Research Interests
We have research interest in polynuclear compounds of
lanthanide(III), p- and d-block ions with potential biomedical, extractive
metallurgical and catalytic applications. Their preparation, structures and
luminescence spectroscopy and decay dynamics as well as electron paramagnetic
resonance behavior are the main focus. Lasers ( 1J YAG and 1 mJ nitrogen and
their matching dye lasers) along with a helium refrigerator, luminescence
spectrometer and accompanying electronics are the major instrumentation. Ligands
of interest are aromatic Schiff's bases, crown ethers, phthalamates and
alkylamine dendrimers and their derivatives.
We also have interests in solid waste and environmental
pollution, especially asbestos waste. Waste disposal, polluted sites, their
public health effects and policy issues are of interest.
