| 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 |

| 3 | Application of biomaterials for the repair and treatment of osteonecrosis of the femoral head显示文摘Osteonecrosis of the femoral head(ONFH)is one of the most common causes of hip disability in young adults.However,its cause and pathogenesis remain unclear,and might be caused by a variety of factors.ONFH mainly occurs in young adults.If not treated,70–80%of patients would progress into femoral head collapse in 3 years,and eventually require hip arthroplasty.Since these patients are younger and more physically active,multiple revision hip arthroplasty might be needed in their life.Repeated revision hip arthroplasty is difficult and risky,and has many complications,which inevitably affects the physical and mental health of patients.To delay the time of total hip arthroplasty for young adult patients with ONFH,biomaterials are used for its repair,which has a high clinical and social value for the retention of the patient’s own hip function.At present,there are many types of biomaterials used in repairing the femoral head,there is no uniform standard of use and the clinical effects are different.In this review,the main biomaterials used in the repair of ONFH are summarized and analyzed,and the prospects are also described. | Dewei Zhao Zhijie Ma | 2020 | Regenerative Biomaterials2020，7，1： | 8 |
| 4 | EphA2:A promising therapeutic target in breast cancer显示文摘Ephrin type-A receptor 2(EphA2),a receptor tyrosine kinase,is overexpressed in human breast cancers often linked to poor patient prognosis.Accumulating evidence demonstrates that EphA2 plays important roles in several critical processes associated with malignant breast progression,such as proliferation,survival,migration,invasion,drug resistance,metastasis,and angiogenesis.As its inhibition through multiple approaches can inhibit the growth of breast cancer and restore drug sensitivity,EphA2 has become a promising therapeutic target for breast cancer treatment.Here,we summarize the expression,functions,mechanisms of action,and regulation of EphA2 in breast cancer.We also list the potential therapeutic strategies targeting EphA2.Furthermore,we discuss the future directions of studying EphA2 in breast cancer. | Ping Zhao Dewei Jiang Yunchao Huang Ceshi Chen | 2021 | Journal of Genetics and Genomics2021，48，4： | 5 |
| 5 | 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 |
| 6 | Oxide-based cathode materials for rechargeable zinc ion batteries:Progresses and challenges显示文摘With the increasing demands for electrical energy storage technologies,rechargeable zinc ion batteries(ZIBs)have been rapidly developed in recent years owing to their high safety,low cost and high energy storage capability.The cathode is an essential part of ZIBs,which hosts zinc ions and determines the capacity,rate and cycling performance of the battery.The mainstream cathodes for ZIBs are oxidebased materials with tunnel,layer or 3 D crystal structures.In this review,we mainly focus on the latest advanced oxide-based cathode materials in ZIBs,including manganese oxides,vanadium oxides,spinel compounds,and other metal oxide based cathodes.In addition,the mechanisms of zinc storage and recent development in cathode design have been discussed in detail.Finally,current challenges and perspectives for the future research directions of oxide-based cathodes in ZIBs are presented. | Yingze Zhou Fandi Chen Hamidreza Arandiyan Peiyuan Guan Yunjian Liu Yuan Wang Chuan Zhao Danyang Wang Dewei Chu | 2021 | Journal of Energy Chemistry2021，30，6： | 4 |
| 7 | 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 |
| 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 | 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 |
| 10 | DFT study for combined influence of C-doping and external electric field on electronic structure and optical properties of TiO_(2)(001)surface显示文摘The electron structure and optical properties of C-TiO_(2)(001)surface under external electric field were studied by DFT method.After carbon doping,a new impurity level is introduced in the bandgap region of TiO_(2)(001)surface,and leads to the decrease of band gap,contributing to the shift of optical absorption to the visible region.When external electric field is applied across the C-TiO_(2)(001)surface,the band gap is further reduced with the increase of the electric field intensity from 0.1 eV to 0.5 eV.The electric field over 0.5 eV induces the electronic polarization.The spin-up bands show a gap,while spin-down electrons correspond to a metallic state.The energy gap of spin-up band decreases with increasing the electric field from 0.7 eV to 1.0 eV.The optical absorption of C-TiO_(2)(001)shifts to long wavelength compared with pure TiO_(2)(001).The electric filed make the optical absorption red-shift further,and the shift increases with an increase of the electric field,especially in the range of 0.7 eV-1.0 eV.The results show that the combined effect of carbon doping and electric field can enhance the photocatalytic activity of TiO_(2)(001)surface in visible region. | Cuihua Zhao Dewei Huang Jianhua Chen | 2018 | Journal of Materiomics2018，4，3： | 2 |
