'Accelerator on a chip' demonstrated
In an advance that could dramatically shrink particle accelerators for science and medicine, researchers used a laser to accelerate electrons at a rate 10 times higher than conventional technology in a nanostructured ...
Tiny chip mimics brain, delivers supercomputer speed
Researchers Thursday unveiled a powerful new postage-stamp size chip delivering supercomputer performance using a process that mimics the human brain.
Breakthrough allows fast, reliable pathogen identification
Life-threatening bacterial infections cause tens of thousands of deaths every year in North America. Increasingly, many infections are resistant to first-line antibiotics. Unfortunately, current methods of culturing bacteria ...
Scientists use DNA to assemble a transistor from graphene
(Phys.org) —Graphene is a sheet of carbon atoms arrayed in a honeycomb pattern, just a single atom thick. It could be a better semiconductor than silicon – if we could fashion it into ribbons 20 to 50 ...
Future phones and laptops could have speakers made of carbon nanotubes
Teleportation with engineered quantum systems
A team of University of Queensland physicists has transmitted an atom from one location to another inside an electronic chip.
Researchers combine logic, memory to build a 'high-rise' chip
For decades, the mantra of electronics has been smaller, faster, cheaper. Today, Stanford engineers add a fourth word - taller.
Controlling magnetic clouds in graphene
(Phys.org) —Wonder material graphene can be made magnetic and its magnetism switched on and off at the press of a button, opening a new avenue towards electronics with very low energy consumption.
Quantum teleportation on a chip
The core circuits of quantum teleportation, which generate and detect quantum entanglement, have been successfully integrated into a photonic chip by an international team of scientists from the universities ...
Harnessing the potential of quantum tunneling: Transistors without semiconductors
(Phys.org) —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.
Silicon Valley marks 50 years of Moore's Law
Computers were the size of refrigerators when an engineer named Gordon Moore laid the foundations of Silicon Valley with a vision that became known as "Moore's Law."
An unlikely competitor for diamond as the best thermal conductor
An unlikely material, cubic boron arsenide, could deliver an extraordinarily high thermal conductivity – on par with the industry standard set by costly diamond – researchers report in the current issue of the journal ...
A bright future for LEDs
A single wafer-level LED chip that produces more than 150 Watts of light output has been made in work form China. This level of output from a single chip makes applications for LEDs in high power lighting ...
