| 3 | 基于A位元素置换策略合成新型MAX相材料Ti_3ZnC_2显示文摘MAX相材料是一类兼具金属和陶瓷特性的三元层状材料,在高温导电、耐磨、耐腐蚀和耐辐照损伤等方面性能优异。目前已经合成出的MAX相材料已有70余种,但A位元素一直局限在ⅢA和ⅣA主族元素,如Al、Si、Ga等,而以副族元素占据A位的MAX相鲜有报道。本研究以Ti_3AlC_2为前驱体,利用熔盐中的A位置换反应,制备出了A位为Zn元素的全新MAX相材料Ti_3ZnC_2。结合X射线衍射、扫描电子显微镜和透射电子显微镜等分析手段对Ti_3ZnC_2的成分和结构进行了确认,并通过密度泛函理论对Ti_3ZnC_2的结构稳定性和晶格参数进行了确定。进一步通过热力学计算对Fe、Co、Ni、Cu等几种元素的A位置换反应进行了预测,发现采用这几种元素的氧化物进行置换反应在热力学上也都具有可行性。本研究所提出的元素置换策略是在保持MAX相六方层状晶体结构的基础上,利用Al、Zn在高温下形成共晶产物实现Zn原子向A层内的迁移,而熔盐介质的存在促进了反应动力学。本方法巧妙地避免了MAX相传统合成过程中竞争相的形成,如M-A合金相,因此可以用于探索更多未知的MAX相材料。 | 李勉 李友兵 罗侃 LU Jun EKLUND Per PERSSON Per ROSEN Johanna HULTMAN Lars 都时禹 黄政仁 黄庆 | 2019 | 无机材料学报2019,34,1: | 14 |
| 4 | Effective mass and Fermi surface complexity factor from ab initio band structure calculations显示文摘The effective mass is a convenient descriptor of the electronic band structure used to characterize the density of states and electron transport based on a free electron model.While effective mass is an excellent first-order descriptor in real systems,the exact value can have several definitions,each of which describe a different aspect of electron transport.Here we use Boltzmann transport calculations applied to ab initio band structures to extract a density-of-states effective mass from the Seebeck Coefficient and an inertial mass from the electrical conductivity to characterize the band structure irrespective of the exact scattering mechanism.We identify a Fermi Surface Complexity Factor:N_(v)^(*)K^(*) from the ratio of these two masses,which in simple cases depends on the number of Fermi surface pockets eN_(v)^(*) T and their anisotropy K^(*),both of which are beneficial to high thermoelectric performance as exemplified by the high values found in PbTe.The Fermi Surface Complexity factor can be used in high-throughput search of promising thermoelectric materials. | Zachary M.Gibbs Francesco Ricci Guodong Li Hong Zhu Kristin Persson Gerbrand Ceder Geoffroy Hautier Anubhav Jain G.Jeffrey Snyder | 2017 | npj Computational Materials2017,,1: | 11 |
| 5 | Active learning for accelerated design of layered materials显示文摘Hetero-structures made from vertically stacked monolayers of transition metal dichalcogenides hold great potential for optoelectronic and thermoelectric devices.Discovery of the optimal layered material for specific applications necessitates the estimation of key material properties,such as electronic band structure and thermal transport coefficients.However,screening of material properties via brute force ab initio calculations of the entire material structure space exceeds the limits of current computing resources.Moreover,the functional dependence of material properties on the structures is often complicated,making simplistic statistical procedures for prediction difficult to employ without large amounts of data collection.Here,we present a Gaussian process regression model,which predicts material properties of an input hetero-structure,as well as an active learning model based on Bayesian optimization,which can efficiently discover the optimal hetero-structure using a minimal number of ab initio calculations.The electronic band gap,conduction/valence band dispersions,and thermoelectric performance are used as representative material properties for prediction and optimization.The Materials Project platform is used for electronic structure computation,while the BoltzTraP code is used to compute thermoelectric properties.Bayesian optimization is shown to significantly reduce the computational cost of discovering the optimal structure when compared with finding an optimal structure by building a regression model to predict material properties.The models can be used for predictions with respect to any material property and our software,including data preparation code based on the Python Materials Genomics(PyMatGen)library as well as python-based machine learning code,is available open source. | Lindsay Bassman Pankaj Rajak Rajiv K.Kalia Aiichiro Nakano Fei Sha Jifeng Sun David J.Singh Muratahan Aykol Patrick Huck Kristin Persson Priya Vashishta | 2018 | npj Computational Materials2018,,1: | 10 |
