Research Areas:

Energy:
Electricity storage in nanostructured carbon
The unique combination of tunable porosity and nanosize crystallinity provides nanostructured carbon with the large surface area and conductivity needed to storage huge amounts of energy when used as a supercapacitor. Exciting results on bench-scale supercapacitor prepared with nanostructurd carbon based supercapacitors encouraged us to move the pilot scale step that we are doing in collaboration with ITE.

Enhaced gasoline production with nanostructured zeolites
Controlled mesoporosity incorporation in type Y zeolites produces a remarkable increase both in conversion and gasoline yield. These materials present enhanced hydrothermal stability due their unique combination of crystallinity and mesoporosity in one single phase. Our patented process does not modify the shape of the original zeolites crystals that expand to accomodate the introduced mesoporosity.

Nanomaterials:
Functionallized metal nanoparticles as surfactants replicas
Metal nanoparticles functionallized with cationic groups have been used as metallic replicas of conventional cationic surfactants (CTAB) used in the production of mesoporous silica. The combination of functionallized metal nanoparticles and CTAB allows for the efficient incorporation of metal nanoparticles in MCM-41

Biomimetics:
Circular mesoporous silica produced with phospholips
The combination of cationic surfactants typically used in the fabrication of mesoporous materials and biomolecules found in cell membranes produces the formation of a novel family of nanostructured materials with circular ordered esoporosity that mimic the structure of certain marine microorganisms

Medice:
Nanostructured titania for more durable orthopedic implants
Nanostructured coatings on metallic orthopedic implants accelerate osteoblast proliferation improving the adhesion between the implant and the bond. Finite element calculations have been used to prove the usefulness of ultrasonic spectroscopy to in-vivo monitor the evolution of the implant in real time.
