Balancing porosity and mechanical properties of titanium samples to favor cellular growth against bacteria
(MDPI, 2019)
Two main problems limit the success of titanium implants: bacterial infection, which restricts their osseointegration capacity; and the stiffness mismatch between the implant and the host cortical bone, which promotes bone ...

Theoretical modelling of quaternary GaInAsSb/GaAs self-assembled quantum dots
(Institute of Physics Publishing, 2010)
InAs/GaAs quantum dots exposed to Sb after growth exhibit spectral changes. We study in the present paper an idealized nanostructure consisting of a homogeneous distribution of the quaternary GaInAsSb surrounded by a barrier ...

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 ...

Synthesis and characterization of manganese containing mesoporous bioactive glass nanoparticles for biomedical applications
(Springer, 2018-05)
Mesoporous bioactive glass (BG) nanoparticles based in the system: SiO2–P2O5–CaO–MnO were synthesized via a modified Stöber process at various concentrations of Mn (0–7 mol %). The synthesized manganese-doped BG nanoparticles ...

Atomic scale characterization of SiO2/4H-SiC interfaces in MOSFETs devices
(Elsevier, 2015)
The breakthrough of 4H-SiC MOSFETs is stemmed mainly due to the mobility degradation in their channel in spite of the good physical intrinsic material properties. Here, two different n-channel 4H-SiC MOSFETs are characterized ...

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 ...
