Microstructural Developments and Mechanical Properties of Electroless Ni-B Coating
(2018-04-24)
Phase transformation behavior, micro structural development, mechanical and tribological properties of electroless Ni-B coating was characterized using different characterization techniques. As deposited electroless Ni-B ...
Development of Hybrid Organic/Inorganic Composites as a Barrier Material for Organic Electronics
(2018-04-16)
The ultra high barrier films for packaging find applications in a wide variety of areas where moisture and oxygen barrier is required for improved shelf-life of food/beverage products and for microbial free pharmaceutical ...
Effect of Heat Treatment and Modification on Flow and Fracture Behaviour of a Newly Developed Al-Si Based Cast Alloy
(2018-04-17)
The compression behavior of a newly developed near eutectic Al-Si based cast alloy with three different microstructures has been investigated in the present work. Microstructures with modified and unmodified Si particles ...
Interdiffusion Study in Group IVB, VB and VIB Refractory Metal-Silicon Systems
(2018-04-13)
The knowledge of diffusion parameters provides important understanding of many physical and mechanical properties of materials. In most of the applications silicides are grown by a diffusion controlled process mainly in ...
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 ...
