The present paper presents SEM and Auger structural studies of the materials and provides further evidence that the oxygen and boron distribution influences pinning and the SC characteristics of MgB2-based materials.
The HP-synthesized and sintered MgB2-based materials usually contain higher borides with X> 8-12.
In the materials prepared at 1050 oC local Mg-B-O inclusions (white in Figs. 1f, i) are forming.
All materials prepared at 1050 oC demonstrated a surprisingly high connectivity (80-87 %), but the magnetically estimated critical current density, jc, of in-situ SPS-prepared materials (from Mg:2B) with 98 % connectivity was somewhat lower than that of HP-synthesized materials with 87% connectivity.

Much of the pioneering work using the DEM simulation to simulate the behavior of granular materials was performed by Cundall and Strack[18, 19].
The DEM simulation has been extensively developed over the years to evaluate the dissipative properties of granular materials.

Red-emitting phosphors Ca0.7-x Eu0.3Znx MoO4（X=0, 0.02, 0.04, 0.06, 0.08, 0.1）were fabricated by a solid state reaction method using (NH4)6Mo7O24·4H2O, CaCO3, Eu2O3 and ZnO as raw materials at the temperature of 600°C, 700°C, 750°C, 800°C, 850°C and 900°C, respectively.
Molybdenum tungstate plays a very important role as optical material.
Experimental procedure A series of samples were synthesized by solid state reaction using (NH4)6Mo7O24∙4H2O, CaCO3, Eu2O3, ZnO as raw materials.
Firstly, stoichiometrically weighed raw materials were mixed with a small amount of absolute ethyl alcohol and ground in an agate mortar.
