| 1 | Constitutive model for methane desorption and diffusion based on pore structure differences between soft and hard coal显示文摘This paper aims to improve the accuracy and applicability of gas diffusion mathematical models from coal particles. Firstly, a new constitutive model for gas diffusion from coal particles with tri-disperse pore structure is constructed by considering the difference in characteristics between soft coal and hard coal.The analytical solution is then derived, that is, the quantitative relationship between gas diffusion rate(Qt/Q_∞) and diffusion time(t), The pore structure parameters of soft coal and hard coal from Juji coal mine are determined. Gas diffusion rules are numerically calculated and investigated by physical simulation methods. Lastly, the applicability of this model is verified. The results show that the homogeneous model only applies to the gas diffusion process of hard coal during the initial 10 min. The calculation results from this model and the physical experimental results of soft coal and hard coal are nearly identical during the initial 30 min. | Liu Yanwei Wang Dandan Hao Fuchang Liu Mingju Mitri Hani S. | 2017 | International Journal of Mining Science and Technology2017，27，6： | 8 |
| 2 | A cyclodextrin-based nanoformulation achieves co-delivery of ginsenoside Rg3 and quercetin for chemo-immunotherapy in colorectal cancer显示文摘The immune checkpoint blockade therapy has profoundly revolutionized the field of cancer immunotherapy. However, despite great promise for a variety of cancers, the efficacy of immune checkpoint inhibitors is still low in colorectal cancer(CRC). This is mainly due to the immunosuppressive feature of the tumor microenvironment(TME). Emerging evidence reveals that certain chemotherapeutic drugs induce immunogenic cell death(ICD), demonstrating great potential for remodeling the immunosuppressive TME. In this study, the potential of ginsenoside Rg3(Rg3) as an ICD inducer against CRC cells was confirmed using in vitro and in vivo experimental approaches. The ICD efficacy of Rg3 could be significantly enhanced by quercetin(QTN) that elicited reactive oxygen species(ROS). To amelioratein vivo delivery barriers associated with chemotherapeutic drugs, a folate(FA)-targeted polyethylene glycol(PEG)-modified amphiphilic cyclodextrin nanoparticle(NP) was developed for co-encapsulation of Rg3 and QTN. The resultant nanoformulation(CD-PEG-FA.Rg3.QTN) significantly prolonged blood circulation and enhanced tumor targeting in an orthotopic CRC mouse model, resulting in the conversion of immunosuppressive TME. Furthermore, the CD-PEG-FA.Rg3.QTN achieved significantly longer survival of animals in combination with Anti-PD-L1. The study provides a promising strategy for the treatment of CRC. | Dandan Sun Yifang Zou Liu Song Shulan Han Hao Yang Di Chu Yun Dai Jie Ma Caitriona M.O’Driscoll Zhuo Yu Jianfeng Guo | 2022 | Acta Pharmaceutica Sinica B2022，12，1： | 8 |
| 3 | Atmospheric deposition of inorganic nitrogen in a semi-arid grassland of Inner Mongolia, China显示文摘Due to increasing global demand for crop production and energy use, more and more reactive nitrogen(Nr) has been generated and emitted to the environment. As a result, global atmospheric nitrogen(N) deposition has tripled since the industrial revolution and the ecological environment and human health have been harmed. In this study, we measured dry and wet/bulk N deposition from July 2013 to December 2015 in a semi-arid grassland of Duolun County, Inner Mongolia, China. The samples of dry and wet/bulk N deposition were collected monthly with a DELTA(DEnuder for Long Term Atmospheric sampling) system and with Gradko passive samplers and a precipitation gauge. The measured results show that the annual mean concentrations of NH_3, NO_2, HNO_3, particulate NH_4^+(pNH_4^+) and particulate NO_3^-(pNO_3^-) in atmosphere were 2.33, 1.90, 0.18, 1.42 and 0.42 μg N/m3, respectively, and that the annual mean volume-weighted concentrations of NH_4^+-N and NO_3^--N in precipitation were 2.71 and 1.99 mg