Research yields new way to create poly-silicon as competitor for fossil fuel energy

Harnessing more than 30 years of photovoltaic research experience, a University of Arkansas engineering professor has found a way to increase sunlight-to-electricity conversion efficiency and reduce the cost of expensive materials needed for solar-cell production. This technological breakthrough will decrease cost-per-watt production of solar electricity to a point at which it can compete with traditional, fossil-fuel-based methods.

Hydrogels used to make precise new sensor

Researchers are developing a new type of biological and chemical sensor that has few moving parts, is low-cost and yet highly sensitive, sturdy and long-lasting. The "diffraction-based" sensors are made of thin stripes of a gelatinous material called a hydrogel, which expands and contracts depending on the acidity of its environment.

Researchers predict future of electronic paper devices

In the first published critical review of technical developments related to electronic paper devices (i.e., e-readers like the Amazon Kindle), UC researcher Jason Heikenfeld and industry counterparts review the next generation of these devices.

Research of microscopic worms may be useful in study of self-assembly of small structures

Nematodes, microscopic worms, are making engineers look twice at their ability to exhibit the "Cheerios effect" when they move in a collective motion. These parasites will actually stick together like Cheerios swimming in milk in a cereal bowl after a chance encounter "due to capillary force." This observation has made Virginia Tech engineers speculate about the possible impacts on the study of biolocomotion.

First successful operation of carbon nanotube-based integrated circuits manufactured on plastic substrates

As part of NEDO's Industrial Technology Research Grant Japan-Finland collaborative project, Professors Yutaka Ohno from Nagoya University in Japan and Esko I. Kauppinen from Aalto University in Finland along with their colleagues have developed a simple and fast process to manufacture high quality carbon nanotube-based thin film transistors (TFT) on a plastic substrate. They used this technology to manufacture the world's first sequential logic circuits using carbon nanotubes.

First images of proteins and viruses caught with an X-ray laser

It has been a dream of researchers for over a decade: image biological materials at high resolution using incredibly intense X-ray laser pulses. A research team has proven this principle at the Linac Coherent Light Source by forming images of the Photosystem I protein complex and particles of the Mimivirus.
