Sustainable Two-Step Minlp Heat Exchanger Network Synthesis With Practical Detailed Design, Thanawat Boonvaerojkul Jan 2021

Sustainable Two-Step Minlp Heat Exchanger Network Synthesis With Practical Detailed Design, Thanawat Boonvaerojkul

Chulalongkorn University Theses and Dissertations (Chula ETD)

Due to sustainable development that focuses on energy conservation, decreasing emissions and environmental effect, the research of heat exchanger network synthesis (HENS) is still necessary and challenging. Most academic studies in the subject of HENS aim on reducing total annual cost (TAC) through optimal topology design without the detailed design costs of each heat exchanger in the network, resulting in conceptual HEN designs. Hence, the detailed design of shell and tube heat exchangers is recalculated for TAC and corrected area costs, including the pumping costs from overall pressure drop of heat exchangers. For a shell and tube heat exchanger, its …

Production And Characterization Of Escherichia Coli Outer Membrane Vesicles Displaying Anti-Muc1 Single-Chain Variable Fragment Via Spytag/Spycatcher System, Sedthawut Laotee

Chulalongkorn University Theses and Dissertations (Chula ETD)

Outer membrane vesicles (OMVs) secreted from Gram-negative bacteria have been discovered for a decade. Special features like high stability, ease of production, and intrinsic adjuvanticity highlight the use of OMVs in diverse applications such as vaccination, bioimaging, and multifunctional delivery systems. Synthetic biological approaches can functionalize OMVs to present heterologous proteins by expressing genetic fusion of target protein to outer membrane proteins. However, complex proteins cannot be incorporated into the OMVs due to lack of some post-translational modifications in bacteria. Herein, we demonstrated a convenient method for presentation of versatile proteins in OMVs with the implementation of the bio-ligation system …
