| 1 | The influence of environment temperatures on single crystalline and polycrystalline silicon solar cell performance显示文摘The influence of the cell temperature (named interior environment temperature) and ambient air temperature (named exterior environment temperature) on the open-circuit voltage,short-circuit current,and output power has been carefully studied for the Si solar cells.The results show that one of the environment temperatures plays the major role,and the temperature dependence of device performance parameters is different for single crystalline and polycrystalline Si solar cells.Furthermore,the ambient air temperature builds a bridge for the comparison of the effect between the cell temperature and the illumination intensity on solar cell performance.Based on the experimental results,the reasons which cause the difference of the environment temperatures dependence are analyzed. | WEN Cai FU Chao TANG JinLong LIU DeXiong HU SiFu XING ZhiGang | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，2： | 6 |
| 2 | Deploying process modeling and attitude control of a satellite with a large deployable antenna显示文摘Modeling and attitude control methods for a satellite with a large deployable antenna are studied in the present paper. Firstly, for reducing the model dimension, three dynamic models for the deploying process are developed, which are built with the methods of multi-rigid-body dynamics, hybrid coordinate and substructure. Then an attitude control method suitable for the deploying process is proposed, which can keep stability under any dynamical parameter variation. Subsequently, this attitude control is optimized to minimize attitude disturbance during the deploying process. The simulation results show that this attitude control method can keep stability and maintain proper attitude variation during the deploying process, which indicates that this attitude control method is suitable for practical applications. | Zhigang Xing Gangtie Zheng | 2014 | Chinese Journal of Aeronautics2014，27，2： | 6 |
| 3 | Additive manufacturing of CNTs/PLA composites and the correlation between microstructure and functional properties显示文摘Owing to the facile,low cost,rapid,personalization characters,3D printing method has been one of the most attractive additive manufacturing processes in medicine,airplane,packaging and printing areas.In this work,a series of carbon nanotubes/polylactic acid(CNTs/PLA) composites were prepared through the combination of molten co-extrusion and 3D printing processes.The orientation and dispersion of CNTs in PLA matrix were investigated to explore the impact of 3D printing process on the morphology of CNTs/PLA composites via transmission electron microscopy,field emission scanning electron microscopy and Raman spectroscopy.X-ray diffractometer,differential scanning calorimetry,and thermal gravity analysis were employed to study the crystal structure and thermal properties of the composites.In addition,the electrical conductivity of the prepared specimen revealed that the orientation of CNTs in PLA might enhance the conductivity of the composite.It was found that 3D printing process was beneficial to increasing the purity of CNTs,electrical conductivity and mechanical properties of CNTs/PLA composites. | Xing Zhou Jingrui Deng Changqing Fang Wanqing Lei Yonghua Song Zisen Zhang Zhigang Huang Yan Li | 2021 | Journal of Materials Science & Technology2021，，1： | 6 |
| 4 | Preparation and Characterization of Waterborne Polyurethane/Cellulose Nanocrystal Composite Membrane from Recycling Waste Paper显示文摘Cellulose plays a key role in abundant organic natural materials meeting the increasing demand for green and biocompatible products.The highly crystalline nanoscale component of cellulose nanocrystals has recently attracted great attention due to the versatile performance as filler or matrix in producing functional materials.In this work,we prepared the waterborne polyurethane via a prepolymer process,and obtained cellulose and cellulose nanocrystals from waste paper via a facile acid hydrolysis process.After that,the cellulose nanocrystals were assembled into film and mixed with polyurethane