| 1 | Ultrafast epitaxial growth of metre-sized single-crystal graphene on industrial Cu foil显示文摘A foundation of the modern technology that uses single-crystal silicon has been the growth of highquality single-crystal Si ingots with diameters up to 12 inches or larger. For many applications of graphene, large-area high-quality(ideally of single-crystal) material will be enabling. Since the first growth on copper foil a decade ago, inch-sized single-crystal graphene has been achieved. We present here the growth, in 20 min, of a graphene film of(5 ×50) cm^2 dimension with >99% ultra-highly oriented grains.This growth was achieved by:(1) synthesis of metre-sized single-crystal Cu(1 1 1) foil as substrate;(2)epitaxial growth of graphene islands on the Cu(1 1 1) surface;(3) seamless merging of such graphene islands into a graphene film with high single crystallinity and(4) the ultrafast growth of graphene film.These achievements were realized by a temperature-gradient-driven annealing technique to produce single-crystal Cu(1 1 1) from industrial polycrystalline Cu foil and the marvellous effects of a continuous oxygen supply from an adjacent oxide. The as-synthesized graphene film, with very few misoriented grains(if any), has a mobility up to ~23,000 cm^2 V^(-1)s^(-1)at 4 K and room temperature sheet resistance of ~230 Ω/□. It is very likely that this approach can be scaled up to achieve exceptionally large and high-quality graphene films with single crystallinity, and thus realize various industrial-level applications at a low cost. | Xiaozhi Xu Zhihong Zhang Jichen Dong Ding Yi Jingjing Niu Muhong Wu Li Lin Rongkang Yin Mingqiang Li Jingyuan Zhou Shaoxin Wang Junliang Sun Xiaojie Duan Peng Gao Ying Jiang Xiaosong Wu Hailin Peng Rodney S.

| 2 | A new bone repair scaffold combined with chitosan/ hydroxyapatite and sustained releasing icariin显示文摘Icariin, a plant-derived flavonol glycoside, has been proved as an osteoinductive agent for bone tissue engineering. A new bone repair scaffold was generated by thorough mixing of icariin and chitosan/ hydroxyapatite (icariin-CS/HA) using freeze-drying technigue. Characteristics of morphology, mechanical properties, biocompatibility, drug release behavior and bone repair abilities in vivo were evaluated. The results show that drug loading process of icariin did not affect physical structure of CS/HA composite significantly but decreased mechanical properies of CS/HA composite, which happened with a high dosage; icariin-CS/HA had favorable cell compatibility and promoted osteogenic differentiation of hBMSCs; the controlled release of icariin was satisfactory and the release retained after 90 d in vitro. In addition, icariin-CS/HA scaffolds had favorable osteoconduction and osteoinduction in vivo, and could fill bone defect sites and stimulate newborn bone tissues formation at early stage. On the basis of these data, icariin-CS/HA is believed to be an optical bone repair scaffold for tissue engineering. | WU Tao NAN KaiHui CHEN JingDi JIN Dan JIANG Shan ZHAO PeiRan XU JunChang DU Hao ZHANG XiaoQiang LI JianWei PEI GuoXian | 2009 | Chinese Science Bulletin2009，54，17： | 14 |
| 3 | A Novel Pre-control Method of Vehicle Dynamics Stability Based on Critical Stable Velocity during Transient Steering Maneuvering显示文摘The current research of direct yaw moment control(DYC) system focus on the design of target yaw moment and the distribution of wheel brake force. The differential braking intervention can effectively improve the lateral stability of the vehicle, however, the effect of DYC can be improved a step further by applying the control of vehicle longitudinal velocity. In this paper, the relationship between the vehicle longitudinal velocity and lateral stability is studied, and the simulation results show that a decrease of 5 km/h of longitudinal velocity at a particular situation can bring 100° increasing of stable steering upper limit. A critical stable velocity considering the effect of steering and yaw rate measurement is defined to evaluate the risk of losing steer-ability