| 1 | Simultaneous mineralization of CO_2 and recovery of soluble potassium using earth-abundant potassium feldspar显示文摘CO2 capture and storage(CCS) is an important strategy in combatting anthropogenic climate change.However,commercial application of the CCS technique is currently hampered by its high energy expenditure and costs.To overcome this issue,CO2 capture and utilization(CCU) is a promising CO2 disposal method.We,for the first time,developed a promising method to mineralize CO2 using earth-abundant potassium feldspar in order to effectively reduce CO2 emissions.Our experiments demonstrate that,after adding calcium chloride hexahydrate as an additive,the K-feldspar can be transformed to Ca-silicates at 800 C,which can easily mineralize CO2 to form stable calcium carbonate and recover soluble potassium.The conversion of this process reached 84.7%.With further study,the pretreatment temperature can be reduced to 250 C using hydrothermal method by adding the solution of triethanolamine(TEA).The highest conversion can be reached 40.1%.The process of simultaneous mineralization of CO2 and recovery of soluble potassium can be easily implemented in practice and may provide an economically feasible way to tackle global anthropogenic climate change. | XIE HePing WANG YuFei JU Yang LIANG Bin ZHU JiaHua ZHANG Ru XIE LingZhi LIU Tao ZHOU XiangGe ZENG HongMei LI Chun LU HouFang | 2013 | Chinese Science Bulletin2013，58，1： | 16 |

| 3 | CFD simulation of internal-loop airlift reactor using EMMS drag model显示文摘The simulation of internal-loop airlift reactors is challenging because complex meso-scale structures exist in different sections of the reactor,separated by the draft tube.This paper reports on the computational fluid dynamics(CFD) simulation of internal-loop airlift reactors using a new drag model derived from the dual-bubble-size(DBS) model,an extended energy-minimization multi-scale(EMMS) approach for gas-liquid flows.Compared with the traditional Schiller-Naumann(S-N) correlation,the new model improves the simulation of gas holdup in the riser and downcomer significantly.In particular,gas holdup and circulation of two-phase flow can be modeled successfully using the new model,whereas traditional drag models such as the S-N correlation show an absence of gas in the downcomer.The simulation demonstrates the advantage and potential of this new model for internal-loop airlift reactors. | Tingting Xu Xuedong Jiang Ning Yang Jiahua Zhu | 2015 | Particuology2015，13，2： | 10 |
| 4 | Immobilization of functional nano-objects in living engineered bacterial biofilms for catalytic applications显示文摘Nanoscale objects feature very large surface-area-to-volume ratios and are now understood as powerful tools for catalysis,but their nature as nanomaterials brings challenges including toxicity and nanomaterial pollution.Immobilization is considered a feasible strategy for addressing these limitations.Here,as a proof-of-concept for the immobilization of nanoscale catalysts in the extracellular matrix of bacterial biofilms,we genetically engineered amyloid monomers of the Escherichia coli curli nanofiber system that are secreted and can self-assemble and anchor nano-objects in a spatially precise manner.We demonstrated three scalable,tunable and reusable catalysis systems:biofilm-anchored gold nanoparticles to reduce nitro aromatic compounds such as the pollutant p-nitrophenol,biofilm-anchored hybrid Cd0.9Zn0.1S quantum dots and gold nanoparticles to degrade organic dyes and biofilm-anchored CdSeS@ZnS quantum dots in a semi-artificial photosynthesis system for hydrogen production.Our work demonstrates how the ability of biofilms to grow in scalable and complex spatial arrangements can be exploited for catalytic applications and clearly illustrates the design utility of segregating high-energy nano-objects from injury-prone cellular components by engineering anchoring points in an extracellular matrix. | Xinyu Wang Jiahua Pu Yi Liu Fang Ba Mengkui Cui Ke Li Yu Xie Yan Nie Qixi Mi Tao Li Lingli Liu Manzhou Zhu Chao Zhong | 2019 | National Science Review2019，6，5： | 9 |
| 5 | Onset velocity of circulating fluidization and particle residence time distribution:A CFD-DEM study显示文摘Until now,the onset velocity of circulating fluidization in liquid-solid fluidized beds has been defined by the turning point of the time required to empty a bed of particles as a function of the superficial liquid velocity,and is reported to be only dependent on the liquid and particle properties.This study presents a new approach to calculate the onset velocity using CFD-DEM simulation of the particle residence time distribution(RTD).The onset velocity is identified from the intersection of the fitted lines of the particle mean residence time as a function of superficial liquid velocity.Our results are in reasonable agreement with experimental data.The simulation indicates that the onset velocity is influenced by the density and size of particles and weakly affected by riser height and diameter.A power-law function is proposed to correlate the mean particle residence time with the superficial liquid velocity.The collisional parameters have a minor effect on the mean residence time of particles and the onset velocity,but influence the particle RTD,showing some humps and trailing.The particle RTD is found to be related to the particle trajectories,which may indicate the complex flow structure and underlying mechanisms of the particle RTD. | Qiqi Han Ning Yang Jiahua Zhu Mingyan Liu | 2015 | Particuology2015，13，4： | 8 |
