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...

In this research, novel functionally graded Ni-P coating was deposited with electroless process. The content of phosphorus was controlled to change gradual through the thickness of the coating. During the plating, bath temperature and pH were changed at specified intervals to obtain functionally graded structure. To compare the properties of functionally graded coating with Ni-P single-layer co...

in this study a special type of silicoaluminophosphate with opal structure (opal-sapo) was prepared under microwave condition using tetraethylorthosilicate (teos), triethanolamine (tea), aluminiumisopropoxid and phosphoric acid 85%. the product was characterized by x-ray diffraction (xrd), thermogravimetric (tga) and fourier infrared spectroscopy (ftir).the crystalline product showed a good act...
