Hydrothermal and sol-gel synthesis methods have been used to prepare nano-particulate hydroxyapatite (HA) powders for detailed characterisation. Bulk elemental analysis data are compared from X-ray diffraction, X-ray fluorescence and Fourier transform infrared spectroscopy. These show the presence of secondary phases in the sol-gel powders which can be attributed to evaporative loss of precursor phosphite phases during specimen preparation and breakdown of the primary HA phase during calcination. Only the primary HA phase is detected in the hydrothermally prepared powder. In addition, Ca/P ratios of each powder are determined at the particle level using transmission electron microscopy with energy dispersive X-ray spectroscopy (TEM-EDX), having first established a threshold electron fluence below which significant electron-beam-induced alteration of the composition of HA does not occur. The TEM-EDX results show a greater compositional variability of particles from the sol-gel preparation route compared to the hydrothermal route. Overall it is the combination of the analysis techniques that shows the hydrothermal synthesis route produces near- stoichiometric, single phase, hydroxyapatite.

“低科技”老爸史蒂夫·乔布斯（英文）

大学英语 2015年第2期 37-40页

作者： Nick bilton 武玉莲北京外国语大学

When Steve Jobs was running Apple,he was known to call journalists to either pat them on the back1for a recent article or,more often than not2,explain how they got it wrong.I was on the receiving end of a few of those calls.3But nothing shocked me more than something Jobs said to me in late 2010 after he had finished chewing me out4for something I had written about an i Pad shortcoming.

几百万人观看了一个机器人降落在24784万千米外的火星上,它用自己的Twitter账号分享了视频、照片和状态更新.我也和一个机器人见了一面.我还与机器人一起吃了晚饭——就在硅谷.晚宴是在门洛帕克的一家机器人科技公司Willow Garage,目的是向记者们介绍该公司正在研发的机器人.吸引众人注意的主要是PR2,它可以捡起东西、叠好衣物、开门、把杯子和盘子以及其他小物品递给人们.PR2的动作很让人吃惊,售价也同样令人咋舌:全功能版40万美元.