| 6 | Active suspension in railway vehicles:a literature survey显示文摘Since the concept of active suspensions appeared,its large possible benefits has attracted continuous exploration in the field of railway engineering.With new demands of higher speed,better ride comfort and lower maintenance cost for railway vehicles,active suspensions are very promising technologies.Being the starting point of commercial application of active suspensions in rail vehicles,tilting trains have become a great success in some countries.With increased technical maturity of sensors and actuators,active suspension has unprecedented development opportunities.In this work,the basic concepts are summarized with new theories and solutions that have appeared over the last decade.Experimental studies and the implementation status of different active suspension technologies are described as well.Firstly,tilting trains are briefly described.Thereafter,an indepth study for active secondary and primary suspensions is performed.For both topics,after an introductory section an explanation of possible solutions existing in the literature is given.The implementation status is reported.Active secondary suspensions are categorized into active and semi-active suspensions.Primary suspensions are instead divided between acting on solid-axle wheelsets and independently rotating wheels.Lastly,a brief summary and outlook is presented in terms of benefits,research status and challenges.The potential for active suspensions in railway applications is outlined. | Bin Fu Rocco Libero Giossi Rickard Persson Sebastian Stichel Stefano Bruni Roger Goodall | 2020 | Railway Engineering Science2020,28,1: | 8 |
| 7 | Multi-omics analyses of 398 foxtail millet accessions reveal genomic regions associated with domestication,metabolite traits,and antiinflammatory effects显示文摘Foxtail millet(Setaria italica),which was domesticatedfromthewild speciesgreenfoxtail(Setaria viridis),isa richsource of phytonutrientsfor humans.To evaluate how breeding changed themetabolome offoxtail millet grains,we generated and analyzed the datasets encompassing the genomes,transcriptomes,metabolomes,and anti-inflammatory indices from 398 foxtail millet accessions.We identified hundreds of common variants that influence numerous secondary metabolites.We observed tremendous differences in natural variations of the metabolites and their underlying genetic architectures between distinct sub-groups of foxtail millet.Furthermore,we found that the selection of the gene alleles associated with yellow grains led to altered profiles of metabolites such as carotenoids and endogenous phytohormones.Using CRiSPR-mediated genome editing wevalidated the function of PHYTOENE SYNTHASE1(PSY1)gene in affecting milletgrain colorand quality.Interestingly,our in vitro cell inflammation assays showed that 83 metabolites in millet grains have anti-inflammatory effects.Taken together,ourmulti-omics study illustrates how the breeding history of foxtail millet has shaped its metabolite profile.The datasets we generated in this study also provide important resources for further understanding how millet grain quality is affected by different metabolites,laying the foundations for future millet genetic research and metabolome-assisted improvement. | Xukai Li Jianhua Gao Jingyi Song Kai Guo Siyu Hou Xingchun Wang Qiang He Yanyan Zhang Yakun Zhang Yulu Yang Jiaoyan Tang Hailang Wang Staffan Persson Mingquan Huang Lishuai Xu Linlin Zhong Dongqin Li Yongming Liu Hua Wu Xianmin Diao Peng Chen Xiaowen Wang Yuanhuai Han | 2022 | Molecular Plant2022,15,8: | 8 |

| 9 | The connection of cytoskeletal network with plasma membrane and the cell wall显示文摘The cell wall provides external support of the plant cells, while the cytoskeletons including the microtubules and the actin filaments constitute an internal framework. The cytoskeletons contribute to the cell wall biosynthesis by spatially and temporarily regulating the transportation and deposition of cell wall components. This tight control is achieved by the dynamic behavior of the cytoskeletons, but also through the tethering of these structures to the plasma membrane. This tethering may also extend beyond the plasma membrane and impact on the cell wall, possibly in the form of a feedback loop. In this review, we discuss the linking components between the cytoskeletons and the plasma membrane, and/or the cell wall. We also discuss the prospective roles of these components in cell wall biosynthesis and modifications, and aim to provide a platform for further studies in this field. | Zengyu Liu Staffan Persson Yi Zhang | 2015 | Journal of Integrative Plant Biology2015,57,4: | 6 |
