| 1 | A robust optimization method for energy management of CCHP microgrid显示文摘Energy management is facing new challenges due to the increasing supply and demand uncertainties,which is caused by the integration of variable generation resources,inaccurate load forecasts and non-linear efficiency curves.To meet these challenges,a robust optimization method incorporating piecewise linear thermal and electrical efficiency curve is proposed to accommodate the uncertainties of cooling,thermal and electrical load,as well as photovoltaic(PV)output power.Case study results demonstrate that the robust optimization model performs better than the deterministic optimization model in terms of the expected operation cost.The fluctuation of net electrical load has greater effect on the dispatching results of the combined cooling,heating and power(CCHP)microgrid than the fluctuation of the cooling and thermal load.The day-ahead schedule is greatly affected by the uncertainty budget of the load demand.The economy of the optimal decision could be achieved by adjusting different uncertainty budget levels according to control the conservatism of the model. | Zhao LUO Wei GU Zhi WU Zhihe WANG Yiyuan TANG | 2018 | Journal of Modern Power Systems and Clean Energy2018，6，1： | 12 |
| 2 | Bone physiological microenvironment and healing mechanism:Basis for future bone-tissue engineering scaffolds显示文摘Bone-tissue defects affect millions of people worldwide.Despite being common treatment approaches,autologous and allogeneic bone grafting have not achieved the ideal therapeutic effect.This has prompted researchers to explore novel bone-regeneration methods.In recent decades,the development of bone tissue engineering(BTE)scaffolds has been leading the forefront of this field.As researchers have provided deep insights into bone physiology and the bone-healing mechanism,various biomimicking and bioinspired BTE scaffolds have been reported.Now it is necessary to review the progress of natural bone physiology and bone healing mechanism,which will provide more valuable enlightenments for researchers in this field.This work details the physiological microenvironment of the natural bone tissue,bone-healing process,and various biomolecules involved therein.Next,according to the bone physiological microenvironment and the delivery of bioactive factors based on the bone-healing mechanism,it elaborates the biomimetic design of a scaffold,highlighting the designing of BTE scaffolds according to bone biology and providing the rationale for designing next-generation BTE scaffolds that conform to natural bone healing and regeneration. | Guanyin Zhu Tianxu Zhang Miao Chen Ke Yao Xinqi Huang Bo Zhang Yazhen Li Jun Liu Yunbing Wang Zhihe Zhao | 2021 | Bioactive Materials2021，6，11： | 11 |
| 3 | Preparation and activity evaluation of NiMoB/-Al_2O_3 catalyst by liquid-phase furfural hydrogenation显示文摘Amorphous MoNiB/ -Al 2 O 3 alloy catalysts were prepared by reducing NiCl 2 ·6H 2 O and (NH 4 ) 6 Mo 7 O 24 ·4H 2 O supported on -Al 2 O 3 with NaBH 4 as reducing agent. Using liquid-phase hydro-genation of furfural (FFR) as a probe reaction, the activity of MoNiB/ -Al 2 O 3 was examined. Compared to NiB and NiMoB, NiMoB/ -Al 2 O 3 exhibited excellent activity and selectivity towards furfuryl alcohol (FFA). After reaction for 3.0 h at 80 ℃ and 5.0 MPa in methanol, FFR conversion reached 99% with FFA yield of 91%. The effects of doping amount of Mo and calcination temperature before NaBH 4 reduction on hydrogenation activity were also investigated. The optimum Mo/Ni atom ratio and calcination temperature were found to be 1:7 and 300 ℃, respectively. XRD patterns and SEM images indicated that NiMoB over the surface of -Al 2 O 3 was amorphous and highly dispersed, which was responsible for the high thermal stability of the title catalyst. | Shuqin Wei Hongyou Cui Jinghua Wang Shuping Zhuo Weiming Yi Lihong Wang Zhihe Li | 2011 | Particuology2011，9，1： | 7 |
| 4 | Fracture Characteristics and Heat Accumulation of Jixianian Carbonate Reservoirs in the Rongcheng Geothermal Field, Xiong'an New Area显示文摘Geothermal energy plays an important role in urban construction of the Xiong’an New Area. Geothermal reservoir fracture distribution of the Mesoproterozoic Jixianian Wumishan Formation(Fm.) carbonate reservoir in the Rongcheng geothermal field are evaluated based on FMI log from Wells D19 and D21. The results show carbonate reservoir fracture density of Well D19 is 15.2/100 m, greater than that of Well D21 with a value of 9.2/100 m. Reservoir porosity and permeability of Well D19 are better than that of Well D21, and the water saturation is bimodally