Dynamic Motions of Topological Defects in Nematic Liquid Crystals under Spatial Confinement
Article discusses how topological defects (TDs) have become a sensational topic due to their significant influence on the unusual optical and physiochemical characteristics of the material. Here, authors assert how nematic liquid crystals confined in a cell exhibiting surfaces with periodic anchoring conditions containing surface topography are relied on.

Carrier photodynamics in 2D perovskites with solution-processed silver and graphene contacts for bendable optoelectronics
Article reporting on the inkjet printed, direct contact study of solution-processed, 2D perovskite-based photodetectors (PDs) formed on flexible PI substrates. Silver (Ag) and graphene (Gr) inks have been engineered to serve as efficient electrical contacts for solution-processed two-dimensional (2D) organo-halide (CH3(CH2)3NH3)2(CH3NH3)n−1PbnI3n+1 (n = 4) layered perovskites, where all inkjet-printed heterostructure PDs were fabricated on polyimide (PI) substrates.

Light Confinement in Twisted Single-Layer 2D+ Moiré Photonic Crystals and Bilayer Moiré Photonic Crystals
Article reporting optical properties of twisted single-layer 2D+ moiré photonic crystals where there is a weak modulation in z direction, and bilayer moiré-overlapping-moiré photonic crystals. This study leads to a potential application of 2D+ moiré photonic crystal in future on-chip optoelectronic integration.