to prepare flexible polyurethane/cellulose nanocrystals composite membrane with different soaking time.The correlation between the bulk structure and applied properties including thermal resistance and mechanical property was investigated by using Fourier transform infrared spectroscopy(FTIR),X-ray diffraction(XRD),X-ray photoelectron spectroscopy(XPS),scanning electron microscopy(SEM),thermogravimetric analysis(TGA),differential scanning calorimetry(DSC)and folding test.The structure analysis indicates that cellulose nanocrystals prepared from used paper have a quality similar to that of commercial cellulose.Meanwhile,the cellulose nanocrystals have been mixed with polyurethane uniformly.Polyurethane can significantly benefit to the thermal resistance and mechanical property of the cellulose nanocrystals film.The polyurethane/cellulose nanocrystals composite membrane present good flexibility and may hold a significantly potential application as visual and flexible material. | Xing Zhou Xin Zhang Dong Wang Changqing Fang Wanqing Lei Zhigang Huang Yonghua Song Xinyu He Yingwei Huang | 2020 | Journal of Renewable Materials2020，8，6： | 5 |
| 5 | SURFACE METALLIZATION OF CENOSPHERES AND PRECIPITATORS BY ELECTROLESS PLATING显示文摘This paper reports the use of a colloidal Pd0 catalysis system to metallize the surface of precipitators separated from coal fly-ash, and metals such as Cu, Ni etc. are deposited on the precipitators surface. Alternatively, according to the characteristic surface of cenospheres, an Ag coating catalysis system is adopted to first deposit Ag on the cenospheres surface, followed, if necessary, by the deposition of other metals such as Cu, Ni, etc. on the Ag coating to produce monolayer and multilayer metal-coated cenospheres. The surface characteristics and the morphologies of the metal coatings are examined in detail with scanning electron microscopy (SEM), energy dispersive spectroscopy (EDX) and X-ray photoelectron spectroscopy (XPS) techniques. It can be shown that the quality of metal coatings derived from the Ag coating catalysis system, is better than that of the colloidal Pd0 catalysis system. | Chujiang Cai, Zhigang Shen*, Mingzhu Wang, Shulin Ma and Yushan Xing Beijing Key Laboratory for Powder Technology Research and Development, Beijing University of Aeronautics and Astronautics, Beijing 100083, P.

| 7 | Characterization of different-Al-content AlGaN/GaN heterostructures on sapphire显示文摘Al x Ga 1-x N/GaN high-electron-mobility transistor (HEMT) structures with Al composition ranging from x = 0.13 to 0.36 are grown on sapphire substrates by low-pressure metalorganic chemical vapor deposition (LP-MOCVD). The effects of Al content on crystal quality, surface morphology, optical and electrical characteristics of the AlGaN/GaN heterostructures have been analyzed. Although high Al-content (36%) heterostructure exhibits a distinguished photoluminescence peak related to recombination between the two-dimensional electron gas and photoexcited holes (2DEG-h), its crystal quality and rough surface morphology are poor. 2DEG mobility increases with the Al content up to 26% and then it apparently decreases for high Al-content (36%) AlGaN/GaN heterostructure. The increase of sheet carrier density with the increase of Al content has been observed. A high mobility at room temperature of 2105 cm 2 /V s with a sheet carrier density of n s = 1.10 × 10 13 cm -2 , for a 26% Al-content AlGaN/GaN heterostructure has been obtained, which is approaching state-of-the-art for HEMT grown on SiC. Sheet resistance as low as 274 Ω/□ has also been achieved. | DING GuoJian , GUO LiWei, XING ZhiGang, CHEN Yao, XU PeiQiang, JIA HaiQiang, ZHOU JunMing & CHEN Hong Beijing National Laboratory of Condensed Matter Physics, Institute of Physics, Chinese Academy of Sciences, Beijing 100190, China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，1： | 3 |
