| 1 | Enhanced removal of ethylbenzene from gas streams in biotrickling filters by Tween-20 and Zn(Ⅱ)显示文摘The effects of Tween-20 and Zn(II)on ethylbenzene removal were evaluated using two biotrickling filters(BTFs),BTF1 and BTF2.Only BTF1 was fed with Tween-20 and Zn(II).Results show that ethylbenzene removal decreased from 94%to 69%for BTF1 and from 74%to 54%for BTF2 with increased organic loading from 64.8 to 189.0 g ethylbenzene/(m3·hr)at EBRT of 40 sec.The effect of EBRT(60–15 sec)at a constant ethylbenzene inlet concentration was more significant than that of EBRT(30–10 sec)at a constant organic loading.Biomass accumulation rate within packing media was reduced significantly. | Lu Wang Chunping Yang Yan Cheng Jian Huang Haining Yang Guangming Zeng Li Lu Shanying He | 2014 | Journal of Environmental Sciences2014，26，12： | 8 |
| 2 | Key technologies and engineering practices for soft-rock protective seam mining显示文摘Severe gas disasters in deep mining areas are increasing,and traditional protective coal seam mining is facing significant challenges.This paper proposes an innovative technology using soft rock as the protective seam in the absence of an appropriate coal seam.Based on the geological engineering conditions of the new horizontal first mining area of Luling Coal Mine in Huaibei,China,the impacts of different mining parameters of the soft-rock protective seam on the pressure-relief effect of the protected coal seam were analyzed through numerical simulation.The unit stress of the protected coal seam,which was less than half of the primary rock stress,was used as the mining stress pressure-relief index.The optimized interlayer space was found to be 59 m for the first soft-rock working face,with a 2 m mining thickness and 105 m face length.The physicochemical characteristics of the orebody were analyzed,and a device selection framework for the soft-rock protective seam was developed.Optimal equipment for the working face was selected,including the fully-mechanized hydraulic support and coal cutter.A production technology that combined fully-mechanized and blasting-assisted soft-rock mining was developed.Engineering practices demonstrated that normal circulation operation can be achieved on the working face of the soft-rock protective seam,with an average advancement rate of 1.64 m/d.The maximum residual gas pressure and content,which were measured at the cut hole position of the protected coal seams(Nos.8 and 9),decreased to 0.35 MPa and 4.87 m^3/t,respectively.The results suggested that soft-rock protective seam mining can produce a significant gas-control effect. | Xiang Cheng Guangming Zhao Yingming Li Xiangrui Meng Qingyi Tu | 2020 | International Journal of Mining Science and Technology2020，30，6： | 7 |
| 3 | Spin-orbit hybrid entanglement quantum key distribution scheme显示文摘We propose a novel quantum key distribution scheme by using the SAM-OAM hybrid entangled state as the physical resource.To obtain this state,the polarization entangled photon pairs are created by the spontaneous parametric down conversion process,and then,the q-plate acts as a SAM-to-OAM transverter to transform the polarization entangled pairs into the hybrid entangled pattern,which opens the possibility to exploit the features of the higher-dimensional space of OAM state to encode information.In the manipulation and encoding process,Alice performs the SAM measurement by modulating the polarization stateπ lθx on one photon,whereas Bob modulates the OAM sector state lx' on the other photon to encode his key elements using the designed holograms which is implemented by the computer-controlled SLM.With coincidence measurement,Alice could extract the key information.It is showed that N-based keys can be encoded with each pair of entangled photon,and this scheme is robust against Eve’s individual attack.Also,the MUBs are not used.Alice and Bob do not need the classical communication for the key recovery. | ZHANG ChengXian GUO BangHong CHENG GuangMing GUO JianJun FAN RongHua | 2014 | Science China(Physics,Mechanics & Astronomy)2014，57，11： | 4 |
