| 1 | Generalized non-linear strength theory and transformed stress space显示文摘Based on the test data of frictional materials and previous research achievements in this field, a generalized non-linear strength theory (GNST) is proposed. It describes non-linear strength properties on the π-plane and the meridian plane using a unified formula, and it includes almost all the present non-linear strength theories, which can be used in just one material. The shape of failure function of the GNST is a smooth curve between the SMP criterion and the Mises criterion on the π-plane, and an exponential curve on the meridian plane. Through the transformed stress space based on the GNST, the combination of the GNST and various constitutive models using p and q as stress parameters can be realized simply and rationally in three-dimensional stress state. | YAO Yangping LU Dechun ZHOU Annan ZOU Bo | 2004 | Science China(Technological Sciences)2004，47，6： | 57 |

| 3 | Engineering Broad-Spectrum Bacterial Blight Resistance by Simultaneously Disrupting Variable TALE-Binding Elements of Multiple Susceptibility Genes in Rice显示文摘Xanthomonas oryzae pv.oryzae(Xoo),the causal agent of bacterial blight of rice,employs the transcription activator-like effectors(TALEs)to induce the expression of the OsSWEET family of putative sugar transporter genes,which function in conferring disease susceptibility(S)in rice plants.To engineer broadspectrum bacterial blight resistance,we used CRISPR/Cas9-mediated gene editing to disrupt the TALEbinding elements(EBEs)of two S genes,OsSWEETH and OsSWEET14,in rice cv.Kitaake,which harbors the recessive resistance allele of Xa25/OsSWEET13.The engineered rice line MS14K exhibited broadspectrum resistance to most Xoo strains with a few exceptions,suggesting that the compatible strains may contain new TALEs.We identified two PthXo2-like TALEs,Tal5LN18 and Tal7PX061,as major virulence factors in the compatible Xoo strains LN18 and PX061,respectively,and found that Xoo encodes at least five types of PthXo2-like effectors.Given that PthXo2/PthXo2.1 target OsSlVEETf3 for transcriptional activation,the genomes of 3000 rice varieties were analyzed for EBE variationsin the OsSWEET13 promoter,and 10Xa25-like haplotypes were identified.We found that Tal5LN18 and Tal7PX〇6i bind slightly different EBE sequences in the OsSWEET13 promoter to activate its expression.CRISPR/Cas9 technology was then used to generate InDels in the EBE of the OsSWEET13 promoter in MS14K to creat a new germplasm with three edited OsSWEET EBEs and broad-spectrum resistance against all Xoo strains tested.Collectively,our findings illustrate how to disarm TALE-S co-evolved loci to generate broad-spectrum resistance through the loss of effector-triggered susceptibility in plants. | Zhengyin Xu Xiameng Xu Qiang Gong Ziyang Li Ying Li Sai Wang Yangyang Yang Wenxiu Ma Longyu Liu Bo Zhu Lifang Zou Gongyou Chen | 2019 | Molecular Plant2019，12，11： | 29 |
| 4 | Overexpression of B7-H3 augments anti-apoptosis of colorectal cancer cells by Jak2-STAT3显示文摘AIM:To investigate the role of the overexpression of B7-H3 in apoptosis in colorectal cancer cell lines and the underlying molecular mechanisms.METHODS:SW620 cells that highly overexpressed B7-H3(SW620-B7-H3-EGFP)and HCT8 cells stably transfected with B7-H3 sh RNA(HCT8-sh B7-H3)were previously constructed in our laboratory.Cells transfected with p IRES2-EGFP were used as negative controls(SW620-NC and HCT8-NC).Real-time PCR and western blotting analysis were used to detect the m RNA and protein expressions of the apoptosis regulator proteins Bcl-2,Bcl-xl and Bax.A cell proliferation assay was used to evaluate the survival rate and drug sensitivity of the cells.The effect of drug resistance was detected by a cell cycle assay.Active caspase-3western blotting was used to reflect the anti-apoptotic ability of cells.Western blotting was also performed to determine the expression of proteins associated with the Jak2-STAT3 signaling pathway and the apoptosis regulator proteins after the treatment with AG490,a Jak2 specific inhibitor,in B7-H3 overexpressing cells.The data were analyzed by Graph Pad Prism 6 using a non-paired t-test.RESULTS:Whether by overexpression in SW620cells or downregulation in HCT8,B7-H3 significantly affected the expression of anti-and pro-apoptotic proteins,at both the transcriptional and translational levels,compared with the negative control(P<0.05).A cell proliferation assay revealed that B7-H3overexpression increased