==============================

SPS students Tan Zher Yin, Garrick Lim, Ann Wee and Eileen Koh were amongst the winners at the inaugural NUS-ACS (American Chemical Society) Undergraduate Symposium 2017!

Tan's winning entry was based on his final year project "Divergent Synthesis of Spiro-Heterocycles via Lewis Acid Assisted Palladium Catalysis ". His project developed novel Lewis acid-assisted palladium-catalyzed divergent syntheses of spiro-heterocyclic compounds with high yields and selectivities.

The team of Lim, Wee and Koh presented their SPS project on "Application of Cholesteric Liquid Crystals as Temperature History Recorders ". Their research fabricated Cholesteric Liquid Crystal cells that served as durable and reusable indicators for monitoring the transport of temperature-sensitive materials.

The NUS-ACS Undergraduate Symposium was organized with the purpose of giving Chemistry majors a chance to experience presenting their research project to NUS staff and students. The symposium hoped to promote good scientific communication skills as well as inspire other undergraduates to take up research during their years in NUS. Hopefully, SPS will be well-represented at next year's event as well!
