If DNA nanotechnology is to become a viable technology for therapeutics, diagnostics or life science research, the component materials mostly single stranded DNA will have to be produced cheaply, abundantly and with very high quality. Prior experiments demonstrated the production of clonal template through perfectly controlled relative stoichiometric ratios in a highly scalable enzymatic process called the MOSIC method (Monoclonal StoichiometrIC). To assess whether the technique for the production of oligos enzymatically could be useful in more applications in DNA nanotechnology, a pseudogene coding a crystal template was produced using helper phages in this project. This method enables the production of such single stranded DNA with high yield, low cost and easily scalable method.

The dye, acid blue 113, was degraded photo catalytically by using ZnO nano particles under visible light irradiation in a continuous flow reactor. ZnO nano particles were synthesized by Sol-gel process and it was characterized by SEM, EDX, XRD, and BET analysis. The prepared ZnO nano particles were effectively used for the photo degradation of acid blue 113. The effect of various operational parameters such as pH, concentration and flow rate was carried out. It was found that the maximum dye degradation occurred at 50 μM at pH 7. The optimum flow rate was observed at 11.7 ml/min for 2g of the catalyst.

Segmentation of images holds an important position in the area of image processing. Computer aided detection of abnormality in medical images is primarily motivated by the necessity of achieving maximum possible accuracy. There are lots of methods for automatic and semi- automatic image classification, though most of them fail because of unknown noise, poor image contrast, inhomogeneity and boundaries that are usual in medical images. The MRI (Magnetic resonance Imaging) brain tumor segmentation is a complicated task due to the variance and intricacy of tumors. The principle aim of the project is to perform the MRI Brain image classification of cancer, based on Rough Set Theory and Feed Forward Neural Network classifier. For this purpose, first the features are extracted from the input MRI images using Rough set theory, and then the selected features are given as input to Feed Forward Neural Network classifier. Finally, Feed Forward Neural Network classifier is utilized to perform two functions. The first is to differentiate between normal and abnormal. The second function is to classify the type of abnormality in benign or malignant tumor.

In the present paper we have studied the size dependence effective band gap of semiconductor Silicon ( Si ) nano-solid. The band gap is one of the most significant electronic parameters of semiconductor material. The band gap of semiconductor dependents on the temperature, pressure, composition, number of atoms as well as size of the solid. When semiconductor solids are prepared in the form of nano-metric level, their small particle size gives rise to quantum confinement and the energy bands are split into discrete levels. It is found that the effective band gap decreases with increasing the size (diameter and number of atoms) of Si nano-solid. Another conclusion is that the energy band gap of semiconductor tend to decrease with increasing temperature and hence atomic vibration increases.

The development of practical sensors for the detection and quantification of heavy metals ions in the samples is the subject of considerable research. A glutathione stabilized silver nanoparticles (GSH-AgNPs) modified screen printed electrode was proposed to determine the trace levels of Pb(II) by using cyclic voltammetry. Maximum current was obtained at the potential range of 0.263 V. The electrostatic redox peak current shows a linear response towards the concentration of Pb(II) and linear calibration curves were obtained. The limit of detection was determined as 4.963×10-8 M and the sensitivity response is 10-5 mV with a scanning rate of 100 mV/s.

Defected ground structure have been always an area of interest for research in millimetre waves and microwaves. In this paper, the different parameters of a defected ground structure which helps in lowering cut-off frequency and resonant frequency of microstripline have been analysed. A circularly shaped defected ground structure which is equivalent to LC model circuit has been simulated and its performance characteristics are studied. As the complexity of a structure increases, due to slow wave effect there is variation in the cut-off frequency and resonant frequency. These variations are useful in size, mutual coupling reduction and harmonic suppression which help in designing of various microwave circuit.

Fiber reinforced polymer (FRP) composites plays an important role in many industries; because weight to strength ratio is extremely high when compared to monolithic metals. One of the main limitations of FRP composites are the low mechanical properties due to the presence of polymer associated with it. To solve this problem, material engineers are investigating the use of different nanoparticles mixed in different polymers to improve mechanical properties of the polymer. In the present investigation nano Copper Oxide (CuO) materials dispersed in polystyrene resin using ultrasonic bath sonicator are used as matrix face for glass fiber reinforced plastics which is manufactured by hand layup processes. As per ASTM standards tensile and compression test are carried out in universal testing machine. Microstructure of samples has been investigated by scanning electron microscope (SEM). Hence the dispersion of reinforcement was noted. A Linear regression model has been developed to predict mechanical properties of nano filled GFRP composites The results indicated that the predicted values through the developed model are well agreement with the experimental results and with increase in weight % of nano CuO improves the the mechanical properties.

Silver nanoparticles have successfully synthesized by using tri-sodium citrate as reducing agent and Polyvinyl alcohol (PVA) as capping agent and demonstrated the effect of reducing agent concentration on size variation. Broadened XRD peaks confirmed the formation of nanosized silver nanoparticles with face centred cubic structure and is consistent with FESEM studies. Further XRD results confirmed the decrease of mean particle size with increase of reducing agent concentration. FESEM images illustrate the formation of spherical silver nanoparticles in nanometre regime. EDAX analysis confirms the presence of elemental silver indicating that silver peak is correctly identified ensuring the absence of impurities in the prepared nanoparticles. UV-Visible absorption studies revealed the blue shift of surface Plasmon resonance (SPR) band owing to decrease of particle size with increase of reducing agent concentration.
