Zn0.98-xMg0.02BxO nanoparticles with various dopant ratios (x = 0.00 - 0.05 increments of 0.01) were grown by using the sol-gel technique. The samples synthesized and X-ray diffraction, scanning electron microscopy, optical reflectivity, dispersive analyses used to obtain structural, electronic, properties, respectively. Williamson–Hall procedure was utilized structural properties. energy bandg...

We obtain new combinatorial formulae for modified Hall–Littlewood polynomials, for matrix elements of the transition matrix between the elementary symmetric polynomials and Hall-Littlewood’s ones, and for the number of rational points over the finite field of unipotent partial flag variety. The definitions and examples of generalized mahonian statistic on the set of transport matrices and dual ...

We employ tools from the fields of symbolic computation and satisfiability checking— namely, computer algebra systems and SAT solvers—to study the Williamson conjecture from combinatorial design theory and increase the bounds to which Williamson matrices have been enumerated. In particular, we completely enumerate all Williamson matrices of even order up to and including 70 which gives us deepe...

Tin dioxide (SnO2) nanoparticles doped with varying concentrations of copper were synthesized and characterized using various techniques. The X-ray diffraction analysis revealed that all undoped SnO2 samples had a rutile-type tetragonal structure. average crystalline size the estimated Scherrer’s formula Williamson–Hall plot decreased as dopant concentration increased. Images from scanning elec...

Stannous oxide (SnO) micro sheets were successfully synthesized by the hydrothermal alkaline solution method and characterized X-ray diffraction, scanning electron microscopy, transmission energy-dispersive spectroscopy, Brunauer-Emmett-Teller (BET) techniques. BET analysis confirmed a mesoporous structure with 33.8944 m2 g−1 specific surface area an average pore diameter of 6.488 nm. The resis...

Scanning Hall Probe Microscopy (SHPM) is a scanning probe microscopy technique developed to observe and image magnetic fields locally. This method is based on application of the Hall Effect, supplied by a micro hall probe attached to the end of cantilever as a sensor.  SHPM provides direct quantitative information on the magnetic state of a material and can also image magnetic induction under a...

In the case of optical sensors such as Surface Plasmon Resonance (SPR) sensor, Fe3O4 nanoparticles play a role to boost signal however they can increase detection sensitivity biosensor. For this application, properties need be studied. The are described in terms their constants. Therefore, work was purposed study effect particle size and lattice strain on constants nanoparticles. Samples were s...

Received 10 April 2015 Accepted 11 October 2015 Available online 30 September 2015 In this work, structural and magnetic properties of the LaMnO3+δ compound prepared by citrate precursor method and annealed in the presence of oxygen are investigated. The structural characterization of LaMnO3+δ by X-ray powder diffraction and X‟pert package and Fullprof program provides evidence for a rhombohedr...

The effect of Zn-doping in CoFe2O4 nanoparticles (NPs) through chemical co-precipitation route was investigated in term of structural, optical, and magnetic properties. Both XRD and FTIR analyses confirm the formation of cubic spinel phase, where the crystallite size changes with Zn content from 46 to 77 nm. The Scherrer method, Williamson-Hall (W-H) analysis, and size-strain plot method (SSPM)...
