21. Biomolecular Recognition Based on Field Induced Magnetic Bead Dynamics
Abstract : In this thesis, three different read-out techniques for biomolecular recognition have been studied. All three techniques rely on the change in dynamic behaviour of probe functionalised magnetic beads after binding to a biomolecular target complementary to the probe. READ MORE

22. Capturing Air Pollutants : Photochemical Adsorption and Degradation of SO2, NO2 and CO2 on Titanium Dioxide
Abstract : Titanium dioxide (TiO2) is a material with many useful properties. It is used most widely as a pigment in white paint, although in technological research it is better known for its ability to catalyze chemical reactions during light absorption. READ MORE

23. Complex correlations between microstructure and magnetic behavior in hard nanomagnets : A study of the structural and magnetic properties of SrFe12O19 nanocrystallites
Abstract : Magnetic materials at the nanoscale are of huge scientific and technological interest, as theirmagnetic properties display remarkably different behavior compared to bulk-size. Among na-nostructured materials, M-type hexaferrite SrFe12O19 (SFO) nanoparticles (NPs) has becomeextremely appealing as promising candidate material for the renewal of permanent magnets ap-plications.

24. Nanoscale spin dynamics in ferromagnetic/normal-metal heterostructures for spin-logic application : Engineering of spin-torque efficiency in Co2FeAl/β-Ta and Ru/FeCo/Ru multi-layers
Abstract : In the present information age, people across the globe generate an enormous digital footprint. Therefore, it is necessary to store and process the information in an elegant way. Spin-logic circuits are being considered potential candidates beyond CMOS integrated computing due to high clock speed, non-volatility, and higher logical efficiency. READ MORE

25. Broadband and HF Radiation from Cloud Flashes and Narrow Bipolar Pulses
Abstract : Remote measurement of electric field generated by lightning has played a major role in understanding the lightning phenomenon. Even though other measurements such as photographic and channel base current have contributed to this research field, due to practical reasons remote measurements of electric field is considered as the most useful tool in lightning research.
