Nitrogen-doped carbon quantum dots(C-dots)were synthesized via facile and one-step hydrothermal approach from soy flour with NaOH assisted reaction,and the C-dots obtained had stronger fluorescence than that of C-dots without added NaOH.The as-prepared C-dots show good photostability at room temperature,under UV irradiation or in high ionic strength aqueous solution,high sensitivity towards pH,polarity of the solvent and ferric ion.Furthermore,the as-made C-dots can be used as fluorescence probes for detection of ferric ion.This work offers a simple approach to produce high quality C-dots from cheap and easily available soy flour.

吸烟行为是吸烟者多个抽吸参数的综合描述,同时受社会因素以及卷烟特征的影响.为了解不同焦油量吸烟者的吸烟行为,本研究采用分子流行病学方法,即通过流行病学调查和生物标志物测定相结合的方法,对不同焦油量吸烟者的吸烟行为及相关影响因素进行研究.在对435名18岁及以上居民的吸烟行为进行横断面调查的基础上,按照吸烟者抽吸的卷烟焦油量,将435名居民分为非吸烟组,低焦油组1～6mg/支,中焦油组7～8mg/支
