| 5 | High-entropy ceramics:Present status,challenges,and a look forward显示文摘High-entropy ceramics (HECs) are solid solutions of inorganic compounds with one or more Wyckoff sites shared by equal or near-equal atomic ratios of multi-principal elements.Although in the infant stage,the emerging of this new family of materials has brought new opportunities for material design and property tailoring.Distinct from metals,the diversity in crystal structure and electronic structure of ceramics provides huge space for properties tuning through band structure engineering and phonon engineering.Aside from strengthening,hardening,and low thermal conductivity that have already been found in high-entropy alloys,new properties like colossal dielectric constant,super ionic conductivity,severe anisotropic thermal expansion coefficient,strong electromagnetic wave absorption,etc.,have been discovered in HECs.As a response to the rapid development in this nascent field,this article gives a comprehensive review on the structure features,theoretical methods for stability and property prediction,processing routes,novel properties,and prospective applications of HECs.The challenges on processing,characterization,and property predictions are also emphasized.Finally,future directions for new material exploration,novel processing,fundamental understanding,in-depth characterization,and database assessments are given. | Huimin XIANG Yan XING Fu-zhi DAI Hongjie WANG Lei SU Lei MIAO Guojun ZHANG Yiguang WANG Xiwei QI Lei YAO Hailong WANG Biao ZHAO Jianqiang LI Yanchun ZHOU | 2021 | Journal of Advanced Ceramics2021，10，3： | 28 |

| 9 | Role of Ni(NO_3)_2 in the preparation of a magnetic coal-based activated carbon显示文摘The role of Ni(NO3)2 in the preparation of a magnetic activated carbon is reported in this paper.Magnetic coal-based activated carbons(MCAC) were prepared from Taixi anthracite with low ash content in the presence of Ni(NO3)2.The MCAC materials were characterized by a vibrating sample magnetometer(VSM),X-ray diffraction(XRD),a scanning electric microscope(SEM),and by N2 adsorption.The cylindrical precursors and derived char were also subjected to thermogravimetric analysis to compare their behavior of weight losses during carbonization.The results show that MCAC has a larger surface area(1074 m2/g) and a higher pore volume(0.5792 cm3/g) with enhanced mesopore ratio(by about 10%).It also has a high saturation magnetization(1.6749 emu/g) and low coercivity(43.26 Oe),which allows the material to be magnetically separated.The MCAC is easily magnetized because the nickel salt is converted into Ni during carbonization and activation.Metallic Ni has a strong magnetism on account of electrostatic interaction.Added Ni(NO3)2 catalyzes the carbonization and activation process by accelerating burn off of the carbon,which contributes to the development of mesopores and macropores in the activated carbon. | ZhangJun Xie Qiang Liu Juan Yang Mingshun Yao Xing | 2011 | Mining Science and Technology2011，21，4： | 17 |

| 11 | Facile metagrating holograms with broadband and extreme angle tolerance显示文摘The emerging meta-holograms rely on arrays of intractable meta-atoms with various geometries and sizes for customized phase profiles that can precisely modulate the phase of a wavefront at an optimal incident angle for given wavelengths.The stringent and band-limited angle tolerance remains a fundamental obstacle for their practical application,in addition to high fabrication precision demands.Utilizing a different design principle,we determined that facile metagrating holograms based on extraordinary optical diffraction can allow the molding of arbitrary wavefronts with extreme angle tolerances(near-grazing incidence)in the visible–near-infrared regime.By modulating the displacements between uniformly sized meta-atoms rather than the geometrical parameters,the metagratings produce a robust detour phase profile that is irrespective of the wavelength or incident angle.The demonstration of high-fidelity meta-holograms and in-site polarization multiplexing significantly simplifies the metasurface design and lowers the fabrication demand,thereby opening new routes for flat optics with high performances and improved practicality. | Zi-Lan Deng Junhong Deng Xin Zhuang Shuai Wang Tan Shi Guo Ping Wang Yao Wang Jian Xu Yaoyu Cao Xiaolei Wang Xing Cheng Guixin Li Xiangping Li | 2018 | Light(Science & Applications)2018，7，1： | 17 |
