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.
