CdS decorated ZnO nanorods have been grown by a combination of hydrothermal method and successive ion layer absorption and reaction (SILAR) method. Optical absorption and emission properties of ZnO nanorods have been studied after sensitization with CdS nanoparticles. Current-voltage characteristics of ZnO nanorods and CdS sensitized ZnO nanorods have been(More)
A detailed comparative study of the dielectric and electro-optical properties of a ferroelectric liquid crystal (FLC) and FLC after having doped with conducting polymer Poly (3,4-ethylenedioxythiophene) (PEDOT) nanotubes is done. The electro-optic study reveals a lower electrical response time, rotational viscosity and spontaneous polarization in the(More)
The optimum method of equalisation for channels with multi-path propagation is maximum likelihood sequence estimation (MLSE) using Viterbi algorithm. This algorithm, however, has exponential complexity that makes it unsuitable for use in channels with large delay spreads as is typical in wireless MAN scenarios. Here, we propose an alternative to the basic(More)

A simple, rapid, and sensitive high-performance liquid chromatographic method with UV detection has been developed and validated according to the ICH guidelines for the quantization of Ceftriaxone (CEF) and Sulbactam (SUL) in parenteral preparation. Chromatographic separation was carried out in a Hypersil Gold C8 column (250 mm × 4.6 mm; 5 μm particle size)(More)
A multistage field emitter based on graphene-linked ZnO nanowire array is realized by means of spin-coating a graphene dispersion (reduced graphene oxide) over a nanostructured platform followed by plasma modification. Spin-coating leads to interlinking of graphene sheets between the neighboring nanowires whereas plasma etching in the subsequent step(More)
Large scale high yield cadmium sulfide (CdS) nanowires with uniform diameter were synthesized using a rapid and simple solvo-chemical and hydrothermal route assisted by the surfactant cetyltrimethylammonium bromide (CTAB). Unique CdS nanowires of different morphologies could be selectively produced by only varying the concentration of CTAB in the reaction(More)
