| 1 | Progress of the key materials for organic solar cells显示文摘Organic solar cells have attracted academic and industrial interests due to the advantages like lightweight,flexibility and roll-to-roll fabrication.Nowadays,18%power conversion efficiency has been achieved in the state-of-the-art organic solar cells.The recent rapid progress in organic solar cells relies on the continuously emerging new materials and device fabrication technologies,and the deep understanding on film morphology,molecular packing and device physics.Donor and acceptor materials are the key materials for organic solar cells since they determine the device performance.The past 25 years have witnessed an odyssey in developing high-performance donors and acceptors.In this review,we focus on those star materials and milestone work,and introduce the molecular structure evolution of key materials.These key materials include homopolymer donors,D-A copolymer donors,A-D-A small molecular donors,fullerene acceptors and nonfullerene acceptors.At last,we outlook the challenges and very important directions in key materials development. | Yang Tong Zuo Xiao Xiaoyan Du Chuantian Zuo Yuelong Li Menglan Lv Yongbo Yuan Chenyi Yi Feng Hao Yong Hua Ting Lei Qianqian Lin Kuan Sun Dewei Zhao Chunhui Duan Xiangfeng Shao Wei Li Hin-Lap Yip Zhengguo Xiaol Bin Zhang Qingzhen Bian Yuanhang Cheng Shengjian Liu Ming Cheng Zhiwen Jin Shangfeng Yang Liming Ding | 2020 | Science China Chemistry2020，63，6： | 15 |
| 2 | CuTiNiZrV Amorphous Alloy Foils for Vacuum Brazing of TiAl Alloy to 40Cr Steel显示文摘Vacuum brazing of TiAl alloy to 40Cr steel sheets was conducted with newly developed CuTiNiZrV amorphous foils. It was found that a diffusion layer,filler metal and reaction layer existed in the brazed seam. The diffusion layer in the joint brazed with Cu43.75Ti37.5Ni6.25Zr6.25V6.25(at.%) foil was flat and thin,containing Ti19Al6 and Ti2Cu intermetallic compounds; however,the diffusion layer brazed with Cu37.5Ti25Ni12.5Zr12.5V12.5 foil was uneven with bulges,consisting of essentially Ti-based solute solution. The foil with 12.5 at.% V showed inferior spreadability compared to that with 6.25 at.% V at brazing temperature. However,fracture happened along the diffusion layer with 6.25 at.% V foil due to the formation of brittle intermetallic phases,but the joints brazed with 12.5 at.% V foil failed through the TiAl substrate. These results show that designing amorphous alloy with less Ti and more V for brazing TiAl alloy to steel is appropriate. | Honggang Dong Zhonglin Yang Zengrui Wang Dewei Deng Chuang Dong | 2015 | Journal of Materials Science & Technology2015，31，2： | 7 |
| 3 | Dynamic route guidance algorithm based onartificial immune system显示文摘To improve the performance of the K-shortest paths search in intelligent traffic guidance systems,this paper proposes an optimal search algorithm based on the intelligent optimization search theory and the metaphor mechanism of vertebrate immune systems.This algorithm,applied to the urban traffic network model established by the node-expanding method,can expediently realize K-shortest paths search in the urban traffic guidance systems.Because of the immune memory and global parallel search ability from artificial immune systems,K shortest paths can be found without any repeat,which indicates evidently the superiority of the algorithm to the conventional ones.Not only does it perform a better parallelism,the algorithm also prevents premature phenomenon that often occurs in genetic algorithms.Thus,it is especially suitable for real-time requirement of the traffic guidance system and other engineering optimal applications.A case study verifies the efficiency and the practicability of the algorithm aforementioned. | Licai YANG Jie LIN Dewei WANG Lei JIA | 2007 | 控制理论与应用(英文版)2007，5，4： | 7 |
| 4 | Materials evolution of bone plates for internal fixation of bone fractures:A review显示文摘Bone plates play a vital role in bone fracture healing by providing the necessary mechanical fixation for fracture fragments through modulating biomechanical microenvironment adjacent to the fracture site.Good treatment effect has been achieved for fixation of bone fracture with conventional bone plates,which are made of stainless steel or titanium alloy.However,several limitations still exist with traditional bone plates including loosening and stress shielding due to significant difference in modulus between metal material and bone tissue that impairs optimal fracture healing.Additionally,due to demographic changes and non-physiological loading,the population suffering from refractory fractures,such as osteoporosis fractures and comminuted fractures,is increasing,which imposes a big challenge to traditional bone plates developed