| 1 | Significant Reduction of Interfacial Thermal Resistance and Phonon Scattering in Graphene/Polyimide Thermally Conductive Composite Films for Thermal Management显示文摘The developing flexible electronic equipment are greatly affected by the rapid accumulation of heat,which is urgent to be solved by thermally conductive polymer composite films.However,the interfacial thermal resistance(ITR)and the phonon scattering at the interfaces are the main bottlenecks limiting the rapid and efficient improvement of thermal conductivity coefficients(λ)of the polymer composite films.Moreover,few researches were focused on characterizing ITR and phonon scattering in thermally conductive polymer composite films.In this paper,graphene oxide(GO)was aminated(NH_(2)-GO)and reduced(NH_(2)-rGO),then NH_(2)-rGO/polyimide(NH_(2)-rGO/PI)thermally conductive composite films were fabricated.Raman spectroscopy was utilized to innovatively characterize phonon scattering and ITR at the interfaces in NH_(2)-rGO/PI thermally conductive composite films,revealing the interfacial thermal conduction mechanism,proving that the amination optimized the interfaces between NH_(2)-rGO and PI,reduced phonon scattering and ITR,and ultimately improved the interfacial thermal conduction.The in-planeλ(λ∥)and through-planeλ(λ_(⊥))of 15 wt%NH_(2)-rGO/PI thermally conductive composite films at room temperature were,respectively,7.13 W/mK and 0.74 W/mK,8.2 timesλ∥(0.87 W/mK)and 3.5 timesλ_(⊥)(0.21 W/mK)of pure PI film,also significantly higher thanλ∥(5.50 W/mK)andλ_(⊥)(0.62 W/mK)of 15 wt%rGO/PI thermally conductive composite films.Calculation based on the effective medium theory model proved that ITR was reduced via the amination of rGO.Infrared thermal imaging and finite element simulation showed that NH_(2)-rGO/PI thermally conductive composite films obtained excellent heat dissipation and efficient thermal management capabilities on the light-emitting diodes bulbs,5G high-power chips,and other electronic equipment,which are easy to generate heat severely. | Kunpeng Ruan Yongqiang Guo Chuyao Lu Xuetao Shi Tengbo Ma Yali Zhang Jie Kong Junwei Gu | 2021 | Research2021，，1： | 14 |
| 2 | Improvement of thermal conductivities and simulation model for glass fabrics reinforced epoxy laminated composites via introducing hetero-structured BNN-30@BNNS fillers显示文摘Hetero-structured thermally conductive spherical boron nitride and boron nitride nanosheets(BNN-30@BNNS)fillers were prepared via electro static self-assembly method.And the corresponding thermally conductive&electrically insulating BNN-30@BNNS/Si-GFs/E-44 laminated composites were then fabricated via hot compression.BNN-30@BNNS-Ⅲ(fBNN-30/fBNNS,1/2,wt/wt)fillers presented the optimal synergistic improvement effects on the thermal conductivities of epoxy composites.When the mass fraction of BNN-30@BNNS-Ⅲwas 15 wt%,λvalue of the BNN-30@BNNS-Ⅲ/E-44 composites was up to0.61 W m^(-1)K^(-1),increased by 2.8 times compared with pure E-44(λ=0.22 W m^(-1)K^(-1)),also higher than that of the 15 wt%BNN-30/E-44(0.56 W m^(-1)K^(-1)),15 wt%BNNS/E-44(0.42 W m^(-1)K^(-1)),and 15 wt%(BNN-30/BNNS)/E-44(direct blending BNN-30/BNNS hybrid fillers,1/2,wt/wt,0.49 W m^(-1)K^(-1))composites.Theλin-plane(λ//)andλcross-plane(λ_(⊥))of 15 wt%BNN-30@BNNS-Ⅲ/Si-GFs/E-44 laminated composites significantly reached 2.75 W m^(-1)K^(-1)and 1.32 W m^(-1)K^(-1),186.5%and 187.0%higher than those of Si-GFs/E-44 laminated composites(λ//=0.96 W m^(-1)K^(-1)andλ_(⊥)=0.46 W m^(-1)K^(-1)).Established models can well simulate heat transfer efficiency in the BNN-30@BNNS-Ⅲ/Si-GFs/E-44 laminated composites.Under the condition of point heat source,the introduction of BNN-30@BNNS-Ⅲfillers were conducive to accelerating heat flow trans fe r.BNN-30@BNNS-Ⅲ/Si-GFs/E-44 laminated composites also demonstrated outstanding electrical insulating properties(cross-plane withstanding voltage,breakdown strength,surface&volume resistivity of 51.3 kV,23.8 kV mm^(-1),3.7×10^(14)Ω&3.4×10^(14)Ω·cm,favorable mechanical properties(flexural strength of 401.0 MPa and ILSS of 22.3 MPa),excellent dielectric properties(εof 4.92 and tanδof 0.008)and terrific thermal properties(T_(g )of 167.3℃and T_(HRI) of 199.2℃). | Xuetao Shi Ruihan Zhang Kunpeng Ruan Tengbo Ma Yongqiang Guo Junwei Gu | 2021 | Journal of Materials Science & Technology2021，，23： | 8 |