| 8 | Recent progress in single chip white light-emitting diodes with the InGaN underlying layer显示文摘Tremendous progress has been achieved in white light-emitting diodes (LEDs). To further improve the quality of white light and simplify the fabrication process, a single chip white-light LED with the InGaN underlying layer (UL) was studied and fabricated. The turn-on voltage of this type of LED was 2.7 V, and the spectrum at a forward bias current of 20 mA was comprised of blue (443 nm) and yellow (563 nm) lights. The intensity ratio of blue to yellow light was almost constant with the in- creasing injection current in a certain scope, most important for the solid state illumination. The useful life test showed the light output level remained at a 90% light output level at the driving current of 40 mA after 300 h, meanwhile, the UV and blue LEDs combined with phosphor reached a 20% value after 144 h within 300 h. | WANG XiaoLi, WANG XiaoHui, JIA HaiQiang, XING ZhiGang & CHEN Hong Beijing National Laboratory of Condensed Matter, Institute of Physics, Chinese Academy of Sciences, Beijing 100080, China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，3： | 3 |
| 9 | Design,preparation and measurement of protein/CNTs hybrids:A concise review显示文摘With the development of nanobiotechnology,the carbon nanotubes(CNTs)and protein hybrids system has attracted an increasing attention for great potential application in nanotechnology,medicine,smart materials,light industry,and biology.In this review,the main preparation processes,impact factors,measurement of interactions and potential applications of CNTs/protein are presented from the aspect of experiments.Meanwhile,the proper forces detection methods are illustrated comprehensively to complete the quantitative measurement.Atomic force microscope(AFM)and surface force apparatus(SFA)experiments are described in detail to confirm the powerful function in measuring the interaction forces.In addition,the impact of different protein structures(amino acid residues,αHelix,polypeptide chain,and assembled subunits)on interactions between CNTs and protein is presented and different amino acid residues may intervene largely on interactions.Owing to the relatively little knowledge about the structure,function,and spatial orientation of proteins interaction with CNTs surface,we assume that the key problem is how to prepare CNTs and protein specimen with unique structure(such as the variation of secondary and tridimensional structure of protein or the single CNTs)to investigate the interaction forces instead of the designed,preparation,and detection methods. | Xing Zhou Jian Su Chenxi Wang Changqing Fang Xinyu He Wanqing Lei Chaoqun Zhang Zhigang Huang | 2020 | Journal of Materials Science & Technology2020，42，11： | 3 |
| 10 | Measurement of ^(129)I in ferromanganese crust with AMS显示文摘In the present study,the analytical method for 129iodine(129I) in ferromanganese crusts is developed and129iodine/127iodine(129I/127I) ratio in ferromanganese crusts is measured by the accelerator mass spectrometry(AMS).The developed method is applied to analyze 129I/127 I ratio in two ferromanganese crusts MP5D44 and CXD08-1 collected from the Mid-Pacific Ocean.The results show that 129I/127 I ratio in MP5D44 and CXD08-1crusts varies from 7×10–14 to 1.27×10–12,with the lowest value falling on the detection limit level of AMS reported by previous literatures.For the depth distribution of 129I/127 I,it is found that both MP5D44 and CXD08-1 crusts have two growth generations,and the 129I/127 I profiles in two generations all displayed an approximate exponential decay.According to the 129I/127 I ratio,the generate age of bottom layer of MP5D44 and CXD08-1 was estimated to be 54.77 and 69.69 Ma,respectively. | JI Lihong LIU Guangshan CHEN Zhigang HUANG Yipu XING Na JIANG Shan HE Ming | 2015 | Acta Oceanologica Sinica2015，34，10： | 2 |

