Magnetoelectric effect has attracted considerable interest due to the promising approach towards novel spintronics device. In this work, we study the converse magnetoelectric properties of PZT/NiFe/CoFe nanocomposites in which the piezoelectric substrate is transversely polarised and the thickness of the NiFe layer is…
tion of hydrophilic polymers. Out of these three methods, dispersion of preformed polymers is a common technique used to prepare biodegradable nanoparticles. In this method, the polymer is dissolved in an organic solvent which is also used for dissolving the hydrophobic technical grade material which may be a drug or…
Fatigue crack closure in commercially pure titanium sheets severely deformed using the accumulative roll-bonding (ARB) process were investigated. Sheet processed through 6 cycles of ARB consists of fine equiaxed grains and elongated lamellar grains and shows a high 0.2% proof stress of 790 MPa. Fatigue crack closure w…
A series of blend fibers based on a certain weight polypropylene (PP) and poly(butyl methacrylate- co-hydroxyethyl methacrylate) (PBMA- co-HEMA) were prepared via melt spinning in a corotating twin screw extruder. The morphology and structure of the blend fiber was studied by stereoscopic microscopy, polarized optical…
In order to improve the efficiency of grain refinement, a study on the modified process (called Non-equal channel angular pressing) from the conventional equal channel angular pressing has been conducted. The deformation behavior of aluminum alloy AA1050 deformed by the Non-equal channel angular pressing which has a s…
Nickel ferrite nanoparticles were prepared by a modified sol-gel technique employing coconut oil, and then annealed at different temperatures in 400-1200 °C range. This route of preparation has revealed to be one efficient and cheap technique to obtain high quality nickel ferrite nanosized powder. Sample particles siz…
This study investigated the treatment of a liquid radioactive waste containing uranium (235U + 238U) using nanofiltration membranes. The membranes were immersed in the waste for 24-5000 h, and their transport properties were evaluated before and after the immersion. Surface of the membranes changed after immersion in…
Using a laboratory-scale plasma device, plasma-driven and gas-driven permeation of hydrogen through a ferritic steel alloy: F82H has been investigated under some of the DEMO-relevant conditions. The steady state plasma-driven permeation flux has been found to be strongly affected by the variation in upstream surface m…
The polycrystalline samples of GdFe 1-x Ni x O 3 (x=0.0, 0.1) are prepared by solid state reaction route, their structure is analyzed by powder X-ray diffraction (XRD) and Rietveld refinement. We are also studying the behavior of dielectric constant (ε′), tangent loss (tan δ) as a function of frequency from 75 kHz to…
The availability of a wide array of colloidal organic/inorganic nanostructures has opened up an interface to establish highly innovative and attractive hybrid materials for a number of optoelectronic applications recently. In this regard, a colloidal route has been established to fabricate hybrid photodiodes and study…
The longitudinal (15)N relaxation rate and (15)N{(1)H} NOE enhancement were determined for porphycene in a CD2Cl2 solution. By invoking the rotational diffusion tensor of porphycene as previously determined, these data could be used to evaluate the tautomerization rate of protons in the NHN bridges. The proton transfe…
In the present paper, we have studied the effect of Ge addition on the physical properties of Se-Sn-Pb chalcogenide ma- terial. The necessary physical parameters which have important role in determining the structure and strength of the material viz. constraints, coordination number etc. have been calculated. The incr…
Experimental IR and Raman spectra of solid acetazolamide have been analysed by computing the molecular structures and vibrational spectra of monomer and dimer forms and water clusters of acetazolamide. The possible stable conformers of free acetazolamide molecule in the ground state were obtained by scanning the poten…
Conducting poly (3-hexylthiophene) (P3HT) was synthesized electrochemically in aqueous medium and characterized by electrochemical impedance spectroscopy, Tafel, SEM and TEM. The antidepressants drugs diazepam (DIZ), nitrazepam (NITZ) and imipramine (IMI) were analyzed on nanosize P3HT modified glassy carbon electrode…

In this research, the partial discharge resistance was examined for eight kinds of polymer samples, namely, low-density polyethylene, polypropylene, poly-methyl-pentene, atactic polystyrene, syndiotactic polystyrene, polyethylene terephthalate, polyethylene naphthalate, and polyimide. An ac 500-Hz voltage with a desig…
Our ultrafast optical pump-probe measurements of 2D atomic material MoS2 show that the interband and intraband relaxation dynamics of photoexcited carriers vary significantly as a function of the number of atomic layers. Coherent phonon oscillations are also observed in our measurements.
For the first time, capability of the cesium salt of sodium 30-tungstopentaphosphate, the so-called Preyssler’s anion (CsP 5 ), as a green and eco-friendly polyoxometalate was investigated in the synthesis of gold nanoparticles and decoration of titanium dioxide with gold nanoparticles. Gold nanoparticles and nanocomp…
In this study, the doped poly(3,4-ethylene dioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) film was introduced as an anode buffer layer into the poly(3-hexylthiophene) (P3HT):[6,6]-phenyl-C61-butyric acid methyl ester (PCBM) system for organic photovoltaic devices (OPVs). The doped PEDOT:PSS films were prepared by…
We consider the stability of a specific nematic liquid crystal configuration under an applied magnetic field. We impose the strong anchoring condition, and we allow the boundary data to be nonconstant and also the applied field to be nonconstant. Thus, we shall extend the results of Lin and Pan in 2007. We show that f…
