Dr. Ebner’s major research
interest is the application of magnetic fields to the separation,
collection and/or manipulation of magnetic particles from a fluid
medium, with particular emphasis in the use of high gradient magnetic
separation (HGMS) principles. This technique consists on the use of
fine ferromagnetic elements that as a result of the application of an
external magnetic field become energized and create magnetic gradients
large enough to collect particles that because of their small size
and/or low magnetism their collection cannot be otherwise realized.
Today major emphasis and potential for HGMS is found in the medical
area where the technique can be used to assist magnetic drug targeting
for cancer treatment, restenosis, embolization control as well as for
rapid detoxification.
Other research interests of
Dr. Ebner are the development and understanding of complex hydrides
for hydrogen storage and the development of new process designs (i.e,
PSA and TSA) for gas separation processes. In terms of complex
hydrides, major efforts are currently devoted to understanding the
mechanistic role of catalysts such as Ti, Zr, V as well as that of
co-dopants such as Fe, Ni and others in the observed enhanced kinetics
of dehydrogenation and hydrogen regeneration of alanates. In terms of
gas separation processes, efforts are concerted into CO2 removal for
spatial air revitalization (NASA) and CO2 sequestration from flue-gas
(EPA) using high temperature adsorbents (e.g., hydrotalcites).
