| 1 | Enhanced N-doping in mesoporous carbon for efficient electrocatalytic CO2 conversion显示文摘The capability of electrocatalytic reducti on of carbon dioxide(CO2)using nitrogen(N)-doped carb on strongly depe nds on the N-dopi ng level and their types.In this work,we developed a strategy to generate mesoporous N-doped carb on frameworks with tun able configurati ons and contents of N dopants,by using a secondary doping process via the treatment of N,N-dimethylformamide(DMF)solvent.The obtained mesoporous N-doped carbon(denoted as MNC-D)served as an efficient electrocatalyst for electroreduction of CO2 to CO.A high Faradaic efficiency of^92%and a partial current density for CO of-6.8 mA·cm^-2 were achieved at a potential of-0.58 V vs.RHE.Electrochemical analyses further revealed that the active sites within the N-doped carb on catalysts were the pyridinic N and defects gen erated by the DMF treatme nt,which enhan ced the activati on and adsorpti on CO2 molecules.Our study suggests a new approach to develop efficie nt carb on-based catalysts for potential scalable CO2 reduction reaction(CO2RR)to fuels and chemicals. | Min Kuang Anxiang Guan Zhengxiang Gu Peng Han Linping Qian Gengfeng Zheng | 2019 | Nano Research2019，12，9： | 11 |
| 2 | Is 1.28 parts per million biomarker specific for neural progenitor cells?显示文摘Nuclear magnetic resonance-visible mobile lipid,at 1.28 parts per million(ppm),is thought to be due to mobile lipid droplets formed in cells and has been considered unique for neural progenitor cells.However,this idea remains controversial.The present study examined the 1.28 ppm biomarker in other stem cells and non-stem cells,and explored the relationship between 1.28 ppm biomarker and mobile lipid droplets.1H nuclear magnetic resonance spectroscopy of EC109 cells,mesenchymal stem cells(MSCs) and adipogenic cells differentiated from MSCs was performed.Results show that 1.28 ppm biomarker was observed in human MSCs,but was absent from EC109 cells.Following adipogenic differentiation induced for 2 weeks,the 1.28 ppm biomarker climbed remarkably,with mobile lipid droplet generation,suggesting that the 1.28 ppm biomarker is not specific for neural progenitor cells because it is also observed in MSCs and adipogenic-induced differentiated cells.Moreover,it is possible to monitor MSCs differentiation following cell transplantation,using 1.28 ppm biomarker changes. | Zhifeng Xu Chongyang Shen Haiqiang Zhu Yaowen Chen Linping Wu Peng Huang YeyuXiao Zhiwei Shen Li Pang Xiuqin Guo Lian Ma Renhua Wu | 2010 | Neural Regeneration Research2010，5，15： | 2 |