| 12 | The distribution of iodine and effects of phosphatization on it in the ferromanganese crusts from the Mid-Pacific Ocean显示文摘In the present paper, iodine(I), iron(Fe), manganese(Mn), cobalt(Co), phosphorus(P) and calcium(Ca)contents in three ferromanganese crusts from the Pacific Ocean are measured by spectrophotometric method and inductively coupled plasma atomic emission spectrometers(ICP-AES) to investigate the contents and distribution of iodine in ferromanganese crusts. The results show that iodine contents in three crusts vary between 27.1 and 836 mg/kg, with an average of 172 mg/kg, and the profile of iodine in the three crusts all exhibits a two-stage distribution zone: a young non-phosphatized zone and an old phosphatized zone that is rich in I, P and Ca. The iodine content ratios of old to young zone in MP5D44, CXD62–1 and CXD08–1 are 2.3, 3.4 and 13.7, respectively.The boundary depths of two-stage zone in MP5D44, CXD62–1 and CXD08–1 locate at 4.0 cm, 2.5 cm and 3.75 cm,respectively, and the time of iodine mutation in three crusts ranges from 17–37 Ma derived from 129 I dating and Co empirical formula, which is consistent with the times of Cenozoic phosphatization events. The present study shows that the intensity of phosphatization is the main responsible for the distribution pattern of iodine in the crusts on the basis of the correlation analysis. Consequently, iodine is a sensitive indicator for phosphatization. | JI Lihong LIU Guangshan HUANG Yipu XING Na CHEN Zhigang | 2015 | Acta Oceanologica Sinica2015，34，8： | 2 |

| 16 | The first two leading modes of the tropical Pacific and their linkage without global warming显示文摘A discrepancy remains in the first two leading empirical orthogonal function(EOF) modes of the tropical Pacific sea surface temperature anomaly(SSTA) based on observations since the 1980s. The EOF1 mode, representing the El Ni?o-Southern Oscillation(ENSO), is a robust result. However, the EOF2 features either El Ni?o Modoki(EM) or ENSO evolution during different periods, which is probably associated with the impacts of global warming. The underlying question is what the EOF2 mode of the tropical Pacific would be without global warming. Using the CMIP5 preindustrial scenario to exclude the influence of global warming, we find that the EOF1 mode of the tropical Pacific SSTA represents ENSO and that the EOF2 mode is not EM. According to the lead–lag correlation between the ENSO and EOF2 modes, the linkage between these two modes is as follows: …El Ni?o → EOF2 → La Ni?a →–EOF2 → El Ni?o…. By analyzing the evolution of sea surface temperature, surface wind, and subsurface ocean temperature anomalies, we find the mechanism linking the ENSO and EOF2 modes is the air–sea interaction associated with the ENSO cycle. This result suggests that the EOF2 mode represents an aspect of ENSO evolution under preindustrial conditions. Therefore, this study further indicates that the EM is probably due to the influence of global warming. | Yang Li QuanLiang Chen XiaoRan Liu Nan Xing ZhiGang Cheng HongKe Cai Xin Zhou Dong Chen XiaoFei Wu MingGang Li | 2019 | Earth and Planetary Physics2019，3，2： | 1 |
| 17 | IRE1-RACK1 axis orchestrates ER stress preconditioning-elicited cytoprotection from ischemia/reperfusion injury in liver显示文摘Endoplasmic reticulum(ER)stress is involved in ischemic preconditioning that protects various organs from ischemia/reperfusion(I/R)injury.We established an in vivo ER stress preconditioning model in which tunicamycin was injected into rats before hepatic I/R.The hepatic I/R injury,demonstrated by serum aminotransferase level and the ultra-structure of the liver,was alleviated by administration of tunicamycin,which induced ER stress in rat liver by activating inositol-requiring enzyme1(IRE1)andupregulating78 kDaglucose-regulated protein(GRP78).The proteomic identification for IRE1 binders revealed interaction and cooperation among receptor for activated C kinase 1(RACK1),phosphorylated AMPK,and IRE1 under ER stress conditions in a spatiotemporal manner.Furthermore,in vitro ER stress preconditioningwas induced by thapsigargin and tunicamycin in L02 and Hep G2 cells.Surprisingly,BCL2 was found to bephosphorylated by IRE1 under ER stress conditions to prevent apoptotic process by activation of autophagy.In conclusion,ER stress preconditioning protects against hepatic I/R injury,which is orchestrated by IRE1-RACK1 axis through the activation of BCL2.Our findings provide novel insights into the molecular pathways underlying ER stress preconditioning-elicited cytoprotective effect against hepatic I/R injury. | Dong Liu Xing Liu Ti Zhou William Yao Jun Zhao Zhigang Zheng Wei Jiang Fengsong Wang Felix O.Aikhionbare Donald L.Hill Nerimah Emmett Zhen Guo Dongmei Wang Xuebiao Yao Yong Chen | 2016 | Journal of Molecular Cell Biology2016，8，2： | 1 |