the drug resistance of cells and resulted in a higher survival rate(P<0.05).In addition,the results of cell cycle and active caspase-3western blotting proved that B7-H3 overexpression inhibited apoptosis in colorectal cancer cell lines(P<0.05).B7-H3 overexpression improved Jak2 and STAT3phosphorylation and,in turn,increased the expression of the downstream anti-apoptotic proteins B-cell CLL/lymphoma 2(Bcl-2)and Bcl-xl,based on western blotting(P<0.05).After treating B7-H3 overexpressing cells with the Jak2-specific inhibitor AG490,the phosphorylation of Jak2 and STAT3,and the expression of Bcl-2 and Bcl-xl,decreased accordingly(P<0.05).This finding suggested that the Jak2-STAT3 pathway is involved in the mechanism mediating the anti-apoptotic ability of B7-H3.CONCLUSION:The overexpression of B7-H3 induces resistance to apoptosis in colorectal cancer cell lines by upregulating the Jak2-STAT3 signaling pathway,potentially providing new approaches to the treatment of colorectal cancer. | Ting Zhang Bo Jiang Shi-Tao Zou Fen Liu Dong Hua | 2015 | World Journal of Gastroenterology2015，21，6： | 21 |
| 5 | High-speed femtosecond laser plasmonic lithography and reduction of graphene oxide for anisotropic photoresponse显示文摘Micro/nanoprocessing of graphene surfaces has attracted significant interest for both science and applications due to its effective modulation of material properties,which,however,is usually restricted by the disadvantages of the current fabrication methods.Here,by exploiting cylindrical focusing of a femtosecond laser on graphene oxide(GO)films,we successfully produce uniform subwavelength grating structures at high speed along with a simultaneous in situ photoreduction process.Strikingly,the well-defined structures feature orientations parallel to the laser polarization and significant robustness against distinct perturbations.The proposed model and simulations reveal that the structure formation is based on the transverse electric(TE)surface plasmons triggered by the gradient reduction of the GO film from its surface to the interior,which eventually results in interference intensity fringes and spatially periodic interactions.Further experiments prove that such a regular structured surface can cause enhanced optical absorption(>20%)and an anisotropic photoresponse(~0.46 ratio)for the reduced GO film.Our work not only provides new insights into understanding the laser-GO interaction but also lays a solid foundation for practical usage of femtosecond laser plasmonic lithography,with the prospect of expansion to other two-dimensional materials for novel device applications. | Tingting Zou Bo Zhao Wei Xin Ye Wang Bin Wang Xin Zheng Hongbo Xie Zhiyu Zhang Jianjun Yang Chunlei Guo | 2020 | Light(Science & Applications)2020，9，1： | 17 |
| 6 | Fe2N nanoparticles boosting FeNx moieties for highly efficient oxygen reduction reaction in Fe-N-C porous catalyst显示文摘Replacing Pt-based electrocatalysts for the oxygen reduction reaction (ORR) with high performance and low-cost non-precious metal catalysts is crucial for the commercialization of fuel cells.Herein,we present a highly efficient Fe-N-C porous ORR electrocatalyst with FeNx moieties promoted by Fe2N nanoparticles derived from Fe-doped zeolitic imidazolate framework.The best-performing Fe-N-C/HPC-NH3 catalyst exhibits a superior ORR activity with an onset (E0) and half-wave (E1/2) potential of 0.945 and 0.803 V (RHE),respectively,which is comparable to those of the commercial Pt/C in acidic media.Probing and acid-leaching experiments prove that FeNx moieties play an important role in the ORR and the Fe2N can further improve the ORR activity.Density functional theory calculation reveals a synergistic effect that the existence of Fe2N weakens the adsorption of ORR intermediates on active sites and lowers the reaction free energy of the potential limiting step,thus facilitating the ORR.Both experimental evidence and theoretical analysis for the enhancement of ORR activity by Fe2N decoration in Fe-N-C catalyst might inspire a new strategy for rational design of high performance non-precious metal catalysts. | Xiao Liu Hong Liu Chi Chen Liangliang Zou Yuan Li Qing Zhang Bo Yang Zhiqing Zou Hui Yang | 2019 | Nano Research2019，12，7： | 14 |
