The Pb1-xNixTiO3 (x = 0.0, 0.2, 0.4, 0.5, 0.6, 0.8 and 1.0) nanoparticles are synthesized by sol-gel method and microwave sintering technique. Samples calcinated at 730 °C exhibit pseudo-cubic crystal structure, further sintering at 1000 °C the samples exhibited tetragonal structure except x = 0.8. The crystallite size is found to be 47–39 nm. Fourier Transfer-Infra Red studies confirm the Pb–Ti–O, Ti–O and Ni–O bond formation of prepared samples. The optical excitation spectrum reveals that the samples have direct allowed energy bandgap values of 2.81 to 2.82 eV. Synthesized samples particle size found to be 1 μm to 31 nm from High-Resolution Scanning Electron Microscope analysis. The particle size is found to be decreasing on increasing the nickel concentration. X-ray powder diffraction and electron microscope profiles confirmed single phase behaviour of the compounds in lower concentration of nickel. The prepared compounds show nearly spherical shape morphology with an average particle size of 1 μm to 31 nm which is close to crystallite size determined from the XRPD. The temperature dependent dielectric constant (ε) measurement show low values at room temperature and were nominally changes with increasing temperature upto 350 K. The ac electrical study of synthesized samples confirms the negative temperature coefficient of resistance and thermally activated charge carriers are responsible for the high-temperature behaviour. At room temperature prepared samples exhibited superparamagnetic nature. The saturation magnetization (Ms) and coercivity values are found to be 0.08–15.9 emu/g and 236–195 Oe at 15 kG field strength. © 2018 Elsevier B.V.

Electrical and magnetic properties of lead nickel titanate synthesized by sol-gel method and microwave processing

Vehicular Ad-hoc Networks (VANET’s) is the recent technology to facilitate the study of simulators. The mobility model and physical layer are the issues in the simulator which impact the output greatly. The simulations of the routing algorithm in the VANET’s are still the major problem. The comparison between the routing protocols is addressed by only some few works. In order to overcome these issues and problems we made a comparison between the hybrids, reactive, geographic routing and pro-active routing protocols by using a simulation platform by integrating the mobility and the physical layer models. It also performs a comparison between the multi-path routing protocols with Ad-hoc network which allows adapting the faster performance. By using the BDYMO protocol in the VANET communication, the overhead in the network is minimized and the performance is improved.

Abstract: Of all the piezoelectric ceramics, lead titanate (PbTiO3) has an important place as an electromechanical transducer. In the present article PbTiO3 synthesized by sol–gel technique and microwave processed is presented. The sintered PbTiO3 is found to be of high density. The sintered PbTiO3 crystal structure and crystallinity confirmed by powder X-ray diffraction and sample weight loss and decomposition investigated by thermal analysis. Prepared PbTiO3 functional groups confirmed by FT-IR spectrum and phase formation analyzed by Raman spectra. Sample spherical morphology confirmed by high-resolution scanning electron microscopy (HRSEM) and transmission electron microscopy (TEM). The particle size found to be 77 nm from TEM. The variation of dielectric constant and ac conductivity with temperature and frequency of PbTiO3 are investigated. The value of σdc is found to be 1.767 × 10−2 S/cm at transition temperature using the Nyquist plot. The ferroelectric hysteresis loop and piezoelectric coefficient d33 confirm the ferroelectric and piezoelectric nature of the PbTiO3 (PT).

Application of nano particle in the treatment of municipal solid waste leachate is of recent interest. In this paper, the effectiveness of silica nano particles synthesized from blast furnace slag and iron nano particle synthesized from chemicals was studied for the removal of organic pollutants and color. The synthesized nano particles were characterized using SEM, TEM, EDX and FTIR analysis. Batch experiments were conducted to remove the BOD, COD and color from Aged landfill leachate (ALL) and leachate from the composting yard (CYL).Influencing parameters like pH, contact time, nano particle dosage and Hydrogen peroxide concentration were studied. The maximum removal was achieved at the pH of 6 for both the nano particle, contact time 90 minutes for silica nano particle and 120 minutes for iron nano particle, silica nano particle dose as 0.4g/50 ml, iron nano particle dose as 0.3g/50ml and hydrogen peroxide concentration was found to be 3M and 4M for silica and iron nano particles respectively. The removal efficiency in CYL and ALL using silica nano particle was obtained as 87.15%, 72.72%, 83.15% and 82.5%, 62.5%, 77.34% for color, BOD and COD respectively. Similarly for iron nano particle, the removal efficiency was found to be 60.3%, 65%, 67.43% and 57.06%, 57.27%, 67% for the removal of color, BOD and COD in CYL and ALL, respectively.

Removal of COD, BOD and Color from Municipal Solid Waste Leachate using Silica and Iron nano particles - A Comparative Study

Escherichia coli have public health impact on humans by causing gastroenteritis including hemorrhagic colitis and hemolytic uremic syndrome. A total of 215 samples collected from fast foods, swabs from meat shops and fish markets were examined. Thirty-six samples (16.74%) were identified as E.coli with various serogroups like O8, O19, O22, O41, O60, O101, O116 and O147, respectively. Only nine (25%) E.coli possessed the gene encoding shiga toxin (stx 1). Isolated E.coli were multidrug-resistant with complete resistance to fluroquinolones (ciprofloxacin, norfloxacin, ofloxacin, and lomefloxacin respectively). Isolation of stx 1 bearing E.coli with multidrug resistance from fast food and meat sources is a clear indication of environmental contamination and is a matter of public health concern. Practical Application: Detection of diarrheogenic serogroups of stx 1 harboring Escherichia coli with multidrug resistance in fast foods and meat shops is applicable in creating awareness among public about the unhygienic practices followed in the fast food centers and retail meat shops and also the improper disposal of fecal and antibiotic wastes, which is the cause for such contaminations. This study also insists the need of health education and hygienic practice for the food handlers. © 2013 Wiley Periodicals, Inc.
