Ageing wooden power poles increase risk of fires
Research at RMIT University has proven conclusively that wooden poles used for electricity distribution deteriorate with age and that their electrical performance worsens over time.
ORNL finding has materials scientists entering new territory
Solar cells, light emitting diodes, displays and other electronic devices could get a bump in performance because of a discovery at the Department of Energy's Oak Ridge National Laboratory that establishes new boundaries ...
Graphene's piezoelectric promise
Engineers predict that graphene can be coaxed into acting piezoelectric, merely by punching triangular holes into the material.
Plasmonic device converts light into electricity
Restraint improves dielectric performance, lifespan
Just as a corset improves the appearance of its wearer by keeping everything tightly together, rigidly constraining insulating materials in electrical components can increase their energy density and decrease their rates ...
Exotic quantum states: A new research approach

Creasing to cratering: Voltage breaks down plastic (w/ Video)
A Duke University team has seen for the first time how soft polymers, such as wire insulation, can break down under exposure to electrical current.
New ways to tune electrical conductivity revealed by electron interaction
Researchers in Japan have demonstrated why the material Sr2IrO4, -- a transition metal oxide -- that was expected to be an electrical conductor is actually an insulator. Harnessing this materials unusu ...
Tunable plastic thermometers
(PhysOrg.com) -- Researchers at the Universities of Queensland and New South Wales in Australia have discovered that the ability of a plastic to conduct electricity can be tuned by exposure to an ion beam. ...
High magnetic fields coax new discoveries from topological insulators
(PhysOrg.com) -- Using one of the most powerful magnets in the world, a small group of researchers has successfully isolated signs of electrical current flowing along the surface of a topological insulator, ...
Diamonds cutting environmental impact
Diamonds are known as a girl's best friend due to their splendid sparkle, but they are also held in very high regard by industrialists, who prize their unmatched density, excellent thermal conduction and other properties.
Silicon oxide circuits break barrier: Nanocrystal conductors could lead to massive, robust 3-D storage
Rice University scientists have created the first two-terminal memory chips that use only silicon, one of the most common substances on the planet, in a way that should be easily adaptable to nanoelectronic ...
Researchers print field-effect transistors with nano-infused ink
(PhysOrg.com) -- Rice University researchers have discovered thin films of nanotubes created with ink-jet printers offer a new way to make field-effect transistors (FET), the basic element in integrated circuits.
Scientists transform polyethylene into a heat-conducting material
Most polymers -- materials made of long, chain-like molecules -- are very good insulators for both heat and electricity. But an MIT team has found a way to transform the most widely used polymer, polyethylene, ...
