| 1 | Co-pyrolysis characteristics of typical components of waste plastics in a falling film pyrolysis reactor显示文摘Waste plastics mainly come from MSW and usually exist in the form of mixed plastics. During the co-pyrolysis process of mixed plastics, various plastic components have different physicochemical properties and reaction mechanisms. Considering the high viscosity and low thermal conductivity of molten plastics, a falling film pyrolysis reactor was selected to explore the rapid co-pyrolysis process of typical plastic components(PP, PE and PS).The oil and gas yields and the compositions of pyrolysis products of the three components under different ratios at pyrolysis temperatures were analyzed to explore the co-pyrolysis characteristics of PP, PE, and PS. The study is of great significance to the recycling of waste plastics. | Zechen Jin Lijie Yin Dezhen Chen Yuanjie Jia Jun Yuan Yuyan Hu | 2018 | Chinese Journal of Chemical Engineering2018，26，10： | 5 |
| 2 | Ago2 facilitates Rad51 recruitment and DNA double-strand break repair by homologous recombination显示文摘DNA 双海滨裂缝(DSB ) 是高度细胞毒素的损害并且如果,形成主要威胁到染色体稳定性不适当地修理了。我们和其它以前证明了导致 DSB 的小 RNA (diRNAs ) 的一个班在 DSB 地点附近从序列被生产。DiRNAs 与 Argonaute 被联系(以前) 蛋白质和戏在 DSB 修理的一个重要角色,不过,他们通过行动的机制仍然保持不清楚。这里,我们报导在 DSB 修理的 diRNAs 的角色被限制由相应再结合(HR ) 修理并且它明确地在哺乳动物的房间依靠受动器蛋白质 Ago2。有趣地,我们证明 Ago2 与 Rad51 形成建筑群并且相互作用在与电离对待的房间被提高放射。我们证明在 DSB 地点和 HR 修理的 Rad51 累积取决于催化活动和 Ago2 的小 RNA 有约束力的能力。相反,象装载的 RPA 和 Mre11 一样的 DSB 切除术由 Ago2 或 Dicer 弄空是未受影响的,建议 Ago2 很多半在调停直接工作在 DSB 的 Rad51 累积。一起拿,我们的调查结果建议由 diRNAs 指导了那, Ago2 能在 DSB 支持 Rad51 招募或保留由 HR 便于修理。 | Min Gao Wei Wei Ming-Ming Li Yong-Sheng Wu Zhaoqing Ba Kang-Xuan Jin Miao-Miao Li You-Qi Liao Samir Adhikari Zechen Chong Ting Zhang Cai-Xia Guo Tie-shah Tang Bing-Tao Zhu Xing-Zhi Xu Niels Mailand Yun-Gui Yang Yijun Qi Jannie M Rendtlew Danielsen | 2014 | Cell Research2014，24，5： | 3 |
| 3 | Synthesis of 1,8-naphthalimide-based fluorescent nano-probes and their application in pH detection显示文摘Two kinds of fluorescent nano-probes(pH-A and pH-B) with different diameters for the determination of H+concentration, based on photo-induced electron transfer mechanism, were synthesized through click reaction. In which 1,8-naphthalimide was employed as the fluorophore and N,N-dimethylethylenediamine as the receptor. The effects of particle size and linker length on the photophysical properties of the probe were studied. The results revealed that the nano-probes were more sensitive toward pH with increasing particle size. The fluorescence intensity at 529 nm(I529) of the nano-probe p H-A of 120 nm exhibited good linear relationship with solution's pH in the range of 6–8. The probe p H-A displayed excellent selectivity and competition toward proton over other possible coexisted ions, and it could be applied to detect pH in realistic samples(river water, urine). | Langping Zhou Zechen Jin Xiaoxiang Fan Yuhua Yao Zhaoyang Chen Weibing Zhang Junhong Qian | 2018 | Chinese Chemical Letters2018，29，10： | 2 |
| 4 | Molten waste plastic pyrolysis in a vertical falling film reactor and the influence of temperature on the pyrolysis products显示文摘Molten plastics are characterised with high viscosity and low thermal conductivity. Applying falling film pyrolysis reactor to deal with waste plastics can not only improve heat transfer efficiency, but also solve the flow problem.In this work, the pyrolysis process of molten polypropylene(PP) in a vertical falling film reactor is experimentally studied, and the influence of heating temperature on pyrolysis products is discussed. It has been found that with the temperature increases from 550 ℃ to 625 ℃, the yield of pyrolysis oil decreases from 74.4 wt%(± 2.2 wt%) to53.5 wt%(±1.3 wt%). The major compositions of the pyrolysis oil are C_9, C_(12) and C_(18), and β-scission reactions are predominant. The content of the light fraction C_6-C_(12) of pyrolysis oil is 69.7 wt%. Compared with other pyrolysis reactors, the yield of oil from vertical falling film pyrolysis reactor is slightly higher than that from tubular reactor,equal to that from rotary kiln reactor, and slightly lower than that in medium fluidised-bed reactor. | zechen jin dezhen chen lijie yin yuyan hu huangqing zhu liu hong | 2018 | Chinese Journal of Chemical Engineering2018，26，2： | 1 |
| 5 | Heat transfer characteristics of molten plastics in a vertical falling film reactor显示文摘The heat transfer efficiency during the pyrolysis process is a key factor to be considered in the design of pyrolysis reactors. In this study, the average apparent heat transfer characteristics of molten plastic pyrolysis in a vertical falling film reactor were explored by experiments and numerical simulation and the apparent heat transfer coefficients were determined. In addition, the temperature distribution and the thickness of the liquid film in the reactor were predicted and the influences of pyrolysis temperatures on the average apparent heat transfer coefficients were discussed. | Zechen Jin Lijie Yin Dezhen Chen Yuanjie Jia Jun Yuan Boyang Yu | 2019 | Chinese Journal of Chemical Engineering2019，27，5： | 0 |
