| 1 | A draft sequence of the rice (Oryza sativa ssp. indica) genome显示文摘The sequence of the rice genome holds fundamental information for its biology, including physiology, genetics, development, and evolution, as well as information on many beneficial phenotypes of economic significance. Using a 'whole genome shotgun' approach, we have pro-duced a draft rice genome sequence of Oryza sativa ssp. in-dica, the major crop rice subspecies in China and many other regions of Asia. The draft genome sequence is constructed from over 4.3 million successful sequencing traces with an accumulative total length of 2214.9 Mb. The initial assembly of the non-redundant sequences reached 409.76 Mb in length, based on 3.30 million successful sequencing traces with a total length of 1797.4 Mb from an indica variant cultivar 93-11, giving an estimated coverage of 95.29% of the rice genome with an average base accuracy of higher than 99%.

| 2 | Increasingπ-electron availability in benzene ring incorporated graphitic carbon nitride for increased photocatalytic hydrogen generation显示文摘Increasing the availability ofπ-electron in graphitic carbon nitride(g-C_(3)N_(4))can reduce the band gap and thus enhance the photocatalytic hydrogen(H_(2))generation activity upon exposure to visible light,However,such strategy has not yet been largely applied to increase the H_(2)generation of g-C_(3)N_(4).Herein,we succes s fully increased the amount ofπ-electron in g-C_(3)N_(4)by incorporatingπ-electron-rich benzene rings through copolymerization of melamine and trimesic acid in air.The incorporation of benzene rings not only extends the light absorption of g-C_(3)N_(4)to 650 nm,but also improves the electrical conductivity due to delocalization ofπelectrons in benzene rings.As a result,a 3.4 times enhancement of photocatalytic H_(2)generation was achieved from the g-C_(3)N_(4)with benzene ring incorporation in comparing with that of pristine g-C_(3)N_(4).More interestingly,H_(2)generation still occurs under irradiation of the light ofλ≥490 nm,above the absorption edge of pristine g-C_(3)N_(4)(~460 nm),illustrating the positive effectiveness of incorporated benzene rings on enhancing the H_(2)generation capacity of g-C_(3)N_(4).The present work manifests the advantages of increasingπ-conjugated electrons on designing highly active g-C_(3)N_(4)photocatalysts. | Xiangang Lin Xiaojuan Hou Lixia Cui Shiqiang Zhao Hong Bi Haiwei Du Yupeng Yuan | 2021 | Journal of Materials Science & Technology2021，，6： | 2 |
| 3 | Plasmonic evolution of atomically size-selected Au clusters by electron energy loss spectrum显示文摘The plasmonic response of gold clusters with atom number(N)=100–70000 was investigated using scanning transmission electron microscopy-electron energy loss spectroscopy.For decreasing N,the bulk plasmon remains unchanged above N=887 but then disappears,while the surface plasmon firstly redshifts from 2.4 to 2.3 e V above N=887 before blueshifting towards 2.6 e V down to N=300,and finally splitting into three fine features.The surface plasmon’s excitation ratio is found to follow N^(0.669),which is essentially R^(2).An atomically precise evolution picture of plasmon physics is thus demonstrated according to three regimes:classical plasmon(N=887–70000),quantum confinement corrected plasmon(N=300–887)and molecule related plasmon(N<300). | Siqi Lu Lin Xie Kang Lai Runkun Chen Lu Cao Kuojuei Hu Xuefeng Wang Jinsen Han Xiangang Wan Jianguo Wan Qing Dai Fengqi Song Jiaqing He Jiayu Dai Jianing Chen Zhenlin Wang Guanghou Wang | 2021 | National Science Review2021，8，12： | 0 |
| 4 | Microwave awakening the n-π^(*) electronic transition in highly crystalline polymeric carbon nitride nanosheets for photocatalytic hydrogen generation显示文摘The n-π^(*) electronic transition in polymeric carbon nitride(PCN)can remarkably harvest visible light,which thus potentially promotes the photocatalytic hydrogen H2 generation.However,awaking the n-π^(*) lectronic transition has proven to be a grand challenge.Herein,we reported on the awakening of n-π^(*) electronic transition by microwave thermolysis of urea pellet,which yielded the PCN with absorption edge of 600 nm,near 140 nm red-shift from 460 nm of pristine PCN.The n-π^(*) electronic transition endows PCN with an increased photocata lytic H_(2) generation,with a highest H_(2) rate of 61.7μmol h^(-1) under visible light exposure,which is near 6 times higher than that by using the PCN from the thermolysis of urea pellets in an electric furnace(10.6μmol h^(-1)).Furthermore,the n-π^(*) transition in PCN leads to the longest wavelength of 535 nm that can initiate H2 generation,remarkably longer than the absorption edge of pristine PCN(460 nm).This work manifests the advantages of microwave sintering route to awaken the n-π^(*) electronic transition in PCN for an increased photocata lytic performance. | Xiangang Lin Haiwei Du Daochuan Jiang Peng Zhang Zhiwu Yu Hong Bi Yupeng Yuan | 2022 | Journal of Energy Chemistry2022，31，2： | 0 |
