Liquid crystal

WORM displays can be imprinted with words or pictures using UV light (Photo: UMP)

Scientists at Universiti Malaysia Pahang (UMP) have developed displays that can be written on and erased with light. The WORM (Write Once Read Many) display is an optical storage device whose molecular geometry can be altered by shining light on it, allowing information in the form of words or pictures to be impressed on it in as little as 20 seconds. The environmentally-friendly display is also easy to dispose of, the researchers report, as users only have to scratch its surface to remove its protective coating and dip it in water to dissolve it.  Read More

The parallel ordering of liquid crystals make them near-frictionless lubricants (Image: Mi...

The world uses tens of millions of tons of lubricant every year, from the smallest part of a micro-precision instrument to the expansion rollers on the largest bridges. Most are oil based, though others use powders, and even metals, and it’s been that way for decades. That could be changing as the Fraunhofer Institute for Mechanics of Materials, Nematel GmbH, and Dr. Tillwich GmbH have developed a new class of lubricants that are based on liquid crystals instead of oil. According to Fraunhofer, this is the first fundamentally new lubricant developed in twenty years.  Read More

Patterns created by bacteria swimming through the living liquid crystal

With any medical condition, the earlier it's detected, the better the chances are of successfully treating it. When assessing biological samples from a patient, however, it's often quite difficult to see the indicators of a disease when it's still in its early stages. That could be about to change, thanks to the development of a solution known as "living liquid crystal."  Read More

A liquid crystal 'flower' under magnification (Photo: University of Pennsylvania)

Scientists at the University of Pennsylvania have grown liquid crystal flowers, making it possible to create lenses as complex as the compound eye of a dragonfly. When perfected, the technology could allow the growth of lenses on curved surfaces, and structures to be assembled out of liquid crystals to build new materials, smart surfaces, microlens arrays and advanced sensors.  Read More

Stealth LCD monitor showing a Rubik's cube through polarizing sunglasses (Photo: Brusspup)

An additional layer of security (and fun) can be added to your computer's LCD display by following the lead of Brusspup, a well-known online illusionist and computer artist. Just remove your display's outer polarizing filter, and use polarizing sunglasses instead.  Read More
