    • Pulsed Laser Ablation Deposition of Intermetallic Thin Films: A Study of Evolution of Metastable Phases and Ultra-fine Microstructures 

      Bysakh, Sandip (Indian Institute of Science, 2005-07-27)
      This thesis is devoted to the deposition of intermetallic thin films by laser ablation deposition (LAD) and their characterization. Pulsed laser ablation and subsequent deposition of the ablated vapours produces films under ...

    • Studies On The Application Of Liquid Membranes For The Removal Of Dissolved Metals From Effluents 

      Kumar, Vijaya S (Indian Institute of Science, 2005-07-21)
      Separation of dissolved metals from aqueous solutions using liquid membrane technology is highly advantageous owing to the degree of separation achieved, efficiency and application potential. In the present investigation ...

    • Structural Characteristics Of Randomly Packed Beds Of Spheres 

      Rao, Ammavajjala V S (Indian Institute of Science, 2005-07-20)
      Packed beds find extensive application in a wide variety of industries to cany out a large number of diverse processes. The main objective of the present work is to develop models to predict the arrangement of particles ...

    • Prediction Of Separation Factor In Foam Separation Of Proteins 

      Bhattacharjee, Samita (Indian Institute of Science, 2005-07-20)
      Polyhedral foams offer large gas-liquid interfacial area associated with a small amount of liquid. Therefore, if a solute adsorbs preferentially at the interface, the concentration of the solute in the foam will be greater ...

    • A Model For Heat Transfer In A Honey Bee Swarm 

      Bask, Tanmay (Indian Institute of Science, 2005-07-20)
      During spring, it has been observed that several thousand bees leave their hive, and settle on some object such as a tree branch. Some of the scout bees search for a suitable place where a new hive can be set up, while the ...
