domain of 0.2-0.85 V/SCE, at a scan rate of 20mVs -1 , using either 0.1M pyrrol (Py) in 0.2M H 2 SO 4 or 0.3M Py in 0.2M oxalic acid as aqueous electrolytes. The morphology of composite films was observed by scanning electron microscopy (SEM). The electrochemical capacitance properties of the composite films were meas…
Natural sepiolite from Andrici (Serbia) was functionalized by covalent grafting of N-[3-(trimethoxysilyl)propyl]ethylenediamine triacetic acid trisodium salt to the Si-OH sepiolite groups. The functionalized material, MSEAS, was characterized by determination of phase composition by X-ray diffraction (XRD) analysis, a…
In search of efficient materials for photo anode for DSSC, we made an attempt to prepare pure and transition metal (Zn 2+ , Cd 2+ and Ni 2+ ) doped Tio2 simple microwave irradiated solvothermal method. The samples were characterized by structural and optical measurements. The particle size increased as the addition of…
With the purpose of obtaining compositionally uniform ingots during Ohno continuous casting of a dilute industrial aluminum alloy through eliminating segregation due to convection, a magnetic field strength required to damp natural convection and suppress macrosegregation was numerically determined. This was achieved…
The present work focuses on the effect of magnesium (Mg 2+ ) substitution on structural, microstructural and infrared studies of the nanocrystalline cobalt ferrite (CoFe2O4). The samples of Co 1-xMg xFe2O4 nanocrystalline spinel ferrite of different compositions with x = 0.0 and 0.25 have been synthesized by solgel au…
The antimicrobial effect of the polyamide 6/66-chitosan blend obtained by extrusion and chitosan-coated plastic films was compared with pure chitosan films and chitosan solution against Escherichia coli, Listeria monocytogenes and Bacillus cereus. The films from polyamide 6/66-chitosan blend had no antibacterial activ…
2 ABSTRACT: Bulk crystal of bis thiourea cadmium chloride (BTCC) was grown by the solvent evaporation method and slow cooling method. The crystal structure was confirmed using single crystal XRD studies. The presence of thiourea in the complex and the metal-sulphur bond has been confirmed from the FTIR and Raman spect…
Layer by Layer (LbL) thin films stemming from the formation of stereocomplex between oligolactate with opposite chirality (OLLA and ODLA) covalently anchored onto poly(vinyl alcohol) (PVA) chains is described herein for the first time.
Steel, as an indispensable material in modern engineering and structural applications, continues to be highly relevant in the field of nanocrystalline materials. Devising innovative methods in addition to understanding the deformation physics of those materials are of great importance in modern research fields to enha…
Fouling-resistant cellulose acetate (CA) membranes were prepared by the phase inversion technique using hydrophilic aminated polyethersulfone (APES) as the modification agent. In the presence of polyethylene glycol 600 as a pore forming agent, were blended in 100/0,90/10,80/20,70/30% compositions using N,N- dimethylfo…
From an era the over-exploitation of petrochemical based nonbiodegradable packaging materials have led to threat our environment in a serious way, which necessitates the need for the use of natural polymer based packaging materials in food packaging & wrapping which not only maintains the quality and safety but also e…

Metal complexes of some transition metal ions viz Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and Hg(II) have been synthesized from a Schiff base (L) formed by the condensation of 3-amino-5-bromobenzofuran-2carboxamide and 2-hydroxy-1-napthaldehyde. Synthesized compounds have been studied by various spectroscopic technique…
This work are studying the effects of shot peening time on corrosion behaviors of AA 6061-T6 in aqueous solutions. Many specimens prepared for Corrosion test with the dimensions of (15*15*3) mm according to ASTM G71-31. The shot peening process using steel ball have diameter 2.75 mm and shot peening time at (15, 30, 4…
The aim of this work is to conduct an optimized conditions of the post weld heat treatment of the GTAW(gas tungsten arc welding) and SMAW (shielded metal arc welding) weld joint between P11 (1.1 Cr) and P91 (8.5 Cr) steels; using E9018B3/ER90SB and E9015B9/ER90SB9 as filler metals. The post weld heat treatment was con…
measurement takes place with the digitizers and the DUT measuring the power simultaneously.
Analysis of the formation and evolution of carbide phase in medium carbon steel with a bainitic structure during compressive deformation was performed by means of transmission electron diffraction microscopy. Qualitative transformations in carbide phase medium size particles, their density and volume concentration dep…
Research on anti-stab utilizing various types of fiber reinforcement and matrix materials in the production of laminated composite have been increased very rapidly over the past decade to investigate the performances and behavior of anti-stab. This review summarized recent research on production of laminated composite…