| 12 | D2 dissection in laparoscopic and open gastrectomy for gastric cancer显示文摘AIM: To evaluate the radicalness and safety of laparoscopic D2 dissection for gastric cancer. METHODS: Clinicopathological data from 209 patients with gastric cancer, who underwent radical gastrectomy with D2 dissection between January 2007 and February 2011, were analyzed retrospectively. Among these patients, 131 patients underwent laparoscopyassisted gastrectomy (LAG) and 78 underwent open gastrectomy (OG). The parameters analyzed included operative time, blood loss, blood transfusion, morbidity, mortality, the number of harvested lymph nodes (HLNs), and pathological stage.RESULTS: There were no significant differences in sex, age, types of radical resection [radical proximal gastrectomy (PG + D2), radical distal gastrectomy (DG + D2) and radical total gastrectomy (TG + D2)], and stages between the LAG and OG groups (P > 0.05). Among the two groups, 127 cases (96.9%) and 76 cases (97.4%) had 15 or more HLNs, respectively. The average number of HLNs was 26.1 ± 11.4 in the LAG group and 24.2 ± 9.3 in the OG group (P = 0.233). In the same type of radical resection, there were no signifi cant differences in the number of HLNs between the two groups (PG + D2: 21.7 ± 7.5 vs 22.4 ± 9.3; DG + D2: 25.7 ± 11.0 vs 22.3 ± 7.9; TG + D2: 30.9 ± 13.4 vs 29.3 ± 10.4; P > 0.05 for all comparisons). Tumor free margins were obtained in all cases. Compared with OG group, the LAG group had signifi cantly less blood loss, but a longer operation time (P < 0.001). The morbidity of the LAG group was 9.9%, which was not signifi cantly different from the OG group (7.7%) (P = 0.587). The mortality was zero in both groups. CONCLUSION: Laparoscopic D2 dissection is equivalent to OG in the number of HLNs, regardless of tumor location. Thus, this procedure can achieve the same radicalness as OG. | Ming Cui lia-Di Xing Yi-Yuan Ma Zhen-Dan Yao Nan Zhang Xiang-Qian Su Wei Yang | 2012 | World Journal of Gastroenterology2012，18，8： | 16 |
| 13 | Overexpression of insulin-like growth factor-Ⅰ receptor as a pertinent biomarker for hepatocytes malignant transformation显示文摘AIM:To investigate the dynamic features of insulinlike growth factor-Ⅰreceptor(IGF-ⅠR)expression in rat hepatocarcinogenesis,and the relationship between IGF-ⅠR and hepatocytes malignant transformation at mRNA or protein level.METHODS:Hepatoma models were made by inducing with 2-fluorenylacetamide(2-FAA)on male SpragueDawley rats.Morphological changes of hepatocytes were observed by pathological Hematoxylin and eosin staining,the dynamic expressions of liver and serum IGF-ⅠR were quantitatively analyzed by an enzymelinked immunosorbent assay.The distribution of hepatic IGF-ⅠR was located by immunohistochemistry.The fragments of IGF-ⅠR gene were amplified by reverse transcription-polymerase chain reaction,and confirmed by sequencing.RESULTS:Rat hepatocytes after induced by 2-FAA were changed dynamically from granule-like degeneration,precancerous to hepatoma formation with the progressing increasing of hepatic mRNA or IGF-ⅠR expression.The incidences of liver IGF-ⅠR,IGF-ⅠR mRNA,specific IGF-ⅠR concentration(ng/mg wet liver),and serum IGF-ⅠR level(ng/mL)were 0.0%,0.0%,0.63±0.17,and 1.33±0.47 in the control;50.0%,61.1%,0.65±0.2,and 1.51±0.46 in the degeneration;88.9%,100%,0.66±0.14,and 1.92±0.29 in the precancerosis;and 100%,100%,0.96±0.09,and2.43±0.57 in the cancerous group,respectively.IGF-ⅠR expression in the cancerous group was significantly higher(P<0.01)than that in any of other groups at mRNA or protein level.The closely positive IGF-ⅠR relationship was found between livers and sera(r=0.91,t=14.222,P<0.01),respectively.CONCLUSION:IGF-ⅠR expression may participate in rat hepatocarcinogenesis and its abnormality should be an early marker for hepatocytes malignant transformation. | Xiao-Di Yan Min Yao Li Wang Hai-Jian Zhang Mei-Juan Yan Xing Gu Yun Shi Jie Chen Zhi-Zhen Dong Deng-Fu Yao | 2013 | World Journal of Gastroenterology2013，19，36： | 16 |

