| 1 | Covalent organic frameworks derived hollow structured N-doped noble carbon for asymmetric-electrolyte Zn-air battery显示文摘We report a relatively low-temperature molten salt strategy to prepare hollow structured N-doped noble carbon(h-NNC) with highly desirable features of ultra-large surface area(1957 m^2 g^(-1)) and high graphitization, endowing the h-NNC with high activity toward catalysis of oxygen reduction reaction in acidic medium. The h-NNC is applied as cathode catalyst of an asymmetrical-electrolyte Zn-air battery, which exhibits an open circuit voltage of 2.11 V, a power density up to 270 mW cm^(-2),and an energy density of 1279 W h kg^(-1), behaving advantages over the conventional Zn-air batteries. | Pingwei Cai Xinxin Peng Junheng Huang Jingchun Jia Xiang Hu Zhenhai Wen | 2019 | Science China Chemistry2019，62，3： | 6 |
| 2 | Polycrystalline diamond MESFETs by Au-mask technology for RF applications显示文摘Metal-semiconductor field effect transistors (MESFETs) were fabricated on H-terminated polycrystalline diamond.The DC characteristics of the p-channel MESFET showed a maximum drain current density of 204 mA/mm at a gate-source voltage of 6 V,and a maximum transconductance of 20 mS/mm at a gate-source voltage of 1.5 V.The small signal S-parameters of MESFET with 2 100 m gate width and 2 m gate length were measured.An extrinsic cut-off frequency (fT) of 1.7 GHz and the maximum oscillation frequency (fmax) of 2.5 GHz were obtained,which was the first report on diamond MESFETs with RF characteristics in China. | FENG ZhiHong WANG JingJing HE ZeZhao DUN ShaoBo YU Cui LIU JinLong ZHANG PingWei GUO Hui LI ChengMing CAI ShuJun | 2013 | Science China(Technological Sciences)2013，56，4： | 2 |
| 3 | Chemical-mechanically polishing large area free-standing CVD diamond films显示文摘Chemical mechanical polishing is used to polish large area free-standing CVD diamond films with diameters of 66 mm.The influence of polishing plates(iron plate,asphalt plate and soft cushion)and oxidizing agents(K_2S_2O_8 and K_2FeO_4)on polishing results are investigated.Profilometer(tip radius 5μm),optical microscope and Raman spectroscopy are used to evaluate the polishing effects of the CVD diamond films.Results show that the material removal rate of iron plate is the highest,while the surface polished by soft cushion is the most uniform with roughness of 2nm.It is also found that the most effective oxidizing agent is K_2FeO_4.In conclusion,the optimum polishing conditions are soft cushion and K_2FeO_4. | ZHANG Pingwei TONG Tingting CAI Yunhong | 2018 | 金刚石与磨料磨具工程2018，38，6： | 1 |
| 4 | Microparticles released by Listeria monocytogenes-infected macrophages are required for dendritic cell-elicited protective immunity显示文摘在在为 T 房间有免疫力的回答处理和细菌的抗原的表示的巨噬细胞和树枝状的房间之间的相互影响仍然保持糟糕理解。用 Listeria monocytogenes (Lm ) 感染模型,我们证明树枝状的房间(DC ) 要求巨噬细胞的支持对 Lm 感染得到保护的免疫。DC 自己在收起 Lm 是低效的但是能够收起感染 Lm 的巨噬细胞释放的 microparticles (MP ) 。这些 MP 把 Lm 抗原转移了到 DC,允许 DC 介绍 Lm 抗原给受动器 T 房间。调停 MP 的 Lm 抗原转移要求了 MHC 一级参予,自从在巨噬细胞的 MHC 一级缺乏导致了 T 房间激活的重要减小。而且,有从感染 Lm 的巨噬细胞的 MP 的老鼠的种痘对 Lm 感染生产了强壮的保护的免疫。我们这里在 Lm 感染期间识别在巨噬细胞和 DC 之间的一个内在的抗原转移节目,并且强调巨噬细胞也在得到 DC 的 Lm 特定的 T 房间回答起一个必要作用。 | Yi Zhang Ruihua Zhang Huafeng Zhang Jing Liu Zhuoshun Yang Pingwei Xu Wenqian Cai Geming Lu Miao Cui Reto A Schwendener Huang-Zhong Shi Huabao Xiong Bo Huang | 2012 | Cellular & Molecular Immunology2012，9，6： | 1 |
| 5 | Tri-profit electrolysis for energy-efficient production of benzoic acid and H_(2)显示文摘Electrosynthesis has recently attracted intensive research attentions and holds great potential in implementing scalable green synthesis thanks to more and more readily accessible renewable electric energy. | Chi Zhang Suqin Ci Xinxin Peng Junheng Huang Pingwei Cai Yichun Ding Zhenhai Wen | 2021 | Journal of Energy Chemistry2021，30，3： | 0 |
