(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 B. V., 1996)X-ray structure determination and pyroelectric measurements have been carried out on mesogenic mixtures composed of an achiral side-chain polymer and its monomer. The mixtures show antiferroelectric polarization hysteresis ...

(2007)Ferroelectric liquid crystals bearing a chiral pyrrolidine-type ring were prepared using (-)-(S)-malic acid as a building block. The compounds were characterized using the thermal analysis techniques of DSC and POM, ...
-
(TAYLOR & FRANCIS LTD LONDON, 1995-02)The behaviour of a large number of paramagnetic metallo-mesogenic molecules with Cu and VO in different mesophases in a magnetic field was investigated by EPR techniques and magnetic susceptibility measurements. The ...
-
(2012)The synthesis of one homologous series of methacrylate monomers and their polymers was carried out to observe the dependence between the polarization and some structural aliphatic features. Investigations of the thermoanalytical, ...

Effect of adding curcumin on the properties of linseed oil organogels used as fat replacers in pâtés (MDPI, 2020)Beeswax-based organogels were formulated with linseed oil and curcumin according to a statistical design to increase the oxidative stability of spreadable meat products (pate) where these organogels (OGCur) were incorporated ...
-
(MDPI AG, 2018)Photoluminescent mechanisms in erbium-doped barium titanate nanoparticle systems were studied. Er3+ ions were introduced into the BaTiO3 lattice by the sol-gel method. The resulting Er3+ concentration was between 0% and ...
-
(ROYAL SOC CHEMISTRY, 2012)Five copolymers were prepared by polymerization of azo-benzene methacrylate monomers in solution using AIBN as initiator. The mesophases were observed by a polarizing light microscope which showed tilted smectic C phases ...
-
(2009)This paper describes the synthesis and characterisation of methacrylic liquid crystalline side chain polymer containing azo group, with (PM6OAn) and without (PM6An) hydroxyl group. The characterisation was done by using a ...

(Elsevier B.V., 2019)We have studied the effect of a static external electric field on electronic properties of methyl methacrylate (MMA) and its consequences in an electro-initiated polymerization by density functional theory (DFT). The ...
-
(2008)Novel liquid crystalline materials based on chiral calamitic 1,2,4- and 1,3,4-oxadiazole derivatives were synthesized and their thermotropic mesomorphism investigated by polarizing optical microscopy and differential ...
-
(2010)We show both theoretically and experimentally that passive amplification of the pyroelectric current takes place when modulated radiation is recorded by a pyroelectric detector in some range of modulation frequencies. The ...
