Fast and uniform growth of high-quality graphene on conventional glass is of great importance for practical applications of graphene glass. We report herein a confined-flow chemical vapor deposition （CVD） approach for the high- efficiency fabrication of graphene glass. The key feature of our approach is the fabrication of a 2-4 μm wide gap above the glass substrate, with plenty of stumbling blocks; this gap was found to significantly increase the collision probability of the carbon precursors and reactive fragments between one another and with the glass surface. As a result, the growth rate of graphene glass increased remarkably, together with an improvement in the growth quality and uniformity as compared to those in the conventional gas flow CVD technique. These high-quality graphene glasses exhibited an excellent defogging performance with much higher defogging speed and higher stability compared to those previously reported. The graphene sapphire glass was found to be an ideal substrate for growing uniform and ultra-smooth aluminum nitride thin films without the tedious pre-deposition of a buffer layer. The presented confined- flow CVD approach offers a simple and low-cost route for the mass production of graphene glass, which is believed to promote the practical applications of various graphene glasses.

五四时期,以蔡和森、向警予、李维汉、李立三、罗学瓒、张昆弟、李富春、蔡畅、萧三为代表的湖南青年,怀抱“改造中国与世界”的志向,引导了留法勤工俭学运动向俄国十月社会主义革命的方向发展。其中,蔡和森是最早提议建党并取名“中国共产党”的人,并建议新民学会在法国的分支“工学世界社”更名“少年共产党”。正因为有蔡和森等湖南青年在海外从事建党实践,毛泽东评价他们与国内建党的创始人一样,都是中国共产党早期组织在海外的创始人。
