nanoparticles of coordination polymer [co2(pydc)2(h2o)6]n.2n h2o [h2pydc = pyridine-2,5-dicarboxylic acid] have been synthesized by sonochemical method and characterized by elemental analysis, infrared spectroscopy, powder x-ray diffraction, scanning electron microscopy, dls particle size analysis and tga/dta. the structure of single crystalline coordination polymer developed from nanosized coo...

Production of Fe-C alloy powders by mechanical alloying was studied. Fe and graphite elemental powder mixtures containing 0.8 and 1.5wt.% graphite were mechanically alloyed using a planetary ball mill. The structural changes of powder particles during mechanical alloying were studied by x-ray diffractometery, scanning electron microscopy and microhardness measurements. For both compositions, me...
