| 1 | Two gap-free reference genomes and a global view of the centromere architecture in rice显示文摘Rice(Oryza sativa),a major staple throughout the world and a model system for plant genomics and breeding,was the first crop genome sequenced almost two decades ago.However,reference genomes for all higher organisms to date contain gaps and missing sequences.Here,we report the assembly and analysis of gap-free reference genome sequences for two elite O.sativa xian/indica rice varieties,Zhenshan 97 and Minghui 63,which are being used as a model system for studying heterosis and yield.Gap-free reference genomes provide the opportunity for a global view of the structure and function of centromeres.We show that all rice centromeric regions share conserved centromere-specific satellite motifs with different copy numbers and structures.In addition,the similarity of CentO repeats in the same chromosome is higher than across chromosomes,supporting a model of local expansion and homogenization.Both genomes have over 395 non-TE genes located in centromere regions,of which∼41%are actively transcribed.Two large structural variants at the end of chromosome 11 affect the copy number of resistance genes between the two genomes.The availability of the two gap-free genomes lays a solid foundation for further understanding genome structure and function in plants and breeding climate-resilient varieties. | Jia-Ming Song Wen-Zhao Xie Shuo Wang Yi-Xiong Guo Dal-Hoe Koo Dave Kudrna Chenbo Gong Yicheng Huang Jia-Wu Feng Wenhui Zhang Yong Zhou Andrea Zuccolo Evan Long Seunghee Lee Jayson Talag Run Zhou Xi-Tong Zhu Daojun Yuan Joshua Udall Weibo Xie Rod AWing Qifa Zhang Jesse Poland Jianwei Zhang Ling-Ling Chen | 2021 | Molecular Plant2021，14，10： | 9 |

| 4 | Photoinduced small electron polarons generation and recombination in hematite显示文摘Polarons generally affect adversely the photochemical and photophysical properties of transition metal oxides.However,the excited-state dynamics of polarons are not fully established to date and thus require an atomistic understanding.We focus onα-Fe_(2)O_(3)with photoexcitation,electron injection,and heterovalent doping as the small polaron models,and conduct simulations of ab initio adiabatic molecular dynamics(AIMD)and nonadiabatic molecular dynamics(NA-MD).The elaborately designed AIMD simulations show that localization of electron at a single Fe site is an adiabatic and ultrafast process within sub-15 fs.Fe_(2)O_(3)doping with an electron or a Si and Ti dopant forms a localized electron polaron while photoexcitation forms localized electron and hole polarons simultaneously,leading to diverse electron–hole recombination dynamics.NA-MD simulations demonstrate that recombination of an electron polaron created by doping with a delocalized hole at the valence band maximum ofα-Fe_(2)O_(3)takes place around 5 ps,while recombination between a pair of small electron and hole polarons in photoexcited Fe_(2)O_(3)delays to about 110 ps owing to weak NA coupling and fast decoherence process.The ultrafast formation of small electron polarons inα-Fe_(2)O_(3)impedes the accumulation of delocalized holes in the valence band that directly participate in water oxidation at photoanodes.The detrimental effect can be partially circumvented in photoexcited Fe_(2)O_(3)for slowing electron–hole recombination despite polarons may retain low charge mobility.These findings provide a fundamental understanding of the excited-state dynamics of small electron polaron inα-Fe_(2)O_(3)and may help design efficient transition metal oxides photoanodes. | Cheng Cheng Yonghao Zhu Zhaohui Zhou Run Long Wei-Hai Fang | 2022 | npj Computational Materials2022，，1： | 1 |