N/L, respectively. The concentrations of Nr components(including NH_3, NO_2, HNO_3, p NH_4^+, pNO_3^-, NH_4^+-N and NO_3^--N) exhibited different seasonal variations. Specifically, NO_2 and HNO_3 exhibited higher concentrations in autumn than in summer, while the other Nr components(NH_3, pNH_4^+, pNO_3^-, NH_4^+-N and NO_3^--N) showed the highest values in summer. Based on measured concentrations of Nr components and their deposition velocities estimated using the GEOS-Chem global atmospheric chemical transport model, the calculated annual mean dry deposition fluxes were 3.17, 1.13, 0.63, 0.91 and 0.36 kg N/(hm^2·a) for NH_3, NO_2, HNO_3, p NH_4^+ and pNO_3^-, respectively, and the calculated annual mean wet/bulk deposition fluxes were 5.37 and 3.15 kg N/(hm^2·a) for NH_4^+-N and NO_3^--N, respectively. The estimated annual N deposition(including dry N deposition and wet/bulk N deposition) reached 14.7 kg N/(hm^2·a) in grassland of Duolun County, approaching to the upper limit of the N critical load(10–15 kg N/(hm^2·a)). Dry and wet/bulk deposition fluxes of all Nr components(with an exception of HNO_3) showed similar seasonal variations with the maximum deposition flux in summer and the minimum in winter. Reduced Nr components(e.g., gaseous NH_3 and p NH_4^+ in atmosphere and NH_4^+-N in precipitation) dominated the total N deposition at the sampling site(accounted for 64% of the total N deposition), suggesting that the deposited atmospheric Nr mainly originated from agricultural activities. Considering the projected future increases in crop and livestock production in Inner Mongolia, the ecological and human risks to the negative effects of increased N deposition could be increased if no mitigation measures are taken. | ZHANG Yibo XU Wen WEN Zhang WANG Dandan HAO Tianxiang TANG Aohan LIU Xuejun | 2017 | Journal of Arid Land2017，9，6： | 5 |
| 4 | Lead halide perovskite nanowires stabilized by block copolymers for Langmuir-Blodgett assembly显示文摘The rapid development of solar cells based on lead halide perovskites(LHPs)has prompted very active research activities in other closely-related fields.Colloidal nanostructures of such materials display superior optoelectronic properties.Especially,onedimensional(1D)LHPs nanowires show anisotropic optical properties when they are highly oriented.However,the ionic nature makes them very sensitive to external environment,limiting their large scale practical applications.Here,we introduce an amphiphilic block copolymer,polystyrene-block-poly(4-vinylpyridine)(PS-P4VP),to chemically modify the surface of colloidal CsPbBr3 nanowires.The resulting core-shell nanowires show enhanced photoluminescent emission and good colloidal stability against water.Taking advantage of the stability enhancement,we further applied a modified Langmuir-Blodgett technique to assemble monolayers of highly aligned nanowires,and studied their anisotropic optical properties. | Hao Liu Martin Siron Mengyu Gao Dylan Lu Yehonadav Bekenstein Dandan Zhang Letian Dou A.Paul Alivisatos Peidong Yang | 2020 | Nano Research2020，13，5： | 4 |
| 5 | Retina-Inspired Organic Heterojunction-Based Optoelectronic Synapses for Artificial Visual Systems显示文摘For the realization of retina-inspired neuromorphic visual systems which simulate basic functions of human visual systems,optoelectronic synapses capable of combining perceiving,processing,and memorizing in a single device have attracted immense interests.Here,optoelectronic synaptic transistors based on tris(2-phenylpyridine)iridium(Ir(ppy)_(3))and poly(3,3-didodecylquarterthiophene)(PQT-12)heterojunction structure are presented.The organic heterojunction serves as a basis for distinctive synaptic characteristics under different wavelengths of light.Furthermore,synaptic transistor arrays are fabricated to demonstrate their optical perception efficiency and color recognition capability under multiple illuminating conditions.The wavelength-tunability of synaptic behaviors further enables the mimicry of mood-modulated visual learning and memorizing processes of humans.More significantly,the computational dynamics of neurons of synaptic outputs including associated learning and optical logic functions can be successfully demonstrated on the presented devices.This work may locate the stage for future studies on optoelectronic synaptic devices toward the implementation of artificial visual systems. | Junyao Zhang Yang Lu Shilei Dai Ruizhi Wang Dandan Hao Shiqi Zhang Lize Xiong Jia Huang | 2021 | Research2021，，1： | 3 |
