Photocatalytic degradation of malachite green using PVDF membranes doped with Fe<sub>3</sub>O<sub>4</sub> nanoparticles: role of porosity and surface roughness Open
We report on a cost-effective and time-efficient approach to synthesize flexible membranes of polyvinylidene fluoride (PVDF) doped with varying concentrations of Fe 3 O 4 nanoparticles (FNP). The membranes exhibit a uniform dispersion of F…

Thermo-Chromic Response of Polymer Stabilized Cholesteric Liquid Crystal for Thermal Imaging Open
Cholesteric liquid crystal (Ch-LC) exhibits many remarkable optical properties due to formation of a macroscopic helical structure. A low amount of monomer (5wt.%) is dispersed into cholesteric liquid crystal and get polymerized under UV r…

Growth and analysis of highly oriented (11n) BCSCO films for device research Open
Films of BCSCO superconductor of the type Bi{sub 2}CaSr{sub 2}Cu{sub 2}O{sub x} have been grown by liquid phase epitaxy method (LPE), using a partially closed growth chamber. The films were grown on (001) and (110) NdGaO{sub 3} substrates …

Experimental and neural network approach to effective electrical conductivity of carbon nanotubes dispersed chiral nematic liquid crystals Open
Single walled carbon nanotubes (SWCNT’s) doped cholesteric liquid crystal composite has been prepared and characterized for their electrical responses. Also theoretically, an artificial neural network (ANN) approach has been trained for…

Structural, dielectric and conductivity behaviours of cetyltrimethylammonium bromide/ethylene glycol-based quenched lyotropic mesophases Open
The present study highlights the effect of quenching on the structural, textural and dielectric dynamics of cetyltrimethylammonium bromide/ethylene glycol binary mixtures of varying concentrations 30:70, 50:50 and 75:25 wt.%. No mesomorphi…

Effect of quenching on the structural and dynamic properties of non-aqueous lyotropic mesophases Open
We focused to highlight the effect of quenching on the development and ordering of non-aqueous lyotropic liquid crystalline phases. Lyotropic mesophases are prepared from binary mixtures of sodium dodecyl sulphate and ethylene glycol at va…