| 7 | End-stage liver disease score and future liver remnant volume predict post-hepatectomy liver failure in hepatocellular carcinoma显示文摘BACKGROUND Hepatocellular carcinoma(HCC)is the world’s sixth most common malignant tumor and the third cause of cancer death.Although great progress has been made in hepatectomy,it is still associated with a certain degree of risk of posthepatectomy liver failure(PHLF),which extends the length of hospital stay and remains the leading cause of postoperative death.Studies have shown that assessment of hepatic functional reserve before hepatectomy is beneficial for reducing the incidence of PHLF.AIM To assess the value of model for end-stage liver disease(MELD)score combined with standardized future liver remnant(sFLR)volume in predicting PHLF in patients undergoing hepatectomy for HCC.METHODS This study was attended by 238 patients with HCC who underwent hepatectomy between January 2015 and January 2018.Discrimination of sFLR volume,MELD score,and sFLR/MELD ratio to predict PHLF was evaluated according to the area under the receiver operating characteristic curve.RESULTS The patients were divided into two groups according to whether PHLF occurred after hepatectomy.The incidence of PHLF was 8.4%in our research.The incidence of PHLF increased with the decrease in sFLR volume and the increase in MELD score.Both sFLR volume and MELD score were considered independent predictive factors for PHLF.Moreover,the cut-off value of the sFLR/MELD score to predict PHLF was 0.078(P<0.001).This suggests that an sFLR/MELD≥0.078 indicates a higher incidence of PHLF than an sFLR/MELD<0.078.CONCLUSION MELD combined with sFLR is a reliable and effective PHLF predictor,which is superior to MELD score or sFLR volume alone. | Fan-Hua Kong Xiong-Ying Miao Heng Zou Li Xiong Yu Wen Bo Chen Xi Liu Jiang-Jiao Zhou | 2019 | World Journal of Clinical Cases2019，7，22： | 14 |

| 9 | Ciliary parathyroid hormone signaling activates transforming growth factor-βto maintain intervertebral disc homeostasis during aging显示文摘Degenerative disc disease(DDD) is associated with intervertebral disc degeneration of spinal instability. Here, we report that the cilia of nucleus pulposus(NP) cells mediate mechanotransduction to maintain anabolic activity in the discs. We found that mechanical stress promotes transport of parathyroid hormone 1 receptor(PTH1 R) to the cilia and enhances parathyroid hormone(PTH) signaling in NP cells. PTH induces transcription of integrin α_vβ_6 to activate the transforming growth factor(TGF)-β-connective tissue growth factor(CCN2)-matrix proteins signaling cascade. Intermittent injection of PTH(iPTH) effectively attenuates disc degeneration of aged mice by direct signaling through NP cells, specifically improving intervertebral disc height and volume by increasing levels of TGF-β activity, CCN2, and aggrecan. PTH1 R is expressed in both mouse and human NP cells. Importantly,knockout PTH1 R or cilia in the NP cells results in significant disc degeneration and blunts the effect of PTH on attenuation of aged discs. Thus, mechanical stress-induced transport of PTH1 R to the cilia enhances PTH signaling, which helps maintain intervertebral disc homeostasis, particularly during aging, indicating therapeutic potential of iPTH for DDD. | Liwei Zheng Yong Cao Shuangfei Ni Huabin Qi Zemin Ling Xin Xu Xuenong Zou Tianding Wu Ruoxian Deng Bo Hu Bo Gao Hao Chen Yusheng Li Jianxi Zhu Francis Tintani Shadpour Demehri Amit Jain Khaled M.Kebaish Shenghui Liao Cheryle A.Séguin Janet L.Crane Mei Wan Hongbin Lu Paul D.Sponseller Lee H.RileyIII Xuedong Zhou Jianzhong Hu Xu Cao | 2018 | Bone Research2018，6，3： | 13 |
| 10 | A Novel RT-LAMP Assay for Rapid and Simple Detection of Classical Swine Fever Virus显示文摘A simple and rapid assay for the detection of Classical swine fever virus(CSFV)was established using reverse transcription loop-mediated isothermal amplification(RT-LAMP).This study describes the amplification of the genomic RNA of CSFV under isothermal conditions(63℃)within one hour,using a set of six primers(two outer primers,two inner primers and two loop primers).This RT-LAMP assay showed 100-fold higher sensitivity than the standard RT-PCR method and identified eighteen additional positive cases that were negative when tested by RT-PCR.This RT-LAMP was able to detect all the 13 strains of CSFV but not the BVDV.PRRSV.SIV. PRV-PCV,thus showed a good specificity.Products amplified by RT-LAMP can be visualized by agarose gel electrophoresis and in addition,either as a white precipitate at the bottom of the tube after a pulse spin or as a color change when dyed with SYBR Green I which are visible to the naked eye.Because RT-LAMP is low-cost and produces rapid results,it has the potential to be an excellent tool for CSFV surveillance in the field,especially in developing countries. | Lei CHEN Xue-zheng FAN Qin WANG Lu XU Qi-zu ZHAO Yuan-chen ZHOU Jun LIU Bo TANG Xing-qi ZOU | 2010 | Virologica Sinica2010，25，1： | 12 |