distributed. The movable fluid volume ratio(BVM) of Well D19 is 2% to 8% with some zones exceeding 20%, while the value of Well D21 is less than 4%. Therefore, reservoir fractures in Well D19 are more conducive to fluid flow. Reservoir fractures have a similar occurrence to normal faults, indicating that the tensile stress field controlled the formation of such fractures. Developed reservoir fractures provide a good channel for groundwater convection. The circulation of regional groundwater and the heat exchange between water and rock and the multiple heat accumulation patterns form a stable and high potential heat reservoir in the Rongcheng geothermal field. | WANG Yingjin MA Feng XIE Heping WANG Guiling WANG Zhihe | 2021 | Acta Geologica Sinica(English Edition)2021，95，6： | 5 |
| 5 | In-situ/operando techniques to identify active sites for thermochemical conversion of CO_(2) over heterogeneous catalysts显示文摘The catalytic conversion of CO_(2) to fuels or chemicals is considered to be an effective pathway to mitigate the greenhouse effect. To develop new types of efficient and durable catalysts, it is critical to identify the catalytic active sites, surface intermediates, and reaction mechanisms to reveal the relationship between the active sites and catalytic performance. However, the structure of a heterogeneous catalyst usually dynamically changes during reaction, bringing a great challenge for the identification of catalytic active sites and reaction pathways. Therefore, in-situ/operando techniques have been employed to real-time monitor the dynamic evolution of the structure of active sites under actual reaction conditions to precisely build the structure–function relationship. Here, we review the recent progress in the application of various in-situ/operando techniques in identifying active sites for catalytic conversion of CO_(2) over heterogeneous catalysts. We systematically summarize the applications of various optical and X-ray spectroscopy techniques, including Raman spectroscopy, Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and X-ray absorption spectroscopy (XAS), in identifying active sites and determining reaction mechanisms of the CO_(2) thermochemical conversion with hydrogen and light alkanes over heterogeneous catalysts. Finally, we discuss challenges and opportunities for the development of in-situ characterization in the future to further enlarge the capability of these powerful techniques. | Kai Feng Yaning Wang Man Guo Jingpeng Zhang Zhengwen Li Tianyu Deng Zhihe Zhang Binhang Yan | 2021 | Journal of Energy Chemistry2021，30，11： | 5 |
| 6 | Recommending Authors and Papers Based on ACTTM Community and Bilayer Citation Network显示文摘Citation network is often used for academic recommendation. However, it is difficult to achieve high recommendation accuracy and low time complexity because it is often very large and sparse and different citations have different purposes. What's more, some citations include unreasonable information, such as in case of intentional self-citation. To improve the accuracy of citation network-based academic recommendation and reduce the time complexity, we propose an academic recommendation method for recommending authors and papers. In which, an author-paper bilayer citation network is built, then an enhanced topic model, Author Community Topic Time Model(ACTTM) is proposed to detect high quality author communities in the author layer, and a set of attributes are proposed to comprehensively depict the author/paper nodes in the bilayer citation network. Experimental results prove that the proposed ACTTM can detect high quality author communities and facilitate low time complexity, and the proposed academic recommendation method can effectively improve the recommendation accuracy. | Meilian Lu Zhihe Qu Mengxing Wang Zhen Qin | 2018 | China Communications2018，15，7： | 4 |
| 7 | Polydopamine-mediated graphene oxide and nanohydroxyapatite-incorporated conductive scaffold with an immunomodulatory ability accelerates periodontal bone regeneration in diabetes显示文摘Regenerating periodontal bone tissues in the aggravated inflammatory periodontal microenvironment under diabetic conditions is a great challenge.Here,a polydopamine-mediated graphene oxide(PGO)and hydroxyapatite nanoparticle(PHA)-incorporated conductive alginate/gelatin(AG)scaffold is developed to accelerate periodontal bone regeneration by modulating the diabetic inflammatory microenvironment.PHA confers the scaffold with osteoinductivity and PGO provides a conductive pathway for the scaffold.The conductive scaffold promotes bone regeneration by transferring endogenous electrical signals