Synthesis Of Microgel Polymers As Catalysts, Hannah N. Miller
Synthesis Of Microgel Polymers As Catalysts, Hannah N. Miller
Chemistry & Biochemistry Undergraduate Honors Theses
New developments in organic synthesis show promise in achieving the best catalytic properties for the hydrolysis of glycosidic bonds through microgel polymers and transition metal complexes. A monomer mix of ethylene glycol dimethacrylate, butyl acrylate, and styrene form miniemulsion polymers after sonication and exposure to UV light. Gravimetrical analysis is used to determine the most suitable polymerization conditions by performing experiments at varying pH values, temperatures, monomer amounts, initiator amounts, and lamp heights. The final data show that the best polymerization conditions are a pH of 10.50 at 0°C with a high monomer ratio, 20% initiator amount, and a lamp …

Improving Photocatalytic Activity By Appending A Quinone To Ruthenium Polypyridyl Complex, Amy N. James
Chemistry & Biochemistry Undergraduate Honors Theses
By converting natural light energy into chemical energy, chemists are studying ways to take advantage of clean energy. The rising precedence of “green chemistry” has led to academic interest in the activity of photocatalysts and harnessing visible light in an efficient, accessible, and safe manner. Photochemistry is an upcoming and fascinating field of study that has made significant progress, but also has great potential for future work. By utilizing light as a natural energy source, many reaction processes in chemistry can be viewed with a new perspective. Ru(bpy)32+ is one of the most widely used photocatalysts. An efficient …
