Thermotropic liquid crystals (LCs) present opportunities for synergistic interactions with ligand-functionalized nanoparticles (NPs). Understanding the dynamics and structures of ligand-coated NPs in an anisotropic LC environment allows better design control versatile LC-NP hybrid materials. Here, simulations experiments yield direct evidence that cyanobiphenyl LCs induce anisotropy biphenylalkyl ligand shells spherical NPs. The ellipsoidal NP aligns director. Magnetic fields can dictate...
Microdroplets made from chiral liquid crystals (CLCs) can display reflective structural colors. However, the small area of reflection and their isotropic shape limit performance. Here, Janus microdroplets are synthesized through phase separation between CLCs silicone oil. The as-synthesized show primary colors with ≈14 times larger compared to spherical counterparts at a specific orientation; orientation thus colored/transparent states be switched by applying magnetic field. color tuned...
The size-dependent and collective physical properties of nanocrystals (NCs) their self-assembled superlattices (SLs) enable the study mesoscale phenomena design metamaterials for a broad range applications. However, limited mobility NC building blocks in dried NCSLs often hampers potential employing postdeposition methods to produce high-quality NCSLs. In this study, we present tailored promesogenic ligands that exhibit lubricating property akin thermotropic liquid crystals. ability is...
The growth of superlattices (SLs) made from self-assembled nanocrystals (NCs) is a powerful method for creating new materials and gaining insight into fundamental molecular dynamics. Previous explorations NCSL syntheses have mostly compared them to crystallization. However, synthesis has not broadly shown cooling crystallization saturated solutions as reversible crystallization-dissolution process. We demonstrate the NCSLs by dispersing NCs in liquid crystal (LC) "smart solvents," harnessing...
Emerging applications of Internet Things (IoT) technologies in smart health, home, and city, agriculture environmental monitoring, transportation manufacturing require materials devices with engineered physical properties that can be manufactured by low-cost scalable methods, support flexible forms, are biocompatible biodegradable. Here, we report the fabrication device integration biocompatible/biodegradable colloidal Cu nanocrystal (NC) films through room temperature, solution-based...
Liquid crystal-nanoparticle (LC-NP) hybrid systems allow synergistic interactions between LC matrixes with anisotropic alignment and NP dopants versatile functionalities. A uniform, well-dispersed, highly stable thermotropic LC-NP mixture paves the way for further applications. In this work, a linear promesogenic ligand two types of dendritic ligands alkyl or oligo ethylene glycol (OEG) chains are designed synthesized to facilitate incorporating NPs into 4-cyano-4′-pentylbiphenyl (5CB)...
A planetary thread roller bearing (PTRB) is a state-of-the-art component in electromechanical actuators (EMA) due to its high load-bearing capacity and small volume. The study of the PTRB leading task domain EMA application. In this study, we propose mathematical model friction torque on working principle causes. Specifically, impact basic properties torque, i.e., rotating speed external load, are modeled analyzed. To verify variation experiments carried out an actual PTRB. For test PTRB,...