| 6 | Research status and development of extraction process of zinc-bearing dust from ironmaking and steelmaking—a critical review显示文摘Almost 29.57–38.46 million tons of zinc-bearing dust were produced in Chinese iron and steel enterprises annually.The recovery of Zn and other metals in zinc-bearing dust from ironmaking and steelmaking could improve economic efficiency.However,zinc-bearing dust was classified as hazardous waste,and the volatile metals(like Zn,Na,Pb,etc.)in zinc-bearing dust limited the direct reusing in a blast furnace.Therefore,the formation process,fundamental characteristics,and current extraction process of Zn from zinc-bearing dust,associated with thermodynamics and kinetics of the pyrometallurgical process,hydrometallurgical process,and pyro-hydrometallurgical process,were analyzed.It is indicated that industrialized pyrometallurgical processes are undergoing high energy consumption and pollution such as rotary kiln and rotary hearth furnace process.The vacuum carbothermal reduction process can realize low carbon emission and no waste produced in the process.The hydrometallurgical leaching processes in strong acid,strong alkali,and ammonium solutions result in serious liquid pollution and equipment corrosion.The pyrometallurgical process involves complex kinetics and lacks kinetic research on semi-industrialization and industrialization.Water-soluble components in zinc-bearing dust can be removed by water leaching.The kinetics of the strong acid leaching is mainly controlled by the leaching kinetics of Fe_(2)O_(3) and ZnFe_(2)O_(4),while the alkali leaching and weak acid leaching are controlled by the kinetics of ZnO leaching.Zn in the zincbearing dust can be extracted by a low-temperature sodium roasting–weak acid leaching process that reduces equipment corrosion and environmental pollution. | Ren-lin Zhu Run Huang An-xun Xu Bo Li Yong-gang Zang Xue Deng Jing Yang Miao Li Xian-ze Long | 2023 | Journal of Iron and Steel Research(International)2023，30，7： | 1 |

| 8 | Special issue on resources recycling of solid wastes from ironmaking and steelmaking显示文摘Driven by the double carbon policy,the iron and steel industry urgently needs to implement a new development concept to strengthen the use of solid waste resources from ironmaking and steelmaking and effectively enhance the economic benefits of recycling resources in order to reduce the accumulation of solid waste resources in the iron and steel industry.The iron and steel production process produces more than 600 million tons of solid waste annually,including metallurgical dust sludge,blast furnace slag and steel slag,etc.From the perspective of environmental friendliness,the efficient utilization of ironmaking and steelmaking solid waste resources through innovative cross-industry technologies is of great significance to the low-carbon,green and high-quality development goals of the iron and steel industry. | Xue-wei Lv Hong-ming Long Run Huang | 2023 | Journal of Iron and Steel Research(International)2023，30，7： | 0 |
| 9 | Efficient passivation of DY center in CH_(3)NH_(3)PbBr_(3) by chlorine:Quantum molecular dynamics显示文摘MAPbBr_(3)(MA=CH_(3)NH_(3)^(+))doping with bismuth increases electric conductivity,charge carrier density and photostability,reduces toxicity,and expands light absorption.However,Bi doping shortens excited-state lifetimes due to formation of DY−charge recombination centers.Using nonadiabatic molecular dynamics and time-domain density functional theory,we demonstrate that the DY−center forms a deep,highly localized hole trap,which accelerates nonradiative relaxation ten-fold and is responsible for 90%of carrier losses.Hole trapping occurs by coupling between the valence band and the trap state,facilitated by the Br atoms surrounding the Bi dopant.Passivation of the DY−center with chlorines heals the local geometry distortion,eliminates the trap state,and makes the carrier lifetimes longer than even in pristine MAPbBr_(3).The decreased charge recombination arises from reduced nonadiabatic coupling and shortened coherence time,due to diminished electron–hole overlap around the passivated defect.Our study demonstrates accelerated nonradiative recombination in Bi-doped MAPbBr_(3),suggests a strategy for defect passivation and reduction of nonradiative energy losses,and provides atomistic insights into unusual defect properties of metal halide perovskites needed for rational design of high-performance perovskite solar cells and optoelectronic devices. | Ran Shi Wei-Hai Fang Andrey S.Vasenko Run Long Oleg V.Prezhdo | 2022 | Nano Research2022，15，3： | 0 |

