1Aerosol and boundary-layer interactions and impact on air quality显示文摘Air quality is concerned with pollutants in both the gas phase and solid or liquid phases. The latter are referred to as aerosols, which are multifaceted agents affecting air quality, weather and climate through many mechanisms. Unlike gas pollutants, aerosols interact strongly with meteorological variables with the strongest interactions taking place in the planetary boundary layer(PBL). The PBL hosting the bulk of aerosols in the lower atmosphere is affected by aerosol radiative effects. Both aerosol scattering and absorption reduce the amount of solar radiation reaching the ground and thus reduce the sensible heat fluxes that drive the diurnal evolution of the PBL. Moreover, aerosols can increase atmospheric stability by inducing a temperature inversion as a result of both scattering and absorption of solar radiation, which suppresses dispersion of pollutants and leads to further increases in aerosol concentration in the lower PBL.Such positive feedback is especially strong during severe pollution events. Knowledge of the PBL is thus crucial for understanding the interactions between air pollution and meteorology. A key question is how the diurnal evolution of the PBL interacts with aerosols, especially in vertical directions, and affects air quality.We review the major advances in aerosol measurements, PBL processes and their interactions with each other through complex feedback mechanisms, and highlight the priorities for future studies.Zhanqing Li Jianping Guo Aijun Ding Hong Liao Jianjun Liu Yele Sun Tijian Wang Huiwen Xue Hongsheng Zhang Bin Zhu 2017National Science Review2017,4,6:37

3Performing optical logic operations by a diffractive neural network显示文摘Optical logic operations lie at the heart of optical computing,and they enable many applications such as ultrahighspeed information processing.However,the reported optical logic gates rely heavily on the precise control of input light signals,including their phase difference,polarization,and intensity and the size of the incident beams.Due to the complexity and difficulty in these precise controls,the two output optical logic states may suffer from an inherent instability and a low contrast ratio of intensity.Moreover,the miniaturization of optical logic gates becomes difficult if the extra bulky apparatus for these controls is considered.As such,it is desirable to get rid of these complicated controls and to achieve full logic functionality in a compact photonic system.Such a goal remains challenging.Here,we introduce a simple yet universal design strategy,capable of using plane waves as the incident signal,to perform optical logic operations via a diffractive neural network.Physically,the incident plane wave is first spatially encoded by a specific logic operation at the input layer and further decoded through the hidden layers,namely,a compound Huygens’metasurface.That is,the judiciously designed metasurface scatters the encoded light into one of two small designated areas at the output layer,which provides the information of output logic states.Importantly,after training of the diffractive neural network,all seven basic types of optical logic operations can be realized by the same metasurface.As a conceptual illustration,three logic operations(NOT,OR,and AND)are experimentally demonstrated at microwave frequencies.Chao Qian Xiao Lin Xiaobin Lin Jian Xu Yang Sun Erping Li Baile Zhang Hongsheng Chen 2020Light(Science & Applications)2020,9,1:8
4A fundamental theorem for eco-environmental surface modelling and its applications显示文摘We propose a fundamental theorem for eco-environmental surface modelling(FTEEM) in order to apply it into the fields of ecology and environmental science more easily after the fundamental theorem for Earth’s surface system modeling(FTESM). The Beijing-Tianjin-Hebei(BTH) region is taken as a case area to conduct empirical studies of algorithms for spatial upscaling, spatial downscaling, spatial interpolation, data fusion and model-data assimilation, which are based on high accuracy surface modelling(HASM), corresponding with corollaries of FTEEM. The case studies demonstrate how eco-environmental surface modelling is substantially improved when both extrinsic and intrinsic information are used along with an appropriate method of HASM. Compared with classic algorithms, the HASM-based algorithm for spatial upscaling reduced the root-meansquare error of the BTH elevation surface by 9 m. The HASM-based algorithm for spatial downscaling reduced the relative error of future scenarios of annual mean temperature by 16%. The HASM-based algorithm for spatial interpolation reduced the relative error of change trend of annual mean precipitation by 0.2%. The HASM-based algorithm for data fusion reduced the relative error of