Lonic liquid assisted exfoliation of layered magnesium diboride

Ratnam, Devina (Indian Institute of Technology Gandhinagar, 2016)

Two dimensional (2D) nanomaterials came into limelight with the discovery of graphene[1] in 2004. Graphene is a single atom thick layer of carbon having a hexagonal honeycomb lattice structure. It’s exceptional optoelectronic ...
Liquid antisolvent precipitation of curcumin: polymorphism, particle formation pathways and long term stability

Thorat, Alpana Ankush (Indian Institute of Technology, Gandhinagar, 2016)

The main objective of this work was to understand particle formation pathways and polymorphism of curcumin. Curcumin is a poorly water soluble ingredient found in turmeric (Curcumin longa). In this ork, curcumin was ...
Influence of phosphorylation on the foamability and stabilityof bovine serum albumin and citrus peel pectin (CPP) mixed foams

Modak, Shrikant Ramaro (Indian Institute of Technology Gandhinagar, 2016)

Bubbles are the vital component of many aerated food products which improves the properties like texture, flavour, appearance, shelf life etc. The foam stability of the food product is controlled by the protein polysaccharide ...
Influence of cooling rate on the self-assembly and rheology of hematite and silica nano-particles in hexagonal liquid crystal

Ankita, Verma (Indian Institute of Technology Gandhinagar, 2016)

Liquid crystals (LCs) are a fascinating state of matter due to their ability to demonstrate both solid as well as liquid properties. Non- ionic surfactant nonaethylene glycol dodecyl ether (C12 added to water organizes ...
Humidity induced agglomeration and caking behavior of ammonium perchlorate

Sharma, Ekta (Indian Institute of Technology Gandhinagar, 2016)

Ammonium perchlorate (AP) is an oxidizer used in explosives, fireworks and rocket motors. Due to its hygroscopic nature, it forms agglomerate and solid cake under humid conditions. This creates considerable problem during ...
Flow improvement of fine propellant powder using nano-additives

Dixit, Kirtika (Indian Institute of Technology Gandhinagar, 2016)

Ammonium Perchlorate (AP) is an oxidizer and major component for any solid omposite propellant fuel. The handling and processing of AP powder plays an important role in the performance of rocket fuel. AP being hygroscopic ...
An experimental strategy to mesure control room operator performance and analyze human failure probability

Iqbal, Mohd Umair (Indian Institute of Technology Gandhinagar, 2016)

Chemical process industries involve a lot of hazards like flammable hydrocarbons, toxic chemicals, etc. These hazards have a tendency to get transformed into accidents that often have catastrophic onsequences e.g. Bhopal ...
Exfoliation of layered MgB2 by integrating solid state and solvent based strategies

Swasti, Medha (Indian Institute of Technology Gandhinagar, 2016)
