| 1 | Effects of minor Sc on the microstructure and mechanical properties of Al-Zn-Mg-Cu-Zr based alloys显示文摘Five kinds of Al-Zn-Mg-Cu-Zr based alloys with different Sc additions were prepared by ingot metallurgy. The effects of minor Sc on the microstructure and mechanical properties of Al-Zn-Mg-Cu-Zr based alloys were investigated using tensile tests, optical microscopy (OM), and transmission electron microscopy (TEM). The results show that the ultimate tensile strength and yield strength are improved by 94 and 110 MPa, respectively, and the elongation to failure remains at a reasonable extent (11.1%) in the Al-Zn-Mg-Cu-Zr based alloy with 0.21 wt.% Sc addition after solution heat treatment at 475°C for 40 min and then aged at 120°C for 24 h. The addition of minor Sc induces the formation of Al3(Sc,Zr) particles, which are highly effective in refining the cast microstructures, retarding recrystallization, and pinning dislocations. The increment of strength is attributed mainly to fine grain strengthening, precipitation strengthening of Al3(Sc,Zr) particles, and substructure strengthening. | LI Wenbin PAN Qinglin ZOU Liang LIANG Wenjie HE Yunbin LIU Junsheng | 2009 | Rare Metals2009，28，1： | 12 |

| 3 | Effects of tourmaline on nitrogen removal performance and biofilm structures in the sequencing batch biofilm reactor显示文摘The effects of tourmaline on nitrogen removal performance and biofilm structures were comparatively investigated in two identical laboratory-scale sequencing batch biofilm reactors(SBBRs)(denoted SBBR1 and SBBR2) at different nitrogen loading rates(NLRs) varying from(0.24 ± 0.01) to(1.26 ± 0.02) g N/(L·day). SBBR1 was operated in parallel with SBBR2, but SBBR1 was filled with polyurethane foam loaded tourmaline(TPU) carriers and another(SBBR2) filled with polyurethane foam(PU) carriers. Results obtained from this study showed that the excellent and stable performance of SBBR1 was obtained. Ammonia nitrogen removal and total nitrogen removal were higher in SBBR1 than that in SBBR2 with increase of NLR. At an NLR of(0.24 ± 0.01) g N/(L·day), the majority of the spherical and elliptical bacteria were surrounded by the extracellular polymeric substance(EPS) and bacillus or filamentous bacteria in two SBBRs biofilms. When NLR increased to(1.26 ± 0.02) g N/(L·day), the clusters were more obvious in the SBBR1 biofilm than that in the SBBR2 biofilm. Bacteria in SBBR1 were inclined to synthesis more EPS, and the formed EPS could protect the bacteria from free ammonia(FA) under extreme condition NLR(1.26 ± 0.02) g N/(L·day). The results of polymerase chain reaction-denaturing gradient gel electrophoresis analysis showed that the microbial community similarity in SBBR2 decreased more obviously than that in SBBR1 with the increase of NLR, which the microbial community in SBBR1 was relatively stable. | Chong Tan Haoran Xu Di Cui Jinlong Zuo Junsheng Li Yubin Ji Shan Qiu Lin Yao Ying Chen Yingjie Liu | 2018 | Journal of Environmental Sciences2018，30，5： | 10 |
| 4 | Occurrence and infection risk of waterborne pathogens in Wanzhou watershed of the Three Gorges Reservoir, China显示文摘The Three Gorges Reservoir (TGR), formed by China's Yangtze Three Gorges Project, is the largest lake in the world, but there is too little information available about fecal contamination and waterborne pathogen impacts on this aquatic ecosystem. During two successive 1-year study periods (July 2009 to July 2011), the water quality in Wanzhou watershed of the TGR was tested with regard to the presence of fecal indicators and pathogens. According to Chinese and World Health Organization water quality standards, water quality in the mainstream was good but poor in backwater areas. Salmonella, Enterohemorrhagic Escherichia coli (EHEC), Giardia and Cryptosporidium were detected in the watershed. Prevalence and concentrations of the pathogens in the mainstream were lower than those in backwater areas. The estimated risk of infection