or stability. A novel velocity pre-control method is proposed by using a hierarchical pre-control logic and is integrated with the traditional DYC system. The control algorithm is verified through a hardware in-the-loop simulation system. Double lane change(DLC) test results on both high friction coefficient(μ) and low μ roads show that by using the pre-control method, the steering effort in DLC test can be reduced by 38% and 51% and the peak value of brake pressure control can be reduced by 20% and 12% respectively on high μ and low μ roads, the lateral stability is also improved. This research proposes a novel DYC system with lighter control effort and better control effect. | CHEN Jie SONG Jian LI Liang RAN Xu JIA Gang WU Kaihui | 2016 | Chinese Journal of Mechanical Engineering2016，29，3： | 8 |
| 4 | Fluxes of methane,carbon dioxide and nitrous oxide in an alpine wetland and an alpine grassland of the Tianshan Mountains,China显示文摘Methane(CH4), carbon dioxide(CO2) and nitrous oxide(N2O) are known to be major greenhouse gases that contribute to global warming. To identify the flux dynamics of these greenhouse gases is, therefore, of great significance. In this paper, we conducted a comparative study on an alpine grassland and alpine wetland at the Bayinbuluk Grassland Eco-system Research Station, Chinese Academy of Sciences. By using opaque, static, manual stainless steel chambers and gas chromatography, we measured the fluxes of CH4, N2O and CO2 from the grassland and wetland through an in situ monitoring study from May 2010 to October 2012. The mean flux rates of CH4, N2O and CO2 for the experimental alpine wetland in the growing season(from May to October) were estimated at 322.4 μg/(m2?h), 16.7 μg/(m2?h) and 76.7 mg/(m2?h), respectively; and the values for the alpine grassland were –88.2 μg/(m2?h), 12.7 μg/(m2?h), 57.3 mg/(m2?h), respectively. The gas fluxes showed large seasonal and annual variations, suggesting weak fluxes in the non-growing season. The relationships between these gas fluxes and environmental factors were analyzed for the two alpine ecosystems. The results showed that air temperature, precipitation, soil temperature and soil moisture can greatly influence the fluxes of CH4, N2O and CO2, but the alpine grassland and alpine wetland showed different feedback mechanisms under the same climate and environmental conditions. | GuiXiang HE KaiHui LI XueJun LIU YanMing GONG YuKun HU | 2014 | Journal of Arid Land2014，6，6： | 7 |
| 5 | Carbon Storage and Vertical Distribution in Three Shrubland Communities in Gurbantünggüt Desert,Uygur AutonomousRegion of Xinjiang,Northwest China显示文摘This study was carried out in the Gurbantünggüt Desert,Uygur Autonomous Region of Xinjiang,Northwest China in August,2009.To quantify the storage,contribution and vertical distribution patterns of plant biomass carbon (PBC)and soil organic carbon(SOC)in the study area,we investigated the carbon concentrations and its vertical distribution in three different desert shrubland communities dominated by Reaumuria soongorica,Haloxylon ammodendron+R.soongorica and Tamarix ramosissima+R.soongorica,respectively.We analyzed vertical distribution of root biomass carbon and soil carbon contents by excavating soil profiles for each dominated community.The results show that SOC is considerably the larger carbon pool in the soil layers of 1.0-3.0 m(the mean value of three shrubland communities is 38.46%)and 3.0-5.0 m(the mean value is 40.24%).In contrast,70.74%of belowground biomass carbon storage in 0-1.0 m layer,and its content decrease with increasing soil depth.The Haloxylon ammodendron+R. soongorica shrubland community has the highest belowground biomass carbon among three selected communities. This study highlights the importance of SOC stored in deep soil layers(lower than 3.0 m from the surface)in arid shrubland communities in the global carbon balance.In addition,it provides the data support for revealing deep soil solid carbon potential,and offers scientific basis for the further research in the carbon cycle of terrestrial ecosystem. | GONG Yanming HU Yukun FANG Fei LIU Yanyan LI Kaihui ZHANG Guangming | 2012 | Chinese Geographical Science2012，22，5： | 6 |
