Opis:
Based on the embedded atom method a molecular dynamics simulation technique has been used to study the glass formation and atomic short range order in Pd-Ni binary alloy. By using radial distribution functions and Honeycutt-Andersen pair analysis methods, the structural development of this alloy is studied by quenching from the liquid at two different cooling rates and under 0 and 5 GPa pressures. The results show that the variation of local atomic bonded pairs is of great importance to understand the glass formation process and increase of the number of the ideal icosahedra under high pressure contributes to more ideal glass formation of model alloy.

Opis:
Cerium, the most abundant rare earth element, and boron containing mineral (lithium tetraborate pentahydrate) were used for synthesizing rare earth borates. Alternatively, for preparing rare earth borates, hydrothermal technique can be used. The non-stoichiometric cerium and boron containing compounds were synthesized by hydrothermal method using cerium sulphate and lithium tetraborate pentahydrate in appropriate molar ratio. Characterizations were done by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy/energy dispersive X-ray analysis, and thermogravimetric/differential thermal analysis.

Opis:
$CeVO_4$ (ICDD: 12-757) was synthesized by microwave-assisted method by using cerium sulphate and vanadium (V) oxide in an appropriate molar ratio. Characterizations were done by X-ray diffraction, Fourier transform infrared spectroscopy, ultraviolet spectrophotometry and thermogravimetric/differential thermal analysis. The material is crystallized in tetragonal system with unit cell parameters a = 7.399 Å and c = 6.496 Å and space group I41/amd(141).

Opis:
$Co_3V_2O_8$ is a member of kagomé staircase oxides, represented by general formula $M_3V_2O_8$ (M = Ni, Co, Mn). It attracted great attention due to strong magnetic anisotropy, magnetic phase transition, genuine macroscopic quantum effects, strong quantum fluctuations, low-temperature ferroelectricity, field-induced magnetic transitions, complicated phase diagram and displays long-range magnetic order because of geometrical frustration. Different routes to prepare the frustrated magnetic material was reported such as floating zone technique and conventional high temperature method. $Co_3V_2O_8$ (International Centre for Diffraction Data (ICDD): 16-675) was synthesized with $Co_3O_4$ (ICDD: 80-1536) as binary phase by microwave assisted preparation using $Co(NO_3)_2 ·6H_2O$ and $NH_4VO_3$. The synthesized material was characterization by powder X-ray diffraction, the Fourier transform infrared spectroscopy, and thermogravimetric-differential thermal analysis.

Opis:
$B_4C$ ceramics were fabricated by spark plasma sintering technique at 1700°C-1800C for 5 min under applied pressure of 50 MPa under vacuum atmosphere. Two different grades of $B_4C$ powder from H.C. Starck Company namely HP grade and HS grade were used in all related experiments. Effect of sample geometry and dimensions as well as sample thickness on sintering parameters were analyzed. Samples having 5 mm thickness and 50 mm diameter, 8 mm thickness in circular geometries and 50 × 50 square cross-section, 8 mm thickness were fabricated. Using the powder, which provided the densest sample, yttrium oxide $(Y_2O_3)$ was added, mixed and sintered. Optimization of SPS method production parameters for pure $B_4C$ samples and $B_4C$ samples with 5 wt% yttrium oxide additive were accomplished. The effect of geometry on density, Vickers hardness, fracture toughness, and microstructure were examined. The hardness and fracture toughness values of the samples were evaluated by the Vickers indentation technique.
