And, like
the liquid crystals found in displays, this state can be influenced by external effects, and the resulting behavior may be harnessed for applications.
In a study published in the Proceedings of the National Academy of Sciences, researchers from the University of Pennsylvania and Swarthmore College describe new research into a type of liquid crystal that dissolves in water rather than avoids it as do the oily
liquid crystals found in displays.
Unlike
the liquid crystals found in displays, the phases or patterns formed by lyotropic liquid crystals are dependent on their concentration.
Most oil - based
liquid crystals found in displays respond to this kind of confinement similarly in that they form a central axis with two poles, but differently in that they don't twist away from that axis.

The researchers tried three different spacer designs and
found that a meshlike spacer prevented
liquid crystal from flowing when their LCD was bent or hit.
The
crystals contained tiny pockets of
liquid, and the team
found that they could grow live colonies of archaeans from samples of it.
When the
liquid is applied to a flexible base such as plastic, the solvent evaporates, leaving the
crystal nano - particles — the very same semiconductors
found in everyday chips — to form structures capable of conducting electricity.
For example, scientists have
found signs of
liquid water and even faint hints of possible life in zircon
crystals dating back 4.1 billion years (SN: 11/28/15, p. 16).
Liquid crystals are remarkable materials that combine the optical properties of crystalline solids with the flow properties of
liquids, characteristics that come together to enable the displays
found in most computer monitors, televisions and smartphones.
One of the only previously observed apparent quantum spin
liquids occurs in a natural
crystal called herbertsmithite, an emerald green stone
found in 1972 in a mine in Chile.
A common type of screen technology,
found in laptops at the time, resembles a sandwich, with two sheets of glass as the bread — one on top, one on the bottom — and
liquid crystals as the sandwich filling.