change trend of annual mean temperature by 70%. The HASM-based algorithm for model-data assimilation reduced the relative error of carbon stocks by 40%. We propose five theoretical challenges and three application problems of HASM that need to be addressed to improve FTEEM.Tianxiang YUE Na ZHAO Yu LIU Yifu WANG Bin ZHANG Zhengping DU Zemeng FAN Wenjiao SHI Chuanfa CHEN Mingwei ZHAO Dunjiang SONG Shihai WANG Yinjun SONG Changqing YAN Qiquan LI Xiaofang SUN Lili ZHANG Yongzhong TIAN Wei WANG Ying’an WANG Shengnan MA Hongsheng HUANG Yimin LU Qing WANG Chenliang WANG Yuzhu WANG Ming LU Wei ZHOU Yi LIU Xiaozhe YIN Zong WANG Zhengyi BAO Miaomiao ZHAO Yapeng ZHAO Yimeng JIAO Ufra NASEER Bin FAN Saibo LI Yang YANG John PWILSON 2020Science China Earth Sciences2020,63,8:7

6A cross-linked polyacrylamide electrolyte with high ionic conductivity for compressible supercapacitors with wide temperature tolerance显示文摘The development of compressible supercapacitors (SCs) that is tolerant to wide temperature range has been severely hindered due to the poor ionic conductivity and absence of extra functions in conventional polymer electrolytes.Herein,a highly conductive and compressible hydrogel polyelectrolyte has been prepared from polyacrylamide cross-linked by methacrylated graphene oxide (MGO-PAM) and the polyelectrolyte can maintain its excellent elasticity at-30 ℃ as well as its original shape at 100 ℃.As a result,the SC based on the MGO-PAM polyelectrolyte outperformed those fabricated with the conventional poly(vinyl alcohol)(PVA)/H2SO4 electrolyte over a wide temperature window between-30 and 100 ℃.Meanwhile,the device shows an excellent cycling stability (capacitance retention of 93.3% after 8,000 cycles at-30 ℃ and 76.5 % after 4,000 cycles under 100 ℃) and a reversible compressibility (a high capacitance retention of 94.1% under 80% compression).Therefore,the MGO-PAM polyelectrolyte enables the fabrication of compressible SCs with a wide operating temperature,rendering new insights for developing next-generation robust and multifunctional energy-storage devices.Xuting Jin Guoqiang Sun Guofeng Zhang Hongsheng Yang Yukun Xiao Jian Gao Zhipan Zhang Liangti Qu 2019Nano Research2019,12,5:4
7A super pan-genomic landscape of rice显示文摘Pan-genomes from large natural populations can capture genetic diversity and reveal genomic complexity.Using de novo longread assembly,we generated a graph-based super pan-genome of rice consisting of a 251-accession panel comprising both cultivated and wild species of Asian and African rice.Our pan-genome reveals extensive structural variations(SVs)and gene presence/absence variations.Additionally,our pan-genome enables the accurate identification of nucleotide-binding leucine-rich repeat genes and characterization of their inter-and intraspecific diversity.Moreover,we uncovered grain weight-associated SVs which specify traits by affecting the expression of their nearby genes.We characterized genetic variants associated with submergence tolerance,seed shattering and plant architecture and found independent selection for a common set of genes that drove adaptation and domestication in Asian and African rice.This super pan-genome facilitates pinpointing of lineage-specific haplotypes for trait-associated genes and provides insights into the evolutionary events that have shaped the genomic architecture of various rice species.Lianguang Shang Xiaoxia Li Huiying He Qiaoling Yuan Yanni Song Zhaoran Wei Hai Lin Min Hu Fengli Zhao Chao Zhang Yuhua Li Hongsheng Gao Tianyi Wang Xiangpei Liu Hong Zhang Ya Zhang Shuaimin Cao Xiaoman Yu Bintao Zhang Yong Zhang Yiqing Tan Mao Qin Cheng Ai Yingxue Yang Bin Zhang Zhiqiang Hu Hongru Wang Yang Lv Yuexing Wang Jie Ma Quan Wang Hongwei Lu Zhe Wu Shanlin Liu Zongyi Sun Hongliang Zhang Longbiao Guo Zichao Li Yongfeng Zhou Jiayang Li Zuofeng Zhu Guosheng Xiong Jue Ruan Qian Qian 2022Cell Research2022,32,10:3

9Comparison of pigment composition and melanin content among white,light-green,dark-green,and purple morphs of sea cucumber,Apostichopus japonicus显示文摘Sea cucumber, Apostichopus japonicus(Selenka), is a commercially important marine species in China. Among the differently colored varieties sold in China, white and purple sea cucumbers have the greatest appeal to consumers. Identification of the pigments that may contribute to the formation of different color morphs of sea cucumbers will provide a scientific basis for improving the cultivability of desirable color morphs. In this study,sea cucumbers were divided into four categories according to their body color: white, light green, dark green, and purple. The pigment composition and contents in the four groups were analyzed by high performance liquid chromatography(HPLC). The results show that the pigment contents differed significantly among the white, lightgreen, dark-green, and