DESIGN OF A SCREENING PROCESS FOR THE DEVELOPMENT

Jackson, Marcus J. January 2011 (has links)
We have initiated the development of a screening platform to design a library of small molecules on the same solid support surface. This solid support surface, and the chemistry involved, can be utilized as a means of developing lead target molecules, namely ligands and catalysts. Evidence shows the successful assembly of both simple amino acids, as well as successful employment of our synthetic compounds. We support our efforts by showing compatibility for binding studies with larger macromolecules. Thus, intrigue remains by the prospects of this project. Challenges within our efforts are highlighted and emphasis is placed on presenting solutions to current issues, in order to attain further development. Notwithstanding difficulty, the desire to establish efficient processes for the discovery of lead target molecules and to ascertain the utility of our synthesized compounds, can be captured within this body of work. Lastly, the framework for continued efforts has been set to enable future progression. / Chemistry

Improved dielectric performance of polypropylene/multiwalled carbon nanotube nanocomposites by solid-phase orientation

Lin, X., Tian, J.-W., Hu, P.-H., Ambardekar, Rohan, Thompson, Glen P., Dang, Z.-M., Coates, Philip D. 26 September 2015 (has links)
Yes / By means of die drawing technique at rubber-state, effect of the orientation of microstructure on dielectric properties of polypropylene/multi-walled carbon nanotubes nanocomposites (PP/MWCNTs) was emphasized in this work. Viscoelasticity behavior of PP/MWCNTs with MWCNTs weight loadings from 0.25 to 5 wt% and dielectric performance of the stretched PP/MWCNTs under different drawing speeds and drawing ratios were studied for seeking an insight of the influences of dispersion and orientation state of MWCNTs and matrix molecular chains. A viscosity decrease (ca. 30%) of the PP/MWCNTs-0.25wt% melt was obviously observed owing to the free volume effect. Differential scanning calorimetry (DSC) and wide angle X-ray diffraction (WAXD) were adopted to detect the orientation structure and the variation of crystal morphology of PP/MWCNTs. Melting plateau regions, which indicated the mixed crystallization morphology for the stretched samples, were found in the DSC patterns instead of a single-peak for the unstretched samples. It was found that the uniaxial stretching process broke the conductive MWCNTs networks and consequently increased the orientation of MWCNTs as well as molecular chains along the tensile force direction, leading to an improvement of the dielectric performance.