| 6 | Photodegradation of benzene by TiO_2 nanoparticles prepared by flame CVD process显示文摘Photodegradation of benzene at ppb levels by mixed-phase TiO 2 nanoparticles, synthesized by the oxidation of TiCl 4 in propane/air turbulent flame chemical vapor deposition (CVD) process, is investigated experimentally by using a tubular photoreactor with thin TiO 2 films coated on the reactor wall by sedimentation. Effects of inlet benzene concentration from 10 to 300 g/m 3 , rutile mass fraction from about 20 to 50% and photoluminescence (PL) intensity of TiO 2 nanoparticles on degradation degree are examined under the conditions of 70% relative humidity, 38 g/cm 2 catalyst loading, 24 mW/cm 2 UV irradiation of 254 nm and 5.7 s residence time in the reactor. Based on experimental results, separation of photo-induced electron (e- ) and hole (h + ) pairs by rutile phase is discussed as photo-induced electron (e- ) in anatase phase will migrate to rutile surface due to that the potential of conductive band of rutile is lower than that of anatase, leading to more holes ready on anatase surface for oxidation reactions. | Hongyong Xie Luping Zhu Lingling Wang Shengwen Chen Dandan Yang Lijun Yang Guilan Gao Hao Yuan | 2011 | Particuology2011，9，1： | 3 |
| 7 | A hybrid genipin-crosslinked dual-sensitive hydrogel/nanostructured lipid carrier ocular drug delivery platform显示文摘The objective of this study was to develop a novel hybrid genipin-crosslinked dual-sensitive hydrogel/nanostructured lipid carrier(NLC) drug delivery platform. An ophthalmic antiinflammatory drug, baicalin(BN) was chosen as the model drug. BN –NLC was prepared using melt-emulsification combined with ultra-sonication technique. Additionally, a dual pH-and thermo-sensitive hydrogel composed of carboxymethyl chitosan(CMCS) and poloxamer 407(F127) was fabricated by a cross-linking reaction with a nontoxic crosslinker genipin(GP). GP-CMCS/F127 hydrogel was characterized by FTIR, NMR, XRD and SEM. The swelling studies showed GP-CMCS/F127 hydrogel was both pH-and thermo-sensitive. The results of in vitro release suggested BN –NLC gel can prolong the release of baicalin comparing with BN eye drops and BN –NLC. Ex vivo cornea permeation study was evaluated using Franz diffusion cells. The apparent permeability coefficient(Papp) of BN –NLC gel was much higher(4.46-fold) than that of BN eye drops. Through the determination of corneal hydration levels, BN –NLC gel was confirmed that had no significant irritation to cornea. Ex vivo precorneal retention experiments were carried out by a flow-through approach. The results indicated that the NLC-based hydrogel can prolong precorneal residence time. In conclusion, the hybrid NLCbased hydrogel has a promising potential for application in ocular drug delivery. | Yibin Yu Ruoxi Feng Jinyu Li Yuanyuan Wang Yiming Song Guoxin Tan Dandan Liu Wei Liu Xinggang Yang Hao Pan Sanming Li | 2019 | Asian Journal of Pharmaceutical Sciences2019，14，4： | 3 |
| 8 | Interfacial Voids Trigger Carbon-Based, All-Inorganic Cs Pb IBr2 Perovskite Solar Cells with Photovoltage Exceeding 1.33 V显示文摘A novel interface design is proposed for carbon-based,all-inorganic CsPbIBr2 perovskite solar cells(PSCs)by introducing interfacial voids between TiO2 electron transport layer and CsPbIBr2 absorber.Compared with the general interfacial engineering strategies,this design exempts any extra modification layer in final PSC.More importantly,the interfacial voids produced by thermal decomposition of 2-phenylethylammonium iodide trigger three beneficial e ects.First,they promote the light