(WILEY-V C H VERLAG GMBH, 1997-01)Ferrimagnetic coupling in a mesogen is reported for the first time for the compound Mn-III[((OC12H25)(4)TPP)](TCNE) . 2 toluene (where TPP = tetraphenyl porphyrin, TCNE = tetracyanoethylene), which displays liquid crystal ...
-
(ELSEVIER SCIENCE BV, 2000-05-12)To clarify the mechanism involved in the appearance of antiferroelectric properties in mixtures of polymers containing achiral mesogenic side chains and their monomers, X-ray investigation was carried out in pyroelectrically ...
-
(AMERICAN PHYSICAL SOC, 2000-01)Thin freely suspended films of a mixture of an achiral side-chain liquid crystal polymer and its monomer have been studied with depolarized reflected light microscopy. We observe that regions with an odd number of bilayers ...
-
(Elsevier, 2020)New therapeutics such as antisense oligonucleotides, small interfering RNA and peptide-drug conjugates are taking great relevance in the pharmaceutical industry due to their specificity of action and their improved safety ...

(WILEY-V C H VERLAG GMBH, 2004-11-04)Ferroelectricity can be defected in systems consisting of liquid-crystal line monomer-polymer mixtures possessing no chiral centers The ferroelectric behavior in mixtures of achiral liquid-crystalline side-chain polymers ...
-
(Taylor & Francis, 2020)The synthesis and phase characterisation of a homologous series of monomers of acrylic phenyl benzoates has been carried out. The characterisation comprises polarised optical microscopy, differential scanning calorimetry ...
-
(Taylor & Francis, 2017)We explore the possibility of producing polymer nanocomposites with an ordered distribution of nanoparticles by using an electropolymerizable liquid crystal (LC) monomer. The nanoparticles are added to the monomer before ...
-
(MDPI, 2020)Purified walnut oil (PWO) microparticles with Capsul(R) (C, encapsulating agent), sodium alginate (SA) as outer layer and ascorbic acid (AA) as oxygen scavenger were obtained by spray drying using a three-fluid nozzle. AA ...
-
(Universidad de Chile, 2014)Se estudiaron mezclas de tres monómeros líquidos cristalinos con fullereno: dos de ellos son azo compuestos A6OA12 y A6A12, y el tercero una imina, A11R6. No se apreció una buena miscibilidad entre dichos compuestos y ...
-
(GORDON BREACH SCI PUBL LTD, 2000)In this paper we report on the synthesis and characterization of new mixtures of achiral liquid crystalline side-chain polymers with their monomers. The samples have a basic structure similar to materials prepared earlier ...
-
(Royal Soc Chemistry, 2015)A small fraction of an acrylate liquid crystalline monomer (<= 5%) is mixed into nematic and smectic liquid crystalline phases, and polymerised through the application of a voltage (electropolymerisation). Polarising ...
-
(Pleiades Publishing, 2015)In this study, we compare the results of experimental investigations of longitudinal and transverse pyroelectric effects in a chiral ferroelectric crystal. In a transverse geometry, we studied freely suspended liquid-crystal ...
-
(GORDON BREACH SCI PUBL LTD, 1995)In this contribution, magnetic investigations on materials, which essentially combine mesogenic and polymeric properties, were presented. In the glassy and the smectic phase of a copper(II) containing polymer we observed ...
-
(TAYLOR & FRANCIS LTD, 1996-01)A synthetic route has been developed to a new series of homo- and co-polysiloxanes with a terminal chiral 2-(S)-butyl fragment attached to the mesogenic biphenyl core via the ketone binding group, >C=O. The synthesis, ...
-
(TAYLOR & FRANCIS LTD, 2004-08)The synthesis and phase characterization of three homologous series of liquid crystalline acrylic and methacrylic monomers, consisting of 21 new compounds are presented. They are based on omega-hexyloxy- and omega-undecy ...
-

-
(Royal Soc Chemistry, 2015)We synthesized monomeric liquid crystals, M6R8 and I6R8, and nanoparticles of TiO2, to form a nanocomposite, which was characterized by polarized optical microscopy (POM), DSC and structurally by both wide angle X-ray ...
-
(Taylor & Francis, 2016)The synthesis and phase characterisation of two homologous series of monomers of acrylic azo-compounds has been presented. The characterisation comprises polarising optical microscopy (POM), differential scanning calorimetry ...
