Trap-Jaw Ants Spreading in Southeastern United States

Trap-jaw ant species are active hunters with venomous stings and jaws powerful enough to fling themselves through the air. According to new research, they are also spreading into new territory in the southeastern United States. The research was done by scientists at North Carolina State University, the Mississippi Entomological Museum, the University of California, Davis…

Organic Solar Cells More Efficient With Molecules Face-to-Face

New research from North Carolina State University and UNC-Chapel Hill reveals that energy is transferred more efficiently inside of complex, three-dimensional organic solar cells when the donor molecules align face-on, rather than edge-on, relative to the acceptor. This finding may aid in the design and manufacture of more efficient and economically viable organic solar cell…

Finding the Mix: Solar Cell Efficiency a Delicate Balance

Research from North Carolina State University reveals that solar cell efficiency is based upon a delicate balance between the size and purity of the interior layers, or domains. These findings may lead to better designs and improved performance in organic solar cells. Polymer-based solar cells are intended to have two domains, consisting of an electron…
