| 1 | Effect of polycarboxylate-type superplasticizer on the paste fluidity based on the water film thickness of flocs显示文摘The excess water film theory and the properties of flocs are integrated to examine the effect of the polycarboxylate-type superplasticizer on the paste fluidity.The theory states that excess water can surround the flocs rather than the particles and that the cell consists of a floc and a superficial water film.Experiments on limestone powder pastes were conducted to verify the theory.The superplasticizer dosage(sp%)and the water–powder ratio by volume(Vw/Vp)were systematically varied.A sedimentation balance method was used to measure the size distribution of the flocs in the limestone powder pastes.The water film thickness(WFT)of flocs was then calculated and shown to determine the paste fluidity.Based on this WFT of flocs,the effect of the sp on the paste fluidity was determined and then compared with the effect of water. | WU Qiong AN XueHui LIU ChunNa | 2014 | Science China(Technological Sciences)2014，57，8： | 7 |

| 3 | A Hu sheep genome with the first ovine Y chromosome reveal introgression history after sheep domestication显示文摘The Y chromosome plays key roles in male fertility and reflects the evolutionary history of paternal lineages.Here,we present a de novo genome assembly of the Hu sheep with the first draft assembly of ovine Y chromosome(o MSY),using nanopore sequencing and Hi-C technologies.The o MSY that we generated spans 10.6 Mb from which 775 Y-SNPs were identified by applying a large panel of whole genome sequences from worldwide sheep and wild Iranian mouflons.Three major paternal lineages(HY1a,HY1b and HY2)were defined across domestic sheep,of which HY2 was newly detected.Surprisingly,HY2 forms a monophyletic clade with the Iranian mouflons and is highly divergent from both HY1a and HY1b.Demographic analysis of Y chromosomes,mitochondrial and nuclear genomes confirmed that HY2 and the maternal counterpart of lineage C represented a distinct wild mouflon population in Iran that diverge from the direct ancestor of domestic sheep,the wild mouflons in Southeastern Anatolia.Our results suggest that wild Iranian mouflons had introgressed into domestic sheep and thereby introduced this Iranian mouflon specific lineage carrying HY2 to both East Asian and Africa sheep populations. | Ran Li Peng Yang Ming Li Wenwen Fang Xiangpeng Yue Hojjat Asadollahpour Nanaei Shangquan Gan Duo Du Yudong Cai Xuelei Dai Qimeng Yang Chunna Cao Weidong Deng Sangang He Wenrong Li Runlin Ma Mingjun Liu Yu Jiang | 2021 | Science China(Life Sciences)2021，64，7： | 1 |

| 5 | Modulation of morphology and electronic structure on MoS_(2)-based electrocatalysts for water splitting显示文摘Electrocatalytic water splitting into hydrogen is one of the most favorable approaches to produce renewable energy.MoS_(2)has received great research attention for both hydrogen evolution reaction(HER)and oxygen evolution reaction(OER)due to its unique structure and ability to be chemically modified,enabling its electrocatalytic activity to be further enhanced or made comparable to that of Pt-based materials.In this review,we discuss the important fabrication approaches of MoS_(2)ultrathin nanosheet(MoS_(2)NS)to improve the intrinsic catalytic activity of bulk MoS_(2).Moreover,several modification strategies involve either morphology modulation or electron structural modulation to improve the charge transfer kinetics,including doping,vacancy,and heterojunction construction or single-atom anchor.Our perspectives on the key challenges and future directions of developing high-performance MoS_(2)-based electrocatalysts for overall water splitting are also discussed. | Mengmeng Liu Chunyan Zhang Ali Han Ling Wang Yujia Sun Chunna Zhu Rui Li Sheng Ye | 2022 | Nano Research2022，15，8： | 1 |
| 6 | Polymorphism analysis and supertype definition of swine leukocyte antigen class I molecules in three-way crossbred(Landrace,Duroc,and Yorkshire)pigs:implications for the vaccine development of African swine fever virus显示文摘Dear Editor,Swine major histocompatibility complex(MHC)is a highly polymorphic gene in pigs and is also called swine leukocyte antigen(SLA)(Fan et al.,2018).SLA is divided into three major categories,SLA I(SLA-1,-2,-3),SLA II,and SLA III(Smith et al.,2005).SLA I plays an important role in cellular immunity which can eliminate viruses and other foreign antigens in pigs(Macdonald et al.,2010).SLA-1,SLA-2 and SLA-3 are important SLA I alleles and are highly polymorphic.Polymorphism causes extreme difficulties in screening broadly protective cytotoxic lymphocyte(CTL)epitope antigens.The supertype which is built based on peptide-binding specificity of each SLA I can overcome this difficulty to some extent(Thomsen et al.,2013). | Limin Ba Zhenbao Wang William J Liu Dongxun Wu Wangzhen Xiang Peng Qi Chunna Dong Yanxin Hu Ping Lu Jin Xiao Changyuan Yu | 2020 | Science China(Life Sciences)2020，63，10： | 0 |
| 7 | A comprehensive review on semiconductor-based photocatalysts toward the degradation of persistent pesticides显示文摘Pesticides refer to the chemicals to regulate plant growth and control pests used in agriculture.However,the extensive use of pesticides causes serious pollution that threatens the ecological environment and human health.Photocatalytic degradation of pesticides has become a promising way to deal with pesticide pollution.In this review,pesticides are classified according to the different targets and chemical structures.The recent developments on semiconductor-based photocatalysts including metal oxides,metal oxyhalides,carbon nitrides,metal sulfides were reviewed for degradation of pesticides.Importantly,several modification strategies to improve the photocatalytic performance are described such as doping,heterojunction construction,defect engineering,with special emphasis on anchoring single atom catalyst.Moreover,extensive efforts should be made to indepth understand the photodegradation mechanism by monitoring key intermediates.Our perspectives on the key challenges and future directions of developing high-performance semiconductor-based photocatalysts for pesticide degradation are elaborated. | Jing Zhu Min Liao Chen Zhao Mengmeng Liu Ali Han Chunna Zhu Yujia Sun Meng Zhao Sheng Ye Haiqun Cao | 2023 | Nano Research2023，16，5： | 0 |
