Taking Nanolithography Beyond Semiconductors
A new technique of chemical patterning developed at Penn State combines conventional lithography with molecular self-assembly for the creation of multifunctional surfaces.
New Technique Studies How Plastic Solar Cells Turn Sunlight into Electricity
A plot of the wavelength of emitted infrared light vs. the time delay of the light emission provides information about the path of an electron within a plastic solar cell. This information about how the cell makes an electric current from light will lead to improvements in the efficiency and usable lifetime of solar cells.
Research Yields New Insights into the Cause of Diabetes
The insulin-secreting beta cells (green) normally exhibit a perinuclear cap of proinsulin (orange in top panel) whereas proinsulin is spread throughout the cytoplasm (orange in bottom panel) in many beta-cells of PERK-deficient mice, which are diabetic because of insufficient secretion of insulin.

Dragonfly's Metabolic Disease Provides Clues about Human Obesity
Penn State researchers studied the dragonfly, Libellula pulchella, and discovered that a supposedly harmless parasite triggers metabolic disorders similar to those found in humans afflicted with insulin resistance, type 2 diabetes, and obesity. Credit: Ruud Schilder

Ultraviolet Light Reveals Secrets of Nanoscale Electronic Materials
In this diagonally striped picture, the distance between each line is about 0.4 nanometers and each of the bands is several nanometers.
