Gold nanorods embedded discotic nanoribbons
(2013)It is shown that gold nanorods (GNRs) can be easily inserted into the supramolecular order of discotic liquid crystals (DLCs) along the director without disturbing their mesomorphism. GNRs embedded discotic nanoribbons, ... -
Degeneracy lifting due to thermal fluctuations around the frustration point between anticlinic antiferroelectric SmCA* and synclinic ferroelectric SmC*
(2013)In the binary mixture phase diagram of MC881 and MC452, the borderline between anticlinic antiferroelectric SmC?A and synclinic ferroelectric SmC? becomes apparently parallel to the temperature ordinate axis at the critical ... -
Field-induced periodic chiral pattern in the Nx phase of achiral bimesogens
(2012)Some hydrocarbon-linked mesogenic dimers are known to exhibit an additional nematic phase (Nx) in the temperature range below the conventional nematic (Nu) phase. One of the features of this phase is the presence of optical ... -
Chirality of an achiral bent-core nematic mesogen observed in planar and homeotropic cells under certain boundary conditions
(2012)It is shown that planar and homeotropic cells under certain boundary conditions containing an achiral bent-core C5 liquid crystalline material show chiral domains of opposite handedness. However such domains are not seen ... -
Biaxial order and a rotation of the minor director in the nematic phase of an organo-siloxane tetrapode by the electric field
(2012)Biaxiality in the nematic phase for a liquid crystalline tetrapode made up of organo-siloxanes mesogens is investigated using polarized infrared spectroscopy. An ordering of the minor director for the homeotropically aligned ... -
Development of polar order in a bent-core liquid crystal with a new sequence of two orthogonal smectic and an adjacent nematic phase
(2011)A 4-cyanoresorcinol based bent-core liquid crystal shows a new phase sequence of two orthogonal smectic phases with short range (SmAP R) and long range (SmAP A) polar order beside a SmA-type cybotactic nematic phase (N ... -
Effect of high hydrostatic pressure on the dielectric relaxation in a non-crystallizable monohydroxy alcohol in its supercooled liquid and glassy states
(2011)The complex relative permittivity of a non-crystallizable secondary alcohol, 5-methyl-2-hexanol, is measured over a wide range of temperatures and pressures up to 1750 MPa (17.5 kbar). The data at atmospheric pressure (P ... -
Debye process and dielectric state of an alcohol in a nonpolar solvent.
(2011)To investigate the origin of the first order molecular kinetics of the most prominent, Debye-type polarization, a detailed dielectric relaxation study of 66.5, 40, and 20 mole solutions of 5-methyl-2-hexanol in 2-methylpentane ... -
Liquid crystal display modes in a nontilted bent-core biaxial smectic liquid crystal
(2010)Liquid crystal display (LCD) modes associated with the rotation of the secondary director in nontilted, biaxial smectic phase of an achiral bent-core compound are demonstrated. For LCDs, we find that at least four display ... -
A Compact Shorted Printed Monopole Antenna for TV White Space Trials
(2013)This paper presents a compact shorted printed monopole antenna for machine-to-machine, remote sensing and rural wireless applications in the TV whitespace band from 470 MHz to 862 MHz. The antennas performance in this ... -

Dual Band LTE Planar Inverted-F Antnna for M2M Applications
(2013)A Planar Inverted-F Antenna for M2M applications is presented. The antenna is located on a rectangular ground plane and operates across both LTE frequency bands (690-960 MHz) and (1710-2690 MHz). The low cost antenna has ... -
Surface Tamm states in a photonic crystal slab with asymmetric termination
(2013)The reflection and transmission spectra of a finite thickness 2D Photonic Crystal Slab (PCS) based on macroporous silicon are investigated. Periodic photonic crystal region is separated from air by homogeneous silicon ... -
ON THE STABILITY OF TWO-DIMENSIONAL DISCRETE-SYSTEMS - COMMENT
(ISI Web of Science, 1981)This correspondence shows that independent necessary conditions and sufficient conditions for the asymptotic stability of two-dimensional discrete linear systems presented by Ahmed can be readily obtained from previous results. -
Thermal fluctuations of magnetic nanoparticles: fifty years after Brown
(2012)The reversal time, superparamagnetic relaxation time, of the magnetization of fine single domain ferromagnetic nanoparticles owing to thermal fluctuations plays a fundamental role in information storage, paleomagnetism, ... -
Dynamic Block-Edge Masks (BEMs) for Dynamic Spectrum Emission Masks (SEMs)
(2010)This paper explores the evolving role of transmitter spectrum masks in the emerging paradigm of service and technology neutral spectrum planning. We advocate the use of more dynamic approaches to spectrum mask generation ... -
Exclusive Sharing & Virtualization of the Cellular Network
(IEEE, 2011)The focus of this paper is to progress a discussion about the redefinition of what it means to be a cellular network operator. Alternative modes of ownership may allow for the creation of more flexible cellular networking ... -
Enhancement of photoluminescence signal from ultrathin layers with silicon nanocrystals
(2012)Using the model of oscillating dipoles, we simulated the photoluminescence intensity of a triple-layered structure where the silicon nanocrystals layer was enclosed by buffer and capping silicon dioxide layers. It was ...
