| 1 | A New Way of Strengthening and Toughening for Carbon Fiber Reinforced Polyphenylene Sulfide(CF/PPS) Composites via Matrix Modification显示文摘The effect of pressure-induced flow(PIF) processing on the mechanical properties of noncontinuous carbon fiber(CF) reinforced polyphenylene sulfide(PPS) composites was investigated. A series of CF/PPS composites under different processing conditions were prepared through PIF-processing. SEM observations showed that the interfaces adhesion between CFs and PPS became stronger and ductile fracture mainly occurred in PPS matrix. This brought to a great increase of both strength and toughness by about 2 folds, when the composites were processed at 240 ℃ and under 263 MPa. The results in differential scanning calorimetry(DSC) and X-ray diffraction(XRD) measurements indicated more regular crystalline structures and orientation of lamellae formed during PIF-processing. | 徐英凯 朱姝 ZHANG Zhao YU Muhuo YUAN Xiangkai | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，6： | 2 |

| 5 | NAT 10 promotes gastric cancer metastasis via N4-acetylated COL5A1显示文摘Dear Editor,Gastric cancer(GC)is among the most prevalent gastrointestinal malignancies.The occurrence of local deep infiltration or distant metastasis in GC is commonly associated with weak treatment and poor prognosis.1 Although,N4-Acetylcytidine(ac4C)represents one of the extensive chemical modifications in mRNAs that plays a pivotal role in modulating mRNA stability and the mRNA translation process(Fig.1b). | Yigan Zhang Yuanxue Jinq Yinxue Wanq Jianming Tang Xiaoran Zhu Wei-Lin Jin Yiqing Wang Wenzhen Yuan Xiangkai Li Xun Li | 2021 | Signal Transduction and Targeted Therapy2021，6，6： | 1 |
| 6 | Bidirectional differentiation of BMSCs induced by a biomimetic procallus based on a gelatin-reduced graphene oxide reinforced hydrogel for rapid bone regeneration显示文摘Developmental engineering strategy needs the biomimetic composites that can integrate the progenitor cells,biomaterial matrices and bioactive signals to mimic the natural bone healing process for faster healing and reconstruction of segmental bone defects.We prepared the gelatin-reduced graphene oxide(GOG)and constructed the composites that mimicked the procallus by combining the GOG with the photo-crosslinked gelatin hydrogel.The biological effects of the GOG-reinforced composites could induce the bi-differentiation of bone marrow stromal cells(BMSCs)for rapid bone repair.The proper ratio of GOG in the composites regulated the composites’mechanical properties to a suitable range for the adhesion and proliferation of BMSCs.Besides,the GOG-mediated bidirectional differentiation of BMSCs,including osteogenesis and angiogenesis,could be activated through Erk1/2 and AKT pathway.The methyl vanillate(MV)delivered by GOG also contributed to the bioactive signals of the biomimetic procallus through priming the osteogenesis of BMSCs.During the repair of the calvarial defect in vivo,the initial hypoxic condition due to GOG in the composites gradually transformed into a well-vasculature robust situation with the bi-differentiation of BMSCs,which mimicked the process of bone healing resulting in the rapid bone regeneration.As an inorganic constituent,GOG reinforced the organic photo-crosslinked gelatin hydrogel to form a double-phase biomimetic procallus,which provided the porous extracellular matrix microenvironment and bioactive signals for the bi-directional differentiation of BMSCs.These show a promised application of the bio-reduced graphene oxide in biomedicine with a developmental engineering strategy. | Delong Jiao Ao Zheng Yang Liu Xiangkai Zhang Xiao Wang Jiannan Wu Wenjun She Kaige Lv Lingyan Cao Xinquan Jiang | 2021 | Bioactive Materials2021，6，7： | 1 |
| 7 | Drought stress and plant ecotype drive microbiome recruitment in switchgrass rhizosheath显示文摘The rhizosheath,a layer of soil grains that adheres firmly to roots,is beneficial for plant growth and adaptation to drought environments.Switchgrass is a perennial C4 grass which can form contact rhizosheath under drought conditions.In this study,we characterized the microbiomes of four different rhizocompartments of two switchgrass ecotypes(Alamo and Kanlow)grown under drought or well-watered conditions via 16S ribosomal RNA amplicon sequencing.These four rhizocompartments,the bulk soil,rhizosheath soil,rhizoplane,and root endosphere,harbored both distinct and overlapping microbial communities.The root compartments(rhizoplane and root endosphere)displayed low-complexity communities dominated by Proteobacteria and Firmicutes.Compared to bulk soil,Cyanobacteria and Bacteroidetes were selectively enriched,while Proteobacteria and Firmicutes were selectively depleted,in rhizosheath soil.Taxa from Proteobacteria or Firmicutes were specifically selected in Alamo or Kanlow rhizosheath soil.Following drought stress,Citrobacter and Acinetobacter were further enriched in rhizosheath soil,suggesting that rhizosheath microbiome assembly is driven by drought stress.Additionally,the ecotype-specific recruitment of rhizosheath microbiome reveals their differences in drought stress responses.Collectively,these results shed light on rhizosheath microbiome recruitment in switchgrass and lay the foundation for the improvement of drought tolerance in switchgrass by regulating the rhizosheath microbiome. | Tie-Yuan Liu Nenghui Ye Xinyu Wang Debatosh Das Yuxiang Tan Xiangkai You Mingxiu Long Tianming Hu Lei Dai Jianhua Zhang Mo-Xian Chen | 2021 | Journal of Integrative Plant Biology2021，63，10： | 1 |

