| Microbot muscles: Chains of particles assemble and flex Posted: 10 Nov 2014 12:09 PM PST In a step toward robots smaller than a grain of sand, researchers have shown how chains of self-assembling particles could serve as electrically activated muscles in the tiny machines. |
| A billion holes can make a battery Posted: 10 Nov 2014 09:42 AM PST Researchers have invented a single tiny structure that includes all the components of a battery that they say could bring about the ultimate miniaturization of energy storage components. |
| Good Vibrations Give Electrons Excitations That Rock an Insulator to Go Metallic Posted: 10 Nov 2014 09:35 AM PST Scientists have made an important advancement in understanding a classic transition-metal oxide, vanadium dioxide, by quantifying the thermodynamic forces driving the transformation. |
| On-demand conductivity for graphene nanoribbons Posted: 10 Nov 2014 08:02 AM PST Physicists have devised a theoretical model to tune the conductivity of graphene zigzag nanoribbons using ultra-short pulses. Physicists have, for the first time, explored in detail the time evolution of the conductivity, as well as other quantum-level electron transport characteristics, of a graphene device subjected to periodic ultra-short pulses. To date, the majority of graphene studies have considered the dependency of transport properties on the characteristics of the external pulses, such as field strength, period or frequency. |
