Aggregation and Fate of Fullerene Nanoparticles in Aquatic Environments

Chen K.L., Elimelech M., Yale University, US

Fullerene has unique chemical properties and physical structure, and is emerging in a wide range of electronics and biomedical applications. However, toxicity studies have raised concern that fullerene may have adverse human health effects. With [...]

New Guidelines for Selecting Best Extraction Methods of EPS Using Atomic Force Microscopy

Kang S., Ahn Y., Choi H., Elimelech M., Yale University, US

In this study, we applied AFM to develop the guideline during the selection of best extraction methods for exocellular polymeric substances (EPS). A single cell of S. cerevisiae was glued at the end of the [...]

The Dielectric Boundary Force in Ion Channels: The Case of Gramicidin

Nadler B., Hollerbach U., Eisenberg R.S., Yale University, US

In an electrostatic problem with different dielectric regions, a charge in one region induces surface charges at all dielectric boundaries, which, in turn, exert an often neglected force on the charge that induced them. This [...]

Ionic Diffusion Through Protein Channels: From molecular description to continuum equations

Nadler B., Schuss Z., Singer A., Eisenberg R.S., Yale University, US

Diffusion of particles through a microscopic region, as in ionic permeation through protein channels, is an important phenomenon in many diverse fields. Permeation through ion channels occurs on a microsecond time scale, far longer than [...]

Templated Growth of Single Walled Carbon Nanotubes by CO Disproportionation on Cobalt Incorporated MCM-41

Ciuparu D., Lim S., Chen Y., Dobek F., Harding D., Haller G., Pfefferle L., Yale University, US

Single-walled carbon naotubes of uniform size were produced inside the pore system of cobalt substituted MCM41 mesoporous molecular sieve. Proof of concept has been achieved and preliminary results are reported.
