The objective of the present study is the formation of single phase\nZn1−xTMxO thin films by PLD and increase the solubility limit of TM\ndopants. The TM doped ZnO nanostructures were also grown by hydrothermal\nmethod. The structural and morphological variation of ZnO:TM thin\nfilms and nanostructures with TM doping…
Use of short fibers as reinforcing fillers in rubber composites is on an\nincreasing trend. They are popular due to the possibility of obtaining anisotropic\nproperties, ease of processing and economy. In the preparation of these composites\nshort fibers are incorporated on two roll mixing mills or in internal mixers.…
Les Piles à Combustible Microbiennes (PCMs) mettent en œuvre le métabolisme de micro-organismes et utilisent de la matière organique pour générer de l énergie électrique. Les applications potentielles incluent le traitement de l eau autonome en énergie, les bio-batteries, et le grappillage d énergie ambiante. Les PCMs…
We have investigated magnetization(M), magnetocaloric effect(MCE) and magnetothermopower(MTEP) in polycrystalline Pr0.6Sr0.4MnO3, which shows a second-order paramagnetic to ferromagnetic transition near room temperature (TC = 305 K). However, field-cooled M(T) within the long range ferromagnetic state shows an abrupt…
We obtain the maximum sum-connectivity indices of graphs in the set of trees and in the set of unicyclic graphs respectively with given number of vertices and maximum degree, and determine the corresponding extremal graphs. Additionally, we deduce the n-vertex unicyclic graphs with the first two maximum sum-connectivi…
This is the second in a series of papers in which we derive a\n$\\Gamma$-expansion for the two-dimensional non-local Ginzburg-Landau energy\nwith Coulomb repulsion known as the Ohta-Kawasaki model in connection with\ndiblock copolymer systems. In this model, two phases appear, which interact via\na nonlocal Coulomb ty…
Graphene nanopore based sensor devices are exhibiting the great potential for the detection of DNA. To understand the fundamental aspects of DNA translocating through a graphene nanopore, in this work, molecular dynamics (MD) simulations and potential of mean force (PMF) calculations were carried out to investigate th…
Introduction Historically, each of the three traditional macromolecular architectural classes (i.e. I. Linear, II. Cross-linked, III. Branched) have opened very rich polymer science frontiers. The importance of each major architectural class is apparent from the recognition they have received based on named Nobel laur…

Abstract Compounds (III) and (VI) crystallize in the orthorhombic space group Pn21a (powder XRD and neutron diffraction) and contain three‐dimensional Na/Li paths supported by P2O7 pillars in the crystal.
Diagnostics Immunoassays The dense presentation of terminal functional groups found on the surface of dendrimers makes these nano-structures ideal for enhancement of signal amplification in diagnostic applications. For example, in solid-phase bioassays, dendrimers may be used as structural components to increase the d…
An optical fiber doped with bismuth was fabricated using the modified chemical vapor deposition method. Both the linear and nonlinear optical properties of the glass fiber were investigated. The resonant nonlinear refractive index was found to be around 3 10 15 m 2 W 1 , which is five orders of magnitude larger than t…
MR effects in epitaxial Fe:MgO anti-granular systems, which consist of MgO nanoparticles in an Fe matrix, have been studied at room temperature. Fe and MgO were co-evaporated on MgO(001) substrate in the ratio of Fe:MgO = 4:1, 3:1, and 2:1. The samples were annealed for up to 5 h inducing a uniaxial anisotropy. The sa…
We present the results of the magnetic domain structures of BaAl2Fe10O19nanopowders prepared by a self-propagating combustion process. Amorphous precursors were calcined at 850 °C for 2 h with NaCl (Sample I) and without NaCl (Sample II). The transmission electron microscope and atomic force microscopy images evidentl…
Co epitaxial thin films are prepared on (111)-oriented fcc-Au and fcc-Ag underlayers with island-like surfaces consisting of wide top (111) terraces surrounded by narrow side {111} and {100} facets by using an ultrahigh vacuum molecular beam epitaxy system. The influences of side facet of underlayer on crystallographi…
The critical issue facing head-disk interface (HDI) design is determining the optimal combination of lubricant and overcoat materials. A high performing lubricant should have sufficient adhesion to the carbon overcoat (COC) layer to prevent spin-off, while the COC material protects the magnetic media from corrosion an…
A new Mn(II) coordination polymers based on the 1,10- phenanthroline derivative and flexible dicarboxylate, namely [Mn2(L)2(trans-1,4-chdc)] (1), where L = 11-fluoro-dipyrido[3,2-a: 2′,3′-c]phenazine and trans-1,4-chdc = 1,4-cyclohexanedicar- boxylate, has been successfully synthesized under hydrothermal condition. Co…
Extensive micromagnetic simulations are performed to investigate the impact of the current overshoot amplitude (OSA) on the writer dynamics. The field risetime, dynamic gradient, bubble width, as well as erasure risk due to large stray fields in the neighbouring tracks during the switching are all shown to be very sen…
