This paper describes a two phase flow sensor using copper (Cu) thin film electrodes. A two phase flow constitutes a simultaneous flow of two different phases. To identify these phases in an air-water flow in a small diameter tube, Cu films were coated on to glass substrate at various substrate temperatures using dc magnetron sputtering technique. The films were characterized for their structural, morphological and electrical properties using X-ray diffraction (XRD), field-emission scanning electron microscope (FE-SEM) and resistance/capacitance measurement by LCR-Z meter. The grain size of the films increased with increase in the substrate temperature, which in turn reduced the defects. Due to this the resistance of the films decreased. The fabricated capacitor using the Cu film, exhibited different capacitance values with respect to the flow of fluid in the capillary tube.

In the post silicon era as the silicon reaches its fundamental scaling limits graphene nanoribbons is expected to take over and thus continue the Moore's law about the diminishing size of transistors. Graphene nanoribbons facilitates high speed low power switching applications. Low and high field mobilities of the graphene nanoribbons are found to be higher than the CNTs and CMOS keeping the same unit cell. Such properties of graphene nanoribbons are used in the paper to define RAM memory using GNRs as an effective substitute to CMOS and CNTFETs cache memory. Graphene nanoribbon crossbars are used as the basic programmable devices. This 2-D arrangement of GNRs creates programmable diodes at intersection of each horizontal and vertical GNR rod thus opening up new avenues for building high speed memory and digital devices. The graphene nanoribbons based memory is better than the SRAM in terms of speed, density and performance metrics as well. The noise margin of GNR based memory will be .2 volts higher with respect to lower and upper limits than CMOS counterpart used presently as demonstrated by simulations in the paper. GNR based memory would be operating in the 10 nanometres scale and would be 25-50 per cent denser than the existing SRAM.

Bismuth oxide is prepared by a simple chemical route and it crystallizes in the monoclinic crystal system. The measured optical band gap value of 2.694(1) eV supported that the prepared bismuth oxide can be used as a visible light photocatalyst. The degradation property of bismuth oxide is studied using methyl orange as a model pollutant and a degradation of 85% is achieved in 4 h. The kinetics of bismuth oxide is fitted using pseudo first and second order equations.

As the costs for both processing power and memory have reduced, network support for coded video data has diversified, and advances in video coding technology have progressed, the need has arisen for an industry standard for compressed video representation with substantially increased coding efficiency and enhanced robustness to network environments. The H.264/AVC standard aims to enable significantly improved compression performance compared to all existing video coding standards. In this project we employ two schemes of coding transform coefficients namely exponential Golomb coding & context adaptive variable length coding (CAVLC).And the major part of the contribution is the decoding strategy applied for decoding which results in performance enhancement saving the memory and decoding time which are the most important factors for bandwidth utilization. The transform coefficients are obtained using a simple zigzag scan technique. The consensus among the major players of the communications and video industry on H.264 might provide the major thrust for this new standard.

The oxide thickness is of great concern today. The basic idea is to grow SiO2 layer on Silicon. The oxide is grown on intrinsic silicon substrate by thermal oxidation i.e., wet oxidation and dry oxidation. The thickness is compared for both the oxidation processes after different oxidation cycles. The capacitance per unit length is also calculated for the oxide growth in above. The percentage oxide thickness is also estimated and the oxide is found to grow more into the substrate with time and number of cycles.

The effect of water content in anodization of Ti foil on photoelectrochemical activity of TiO2 nanotubes fabricated were studied and optimized. The mixed phase of TiO2 was confirmed from X-ray diffraction and their morphological changes with respect to increase in water content were analyzed using High Resolution Scanning Electron Microscope. The optical band gap of TiO2 can be effectively tuned from 3.023(2) to 2.601(7) eV by varying the water content in anodization. The maximum photocurrent density of 2.5 mA/cm2 was observed for the TiO2 sample with higher crystallinity. These results suggest that the higher crystallinity with ordered nanotubes and lesser band gap act as a key role in improving the photoelectrochemical activity of TiO2.

In this study, sol-gel based ZrO2 nano coating was made on the surface of glazed ceramic tile by spin coating. Further, various surface characteristics were studied after curing at 550°C, 650°C and 700°C, 750°C and 800°C. FTIR, DTA/TG of the gel powder and XRD of calcined gel powder were carried out. The surface of the coating has been characterised using optical microscope and SEM. Properties of coated glazed surfaces such as gloss, colour difference, wetting characteristics and stain resistance were evaluated. Chemical resistance studies (both acid and alkali) of ceramic tiles were also carried out. Experimental results showed that gloss and contact angle of water on the surface of the coated samples significantly increased compared to uncoated substrate. Coated substrates cured at all temperatures exhibited good acid resistance. It has also observed that curing temperature has a strong influence on alkali resistance and coated substrate cured at 650°C and 700°C showed superior alkali resistance than uncoated substrate. In this paper, an effort has been made to explore and validate the potential application of ZrO2 nano coating on the glazed ceramic wall tiles w.r.t improved gloss, hydrophobic properties and chemical resistance.

In this paper the tensile strength and modulus of cow dung powder filled glass- polyester hybrid composites were studied. Two different hybrid composites such as treated and untreated cow dung fibers were fabricated and effect of alkali treatment of the cow dung fibers on these properties were studied. It was observed that, tensile strength and modulus of the hybrid composites increases with increase of cow dung percentage of weight. These properties found to be higher when alkali treated cow dung fibers were used in the hybrid composites. The eradication of amorphous hemi-cellulose with alkali treatment leading to higher crystalline of the cow dung fibers with alkali treatment might responsible for these observations. The effect of alkali treatment on the bonding between glass / cow dung composites was also studied. Scanning electron microscope (SEM) was also conducted on the cross sections of fractured surfaces.

Nanocrystalline SrFe12O19 has been prepared by microwave hydrothermal method at 473 K/90 min, subsequently annealed at different temperatures using microwaves (2.45GHz). The average particle size of the powders was found to be 48 nm. The plate shape grains were observed in FE-SEM at 1073 K. The crystals exhibited the typical hexagonal ferrite growth habit with a plate-like geometry. The effects of microwave sintering temperature on crystallinity, morphology and magnetic properties have been investigated. The grain sizes of sintered hexaferrites are in the range of 250 to 890 nm. The value of Ms = 58 kA/m and Hc = 125 kA/m was obtained at 1173 K/1h.

Solution combustion synthesis technique was adopted to synthesize V2O5, and Mo doped phases, The assynthesized V2O5, has been reduced by a novel reduction technique to form VO2 typephase. The monophasic nature of the samples as revealed by XRD data and systematic shift in peak position indicated solid solubility up to 2 at % of Mo in VO2 lattice. The crystallite size was found to ~ 40 nm. Particle size measurement carried out using Transmission electron microscope (TEM)agreed with XRD experiments. Scanning electron microscope revealed the morphology of the particles to be plate like and bimodal. Variation in the metal-insulator transition temperature as a function of doping was investigated by 4-probe electrical resistivity measurement on sintered ceramics.