| 6 | Abrogation of Hn RNP L enhances anti-PD-1 therapy efficacy via diminishing PD-L1 and promoting CD8^(+) T cell-mediated ferroptosis in castration-resistant prostate cancer显示文摘Owing to incurable castration-resistant prostate cancer(CRPC)ultimately developing after treating with androgen deprivation therapy(ADT),it is vital to devise new therapeutic strategies to treat CRPC.Treatments that target programmed cell death protein 1(PD-1)and programmed death ligand-1(PD-L1)have been approved for human cancers with clinical benefit.However,many patients,especially prostate cancer,fail to respond to anti-PD-1/PD-L1 treatment,so it is an urgent need to seek a support strategy for improving the traditional PD-1/PD-L1 targeting immunotherapy.In the present study,analyzing the data from our prostate cancer tissue microarray,we found that PD-L1 expression was positively correlated with the expression of heterogeneous nuclear ribonucleoprotein L(Hn RNP L).Hence,we further investigated the potential role of Hn RNP L on the PD-L1 expression,the sensitivity of cancer cells to T-cell killing and the synergistic effect with anti-PD-1 therapy in CRPC.Indeed,Hn RNP L knockdown effectively decreased PD-L1 expression and recovered the sensitivity of cancer cells to T-cell killing in vitro and in vivo,on the contrary,Hn RNP L overexpression led to the opposite effect in CRPC cells.In addition,consistent with the previous study,we revealed that ferroptosis played a critical role in T-cell-induced cancer cell death,and Hn RNP L promoted the cancer immune escape partly through targeting YY1/PD-L1 axis and inhibiting ferroptosis in CRPC cells.Furthermore,Hn RNP L knockdown enhanced antitumor immunity by recruiting infiltrating CD8^(+)T cells and synergized with anti-PD-1 therapy in CRPC tumors.This study provided biological evidence that Hn RNP L knockdown might be a novel therapeutic agent in PD-L1/PD-1 blockade strategy that enhanced anti-tumor immune response in CRPC. | Xumin Zhou Libin Zou Hangyu Liao Junqi Luo Taowei Yang Jun Wu Wenbin Chen Kaihui Wu Shengren Cen Daojun Lv Fangpeng Shu Yu Yang Chun Li Bingkun Li Xiangming Mao | 2022 | Acta Pharmaceutica Sinica B2022，12，2： | 4 |
| 7 | Genome and transcriptome of Papaver somniferum Chinese landrace CHM indicates that massive genome expansion contributes to high benzylisoquinoline alkaloid biosynthesis显示文摘Opium poppy(Papaver somniferum)is a source of morphine,codeine,and semisynthetic derivatives,including oxycodone and naltrexone.Here,we report the de novo assembly and genomic analysis of P.somniferum traditional landrace‘Chinese Herbal Medicine’.Variations between the 2.62 Gb CHM genome and that of the previously sequenced high noscapine 1(HN1)variety were also explored.Among 79,668 protein-coding genes,we functionally annotated 88.9%,compared to 68.8%reported in the HN1 genome.Gene family and 4DTv comparative analyses with three other Papaveraceae species revealed that opium poppy underwent two whole-genome duplication(WGD)events.The first of these,in ancestral Ranunculales,expanded gene families related to characteristic secondary metabolite production and disease resistance.The more recent species-specific WGD mediated by transposable elements resulted in massive genome expansion.Genes carrying structural variations and large-effect variants associated with agronomically different phenotypes between CHM and HN1 that were identified through our transcriptomic comparison of multiple organs and developmental stages can enable the development of new varieties.These genomic and transcriptomic analyses will provide a valuable resource that informs future basic and agricultural studies of the opium poppy. | Li Pei Baishi Wang Jian Ye Xiaodi Hu Lihong Fu Kui Li Zhiyu Ni Zhenlong Wang Yujie Wei Luye Shi Ying Zhang Xue Bai Mengwan Jiang Shuhui Wang Chunling Ma Shujin Li Kaihui Liu Wanshui Li Bin Cong | 2021 | Horticulture Research2021，8，1： | 4 |