| 12 | Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event. | TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，3： | 12 |
| 13 | Design and performance analysis of orthogonal coding signal in MIMO-SAR显示文摘Multi-input multi-output (MIMO) radar which has evident advantages in many applications is a new radar system.Applying the MIMO technique to the earth observing synthetic aperture radar (SAR) system offers effective ways for the improvement of high resolution and wide swath imaging and ground moving target indication (GMTI) systems.Designing the optimal orthogonal waveform is a crucial problem in the research on MIMO radar.First,the index definition of synthetic integrated side-lobe level ratio (ISLR) is proposed by focusing on the SAR application and considering the cross-correlation energy influences between orthogonal coding signals with the same frequency band.Second,it is theoretically demonstrated that the performance of synthetic ISLR of orthogonal coding signals with the same frequency band cannot meet the demands of SAR imaging,which has been proved by one-dimensional numerical simulation. Third,it has been shown through numerical simulation that the performance of synthetic ISLR of orthogonal coding signals still cannot be improved by dealing with the mismatched filtering.Finally,a set of orthogonal phase coding signals are designed for multiple MIMO-SAR antennas.The conclusions are verified through MIMO-SAR imaging and InSAR simulation experiments. | ZOU Bo DONG Zhen LIANG DianNong | 2011 | Science China(Information Sciences)2011，54，8： | 11 |

| 15 | R-CHOP regimen can significantly decrease the risk of disease relapse and progression in patients with non-germinal centerB-cell subtype diffuse large B-cell lymphoma显示文摘To further explore the role of rituximab when added to the CHOP-like regimen in the treatment of immunohistochemically defined non-germinal center B-cell subtype (non-GCB) diffuse large B-celllymphoma (DLBCL), 159 newly diagnosed DLBCL patients were studied retrospectively based on the immunohistochemical evaluation of CD10, Bcl-6, MUM-1, and Bcl-2. Altogether, 110 patients underwent the CHOP-like regimen, and rituximab was added for the other 49 patients. Cox regression analysis showed that compared with the CHOP-like regimen, the rituximab-based regimen (R-CHOP regimen)significantly decreased the risk of disease relapse and progression in CD10-negative patients (P=0.001),Bcl-6-negative patients (P=0.01), and MUM-1-positive patients (P=0.003). The risk of disease relapse in patients with non-GCB subtype (P=0.002) also decreased. In contrast, patients with the opposite immunohistochemical marker expression profile and GCB subtype did not benefit from treatment with the R-CHOP regimen. In addition, non-GCB subtype patients had a significantly higher expression rate of Bcl-2 than GCB subtype patients (P=0.042). Although univariate analysis found that both Bcl-2-positive and-negative patients had significantly higher event-free survival rates with the R-CHOP regimen, only Bcl-2 positivity (P=0.004) maintained significance in the Cox regression analysis. We conclude that the addition of rituximab can significantly improve the prognosis of patients with non-GCB subtype DLBCL, which is closely related to the expression of CD10, Bcl-6, MUM-1, and Bcl-2. | Xiao-Hui He Bo Li Sheng Yang Ning Lu Xun Zhang Shuang-Mei Zou Ye-Xiong Li Yong-Wen Song Shan Zheng Mei Dong Sheng-Yu Zhou dian-Liang Yang Peng Liu Chang-Gong Zhang Yan Qin Feng-Yi Feng Yuan-Kai Shi | 2012 | Chinese Journal of Cancer2012，31，6： | 9 |
| 16 | Highly expressed BMP9/GDF2 in postnatal mouse liver and lungs may account for its pleiotropic effects on stem cell differentiation,angiogenesis,tumor growth and metabolism显示文摘Bone morphogenetic protein 9(BMP9)(or GDF2)was originally identified from fetal mouse liver cDNA libraries.Emerging evidence indicates BMP9 exerts diverse and pleiotropic functions during postnatal development and in maintaining tissue homeostasis.However,the expression landscape of BMP9 signaling during development and/or in adult tissues remains to be analyzed.Here,we conducted a comprehensive analysis of the expression landscape of BMP9 and its signaling mediators in postnatal mice.By analyzing