| 13 | Nanofibrils in 3D aligned channel arrays with synergistic effect of Ag/NPs for rapid and highly efficient electric field disinfection显示文摘The disinfection of waterborne pathogens from drinking water is extremely important for human health.Although countless efforts have been devoted for drinking water inactivation,challenges still exist in terms of relative high energy consumption and complicated to implement and maintain.Here,silver nanoparticles anchoring wood carbon(Ag NPs/WC)membrane is developed as cost-effective,high flux,scalable filter for highly efficient electric field disinfection of water.Under electric field of 4 V voltage,the designed membrane achieved more than 5 log(99.999%)disinfection performance for different model bacteria,including Escherichia coli(E.coli),Enterococcus faecalis(E.faecalis),Salmonella enterica serovar Typhimirium(S.Typhimurium)and Bacillus subtilis(B.subtilis)with a high flux of 3.8 x 103 L m^(-2)h^(-1),extremely low energy consumption of 2 J L^(-1)m^(-2)and fantastic durability(7 days).The high disinfection performance of Ag NPs/WC membrane is attributed to the synergistic disinfection of carbon nanofibrils,Ag nanoparticles as well as the low tortuous structure of the channels in wood carbon.The Ag NPs/WC membrane presents a promising strategy for point-of-use drinking water electric field disinfection treatment. | Zi Yang Hongyuhang Ni Pu Liu Hanwen Liu Ke Yang Zhengze Zhang Baodui Wang Xiangkai Li Fengjuan Chen | 2021 | Chinese Chemical Letters2021，32，10： | 0 |
| 14 | Co_(3)O_(4) with ordered pore structure derived from wood vessels for efficient Hg^(0) oxidation显示文摘Catalytic oxidation of Hgo to Hg~O is an efficient way to remove Hg^(0) from coal-fired flue gas.The catalyst with ordered pore structure can lower mass transfer resistance resulting in higher Hg^(0) oxidation efficiency.Therefore,in the present work,wood vessels were used as sacrificial template to obtain Co_(3)O_(4) with ordered pore structure.SEM and BET results show that,when the mass concentrations of Co(NO_(3))_(2)·6H_(2)O was 20%,the obtained catalyst(Co_(3)O_(4) [20%Co(NO_(3))_(2)])possesses better pore structure and higher surface area.It will expose more available surface active sites and lower the mass transfer resistance.Furthermore,XPS results prove that Co_(3)O_(4) [20%Co(NO_(3))_(2)]has the highest ratio of chemisorbed oxygen which plays an important role in Hg^(0) oxidation process.These results lead to a better Hg^(0) oxidation efficiency of Co_(3)O_(4) [20%Co(NO_(3))_(2)],which is about 90%in the temperature range of 200 to 350℃,Furthermore,Co_(3)O_(4) [20%Co(NO_(3))_(2)]has a stable catalytic activity,and its Hg^(0) oxidation efficiency maintains above 90%at 250℃even after 90 h test,A probable reaction mechanism is deduced by the XPS results of the fresh,used and regenerated catalyst of Co_(3)O_(4) [20%Co(NO3)2].Chemisorbed oxygen can react with Hg^(0) forming HgO with the reduction of Co^(3+)to Co^(2)+.And lattice oxygen and gaseous oxygen can supplement the consumption of chemisorbed oxygen to oxidize Co^(2+)to Co^(3+). | Xiaopeng Zhang Cheng Gao Ziwei Wang Ximiao Wang Jie Cheng Xinxin Song Xiangkai Han Ning Zhang Junjiang Bao Gaohong He | 2022 | Chinese Journal of Chemical Engineering2022，，10： | 0 |
| 15 | Multifunctionalized carbon-fiber-reinforced polyetheretherketone implant for rapid osseointegration under infected environment显示文摘Carbon fiber reinforced polyetheretherketone(CFRPEEK)possesses a similar elastic modulus to that of human cortical bone and is considered as a promising candidate to replace metallic implants.However,the bioinertness and deficiency of antibacterial activities impede its application in orthopedic and dentistry.In this work,titanium plasma immersion ion implantation(Ti-PⅢ)is applied to modify CFRPEEK,achieving unique multi-hierarchical nanostructures and active sites on the surface.Then,hybrid polydopamine(PDA)@ZnO-EDN1 nanoparticles(NPs)are introduced to construct versatile surfaces with improved osteogenic and angiogenic properties and excellent antibacterial properties.Our study established that the modified CFRPEEK presented favorable stability and cytocompatibility.Compared with bare CFRPEEK,improved osteogenic differentiation of rat mesenchymal stem cells(BMSCs)and vascularization of human umbilical vein endothelial cells(HUVECs)are found on the functionalized surface due to the zinc ions and EDN1 releasing.In vitro bacteriostasis assay confirms that hybrid PDA@ZnO NPs on the functionalized surface provided an effective antibacterial effect.Moreover,the rat infected model corroborates the enhanced antibiosis and osteointegration of the functionalized CFRPEEK.Our findings indicate that the multilevel nanostructured PDA@ZnO-EDN1 coated CFRPEEK with enhanced antibacterial,angiogenic,and osteogenic capacity has great potential as an orthopedic/dental implant material for clinical application. | Xiao Wang Lisha Pan Ao Zheng Lingyan Cao Jin Wen Tingshu Su Xiangkai Zhang Qingfeng Huang Xinquan Jiang | 2023 | Bioactive Materials2023，，6： | 0 |
