ...

Crystallisation of amorphous Al-Y-Ni-(Cu)alloys
(Elsevier, 2019)
The nanocrystallisation behaviour and subsequent intermetallics formation of an amorphous Al88-Y4-Ni8 alloy has been studied. A 1 at% of Al or Ni was also substituted by Cu and its effect studied. Differential scanning ...

Effect of graphene nanoplatelets thickness on strain sensitivity of nanocomposites: A deeper theoretical to experimental analysis
(Elsevier, 2019-09)
Conductive epoxy nanocomposites were prepared using two different thickness graphene nanoplatelets (GNPs) as reinforcement, H25 and M25. In both cases, 3 and 5 wt % GNPs was dispersed into the matrix by means of sonication ...

Evaluation of sensitivity for detecting different failure modes of epoxy matrix composites doped with graphene nanoparticles
(Elsevier, 2019-10)
In recent years, the interest in monitoring the damage of composite materials by measuring the variation of electrical resistance is increasing because deformations and cracks generated in the structure produce changes in ...

Multibody model of railway vehicles with weakly coupled vertical and lateral dynamics
(Elsevier, 2019-01)
In the field of railroad dynamics, multibody models used for on-board state observation, parameter identification and track geometry measurement must ensure a high computational efficiency, particularly when real-time ...