| 10 | Predicting defect behavior in B2 intermetallics by merging ab initio modeling and machine learning显示文摘We present a combination of machine learning and high throughput calculations to predict the points defects behavior in binary intermetallic(A–B)compounds,using as an example systems with the cubic B2 crystal structure(with equiatomic AB stoichiometry).To the best of our knowledge,this work is the first application of machine learning-models for point defect properties.High throughput first principles density functional calculations have been employed to compute intrinsic point defect energies in 100 B2 intermetallic compounds.The systems are classified into two groups:(i)those for which the intrinsic defects are antisites for both A and B rich compositions,and(ii)those for which vacancies are the dominant defect for either or both composition ranges.The data was analyzed by machine learning-techniques using decision tree,and full and reduced multiple additive regression tree(MART)models.Among these three schemes,a reduced MART(r-MART)model using six descriptors(formation energy,minimum and difference of electron densities at the Wigner–Seitz cell boundary,atomic radius difference,maximal atomic number and maximal electronegativity)presents the highest fit(98%)and predictive(75%)accuracy.This model is used to predict the defect behavior of other B2 compounds,and it is found that 45%of the compounds considered feature vacancies as dominant defects for either A or B rich compositions(or both).The ability to predict dominant defect types is important for the modeling of thermodynamic and kinetic properties of intermetallic compounds,and the present results illustrate how this information can be derived using modern tools combining high throughput calculations and data analytics. | Bharat Medasani Anthony Gamst Hong Ding Wei Chen Kristin A Persson Mark Asta Andrew Canning Maciej Haranczyk | 2016 | npj Computational Materials2016,,1: | 6 |

| 12 | Investigation of CRISPR/Cas9-induced SD1 rice mutants highlights the importance of molecular characterization in plant molecular breeding显示文摘Although Clustered Regularly Interspaced Short Palindromic Repeats(CRISPR)/CRISPR-associated 9(Cas9)system has been widely used for basic research in model plants,its application for applied breeding in crops has faced strong regulatory obstacles,due mainly to a poor understanding of the authentic output of this system,particularly in higher generations.In this study,different from any previous studies,we investigated in detail the molecular characteristics and production performance of CRISPR/Cas9-generated SD1(semi-dwarf 1)mutants from T2 to T4 generations,of which the selection of T1 and T2 was done only by visual phenotyping for semidwarf plants.Our data revealed not only on-and off-target mutations with small or lager indels but also exogenous elements in T2 plants.All indel mutants passed stably to T3 or T4 without additional modifications independent on the presence of Cas9,while some lines displayed unexpected hereditary patterns of Cas9 or some exogenous elements.In addition,effects of various SD1 alleles on rice height and yield differed depending on genetic backgrounds.Taken together,our data showed that the CRISPR/Cas9 system is effective in producing homozygous mutants for functional analysis,but it may be not as precise as expected in rice,and that early and accurate molecular characterization and screening must be carried out for generations before transitioning of the CRISPR/Cas9 system from laboratory to field. | Sukumar Biswas Jiaqi Tian Rong Li Xiaofei Chen Zhijing Luo Mingjiao Chen Xiangxiang Zhao Dabing Zhang Staffan Persson Zheng Yuan Jianxin Shi | 2020 | Journal of Genetics and Genomics2020,47,5: | 4 |

| 14 | High-throughput prediction of the ground-state collinear magnetic order of inorganic materials using Density Functional Theory显示文摘We present a robust,automatic high-throughput workflow for the calculation of magnetic ground state of solid-state inorganic crystals,whether ferromagnetic,antiferromagnetic or ferrimagnetic,and their associated magnetic moments within the framework of collinear spin-polarized Density Functional Theory.This is done through a computationally efficient scheme whereby plausible magnetic orderings are first enumerated and prioritized based on symmetry,and then relaxed and their energies determined through conventional DFT+U calculations.This automated workflow is formalized using the atomate code for reliable,systematic use at a scale appropriate for thousands of materials and is fully customizable.The performance of the workflow is evaluated against a benchmark of 64 experimentally known mostly ionic magnetic materials of non-trivial magnetic order and by the calculation of over 500 distinct magnetic orderings.A non-ferromagnetic ground state is correctly predicted in 95% of the benchmark materials,with the experimentally determined ground state ordering found exactly in over 60% of cases.Knowledge of the ground state magnetic order at scale opens up the possibility of high-throughput screening studies based on magnetic properties,thereby accelerating discovery and understanding of new functional materials. | Matthew Kristofer Horton Joseph Harold Montoya Miao Liu Kristin Aslaug Persson | 2019 | npj Computational Materials2019,,1: | 3 |
