| 1 | Ultrafast epitaxial growth of metre-sized single-crystal graphene on industrial Cu foil显示文摘A foundation of the modern technology that uses single-crystal silicon has been the growth of highquality single-crystal Si ingots with diameters up to 12 inches or larger. For many applications of graphene, large-area high-quality(ideally of single-crystal) material will be enabling. Since the first growth on copper foil a decade ago, inch-sized single-crystal graphene has been achieved. We present here the growth, in 20 min, of a graphene film of(5 ×50) cm^2 dimension with >99% ultra-highly oriented grains.This growth was achieved by:(1) synthesis of metre-sized single-crystal Cu(1 1 1) foil as substrate;(2)epitaxial growth of graphene islands on the Cu(1 1 1) surface;(3) seamless merging of such graphene islands into a graphene film with high single crystallinity and(4) the ultrafast growth of graphene film.These achievements were realized by a temperature-gradient-driven annealing technique to produce single-crystal Cu(1 1 1) from industrial polycrystalline Cu foil and the marvellous effects of a continuous oxygen supply from an adjacent oxide. The as-synthesized graphene film, with very few misoriented grains(if any), has a mobility up to ~23,000 cm^2 V^(-1)s^(-1)at 4 K and room temperature sheet resistance of ~230 Ω/□. It is very likely that this approach can be scaled up to achieve exceptionally large and high-quality graphene films with single crystallinity, and thus realize various industrial-level applications at a low cost. | Xiaozhi Xu Zhihong Zhang Jichen Dong Ding Yi Jingjing Niu Muhong Wu Li Lin Rongkang Yin Mingqiang Li Jingyuan Zhou Shaoxin Wang Junliang Sun Xiaojie Duan Peng Gao Ying Jiang Xiaosong Wu Hailin Peng Rodney S.

| 2 | 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%.

| 3 | Facile fabrication of paper-based flexible thermoelectric generator显示文摘Paper,as a foldable,pollution-free,and low-cost material,has become a suitable support substrate for producing flexible thermoelectric(TE)generators to realize waste heat recycling and the application of human-powered electronic devices.We propose a facile fabrication method to modify cellulose paper with inorganic TE powders via vacuum filtration,making a modified paper that possesses good thermoelectric properties.By connecting the modified paper to copper foils,flexible paper-based TE generators(PTGs)are fabricated.The obtained PTG with three units of P–N modules can generate an output voltage of∼41.2 mV at a temperature difference of 50 K.Based on this modified paper,a thermal sensor that responds to heat sources,such as fingers,is proposed with a rapid response time of 0.25 s.This work offers a promising strategy for the simple fabrication of PTGs,paving the way for achieving the commercial application of self-powered wearable electronics. | Zuoyuan Dong Hua Liu Xin Yang Jichen Fan Hengchang Bi Chaolun Wang Yonghua Zhang Chen Luo Xinqian Chen Xing Wu | 2021 | npj Flexible Electronics2021，5，1： | 1 |

| 5 | Multi-stage anisotropic etching of two-dimensional heterostructures显示文摘Regarding the reverse process of materials growth,etching has been widely concerned to indirectly probe the growth kinetics,offering an avenue in governing the growth of two-dimensional(2D)materials.In this work,interface-driven anisotropic etching mode is demonstrated for the first time to be generally applied to 2D heterostructures.It is shown that the typical in-plane graphene and hexagonal boron nitride(h-BN)heterostructures follow a multi-stage etching behavior initiated first along the interfacial region between the two materials and then along edges of neighboring h-BN flakes and finally along central edges of hBN.By accurately tuning etching conditions in the chemical vapor deposition process,series of etched 2D heterostructure patterns are controllably produced.Furthermore,scaled formation of graphene and h-BN heterostructures arrays has been realized with full assist of as-proposed etching mechanism,offering a direct top-down method to make 2D orientated heterostructures with order and complexity.Detection of interface-driven multi-staged anisotropic etching mode will shed light on understanding growth mechanism and further expanding wide applications of 2D heterostructures. | Lin Li Jichen Dong Dechao Geng Menghan Li Wei Fu Feng Ding Wenping Hu Hui Ying Yang | 2022 | Nano Research2022，15，6： | 0 |

| 7 | Mechanisms of the epitaxial growth of two-dimensional polycrystals显示文摘In the epitaxial growth of two-dimensional(2D)materials on substrates,2D polycrystals with various shapes have been broadly observed,but their formation mechanisms are still highly elusive.Here we present a complete study on the formation mechanisms of various 2D polycrystals.The structures of the 2D polycrystals are dependent on the symmetries of both the 2D material and the substrate.We build four complete libraries of 2D polycrystals for(i)threefold symmetric 2D materials on two-or six-fold symmetric substrates(i.e.,family-Ⅲ/Ⅱor-Ⅲ/Ⅵ),(ii)threefold symmetric 2D materials on fourfold symmetric substrates(i.e.family-Ⅲ/Ⅳ),(iii)fourfold symmetric 2D materials on three-or six-fold symmetric substrates(i.e.,family-Ⅳ/Ⅲor-Ⅳ/Ⅵ),and(iv)sixfold symmetric 2D materials on fourfold symmetric substrates(i.e.,family-Ⅵ/Ⅳ),respectively.The four libraries of 2D polycrystals are consistent with many existing experimental observations and can be used to guide the experimental synthesis of various 2D polycrystals. | Jichen Dong Yunqi Liu Feng Ding | 2022 | npj Computational Materials2022，，1： | 0 |