for normal bone fracture repair.Therefore,optimal fracture treatment with adequate fixation implants in terms of materials and design relevant to special conditions is desirable.In this review,the complex physiological process of bone healing is introduced,followed by reviewing the development of implant design and biomaterials for bone plates.Finally,we discuss recent development of hybrid bone plates that contains bioactive elements or factors for fracture healing enhancement as a promising direction.This includes biodegradable Mg-based alloy used for designing bone screw-plates that has been proven to be beneficial for fracture healing,an innovative development that attracts more and more attention.This paper also indicates that the tantalum bone plates with porous structure are also emerging as a new fracture internal fixation implants.The reduction of the stress shielding is verified to be useful to accelerate bone fracture healing.Potential application of biodegradable metals may also avoid a second operation for implant removal.Further developments in biometals and their design for orthopedic bone plates are expected to improve the treatment of bone fracture,especially the refractory fractures. | Junlei Li Ling Qin Ke Yang Zhijie Ma Yongxuan Wang Liangliang Cheng Dewei Zhao | 2020 | Journal of Materials Science & Technology2020，36，1： | 5 |
| 5 | The effects of orientation control via tension-compression on microstructural evolution and mechanical behavior of AZ31 Mg alloy sheet显示文摘The grain orientation control via twinning activity on deformation features is of great significance to offer a key insight into understanding the deformation mechanism of Mg alloy sheets.The{10–12}twinning were performed by pre-strain paths,i.e.,tension(6%)and compression(5%)perpendicular to the c-axis along extrusion direction(ED),to investigate the microstructural evolution and mechanical properties of AZ31 Mg alloy sheets.The distinction in the texture evolution and strain hardening behavior was illustrated in connection with the pre-strain paths for the activities of twinning and slip.The result shows that the activation of the deformation mode was closely bound up with the grain orientation and the additional applied load direction.The{10–12}twin-texture components with c-axis//ED were generated by precompression,which can provide an appropriate alternative to accommodate the thin sheet thickness strain and enhance the room temperature formability of Mg alloy sheet. | Qingshan Yang Bin Jiang Bo Song Zujian Yu Dewei He Yanfu Chai Jianyue Zhang Fusheng Pan | 2022 | Journal of Magnesium and Alloys2022，10，2： | 4 |
| 6 | In vitro and in vivo studies on the biodegradable behavior and bone response of Mg69Zn27Ca4 metal glass for treatment of bone defect显示文摘In the present work, the biodegradable behavior, cytocompatibility and osteogenesis activity of a Mg69Zn27Ca4 metal glass were investigated. Electrochemical test, immersion test, cytotoxicity test and histopathological evaluation were carried out. The results showed that there was a dense protective layer formed on the surface of Mg69Zn27Ca4 metal glass which could inhibit the degradation process in the Hank’s solution. In vitro cytotoxicity test showed that Mg69Zn27Ca4 metal glass had good biocompatibility. Histopathological evaluation showed that the degradation of Mg69Zn27Ca4 metal glass could promote the new bone formation with no obvious inflammatory reactions. After 2 months implantation, the diameter of the bone defect was reduced from the original φ6 mm to φ3.35 ± 0.40 mm with the degradation of Mg69Zn27Ca4 metal glass. Therefore, it can be concluded that Mg69Zn27Ca4 glass has great potential to be used as bone substitutes. | Junxiu Chen Jiahui Dong Huameng Fu Haifeng Zhang Lili Tan Dewei Zhao Ke Yang | 2019 | Journal of Materials Science & Technology2019，35，10： | 4 |
| 7 | Decomposition and decoupling analysis of carbon dioxide emissions in African countries during 1984–2014显示文摘The potential for mitigating climate change is growing worldwide,with an increasing emphasis on reducing CO_(2)emissions and minimising the impact on the environment.African continent is faced with the unique challenge of climate change whilst coping with extreme poverty,explosive population growth and economic difficulties.CO_(2)emission patterns in Africa are analysed in this study to understand primary CO_(2)sources and underlying driving forces further.Data are examined using gravity model,logarithmic mean divisia index and Tapio's decoupling indicator of CO_(2)emissions from economic development in 20 selected African countries during 1984-2014.Results reveal that CO_(2)emissions increased by 2.11%(453.73 million ton)over the research period.Gravity centre