with Salmonella, EHEC, Cryptosporidium, and Giardia per exposure event ranged from 2.9 × 10 -7 to 1.68 × 10-5 , 7.04 × 10-10 to 2.36 × 10-7 , 5.39 × 10-6 to 1.25 × 10-4 and 0 to 1.2 × 10-3 , respectively, for occupational divers and recreational swimmers exposed to the waters. The estimated risk of infection at exposure to the 95% upper confidence limit concentrations of Salmonella, Cryptosporidium and Giardia may be up to 2.62 × 10-5 , 2.55 × 10-4 and 2.86 × 10-3 , respectively. This study provides useful information for the residents, health care workers and managers to improve the safety of surface water and reduce the risk of fecal contamination in the TGR. | Guosheng Xiao Zhaodan Wang Ji'an Chen Zhiqun Qiu Yanjie Li Junsheng Qi Wenyi Liu Weiqun Shu | 2013 | Journal of Environmental Sciences2013，25，9： | 7 |
| 5 | Investigation on the fabrication of lightweight aggregate with acid-leaching tailings of vanadium-bearing stone coal minerals and red mud显示文摘Proper treatment of acidleaching tailings(ALTs)of vanadiumbearing stone coal minerals is of great urgency.One approach is adding it into the raw materials during the preparation of lightweight aggregate(LWA).But clay is always needed.In this paper,another solid waste,red mud,was mixed with ALTs as a source of flux components instead of clay.Evaluation of the physical characteristics,morphological structures,as well as crystal phases during the sintering process were investigated.When their mixtures with a proper ratio were sintered at 1080℃,a glassy phase with certain viscosity was formed,and the gases generated simultaneously were encapsulated by the melt.Finally,LWA with a onehour water absorption as low as 1.46%,a bulk density as low as 728.76 kgm 3 and a compressive strength as high as 10.77 MPa was fabricated. | Chunguang Song Hongling Zhang Yuming Dong Lili Pei Honghui Liu Junsheng Jiang Hongbin Xu | 2021 | Chinese Journal of Chemical Engineering2021，34，4： | 6 |
| 6 | A nomogram to predict prognosis for gastric cancer with peritoneal dissemination显示文摘Objective: To identify independent prognostic factors to be included in a nomogram to predict the prognosis of gastric cancer patients with peritoneal dissemination.Methods: This is a retrospective study on 684 patients with a histological diagnosis of gastric cancer with peritoneal dissemination from the Sun Yat-sen University Cancer Center as the development set, and 62 gastric cancer patients from the Sixth Affiliated Hospital of Sun Yat-sen University as the validation group. Chi-square test and Cox regression analysis were used to compare the clinicopathological variables and the prognosis of gastric cancer patients with peritoneal dissemination. The Harrell's concordance index(C-index) and calibration curve were determined for comparisons of predictive ability of the nomogram.Results: Univariate and multivariate analyses showed that serum carcinoembryonic antigen(CEA) level(P=0.032), ascites grading(P=0.008), presence of extraperitoneal metastasis(P<0.001), seeding status(P=0.016) and performance status(P=0.009) were independent prognostic factors for gastric cancer patients with peritoneal dissemination in the development set. The nomogram model was constructed using these five factors. Internal validation showed that the C-index of the model was 0.641. For the external validation, the C-index of this model was 0.709.Conclusions: We developed and validated a nomogram to predict the prognosis for gastric cancer patients with peritoneal dissemination. This nomogram may play an important clinical role in guiding palliative therapy for these types of patients, although it may need more data for optimization. | Shi Chen Xijie Chen Runcong Nie Liying Ou Yang Aihong Liu Yuanfang Li Zhiwei Zhou Yingbo Chen Junsheng Peng | 2018 | Chinese Journal of Cancer Research2018，30，4： | 5 |
