Self-assembly of novel ureido dipeptide esters and investigation of its gelation property
(Indian Journal of Biochemistry & Biophysics, 2025) Ranade, Prasanna
Ureido group is an interesting moiety as hydrogen donor and acceptor functionalities are present. Peptides are intriguing molecules as their properties are easily tuned and they are biocompatible. Therefore, four ureido dipeptide esters were synthesized using simple solution phase synthesis and characterized. Their biological activity was investigated against Streptococcus pyogenes, Staphylococcus aureus and E. coli. A rheological study was carried out to study the gelation properties of the synthesized compounds. Their ability to self-assemble into different morphologies was studied using SEM. The morphology of cubes, sheets, spheres, and rods was observed in the SEM study. These compounds will have potential applications in the medicinal field as drug delivery vehicles.
Study of PDCLC Materials Using Fabry Perot Scattering Technique
(Journal of Optics, 2007) Kanwar, Anita
Polymer dispersed cholesteric liquid crystals (PDCLCs) consist of liquid crystal (nematic and Cholesteric) droplets that are dispersed in a solid polymer matrix. PDCLCs are a relatively new class of materials that hold promise for many applications ranging from switchable windows to projection displays. These materials, which are simply a combined application of polymers and liquid crystals, are the focus of extensive research in the display industry. Cholesteric liquid crystasls are often considered to exhibit a modified nematic phase, the molecules they contain being parallel, but characterized by a continual rotation of the direction of molecular alignment (Director). This unusual twisting often causes the appearance of bright colors when cholesteric liquid crystals diffract light [1]. The mixtures of PDCLCs with room temperature nematic liquiod crystal TL205 doped with Cholesteryl materials having different liquid crystal concentrations and polymer PN393 were investigated. The concentration of cholesteric liquid crystal played crucial role in the properties of PDCLCs. The phase transition temperatures (PTTs) of the samples thus prepared were studied using Fabry Parol scattering studies (FPSS), Optical Polarising Microscope (OPM) and Differential Thermal Analysis (DTA).
Temperature Stablised LED and LD Drive Circuits
(Journal of Optics, 2008) Kanwar, Anita
The Light emitting diode (LED) and Laser Diode (LD) drive circuits for optical fiber communication transmission systems are very sensitive to the variations in temperature as forward current increases and diode junction voltage decreases leading to the poor spectral and circuit stability of the LED and LD drive circuits can be improved by designing the circuits for the two temperature ranges and the circuits analysed in these stability conditions. The performance of such circuits is better than any other design technique.
Study of PDLC and PDCLC mixtures using various techniques
(Journal of Optics, 2008) Kanwar, Anita
Polymer Dispersed Liquid Crystal (PDLC) and Polymer Dispersed Cholesieric Liquid Crystal (PDCLC)fdms were prepared by thermal-induced phase separation method. PDLC and PDCLC films are analyzed using Fabry Parol Scattering Studies (FPSS), Differential Thermal Analysis (DTA) and Fourier Transform Infra-red (FTIR) Spectroscopy. Changes in the structure, phase transition temperatures (PTTs) and clearing temperatures i.e. the temperature at which the material becomes isotropic are listed. FTIR spectrometer is used to find the structural changes due to the addition of cholesteric material to PDLC. DTA technique is used to corroborate the results obtained using the FPSS technique. Present studies reveals that the PDCLC samples are a homogeneous mixture at the room temperature. Transmission intensity and hence the homogeneity of the samples is seen to be maximum for the PDCLC sample containing 80% (80% TL205+20% Cholesteryl Pelargonate) + 20%PN393. Approximate range of percentage transmission decreases as the concentration of the cholesteric material increases.
Studies of Nano-Particle Doped Liquid Crystal Mixtures
(Molecular Crystals and Liquid Crystals, 2009) Kanwar, Anita
Liquid crystals (LCs) are rod-shaped molecules which can diffuse freely like liquid and orient themselves under the influence of electric field with the long axis of molecules pointing in the same direction. Carbon nanotubes and bucky balls are ideal LC dopants because of their strength, conductivity, flexibility and novel electrical characteristics. LCs doped with C60 show enhancement of the director axis reorientation and enhancement of its nonlinear optical properties. Refractivity of LCs can also be altered by doping nanoparticles and/or nanotubes. In this paper, the effect of the presence of nanoparticles/nao-tubes on the phase transition temperatures of the LCs and the classification of the mesophases so formed are investigated by us with the help of the textures studied under the polarizing micro-scope. The phase transition temperatures as well as the heats of transition of the doped LCs using various techniques are also presented.
