General description
4′-Pentyl-4-biphenylcarbonitrile (5CB) is a nematic liquid crystal. 5CB undergoes phase transition from crystalline to nematic then to isotropic state at 18oC and 35oC respectively. It may be produced by modifying biphenyl.2
Application
Attaching 5CB to an aqueous-liquid crystal interface by redox active surfactant has been investigated.

Resistive pressure sensors generally employ microstructures such as pores and pyramids in the active layer or on the electrodes to reduce the Young’s modulus and improve the sensitivity. However, such pressure sensors always exhibit complex fabrication process and have difficulties

Although polycrystalline hexagonal boron nitride (PC-hBN) has been realized, defects and grain boundaries still cause charge scatterings and trap sites, impeding high-performance electronics. Here, we report a method of synthesizing wafer-scale single-crystalline hBN (SC-hBN) monolayer films by chemical vapor deposition.

Two-dimensional liquid-crystal elastomer (LCE) sheets with preprogrammed topological defects are prepared by aligning liquid-crystal monomers within micropatterned epoxy channels, followed by photopolymerization. Upon heating, the LCE films form various three-dimensional structures in agreement with theoretical design. The miniaturized LCE actuators
