Comparison of the adsorption of cationic blue onto graphene oxides prepared from natural graphites with different graphitization degrees Original Research Article Colloids and Surfaces A: Physicochemical and Engineering Aspects, Available online 6 June 2017, Pages Xuan Jiao, Lingyan Zhang, Yangshuai Qiu, Junfang Guan
Graphical abstract

The typical thickness was approximately 1.180nm for GO-VG, 1.050nm for GO-LG, 0.986nm for GO-FG, and 0.925nm for GO-FG, while the thickness of routinely synthesized single GO sheets ranged from 0.7–1.2nm. Specifically, the sheets with a thickness less than 2nm totaled 60.05% for GO-VG, 69.18% for GO-LG, 74.25% for GO-FG, and 84.79% for GO-AG. | A self-standing macroporous Au/ZnO/reduced graphene oxide foam for recyclable photocatalysis and photocurrent generation Original Research Article Electrochimica Acta, Available online 6 June 2017, Pages Ping She, Shengyan Yin, Qinrong He, Xiaochen Zhang, Kongliang Xu, Yinxing Shang, Xiaoju Men, Shan Zeng, Hang Sun, Zhenning Liu | A hyaluronic acid/graphene oxide hydrogel for enhanced ex vivo expansion of cord blood-derived CD34+ cells Materials Letters, Available online 6 June 2017, Pages Wenzhen Guo, Xiuwei Pan, Yuanhao Zhang, Haibo Cai, Weian Zhang
Graphical abstractHA/GO hybrid hydrogels with adjustable mechanical property were prepared via an in-situ free-radical polymerization, and then utilized for ex vivo expansion of CD34+ cells. Subsequently, the influence of physical property of the hydrogels on ex vivo expansion of CD34+ cells was evaluated.
