Pics Of The Week

It's been a while since we highlighted some of the gorgeous pics from our photo contest. So this Thanksgiving week, we're offering up our honorable mentions for a visual feast.

In the Natural Polymers & Photonics Laboratory at Drexel University, researchers convert polysaccharides into nanofibers and thin films for use water purification and other applications. In Marjorie S. Austero's experiment, adding excess cross-linker to chitosan yielded the fine-fibered material seen in the colored SEM image.

Keith J. Fahnestock's chitosan-electrospinning run didn't go as planned. Rather than generating nanoscale fibers, the experiment produced micrometer-sized blobs. "In science, never cry over spilt milk. Take a picture of it instead," suggests Fahnestock, who is also part of the Drexel photography powerhouse.

Looking at inorganic compounds doesn't usually put chemists in a musical kind of mood. But there can be exceptions. "Solid vanadyl sulfate is one of the bluest compounds I know," wails Philip J. Squattrito, a chemistry professor at Central Michigan University.

Thomas Lazzara, a Ph.D. student at Georg August University's Goettingen Institute for Organic & Biomolecular Chemistry in Germany, captured this image of vesicles fluorescently labeled with Texas Red and filled with sucrose as they sank to the bottom of a petri dish filled with a low-density buffer.

Putting a literal twist on a comic strip illustrator's device, University of Rochester grad student Karen Chiang focused her thoughts on "Nontraditional Careers for Chemists" by Lisa M. Balbes by photographing the book cover through a bubble-filled glass of water.
