Rowland junior Fellows

The Rowland Junior Fellows are selected to perform independent experimental research for five years, with full institutional support and access to the Institute's outstanding technical and scientific resources. The number of Rowland Junior Fellows will equal about ten over five years, with the first nine already appointed. Candidates in all the natural sciences (physics, chemistry, biology,...) as well as in engineering will be considered, with special attention given to interdisciplinary work and to the development of new experimental methods.
SEMINAR
Dr. Viktor Chikan, whose interests are the physical chemistry of nanostructures - optical, electrical properties and thermodynamics of doped quantum confined semiconductor systems, magnetic hyperthermia, from Kansas State University, Manhattan, KS, will speak at an 11AM seminar on July 17 2009.

Ozgur Sahin's Nanomechanical Sensing lab shows the flexibility of biomolecules at the microsecond timescale, monitored under physiologically relevant conditions, with high spatial resolution using a technique based on atomic force microscopy. See Latest Highlights, in Nature Nanotechnology.
Howard Berg reviews Escherichia coli's chemotaxis gain paradox in Progress in Biophysics and Molecular Biology.
Frans Spaepen named interim director of Center for Nanoscale Systems. For more detail, see article in The Crimson .
Shriram Ramanathan's group examine the microstructural effects on electrical conductivity relaxation in nanoscale ceria thin films, in The Journal of Chemical Physics.

Collaborative efforts at Harvard, Wesley Wong's Rowland group and Timothy A Springer's Medical School group , elucidate a feedback mechanism that the body uses to regulate the clotting of blood. Single-molecule manipulation techniques show that the von Willebrand factor A2 domain is key to this largely mechanical molecular feedback loop, as reported in Science.

BBC News reports that findings from Wong's and Springer's labs will aid in creation of more effective medicines for clotting disorders. Science Daily,in a more dramatic style, claims that these "Researchers Solve 'Bloodcurdling' Mystery: Molecular Basis For Regulation Of Blood Clotting."

Shriram Ramanathan's group shows that Ba0.60Sr0.40TiO3 (BST) thin films with non-conventional annealing by UV-photon irradiation possessed improved structural properties and dielectric response in their recent article in Journal of Materials Science. In an earlier article, they report "On the triggering mechanism for the metal-insulator transition in thin film VO2 devices: electric field versus thermal effects."
