size of live cells declined significantly. Microcystin-LR (MC-LR), the most common and toxic cyanotoxins produced by A. flosaquae, was de-tected and the highest content of MC-LR was observed in 10 mg......
) and compact-fine Fe3C stick and patch (mean size 100-300 nm), respectively. The wear resistance of the experimental steel could be improved remarkably by plasma RE nitrocarburizing. The nitrocarburized......
diffraction (XRD) were used to examine the effects of a Sr-Y composite modifier on the microstructure of A356 alloy. After adding Y to A356, YAl 3 compounds formed, and the size of the α (Al) crystal nucleus......
of La. With the addition of appropriate amount of La, the crystallite size of CuO was decreased and the dispersion of Cu on the surface was enhanced, which resulted in the increased conversion of CO2......
-programmed reduction (H2-TPR). The presence of H2O2 was found to have profound effect on powder properties such as surface area, crystallite size of the samples. It was also shown that the addition of H2O2......
:Eu3+sample was monoclinic phase characterized by using X-ray diffraction(XRD).The particle size was about 80 nm observed by field emission scanning electron microscopy(FE-SEM).The photoluminescence......
,small domain size and the pinning effect of C or CNTs-rich regions.The magnetic properties of SmCo6.9Hf0.1(CNTs)0.05ribbons reached Hc=12.5 kOe,Mr=57.0 emu/g and Mr/M2 T=0.788.关键词:......
).It was indicated that the MDC method could prepare the ultrafine Ce-based oxide nanoparticles whose the crystal lattice were perfect,and the BET surface area and average crystal size of the ultrafine......
oxidation was affected by not only the redox properties of catalysts but also the size of Pd particle, and large Pd particles possessed higher TOF value of C3H8 oxidation, with the highest value(0.125......
. The TEM image showed that the size of the particle was 12 nm using the scherer formula. The XPS result showed that the element Sm was doped and Ag was loaded inorganic nanomaterials successfully. Sm......