purple sea cucumbers, and there were fewer types of pigments in white sea cucumber than in the other color morphs. The only pigments detected in white sea cucumbers were guanine and pteroic acid.Guanine and pteroic acid are structural colors, and they were also detected in light-green, dark-green, and purple sea cucumbers. Every pigment detected, except for pteroic acid, was present at a higher concentration in purple morphs than in the other color morphs. The biological color pigments melanin, astaxanthin, β-carotene, and lutein were detected in light-green, dark-green, and purple sea cucumbers. While progesterone and lycopene,which are also biological color pigments, were not detected in any of the color morphs. Melanin was the major pigment contributing to body color, and its concentration increased with deepening color of the sea cucumber body. Transmission electron microscopy analyses revealed that white sea cucumbers had the fewest epidermal melanocytes in the body wall, and their melanocytes contained fewer melanosomes as well as non-pigmented pre-melanosomes. Sea cucumbers with deeper body colors contained more melanin granules. In the body wall of dark-green and purple sea cucumbers, melanin granules were secreted out of the cell. The results of this study provide evidence for the main factors responsible for differences in coloration among white, light-green, darkgreen, and purple sea cucumbers, and also provide the foundation for further research on the formation of body color in sea cucumber, A. japonicus.XING Lili SUN Lina LIU Shilin LI Xiaoni MIAO Ting ZHANG Libin YANG Hongsheng 2017Acta Oceanologica Sinica2017,36,12:3
10Methane coupling in microwave plasma under atmospheric pressure显示文摘Methane coupling in microwave plasma under atmospheric pressure has been investigated.The effects of molar ratio n(CH4)/n(H2),flow rate and microwave power on the reaction have been studied.(1)With the decrease of n(CH4)/n(H2)ratio,methane conversion,C2 hydrocarbon yield,energy yield and space-time yield of acetylene increased,but the yield of carbon deposit decreased.(2)With the increase of microwave power,energy yield of acetylene decreased,but space-time yield of acetylene increased.(3)With the increase of flow rate,energy yield and space-time yield of acetylene increased first and then decreased.Finally,under the reaction conditions of CH4 flow rate of 700 mL/min,n(CH4)/n(H2)ratio of 1/4 and microwave power of 400 W,the energy yield and space-time yield of acetylene could reach 0.337 mmol/kJ and 12.3 mol/(s m3),respectively.The reaction mechanism of methane coupling in microwave plasma has been investigated based on the thermodynamics of chemical reaction.Interestingly,the acetylene yield of methane coupling in microwave plasma was much higher than the maximum thermodynamic yield of acetylene.This phenomenon was tentatively explained from non-expansion work in the microwave plasma system.Changsheng Shen Dekun Sun Hongsheng Yang 2011Journal of Natural Gas Chemistry2011,20,4:2

15Comparative analysis of transcriptomes from albino and control sea cucumbers, Apostichopus japonicus显示文摘The sea cucumber Apostichopus japonicus is an important economic species in China. Its dorsal body wall color is commonly tawny, whereas its ventral surface is fawn. Albino sea cucumbers are rarely observed. In order to profile gene expression and screen albinism-related genes, we compared the transcriptome of albino samples with a control by 454 cDNA sequencing. We found that 6 539 identified genes on the basis of sequence similarity to known genes were expressed in the albino A. japonicus. The gene ontology analysis indicated that the transcription of genes associated with the terms of biological regulation and pigmentation was non-abundant in the albino library compared to the control. Based on an analysis using the Kyoto Encyclopedia of Genes and Genomics(KEGG) database, we identified 14 important genes that were involved in major intercellular signaling pathways related to melanin synthesis, such as tyrosine metabolism, the mitogen-activated protein kinase(MAPK) pathway, and melanogenesis. The expressions of fibroblast growth factor receptor 4(FGFR4), protein kinase C(PKC), protein kinase A(PKA), and Ras genes were significantly down-regulated in the albino transcriptome compared with the control, while the expressions of homogentisate 1, 2-dioxygenase gene(HGO), cAMP-responsive element binding protein(CREB), transcription factor AP-1(c-jun), and calmodulin(CaM) were significantly up-regulated(Fisher's exact test, p < 0.05). These differentially expressed genes could be candidate genes for revealing the mechanism of albinism and investigating regulation of melanin synthesis in A. japonicus.MA Deyou YANG Hongsheng SUN Lina XU Dongxue 2014Acta Oceanologica Sinica2014,33,8:1