scattering in CsPbIBr2 film and thereby boost absorption ability of the resulting CsPbIBr2 PSCs.Second,they suppress recombination of charge carriers and thus reduce dark saturation current density(J0)of the PSCs.Third,interfacial voids enlarge built-in potential(Vbi)of the PSCs,awarding increased driving force for dissociating photo-generated charge carriers.Consequently,the PSC yields the optimized e ciency of 10.20%coupled with an open-circuit voltage(Voc)of 1.338 V.The Voc achieved herein represents the best value among CsPbIBr2 PSCs reported earlier.Meanwhile,the non-encapsulated PSCs exhibit an excellent stability against light,thermal,and humidity stresses,since it remains^97%or^94%of its initial e ciency after being heated at 85℃for 12 h or stored in ambient atmosphere with relative humidity of 30–40%for 60 days,respectively. | Weidong Zhu Zeyang Zhang Dandan Chen Wenming Chai Dazheng Chen Jincheng Zhang Chunfu Zhang Yue Hao | 2020 | Nano-Micro Letters2020，12，7： | 3 |

| 10 | How delaying post-silking senescence in lower leaves of maize plants increases carbon and nitrogen accumulation and grain yield显示文摘Planting maize at high densities leads to early leaf senescence,and the resulting reduction in the number of lower leaves affects the plant’s root function and lowers its grain yield.However,the nature of the process by which lower leaf senescence affects biomass accumulation and grain yield formation in maize is not clear.This study aimed to shed light on how these factors are related by investigating the effects of the plant growth regulator 6-benzyladenine(6-BA)on the senescence of lower leaves of maize plants.In two maize cultivars planted at densities of 67,500(low density,LD)and 90,000(high density,HD)plants ha^(-1),plants treated with 6-BA maintained a high green leaf area index(LAI)longer than control(CK)plants,enabling them to maintain a higher photosynthetic rate for a longer period of time and produce more biomass before reaching physiological maturity.Spraying the lower leaves of maize plants with a 6-BA solution increased the distribution of;C-photosynthates to their roots,lower leaves and bracts,a result that can be ascribed to a decreased retention of;C-photosynthates in the stem and grain.In both seasons of the experiment,maize plants treated with 6-BA accumulated more N in grain and maintained a higher N content in roots and leaves,especially in lower leaves,than CK.Increased C assimilation in the lower leaves may explain why N uptake in plants subjected to the 6-BA treatment exceeded that in CK plants and why both photosynthesis rate and dry matter accumulation were maintained throughout grain filling.Our results suggest that a suitable distribution of C and N in leaves post-silking may maintain plant root function,increase N use efficiency,maximize the duration of high LAI,and increase grain yield. | Rongfa Li Dandan Hu Hao Ren Qinglong Yang Shuting Dong Jiwang Zhang Bin Zhao Peng Liu | 2022 | The Crop Journal2022，10，3： | 2 |

| 13 | High-loading Co-doped NiO nanosheets on carbon-welded carbon nanotube framework enabling rapid charge kinetic for enhanced supercapacitor performance显示文摘Developing high power and energy supercapacitors(SCs)is a long-pursued goal for the application in transportation and energy storage station.Herein,a rationally-designed Co-doped nickel oxide nanosheets@carbon-welded carbon nanotube foam(Co-doped NiO@WCNTF)as freestanding electrode is successfully prepared for high power and energy SCs.The WCNTF framework with high specific surface area provides three dimensional highly conductive network for fast charge transport and ensures high loading of active materials(9.2 mg/cm2).Moreover,porous Co-doped NiO nanosheets uniformly anchored on the WCNTF framework enable rapid charge kinetics due to the high intrinsic conductivity of Co-doped Ni O nanosheets and their good contact with conductive WCNTF substrate.As a result,the unique integrated electrode with 3D architecture exhibits an ultrahigh specific capacitance of 11.45 F/cm2 at 5 mA/cm2,outstanding rate capability(11.45 F/cm2 at 5 mA/cm2 and a capacitance retention of 86.2%at 30 mA/cm2)and good cycling stability,suggesting great potential for high performance supercapacitor. | Hao Xu Yufang Cao Yong Li Pei Cao Dandan Liu Yongyi Zhang Qing wen Li | 2020 | Journal of Energy Chemistry2020，29，11： | 2 |
