New Technique May Open Up an Era of Atomic-scale Semiconductor Devices

Researchers at North Carolina State University have developed a new technique for creating high-quality semiconductor thin films at the atomic scale – meaning the films are only one atom thick. The technique can be used to create these thin films on a large scale, sufficient to coat wafers that are two inches wide, or larger.

Moth-Inspired Nanostructures Take the Color Out of Thin Films

Inspired by the structure of moth eyes, researchers at North Carolina State University have developed nanostructures that limit reflection at the interfaces where two thin films meet, suppressing the “thin-film interference” phenomenon commonly observed in nature. This can potentially improve the efficiency of thin-film solar cells and other optoelectronic devices.

Iron Man, 3-D Printing and the Responsibility of Power

If you’ve seen Iron Man 3, you know that – SPOILER ALERT!!!! – billionaire inventor Tony Stark reveals dozens of specialized Iron Man power suits. As fantastic as the suits are, the technology Stark likely uses to make them is not far removed from reality – and neither are the big questions that such technology…

Injectable Nano-Network Controls Blood Sugar in Diabetics for Days at a Time

In a promising development for diabetes treatment, researchers have developed a network of nanoscale particles that can be injected into the body and release insulin when blood-sugar levels rise, maintaining normal blood sugar levels for more than a week in animal-based laboratory tests. The work was done by researchers at North Carolina State University, the…

Older Is Wiser: Study Shows Software Developers’ Skills Improve Over Time

There is a perception in some tech circles that older programmers aren’t able to keep pace with rapidly changing technology, and that they are discriminated against in the software field. But a new study from North Carolina State University indicates that the knowledge and skills of programmers actually improve over time – and that older…
