CoNd x Fe (2− ) O 4 ( = 0.0–0.05) spinel ferrites are successfully synthesized by mechanical milling using solid‐state reaction. The effects of Nd 3+ ions on structural, microstructure, and magnetic microwave‐absorbing properties samples analyzed. X‐ray diffraction pattern shows a single‐phase cobalt ferrite for all compositions. Refinement the structure that an increase in concentration leads ...

En este trabajo se describe la síntesis de nanoestructuras seleniuro cobre, utilizando técnica microondas y mecanosíntesis. asistida por microondas, el proceso realizó en un horno modificado, para ello, a una solución sulfito sodio le añadió selenio polvo, esta mezcla fue sometida radiación al 40 % formando así selenosulfato luego agregarle acetato cobre manteniendo proporción Cu:Se (1:1) mient...

In our reply to Williamson, we offered models where traditional Gettier cases arise but which differ from Williamson’s models in three related respects: first, non-traditional, fake-barn style Gettier cases do not arise in our models; second, knowledge iterates in our models; and, finally, our models do not have the Moorish consequences of Williamson’s models.1 Predictably, Williamson thinks th...

Organizations often respond to allegations of wrongdoing made by whistle-blowers. Response mechanisms may take several forms, from simply denying the wrongdoing, to offering an apology. This study sought to examine the various response strategies an organization employed after a whistle-blowing incident. Using the whistle-blowing case of Brown and Williamson Tobacco Company, this study sought t...

Evaluation of a new proton sponge, bis-1,1,8,8-(tetramethylguanidino)naphtalene (TMGN), in substituted phenols O-alkylation by methyl iodide in DMF has been studied. Kinetic measurements were performed in N,N-dimethylformamide-d7 and followed by H NMR using stoichiometric amounts of reagents. Plot of the results shows that the reaction follows an almost perfect second order rate law. However th...

The concept of semi-regular sets of matrices was introduced by J. Seberry in "A new construction for Williamson-type matrices", Graphs and Combinatorics, 2(1986), 81-87. A regular s-set of matrices of order m was first discovered by J. Seberry and A. L. Whiteman in "New Hadamard matrices and conference matrices obtained via Mathon's construction", Graphs and Combinatorics, 4(1988), 355-377. In ...

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...

For the first time, low-pressure cold spray (LPCS) process was used to manufacture gallium nitride (GaN) films enhance its photocatalytic properties and decrease manufacturing cost. The deposition behavior of GaN powder on stainless steel substrates investigated. Several specimens, with sparsely deposited agglomerated particles, were prepared under different conditions. Quantitative analysis ev...