| 8 | Algorithm for Calculating Torque Base in Vehicle Traction Control System显示文摘Existing research on the traction control system(TCS) mainly focuses on control methods, such as the PID control, fuzzy logic control, etc, aiming at achieving an ideal slip rate of the drive wheel over long control periods. The initial output of the TCS (referred to as the torque base in this paper), which has a great impact on the driving performance of the vehicle in early cycles, remains to be investigated. In order to improve the control performance of the TCS in the first several cycles, an algorithm is proposed to determine the torque base. First, torque bases are calculated by two different methods, one based on states judgment and the other based on the vehicle dynamics. The confidence level of the torque base calculated based on the vehicle dynamics is also obtained. The final torque base is then determined based on the two torque bases and the confidence level. Hardware-in-the-loop(HIL) simulation and vehicle tests emulating sudden start on low friction roads have been conducted to verify the proposed algorithm. The control performance of a PID-controlled TCS with and without the proposed torque base algorithm is compared, showing that the proposed algorithm improves the performance of the TCS over the first several cycles and enhances about 5% vehicle speed by contrast. The proposed research provides a more proper initial value for TCS control, and improves the performance of the first several control cycles of the TCS. | LI Hongzhi LI Liang SONG Jian WU Kaihui QIAO Yanjuan LIU Xingchun XIA Yongguang | 2012 | Chinese Journal of Mechanical Engineering2012，25，6： | 4 |
| 9 | Plant diversity-productivity patterns in the alpine steppe environment of the Central Tianshan Mountains显示文摘The biodiversity-productivity relationship is an important topic in the research of bio- diversity and ecosystem function. The plant diversity-productivity pattern is commonly unimodal and positively correlated. This paper researches the characteristics of plant diversity-productivity patterns in the Bayanbuluk alpine steppe in the central Tianshan Mountains, Xinjiang, China, and analyzes the effects of environmental factors on the distribution of plant communities, species composition, plant diversity and productivity in the steppe. The results show a positive correlation between plant diversity and productivity. DCCA (detrended canonical correspondence analysis) ordination reveals a significant relationship between the effects of air temperature, soil moisture content, available soil nitrogen, relative humidity and pH value on the distribution and composition of plant communities. There are significant correlations between the soil moisture content, relative humidity, pH value, air temperature and species richness and the aboveground biomass of Gramineae and Cyperaceae, and also significant correlations between the relative humidity, pH values and the total aboveground biomass of plant communities. | Hu, YuKun Li, KaiHui Gong, YanMing Yin, Wei | 2009 | Journal of Arid Land2009，1，1： | 3 |
| 10 | Auxin regulation and MdPIN expression during adventitious root initiation in apple cuttings显示文摘Adventitious root(AR)formation is critical for the efficient propagation of elite horticultural and forestry crops.Despite decades of research,the cellular processes and molecular mechanisms underlying AR induction in woody plants remain obscure.We examined the details of AR formation in apple(Malus domestica)M.9 rootstock,the most widely used dwarf rootstock for intensive production,and investigated the role of polar auxin transport in postembryonic organogenesis.AR formation begins with a series of founder cell divisions and elongation of the interfascicular cambium adjacent to vascular tissues.This process is associated with a relatively high indole acetic acid(IAA)content and hydrolysis of starch grains.Exogenous auxin treatment promoted this cell division,as well as the proliferation and reorganization of the endoplasmic reticulum and Golgi