Analyses Of Densely Crosslinked Phenolic Systems Using Low Field Nmr, Jigneshkumar Patel Jan 2017

Analyses Of Densely Crosslinked Phenolic Systems Using Low Field Nmr, Jigneshkumar Patel

Doctoral Dissertations

A uniform dispersion of reactants is necessary to achieve a complete reaction involving multi-components, especially for the crosslinking of rigid high-performance materials. In these reactions, miscibility is crucial for curing efficiency. This miscibility is typically enhanced by adding a third component, a plasticizer. For the reaction of the highly crystalline crosslinking agent hexamethylenetetramine (HMTA) with a strongly hydrogen-bonded phenol formaldehyde resin, furfural has been traditionally used as the plasticizer. However, the reason for its effectiveness is not clear. In this doctoral thesis work, miscibility and crosslinking efficiency of plasticizers in phenolic curing reactions are studied by thermal analysis and spectroscopic ...


The Impact Of Active Aerodynamics On Motorcycles Using Computational Fluid Dynamics Simulations, Aditya Sripathi Jan 2017

The Impact Of Active Aerodynamics On Motorcycles Using Computational Fluid Dynamics Simulations, Aditya Sripathi

All Theses, Dissertations, and Other Capstone Projects

Motorcycles are mostly utilized by commuters whose requirements are cheap and affordable transportation from point A to point B. Motorcycles also provide means to tour various places and have a leisure time for the majority of motorcyclists. Unfortunately, with pros also come cons such as accidents which are disabling or life-taking. According to motorcycle crash statistics produced every year, the majority of motorcycle crashes are caused due to facing unexpected obstacles in the path causing collisions due to insufficient braking time. Thus, this thesis serves as a mean to overcome this issue and provide a technological solution to the world ...