| 14 | Applications of pain-related evoked potentials and short-latency somatosensory evoked potentials in acupuncture research:a narrative review显示文摘OBJECTIVE:To review and discuss the Chinese and English literature on the use of pain-related evoked potentials(PREP) and short-latency somatosensory EP(SLSEP) in acupuncture research.METHODS:China National Knowledge Infrastructure Database and MEDLINE were searched for the following key words:acupuncture and PREP or SLSEP.RESULTS:Thirty-seven articles were included in the review.Researchers usually use PREPs to study the analgesic effect of acupuncture,observe influential factors,or for mechanistic exploration.In the SLSEP studies,researchers focused on response characteristics of acupuncture,acupoint specificity,and influential factors of the treatment.There were some problems with the study design and conclusions.CONCLUSION:Researchers could use PREP and SLSEP to objectively validate the effects of acupuncture and explore its mechanisms using nerve electrophysiology.Further studies can benefit from observing more acupoints' effects using PREPs or SLSEPs and investigating the placebo effect of acupuncture. | Lin Chi Ma Liangxiao Zhu Shipeng Hu Nijuan Wang Pei Zhang Peng Qi Dandan Hao Jie Li Jing Xin Siyuan Zhu Jiang | 2015 | Journal of Traditional Chinese Medicine2015，35，5： | 2 |
| 15 | Formative pluripotent stem cells show features of epiblast cells poised for gastrulation显示文摘The pluripotency of mammalian early and late epiblast could be recapitulated by naïve embryonic stem cells(ESCs)and primed epiblast stem cells(EpiSCs),respectively.However,these two states of pluripotency may not be sufficient to reflect the full complexity and developmental potency of the epiblast during mammalian early development.Here we report the establishment of self-renewing formative pluripotent stem cells(fPSCs)which manifest features of epiblast cells poised for gastrulation.fPSCs can be established from different mouse ESCs,pre-/early-gastrula epiblasts and induced PSCs.Similar to pre-/early-gastrula epiblasts,fPSCs show the transcriptomic features of formative pluripotency,which are distinct from naïve ESCs and primed EpiSCs.fPSCs show the unique epigenetic states of E6.5 epiblast,including the super-bivalency of a large set of developmental genes.Just like epiblast cells immediately before gastrulation,fPSCs can efficiently differentiate into three germ layers and primordial germ cells(PGCs)in vitro.Thus,fPSCs highlight the feasibility of using PSCs to explore the development of mammalian epiblast. | Xiaoxiao Wang Yunlong Xiang Yang Yu Ran Wang Yu Zhang Qianhua Xu Hao Sun Zhen-Ao Zhao Xiangxiang Jiang Xiaoqing Wang Xukun Lu Dandan Qin Yujun Quan Jiaqi Zhang Ng Shyh-Chang Hongmei Wang Naihe Jing Wei Xie Lei Li | 2021 | Cell Research2021，31，5： | 2 |

| 17 | Photocrosslinkable Col/PCL/Mg composite membrane providing spatiotemporal maintenance and positive osteogenetic effects during guided bone regeneration显示文摘Guided bone regeneration membranes have been effectively applied in oral implantology to repair bone defects.However,typical resorbable membranes composed of collagen(Col)have insufficient mechanical properties and high degradation rate,while non-resorbable membranes need secondary surgery.Herein,we designed a photocrosslinkable collagen/polycaprolactone methacryloyl/magnesium(Col/PCLMA/Mg)composite membrane that provided spatiotemporal support effect after photocrosslinking.Magnesium particles were added to the PCLMA solution and Col/PCLMA and Col/PCLMA/Mg membranes were developed;Col membranes and PCL membranes were used as controls.After photocrosslinking,an interpenetrating polymer network was observed by scanning electron microscopy(SEM)in Col/PCL