Chemistry of Synthesizing High-Quality Nanocrystals in Reaction Flask
High-temperature solution phase synthesis of different nanomaterials through bottom up approach would be presented. Synthesis of well studied quantum dots and doped nanocrystals in different solvent medium would be focused as model system. Our recent works on oriented attachment and formation of different complex nanostructures through ligand manipulation would be discussed.

Multi-GeV neutrinos due to neutron, anti-neutron oscillation in Gamma-ray Burst Fireballs
The long and short gamma-ray bursts are believed to be produced due tocollapse of massive stars and merger of compact binaries respectively.All these objects are rich in neutron and the jet outflow from these objectsmust have a neutron component in it. By postulating the neutron, anti-neutron oscillation in the gamma-ray burst fireball, we show that, 19-38 GeV neutrinos and anti-neutrinos can be produced due to annihilation of anti-neutrons withthe background neutrons. Observation of these neutrinoswill shed more light on the nature of the GRB progenitors and also be aunique signature of physics beyond the standard model. Apossible way of detecting these neutrinos in future is also discussed.
