When amazing new computers and other electronic devices emerge, they will have been conceived and incubated in university laboratories like that of Dr. Chris Gorman, professor of chemistry at North Carolina State University. There, the scientist and his multidisciplinary team are working to build, molecule by molecule, a nanoscale transistor.
A patterned collection of molecules
created and visualized using scanning tunneling microscopy like that used to help create the nanoscale transistor.
Data collected by R. Fuierer
That’s an electronic switch so small it can only be seen with a high-tech device called a scanning tunneling microscope. And if you go to the library to find the “how-to” book, says Gorman, “most of the pages will be blank, because nobody yet knows how to do it.”
And that, for the chemists, engineers and students engaged in the project, is what makes their painstaking, pioneering research so satisfying. If they can design and construct a nanoscale transistor, Gorman, his colleagues and his students will have filled in many of the blank pages in the how-to book. The field is so new, the research avenues so unexplored, that each experiment, each variation, helps write that book.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
