| 2 | CO_2 methanation over TiO_2–Al_2O_3 binary oxides supported Ru catalysts显示文摘TiO_2 modified Al_2O_3 binary oxide was prepared by a wet-impregnation method and used as the support for ruthenium catalyst. The catalytic performance of Ru/TiO_2–Al_2O_3catalyst in CO_2 methanation reaction was investigated. Compared with Ru/Al_2O_3 catalyst, the Ru/TiO_2–Al_2O_3catalytic system exhibited a much higher activity in CO_2 methanation reaction. The reaction rate over Ru/TiO_2–Al_2O_3 was 0.59 mol CO_2·(g Ru)1·h-1, 3.1 times higher than that on Ru/Al_2O_3[0.19 mol CO_2·(gRu)-1·h-1]. The effect of TiO_2 content and TiO_2–Al_2O_3calcination temperature on catalytic performance was addressed. The corresponding structures of each catalyst were characterized by means of H_2-TPR, XRD, and TEM. Results indicated that the averaged particle size of the Ru on TiO_2–Al_2O_3support is 2.8 nm, smaller than that on Al_2O_3 support of 4.3 nm. Therefore, we conclude that the improved activity over Ru/TiO_2–Al_2O_3catalyst is originated from the smaller particle size of ruthenium resulting from a strong interaction between Ru and the rutile-TiO_2 support, which hindered the aggregation of Ru nanoparticles. | Jinghua Xu Qingquan Lin Xiong Su Hongmin Duan Haoran Geng Yanqiang Huang | 2016 | Chinese Journal of Chemical Engineering2016，24，1： | 4 |
| 3 | Vesicular Li3V2(PO4)3/C hollow mesoporous microspheres as an efficient cathode material for lithium-ion batteries显示文摘Vesicular lithium vanadium phosphate/carbon hollow mesoporous microspheres were fabricated using a facile polyvinylpyrrolidone-assisted aerosol-spray-assisted method and subsequent heat-treatment. While changing the content of polyvinylpyrrolidone, we found that carbon content was adjustable on the surface of lithium vanadium phosphate. By optimizing the carbon content among the composites, the electrochemical performance can be enhanced significantly. The results of electrochemical performance tests suggested that the samples exhibited good cycle performance and high discharge capability in the voltages between 3.0-4.8 V. The observed excellent electrochemical performances could be attributed to the proper content of carbon coating and the vesicular hollow mesoporous microsphere structure, increasing the transmission rate of lithium ions and reducing the structural change during charging and discharging effectively. | Hongxia Sun Haoran Du Mengkang Yu Kuangfu Huang Nan Yu Baoyou Geng | 2019 | Nano Research2019，12，8： | 4 |

| 6 | Preparation of aluminum borate whisker reinforced aluminum phosphate wave-transparent materials显示文摘Aluminum borate whisker/aluminum phosphates composites were prepared with normal pressure sintering. It was found that the aluminum borate whisker was effective to suppress the crystallization of aluminum phosphates in the aluminum borate whisker/aluminum phosphates composites and contributed to the improvement of the mechanical properties. After sintered at 1050℃ for 1 h, the flexural strength of the composites with 30 vol% aluminum borate whisker addition reached 215.3 MPa. The dielectric constant and loss tangent of the composites were 4.23 and 0.0024 at 10 GHz. | LU ZhenYu GENG HaoRan ZHANG MingXi HOU XianQin | 2008 | Chinese Science Bulletin2008，53，19： | 3 |
| 7 | LanePost:Lane-Based Optimal Routing Protocol for Delay-Tolerant Maritime Networks显示文摘Ship.to.ship, ship.to.shore radio links empowered by Wi Fi, Wi MAX etc have been recently exploited to build maritime multi.hop mesh networks to provide internet services to on.ship users. However, because of the mobility of the vessels/ships and the large inter.ship distances, nodes in the maritime network are frequently disconnected, forcing data communication in the maritime mesh networks to be opportunistic and delay.tolerant. In this paper, we present Lane Post, an optimization approach for maritime delay.tolerant routing protocol. We exploit the shipping lane information to predict the rendezvous opportunities of the ships to optimize the route selection in delay.tolerant routing. In particular, we show that when the shipping lane