Methods For Integrative Analysis Of Genomic Data, Paul Manser Jan 2014

Methods For Integrative Analysis Of Genomic Data, Paul Manser

Theses and Dissertations

In recent years, the development of new genomic technologies has allowed for the investigation of many regulatory epigenetic marks besides expression levels, on a genome-wide scale. As the price for these technologies continues to decrease, study sizes will not only increase, but several different assays are beginning to be used for the same samples. It is therefore desirable to develop statistical methods to integrate multiple data types that can handle the increased computational burden of incorporating large data sets. Furthermore, it is important to develop sound quality control and normalization methods as technical errors can compound when integrating multiple genomic …


Catalytic Activity Of Heteropoly Tungstophosphoric Acid Supported On Partially Reduced Graphene Oxide Prepared By Laser And Microwave Irradiation, Mark Paul Jimena Dailo Jan 2014

Catalytic Activity Of Heteropoly Tungstophosphoric Acid Supported On Partially Reduced Graphene Oxide Prepared By Laser And Microwave Irradiation, Mark Paul Jimena Dailo

Theses and Dissertations

The solid acid catalyst of the Keggin-type 12-tungstophosphoric acid (H3PW12O40, HPW) is supported on partially reduced graphene oxide (PRGO) nanosheets for acid-catalyzed reactions. HPW is a new class of catalyst with a good thermal stability and high Bronsted acidity in order to replace common mineral acids. However, it has low specific surface area (1-5 m2/g). Therefore, the possibility of PRGO as a catalytic support for HPW is investigated due to its high surface area (2630 m2/g) and good thermal stability. The synthesis of HPW-GO catalyst is prepared using microwave and …
