Photooxidation Of Organosulfur Compounds Catalyzed By Iodo-Bodipy Derivatives Under Visible Light Irradiation, Piyamaporn Tangkasemsamran Jan 2017

Photooxidation Of Organosulfur Compounds Catalyzed By Iodo-Bodipy Derivatives Under Visible Light Irradiation, Piyamaporn Tangkasemsamran

Chulalongkorn University Theses and Dissertations (Chula ETD)

In this work, iodo-BODIPY derivatives, I-GB, 3I-GB, I-RB, were synthesized and used as photocatalysts for oxidation of organosulfurs such as thiols and thioethers into the corresponding disulfides and sulfoxides, respectively, as well as compared with benchmark photocatalyst, rose bengal. All BODIPY derivatives were successfully synthesized in good yields (36-80%) via condensation reaction between 4-iodobenzaldehyde and corresponding pyrroles, followed by oxidation with DDQ and complexation with BF3.OEt2. Among all synthesized BODIPYs, 3I-GB and 3I-RB showed relatively low quantum yield (0.053-0.054) with high singlet oxygen generation efficiency under green LED suggesting that both of them could serve as good photocatalysts for sulfur …

Tribological Characterization Of Lapping Lubricant In Hard Disk Drive Fabrication, Sawanee Jitphayomkun Jan 2017

Tribological Characterization Of Lapping Lubricant In Hard Disk Drive Fabrication, Sawanee Jitphayomkun

Chulalongkorn University Theses and Dissertations (Chula ETD)

One of the most important processes in hard disk drive fabrication is the lapping process. As two bodies are in contact, the friction occurs, and the softer material can be worn out by the harder. By using lubricant in the lapping process, it does not only reduce the friction, but it also transfers heat and captures debris away from the surface contacts. This thesis work focused on the effects of tribological parameters toward the characteristics of lubricants, using ball-on-disk tribometer. The tribological behaviors between using different base lubricants were investigated. At the same condition as final lapping process, EG-based and …