membrane.In contrast,treatment with the auxin transport inhibitor N-1-naphthylphthalamic acid(NPA)inhibited cell division in the basal region of the cuttings and resulted in abnormal cell divisions during the early stage of AR formation.In addition,PIN-FORMED(PIN)transcripts were differentially expressed throughout the whole AR development process.We also detected upregulation of MdPIN8 and MdPIN10 during induction;upregulation of MdPIN4,MdPIN5,and MdPIN8 during extension;and upregulation of all MdPINs during AR initiation.This research provides an improved understanding of the cellular and molecular underpinnings of the AR process in woody plants. | Ling Guan Yingjun Li Kaihui Huang Zong-Ming(Max)Cheng | 2020 | Horticulture Research2020，7，1： | 2 |
| 11 | Contrasting effects of nitrogen addition on litter decomposition in forests and grasslands in China显示文摘Nitrogen(N)addition has profound impacts on litter-mediated nutrient cycling.Numerous studies have reported different effects of N addition on litter decomposition,exhibiting positive,negative,or neutral effects.Previous meta-analysis of litter decomposition under N addition was mainly based on a small number of samples to allow comparisons among ecosystem types.This study presents the results of a meta-analysis incorporating data from 53 published studies(including 617 observations)across forests,grasslands,wetlands,and croplands in China,to investigate how environmental and experimental factors impact the effects of N addition on litter decomposition.Averaged across all of the studies,N addition significantly slows litter decomposition by 7.02%.Considering ecosystem types,N addition significantly accelerates litter decomposition by 3.70%and 11.22%in grasslands and wetlands,respectively,clearly inhibits litter decomposition by 14.53%in forests,and has no significant effects on litter decomposition in croplands.Regarding the accelerated litter decomposition rate in grasslands due to N addition,litter decomposition rate increases slightly with increasing rates of N addition.However,N addition slows litter decomposition in forests,but litter decomposition is at a significantly increasing rate with increasing amounts of N addition.The responses of litter decomposition to N addition are also influenced by the forms of N addition,experiential duration of N addition,humidity index,litter quality,and soil pH.In summary,N addition alters litter decomposition rate,but the direction and magnitude of the response are affected by the forms of N addition,the rate of N addition,ambient N deposition,experimental duration,and climate factors.Our study highlights the contrasting effects of N addition on litter decomposition in forests and grasslands.This finding could be used in biogeochemical models to better evaluate ecosystem carbon cycling under increasing N deposition due to the differential responses of litter decomposition to N addition rates and ecosystem types. | SU Yuan MA Xiaofei GONG Yanming LI Kaihui HAN Wenxuan LIU Xuejun | 2021 | Journal of Arid Land2021，13，7： | 2 |

| 13 | Atomic-scale imaging of the defect dynamics in ceria nanowires under heating by in situ aberration-corrected TEM显示文摘The defects in the ceria usually work as the active reaction sites in their industrial applications.In this article,we studied the formation and atomic process of the defects of ceria nanowires under heating by using in situ aberration-corrected transmission electron microscopy(Cs-TEM)method.With the temperature elevating,ceria nanowires are reduced and defects begin to appear and grow up.When temperature reaches 1,023 K,the defect morphology exhibits the rhombus or hexagon patterns,which are surrounded by{111}and{200}planes with lower surface energy,and the heated ceria still maintain the same cubic fluorite structure as their parent.It is also indicated that the formation of defects originates from the release of lattice oxygen and the volatilization of surface Ce ions.This work provides an important insight into designing ceria-based catalysts and ionic conductors. | Xiaomin Li Kaihui Liu Wenlong Wang Xuedong Bai | 2019 | Science China Chemistry2019，62，12： | 2 |