| 4 | Osteogenic and antibacterial dual functions of a novel levofloxacin loaded mesoporous silica microspheres/nano-hydroxyapatite/ polyurethane composite scaffold显示文摘Lev/MSNs/n-HA/PU has been proved to be a novel scaffold material to treat bone defect caused by chronic osteomyelitis.We have previously identified that this material can effectively treat chronic osteomyelitis caused by Staphylococcus aureus in vivo.However,the potential mechanisms of antibacterial and osteogenic induction properties remain unclear.Thus,for osteogenesis property,immunohistochemistry,PCR,and Western blot were performed to detect the expression of osteogenic markers.Furthermore,flow cytometry and TUNEL were applied to analyze MC3T3-E1 proliferation and apoptosis.For antibacterial property,the material was co-cultivated with bacteria,bacterial colony forming units was counted and the release time of the effective levofloxacin was assayed by agar disc-diffusion test.Moreover,scanning electron microscope was applied to observe adhesion of bacteria.In terms of osteogenic induction,we found BMSCs adherently grew more prominently on Lev/MSNs/n-HA/PU.Lev/MSNs/n-HA/PU also enhanced the expression of osteogenic markers including OCN and COL1a1,as well as effectively promoted the transition from G1 phase to G2 phase.Furthermore,Lev/MSNs/n-HA/PU could reduce apoptosis of MC3T3-E1.Besides,both Lev/MSNs/n-HA/PU and n-HA/PU materials could inhibit bacterial colonies,while Lev/MSNs/n-HA/PU possessed a stronger antibacterial activities,and lower bacterial adhesion than n-HA/PU.These results illustrated that Lev/MSNs/n-HA/PU composite scaffold possess favorable compatibility in vitro,which induce osteogenic differentiation of MSCs,promote proliferation and differentiation of MC3T3-E1,and inhibit apoptosis.Moreover,clear in vitro antibacterial effect of Lev/MSNs/n-HA/PU was also observed.In summary,this study replenishes the potential of Lev/MSNs/n-HA/PU composite scaffold possess dual functions of anti-infection and enhanced osteogenesis for future clinical application. | Zhiping Kuang Guangming Dai Ruijie Wan Dongli Zhang Chen Zhao Cheng Chen Jidong Li Hongchen Gu Wei Huang | 2021 | Genes & Diseases2021，8，2： | 4 |
| 5 | Preparation and electrochemical property of CMC/MWCNT composite using ionic liquid as solvent显示文摘Carboxymethyl cellulose sodium(CMC)/multi-walled carbon nanotube(MWCNT) composite was prepared by dissolving CMC with ionic liquid as solvent.The microstructure and electrochemical properties of CMC/MWCNTs were studied using field emission scanning electron microscopy(FE-SEM),high-resolution transmission electron microscopy(HR-TEM),X-ray diffraction(XRD) system and electrochemical workstation.The experimental results indicated that the CMC dissolved with ionic liquid could be uniformly enwrapped on the surface of MWCNTs,and the coating thickness of CMC was about 5.4 nm.There are obvious oxidation peaks in the cyclic voltammograms curves of glassy carbon electrode coated with a CMC/MWCNT composite in H2O2 phosphate buffer solution.The MWCNT content and ultrasonic time strongly affected the dispersivity and electrochemical property of CMC/MWCNT composite.While the MWCNT content and ultrasonic processing time was 2 wt% and 2 h respectively,CMC/MWCNT composite exhibited excellent electrocatalytic activity. | ZHAO TingKai LIU LeHao LI GuangMing DU Li ZHAO Xing YAN Jin CHENG YouLiang DANG ALei LI TieHu | 2012 | Chinese Science Bulletin2012，57，14： | 3 |

By experimental tests,influences of flowrate inside the cooling system and fan on chip cooling are explicated. This water-cooling radiator is proved more efficient than current air-cooling radiator with comparison experiments. During cooling the heater which simulates the working of computer chip with different power,the water-cooling radiator needs shorter time to reach lower steady temperatures than current air-cooling radiator. | ZENG Ping CHENG Guangming LIU Jiulong YANG Zhigang SUN Xiaofeng PENG Taijiang | 2007 | Chinese Journal of Mechanical Engineering2007，20，2： | 3 |