mouse ENCODE transcriptome datasets we found Bmp9 was highly expressed in the liver and detectable in embryonic brain,adult lungs and adult placenta.We next conducted a comprehensive qPCR analysis of RNAs isolated from major mouse tissues/organs at various ages.We found that Bmp9 was highly expressed in the liver and lung tissues of young adult mice,but decreased in older mice.Interestingly,Bmp9 was only expressed at low to modest levels in developing bones.BMP9-associated TGFβ/BMPR type I receptor Alk1 was highly expressed in the adult lungs.Furthermore,the feedback inhibitor Smads Smad6 and Smad7 were widely expressed in mouse postnatal tissues.However,the BMP signaling antagonist noggin was highly expressed in fat and heart in the older age groups,as well as in kidney,liver and lungs in a biphasic fashion.Thus,our findings indicate that the circulating BMP9 produced in liver and lungs may account for its pleiotropic effects on postnatal tissues/organs although possible roles of BMP9 signaling in liver and lungs remain to be fully understood. | Wei Liu Zhongliang Deng Zongyue Zeng Jiaming Fan Yixiao Feng Xi Wang Daigui Cao Bo Zhang Lijuan Yang Bin Liu Mikhail Pakvasa William Wagstaff Xiaoxing Wu Huaxiu Luo Jing Zhang Meng Zhang Fang He Yukun Mao Huiming Ding Yongtao Zhang Changchun Niu Rex C.Haydon Hue H.Luu Jennifer Moriatis Wolf Michael J.Lee Wei Huang Tong-Chuan He Yulong Zou | 2020 | Genes & Diseases2020，7，2： | 9 |
| 17 | Effects of targeting magnetic drug nanoparticles on human cholangiocarcinoma xenografts in nude mice显示文摘BACKGROUND:Targeting is a new therapeutic tool for malignant tumor as a result of combining nanotechnology with chemotherapeutics.The aim of our study was to investigate the effects of magnetic nanoparticles enveloping a chemotherapeutic drug on human cholangiocarcinoma xenografts in nude mice. METHODS:The human cholangiocarcinoma xenograft model was established in nude mice with the QBC939 cell line.The nude mice were randomly assigned to 7 groups. 0.9%saline or magnetic nanoparticles,including high (group 2),medium(group 4)and low(group 5)dosages, were given to nude mice through the tail vein 20 days after the QBC939 cell line was implanted.Calculations were made 35 days after treatment in order to compare the volumes,inhibition ratios and growth curves of the tumors in each group.Mice in each group were sacrificed randomly to collect tumor tissues and other organs for electron microscopy and pathological examination. RESULTS:The high and medium dosage groups were significantly different from the control group(P<0.05). The tumor inhibition ratios for the high,medium and low dosage groups were 39.6%,14.6%and 7.9%,respectively. The tumor growth curve of groups 5,4,and 2 changed slowly in turn.The high and medium groups showed cell apoptosis under an electron microscope.CONCLUSION:Magnetic nanoparticles can inhibit the growth of human cholangiocarcinoma xenografts in nude mice. | Tang, Tao Zheng, Jian-Wei Chen, Bo Li, Hong Li, Xi Xue, Ke-Ying Ai, Xing Zou, Sheng-Quan | 2007 | Hepatobiliary & Pancreatic Diseases International2007，6，3： | 8 |
| 18 | Improving the Thermal Conductivity and Mechanical Properties of Twocomponent Room Temperature Vulcanized Silicone Rubber by Filling with Hydrophobically Modified SiO_2-Graphene Nanohybrids显示文摘The SiO_2 nanoparticles were coated on the surface of graphene oxide(GO) by sol-gel method to get the SiO_2-G compound.The SiO_2-G was restored and oleophylically modified to prepare hydrophobic modified SiO_2-G(HM-SiO_2-G) which was subsequently added to silicone rubber matrix to prepare two-component room temperature vulcanized(RTV-2) thermal conductive silicone rubber. The morphology, chemical structure and dispersity of the modified graphene were characterized with SEM, FTIR, Raman, and XPS methods.In addition, the heat-resistance behavior, mechanical properties, thermal conductivity, and electrical conductivity of the RTV-2 silicone rubber were also studied systematically. The results showed that the SiO_2 nanoparticles were coated on graphene oxide successfully, and HM-SiO_2-G was uniformly dispersed in RTV-2 silicone rubber. The addition of HM-SiO_2-G could effectively improve the thermal stability, mechanical properties and thermal conductivity of RTV-2 silicone rubber and had no great influence on the electrical insulation performance. | Bo Yang Shuang-Hong Zhang Yi-Feng Zou Wen-Shi Ma Guo-Jia Huang Mao-Dong Li | 2019 | Chinese Journal of Polymer Science2019，37，2： | 8 |