| 6 | Distribution of isotopes and chemicals in precipitation in Shule River Basin,northwestern China:an implication for water cycle and groundwater recharge显示文摘The distribution of stable isotopes and ions in precipitation in the Shule River Basin,northwestern China,were investigated to understand the regional water cycle and precipitation input to groundwater recharge.The study found that the mean annual concentrations of Ca2+,Na+,SO42–,Cl–,Mg2+,NO3–,and K+ in the basin were lower than those in other arid areas of northwestern China.The average concentrations of ions in the lower reaches of the Shule River were higher than those in the upper reaches.The results showed that the main ionic concentrations decreased with the increase of precipitation amount,indicating that heavy precipitation cannot only wash crustal aerosols out of the atmosphere,but also create a dilution effect.Cl– and Na+ in precipitation had a strong and positive correlation,suggesting a common origin for the two ions.However,the excess of Na+,combined with non-marine SO42– and NO3–,indicated that some ions were contributed by terrestrial origins.In the extremely arid regions of northwestern China,the evaporation process obviously changes the original relationship between δ2H and δ18O in precipitation,and leads to dexcess values <8‰.δ18O and temperature were significantly correlated,suggested that temperature strongly affected the characteristics of isotopes in the study area.The δ18O value indicates a dominant effect of westerly air masses and southwest monsoon in warm months,and the integrated influence of westerly and Siberian-Mongolian polar air masses in cold months.The d-excess values were generally lower in warm months than those in cold months,indicating that post-condensation processes played a significant role in the water cycle.The results provide reliable precipitation input information that can be used in future groundwater recharge calculations in the study area. | ZHAO Wei MA Jinzhu GU Chunjie QI Shi ZHU Gaofeng HE Jiahua | 2016 | Journal of Arid Land2016，8，6： | 6 |
| 7 | Retrospective analysis of interventional treatment of hepatic metastasis from gastroenteropancreatic neuroendocrine tumors显示文摘Objective: To analyze the angiography appearance of liver metastases from gastroenteropancreatic neuroendocrine tumors(GEP-NETs),and evaluate the clinical efficacy and prognostic factors of interventional treatment for hepatic metastases.Methods: Fifty GEP-NETs patients with hepatic metastases were treated from January 2012 to December 2016,and received transarterial embolization(TAE) in the hepatic tumor or hepatic arterial infusion chemotherapy(HAIC).All patients received 179 times of the intervention therapy in total.Results: Blood supplies were identified in the 50 cases with angiography,which showed that 35 cases had abundant vessels,while 15 cases had poor blood supply.Twenty-two cases were found either collateral blood supply,or portal vein invasion or arterial-portal vein fistula.The best curative efficacy was complete remission(CR)in 4 cases,partial remission(PR) in 28 cases and stable disease(SD) in 18 cases during the process of treatment.The angiography(P=0.047) and the frequency of intervention(P=0.037) showed significantly statistical difference with Kaplan-Meier analysis.The Cox analysis showed that more than 3 times of interventional therapy was an independent prognostic factor.Conclusions: Interventional treatment is safe and effective for GEP-NETs,and is beneficial to patients with main hepatic metastases after endocrine therapy. | Peng Liu Xu Zhu Jie Li Ming Lu Jiahua Leng Ying Li Jiangyuan Yu | 2017 | Chinese Journal of Cancer Research2017，29，6： | 4 |
| 8 | Rationale for the use of multifunctional drugs as neuroprotective agents for glaucoma显示文摘Glaucoma, the leading cause globally of irreversible blindness, is a neurodegenerative disease characterized by progressive retinal ganglion cell death. To date, no drug has been shown to prevent the retinal ganglion cell loss associated with glaucoma. Multiple mechanisms lead to ganglion cell death in glaucoma, suggesting that a neuroprotectant that has a single mode of action, like memantine, would have a limited positive effect at slowing down ganglion cell death. Conversely, simultaneously targeting several factors may be the best therapeutic approach to improve outcomes. Multifunctional drugs are fast gaining acceptance as a strategy for the treatment of complex disor-ders of the central nervous system, such as Parkinson's disease, Alzheimer's disease and other progressive neurodegenerative diseases. In this paper, we review the current literature on multi-functional drugs and propose a rationale for the use of multifunctional drugs in glaucomatous optic neuropathy. | Jiahua Fang Fagang Jiang Jingbo Li Yanhua Zhu | 2012 | Neural Regeneration Research2012，7，4： | 3 |
