Theses
Fischer-Tropsch (F-T) synthesis is the controlled catalyzed conversion of synthesized (syn) gas, a mixture of hydrogen and carbon monoxide, to fuel grade alkanes or hydrocarbons. One of the objectives of NSF-CREST Bioenergy Center is to develop stable catalysts for F-T synthesis with the goal of conversion of syngas enriched with CO2 in microchannel microreactors to liquid fuels. In our previous work, the effect of silica and titania sol-gel as support for F-T studies using syngas (CO:H2; 1:3 or 1:2) was investigated and significant differences in the activities of Co, Fe, and Ru catalysts were observed. In order to investigate synergistic …

Concrete is the most used material for construction, and it is the most produced man-made product in the world. Concrete makes the contemporary architecture of the world conceivable and brings significant development to communities. Nevertheless, there are many downsides to the use of concrete such as the large amount of energy and water used in its production, large carbon footprint, shrinkage and expansion that can cause cracking and other failure mechanisms, and the required use of large amounts of material to ensure stability of concrete structures. These drawbacks create the need for engineering and tailoring the properties of concrete. An …