| 18 | The First High-quality Reference Genome of Sika Deer Provides Insights into High-tannin Adaptation显示文摘Sika deer are known to prefer oak leaves,which are rich in tannins and toxic to most mammals;however,the genetic mechanisms underlying their unique ability to adapt to living in the jungle are still unclear.In identifying the mechanism responsible for the tolerance of a highly toxic diet,we have made a major advancement by explaining the genome of sika deer.We generated the first high-quality,chromosome-level genome assembly of sika deer and measured the correlation between tannin intake and RNA expression in 15 tissues through 180 experiments.Comparative genome analyses showed that the UGT and CYP gene families are functionally involved in the adaptation of sika deer to high-tannin food,especially the expansion of the UGT family 2 subfamily B of UGT genes.The first chromosome-level assembly and genetic characterization of the tolerance to a highly toxic diet suggest that the sika deer genome may serve as an essential resource for understanding evolutionary events and tannin adaptation.Our study provides a paradigm of comparative expressive genomics that can be applied to the study of unique biological features in non-model animals. | Xiumei Xing Cheng Ai Tianjiao Wang Yang Li Huitao Liu Pengfei Hu Guiwu Wang Huamiao Liu Hongliang Wang Ranran Zhang Junjun Zheng Xiaobo Wang Lei Wang Yuxiao Chang Qian Qian Jinghua Yu Lixin Tang Shigang Wu Xiujuan Shao Alun Li Peng Cui Wei Zhan Sheng Zhao Zhichao Wu Xiqun Shao Yimeng Dong Min Rong Yihong Tan Xuezhe Cui Shuzhuo Chang Xingchao Song Tongao Yang Limin Sun Yan Ju Pei Zhao Huanhuan Fan Ying Liu Xinhui Wang Wanyun Yang Min Yang Tao Wei Shanshan Song Jiaping Xu Zhigang Yue Qiqi Liang Chunyi Li Jue Ruan Fuhe Yang | 2023 | Genomics, Proteomics & Bioinformatics2023，21，1： | 1 |
| 19 | Permian Radiolarians from the A'nyemaqen Mélange Zone in the Huashixia Area of Madoi County,Qinghai Province,Western China,and Their Implications on Regional Tectonism显示文摘The Huashixia area in the Madoi County, Qinghai Province, western China is one of the most important areas for the studies of the formation and evolution of the A'nyemaqen mélange zone due to the well exposed, relatively complete tectonostratigraphic successions. However, the timing and evolutionary process of the A'nyemaqen paleo-ocean has long been poorly understood. Recently, we obtained abundant radiolarians from the siliceous rocks of the Maerzheng Formation of this mélange zone in Huashixia. Total 19 species in 10 radiolarian genera have been identified. They belong mainly to the Albaillellaria, Spumellaria, Entactinaria, and Latentifistularia. Four radiolarian assemblage zones are established, including: the Pseudoalbaillella rhombothoracata, Pseudoalbaillella scalprata, Ruzhencevispongus uralicus, and Follicucullus bipartitus-Follicucullus sp. cf. F. ventricosus zones. Radiolarian faunal correlations suggest a late Artinskian–early Kungurian age and late Capitanian–early Wuchiapingian age for the first two zones from the lower part and the last two zones from the upper parts of the Maerzheng Formation, respectively. All radiolarians are typical of deep water elements living in deep oceans in low latitudes during the Permian. Previously, the radiolarians of Early Carboniferous to Early Permian age and fusulinids of Early–Middle Permian age have also been reported from the A'nyemaqen mélange successions. The combination of the newly found radiolarians with the previously reported faunal and microfloral assemblages as well as radiometric ages obtained from the same stratigraphic units indicates that the A'nyemaqen paleo-ocean may have opened initially during the Early Carboniferous, expanded from the Early–Middle Permian, reached its acme in the early Late Permian, shrunk during the latest Permian to Early Triassic, and eventually was closed in the Middle Triassic. | Zhigang Zhao Xing Huang Xionghua Zhang Bing Yang Zhong-Qiang Chen Fuhao Xiong | 2016 | Journal of Earth Science2016，27，4： | 1 |
