2024.102158 The lenses themselves consist of cholesteric liquid crystals, or CLCs. Because CLCs are highly responsive to temperature changes and electric fields, they're used in anti-counterfeit ...
A bistable LCD screen that retains its image without power. Cholesteric LCDs use nematic liquid crystal molecules in a layered, spiral formation (chiral nematic), and power is only required to ...
In 1888, liquid crystals were identified by Austrian botanist Friedrich Reinitzer and German physicist Otto Lehmann. Studying the cholesterol in carrots using a temperature-controlled polarizing ...
The internal structure of LCNPs is characterized by the self-assembly of liquid crystal molecules into ordered domains, such as nematic, smectic, or cholesteric phases, depending on the specific ...
By adding a small amount of a homochiral molecular motor to a unidirectionally aligned cholesteric liquid crystal, the helical organization of the sample is determined. When exposed to ultraviolet ...