| 16 | Resorptions of 10 mineral elements in leaves of desert shrubs and their contrasting responses to aridity显示文摘Aims We aim to investigate variations in the resorption efficiencies of 10 mineral nutrients[i.e.nitrogen(N),phosphorus(P),potassium(K),magnesium(Mg),calcium(Ca),manganese(Mn),zinc(Zn),alu-minum(Al),iron(Fe)and copper(Cu)]in leaves of desert shrubs and to explore effects of aridity on resorption efficiency of these nutrients.Methods Plant samples were collected from 10 sites in northern Xinjiang Uygur Autonomous Region of China.Samples of green and senesced leaves were analysed to determine concentrations of N,P,K,Mg,Ca,Mn,Zn,Al,Fe and Cu and thus the nutrient resorption efficiency.Important Findings The mean nutrient concentrations in the desert shrubs varied,with the stoichiometric ratio Ca:N(19.3 mg g−1):K(10.5 mg g−1):Mg:P(1.01 mg g−1):Al:Fe:Mn:Zn:Cu(4.78 mg kg−1)=4038:2950:2199:1816:211:37:32:11:2:1 in green leaves;and Ca:N(12.6 mg g−1):Mg:K(7.6 mg g−1):P(0.56 mg g−1):Fe:Al:Mn:Zn:Cu(2.85 mg kg−1)=5583:3710:2943:2523:178:133:119:19:3.7:1 in senesced leaves.Resorption generally occurred for six elements(N,P,K,Cu,Mg and Mn,with average resorption efficiency 47.8%,52.0%,38.6%,41.0%,12.7%and 7.89%,respectively)during leaf senescence,while the other four nutrients tended to accumulate in senesced leaves,showing averagely negative resorption efficiencies[Ca(-3.87%),Al(−57.1%),Zn(−62.6%),Fe(−89.6%)].Aridity showed strikingly different effects on the resorption process of the 10 nutri-ents.Of the four elements with totally(N/P/K)or mostly(Cu)posi-tive observations of resorption efficiency,their resorption generally decreased with aridity,suggesting that drought stress had negative effects on the resorption efficiencies of these elements.In contrast,with at least one-third observations of resorption efficiency being negative,the other elements(Mg/Mn/Ca/Zn/Al/Fe)showed gener-ally increasing resorptive tendency with aridity,except for Zn.This research provided a systematic analysis on the large variation and contrasting responses of the resorption of multi-elements to aridity in typical desert shrubs.Our findings foster the understanding of nutrient resorption patterns of desert plants and enable us to better predict the contrastive effects of drought stress on the cycling of diverse nutrients and the consequent stoichiometric decoupling in plants of desert ecosystems. | Meixia Zhang Yan Luo Zhengbing Yan Jiao Chen Anwar Eziz Kaihui Li Wenxuan Han | 2019 | Journal of Plant Ecology2019，12，2： | 1 |

| 20 | Controlled on-chip fabrication of large-scale perovskite single crystal arrays for high-performance laser and photodetector integration显示文摘Metal halide perovskites possess intriguing optoelectronic properties,however,the lack of precise control of on-chip fabrication of the large-scale perovskite single crystal arrays restricts its application in integrated devices.Here,we report a space confinement and antisolvent-assisted crystallization method for the homogeneous perovskite single crystal arrays spanning 100 square centimeter areas.This method enables precise control over the crystal arrays,including different array shapes and resolutions with less than 10%-pixel position variation,tunable pixel dimensions from 2 to 8 pm as well as the in-plane rotation of each pixel.The crystal pixel could serve as a high-quality whispering gallery mode(WGM)microcavity with a quality factor of 2915 and a threshold of 4.14μJ cm^(-2).Through directly on-chip fabrication on the patterned electrodes,a vertical structured photodetector array is demonstrated with stable photoswitching behavior and the capability to image the input patterns,indicating the potential application in the integrated systems of this method. | Zhangsheng Xu Xun Han Wenqiang Wu Fangtao Li Ru Wang Hui Lu Qiuchun Lu Binghui Ge Ningyan Cheng Xiaoyi Li Guangjie Yao Hao Hong Kaihui Liu Caofeng Pan | 2023 | Light(Science & Applications)2023，12，4： | 0 |