to cells and activating Ca2+channels.Moreover,the scaffold with polydopamine-mediated nanomaterials has a reactive oxygen species(ROS)-scavenging ability and anti-inflammatory activity.It also exhibits an immunomodulatory ability that suppresses M1 macrophage polarization and activates M2 macrophages to secrete osteogenesis-related cytokines by mediating glycolytic and RhoA/ROCK pathways in macrophages.The scaffold induces excellent bone regeneration in periodontal bone defects of diabetic rats because of the synergistic effects of good conductive,ROS-scavenging,anti-inflammatory,and immunomodulatory abilities.This study provides fundamental insights into the synergistical effects of conductivity,osteoinductivity,and immunomodulatory abilities on bone regeneration and offers a novel strategy to design immunomodulatory biomaterials for treatment of immune-related diseases and tissue regeneration. | Yazhen Li Lu Yang Yue Hou Zhenzhen Zhang Miao Chen Maoxia Wang Jin Liu Jun Wang Zhihe Zhao Chaoming Xie Xiong Lu | 2022 | Bioactive Materials2022，7，12： | 3 |
| 8 | Transport properties,upper critical field and anisotropy of Ba(Fe_(0.75)Ru_(0.25))_2As_2 single crystals显示文摘The temperature and angle dependent resistivity of Ba(Fe 0.75 Ru 0.25) 2 As 2 single crystals were measured in magnetic fields up to 14 T.The temperature dependent resistivity with the magnetic field aligned parallel to c-axis and ab-planes allow us to derive the slope of dH ab c2 /dT and dH c c2 /dT near T c yielding an anisotropy ratio Γ = dH ab c2 /dT/dH c c2 /dT ≈ 2.By scaling the curves of resistivity vs.angle measured at a fixed temperature but different magnetic fields within the framework of the anisotropic Ginzburg-Landau theory,we obtained the anisotropy in an alternative way.Again we found that the anisotropy(m c /m ab) 1/2 was close to 2.This value is similar to that in Ba0.6K0.4Fe2As2(K-doped Ba122) and Ba(Fe 0.92 Co 0.08) 2 As 2(Co-doped Ba122).This suggests that the 3D warping effect of the Fermi surface in Ru-doped samples may not be stronger than that in the K-doped or Co-doped Ba122 samples,therefore the possible nodes appearing in Ru-doped samples cannot be ascribed to the 3D warping effect of the Fermi surface. | XING Jie SHEN Bing ZENG Bin LIU JianZhong DING XiaXin WANG ZhiHe YANG Huan WEN HaiHu | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，12： | 2 |
| 9 | Multi-ion intercalated Ti_(3)C_(2)T_(x)MXene and the mutual modulation within interlayer显示文摘Intercalation of ions between the adjacent MXene layers can change the interlayer environment and influence the electrochemical ion storage capacity.In order to understand the effect of multi-ions confined by the MXene layers on the performance of electrochemical energy storage,Co^(2+),Mn^(2+)and Ni^(2+)intercalated into Ti_(3)C_(2)T_(x)MXene which already pre-intercalated Al3+are obtained by spontaneous static action.Based on the monitor of(002)crystal orientation,intercalated multi-ions can regulate and control the interlayer environment of MXenes via stress,which induces lattice shrinkage occurring in the c axis.Limited by ion storage mechanism-performance,the multi-ion occupies the interspace of MXene and affects the electrochemical performance.This work would offer guidance to understand the relationship among the multi-ion and MXene by two-dimensional(2D)layered materials. | Zhihe Wang Yixuan Wang Qinhua Gu Cuimei Zhao Junkai Zhang Shichong Xu Ming Lu Bingsen Zhang | 2023 | Particuology2023，，1： | 1 |

| 12 | Laboratory and pilot scale studies on fast pyrolysis of corn stover显示文摘In order to design a hot ceramic ball heated down-flow tuber reactor for the pyrolysis liquefaction of agricultural residues,the devolatilization characteristics of pulverized corn stover were studied in a Laminar Entrained Flow Furnace(LEFF)with the temperature range of 800-950 K.The flow characteristics of corn stover particles and ceramic balls in a vertical square tube were measured and analyzed by the techniques of particle image velocimetry(PIV).The devolatilization experiments were carried out in an isothermal manner and the maximum of volatile matter of pulverized corn stover particles was 72.68%with the residence time of 189 ms at 950 K.Parameters of the first order Arrhenius equation for describing the pulverized corn stover flash pyrolysis were determined.In the PIV experiments,the corn stover particle axial velocity were measured at different cross-sections of the tube for different conditions.For the tuber connected with a suction pump,the maximum velocity was about 0.79 m/s,determined by the flow rate of the suction pump.Finally,a hot ceramic ball heated down-flow tuber reactor was constructed for pilot demonstration.The capacity of the reactor was 110.5 kg/h of corn stover powder and the yield of bio-oil was 41.6%of the feed stock. | Yi Weiming Bai Xueyuan Li Zhihe Wang Lihong Wang Nana Yang Yanqiang | 2008 | International Journal of Agricultural and Biological Engineering2008，1，1： | 1 |

