Researchers at CU Boulder’s Soft Materials Research Center (SMRC) have discovered an elusive phase of matter, first proposed more than 100 years ago and sought after ever since.

The team describes the discovery of what scientists call a “ferroelectric nematic” phase of liquid crystal in a study published today in the Proceedings of the National Academy of Sciences. The discovery "opens a door to a new universe of materials," said co-author Matt Glaser, a professor in the Department of Physics.

[...] The researchers ran more tests and discovered that this phase of RM734 was 100 to 1,000 times more responsive to electric fields than the usual nematic liquid crystals. This suggested that the molecules that make up the liquid crystal demonstrated strong polar order.

“When the molecules are all pointing to the left, and they all see a field that says, ‘go right,’ the response is dramatic,” Clark said.

[...] When the researchers examined how well aligned the molecules were inside a single domain, “we were stunned by the result,” MacLennan said. The molecules were nearly all pointing in the same direction.

    No, it was Phase 3: Profit!

    They didn't discover it until now because it requires that you buy the absolute latest smart phone first.
