Assessing the Biofortification of Wheat Plants by Combining a Plant Growth-Promoting Rhizobacterium (PGPR) and Polymeric Fe-Nanoparticles: Allies or Enemies?
(MDPI, 2022-01)
Biofortification has been widely used to increase mineral nutrients in staple foods, such as wheat (Triticum aestivum). In this study, a new approach has been used by analyzing the effect of inoculation with a plant ...

Characterization and Monitoring of Titanium Bone Implants with Impedance Spectroscopy
(MDPI, 2020-08)
Porous titanium is a metallic biomaterial with good properties for the clinical repair of cortical bone tissue, although the presence of pores can compromise its mechanical behavior and clinical use. It is therefore necessary ...

Diseño, procesado y caracterización, procesado y caracterización de materiales con porosidad radial controlada para aplicaciones nucleares
(Grupo Español de Fractura, 2015)
Las pastillas de combustible irradiado presentan un gradiente de porosidad radial como consecuencia de la presencia de gas He y otros productos de fisión que modifican su microestructura. El óxido de Cerio, CeO2, ha ...

Nanotextured porous titanium scaffolds by argon ion irradiation: Toward conformal nanopatterning and improved implant osseointegration
(Wiley, 2023-06)
Stress shielding and osseointegration are two main challenges in bone regeneration, which have been targeted successfully by chemical and physical surface modification methods. Direct irradiation synthesis (DIS) is an ...

Tribo-mechanical and cellular behavior of superficially modified porous titanium samples using femtosecond laser
(Elsevier, 2021-09)
In this work, the surface of porous titanium samples obtained by the space-holder technique was treated with a femtosecond laser to improve their osseointegration. Instrumented micro-indentation and scratch test were ...

Biofunctional and Tribo-mechanical Behavior of Porous Titanium Substrates Coated with a Bioactive Glass Bilayer (45S5 ‒ 1393)
(American Chemical Society, 2020-06)
Porous substrates of commercially pure titanium have been coated with a novel bilayer of bioactive glasses, 45S5 and 1393, to improve the osseointegration and solve the stress-shielding phenomenon of titanium partial ...

Porous Titanium for Biomedical Applications: Evaluation of the Conventional Powder Metallurgy Frontier and Space-Holder Technique
(MDPI, 2019)
Titanium and its alloys are reference materials in biomedical applications because of their desirable properties. However, one of the most important concerns in long-term prostheses is bone resorption as a result of the ...

Effect of sintering time on the microstructure and mechanical properties of (Ti,Ta)(C,N)-based cermets
(Elsevier, 2013)
Complete solid-solution cermets based on titanium-tantalum carbonitride using a starting nominal composition with 80 wt.% of (Ti0.8Ta 0.2)(C0.5N0.5) and 20 wt.% of Co were performed by pressure-less sintering at 1550 C for ...

Bioactive Coatings on Porous Titanium for Biomedical Applications
(Elsevier, 2018)
Commercial pure titanium is a recognized and accepted material for cortical bone tissue substitution. However, stress-shielding phenomena and lack of osseointegration result in significant limitations. This work is focused ...
