Breakthrough could launch organic electronics beyond cell phone screens Researchers used ultraviolet light to excite molecules in a semiconductor, triggering reactions that split up and activated a dopant Credit: Jing Wang and Xin Lin

A discovery by Princeton University, Georgia Institute of Technology and Humboldt University in Berlin points the way to more widespread use of an advanced technology known as organic electronics. The research focuses on organic semiconductors, a class of materials prized for their applications in emerging technologies such as flexible electronics, solar energy conversion, and high-quality color displays for smartphones and televisions...

Clinical Evidence Supports a Protective Role for CXCL5 in Coronary Artery Disease. The American Journal of Pathology, 2017; DOI: 10.1016/j.ajpath.2017.08.006

Research showed much lower levels of the protein CXCL5 in older people with clogged arteries. The buildup of plaque in the heart’s arteries is an unfortunate part of aging. But by studying the genetic makeup of people who maintain clear arteries into old age, researchers led by UNC’s Jonathan Schisler, PhD, have identified a possible genetic basis for coronary artery disease (CAD), as well as potential new opportunities to prevent it.

According to research published in the American Journal of Pathology, the protein CXCL5 is found in much higher levels in older adults with much clearer heart arteries...

3D Printers to turn century-old theory into complex Schwarzites. Rice University engineers are using 3D printers to turn structures that have until now existed primarily in theory into strong, light and durable materials with complex, repeating patterns. The porous structures called schwarzites are designed with computer algorithms, but Rice researchers found they could send data from the programs to printers and make macroscale, polymer models for testing...

Scientists have synthesized a compound with 3 ruthenium atoms connected by an organic molecule that absorbs near-infrared light to produce hydrogen from water. The absorbed light stimulates electrons to ‘jump’ into orbitals that do not exist in other, similar compounds. This is the first successful use of infrared light to reduce water into hydrogen, which can be used for energy conversion and storage, and other industrial purposes in a future sustainable energy society.

Solar cells must absorb light of particular wavelengths, depending on how much energy the cell needs to drive the reaction...
