Cryogenic Technique For Processing Steel Treatment, Ajit Behera
Ajit Behera
Cryogenics or deep freezing have been around for quite some time. There is documented research from as far back as the 1930’s where German companies used it on components of jumbo aircraft engines. Cryogenic processing had its US origins in the 1940s. Cold treatments or sub zero treatments are done to make sure there is no retained austenite during quenching. Cryogenics is a relatively new process and to eliminate retained austenite, the temperature has to be lowered, but one that using correct procedures can bring substantial economic benefits. In cryogenic treatment the material is to be deep freeze temperatures of …

In the present piece of research work focuses on grafting Acrylic acid with HPMC to obtain copolymers with improved properties, biodegradable and biocompatible that will be used as hydrogel or water absorbing polymers. To develop a prolong release activity drug delivery system for the medication purpose to enhance drug activity and reduce the frequency of dose via this hydrogel. A novel HPMC-g- acrylic acid hydrogel was prepared by in-situ emulsifier free emulsion polymerization using benzyl peroxide as an initiator through 1-stage grafting. Acrylic Acid could intercalate into layers of HPMC and form graft composites through in situ graftpolymerization with acrylic …

The conventional materials are nowadays not sufficient to cater to the variety of uses and exposure to various environments that may take place while they are put into use. Hence this leads to the development of composites, which nearly suffice the above two conditions. Composite material is a material composed of two or more distinct phases (matrix phase and reinforcing phase) and having bulk properties significantly different from those of any of the constituents. In this developing age for iron industry there is large demand for spherodial Graphite iron (S.G. Iron). S.G. Iron also known as a composite in which …

Nanoparticles are widely due as Sustained Release Drug Delivery System. Due to their smaller size of controlled drug release potential, targeting ability, enhancement of therapeutic efficacy and reduction of toxicity. Nifedipine one of the calcium channel blocker use for the management of hypertension. Spray drier technique develops Nifedipine loaded nanoparticle. Primary superimulsion phase contains Drug (Nifedipine), Polymer (Ethylcellulose) & suitable non-aqueous Solvent (Dichloromethane) which are sprayed over secondary phase containing aqueous solvent with dispersing polymers (PVA) are prepared by taking drug to polymer weight ratio of 20:90. Formation of films on the surface of secondary phase dried, sieved & forward …
