Electrodeposition of Zinc-Iron alloy has been used to improve the corrosion resistance of mild steel. This alloy plating was successfully coated on mild steel using the electrodeposition technique. Under varied deposition conditions, the zinc-iron alloy films onto the steel plate were examined. The purpose of this study is to describe the corrosion characteristics of the coated sample in 3.5% NaCl for the application of novel, sacrificial coatings for the defence of steel structures. It has been thoroughly examined how plating variables including bath composition, pH, and current density affect the composition, morphology; and corrosion properties of the coatings were discussed. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) are used to analyze the morphological characteristics and phase structure of the coatings. The surface roughness of the coating was measured by Atomic Force Microscopy (AFM). The Vickers indenter was employed to measure the microhardness of the coated sample. The corrosion resistance of Zn-Fe alloy coatings was assessed using electrochemical impedance spectroscopy (EIS) and polarization techniques at different current densities. The new low-cost Zn-Fe alloy coating was used for automobile applications. [ABSTRACT FROM AUTHOR]

In this paper, we describe the synthesis of integrated pyrazole derivatives carrying quinolone moiety by conventional technique. Pyrazole derivatives were synthesized by condensation of hydrazide and ethyl-3-oxo-2-(2-phenylhydrazilidiene) butanoate. Fourier transforms infrared (FT-IR), 1H-Nuclear magnetic resonance, 13C-Nuclear magnetic resonance (NMR), and liquid chromatography-mass spectrometry (LCMS) studies were used to confirm the structure of the compounds. Docking studies were carried out against the antimicrobial target to know the interaction of the molecules (ligands) with the docked target. Among the docked compounds pyrazole derivative brominated compounds 4d, 4e, 4f, 4g, and 4h violated Lipinski's Rule of Five and thus were not suitable leads. Comparing the synthetic compounds 4c, 4g, and 4i to the reference drug ofloxacin, they exhibit excellent antibacterial activities. [ABSTRACT FROM AUTHOR]

We report on the electrodeposition of a zinc-nickel alloy using a sulphate bath on mild steel (MS) substrate. The Hull cell experiment was used to optimize the bath composition and operating conditions. Sulphanilic acid (SA) was used as an additive for the coatings. The bath demonstrated an abnormal co-deposition with more zinc being deposited over nobler nickel. The effect of temperature and current density on the coating thickness, hardness, corrosion resistance, and weight % of Ni content in the coating was investigated. The corrosion behaviour of coated zinc-nickel alloy film in sodium chloride (wt.% 3.5) solution was investigated using potentiodynamic polarization and electrochemical impedance spectroscopic approaches. The nickel content in the coatings was determined through the colorimetric method and verified by the energy dispersive X-ray spectroscopy (EDX) technique. Atomic force microscopy (AFM) and Scanning electron microscopy (SEM) techniques were used to determine the surface roughness and surface topography, of the coatings. The results show that the zinc-nickel coatings had the highest corrosion resistance (0.213 mm y-1) at optimal current density (3A dm-2). Thus, due to their superior corrosion resistance Zn-Ni coatings have been largely used to protect the mild steel components in many industries including the automotive, military, and aerospace segments.

The physicochemical quality of drinking waters of 6 sources from Talakaveri river and different parts of NMAMIT campus(Nitte-Udupi distic) was studied. Drinking water sample was first taken from the filtrate after the water was led into the filter. Second water sample was taken from tap. Ground water sample was taken from well and other three samples were taken from lake, falls and river. The physicochemical quality of drinking water was affected by the origin of raw water. The quality goal was exceeded by all drinking water samples. In general, the physicochemical quality of drinking waters from different sources were rather similar. This project is based on analysis of physical, chemical quality of different water samples. The water samples were collected from different sources. The purpose of our study is to bring an awareness regarding portability of water among people. We can also develop new techniques to eradicate water borne diseases and new equipment's to prevent water pollution from our studies. The water samples were collected during rainy season in the month of June and July of the year 2018. The parameters used to analyse the quality of water is also called as water quality index. The major properties analysed are as follows: Taste and Odour, Colour, Temperature, Total dissolved solids, Total suspended solids, Determination of pH, Conductivity and Turbidity.
