TL;DR: In this paper, the phase transition behaviors of the rod-disc molecule (RD12, where 12 is the number of carbon atoms in each alkyl chain linkage between the rod and the disc mesogens) were dramatically changed upon varying the thickness of liquid crystal cells and alternating their surface chemical and physical environments.

TL;DR: P polarized optical microscopy is reported to observe defect distributions in monolayer graphene and shows that point defects generated by prolonged UV irradiation time give rise to irregular LC alignment with disclination lines on the graphene surface and a large-size LC domain associated with graphene single domain eventually disappeared, indicating that defects associated with oxygen-containing functional groups cause to reduce the strong stacking interaction between graphene and LC molecules.

TL;DR: In this article, the authors used inorganic salt to control the resistivity of the in-plane switching (IPS) alignment layer and found that this approach reduced DC image sticking without any loss of reliability property in IPS-LCD.

TL;DR: In this paper, the electrochemical properties such as self-discharge, leakage current and voltage holding tests (VHTs) of reduced graphene oxide (RGO) based solid-state symmetric supercapacitors (SSCs) were reported.

TL;DR: In this article, a high-efficiency and fast-switching phase grating based upon a polymer-stabilized liquid crystal device driven by in-plane switching electric field is demonstrated.
