| 1 | A natural variation in Ribonuclease H-like gene underlies Rht8 to confer“Green Revolution”trait in wheat显示文摘Dear Editor,Introduction of gibberellin(GA)-insensitive Reduced height(Rht)genes,Rht-B1b and Rht-D1b,has resulted in the“Green Revolution”in modern wheat cultivars(Triticum aestivum)that has skyrocketed wheat grain yields worldwide since the 1960s(Peng et al.,1999;Velde et al.,2021).However,Rht-B1b/D1b also reduce coleoptiles,which is undesired in dryland regions where deep planting is essential for seedling establishment(Rebetzke et al.,1999,Rebetzke et al.,2001;Ellis et al.,2004). | Lingling Chai Mingming Xin Chaoqun Dong Zhaoyan Chen Huijie Zhai Junhong Zhuang Xuejiao Cheng Naijiao Wang Jia Geng Xiaobo Wang Ruolin Bian Yingyin Yao Weilong Guo Zhaorong Hu Huiru Peng Guihua Bai Qixin Sun Zhenqi Su Jie Liu Zhongfu Ni | 2022 | Molecular Plant2022，15，3： | 8 |
| 2 | TOOL PATH PLANNING USING VORONOI DIAGRAM AND THREE STACKS显示文摘Based on the object oriented data structure of Voronoi diagram, the algorithm of the trimmed offset generating and the optimal too l path planning of the pocket machining for multiply connected polygonal domains are studied. The intersection state transition rule is improved in this algorithm. The intersection is between the trimmed offsets and Voronoi polygon. On this basis, the trimmed offset generating and the optimal tool path planning are mad e with three stacks(I stack, C stack and P stack)in different monotonous pouches of Voronoi diagram. At the same time, a merging method of Voronoi diagram an d offsets generating for multiply connected polygonal domains is also presented. The above algorithms have been implemented in NC machining successfully, and the efficiency is fully verified. | Fu Zhuang,Liu Chengliang,Yin Yuehong,Cao Qixin,Ma Peixun (Research Institute of Robotics, Shanghai Jiaotong University) Wang Shuguo (Harbin Institute of Technology) | 2001 | Chinese Journal of Mechanical Engineering2001，14，4： | 5 |
| 3 | Simultaneous passivation of bulk and interface defects through synergistic effect of anion and cation toward efficient and stable planar perovskite solar cells显示文摘Bulk and interface carrier nonradiative recombination losses impede the further improvement of power conversion efficiency(PCE)and stability of perovskite solar cells(PSCs).It is highly necessary to develop multifunctional strategy to minimize surface and interface nonradiative recombination losses.Herein,we report a bulk and interface defect passivation strategy via the synergistic effect of anions and cations,where multifunctional potassium sulphate(K_(2)SO_(4))is incorporated at SnO_(2)/perovskite interface.We find that K^(+)ions in K_(2)SO_(4)diffuse into perovskite layer and suppress the formation of bulk defects in perovskite films,and the SO_(4)^(2-)ions remain located at interface via the strong chemical interaction with SnO_(2)layer and perovskite layer,respectively.Through this synergistic modification strategy,effective defect passivation and improved energy band alignment are achieved simultaneously.These beneficial effects are translated into an efficiency increase from 19.45%to 21.18%with a low voltage deficit of0.53 V mainly as a result of boosted open-circuit voltage(V_(oc))after K_(2)SO_(4)modification.In addition,the K_(2)SO_(4)modification contributes to ameliorated stability.The present work provides a route to minimize bulk and interface nonradiative recombination losses for the simultaneous realization of PCE and stability enhancement by rational anion and cation synergistic engineering. | Cong Zhang Huaxin Wang Haiyun Li Qixin Zhuang Cheng Gong Xiaofei Hu Wensi Cai Shuangyi Zhao Jiangzhao Chen Zhigang Zang | 2021 | Journal of Energy Chemistry2021，30，12： | 2 |
| 4 | Bottom-up holistic carrier management strategy induced synergistically by multiple chemical bonds to minimize energy losses for efficient and stable perovskite solar cells显示文摘The defects from electron transport layer,perovskite layer and their interface would result in carrier nonradiative recombination losses.Poor buried interfacial contact is detrimental to charge extraction and device stability.Here,we report a bottom-up holistic carrier management strategy induced synergistically by multiple chemical bonds to minimize bulk and interfacial energy losses for high-performance perovskite photovoltaics.4-trifluoromethyl-benzamidine hydrochloride(TBHCl)containing–CF_(3),amidine cation and Cl^(-)is in advance incorporated into SnO_(2)colloid solution to realize bottom-up modification.The synergistic effect of multiple functional groups and multiple-bond-induced chemical interaction are revealed theoretically and experimentally.F and Cl^(-)can passivate oxygen vacancy and/or undercoordinated Sn^(4+)defects by coordinating with Sn^(4+).The F can suppress cation migration and modulate crystallization via hydrogen bond with FA^(+),and can passivate lead defects by coordinating with Pb^(2+).The–NH_(2)–C=NH^(+)_(2)and Cl^(-)can passivate cation and anion vacancy defects through ionic bonds with perovskites,respectively.Through TBHCl modification,the suppression of agglomeration of SnO_(2)nanoparticles,bulk and interfacial defect passivation,and release of tensile strains of perovskite films are demonstrated,which resulted in a PCE enhancement from 21.28%to 23.40%and improved stability.With post-treatment,the efficiency is further improved to 23.63%. | Baibai Liu Ru Li Qixin Zhuang Xuemeng Yu Shaokuan Gong Dongmei He Qian Zhou Hua Yang Xihan Chen Shirong Lu Zong-Xiang Xu Zhigang Zang Jiangzhao Chen | 2023 | Journal of Energy Chemistry2023，，1： | 1 |

