A series of boron nitride nanotubes (BNNTs)/ carbide (B4C) composite ceramics were prepared using spark plasma sintering (SPS) technology, which uses B4C powders as the matrix and BNNTs toughening phase. X-ray diffraction (XRD) scanning electron microscope (SEM) then used to characterize ceramic samples. The effects temperature, content, particle size on microstructure mechanical properties inv...

in this research, b4c-ni cermet coating was sprayed on the surface of 4130 steel from b4c and ni feed-stockpowders using high velocity oxy-fuel (hvof) method. in order to characterize the tribological behavior of thecoating, ball on disk wear tests were done at the ambient temperature and under the loads of 1, 3 and 5 n.phase analysis of the coating after spraying was studied by x-ray diffracto...

5-Fluorouracil (5-FU) is an anticancer drug. In this work, we have investigated the electronic properties and topological analysis of interaction between 5-FU and carbon nanocone and BN nanocone. The structural stability of isomer complexes of 5-FU with carbon nanocone and BN nanocone have been investigated for two position of interactions. We have found that the most stable complexes are forme...

In the current study, effect of different B4C additions (0, 2.5, 5, and 10 wt%) on microstructural, solidification behavior, mechanical, tribological properties Al-20%Mg2Si composite were studied by means scanning electron microscopy (SEM) equipped with energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), Vickers hardness, tensile, dry sliding wear tests. The cooling curve thermal ana...

Cancer detection in early stage using a powerful and noninvasive tool is of high global interest. In this experiment, a small-molecular-weight glucose based derivative of Gd3+-1-(4-isothiocyanatobenzyl) diethylene tri amine penta acetic acid (Gd3+-p-SCN-Bn‐DTPA‐DG) as a novel potential MR imaging contrast agents was synthesized. Gd3+-p-SCN-Bn‐DTPA‐DG was synthesized with reacting of Glucosamine...
