Studies On Biodegradation Of Organic Flotation Collectors Using Bacillus polymyxa
(Indian Institute of Science, 2005-12-22)
Numerous organic reagents of diverse structural composition are employed in the froth flotation process for the beneficiation of non-metallic and sulphide ores. Alkyl xanthates are used as collectors for sulphide ores while ...
Development Of Cast Magnesium Alloys With Improved Strength
(2014-05-15)
Aim of the present work was to explore the possibility of improving strength of cast Mg by alloying additions, viz., Si and Zn+Al. All the alloys were produced by squeeze casting technique using squeeze pressure of 12MPa ...
A Study Of Crystallographic Texture, Residual Stresses And Mechanical Property Anisotropy In Aluminium Alloys For Space Applications
(2013-05-21)
Aluminium alloys, which are the most widely used materials in the aircraft and aerospace industries, find their applications due to high strength–to-density ratio, resistance to catastrophic fracture, high degree of ...
Pulsed Laser Ablation Deposition of Intermetallic Thin Films: A Study of Evolution of Metastable Phases and Ultra-fine Microstructures
(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 ...
Bubble Solid Interaction
(Indian Institute of Science, 2005-03-09)
The interaction of a bubble with solid surfaces, hydrophobic and hydrophilic, was investigated. When a bubble approaches towards a solid surface, a thin liquid film forms between them. The liquid in the film drains until ...
Microstructural Stability of Fully Lamellar and Duplex y-TiAl Alloys During Creep
(2018-03-06)
γ-TiAl based alloys have attracted considerable research interest in the past few decades and have gained niche high temperature applications in aero-engines and automobiles. As high temperature structural materials, these ...
Role Of Interfacial Phenomena In Bioprocessing Of Minerals Using Bacillus Polymyxa
(Indian Institute of Science, 2006-12-11)
In recent years there has been growing interest in bio-mineral processing due to its low operating costs and its application in processing lean-grade ores. Bioprocessing is a good alternative to conventional hydrometallurgy ...
Modeling Constitutive Behavior And Hot Rolling Of Steels
(Indian Institute of Science, 2006-03-17)
Constitutive behavior models for steels are typically semi-empirical, however recently neural network is also being used. Existing neural network models are highly complex with a large network structure i.e. the number ...
Kinetics Of Pressureless Infiltration Of Al-Mg Alloys Into Al2O3 Preforms : A Non-Uniform Capillary Model
(2009-03-06)
Al-Mg alloys spontaneously infiltrate into porous ceramic preform in a nitrogenous
atmosphere above 750 °C with Mg either pre-alloyed or introduced at the interface to
initiate the process. The governing process variables ...