| 15 | Electronic Skin from High-Throughput Fabrication of Intrinsically Stretchable Lead Zirconate Titanate Elastomer显示文摘Electronic skin made of thin,soft,stretchable devices that can mimic the human skin and reconstruct the tactile sensation and perception offers great opportunities for prosthesis sensing,robotics controlling,and human-machine interfaces.Advanced materials and mechanics engineering of thin film devices has proven to be an efficient route to enable and enhance flexibility and stretchability of various electronic skins;however,the density of devices is still low owing to the limitation in existing fabrication techniques.Here,we report a high-throughput one-step process to fabricate large tactile sensing arrays with a sensor density of 25 sensors/cm^(2) for electronic skin,where the sensors are based on intrinsically stretchable piezoelectric lead zirconate titanate(PZT)elastomer.The PZT elastomer sensor arrays with great uniformity and passive-driven manner enable highresolution tactile sensing,simplify the data acquisition process,and lower the manufacturing cost.The high-throughput fabrication process provides a general platform for integrating intrinsically stretchable materials into large area,high device density soft electronics for the next-generation electronic skin. | Yiming Liu Huanxi Zheng Ling Zhao Shiyuan Liu Kuanming Yao Dengfeng Li Chunki Yiu Shenghan Gao Raudel Avila Pakpong Chirarattananon Lingqian Chang Zuankai Wang Xian Huang Zhaoqian Xie Zhengbao Yang Xinge Yu | 2020 | Research2020，，1： | 11 |
| 16 | Identification and Practical Application of Silicate-dissolving Bacteria显示文摘Slime-forming bacteria were isolated from soils, rock surface and earthworm intestine, and their effects on dissolving silicate minerals and tomato growth were examined. One of the bacteria, Bacillus mucilaginosus RGBc13, had particularly strong ability to form slime and dissolve silicates. RGBc13 could also colonize and develop in both non-rhizosphere and rhizosphere soil. Total number of slime-forming bacteria increased from 2.9 × 103 cfu·g- 1and 8.4 × 103 cfu·g-1 to 9.6 × 106 cfu·g-1 and 6.0 × 107 cfu·g-1 in the non-rhizosphere and rhizosphere soils respectively. Potassium and phosphorus nutritional conditions in the rhizosphere were markedly improved through inoculation of this bacterium. Available K and P respectively increased from 25.86 and 3.63mg· kg-1 in the non-rhizosphere soil to 91.23 and 5.74mg· kg-1 in the rhizosphere soil. Tomato biomass increased by 125%, K and P uptakes were more than 150%, greater than the non- inoculation. Thus, there is a potential in applying RGBc13 for improving plant K and P nutrition. | LIN Qi-mei, RAO Zheng-hua, SUN Yan-xing, YAO Jun and XING Li-jun( Department of Soil and Water Sciences , China Agricultural University, Beijing 100094 Institute of Plant Nutrition and Resources , Beijing Academy of Agricultural and Forestry Sciences, Beijing 100081 ) | 2002 | Agricultural Sciences in China2002，1，1： | 11 |
| 17 | Annexin A2 silencing inhibits invasion, migration, and tumorigenic potential of hepatoma cells显示文摘AIM: To investigate the effects of Annexin A2 (ANXA2) silencing on invasion, migration, and tumorigenic potential of hepatoma cells. METHODS: Human hepatoma cell lines [HepG2, SMMC-7721, SMMC-7402, and MHCC97-H, a novel human hepatocellular carcinoma (HCC) cell line with high metastasis potential] and a normal hepatocyte cell line(LO2) were used in this study. The protein and mRNA expression levels of ANXA2 were analysed by western blotting and real-time polymerase chain reaction, re-spectively. The intracellular distribution profile of ANXA2 expression was determined by immunofluorescence and immunohistochemistry. Short hairpin RNA target-ing ANXA2 was designed and stably transfected into MHCC97-H cells. Cells were cultured for in vitro analy-ses or subcutaneously injected as xenografts in mice for in vivo analyses. Effects of ANXA2 silencing on cell growth were assessed by cell counting kit-8 (CCK-8) as-say (in vitro ) and tumour-growth assay (in vivo ), on cell cycling was assessed by flow cytometry and propidium iodide staining (in vitro ), and on invasion and migration potential were assessed by transwell assay and wound-healing assay, respectively (both in vitro ). RESULTS: The MHCC97-H cells, which are known to have high metastasis potential, showed the highest lev-el of ANXA2 expression among the four HCC cell types examined; compared to the LO2 cells, the MHCC97-H expression level was 8-times higher. The ANXA2 expres-sion was effectively inhibited (about 80%) by ANXA2-specific small hairpin