| 14 | Preparation of bio-oil by catalytic pyrolysis of corn stalks using red mud显示文摘Red mud is a solid waste residue with alkaline nature(pH>12)-originating from the Bayer process in the production of alumina,which was probed in catalytic pyrolysis to determine its feasibility as a solid catalyst for bio-oil formulation.The red mud was characterized using X-ray fluorescence,XRD(X-ray diffraction),TG-DTG(thermogravimetry-derivative thermogravimetry),BET(surface area and pore size analyzer)measuring and testing techniques.Experiments of non-catalytic and catalytic pyrolysis of 40-60 mesh size corn stalk powder were channelled for bio-oil production in a fixed bed reactor.It was ascertained that adding different proportions of red mud had minute influence on bio-oil production rate and product distribution.The study signaled that liquid yield from the catalytic pyrolysis was lower than that from non-catalytic pyrolysis.Through a series of bio-oil characterization,it was encountered that the most obviously change in the bio-oil from catalytic pyrolysis was significant acidity reduction(pH>4).Meanwhile,the content of ketones and phenols was enhanced.Hence,the co-processing of agricultural waste and by-products alumina industry may offer an economical and environmentally friendly way of catalytic pyrolysis with abbreviating the red mud environmental effects. | Wang Shaoqing Xu Meili Wang Fang Li Zhihe | 2016 | International Journal of Agricultural and Biological Engineering2016，9，5： | 1 |
| 15 | Development of a Bird-like Flapping-wing Aerial Vehicle with Autonomous Take-off and Landing Capabilities显示文摘The lack of autonomous take-off and landing capabilities of bird-like flapping-wing aerial vehicles(BFAVs)seriously restricts their further development and application.Thus,combined with the current research results on the autonomous take-off and landing technology of unmanned aerial vehicles,four types of technologies are studied,including jumping take-off and landing technology,taxiing take-off and landing technology,gliding take-off and landing technology,and vertical take-off and landing(VTOL)technology.Based on the analytic hierarchy process(AHP)-comprehensive evaluation method,a fuzzy comprehensive evaluation model for the autonomous take-off and landing scheme of a BFAV is established,and four schemes are evaluated concretely.The results show that under the existing technical conditions,the hybrid layout VTOL scheme is the best.Furthermore,the detailed design and development of the prototype of a BFAV with a four-rotor hybrid layout are carried out,and the vehicle performance is tested.The results prove that through the four-rotor hybrid layout design,the BFAV has good autonomous take-off and landing abilities.The power consumption analysis shows that for a fixed-point reconnaissance mission,when the mission radius is less than 3.38 km,the VTOL type exhibits longer mission duration than the hand-launched type. | Dongfu Ma Bifeng Song Zhihe Wang Jianlin Xuan Dong Xue | 2021 | Journal of Bionic Engineering2021，18，6： | 1 |

| 18 | In-depth investigation of the exothermic reactions between lithiated graphite and electrolyte in lithium-ion battery显示文摘Thermal runaway is a critical issue for the large application of lithium-ion batteries.Exothermic reactions between lithiated graphite and electrolyte play a crucial role in the thermal runaway of lithium-ion batteries.However,the role of each component in the electrolyte during the exothermic reactions with lithiated graphite has not been fully understood.In this paper,the exothermic reactions between lithiated graphite and electrolyte of lithium-ion battery are investigated through differential scanning calorimetry(DSC) and evolved gas analysis.The lithiated graphite in the presence of electrolyte exhibit three exothermic peaks during DSC test.The reactions between lithiated graphite and LiPF_(6) and ethylene carbonate are found to be responsible for the first two exothermic peaks,while the third exothermic peak is attributed to the reaction between lithiated graphite and binder.In contrast,diethylene carbonate and ethyl methyl carbonate contribute little to the total heat generation of graphite-electrolyte reactions.The reaction mechanism between lithiated graphite and electrolyte,including the major reaction equations and gas products,are summarized.Finally,DSC tests on samples with various amounts of electrolyte are performed to clarify the quantitative relationship between lithiated graphite and electrolyte during the exothermic reactions.2.5 mg of lithiated graphite (Li_(0.8627)C_(6)) can fully react with around 7.2 mg electrolyte,releasing a heat generation of 2491 J g^(-1).The results presented in this study can provide useful guidance for the safety improvement of lithium-ion batteries. | Yuejiu Zheng Zhihe Shi Dongsheng Ren Jie Chen Xiang Liu Xuning Feng Li Wang Xuebing Han Languang Lu Xiangming He Minggao Ouyang | 2022 | Journal of Energy Chemistry2022，31，6： | 1 |
