| Researchers use oxides to flip graphene conductivity Posted: 26 Jan 2015 01:46 PM PST A team of researchers has demonstrated a new way to change the amount of electrons that reside in a given region within a piece of graphene, they have a proof-of-principle in making the fundamental building blocks of semiconductor devices using the 2-D material.  |
| Electronic circuits with reconfigurable pathways closer to reality Posted: 26 Jan 2015 09:49 AM PST Multitasking circuits capable of reconfiguring themselves in real time and switching functions as the need arises -- this is the promising application stemming from a new discovery. Other potential uses: miniaturizing our electronic devices and developing resilient circuits.  |
| Nanoshuttle wear and tear: It’s the mileage, not the age Posted: 26 Jan 2015 08:20 AM PST As nanomachine design advances, researchers are moving from wondering if the nanomachine works to how long it will work -- an important question as there are so many potential applications, e.g., for medical uses including drug delivery and early diagnosis. Scientists observed a molecular shuttle powered by kinesin motor proteins and found it to degrade when operating, marking the first time degradation has been studied in detail in an active, autonomous nanomachine.  |
| Researchers make magnetic graphene Posted: 26 Jan 2015 06:59 AM PST Graphene has many desirable properties. Magnetism alas is not one of them. Magnetism can be induced in graphene by doping it with magnetic impurities, but this tends to disrupt graphene's electronic properties. Now physicists have found a way to induce magnetism in graphene while also preserving graphene's electronic properties. They have accomplished this by bringing a graphene sheet very close to a magnetic insulator -- an electrical insulator with magnetic properties.  |
| Visualizing interacting electrons in a molecule Posted: 26 Jan 2015 06:59 AM PST Scientists have succeeded in directly imaging how electrons interact within a single molecule. Understanding this kind of electronic effects in organic molecules is crucial for their use in optoelectronic applications, for example in organic light-emitting diodes, organic field-effect transistors and solar cells.  |
| Entanglement on a chip: Breakthrough promises secure communications and faster computers Posted: 26 Jan 2015 06:57 AM PST A team of scientists has developed, for the first time, a microscopic component that is small enough to fit onto a standard silicon chip that can generate a continuous supply of entangled photons.  |
| Infrared imaging technique operates at high temperatures Posted: 23 Jan 2015 04:02 PM PST A research team took advantage of superlattice architecture and new materials to develop a detector that does not require low temperatures to operate.  |
