LEWISBURG, Pa. — Bucknell University students participating in summer undergraduate research projects will present a poster session Wednesday, July 29, from 2 to 4 p.m. in the Terrace Room of the Elaine Langone Center at Bucknell.

The annual event highlights the summer research of students and their faculty advisers in astronomy, biology, chemistry, geology, mathematics and physics as well as engineering, and is sponsored by the Bucknell chapter of Sigma Xi, the scientific research society.

The 40 to 50 students conducted their research in a wide range of topics. Student researchers include:

·    Bucknell sophomore Cathy Meade and Penn State student Kasei Kochel worked with biology professor Matt McTammany on a Susquehanna River Assessment to determine the variability in water quality across space and time. Water quality was measured in the West Branch in Milton, the North Branch in Danville, and the main stem below the confluence in Hummels Wharf using probes with sensors.

·    First-year student Giorgina Alfonso, sophomore Nick Gonsalves and junior Daniel Wang worked with biology professors Duane Griffin and Mark Spiro on an inventory of the more than 1,700 trees on the campus to build a database for the Bucknell University Arboretum.

·    Sophomore Amy Goodfriend compared turtle shell constructions in two subspecies, and sophomore Christine Vega explored the functional implications of shell shape differences between males and females of two turtle species, both with biology professor Tristan Stayton.

Research topics include clonal patterns of coexisting palmetto species in Florida's xeric uplands; chemical models of iron(III) in natural waters; the FRAP method (ferric reducing antioxidant power) as an in-capillary electrophoresis assay; gene flow and host-race formation of the gall-boring beetle; vibrational energy transfer (vet) of  O3, N2O and CO2 with O(3P), and applications in atmospheric heating and cooling; synchronization and other behaviors of coupled oscillators; and surface modification of gold nanoparticles using oxygen plasma.

Other topics are developing an XML language for credible wireless network simulation; measuring lifetimes of positrons in porous materials; polarization splitter for photonic integrated circuit; direct synthesis of macrocyclic vinyl polymers using nitrones; and the effect of Lewis acids on the synthesis of poly(t-butyl vinyl ether) initiated by n-methyleneamines.
