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.

Scientists find neurons communicate at a distance with electric fields

Researchers believed neurons in the brain communicated through physical connections known as synapses. However, EU-funded neuroscientists have uncovered strong evidence that neurons also communicate with each other through weak electric fields, a finding that could help us understand how biophysics gives rise to cognition.

Taming carbon nanotubes

Carbon nanotubes have many attractive properties, and their structure and areas of application can be compared with those of graphene, the material for whose discovery the most recent Nobel Prize was awarded. In order to be able to exploit these properties, however, it is necessary to have full control of the manufacturing process. Scientists at the University of Gothenburg are closing in on the answer.