| 7 | Therapeutic effect of natural melanin from edible fungus Auricularia auricula on alcohol-induced liver damage in vitro and in vivo显示文摘This study explored the therapeutic effects of Auricularia auricula melanin(AAM)on alcoholic liver damage in vitro and in vivo.Human normal liver L02 cells were pre-treated with ethanol and then treated with AAM to explore the therapeutic effect of AAM on ethanol-induced hepatocyte injury.The results show that AAM signifi cantly elevated the cell viability,ameliorated the cell morphology,reduced the ROS and increased the GSH/GSSG of ethanol-pretreated L02 cells.Then,mice were administered with ethanol to induce acute alcoholic liver damage,and administered with AAM to further study the therapeutic effect of AAM on alcoholic liver damage in mice.As a result,AAM reduced the levels of ALT,AST,TG,and MDA,increased the levels of ADH,SOD,and CAT in liver damage mice.The therapeutic effect of AAM may be related to inhibition of CYP2E1 expression and activation of Nrf2 and its downstream antioxidase.The research enriched the bioactivity of AAM and provided some ideas for the development of melanin-related health foods. | Ruolin Hou Xin Liu Xiaoping Wu Mingfeng Zheng Junsheng Fu | 2021 | Food Science and Human Wellness2021，10，4： | 4 |
| 8 | Research and Application of Non-symmetrical Roll Bending Control of Cold Rolling Mill显示文摘The existing research of the flatness control for strip cold rolling mainly focuses on the calculation of the optimum adjustment of individual flatness actuator in accordance with the flatness deviation,which can be used for general flatness control.However,it does not work for some special rolling processes,such as the elimination of ultra single side edge-waves and the prevention of strip break due to tilting roll control overshooting.For the purpose of solving these problems,the influences of non-symmetrical work roll bending and intermediate roll bending on flatness control were analyzed by studying efficiencies of them.Moreover,impacts of two kinds of non-symmetrical roll bending control on the pressure distribution between rolls were studied theoretically.A non-symmetrical work roll bending model was developed by theoretical analysis in accordance with practical conditions.The model was applied to the revamp of a 1250 6-H reversible universal crown mill (UCM) cold mill.Theoretical study and practical applications show that the coordination utilization of the non-symmetrical work roll bending control and tilting roll control was effective in flatness control when there appeared bad strip single side edge waves,especially when the incoming strip was with a wedge shape.In addition,the risk of strip break due to tilting control overshooting could be reduced.Furthermore,the non-symmetrical roll bending control can reduce the extent of uneven distribution of pressure between rolls caused by intermediate roll shifting in flatness control and slow down roll wear.The non-symmetrical roll bending control technology has important theoretical and practical significance to better flatness control. | WANG Pengfei ZHANG Dianhua LI Xu LIU Jiawei WANG Junsheng | 2012 | Chinese Journal of Mechanical Engineering2012，25，1： | 4 |

| 11 | Improved and excellent CO sensing properties of Cu-doped TiO_2 nanofibers显示文摘Cu-doped TiO2 nanofibers with an average diameter of about 80 nm are synthesized through an electrospinning method. Both anatase and rutile crystallographic structures are found in the fibers based on XRD results. Compared with pure TiO2 nanofibers, the Cu-doped TiO2 nanofibers exhibit improved CO sensing properties at 300°C. The sensitivity of Cu-doped TiO2 nanofibers is up to 3 when the sensor is exposed to 5 ppm CO, and the response and recovery times are about 4 and 8 s, respectively. Good selectivity is also observed in our investigations. These results indicate that the Cu-doped TiO2 nanofibers can be used to fabricate high performance CO sensors in practice. | WANG Biao ZHAO YuDong HU LiMing CAO JunSheng GAO FengLi LIU Yun WANG LiJun | 2010 | Chinese Science Bulletin2010，55，3： | 3 |