information is available, an opportunistic routing graph(ORG) for each ship can be constructed to predict its multi.hop data routing opportunities to the other ships or to the shore. Based on the ORG, we develop an optimal route protocol(i.e., Lane Post) for each ship to minimize its delay of multi.hop packet delivery via dynamic programming. We discussed the ways of collecting shipping lane information by centralized method or distributed method.The proposed Lane Post protocol was evaluated by ONE, an open.source delay.tolerant network simulator, which shows its dramatic performance improvement in terms of delay reduction compared to the state.of.the.art opportunistic routing protocols. | Xiongfei Geng Yongcai Wang Haoran Feng Lu Zhang | 2017 | China Communications2017，14，2： | 3 |
| 8 | Temperature dependence of densities of Sb and Bi melts显示文摘The densities of Sb and Bi melts were investigated by an improved Archimedean method. The results show that the density of the Sb melt decreases linearly with increasing temperature,but the density of the Bi melt firstly increases and then decreases as the temperature increases. There is a maximum density value of 10.002 g/cm3 at 310 ℃ ,about 39℃ above the melting point. The temperature depend-ence of the Sb melt is well fitted with the expression ρ =6.8590-5.8105×10-4T,and that of the Bi melt is fitted with ρ =10.3312-1.18×10-3T. The results were discussed from a microstructure viewpoint. | GENG HaoRan SUN ChunJing WANG Rui QI XiaoGang ZHANG Ning | 2007 | Chinese Science Bulletin2007，52，15： | 2 |
| 9 | Fabrication and abrasive wear properties of metal matrix composites reinforced with three-dimensional network structure显示文摘Reticulated polyurethane was chosen as the preceramic material for preparing the porous preform using the rep- lication process. The immersing and sintering processes were each performed twice for fabricating a high-porosity and su- per-strong skeleton. The aluminum magnesium matrix composites reinforced with three-dimensional network structure were prepared using the infiltration technique by pressure assisting and vacuum driving. Light interfacial reactions have played a profitable role in most of the ceramic-metal systems. The metal matrix composites interpenetrated with the ceramic phase have a higher wear resistance than the metal matrix phase. The volume fraction of ceramic reinforcement has a sig- nificant effect on the abrasive wear, and the wear rate can be decreased with the increase of the volume fraction of rein- forcement. | WANG Shouren GENG Haoran LI Kunshan SONG Bo WANG Yingzi HUI Linhai | 2006 | Rare Metals2006，25，6： | 2 |

| 18 | An Effective Platform for Exploring Rotavirus Receptors by Bacterial Surface Display System显示文摘Rotavirus(RV) is a major foodborne pathogen. For RV prevention and control, it is a key to uncover the interaction mechanism between virus and its receptors. However, it is hard to specially purify the viral receptors, including histo-blood group antigens(HBGAs). Previously, the protruding domain protein(P protein) of human norovirus(genotype Ⅱ.4) was displayed on the surface of Escherichia coli, and it specifically recognized and captured the viral ligands. In order to further verify the feasibility of the system, P protein was replaced by VP8* of RV(G9 P[8]) in this study. In the system, VP8*could be correctly released by thrombin treatment with antigenicity retaining, which was confirmed by Western blot and Enzyme-Linked Immunosorbent Assays. Type A HBGAs from porcine gastric mucin(PGM) were recognized and captured by this system. From saliva mixture, the captured viral receptor bound with displayed VP8* was confirmed positive with monoclonal antibody against type A HBGAs. It indicated that the target ligands could be easily separated from the complex matrix. These results demonstrate that the bacterial surface display system will be an effective platform to explore viral receptors/ligands from cell lines or food matrix. | Danlei Liu Haoran Geng Zilei Zhang Yifan Xing Danlu Yang Zhicheng Liu Dapeng Wang | 2020 | Virologica Sinica2020，35，1： | 1 |
