RESEARCH
TOPICS ( DETAILS ON MY PUBLICATIONS )
Our
group is interested in several problems in materials chemistry and physics,
including data-storage, chemical separation, magnetic resonance imaging,
sintering and pigments. Our approach involves the synthesis of materials that
contain nanoparticulate solid state components, and study of their structure
and properties by a variety of physical techniques.
1)
Nanomagnets for biomedical applications. This project involves
the assembly of nanomagnets into colloidal spherical diamagnetic matrixes. We
have developed methods for growing superparamagnetic nanocrystals with very
exotic magnetic properties both in dense and hollow spherical
matrixes. The surface chemistry of the composites is rationally modified
in order to impart functionality, selectivity and biocompatibility.The final
goal of this work is to obtain ideal superparamagnetic microstructures for
biomedicine and also to gain information on factors controlling the magnetic
response of these materials. For free information on Biomagnetism I recommend you go to
the new open access journal Biomagnetic
Research and Technology
2)
Nanostructured Ceramics.
Another project involves the search of new routes for the preparation of
nanostructured ceramics made of "highly stable" materials. This
project also involves the characterization of the obtained materials as well as
the study of some of their relevant properties.
3)
Data storage. Another area of research involves the synthesis of
magnetic particulate media for recording applications. We have developed
methods to prepare needle-like magnetic metallic particles with applications in
digital recording. Ultimately, the goal is to create materials with high
coercivity and ultrasmall particle size.
