Monolayer-thick sheets of hexagonal boron nitride, or "white graphene," share many of the properties of graphene, including exceptional mechanical strength and thermal conductivity. But one important point of difference is its electrical conductivity, with graphene being a conductor, while white graphene is an insulator. Now researchers have developed a process to create a virtually perfect monolayer of white graphene, making a dream team pairing of graphene and white graphene substrate for use in next generation electronic devices a possibility.
Researchers at The University of Texas at Austin may have found a solution to one of the key problems holding back flexible, bendable electronics and soft robotics from mass production. Electronic circuits tend to crack and break when repeatedly subjected to bending or flexing, but a new self-healing gel may automatically repair these flaws as they develop.
Since first being synthesized by Andre Geim and Kostya Novoselov at the University of Manchester in 2004, there has been an extensive effort to exploit the extraordinary properties of graphene. However the cost of graphene in comparison to more traditional electronic materials has meant that its uptake in electronic manufacturing has been slow. Now researchers at the University of Glasgow have discovered a way to create large sheets of graphene at a fraction of the cost of current methods.
A time capsule that's not to be opened until the year 2957 has been recovered on the MIT campus. Discovered by workers building the new MIT.nano building, it contains a letter to the people of the next millennium and historical artifacts, including an experimental electronic component that once gave the transistor a run for its money.
non-volatile optical memory has been created by researchers working at the Karlsruhe
Institute of Technology (KIT) and the universities of Münster, Oxford, and
Exeter. Utilizing innovative phase-change materials to store information, the
new device promises to significantly improve processing speeds by effectively
eliminating the existing bottleneck of having to convert optical signals into electrical
signals for storage and then back again for transmission.
In today's world, vacuum tubes or radio valves seem as dead as high button shoes and buggy whips, but DARPA sees them as very much the technology of the future. As part of a new program, the agency is looking to develop new tube designs and manufacturing techniques for use in tomorrow's high-powered communications and radar systems.
Researchers from Germany, Japan and the United States have managed to create a tiny, reliable transistor assembled from a single molecule and a dozen additional atoms. The transistor reportedly operates so precisely that it can control the flow of single electrons, paving the way for the next generation of nanomaterials and miniaturized electronics.
A discovery at the Max Planck Institute for Chemical Physics of
Solids could pave the way for further leaps forward in the speed of
electronic systems. The finding that a material called niobium phosphide dramatically
increases its resistance in a magnetic field could lead to faster, higher-capacity hard drives and other electronic
If you’re into electronics as
a hobbyist, technician, or professional engineer, you know that you can spend
many hours designing circuits, sourcing components, and breadboarding or
soldering a project all together before you find out if your creation actually works. Wouldn’t
it make life simpler if you could just start with a basic, multi-function
controller and a few plug and play peripherals to get something – anything – up
and running straight away and then which you could tweak and add to as you go?
The makers of a new electronic design tool thought that this would be a good
idea too and have created Cubit, a make anything platform that allows drag and
drop software control over snap together hardware. Join Gizmag as we try a few builds to test out it out.