for African CO_(2)emissions had shifted towards the northeast direction.Population and economic growth were primary driving forces of CO_(2)emissions.Industrial structure and emission efficiency effects partially offset the growth of CO_(2)emissions.The economic growth effect was an offset factor in central African countries and Zimbabwe due to political instability and economic mismanagement.Industrial structure and emission efficiency were insufficient to decouple economic development from CO_(2)emissions and relieve the pressure of population explosion on CO_(2)emissions in Africa.Thus,future efforts in reducing CO_(2)emissions should focus on scaleup energy-efficient technologies,renewable energy update,emission pricing and long-term green development towards sustainable development goals by 2030. | Claudien Habimana Simbi Jianyi Lin Dewei Yang Jean Claude Ndayishimiye Yang Liu Huimei Li Lingxing Xu Weijing Ma | 2021 | Journal of Environmental Sciences2021，33，4： | 3 |
| 8 | Porous silicon carbide coated with tantalum as potential material for bone implants显示文摘Porous silicon carbide(SiC)has a specific biomorphous microstructure similar to the trabecular microstructure of human bone.Compared with that of bioactive ceramics,such as calcium phosphate,SiC does not induce spontaneous interface bonding to living bone.In this study,bioactive tantalum(Ta)metal deposited on porous SiC scaffolds by chemical vapour deposition was investigated to accelerate osseointegration and improve the bonding to bones.Scanning electron microscopy indicated that the Ta coating evenly covered the entire scaffold structure.Energy-dispersive spectroscopy and X-ray diffraction analysis showed that the coating consisted of Ta phases.The bonding strength between the Ta coating and the SiC substrate is 88.4MPa.The yield strength of porous SiC with a Ta coating(pTa)was 45.862.9MPa,the compressive strength was 61.463.2MPa and the elasticmodulus was4.8GPa.When MG-63 human osteoblasts were co-cultured with pTa,osteoblasts showed good adhesion and spreading on the surface of the pTa and its porous structure,which showed that it has excellent bioactivity and cyto-compatibility.To further study the osseointegration properties of pTa.PTa and porous titanium(pTi)were implanted into the femoral neck of goats for 12weeks,respectively.The Van-Gieson staining of histological sections results that the pTa group had better osseointegration than the pTi group.These results indicate that coating bioactive Ta metal on porous SiC scaffolds could be a potential material for bone substitutes. | Zhijie Ma Jingyu Li Fang Cao Jiahui Yang Rong Liu Dewei Zhao | 2020 | Regenerative Biomaterials2020，7，5： | 3 |
| 9 | Cyst(e)ine in nutrition formulation promotes colon cancer growth and chemoresistance by activating mTORCl and scavenging ROS显示文摘Weight loss and cachexia are common problems in colorectal cancer patients;thus,parenteral and enteral nutrition support play important roles in cancer care.However,the impact of nonessential amino acid components of nutritional intake on cancer progression has not been fully studied.In this study,we discovered that gastrointestinal cancer patients who received cysteine as part of the parenteral nutrition had shorter overall survival(P<0.001)than those who did not.Cystine indeed robustly promotes colon cancer cell growth in vitro and in immunodeficient mice,predominately by inhibiting SESN2 transcription via the GCN2-ATF4 axis,resulting in mTORCl activation.mTORCl inhibitors Rapamycin and Everolimus block cystine-induced cancer cell proliferation.In addition,cystine confers resistance to oxaliplatin and irinotecan chemotherapy by quenching chemotherapy-induced reactive oxygen species via synthesizing glutathione.We demonstrated that dietary deprivation of cystine suppressed colon cancer xenograft growth without weight loss in mice and boosted the antitumor effect of oxaliplatin.These findings indicate that cyst(e)ine;as part of supplemental nutrition,plays an important role in colorectal cancer and manipulation of cyst(e)ine content in nutritional formulations may optimize colorectal cancer patient survival. | Jiao Wu Sai-Ching Jim Yeung Sicheng Liu Aiham Qdaisat Dewei Jiang Wenli Liu Zhuo Cheng Wenjing Liu Haixia Wang Lu Li Zhongmei Zhou Rong Liu Chuanyu Yang Ceshi Chen Runxiang Yang | 2021 | Signal Transduction and Targeted Therapy2021，6，6： | 2 |
