In this study, tamoxifen-loaded chitosan-pluronic nanoparticles have been prepared by an ionic gelation (IG) method. Particle size analysis, Scanning electron microscopy (SEM), Zeta potential measurements, Fourier transform infrared spectroscopy (FT-IR) and differential scanning calorimetry (DSC) were used for nanoparticle characterization. The cytotoxicity of the nanoparticles was assayed in the MCF-7 cell line. The optimized tamoxifen loaded nanoparticles had a spherical shape with positive charge and mean diameter 150 to 300 nm. The FT-IR and DSC studies found that the drug was dispersed in amorphous form due to its potent interaction with nanoparticles matrix. The maximum encapsulation efficiency was obtained at 8mg/ml tamoxifen. The tamoxifen loaded chitosan-pluronic nanoparticles had good blood compatibility and the particles were nontoxic to the MCF-7 cell line. All study results suggest that the nanoparticles could be used as an effective drug delivery carrier for the breast cancer treatment.

Here is an effort to present the rapid, reliable and eco-friendly synthesis of gold nanoparticles (GNPs) by green biogenic approach. The method uses aqueous extracts of Betel leaf, Hibiscus leaf, Lantana camara and nuts of bitter guard as reducing as well as stabilizing agent. Gold nanoparticles were synthesized by thermal reduction (microwave irradiation) of chloroauric acid (HAuCl4) using aqueous extracts of plant materials mentioned above. The formation of gold nanoparticles was confirmed by using UV-Visible spectra. Gaussian curves with absorbance peaks were obtained between 500 nm to 600 nm which confirms to similar previous investigations. Bioreduction of 0.5 mM and 1mM HAuCl4 by varying gold salt and extract ratio were investigated. Approximate sizes of synthesized GNPs were predicted using Mie Plot software according to which they vary in the range of 26-63nm.

Ruthenium oxide (RuO2) nanoparticles were supported on the outer surface of single walled carbon nanotubes (SWNTs) using chemical reduction technique. The nanocomposite was employed as an electrode material for charge storage capacitor using ionic liquid, 1-ethyl-3-methylimidazolium tetrafluoroborate electrolyte solution. The electrochemical charge storage properties of the composite were investigated using two electrode cyclic voltammetry and galvanostatic charge-discharge techniques. The specific capacitance and energy density of the RuO2-SWNT nanocomposite electrode material based on the fabricated coin cell supercapacitor were measured to be as high as 174 F/g and 74 Wh/kg at current density of 1 A/g.

The main objective of the paper is to study the thermo-physical properties of acetone/water mixture as a function of a different volume fraction at the different operating temperatures. This paper deals with the study on the acetone/water mixture, mainly the enhancement of heat transfer co-efficient, thermo-physical properties such as thermal conductivity, specific heat and viscosity. The thermo-physical properties play a major role for the heat transfer enhancement. The experimental set up will lead to more heat transfer applications in future.

In this report, we present the spectroscopic features of nanostructured undoped and RE (rare earth) doped TiO2 system. Undoped an RE doped TiO2 nanostructures were fabricated using conventional sol-gel method. The structural properties of synthesized nanostructures were characterized by X-ray diffractrogram (XRD) and high resolution transmission electron microscopy (HRTEM). XRD spectra shows the anatase phase of TiO2 in all the spectra and HRTEM image shows ~ 7nm particle size for the all the samples. The spectroscopic properties were studied by UV-Visible spectroscopy, Fourier transformed infrared spectroscopy and photoluminescence spectroscopy. The emissions due to color centers and oxygen vacancies of TiO2 were also evident in the PL spectra. The luminescent property of Tb and Eu-doped TiO2 samples has been studied and it showed selected D-F transition. A weak emission peak at ~490 and ~544 nm corresponding to 5D4→7F6,5 transition of Tb3+. Whereas Eu doped TiO2 nanoparticles exhibited different intra 4f Eu3+ ion related transitions with the most intense red emission (5D0→7F2) peak observable at ~613 nm.

Thin film of CuO and CdO were prepared for making heterojunction. The films were prepared by radio frequency magnetron sputtering technique. The junction shows outstanding electrical properties and particularly the electrical properties of CuO were found to be highly effected and enhanced. Carrier diffusion and carrier tunnelling through the interface potential lead to the outstanding electrical properties of the heterojunction. These types of heterostructures are potential candidate for different device applications such as field emission display and optoelectronic devices.

Wireless sensor network (WSN) is a group of interconnected sensor nodes, usually broaden out in areas which are not easily accessible and communicate wirelessly. A sensor node is capable to sense environment, communicate the gather information to another nodes and also have computing power. The use of ubiquitous wireless sensor networks has increased the complexity day by day to identify wireless sensor network attacks and there countermeasures. In this paper, different types of vulnerabilities associated with WSN and their effects, countermeasures are discussed.

Cr doped CdO thin films were deposited on glass substrates by DC reactive magnetron sputtering method with individual Cd and Cr metallic targets. The effect of Cr concentration (1% to 5%) on structural, electrical and optical properties of CdO films was investigated. The structural studies reveal that the films are polycrystalline with preferred orientation along (2 0 0) plane. The shift of the diffraction peak (2 0 0) towards higher angles with the increase of Cr concentration indicates the presence of stress in the films. SEM images consist of agglomerates and no distinguished grains are seen. Energy Dispersive Analysis of X-rays (EDAX) is carried out for the compositional analysis of prepared thin films. The optical transmittance of 85 % and minimum resistivity of 1.73 × 10-4 Ω.cm is obtained for 3% Cr doped CdO thin films. A blue shift of the band edge has been observed for the Cr doped CdO films with the increase of Cr Concentration. This blue shift is due to Burstein -Moss effect, which arises due to increase in free carrier concentration. The optical band gap of Cr doped CdO thin films increases from 2.35 to 2.85 eV with the increase of Cr concentration. The optical constants such as absorption coefficient (a), extinction coefficient (k) and refractive index (n) were determined from the optical transmission data.

This report describes fabrication of ZnO nanowire based nanogenerator used to simultaneously harvest both light and ambient mechanical vibration. The ZnO nanowires used in this work were grown on p-type Si substrates employing seed mediated low-temperature aqueous solution method. Using the synthesized ZnO nanowire and conducting ITO plate a sandwich type ITO/n-ZnO NW/p-Si cell was fabricated and its ability in simultaneous harvesting of light and mechanical energy has been studied. This design of piezoelectric and photoelectric hybrid nanogenerator is first of this kind of devices ever fabricated to harvest more than one type of ambient energy.
