[ Watch the Video: What Do LCD TVs And Candles Have In Common? ] Lee Rannals for redOrbit.com - Your Universe Online Paraffin wax and an LCD television have a lot more in common than you might think, according to a new study published in The Journal of Chemical Physics. Researchers at the Physics and Material Science Research Unit of the University of Luxembourg made the connection between paraffin wax and liquid crystal while studying the crystallization process of wax on a...

Researchers Grow Liquid Crystal 'Flowers' That Can Be Used As Lenses
2013-12-22 17:45:14

University of Pennsylvania A team of material scientists, chemical engineers and physicists from the University of Pennsylvania has made another advance in their effort to use liquid crystals as a medium for assembling structures. In their earlier studies, the team produced patterns of “defects,” useful disruptions in the repeating patterns found in liquid crystals, in nanoscale grids and rings. The new study adds a more complex pattern out of an even simpler template: a...

Scientist Creates Morphing Material That Has Huge Potential

[ Watch The Video: Morphing Material With Great Potential ] Rice University Heating a sheet of plastic may not bring it to life – but it sure looks like it does in new experiments at Rice University. The materials created by Rice polymer scientist Rafael Verduzco and his colleagues start as flat slabs, but they morph into shapes that can be controlled by patterns written into their layers. The research is the subject of a new paper in the Royal Society of Chemistry journal...

Developing Highly Rugged, Lightweight Liquid Crystal Displays
2013-09-04 09:18:22

AlphaGalileo Foundation Displays for smartphones or tablet-PCs should be highly ruggedized at little overall weight. For curved displays, that might play a role in advertising or the automotive sector, a certain flexibility of the display materials is mandatory. Together with national and international industry partners, scientists at the University of Stuttgart have started the development of very robust and extremely lightweight displays within the research project LiCRA. Instead of...

Nanomachines: Devices Of The Future
2013-08-28 09:42:10

Institute of Physical Chemistry of the Polish Academy of Sciences An innovative measurement method was used at the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw for estimating power generated by motors of single molecule in size, comprising a few dozens of atoms only. The findings of the study are of crucial importance for construction of future nanometer machines – and they do not instil optimism. Nanomachines are devices of the future. Composed of a...

Light Slowed Down To A Crawl In Liquid Crystal Matrix

The Optical Society New technique could find uses in highly sensitive interferometers and other measuring devices Light traveling in a vacuum is the Universe’s ultimate speed demon, racing along at approximately 300,000 kilometers per second. Now scientists have found an effective new way to put a speed bump in light’s path. Reported today in The Optical Society’s (OSA) open-access journal Optics Express, researchers from France and China embedded dye molecules in a liquid crystal...

New Ways To Study How Ordered Materials Arrange Themselves
2013-05-21 14:04:23

A fried breakfast food popular in Spain provided the inspiration for the development of doughnut-shaped droplets that may provide scientists with a new approach for studying fundamental issues in physics, mathematics and materials. The doughnut-shaped droplets, a shape known as toroidal, are formed from two dissimilar liquids using a simple rotating stage and an injection needle. About a millimeter in overall size, the droplets are produced individually, their shapes maintained by a...

Scientists have unearthed a new dynamic process induced by strong electric fields in thin liquid crystal cells Liquid crystal displays are ubiquitous. Now, Polish physicists have demonstrated that the application of a very strong alternating electric field to thin liquid crystal cells leads to a new distinct dynamic effect in the response of the cells. The theory of spatio-temporal chaos explains this effect. It was elucidated by Wojciech Jeżewski and colleagues from the...

By showing that tiny particles injected into a liquid crystal medium adhere to existing mathematical theorems, physicists at the University of Colorado Boulder have opened the door for the creation of a host of new materials with properties that do not exist in nature. The findings show that researchers can create a "recipe book" to build new materials of sorts using topology, a major mathematical field that describes the properties that do not change when an object is stretched, bent or...


Word of the Day
barghest
  • A goblin in English folklore, often appearing in the shape of a large dog and believed to portend imminent death or misfortune.
  • A ghost, wraith, hobgoblin, elf, or spirit.
The origin of 'barghest' is not known, but it may be from perhaps burh-ghest, town-ghost, or German Berg-geist (mountain spirit) or Bär-geist (bear-spirit).
