| 1 | Modification on the tribological properties of ceramics lubricated by water using fullerenol as a lubricating additive显示文摘It is necessary to modify the running-in process for the application of ceramics using water as a lubricant in real conditions because ceramics sliding in water are characterized by a running-in period with severe friction and wear.Fullerenol,a kind of highly water-soluble nanoparticle,was synthesized and then used to ameliorate the tribological properties of Si 3 N 4 sliding against Al 2 O 3 in pure water.With the addition of fullerenol,the running-in period was shortened from 30 min to 100 s at a speed of 250 mm/s.The speed threshold above which ultralow friction can be obtained in a short time was expanded from 450 mm/s to 80 mm/s.Meanwhile,the load-carrying ability of water film was increased.The role of fullerenol was discussed based on observation of the wear scar by an optical interferometer and XPS characterization of the tribo-film on the wear track. | LIU YuHong WANG XiaoKang LIU PengXiao ZHENG JunPeng SHU ChunYing PAN GuoShun LUO JianBin | 2012 | Science China(Technological Sciences)2012，55，9： | 9 |
| 2 | Tunable tribological properties in water-based lubrication of water-soluble fullerene derivatives via varying terminal groups显示文摘In this paper,three kinds of water-soluble fullerene derivatives were synthesized via electrophilic addition reaction and cycloaddition reaction,respectively.The chemical composition characterizations of these derivatives indicated the successful preparation of C60(OH)x,C60(C(COOH)2)x and C60(OH)x(NHCH2COOH)y fullerene derivatives.The aggregation and morphology characterizations showed that the three kinds of derivatives had an ideal spherical aggregating structures and excellent dispersibility in water,especially C60(OH)x and C60(C(COOH)2) x.The lubrication performance of the fullerene derivatives acted as lubricant additives were investigated at different concentrations in the range of 0-1 wt%.The results indicated that the addition of polyhydroxyl and carboxylic derivatives could improve the lubrication properties,which led to the reduction of wear to about 40% at most.It is attributed that the optimized substitutions of fullerene molecules may be of benefit to their distribution properties and lubricating behaviors in water based lubrication. | LIU YuHong LIU PengXiao CHE Lu SHU ChunYing LU XinChun | 2012 | Chinese Science Bulletin2012，57，35： | 3 |
| 3 | Oral nano-antioxidants improve sleep by restoring intestinal barrier integrity and preventing systemic inflammation显示文摘Sleep deprivation(SD)is a severe public health threat that can cause systemic inflammation and nerve damage.Few effective and side-effect-free drugs are available to address SD.However,the bidirectional communications between the brain and gut provide new strategies for anti-SD therapeutics.Here we explored oral delivery of fullerene nano-antioxidants(FNAO)in the SD model to improve sleep by regulating abnormal intestinal barrier and systemic inflammation via the brain-gut axis.SD caused excessive reactive oxygen species(ROS)production and hyperactive inflammatory responses in the intestines of zebrafish and mouse models,leading to disturbed sleep patterns and reduced brain nerve activity.Of note,based on the property of the conjugatedπbond of the C_(60)structure to absorb unpaired electrons,oral FNAO efficiently reduced the excessive ROS in the intestines,maintained redox homeostasis and intestinal barrier integrity,and ameliorated intestinal and systemic inflammation,resulting in superior sleep improvement.Our findings suggest that maintaining intestinal homeostasis may be a promising avenue for SD-related nerve injury therapy. | Zhanfeng Wu Lei Liu Lei Li Xinran Cao Wang Jia Xiaodan Liao Zhongpu Zhao Hedong Qi Guoqiang Fan Huiqiang Lu Chunying Shu Mingming Zhen Chunru Wang Chunli Bai | 2023 | National Science Review2023，10，12： | 1 |