RNA (shRNA). ANXA2 expression in the MHCC97-H cells was mainly localized to the cel-lular membrane and cytoplasm, and some localization was detected in the nucleus. Moreover, the proliferation of MHCC97-H cells was obviously suppressed by shR-NA-mediated ANXA2 silencing in vitro , and the tumour growth inhibition rate was 38.24% in vivo . The per-centage of MHCC97-H cells in S phase dramatically de-creased (to 27.76%) under ANXA2-silenced conditions. Furthermore, ANXA2-silenced MHCC97-H cells showed lower invasiveness (percentage of invading cells de-creased to 52.16%) and suppressed migratory capacity (migration distance decreased to 63.49%). It is also worth noting that shRNA-mediated silencing of ANXA2 in the MHCC97-H cells led to abnormal apoptosis. CONCLUSION: shRNA-mediated silencing of ANXA2suppresses the invasion, migration, and tumorigenic potential of hepatoma cells, and may represent a useful target of future molecular therapies. | Hai-Jian Zhang Deng-Fu Yao Min Yao Hua Huang Li Wang Mei-Juan Yan Xiao-Di Yan Xing Gu Wei Wu Shao-Lin Lu | 2013 | World Journal of Gastroenterology2013，19，24： | 11 |

| 19 | Fluid-structure Interaction Analysis and Lifetime Estimation of a Natural Gas Pipeline Centrifugal Compressor under Near-choke and Near-surge Conditions显示文摘Up to present, there have been no studies concerning the application of fluid-structure interaction(FSI) analysis to the lifetime estimation of multi-stage centrifugal compressors under dangerous unsteady aerodynamic excitations. In this paper, computational fluid dynamics(CFD) simulations of a three-stage natural gas pipeline centrifugal compressor are performed under near-choke and near-surge conditions, and the unsteady aerodynamic pressure acting on impeller blades are obtained. Then computational structural dynamics(CSD) analysis is conducted through a one-way coupling FSI model to predict alternating stresses in impeller blades. Finally, the compressor lifetime is estimated using the nominal stress approach. The FSI results show that the impellers of latter stages suffer larger fluctuation stresses but smaller mean stresses than those at preceding stages under near-choke and near-surge conditions. The most dangerous position in the compressor is found to be located near the leading edge of the last-stage impeller blade. Compressor lifetime estimation shows that the investigated compressor can run up to 102.7 h under the near-choke condition and 200.2 h under the near-surge condition. This study is expected to provide a scientific guidance for the operation safety of natural gas pipeline centrifugal compressors. | JU Yaping LIU Hui YAO Ziyun XING Peng ZHANG Chuhua | 2015 | Chinese Journal of Mechanical Engineering2015，28，6： | 11 |
| 20 | Enhanced therapeutic effects of combined chemotherapeutic drugs and midkine antisense oligonucleotides for hepatocellular carcinoma显示文摘AIM: To evaluate the effect of combined antisense oligonucleotides targeting midkine (MK-AS) and chemotherapeutic drugs [cisplatin(DDP), 5-fluorouracil (5-FU) and adriamycin (ADM)] on inhibition of HepG2 cell proliferation, and to analyze the efficacy of MK-AS used in combined ADM in in situ human hepatocellular carcinoma (HCC) model. METHODS: HepG2 cells were treated with MK-AS and/or chemotherapeutic drugs mediated by Lipofectin, and cell growth activity was determined by MTS assay. An in situ HCC model was used in this experiment. MK- AS, ADM and MK-AS + ADM were given intravenously for 20 d, respectively. The animal body weight and their tumor weight were measured to assess the effect of the combined therapy in vivo. RESULTS: Combined treatment with MK-AS reduced the IC50 of DDP, 5-FU and ADM in HepG2 cells. MK-AS significantly increased the inhibition rate of DDP, 5-FU and ADM. Additionally, synergism (Q 1.15) occurred at a lower concentration of ADM, 5-FU and DDP with combined MK-AS. Combined treatment with MK-AS and ADM resulted in the more growth inhibition on in situ human HCC model compared with treatment with chemotherapeutic drugs alone. CONCLUSION: MK-AS increases the chemosensitivity in HepG2 cells and in situ human HCC model, and thecombination of MK-AS and ADM has a much better in vitro and in vivo synergism. | Li-Cheng Dai Xiang Wang Xing Yao Yong-Liang Lu Jin-Liang Ping Jian-Fang He | 2007 | World Journal of Gastroenterology2007，13，13： | 10 |