and Col/PCL/Mg membranes.The elastic modulus,swelling behavior,cytotoxicity,cell attachment,and cell proliferation of the membranes were evaluated.Degradation behavior in vivo and in vitro was monitored according to mass change and by SEM.The membranes were implanted into calvarial bone defects of rats for 8 weeks.The Col/PCL and Col/PCL/Mg membranes displayed much higher elastic modulus(p<0.05),and a lower swelling rate(p<0.05),than Col membranes,and there were no differences in cell biocompatibility among groups(p>0.05).The Col/PCL and Col/PCL/Mg membranes had lower degradation rates than the Col membranes,both in vivo and in vitro(p<0.05).The Col/PCL/Mg groups showed enhanced osteogenic capability compared with the Col groups at week 8(p<0.05).The Col/PCL/Mg composite membrane represents a new strategy to display space maintenance and enhance osteogenic potential,which meets clinical needs. | Feilong Wang Dandan Xia Siyi Wang Ranli Gu Fan Yang Xiao Zhao Xuenan Liu Yuan Zhu Hao Liu Yongxiang Xu Yunsong Liu Yongsheng Zhou | 2022 | Bioactive Materials2022，7，7： | 1 |

| 19 | Moire-pattern-modulated electronic structures in Sb_(2)Te_(3)/graphene heterostructure显示文摘Moire superlattice has recently been found in topological insulators,which can lead to periodic modulation on the electronic structure.In this work,we report the low-temperature scanning tunneling microscopy study of Sb_(2)Te_(3) films grown on graphitized 4H-SiC.We find that substrate temperature can strongly influence the rotation angles between Sb_(2)Te_(3) film and graphene substrate.Three kinds of moire patterns are observed at the first quintuple layer Sb_(2)Te_(3) film under different substrate temperatures.One shows complicated patterns with a rotation angle of nearly 0°relative to the substrate,another just exhibits simple 1 ×1 structure with a rotation angle of 30°.Other rotation angle like 8.2°is observed at higher substrate temperature as well,which is relatively rare.Comparison of the d//dV curves from Sb_(2)Te_(3) films with different moire patterns indicates that the superstructure can offer degrees of freedom in tailoring electronic structure.This work may stimulate the further study on the moire modulation to the electronic properties of topological insulators. | Yin Yin Guanyong Wang Chen Liu Haili Huang Jiayi Chen Jiaying Liu Dandan Guan Shiyong Wang Yaoyii Li Canhua Liu Hao Zheng Jinfeng Jia | 2022 | Nano Research2022，15，2： | 1 |
| 20 | Identification of two migratory colon ILC2 populations differentially expressing IL-17A and IL-5/IL-13显示文摘Group 2 innate lymphoid cells(ILC2s)play important tissue resident roles in anti-parasite immunity,allergic immune response,tissue homeostasis,and tumor immunity.ILC2s are considered tissue resident cells with little proliferation at steady state.Recent studies have shown that a subset of small intestinal ILC2s could leave their residing tissues,circulate and migrate to different organs,including lung,liver,mesenteric LN and spleen,upon activation.However,it remains unknown whether other ILC populations with migratory behavior exist.In this study,we find two major colon ILC2 populations with potential to migrate to the lung in response to IL-25 stimulation.One subset expresses IL-17A and resembles inflammatory ILC2s(iILC2s)but lacks CD27 expression,whereas the other expresses CD27 but not IL-17A.In addition,the IL-17A^(+)ILC2s express lower levels of CD127,CD25,and ST2 than CD27^(+)ILC2s,which express higher levels of IL-5 and IL-13.Surprisingly,we found that both colon ILC2 populations still maintained their colonic features of preferential expression of IL-17A and CD27,IL-5/IL-13,respectively.Together,our study identifies two migratory colon ILC2 subsets with unique surface markers and cytokine profiles which are critical in regulating lung and colon immunity and homeostasis. | Hongzhi Liu Liang Li Yanyun Hao Jialu Li Zhaoyuan Liu Jingjing Qi Jingjing Zhang Ningbo Wu Dandan Wu Caixia Gao Lei Chen Lei Shen Jinke Cheng Bing Su | 2023 | Science China(Life Sciences)2023，66，1： | 1 |
