GRAND PRIZE!

Congratulations to Kenneth Hanson, the Grand Prize Winner of the C&EN’s Chemistry in Pictures Photo Contest for 2014*. Hanson, who is a chemistry professor at Florida State University, will receive a brand new Canon Digital SLR camera, and his winning photo will be featured in an upcoming issue of Chemical & Engineering News. 

From the FSU website: “The Hanson research group focuses on the design, synthesis and characterization of light absorbing and emitting molecules for various applications. The design of the chromophores is guided by our electrochemical and photophysical characterization of the molecules/devices with an emphasis on understanding their structure-property relationships. This work will open the door to more efficient dye-sensitized solar cells (DSSCs), selective sensors/probes for biologically relevant metal ions, and a new approach to catalysis involving light-assisted reaction pathways.”

BRILLIANT BLUE

Polymer shavings from a scintillation sphere (half-sphere, shown at bottom right) emit blue light under an ultraviolet lamp. Kenneth Hanson of Florida State University and colleagues are modifying polymers such as polystyrene and polyvinyltoluene to increase the efficiency at which these materials convert gamma-rays to visible light. The ability to detect gamma rays has a number of applications, including the detection of nuclear weapons.