| 19 | Atp6i deficient mouse model uncovers transforming growth factor-β1/Smad2/3 as a key signaling pathway regulating odontoblast differentiation and tooth root formation显示文摘The biomolecular mechanisms that regulate tooth root development and odontoblast differentiation are poorly understood.We found that Atp6i deficient mice(Atp6i^(−/−))arrested tooth root formation,indicated by truncated Hertwig’s epithelial root sheath(HERS)progression.Furthermore,Atp6i deficiency significantly reduced the proliferation and differentiation of radicular odontogenic cells responsible for root formation.Atp6i^(−/−)mice had largely decreased expression of odontoblast differentiation marker gene expression profiles(Col1a1,Nfic,Dspp,and Osx)in the alveolar bone.Atp6i^(−/−)mice sample RNA-seq analysis results showed decreased expression levels of odontoblast markers.Additionally,there was a significant reduction in Smad2/3 activation,inhibiting transforming growth factor-β(TGF-β)signaling in Atp6i^(−/−)odontoblasts.Through treating pulp precursor cells with Atp6i^(−/−)or wild-type OC bone resorption-conditioned medium,we found the latter medium to promote odontoblast differentiation,as shown by increased odontoblast differentiation marker genes expression(Nfic,Dspp,Osx,and Runx2).This increased expression was significantly blocked by anti-TGF-β1 antibody neutralization,whereas odontoblast differentiation and Smad2/3 activation were significantly attenuated by Atp6i^(−/−)OC conditioned medium.Importantly,ectopic TGF-β1 partially rescued root development and root dentin deposition of Atp6i^(−/−)mice tooth germs were transplanted under mouse kidney capsules.Collectively,our novel data shows that the prevention of TGF-β1 release from the alveolar bone matrix due to OC dysfunction may lead to osteopetrosis-associated root formation via impaired radicular odontoblast differentiation.As such,this study uncovers TGF-β1/Smad2/3 as a key signaling pathway regulating odontoblast differentiation and tooth root formation and may contribute to future therapeutic approaches to tooth root regeneration. | Jue Wang Abigail McVicar Yilin Chen Hong-Wen Deng Zhihe Zhao Wei Chen Yi-Ping Li | 2023 | International Journal of Oral Science2023，15，3： | 0 |
| 20 | OH regulator of highly dispersed Ru sites on host Pd nanocrystals for selective ethanol electro-oxidation显示文摘The ethanol oxidation reaction(EOR)is crucial in direct alcohol fuel cells and chemical production.However,the electro-oxidation of ethanol molecules to produce acetaldehyde and carbon monoxide can poison the active sites of nanocatalysts,resulting in reduced performance and posing challenges in achieving high activity and selectivity for ethanol oxidation.In this study,we employed a dynamic seed-mediated method to precisely modify highly dispersed Ru sites onto well-defined Pd nanocrystals.The oxyphilic Ru sites serve as'OH valves',regulating water dissociation,while the surrounding Pd atomic arrangements control electronic states for the oxidation dehydrogenation of carbonaceous intermediates.Specifically,Ru0.040@Pd nanocubes(Ru:Pd=0.04 at.%),featuring(100)facets in Ru-Pd4 configurations,demonstrate an outstanding mass activity of 6.53 A·mgPd^(-1) in EOR under alkaline conditions,which is 6.05 times higher than that of the commercial Pd/C catalyst(1.08 A·mgPd-1).Through in-situ experiments and theoretical investigations,we elucidate that the hydrophilic Ru atoms significantly promote the dynamic evolution of H_(2)O dissociation into OHads species,while the electron redistribution from Ru to adjacent Pd concurrently adjusts the selective oxidation of C_(2) intermediates.This host-guest interaction accelerates the subsequent oxidation of carbonaceous intermediates(CH_(3)CO_(ads))to acetate,while preventing the formation of toxic*CHx and*CO species,which constitutes the rate-determining step. | Zhihe Xiao Yueguang Chen Renjie Wu Yuwei He Chunfeng Shi Leyu Wang | 2024 | Nano Research2024，17，5： | 0 |