| 3 | Chromosome-scale assembly of the Dendrobium chrysotoxum genome enhances the understanding of orchid evolution显示文摘As one of the largest families of angiosperms,the Orchidaceae family is diverse.Dendrobium represents the second largest genus of the Orchidaceae.However,an assembled high-quality genome of species in this genus is lacking.Here,we report a chromosome-scale reference genome of Dendrobium chrysotoxum,an important ornamental and medicinal orchid species.The assembled genome size of D.chrysotoxum was 1.37 Gb,with a contig N50 value of 1.54 Mb.Of the sequences,95.75%were anchored to 19 pseudochromosomes.There were 30,044 genes predicted in the D.chrysotoxum genome.Two whole-genome polyploidization events occurred in D.chrysotoxum.In terms of the second event,whole-genome duplication(WGD)was also found to have occurred in other Orchidaceae members,which diverged mainly via gene loss immediately after the WGD event occurred;the first duplication was found to have occurred in most monocots(tau event).We identified sugar transporter(SWEET)gene family expansion,which might be related to the abundant medicinal compounds and fleshy stems of D.chrysotoxum.MADS-box genes were identified in D.chrysotoxum,as well as members of TPS and Hsp90 gene families,which are associated with resistance,which may contribute to the adaptive evolution of orchids.We also investigated the interplay among carotenoid,ABA,and ethylene biosynthesis in D.chrysotoxum to elucidate the regulatory mechanisms of the short flowering period of orchids with yellow flowers.The reference D.chrysotoxum genome will provide important insights for further research on medicinal active ingredients and breeding and enhances the understanding of orchid evolution. | Yongxia Zhang Guo-Qiang Zhang Diyang Zhang Xue-Die Liu Xin-Yu Xu Wei-Hong Sun Xia Yu Xiaoen Zhu Zhi-Wen Wang Xiang Zhao Wen-Ying Zhong Hongfeng Chen Wei-Lun Yin Tengbo Huang Shan-Ce Niu Zhong-Jian Liu | 2021 | Horticulture Research2021，8，1： | 3 |

| 5 | Identification of Glutaminyl Cyclase isoenzyme isoQC as a regulator of SIRPα-CD47 axis显示文摘Dear Editor,Cancer cells often upregulate the expression of ligands for the inhibitory immune checkpoints receptor to escape anti-tumor immunity1. Targeting inhibitory immune checkpoints has become one of the most promising anticancer therapeutic inventions. Infiltration of myeloid cells, especially phagocytic cells, to tumors is often associated with chemotherapy resistance and progression of various cancer types. Phagocytosis of cancer cells is the major mechanism for these myeloid cells-mediated antitumor activity. However, many types of cancer cells express high level of ‘don’t eat me’ signals on the cell surface to escape the phagocytic cells-mediated antitumor immunity. | Zhiqiang Wu Linjun Weng Tengbo Zhang Hongling Tian Lan Fang Hongqi Teng Wen Zhang Jing Gao Yun Hao Yaxu Li Hu Zhou Ping Wang | 2019 | Cell Research2019，29，6： | 1 |

| 8 | Switching the coordination geometry to enhance erbium(Ⅲ)single-molecule magnets显示文摘Two erbium(Ⅲ)complexes[ErCl(OAr^(Ad))_(3)][Na(THF)_(6)](1)and Er(OAr^(Ad))_(3)(2)are successfully prepared by using one variety of'hard'base ligand with large steric hindrance.The coordination geometry around the Er(Ⅲ)site changes from distorted tetrahedral to flat trigonal pyramid geometry in different solvent environment due to the removal of the coordinated chloride.Such an alternation significantly enhances the single-molecule magnet(SMM)behavior and makes the field-induced effective energy barrier(Ueff)arrive at 43(1)cm-1for the latter.Together with theoretical calculations,this study shows that strong equatorial ligand field and high local symmetry are critical to suppress the quantum tunneling of the magnetization(QTM)and achieve high-performance erbium(Ⅲ)based SMMs. | Qian-Cheng Luo Ning Ge Yuan-Qi Zhai Tengbo Wang Lin Sun Qi Sun Fanni Li Zhendong Fu Yan-Zhen Zheng | 2023 | Chinese Chemical Letters2023，34，5： | 0 |
| 9 | Photothermal‑Triggered Structural Change of Nanofiber Scaffold Integrating with Graded Mineralization to Promote Tendon–Bone Healing显示文摘Scaffolds functionalized with graded changes in both fiber alignment and mineral content are more appealing for tendon-bone healing.This study reports the healing of rotator cuff injury using a heterogeneous nanofiber scaffold,which is associated with a structural gradating from aligned to random and an increasing gradient of mineral content in the same orientation.The photothermal-triggered structural change of a nanofiber scaffold followed by graded mineralization is key to constructing such scaffolds.This type of scaffold was found to be biocompatible and provide beneficial contact guidance in the manipulation of tendon-derived stem cell morphologies in vitro.Specifically,tenogenic and osteogenic differentiation of tendon-derived stem cells were simultaneously achieved using the fabricated scaffold.In vivo investigation also showed the improved healing of rabbit rotator cuff injuries based on immunohistochemical analysis and biomechanical investigation that indicates the promising potential of a dual-gradient nanofiber scaffold in clinical tendon-bone healing. | Chenghao Yu Tianrui Wang Hongcui Diao Na Liu Yi Zhang Hongyuan Jiang Peng Zhao Zhengyi Shan Zewen Sun Tong Wu Xiumei Mo Tengbo Yu | 2022 | Advanced Fiber Materials2022，4，4： | 0 |
