North Maharashtra University was established on August 15, 1990 after separating it from the parent University of Pune.The university campus is located at Jalgaon in Maharashtra, India. It occupies an area of 404 acres on the banks of Girna river. Massive plantation has been undertaken to enrich the natural beauty of the campus. In 2001, NAAC Accredited the prestigious 4 Star Status to the University. The university was reaccredited by NAAC as 'B' grade university.Separate hostel facilities for male and female students are available on the campus on the basis of merit and certain other restrictions. Staff quarters are located within the campus.The university library has six floors and more than 50,000 books. There are more than 500 magazines subscribed in the Library reading section.Research students of the North Maharashtra University establish the North Maharashtra University Research Scholar Association on the 14 September 2009 by the hand of Honorable Prin. Dr. K. B. Patil .Currently there are 62 members comprising the university's teaching faculty. Wikipedia.

The persistence of endosulfan and intermediate metabolite endosulfan sulfate in the environment and their toxic effects on biota necessitate their removal. This study investigated the bioaugmentation of endosulfan-contaminated soil by fungal inoculant Aspergillus niger ARIFCC 1053. The influence of bioaugmentation by A. niger on endosulfan-contaminated soil was evaluated with the help of change in pH and released chloride, and by thin layer chromatography and gas chromatography analysis. Its effects on soil functionality were monitored by estimating dehydrogenase and arylsulfatase enzyme activities. The endosulfan degradation reached an undetectable level on day 15. The pH of the medium was nearly neutral (6.9) at the time of inoculation and it decreased to 3.6 on day 15. The amount of chloride released at particular intervals in the endosulfan degradation ranged from 28 mg mL-1 to 104 mg mL-1. Change in pH and the increase in released chloride correlated with metabolic activities involved in the simultaneous degradation of endosulfan. Endosulfan sulfate, an intermediate metabolite, was detected and had disappeared on day 11 of the process. The increase in enzyme activities is an indicator of soil fertility and suggests possible involvement of these enzymes in endosulfan degradation. These results demonstrate that bioaugmentation by A. niger may be a viable tool for the remediation of soil contaminated with endosulfan. © TÜBITAK. Source

The α-Fe2O3 nanorods were successfully synthesized without any templates by calcining the α-FeOOH precursor in air at 300 °C for 2 h and their LPG sensing characteristics were investigated. The α-FeOOH precursor was prepared through a simple and low cost wet chemical route at low temperature (40 °C) using FeSO 4·7H2O and CH3COONa as starting materials. The formation of α-FeOOH precursor and its topotactic transformation to α-Fe2O3 upon calcination was confirmed by X-ray diffraction measurement (XRD), X-ray photoelectron spectroscopy (XPS), field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM) analysis. The α-Fe 2O3 nanorods exhibited outstanding gas sensing characteristics such as, higher gas response (∼1746-50 ppm LPG at 300 °C), extremely rapid response (∼3-4 s), relatively slow recovery (∼8-9 min), excellent repeatability, good selectivity and lower operating temperature (∼300 °C). Furthermore, the α-Fe2O 3 nanorods are able to detect up to 5 ppm for LPG with reasonable response (∼15) at the operating temperature of 300 °C and they can be reliably used to monitor the concentration of LPG over the range (5-60 ppm). The experimental results clearly demonstrate the potential of using the α-Fe2O3 nanorods as sensing material in the fabrication of LPG sensors. Plausible LP G sensing mechanism of the α-Fe2O3 nanorods is also discussed. © 2010 Elsevier B.V. All rights reserved. Source

Electrochemical polymerization of the aniline, o-anisidine and o-toluidine coatings on low carbon steel has been carried out under galvanostatic conditions in an aqueous oxalic acid solution. The E-t curves show three distinct stages - dissolution of the low carbon steel surface and formation of polycrystalline iron oxalate interphase, complete passivation of low carbon steel surface and the electrochemical polymerization of respective monomer(s). To understand the role of monomer(s) during the electrochemical polymerization process, the passive interphase samples were characterized by X-ray photoelectron spectroscopy. The results of this study show that monomer(s) are taking a part in first stage of electrochemical polymerization and passivation time depends on the type of monomer(s) present in electrolyte. © 2012 Elsevier Ltd.

Poly(o-toluidine) (POT) coatings were electrochemically synthesized on 304 stainless steel using cyclic voltammetric method. These coatings were characterized by Fourier transform infrared spectroscopy, UV-vis absorption spectroscopy, and cyclic voltammetry. The corrosion performance of POT coating in aqueous 3 wt% sodium chloride was assessed by the electrochemical techniques such as open circuit potential measurements, potentiodynamic polarization technique, cyclic potentiodynamic polarization measurements, and electrochemical impedance spectroscopy. The results reveal that POT coating on 304 stainless steel prevents general and localized corrosion, and reduces the exchange current density almost by a factor of 45 than bare 304 stainless steel. © 2012 Springer-Verlag.

Polyaniline (PANI) coatings were electrochemically synthesized on nickel (Ni) coated mild steel (MS) and their corrosion protection properties were investigated. In this work, the Ni layer (∼1 μm thick) was electrodeposited on MS under galvanostatic condition. Thereafter, the PANI coating was deposited over the Ni layer from aqueous salicylate medium by using cyclic voltammetry. These bi-layered composite coatings were characterized by cyclic voltammetry, UV-vis absorption spectroscopy and Fourier transform infrared (FTIR) spectroscopy. The corrosion protection properties of Ni coated MS (Ni/MS) and PANI coated Ni/MS (PANI/Ni/MS) were investigated in aqueous 3% NaCl by using open circuit potential (OCP) measurements, potentiodynamic polarization technique and electrochemical impedance spectroscopy (EIS). It was shown that the top layer of PANI exhibits a lower porosity behavior with respect to Ni coating and reduces the corrosion rate of Ni/MS almost by a factor of 3500 and increases the lifetime of Ni coating. © 2011 Elsevier Ltd.
