Autor: Joel Pendery, Juan J. de Pablo, Uma Sridhar, Nicholas L. Abbott, Sankaran Thayumanavan, Young-Ki Kim, Piyachai Khomein, Krishna R. Raghupathi

Publikováno v: Langmuir. 34:10092-10101

We report an investigation of the influence of aqueous solutions of amphiphilic oligomers on the ordering of micrometer-thick films of thermotropic liquid crystals (LCs), thus addressing the gap in knowledge arising from previous studies of the inter

Design Principles for Triggerable Polymeric Amphiphiles with Mesogenic Side Chains for Multiscale Responses with Liquid Crystals

Autor: Joel Pendery, Nathan C. Gianneschi, Jiawei Sun, Lisa Adamiak, Nicholas L. Abbott, Kazuki Iwabata

Publikováno v: Macromolecules. 51:1978-1985

Interfacial assemblies formed by polymeric amphiphiles at aqueous interfaces of thermotropic liquid crystals (LCs) can trigger multiscale changes in the organization of the LCs in response to recognition events. However, we have a limited understandi

Amphiphile-Induced Phase Transition of Liquid Crystals at Aqueous Interfaces

Autor: Joel Pendery, Young-Ki Kim, Benoît Roux, Sankaran Thayumanavan, Mohammad Rahimi, Juan J. de Pablo, Hadi Ramezani-Dakhel, Nicholas L. Abbott

Publikováno v: ACS applied materialsinterfaces. 10(43)

Monolayer assemblies of amphiphiles at planar interfaces between thermotropic liquid crystals (LCs) and an aqueous phase can give rise to configurational transitions of the underlying LCs. A common assumption has been that a reconfiguration of the LC

Physical Review E, American Physical Society (APS), 2017, 96 (1), pp.012706. ⟨10.1103/PhysRevE.96.012706⟩

International audience; A long time ago, Brochard and de Gennes predicted the possibility of significantly decreasing the critical magnetic field of the Fredericksz transition (the magnetic Fredericksz threshold) in a mixture of nematic liquid crysta

Straining soft colloids in aqueous nematic liquid crystals

Autor: Saverio E. Spagnolie, Joel Pendery, Peter C. Mushenheim, Nicholas L. Abbott, Douglas B. Weibel

Liquid crystals (LCs), because of their long-range molecular ordering, are anisotropic, elastic fluids. Herein, we report that elastic stresses imparted by nematic LCs can dynamically shape soft colloids and tune their physical properties. Specifical

A polyimide substrate was scribed using the stylus of an atomic force microscope, then covered with a nematic liquid crystal. The fiber from a near field scanning optical microscope was immersed into the liquid crystal and rastered approximately 80 n

International audience; We show that the study of gold nanoparticle self-assemblies induced by a liquid crystal matrix reveals the intimate distorted structure of the liquid crystal existing prior to nanoparticles incorporation. We also show how this

Macroscopic torsional strain and induced molecular conformational deracemization

Autor: Charles Rosenblatt, Rajratan Basu, Joel Pendery, Robert P. Lemieux, Rolfe G. Petschek

Publikováno v: Physical review letters. 107(23)

A macroscopic helical twist is imposed on an achiral nematic liquid crystal by controlling the azimuthal alignment directions at the two substrates. On application of an electric field the director rotates in the substrate plane. This electroclinic e

Publikováno v: Physical review letters. 104(25)

A substrate coated with an achiral polyimide alignment layer was scribed bidirectionally with the stylus of an atomic force microscope to create an easy axis for liquid crystal orientation. The resulting noncentrosymmetric topography resulted in a ch

A nematic twist cell having a thickness gradient was filled with a mixture containing a configurationally achiral liquid crystal (LC) and chiral dopant. A chiral-based linear electrooptic effect was observed on application of an ac electric field. Th