| 9 | Estimating Fraction of Photosynthetically Active Radiation of Corn with Vegetation Indices and Neural Network from Hyperspectral Data显示文摘The fraction of photosynthetically active radiation(FPAR) is a key variable in the assessment of vegetation productivity and land ecosystem carbon cycles.Based on ground-measured corn hyperspectral reflectance and FPAR data over Northeast China,the correlations between corn-canopy FPAR and hyperspectral reflectance were analyzed,and the FPAR estimation performances using vegetation index(VI) and neural network(NN) methods with different two-band-combination hyperspectral reflectance were investigated.The results indicated that the corncanopy FPAR retained almost a constant value in an entire day.The negative correlations between FPAR and visible and shortwave infrared reflectance(SWIR) bands are stronger than the positive correlations between FPAR and near-infrared band reflectance(NIR).For the six VIs,the normalized difference vegetation index(NDVI) and simple ratio(SR) performed best for estimating corn FPAR(the maximum R2 of 0.8849 and 0.8852,respectively).However,the NN method esti-mated results(the maximum R2 is 0.9417) were obviously better than all of the VIs.For NN method,the two-band combinations showing the best corn FPAR estimation performances were from the NIR and visible bands;for VIs,however,they were from the SWIR and NIR bands.As for both the methods,the SWIR band performed exceptionally well for corn FPAR estimation.This may be attributable to the fact that the reflectance of the SWIR band were strongly controlled by leaf water content,which is a key component of corn photosynthesis and greatly affects the absorption of photosynthetically active radiation(APAR),and makes further impact on corn-canopy FPAR. | YANG Fei ZHU Yunqiang ZHANG Jiahua YAO Zuofang | 2012 | Chinese Geographical Science2012，22，1： | 2 |
| 10 | An Efficient Priority-Driven Congestion Control Algorithm for Data Center Networks显示文摘With the emerging diverse applications in data centers,the demands on quality of service in data centers also become diverse,such as high throughput of elephant flows and low latency of deadline-sensitive flows.However,traditional TCPs are ill-suited to such situations and always result in the inefficiency(e.g.missing the flow deadline,inevitable throughput collapse)of data transfers.This further degrades the user-perceived quality of service(QoS)in data centers.To reduce the flow completion time of mice and deadline-sensitive flows along with promoting the throughput of elephant flows,an efficient and deadline-aware priority-driven congestion control(PCC)protocol,which grants mice and deadline-sensitive flows the highest priority,is proposed in this paper.Specifically,PCC computes the priority of different flows according to the size of transmitted data,the remaining data volume,and the flows’deadline.Then PCC adjusts the congestion window according to the flow priority and the degree of network congestion.Furthermore,switches in data centers control the input/output of packets based on the flow priority and the queue length.Different from existing TCPs,to speed up the data transfers of mice and deadline-sensitive flows,PCC provides an effective method to compute and encode the flow priority explicitly.According to the flow priority,switches can manage packets efficiently and ensure the data transfers of high priority flows through a weighted priority scheduling with minor modification.The experimental results prove that PCC can improve the data transfer performance of mice and deadline-sensitive flows while guaranting the throughput of elephant flows. | Jiahua Zhu Xianliang Jiang Yan Yu Guang Jin Haiming Chen Xiaohui Li Long Qu | 2020 | China Communications2020，17，6： | 2 |

| 13 | Effect of the protrusion shape on gas ingestion of two sealing structures显示文摘The windage loss caused by protrusion in a rotor–stator cavity has been studied in detail,and there are abundant fitting formulas that have been summarized to calculate the moment coefficients.Some other theorists have emphasized its effect on the sealing efficiency,proposing that installation of protrusion could alleviate gas ingestion.However,the protrusion shape which is an influential factor on the sealing efficiency has not been focused in previous research.Using the experimental method of measuring CO2 volume fraction,cavity pressure,and power consumption,we investigated the effects of several typical protrusion shapes on various parameters for two sealing structures,in order to obtain the optimal shape.Results showed that a variation of the protrusion shape had little impact on the static pressure,but the total pressure and the sealing efficiency increased in different degrees.Furthermore,even though the hexagon shape resulted in the highest sealing efficiency,we observed that the drop shape had the best overall performance in all of the eight models,which could result in higher efficiency of the turbine cavity.The combination of a radial seal structure and protrusion could improve sealing efficiency better. | Zeyu WU Xiang LUO Jianqin ZHU Hang CHEN Jiahua LIU | 2021 | Chinese Journal of Aeronautics2021，34，4： | 1 |
