Memory Effects in Compound-Specific D/H Analysis by Gas Chromatography/Pyrolysis/Isotope-Ratio Mass Spectrometry
Compound-Specifi c D/H Analysis Memory Effects
2014/4/8
Compound-specific analyses of lipid D/H ratios often
encounter ranges of 300‰ or more, and experiments
using D-enriched water to study fractionations often
extend the range up to 1000‰. Here ...
铝/氟比对改性尖晶石锰酸锂性能的影响（Influence of the n(Al)∶n(F) Ratio on Performance of Modified LiMn2O4 Materials）
尖晶石LiMn2O4 锂离子电池 高温固相反应
2010/8/18
采用草酸铝、氟化锂与尖晶石LiMn2O4进行高温固相反应，制备出改性尖晶石LiMn2O4材料。对材料进行了XRD、SEM分析及电性能测试，结果表明，改性材料均基本保持了尖晶石主体结构，晶格常数随n(Al)∶n(F)比例的增大而减小;Al3+、F-的引入可以引起材料颗粒表面形貌的变化，产生规则结晶，而颗粒表面结晶的大小受n(Al)
Determination of the H3 Factor in Hydrogen Isotope Ratio Monitoring Mass Spectrometry
Hydrogen Isotope Ratio Monitoring Mass Spectrometry
2014/4/8
The H3 factor, K, is a parameter required in highprecision, mass spectrometric analyses of hydrogen isotopic abundances. When H2 is used as the sample gas,
