‘Nanodaisies’ Deliver Drug Cocktail to Cancer Cells

Biomedical engineering researchers have developed daisy-shaped, nanoscale structures that are made predominantly of anti-cancer drugs and are capable of introducing a “cocktail” of multiple drugs into cancer cells. The researchers are all part the joint biomedical engineering program at North Carolina State University and the University of North Carolina at Chapel Hill.

Researchers Test Distributed Computing as Defense Against Cyberattacks on Power Grids

Imagine a cyberattack that does serious damage to the U.S. power grid. The results wouldn’t be pretty. The power grid is complicated, divided up into sections that cover everything from a single municipal area (like New York City) to large regions (like the entire state of California). But each of those sections is controlled by…

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…

Why a New Catalyst for Hydrogen Production May Be a Big Deal

A research team led by Linyou Cao at NC State has shown that a one-atom thick film of molybdenum sulfide (MoS2  ) may work as an effective catalyst for creating hydrogen. Hydrogen holds great promise as an energy source, but the production of hydrogen from water electrolysis – freeing hydrogen from water with electricity – currently…

Energy Use Drops Over Break

Students, faculty and staff helped NC State avoid more than a quarter-million dollars in utility costs over winter break. But a big reduction in the university's utility budget means we have to keep up the good work. Learn how to reduce your energy and water use on campus.

Study: Electric Drive Vehicles Have Little Impact on U.S. Pollutant Emissions

A new study from North Carolina State University indicates that even a sharp increase in the use of electric drive passenger vehicles (EDVs) by 2050 would not significantly reduce emissions of high-profile air pollutants carbon dioxide, sulfur dioxide or nitrogen oxides.

New, Simple Technique May Drive Down Biofuel Production Costs

Researchers at North Carolina State University have developed a simple, effective and relatively inexpensive technique for removing lignin from the plant material used to make biofuels, which may drive down the cost of biofuel production.

Researchers Find Ways for More Efficient Control of Wind Power

NOTE: This release has been revised since it was first posted Jan. 2. In the initial version, we stated that wind power’s potential to have a negative impact on the grid were primarily due to the variability of the wind. In fact, wind power’s potential to have a positive or negative impact on the grid…