| 7 | Influences of anion concentration and valence on dispersion and aggregation of titanium dioxide nanoparticles in aqueous solutions显示文摘Dispersion and aggregation of nanoparticles in aqueous solutions are important factors for safe application of nanoparticles. In this study, dispersion and aggregation of nano-TiO_2 in aqueous solutions containing various anions were investigated. The influences of anion concentration and valence on the aggregation size, zeta potential and aggregation kinetics were individually investigated. Results showed that the zeta potential decreased from 19.8 to-41.4 mV when PO_4^(3-) concentration was increased from 0 to 50 mg/L, while the corresponding average size of nano-TiO_2 particles decreased from 613.2 to 540.3 nm. Both SO_4^(2-) and NO_3^-enhanced aggregation of nano-TiO_2in solution. As SO_4^(2-) concentration was increased from 0 to 500 mg/L, the zeta potential decreased from 19.8 to 1.4 mV, and aggregate sizes increased from 613.2 to 961.3 nm.The trend for NO_3^- fluctuation was similar to that for SO_4^(2-) although the range of variation for NO_3^- was relatively narrow. SO_4^(2-) and NO_3^-accelerated the aggregation rapidly, while PO_4^(3-) did so slowly. These findings facilitate the understanding of aggregation and dispersion mechanisms of nano-TiO_2 in aqueous solutions in the presence of anions of interest. | Huijun He | 2017 | Journal of Environmental Sciences2017，29，4： | 2 |

| 10 | Enhancement of ultrasonic disintegration of sewage sludge by aeration显示文摘Sonication is an effective way for sludge disintegration,which can significantly improve the efficiency of anaerobic digestion to reduce and recycle use of sludge.But high energy consumption limits the wide application of sonication.In order to improve ultrasonic sludge disintegration efficiency and reduce energy consumption,aeration was introduced.Results showed that sludge disintegration efficiency was improved significantly by combining aeration with ultrasound.The aeration flow rate,gas bubble size,ultrasonic density and aeration timing had impacts on sludge disintegration efficiency.Aeration that used in later stage of ultrasonic irradiation with low aeration flow rate,small gas bubbles significantly improved ultrasonic disintegration sludge efficiency.At the optimal conditions of 0.4 W/m L ultrasonic irradiation density,30 m L/min of aeration flow rate,5 min of aeration in later stage and small gas bubbles,ultrasonic sludge disintegration efficiency was increased by 45% and one third of ultrasonic energy was saved.This approach will greatly benefit the application of ultrasonic sludge disintegration and strongly promote the treatment and recycle of wastewater sludge. | He Zhao Panyue Zhang Guangming Zhang Rong Cheng | 2016 | Journal of Environmental Sciences2016，28，4： | 1 |

| 15 | TRAVELING MACHINE DRIVEN BY PIEZOELECTRIC BIMORPH显示文摘A rectangular bimorph will vibrate in bending mode under alternating current (AC) electric field. If two opposite tips along longitudinal direction are both clamped,the maximum magnitude of bending displacement occurs on the short center line. Using bimorph type vibrators forementioned as actuators,an invention of simple traveling machine based on stick-slip principle is presented. The machine can not only move along both x and y direction within horizontal working plane,further-more,excellent bearing ability and agile response as well as stable step are also proved. In addition,the machine can work on stepping mode and scanning mode at the same time,hence the contradiction between long stroke and high precise positioning is solved. Therefore,it meets the needs of mi-cro/nanometer precise positioning under long stroke and is desired to be used as carrying stage for micro-assembling system and locomotive mechanism for miniature robot system. | HUA Shunming CHENG Guangming FAN Zunqiang YANG Zhigang SUZUKI Katsiyoshi | 2007 | Chinese Journal of Mechanical Engineering2007，20，2： | 1 |
