Research Overview

Controlling the size and the electronic structure of nanoparticles by inductive heating  synthesis

Colloidal synthesis of nanomaterials is a useful and affordable laboratory process that can be potentially scaled up for industrial production. Controlling the growth of nanoparticles in colloidal solution is an important step towards developing materials with well-defined optical and physical properties. Our research group has successfully developed the Inductive heating method for the synthesis of monodisperse nanomaterials that can potentially broaden the applicability of nanomaterials in practical applications such as in solar cells.

Microporation with magnetic nanoparticles and inhomogeneous pulsed magnetic fields: Rapid drug delivery and cancer treatment

One of the key application areas of nanomaterials is drug delivery and cancer treatment. Magnetic nanomaterials are unique, because with the help of magnetic fields one can reach from our macroscopic world to control processes at the microscopic level. Manipulating small magnetic nanoparticles in solution require either homogeneous or inhomogeneous magnetic fields to move, to rotate or heat these particles. The Chikan group has developed several pulsed magnets that aim to rotate and translate magnetic nanomaterials. We have demonstrated that these magnetic fields will be utilized to achieve instantaneous drug release in magneto liposomes and can be used to enhance drug transport to cancer cells. Our research interest is to explore the fundamental processes need for efficient use of this approach and develop processes that allow successful transformation of a scientific idea to practical applications.

Infrastructure Development at the Extreme Light Infrastructure Attosecond Light Pulse Source(ELI-ALPS)

The main objective of ELI Attosecond Light Pulse Source (ELI-ALPS) is the establishment of a unique laser facility which provides ultrashort light pulses between THz (10¹² Hz) and X-ray (10¹⁸-10¹⁹ Hz) frequency range with high repetition rate for developers and end-users. Our group is exploring formation of diatomic radicals in femtosecond plasmas is important to establish the most dominant kinetic pathways following ionization and dissociation of small molecules. The high repetition rate of the laser allows efficient coupling with the step scan Fourier transform spectroscopy method.  Coulomb explosion at the very high intensity (~10¹⁶ W/cm²) resulted in the formation of nascent atoms, ions and electrons. The condensation reactions of carbon and reactive nitrogen species resulted in the formation of CN(B²Σ⁺) radicals and C₂(d³P_g) dicarbon molecules. The long term of the research is utilize intense terahertz pulses to manipulate chemical reactions and photophysical processes.
