The hierarchical porous N/O co-functionalized carbon(HPNOC)was scalably prepared by using the lowcost and renewable blighted grains as the raw material coupled with mild KHCO_3 activation for electrochemical capacitors(ECs).The elemental N was in situ doped in the obtained HPNOC without any N-containing ***,the obtained HPNOC was endowed with a large specific surface area(about 2 624m^2·g^(-1)),high pore volume(about 1.35cm^3·g^(-1)),as well as high-content N/O functionalization(about 1.9%(in atom)N and about 10.2%(in atom)***,the as-resulted HPNOC electrode with a high mass loading of 5mg·cm^(-2 )exhibited competitive gravimetric capacitances of about 373.6F·g^(-1 )at 0.5A·g^(-1),and even about 260.4F·g^(-1 )at a high rate of 10A·g^(-1);superior capacitance retention of about 98.8%at 1A·g^(-1 )over 10 000consecutive cycles;and high specific energy of about 9.6W·h·kg^(-1 )at a power of 500W·kg^(-1),when evaluated as a promising electrode in 6mol KOH for advanced electrochemical *** encouragingly,the green synthetic strategy we developed holds a huge promise in generalizing for other biomass-derived carbon materials for versatile energy-related applications.

Nano Research 2013年第4期6卷 293-301页

作者： Zhenyu Liu Guoxin Zhang zhiyi Lu Xiuyan Jin Zheng Chang Xiaoming sun State Key Laboratory of Chemical Resource Engineering P. O. Box 98 Beijing University of Chemical Technology Beijing 100029 China

N-doped porous carbon materials have been prepared by a simple one-step pyrolysis of ethylenediaminetetraacetic acid （EDTA） and melamine in the presence of KOH and Co（NO3）2·6H20. The combination of the high specific area （1,485 m2.g-l）, high nitrogen content （10.8%） and suitable graphitic degree results in catalysts exhibiting high activity （with onset and half-wave potentials of 0.88 and 0.79 V vs the reversible hydrogen electrode （RHE）, respectively） and four-electron selectivity for the oxygen reduction reaction （ORR） in alkaline medium---comparable to a commercial Pt/C catalyst, but far exceeding Pt/C in stability and durability. Owing to their superb ORR performance, low cost and facile preparation, the catalysts have great potential applications in fuel cells, metal-air batteries, and ORR-related electrochemical industries.

Aquatic plants develop strong fragment propagation and colonization ability to endure the natural disturbances. However, detailed research of ability to endure the natural disturbances has been lacking to date. Therefore, reproduction （shoot） and colonization （root） of shoot fragments of Potamogeton crispus L. with or without apices were investigated for the effect of apical dominance, and the growth of decapitated shoot fragments at three lengths （2, 4, 6 cm） was compared. Meanwhile, fragment propagation at levels of bud position was studied for bud position effect after escaping from apical dominance. The results showed significant increases occurred in the outgrowth of lateral branches on fragments decapitated compared with the fragments with apices, implying that apical dominance exists. Different lengths of fragments showed little difference in biomass allocations, but significant differences were noted in their propagation. Meanwhile, the effect of bud position was verified, due to the significant difference of average reproduction per node among the three length groups. Thus, the present study has made progress in the current understanding of aquatic plant dispersion among natural systems and contributes to improve methods of in vitro propagation for re-implantation purposes.

随着工艺演进,尺寸进一步缩小带来了更多寄生通路和更大的寄生电阻,后仿结果和前仿相去甚远。如何快速缩小前后仿之间的差距成为重要课题。传统设计中只能通过Quantus Extracted View相对直观地对寄生进行分析,无法更详细地进行分析,这成为设计者们面临的艰巨挑战。同时,后仿发现问题,只能通过“修改电路-版图迭代-再次后仿”反复优化,迭代周期长,如何降低时间成本成为各公司关注的重点。Virtuoso iQuantus insight(ViQi)/Quantus insight(Qi)可基于寄生网表文件进行寄生分析及结果可视化。工程师可借此对寄生进行准确的分析及假设,无需版图迭代,即可进行设计优化。讨论了如何通过ViQi/Qi工具在FiNFET先进工艺项目中实现快速的后仿迭代,大幅提高工作效率。
