水热条件下钛酸钡粒子的自组装

, 2006
研究了水热条件下钛酸钡粒子的聚集状态形成和形貌变化。首先以钛酸四丁酯为钛源,醋酸钡为钡源,通过水热反应制备了特殊的聚集状态的钛酸钡。扫描电子显微镜的表征结果表明,这些特殊聚集状态的钛酸钡是由更小的钛酸钡粒子自组装而形成的,可以通过调变水热反应参数实现对产物的聚集状态的调控 ...

用激光激发的荧光等离子体中原子和离子空间分布模型

, 1985
等离子体作为强有力的原子化器、离子化器和激发器已经广泛地用于光谱化学分析中。有些作者已经研究过等离子体的温度空间分布、电子数密度以及分析物原子(离子)在等离子体的空间分布。大多数作者,使用发射强度测量的方法得到空间模型,但是,要求Abel转换技术,先变换成横向后再变换成空间模型。这种模型不仅受基态原子(离子)的影响,而且也受随等离子体温度分布而指數变化的Boltzman因子的影响。1980年 ...
