Program Highlights for year 2014

Living Smectics are sensitive to boundary Elasticity

‘Living Smectics’ are being studied by a Physics PhD

Summer Enrichment Program for High School Students, PSSI

The LRSM has organized a free, four week summer program for local high school students interested in materials science and engineering since 1993. Typically 24-28 students, usually juniors but occasionally well qualified sophomores, are accepted. Students are drawn from schools in the Delaware Valley within easy commuting distance of the LRSM.

Panel Discussion on Entrepreneurship, CTT and LRSM

This year, we collaborated with Penn’s Center for Technology Transfer (CTT) on a discussion panel "How to Start a Materials-based Company." CTT is in charge of transferring inventions and innovative knowledge to outside organizations for the benefit of society. The panel, geared mainly towards graduate students, focused on starting a materials science based company.

In Situ Repair of Nanocrystal Devices

Semiconductor nanocrystals are sensitive to air and solvents, which hinders wet-chemical processing under ambient conditions.

This problem has limited the scaling of nanocrystal device dimensions and large-scale device integration achievable by  conventional processing.

Phonons & Soft Spots in Two-dimensional Glasses and Crystals

The mechanical failure of amorphous systems is not well understood, but recent work by Liu and co-workers suggests that low-frequency vibrational modes are concentrated in localized regions, or “soft spots,” that are prone to rearrange.


Dendrimers are highly branched molecules. Amphiphilic glycodendrimers have been synthesized for the first time. These macro-molecules have tunable carbohydrate head groups and hydrophobic tails. The precise architecture of the dendrimers facilitates assembly of precise structures, including vesicles (glycodendrimersomes).
