| 1 | Effect of alumina content and heat treatment on microstructure and upconversion emission of Er^(3+)ions in oxyfluoride glass-ceramics显示文摘The effect of alumina content and heat treatment temperature and time, on microstructure and Er3+ (0.5 mol.%) emission of oxy-fluoride glass-ceramics were investigated in this research. Two values of 1.8 (SA1.8Er0.5) and 2.18 (SA2.18Er0.5) were selected in this re-search for SiO2/Al2O3 ratio. According to DTA results, precursor glasses were heat treated at 630, 660 and 690 °C for 4 h and some glasses were also heat treated at 630 °C for 48 and 72 h. The results indicated that alumina content had significant effect on phase separation and vis-cosity of the glasses. Therefore the size, size distribution, and volume concentration of nano CaF2 crystals which precipitated during the heat treatment depended on alumina content of the glass. Due to the much smaller size of the precipitated CaF2 crystals in the glasses of low alumina content, these samples maintained excellent transparency and had narrower crystal size distribution than the high alumina glasses. The crystal size was increased markedly with the temperature increasing from 630 to 690 °C. On the other hand a slight increase was observed in the crystal size by raising the heat treatment time in both glasses. Results indicated that in low alumina content glass (SA2.18Er0.5) the size of CaF2 nanocrystals was controlled in one order of magnitude. The increase of heat treatment time and temperature led to the incorporation of Er3+ ions into CaF2 crystalline phase, increasing significantly the upconversion intensity. After heat treatment at 690 ℃ for 4 h, atomic force microscope (AFM) re-vealed the development of small crystals with an average size of 80 and 30 nm in SA1.8Er0.5 and SA2.18Er0.5 samples, respectively. | Mohammad Hasan Imanieh Bijan Eftekhari Yekta Vahak Marghussian Inocencio Rafael Martin Benenzuela Alberto Hernandez Creus Saeed Shakhesi Esmaeil Eslami | 2012 | Journal of Rare Earths2012，30，12： | 3 |
| 2 | Toxoplasmosis among pregnant women:High seroprevalence and risk factors in Kinshasa,Democratic Republic of Congo显示文摘Objective:To determine the seroprevalence of toxoplasmosis in pregnant women,as well as the proportion of acutely infected and risk factors in the Democratic Republic of Congo.Methods:Thirty maternities in Kinshasa were randomly selected and women attending antenatal consultation were invited to participate.They were interviewed with a structured questionnaire about known risk factors(age,meat consumption,contact with soil,and presence of cat)and a venous blood sample was taken.Sera were analysed for total immunoglobulins(Ig)by VIDAS Toxo Competition using Enzyme Linked Fluorescent Assay.IgM was determined by VIDIA Toxo IgM and IgG avidity by VIDAS Toxo IgG avidity.Results:A total of 781 women were included.Median age was 28 years old(IQR:8.S).And 627women(80.3%;95%CI:77.5-83.1)were found to be positive to total Ig and 17 out of 387(4.4%;95%CI:2.3-6.4)were positive to IgM.IgC avidity was low for 2(11.8%)women,intermediate for 2(11.8%)and high for 13 women(76.4%).There was no statistically significant association between Toxoplasma gondii infection and any risk factors assessed.Conclusion:In Kinshasa,toxoplasmosis endemicity is highly prevalent.One woman out of twenty five had a recent toxoplasmosis infection and 20%were not protected against primoinfection,indicating a need for measures to prevent and control toxoplasmosis during pregnancy. | Doudou Yobi Renaud Piarroux Coralie L'Ollivier Jacqueline Franck Hypolite Situakibanza Hypolite Muhindo Patrick Mitashi Raquel Andreia Inocencio da Luz Marc Van Sprundel Marleen Boelaert Jean-Pierre Van Geertruyden Pascal Lutumba | 2014 | Asian Pacific Journal of Tropical Biomedicine2014，4，1： | 2 |
