A new organic 'ferroelectric,' economical and with low environmental impact, has been created The electronics industry has a remarkable impact on the environment, yet research is devising new solutions to reduce it. Among these, a new compound with an unutterable name, the diisopropylammonium bromide (DIPAB), a new ferroelectric material created by an international team of researchers that include Massimo Capone and Gianluca Giovannetti of Istituto Officina dei Materiali at CNR and of the...

At the heart of computing are tiny crystals that transmit and store digital information´s ones and zeroes. Today these are hard and brittle materials. But cheap, flexible, nontoxic organic molecules may play a role in the future of hardware. A team led by the University of Washington in Seattle and the Southeast University in China discovered a molecule that shows promise as an organic alternative to today´s silicon-based semiconductors. The findings, published this week in the...

NORUSCA II Camera Examines Auroras
2012-11-29 19:36:55

Lee Rannals for redOrbit.com — Your Universe Online Space-weather researchers joined forces to design and build NORUSCA II in order to help expand the understanding of auroras and other atmospheric events. NORUSCA II is a new camera with the capabilities of simultaneously imaging multiple spectral bands. The camera was tested at the Kjell Henriksen Observatory (KHO) in Svalbard, Norway. The camera produced the first-ever hyper spectral images of auroras and may have already...

Scientist Claims To Have Theory On Mysterious Balls Of Lightning
2012-10-19 19:35:24

Lee Rannals for redOrbit.com — Your Universe Online CSIRO scientist John Lowke thinks he has the mysterious balls of lightning thing figured out, despite himself never witnessing one. Lowke has written a new scientific paper, and has also given the first mathematical solution explaining the birth of ball lightning and how it is capable of passing through glass. Documented sightings of ball lightning have been made across the world for centuries, but no explanation of how it...

Spotting Sprites

[ Watch the Video: Sprites on Film ] April Flowers for redOrbit.com - Your Universe Online Fifty miles above the Earth, dancing high above the clouds during thunderstorms, a different kind of lightning flashes.  Bursts of red and blue light, known as sprites, flash for one thousandth of a second. Unless you happen to be looking directly at the flash, flying high over the clouds during a thunderstorm, you probably won't even see the sprite. One of the best places to get a good...

Tiny 'Firefly' Satellite Used To Flash Straight Into Lightning and Thunderstorms
2012-07-20 15:50:45

'CubeSat' will help solve mysteries of terrestrial gamma ray flashes, 1,000 times more powerful than 'northern lights' Imagine a fully-instrumented satellite the size of a half-gallon milk carton. Then imagine that milk carton whirling in space, catching never-before-seen glimpses of processes thought to be linked to lightning. The little satellite that could is a CubeSat called Firefly, and it's on a countdown to launch next year. CubeSats, named for the roughly four-inch-cubed...

By Harnessing Friction Between Surfaces, Triboelectric Generator Produces Electricity
2012-07-10 10:51:47

Polymer power Researchers have discovered yet another way to harvest small amounts of electricity from motion in the world around us — this time by capturing the electrical charge produced when two different kinds of plastic materials rub against one another. Based on flexible polymer materials, this "triboelectric" generator could provide alternating current (AC) from activities such as walking. The triboelectric generator could supplement power produced by nanogenerators that...

When we think of thunderstorms we have to remember the deadliest part of those storms and that is the lightning that occurs with them. Lightning is found in many forms. The first type of lightning is known as cloud to cloud meaning that the electric charge travels from one cloud to the other. The second type of lightning is the Cloud to Air meaning the lighting moves from the cloud and enters the clear air of the sky. A third type of lightning is the cloud to ground. This is the most...

A Radio Atmospheric signal (sometimes referred to as Sferic or Spheric), is a broadband electromagnetic impulse that occurs during atmospheric lightning discharges. Sferics spread out from the lightning source and can be received thousands of miles away. A sferic, depending on atmospheric conditions, may extend anywhere from a few kHz to several tens of kHz. Sferics from far reaching storms, over 1500 miles away, are generally offset in frequency range and may be picked up as tweeks. A...

Heat Lightning is actually faint flashes of lightning reflecting outward from distant thunderstorms. These flashes usually do not produce thunder as the storm is sometimes too far away to be heard. The term heat lightning got its name because it often occurs on hot summer nights and does not produce audible thunder. One reason heat lightning can be seen so far away is due to the reflection of the light bouncing off water particles in moist, humid air and as light is scattered throughout the...

Aurora -- The Polar Aurora are natural displays of light in the sky that can be seen with the unaided eye only at night. An auroral display in the Northern Hemisphere is called the aurora borealis, or the northern lights; in the Southern Hemisphere it is called the aurora australis. Auroras are the most visible effect of the sun's activity on the earth's atmosphere. The beautiful and often eerie curtains of light in the night time sky have been observed by people for millennia. An aurora...

call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
