| 1 | Lubricating a bright future:Lubrication contribution to energy saving and low carbon emission显示文摘Both the academic society and the industry are hunting for new energy forms for the future.However,the world should not forget the conventional technologies that contribute to the sustainable society by technical innovations.Among them,lubrication plays a significant role in energy saving and in low CO2emission by increasing the fuel efficiency and by prolonging the service life of machines.With the advance of novel synthetic approaches,and nanoscience and technologies,novel lubrication oils and additives and their formulations are being developed to reduce friction and wear,and novel surface treatment routes and surface coatings are invented and provide more efficient lubrication.These technologies create tremendous chances for machines to work more efficiently with low energy consumption.Here we review the recent progresses and challenges associated with some novel lubrication techniques that include novel surface treatment(such as texturing,high-performance nanocomposite coatings,adapting coating),tribology design(solid and liquid lubrication),energy-conserving engine oil and novel lubricants and formula(such as ionic liquids,low S,P content additives)which are to be adopted to enhance the fuel efficiency to achieve energy saving and low carbon emission.There is increased demand to replace fossil lubricants by degradable green lubricants.Specially designed coatings can reduce drag significantly during navigation of both airplanes and ships.All these aspects will be also reviewed in the paper. | CAI MeiRong GUO RuiSheng ZHOU Feng LIU WeiMin | 2013 | Science China(Technological Sciences)2013，56，12： | 22 |
| 2 | Phytolith carbon sequestration in bamboos of different ecotypes:a case study in China显示文摘Occlusion of carbon(C) within phytoliths(Phyt OC) is becoming one of the most promising terrestrial C sequestration mechanisms. This study explored the production of Phyt OC within 35 bamboo species belonging to three ecotypes using methods of microwave digestion. The aim of this study is to explore the present and potential C sequestration rate within phytoliths of bamboo species from three ecotypes. Phyt OC content in bamboos of three ecotypes ranges from 0.07 % to 0.42 %. The mean Phyt OC production flux decreases as: clustered bamboo(0.050 ±0.016 t CO2ha-1a-1) & mixed bamboo(0.049 ± 0.016 t CO2ha-1a-1) [ scattered bamboo(0.038 ± 0.020 t CO2ha-1a-1). The phytolith carbon sequestration in Chinese bamboo is estimated to be 0.293 ± 0.127 Tg(1 Tg =1012g) CO2a-1; approximately 75 %, 3 %, and 22 % of which is contributed from scattered, mixed and clustered bamboo, respectively. Taking the Phyt OC production flux of 0.18 ± 0.12 t CO2ha-1a-1and current annual area increasing rate of 3 %, global bamboo phytoliths wouldsequester 11.9 ± 7.9 Tg CO2a-1by 2050. Consequently,bamboo forests have significant potential to mitigate the increasing concentration of atmospheric CO2 by maximizing Phyt OC production flux and expanding bamboos. | Beilei Li Zhaoliang Song Hailong Wang Fengshan Guo Renyi Gui Xiaomin Yang Ruisheng Song | 2014 | Chinese Science Bulletin2014，59，34： | 2 |
| 3 | E3泛素连接酶MG53在胰岛素抵抗及代谢性疾病中的作用显示文摘泛素是一种存在于大多数真核细胞的小蛋白,它的主要功能是标记需要分解掉的蛋白质;附有泛素的蛋白质在桶状蛋白酶的作用下会发生降解。蛋白质泛素化是后翻译修饰的一种常见形式,这一过程是一个三酶级联反应,即需要泛素活化酶(E1)、泛素交联酶(E2)和泛素连接酶(E3)的参与。其中E3泛素连接酶能识别特定的需要被泛素化的靶蛋白,并催化泛素分子转移到靶蛋白上。Mitsugumin53(MG53)是一种存在于人类、鼠类及其他哺乳动物体内的天然蛋白质,它特异性表达于骨骼肌和心脏中,是一种含三个特定模序结构的家族蛋白。该家族蛋白能结合在细胞不需要的蛋白质上,并将其降解。 | Ruisheng Song Wei Peng Yan Zhang Fengxiang Lv Hong-KunWu Jiaojiao Guo Yongxing Cao Yanbin Pi Xin Zhang Li Jin Mao Zhang Peng Jiang Fenghua Liu Shaoshuai Meng Xiuqin Zhang Ping Jiang Chun-Mei Cao Rui-Ping Xiao | 2013 | 中南医学科学杂志2013，41，5： | 0 |
| 4 | Ultralow-adhesion icephobic surfaces:Combining superhydrophobic and liquid-like properties in the same surface显示文摘As a ubiquitous natural phenomenon,ice/frost formation on solid surfaces have adverse effects on many commercial and residential activities.Icephobic surfaces feature low ice adhesion strengths(<100 kPa)can passively retard ice formation and ease ice removal.Superhydrophobic surfaces and liquid-lubricating surfaces are two prevailing categories of icephobic surfaces.However,their long-term stability is relatively poor,and the ice adhesion strengths are not low enough for passive removal of small ice crystals(e.g.,frosts)from the surfaces.Herein,we combine the superhydrophobic and liquid-like properties in one surface to obtain durable icephobic surfaces with extremely low ice adhesion strengths(about 0.035 kPa).Ices and frosts can be removed from the surface under the action of gravity or gas purge.These surfaces are prepared based on surface nanoconical structure and covalently-grafted liquid-like perfluorinated polyether(PFPE)coating,which show synergy effects on suppressing icing and frosting by promoting expulsion of subcooled condensate droplets from the nanotexture and decreasing ice adhesion strengths.The icephobic surfaces show significantly better durability compared to lubricant-impregnated textured surfaces.Our results provide a new avenue to design passive anti-icing/anti-frosting surfaces for a wide range of applications where surfaces are exposed to humid and low-temperature environments. | Mengling Ouyang Ruisheng Guo Yue Fan Yi Zhou Chengjiao Wu Liwei Chen Shilin Huang Xuelin Tian | 2023 | Nano Research2023，16，1： | 0 |
