Toxicity and transformation of graphene oxide and reduced graphene oxide in bacteria biofilm.
Zhiling Guo,Changjian Xie,Peng Zhang,Junzhe Zhang,Guohua Wang,Xiao He,Yuhui Ma,Bin Zhao,Zhiyong Zhang +8 more
TL;DR: Graphene oxide results showed that rGO were oxidized to GO which can enhance the bacterial growth which deduced that the elimination of the toxicity of rGO at mature phase was contributed by EPS protection and the oxidation of r GO.

Xylem and Phloem Based Transport of CeO2 Nanoparticles in Hydroponic Cucumber Plants
Yuhui Ma,Xiao He,Peng Zhang,Zhiyong Zhang,Yayun Ding,Junzhe Zhang,Guohua Wang,Changjian Xie,Wenhe Luo,Jing Zhang,Lirong Zheng,Zhifang Chai,Ke Yang +12 more
TL;DR: The detection of CeO2 or its transformation products in the xylem sap, shoots, and BS roots indicates that Ce was transported as a mixture of Ce(IV) and Ce(III) from roots to shoots through xyleM, while it was transported almost only in the form of Ce O2 from shoots back to roots through phloem.

Phytotoxicity, uptake and transformation of nano-CeO2 in sand cultured romaine lettuce
Peng Zhang,Yuhui Ma,Shutong Liu,Guohua Wang,Junzhe Zhang,Xiao He,Jing Zhang,Yukui Rui,Zhiyong Zhang +8 more
TL;DR: X ray absorption near edge spectroscopy results indicate that release of Ce3+ played a critical role in the toxicity nCeO2, indicating that releaseof Ce3+, which can be converted to toxic nitrite in humans thereby posed risk to human health.

Trophic transfer and transformation of CeO2 nanoparticles along a terrestrial food chain: influence of exposure routes
Yuhui Ma,Yao Yao,Jie Yang,Xiao He,Yayun Ding,Peng Zhang,Junzhe Zhang,Guohua Wang,Changjian Xie,Wenhe Luo,Jing Zhang,Lirong Zheng,Zhifang Chai,Yuliang Zhao,Zhiyong Zhang +14 more
TL;DR: The trophic transfer and transformation of CeO2 nanoparticles through a simulated terrestrial food chain were investigated using a radiotracer technique and X-ray absorption near edge structure and results show that both assimilation efficiencies (AEs) and food ingestion rates of Ce are greater for the Trophic (indirect) exposure.

Effects of foliar applications of ceria nanoparticles and CeCl3 on common bean (Phaseolus vulgaris).
Changjian Xie,Yuhui Ma,Jie Yang,Boxin Zhang,Wenhe Luo,Sheng Feng,Junzhe Zhang,Guohua Wang,Xiao He,Zhiyong Zhang +9 more
TL;DR: X-ray absorption near edge structure (XANES) analysis of the leaf samples revealed that both ceria NPs and Ce3+ ions kept their original chemical species after foliar applications, suggesting the observed effects of ceria Ceria NPS and Ce 3+ ions on the plants were probably due to their nano-specific properties and ionic properties respectively.