| 10 | Arabidopsis ENOR3 regulates RNAi-mediated antiviral defense显示文摘Viruses can infect host plants to cause severe diseases and substantial agricultural loss, while plants have evolved RNA interference(RNAi) strategy to defend against viral infection. Despite enormous efforts, only a few host proteins in RNAi pathway were shown to mediate antiviral defense, including RNA-dependent RNA polymerase 1(RDR1), RDR6, DICER-LIKE 2(DCL2) and DCL4. In this study, we carried out a genetic screen for antiviral factors of RNAi pathway in Arabidopsis rdr6 background via inoculation with a 2 bdeficient Cucumber Mosaic Virus(CMV-D2b). We identified a mutant susceptible to CMV-D2b, referred to as enhancer of rdr6(enor) 3-1 rdr6, and found that ENOR3 encodes a functionally unknown protein with high homology to the mammalian Non Imprinted in Prader-Willi/Angelman(NIPA) magnesium transporters. ENOR3 inhibits accumulation of CMV-D2b and acts additively with RDR1, RDR6, DCL2 and DCL4 in antiviral defense. These results uncover that ENOR3 is a key component in antiviral RNAi pathway, and provide new insights into antiviral immunity. | Hua Gao Mai Yang Haitao Yang Yue Qin Biyun Zhu Gang Xu Chengyuan Xie Dewei Wu Xiaolin Zhang Wanxiang Li Jianbin Yan Susheng Song Tiancong Qi Shou-Wei Ding Daoxin Xie | 2018 | Journal of Genetics and Genomics2018，45，1： | 2 |
| 11 | Porous tantalum-composited gelatin nanoparticles hydrogel integrated with mesenchymal stem cell-derived endothelial cells to construct vascularized tissue in vivo显示文摘The ideal scaffold material of angiogenesis should have mechanical strength and provide appropriate physiological microporous structures to mimic the extracellular matrix environment.In this study,we constructed an integrated three-dimensional scaffold material using porous tantalum(pTa),gelatin nanoparticles(GNPs)hydrogel,and seeded with bone marrow mesenchymal stem cells(BMSCs)-derived endothelial cells(ECs)for vascular tissue engineering.The characteristics and biocompatibility of pTa and GNPs hydrogel were evaluated by mechanical testing,scanning electron microscopy,cell counting kit,and live-cell assay.The BMSCs-derived ECs were identified by flow cytometry and angiogenesis assay.BMSCs-derived ECs were seeded on the pTa-GNPs hydrogel scaffold and implanted subcutaneously in nude mice.Four weeks after the operation,the scaffold material was evaluated by histomorphology.The superior biocompatible ability of pTa-GNPs hydrogel scaffold was observed.Our in vivo results suggested that 28 days after implantation,the formation of the stable capillary-like network in scaffold material could be promoted significantly.The novel,integrated pTa-GNPs hydrogel scaffold is biocompatible with the host,and exhibits biomechanical and angiogenic properties.Moreover,combined with BMSCs-derived ECs,it could construct vascular engineered tissue in vivo.This study may provide a basis for applying pTa in bone regeneration and autologous BMSCs in tissue-engineered vascular grafts. | Zhenhua Zhao Mang Wang Fei Shao Ge Liu Junlei Li Xiaowei Wei Xiuzhi Zhang Jiahui Yang Fang Cao Qiushi Wang Huanan Wang Dewei Zhao | 2021 | Regenerative Biomaterials2021，8，6： | 2 |

| 13 | Non-metallic electronic regulation in CuCo oxy-/thio-spinel as advanced oxygen evolution electrocatalysts显示文摘Developing cost-effective and high-performance oxygen evolution reaction(OER)electrocatalysts has become the intense research on pursuing emerging renewable energy conversion,in which exploring and investigating the intrinsic nature of efficient and stable Cu Co spinel catalysts toward OER in alkaline media is highly desirable.Herein,Cu1–xCo2+xO4oxy-spinel nanoflakes are fabricated by a facile hydrothermal method with the oxidation of ammonia water.In the same condition,Cu1–xCo2+xS4thio-spinel nanospheres are formed without oxidation.In OER process,the as-obtained Cu1–xCo2+xO4nanoflakes and Cu1–xCo2+xS4nanospheres possess the anodic overpotential of 267 and 297 m V in alkaline media to drive the current density of 10 m A/cm^2,respectively,outperforming the state-of-the-art noble metal catalyst of RuO2.X-ray photoelectron spectroscopy analysis exhibits the higher ratio value of Co(Ⅲ)/Co(Ⅱ)in Cu1–xCo2+xO4than that in Cu1–xCo2+xS4,suggesting that the stronglyelectronegative oxygen efficiently predominates in regulating valence states of Co active sites in spinel structures.Remarkably,density functional theory simulation further reveals that the increased valence state of Co could accelerate the electron exchange between catalysts and oxygen adsorbates during electrocatalysis,thus contributing to the higher OER activity of Cu1–xCo2+xO4catalysts.This work provides deep insight regarding the significance of non-metal element(O and S)in Cu Co spinel structure catalysts,as well as presents a promising approach to exploit higher performance and grasp the mechanism of various non-noblemetal spinel catalysts for water oxidation. | Huan Yang Shuai Gao Dewei Rao Chaonan Zhang Xuecheng Zhou Shaokang Yang Jingjing Ye Shasha Yang Feili Lai Xiaohong Yan | 2021 | Science China Chemistry2021，64，1： | 1 |
