Therapeutic Applications of Biodegradable Chitosan Based Polyelectrolyte Nanocapsules
(2018-01-18)
The past few years have witnessed significant work being directed towards drug delivery systems with layer-by layer (LbL) technique prominently featured as one of the most sought after approach. However, majority of the ...
Fracture and Deformation in Bulk Metallic Glasses and Composites
(2018-01-11)
Plastic flow in bulk metallic glasses (BMGs) localizes into narrow bands, which, in the absence of a microstructure that could obstruct them, propagate unhindered under tensile loading. In constrained deformation conditions ...
Synthesis and Characterization of Functionalized Electroactive Polymers for Metal Ion Sensing
(2018-02-06)
Metal ion contamination in surface and ground water is a major threat as it has a direct implication on the health of terrestrial and aquatic flora and fauna. Lead (Pb2+), mercury (Hg2+), cadmium (Cd2+), nickel (Ni2+), ...
Thiophene Derivative Photovoltaics : Device Fabrication, Optimization and Study of Charge Transport Characteristics
(2018-04-11)
In the recent years area organic photovoltaics is generating a lot of interests because whole process of synthesis and fabrication is less energy intensive process as well as it is cost effective compared to conventional ...
Densification Mechanisms for Spark Plasma Sintering in Alumina and Alumina Based Systems
(2018-03-19)
The densification mechanisms of polycrystalline α-alumina by spark plasma sintering are highly contradictory, with different research groups suggesting diffusion to dislocation controlled mechanisms to be rate controlling. ...
Micro-scale Fracture Testing of Graded (Pt,Ni)Al Bond Coats
(2018-04-16)
PtNiAl bond coats are diffusion aluminide coatings deposited on superalloy based turbine blades for oxidation resistance and improved adhesion between the substrate and the YSZ thermal barrier coating on top. They are ...
Ion-Nitriding Of Maraging Steel (MDN 250A Grade) For Light Combat Aircraft Applications
(2009-05-12)
Maraging steels have got high strength and good toughness. Maraging steel MDN 250A grade is used for slat tracks on the leading edge of the wing of Light Combat Aircraft (LCA). This application requires high strength and ...
First-Principles Studies of Point Defects and Phase Transformations in Materials
(2018-01-18)
The functional and mechanical properties of a material are often determined by the defects in them. A thorough understanding of the relationship between the defects and the properties allows for tailoring a material’s ...
Some Processing and Mechanical Behavior Related Issues in Ti-Ni Based Shape Memory Alloys
(2017-11-30)
Shape memory alloys (SMAs) exhibit unique combination of structural and functional properties and hence have a variety of current and potential applications. The mechanical behaviour of SMAs, in particular the influence ...
Effect of Li Addition on the Plasticity of AZ31 Mg-Alloy
(2017-11-14)
Mg-alloys, despite being the lightest structural metallic materials, find limited applications due to their poor workability, which is due to the hcp structure that does not provide sufficient number of independent slip ...