| 18 | The Spatial and Electronic Effects of Substituent Groups on the Thermal Curing of Bio-Based Benzoxazines显示文摘To explore the influence of substituent groups on thermally induced curing,eight new bio-based benzoxazines containing different substituent groups with different electron negativity and volumes were synthesized.The thermal curing of these bio-based benzoxazines was studied in detail.Combined with the curing reaction kinetics,simulation and calculation of Highest Occupied Molecular and Lowest Unoccupied Molecular values,the spatial and electronic effects of different substituent groups on the curing of benzoxazine was explored.It was found that when the substituent was located at the position directly connected to the N atom,the steric hindrance effect of the group was dominant.When the substituent group was located on the benzene ring connected to the O atom,both the electronic effect and the spatial effect influenced the curing of benzoxazine.When an electron-withdrawing group was connected ortho position to the O atom,the curing reaction was promoted due to the decreased electron cloud density of O-on the oxazine ring,making the C-O bond easier to break.When an electron-donating group was connected to the meta position of the O atom it also promoted the curing reaction,possibly because it increased the electron cloud density of the+CH2 reaction site and thereby facilitated electrophilic substitution via attack of+CH2 on the cross linking reaction centre.This work provides a deeper understanding of how spatial and electronic effects of substituents affect the curing of benzoxazine. | Rumeng Li Guozhu Zhan Qi Ma Yunhe Yang Xiaoyun Liu Yitong Zhang Qixin Zhuang | 2021 | Journal of Renewable Materials2021，9，12： | 0 |
| 19 | Ion diffusion-induced double layer doping toward stable and efficient perovskite solar cells显示文摘The perovskite layer,electron transport layer(ETL)and their interface are closely associated with carrier transport and extraction,which possess a pronounced effect on current density.Consequently,the dissatisfactory electric properties of functional layers pose a serious challenge for maximizing the thermodynamic potential of current density of perovskite solar cells(PSCs).Herein,we report an ion diffusion-induced double layer doping strategy for efficient and stable PSCs,where LiOH is directly added into SnO_(2)colloidal dispersion solution.It is uncovered that a small amount of Li+ions remain in the ETL and doped SnO2 while a large amount of Li+ions diffuse to SnO_(2)/perovskite interface and into perovskite layer and gradient concentration distribution is spontaneously formed.The Li+ion doping endows both perovskite and SnO_(2)layers improved electric properties,which contributes to facilitated carrier transport and extraction.Moreover,the crystallinity and grain size of perovskite films are enhanced after doping.The doped device delivers a higher power conversion efficiency(PCE)of 21.31%together with improved ambient stability in comparison with the control device(PCE=19.26%).This work demonstrates a simple and effective ion diffusion-induced double layer by chemical doping strategy to advance the development of perovskite photovoltaics. | Qixin Zhuang Huaxin Wang Cong Zhang Cheng Gong Haiyun Li Jiangzhao Chen Zhigang Zang | 2022 | Nano Research2022，15，6： | 0 |
| 20 | Fabrication and Investigation on Double-Hollow Shell CoFe Oxide@TiO_(2) Nanocube with Superior Electromagnetic Properties显示文摘Electromagnetic wave absorbing materials are urgently required in the fields of medicine,communication,and military.However,the thickness,weight,narrow effective bandwidth,and weak absorbing ability of the materials restrict their further application.In this work,a double-layer hollow nanocube with a dielectric titanium dioxide(TiO_(2))shell and a magnetic CoFe oxide inner shell is prepared.Prussian blue(PB)is prepared by the hydrothermal method,and used as the template to prepare PB@CoFe PB analogue(PBA).After selective etching and further calcination,hollow CoFe oxide particles are obtained.The obtained particles are then coated with SiO_(2)and TiO_(2),respectively,and the intermediate layer is dislodged to obtain the final CoFe oxide@TiO_(2)with the hollow double shell structure.The obtained double-layer hollow structure can effectively capture the incident electromagnetic waves,and increase the propagation path.Moreover,the obvious enhancement of interface polarization and the improvement of impedance matching enhance the wave absorbing ability of the material.The analysis results show that,the structure is stable and the dispersion is good.The maximum reflection loss(RL)at 10 GHz is as high as-46.1 dB with the sample thickness of 1.6 mm.The light-weight and high-efficiency CoFe oxide@TiO_(2)absorber is promised to be used in commercial and military aerospace fields. | NI Xinyao TANG Chuanhao HUA Jiasong CHEN Yi ZHUANG Qixin | 2022 | 上海航天(中英文)2022，39，1： | 0 |
