1	利用飞秒双光子光电子发射研究GaAs(100)的自旋动力学过程显示文摘超短激光技术的发展为研究材料中的超快光动方学过程提供了重要的实验手段,也使得人们能够更为深入地研究电子的自旋动力学行为.GaAs(100)表面由于费米钉扎而会导致能带弯曲,位于该区域的电子及其自旋特性将会明显不同于体相材料中的情况.利用时间分辨和自旋分辨的双光子光电子发射技术研究了p型掺杂GaAs(100)表面的电子极化动力学过程.结果表明,由费米钉扎而引起的能带弯曲明显影响电子的自旋弛豫过程,从实验上观察到了GaAs(100)表面能带弯曲区域的电子自旋翻转时间存在近2个量级的差异(从几纳秒到几十皮秒),基于电子_自旋交换相互作用的BAP机理在自旋弛豫过程中起着主导作用.	郭立俊 Jan-Peter Wüstenberg Andreyev Oleksiy Michael Bauer Martin Aeschlimann	2005	物理学报2005，54，7：	7
2	Physical and Chemical Transformation of Hydroxyapatite Nanoparticles in Aqueous Sol after Preparation and in vitro显示文摘The co-precipitation method followed by ultrasound and heat treatment is a common way to prepare below 100 nm sized hydroxyapatite nanoparticles for biomedical studies and applications. The size and pH value of the obtained calcium phosphate nanoparticles in aqueous sol have a strong impact on the interactions with cells and tissue. The physical and chemical properties of material samples for in vitro and in vivo studies are often assumed to remain constant from the time after fabrication to the actual use. Only little attention is paid to eventual changes of the material over time or due to the different in vitro conditions. In this study, the physical and chemical transformation of calcium phosphate nanoparticles after preparation and in vitro was investigated. As the result showed, dispersed nano sized amorphous calcium phosphate precipitation as well as crystallized hydroxyapatite nanoparticles continue to crystallize even when kept at 4 ℃ leading to declining pH values and particle sizes. Due to the pH buffer in the medium the pH value of the cell culture remained stable after adding 20% nanoparticle sol in vitro. However, hydroxyapatite nanoparticles immediately became unstable in the presents of cell culture medium. The resulting loose agglomerations showed a size of above 500 nm.
