Imaging of director fields in liquid crystals using stimulated Raman scattering microscopy
Taewoo Lee, Haridas Mundoor, Derek G. Gann +2
We demonstrate an approach for background-free three-dimensional imaging of director fields in liquid crystals using stimulated Raman scattering microscopy. This imaging technique…
Optical manipulation of shape-morphing elastomeric liquid crystal microparticles doped with gold nanocrystals
Yaoran Sun, Julian S. Evans, Taewoo Lee +4
We demonstrate facile optical manipulation of shape of birefringent colloidal microparticles made from liquid crystal elastomers. Using soft lithography and polymerization, we fabr…
Active shape-morphing elastomeric colloids in short-pitch cholesteric liquid crystals
Julian S. Evans, Yaoran Sun, Bohdan Senyuk +4
Active elastomeric liquid crystal particles with initial cylindrical shapes are obtained by means of soft lithography and polymerization in a strong magnetic field. Gold nanocrysta…
Reconfigurable interactions and three-dimensional patterning of colloidal particles and defects in lamellar soft media
Rahul P. Trivedi, Ivan I. Klevets, Bohdan Senyuk +2
Colloidal systems find important applications ranging from fabrication of photonic crystals to direct probing of phenomena typically encountered in atomic crystals and glasses. New…
Plasmonic complex fluids of nematiclike and helicoidal self-assemblies of gold nanorods with a negative order parameter
Qingkun Liu, Bohdan Senyuk, Jianwei Tang +4
We describe a soft matter system of self-organized oblate micelles and plasmonic gold nanorods that exhibit a negative orientational order parameter. Because of anisotropic surface…
Nonlinear photoluminescence imaging of isotropic and liquid crystalline dispersions of graphene oxide
Bohdan Senyuk, Natnael Behabtu, Benjamin G. Pacheco +5
We report a visible-range nonlinear photoluminescence (PL) from graphene oxide (GO) flakes excited by near-infrared femtosecond laser light. PL intensity has nonlinear dependence o…