| 13 | Analysis of genetic alterations identifies the frequent mutation of GNAS in colorectal laterally spreading tumors显示文摘Dear Editor,Colorectal cancer(CRC)is among the most commonly diagnosed cancer and the leading cause of cancer-related death worldwide[1].Most CRCs develop from adenomas.Laterally spreading tumors(LSTs)are non-polypoid superficial colorectal neoplasms(CRNs)that are larger than 1 cm and typically extend laterally along the luminal wall.Based on surface morphology,it can be classified into a granular or nongranular type.The pathological morphology of LST manifests only as adenoma or with cancer.Recent studies have characterized 45-79%of LSTs as high-grade intraepithelial neoplasia(HGIN)or submucosal invasion;and the risk of submucosal invasion increases with lesion size[2].Hence,LST is considered a precancerous CRC lesion.Patients with LSTs are usually asymptomatic and diagnosis typically occurs during physical examinations or screening colonoscopy. | Lei Pan Junsheng Chen Chaojun Zhu Lu Han Aimin Li Side Liu | 2020 | Cancer Communications2020，40，11： | 3 |
| 14 | Enhancing the mechanical and anticorrosion properties of 316L stainless steel via a cathodic plasma electrolytic nitriding treatment with added PEG显示文摘A cathodic plasma electrolytic nitriding(CPEN)treatment with a urea aqueous solution was performed on 316L stainless steel to rapidly improve its surface properties in this work.Test results show that the PEG2000 macromolecules increased the nitriding energy via enhancing the ability to bond the produced gas film to the metal/electrolyte interface.The cross-sectional morphologies indicate that a thick nitrided layer was obtained when the urea concentration was 543 g I^-1,corresponding to a Vickers hardness 450 HV(0.1),which was 3.5 times larger than that of the substrate.The nitrided layer mainly contained expanded austenite(γN),oxides and iron nitrides(e.g.,Fe3O4 and FeN(0.076)).In terms of its performance,coefficient of friction(COF)of the nitride layer decreased to nearly two-thirds that of the untreated layer,and the passivation current densities of the nitrided sample in a 3.5%NaCl solution decreased by an order of magnitude compared to that of the substrate.Therefore,the approach presented herein provides an attractive way to modify the effect of CPEN in a urea aqueous solution. | Tianyi Zhang Junsheng Wu Lei Jin Zhan Zhang Wan Rong Bowei Zhang Yi Wang Yedong He Wei Liu Xiaogang Li | 2019 | Journal of Materials Science & Technology2019，35，11： | 3 |
| 15 | Novel Flow Field with Superhydrophobic Gas Channels Prepared by One-step Solvent-induced Crystallization for Micro Direct Methanol Fuel Cell显示文摘The CO2-induced capillary blocking in anode flow field is one of the key adverse factors to reduce the performance of a micro-direct methanol fuel cell(l DMFC). In order to solve this problem, new polycarbonate(PC) flow field plates with nested arrangement of hydrophilic fuel channels and superhydrophobic gas channels were designed,fabricated, and tested in this work. The gas channels were treated with solvent-induced crystallization using acetone solution. The superhydrophobicity with 160° water contact angle and 2° tilting angle was obtained on the PC substrates. A dummy cell using hydrogen peroxide decomposition reaction and a test loop were separately set up to evaluate the flow fields' performance. It was found that a 37 % pressure drop decrease can be obtained in the new serpentine flow field compared with that of the conventional one. The benefit of the new flow field to remove gas bubbles was also confirmed by an in situ visualization study on the dummy cell. Results show that the auxiliary superhydrophobic gas channels can speed up the discharge of the gas bubbles from the flow field, which will in turn improve the l DMFC performance. | Junsheng Liang Kuanyao Liu Shouzuo Li Dazhi Wang Tongqun Ren Xiaoying Xu Ying Luo | 2015 | Nano-Micro Letters2015，7，2： | 2 |
