By placing nanometer sized quantum dots of gold across on the tops of the boron nitride nanotubes, researchers at Michigan Tech created a quantum-tunneling device that acts like a transistor at room temperature without using semiconducting materials.
For decades, electronic devices have been getting smaller, and smaller, and smaller. It’s now possible—even routine—to place millions of transistors on a single silicon chip.

We live in a world where digital information is exploding. Some 90% of the world’s data was generated in the past two years. The obvious question is: how can we store it all? In Nature Communications today, we, along with Richard Evans from CSIRO, show how we developed a new technique to enable the data capacity of a single DVD to increase from 4.7 gigabytes up to one petabyte (1,000 terabytes). Continue reading “Here’s how to fit 1,000 terabytes on a DVD” »
Docent Mindaugas Viliūnas works at the department of Solid State Electronics of Vilnius University. He has graduated from the faculty of Physics of this University in 1992, and seven years later, he has defended doctoral dissertation in physical science. His main area of research is charge carrier transport studies in materials with chaotic structure. In Vilnius University, he has been giving various special courses attended not only by future physics but also by chemists and mathematicians. In the first place, it is a course of Microprocessor technologies that is optional for all the students in the university.

End, begining No.9
Maybe our scientists lack healthy entrepreneurship, and businessmen – scientific approach? Therefore, sometimes it is hard to find a common language for them.
E. Leichteris. Let me say what I think about this. In my opinion, we need to strengthen Lithuanian science, and not necessarily in this entrepreneurial sense. When science becomes stronger, it would be beneficial to turn financial taps off for the science to learn some entrepreneurship. While there are funding schemes operating and scientists are allowed to do only what they are willing to do on state funds, scientists are not motivated to switch to some applied area.

New fiber optic technology from researchers at Boston University and the University of Southern California could ease Internet congestion and boost Internet bandwidth. Continue reading “New Fiber Optic Technology Could Boost Internet Bandwidth” »
3-D Self-Assembling Polymer Materials Could Lead to New Microchips.
As computer chips continue to shrink, developers are reaching the limits on how small they can make patterns for wires. A team of researchers at MIT believe they have a solution to this problem. By using self-assembling polymer materials that form tiny wires and junctions, they found a new way of making complex three-dimensional structures.