| 11 | N-doped MoS_(2) via assembly transfer on an elastomeric substrate for high-photoresponsivity,air-stable and stretchable photodetector显示文摘As a direct-bandgap semiconductor,single-layer MoS_(2) has gained great attention in optoelectronics,especially wearable photodetectors.However,MoS_(2) exhibits poor photoresponsivity on a stretchable substrate due to intrinsic low carrier density and a large number of scattering centers on polymer substrates.Few air-stable yet strong dopants on MoS_(2) has been reported.In addition,the roughness,hydrophobicity and susceptibility to organic solvents of polymer surface are critical roadblocks in the development of stretchable high-performance MoS_(2) photodetectors.Here,we realize a stretchable and stable photodetector with high photoresponsivity by combining n-type dopant((4-(1,3-dimethyl-2,3-dihydro-1H-benzoimidazol-2-yl)phenyl)dimethylamine,N-DMBI)with MoS_(2) and assembly transfer technique.It is found electron tends to transfer from N-DMBI to MoS_(2) and the effect is maintained after the integrable photodetector transferred directly by elastic substrate styrene-ethylene-butylene-styrene(SEBS),even after being exposed to the air for 20 days,which benifits greatly from the encapsulation of SEBS.The increased carrier density greatly promotes carrier injection efficiency and photogenerated electron–hole separation efficiency at the metal–semiconductor interface,thus offering a significantly improved photoresponsivity in MoS_(2) photodetectors.Moreover,such photodetector shows great durability to stretch,which can remain functional after stretched 100 cycles within its stretch limit.Our strategy opens a new avenue to fabricate high-photoresponsivity stretchable electronics or optoelectronics of two-dimensional(2D)materials. | Shuyan Qi Weifeng Zhang Xiaoli Wang Yifan Ding Yan Zhang Jiakang Qiu Ting Lei Run Long Nan Liu | 2022 | Nano Research2022，15，11： | 0 |

| 13 | Developments and challenges ahead in blue perovskite light-emitting devices显示文摘Recently,perovskite light-emitting diodes(Pe LEDs)have developed rapidly in the green,red,and nearinfrared light emissions,owing to the unique optoelectronic characteristics of halide perovskites,such as high carrier mobility,narrow emission linewidths,high photoluminescence quantum yield,as well as bandgap tunability.However,the efficiency improvement in blue(especially deep-blue)Pe LEDs is still inferior to other analogs,which severely restricts the Pe LED applications.Here,we systematically summarize the substantial progress in the performance of blue Pe LEDs based on different blue perovskite candidates,and recent advances from three aspects(i.e.,the sky-blue,pure-blue,and deep-blue light emissions).Then,we point out several challenges existing in deep-blue Pe LEDs,such as the effect of Cl-ions incorporation,spectral instability,ion migration,and the difficulty of charge injection,and highlight the strategies to improve device efficiency,to motivate further research and development of blue Pe LEDs. | Lin Zhang Run Long | 2022 | Journal of Energy Chemistry2022，31，8： | 0 |
| 14 | Chemical passivation of methylammonium fragments eliminates traps,extends charge lifetimes,and restores structural stability of CH_(3)NH_(3)PbI_(3) perovskite显示文摘Hybrid organic-inorganic perovskites are currently considered the most promising next-generation photovoltaic material.However,poor stability,arising from structural degradation under exposure to moisture,heat,and strong current,remains a critical challenge for their device applications.Using ab initio nonadiabatic molecular dynamics,we demonstrate that methylamine fragments deriving from the dissociation of the methylammonium cation can undermine structural stability,produce deep hole traps,and decrease charge carrier lifetimes by 1-3 orders of magnitude.Both stability and charge lifetime can be restored by methylamine passivation with chlorines,which withdraw electrons from the lone electron pair of methylamine and bring the trap levels down into the valence band.The charge lifetime of the passivated system is even longer than that of the pristine perovskite.The simulations reveal the detailed microscopic mechanism underlying deterioration of perovskite performance due to molecular defects,and demonstrate an effective defect passivation strategy to obtain highly efficient and stable perovskite solar cells. | Xi Zhao Wei-Hai Fang Run Long Oleg V.Prezhdo | 2022 | Nano Research2022，15，5： | 0 |
