This disrupts the orientation of the liquid crystal molecules.

For example, a colloid in the shape of a sphere will cause the liquid crystal molecules to align perpendicular to the surface of the sphere, a bit like a hedgehog's spikes.

By adding different liquid crystal molecules, Khandelwal was able to block nearly 100 % of the sunlight between 700 nm and 1400 nm, yet the transparency of the visible light was still around 90 %, comparable with the transparency of double glazing.

When an electric voltage reorients the liquid crystal molecules, the light is no longer twisted and can't exit.

To make the liquid crystal molecules in each cell stack up in the staircase - like fashion, displaymakers rub the two plastic layers that sandwich them in perpendicular directions with a velvet roller.

Not exact matches

The forces holding diiodine molecules in the crystal are modest, and liquid iodine is not stable at ordinary temperatures and pressures, so that solid iodine sublimes to give a rather large concentration of diatomic molecules in the vapor phase.

Unlike conventional liquid crystals where electrical connections on the plates create the fields required to switch individual pixels from light to dark, optically rewritable LCDs coat the plates with special molecules that realign in the presence of polarized light and switch the pixels.

When an electric current is turned on, the liquid - crystal molecules rotate, thus bending the incoming light like a lens.

These antifreeze molecules lock onto ice crystals, but not liquid water — though how they do this has been a mystery.

This aligns the plastic molecules and causes the liquid crystals near them to line up in the same direction; with the liquid crystals on either side now stacked perpendicular to one another, the ones in between automatically form the staircase.

Unlike the particles in a coffee drop, the liquid crystal drop they studied was a solution of Sunset Yellow molecules that spontaneously combine to form rod - like macromolecular assemblies, similar to how rod - like molecules order to form the liquid crystals used in LCDs.

While the liquid crystals used in LCDs, called thermotropic liquid crystals, are made of molecules with nothing else added, the liquid crystals used in this experiment were chromonic liquid crystals.

Organofluorine molecules are also used in liquid crystals for displays, as well as ozone - friendly refrigerants and propellants.

But liquid crystals are relatively slow: Each molecule must entirely change orientation to alter how it interacts with light, to change color or show a new image on a screen, for instance.

These particles were coated in an organic compound designed to disturb the order of the surrounding liquid - crystal molecules and cause them to align themselves perpendicular to the surface of each sphere.

To investigate microscopic knots, Tkalec and colleagues turned to liquid crystals, which flow like fluids but whose constituent molecules line up in the same direction, like a solid crystal.

«A lot of the work that is done to understand these types of liquid crystal systems,» Collings said, «is to put two competing influences on them, such as the molecules» natural tendency to line up perfectly versus some confinement or external field that says, «We're not going to let you do that.»»

In a liquid - based process, solvent molecules can be inserted into the host materials along with guest ions, degrading the crystal quality.

In a conventional LCD, applying an electric field to the liquid crystal makes the molecules line up in such a way that they shift the polarisation of light through 90 degrees.

When an icy impact occurred, the impactor's kinetic energy became heat energy, instantly melted some ice, gouged out a crater, and kicked up into Mars» thin atmosphere large amounts of debris mixed with water (liquid, ice crystals, and vapor)-- and complex organic molecules that obviously came recently from life.127 Then, the dirt and salt - water mixture settled back to the surface in vast layers of thin sheets — strata — especially around the crater.

The way the e-paper, which uses a flexible cholesteric liquid crystal panel, works is this: The basic principle is that this material holds a very similar structure to the biological cholesterol molecules from which the e-paper has got its name 12Re - Paper.

A thermal printer fitted with a thermal head requiring 86 °C (186.8 °F) in temperature and just 37W of power heats the liquid - crystal layer, turning molecules light or dark.

These models are based on the assumption that the particle's (atom, molecule, or cluster) transition from the higher energetic level (vapor or liquid) to a lower one (liquid or crystal) produces an emission of one or more photons.

Unlike most liquids, which shrink when cooled, water molecules align and freeze in a spaced out crystal lattice.
