| 1 | The Durability of Alkali-Activated Materials in Comparison with Ordinary Portland Cements and Concretes:A Review显示文摘China is the largest producer and user of ordinary Portland cement(OPC),and the rapid growth of infrastructure development demands more sustainable building materials for concrete structures.Alkali-activated materials(AAMs)are a new type of energy-saving and environmentally friendly building material with a wide range of potential applications.This paper compares the durability of AAMs and 0 PC-based materials un der sulfate attack,acid corrosion,carb on ation,and chloride penetratio n.Different AAMs have shown distinct durability properties due to different compositions being formed when different raw materials are used.According to the calcium(Ca)concentration of the raw materials,this paper interprets the deterioration mechanisms of three categories of AAMs:calcium-free,low-calcium,and calcium-rich.Conflicts found in the most recent research are highlighted,as they raise concerns regarding the consistenee and long-term properties of AAMs.Nevertheless,AAMs show better durability performances than OPC-based materials in general. | Aiguo Wang Yi Zheng Zuhua Zhang Kaiwei Liu Yan Li Liang Shi Daosheng Sun | 2020 | Engineering2020，6，6： | 13 |
| 2 | Simple synthesis of sandwich-like SnSe2/rGO as high initial coulombic efficiency and high stability anode for sodium-ion batteries显示文摘Metal selenides owing to their high theoretical capacity and good conductivity are considered as one of the potential candidates for the anode materials of sodium-ion batteries(SIBs).However,their practical applications are greatly restricted by the poor cycling performances and complicated synthesis methods.In this work,a sandwich-like Sn Se2/reduced graphene oxide(r GO)composite with a small amount of r GO(7.3%)is synthesized by a simple one-pot solvothermal technique.The as-synthesized Sn Se2/r GO shows improved initial coulombic efficiency(ICE)of 73.7%,high capacity of 402.0 m Ah g-1 after 150 cycles at 0.1 A g-1 with a retention of 86.2%and outstanding rate performances.The abundant Sn-O-C bonds of synthesized material not only accelerate the charge transfer at the interface but also enhance the mechanical strength to accommodate volume variation and prevent active material loss during cycling.Moreover,the compact structure leads to thin solid electrolyte interface(SEI)so that high initial coulombic efficiency was obtained.Furthermore,full cells are assembled to test its potential application.This work offers a simple method to synthesize Sn Se2/r GO as a candidate anode for SIBs. | Tingting Wang Kaiwei Yang Juan Shi Shangrui Zhou Liwei Mi Hongping Li Weihua Chen | 2020 | Journal of Energy Chemistry2020，29，7： | 4 |
| 3 | Narrow bandwidth fiber-optic spectral combs for renewable hydrogen detection显示文摘Hydrogen sensors are of great importance to detect leakage in time because the hydrogen-air mixture is highly flammable.Based on optical fiber-based configurations reported so far,using palladium coating only does not meet stringent performance targets,such as fast response time and limited deactivation caused by poisoning.Here,a palladium-gold alloy-coated optical fiber hydrogen sensor,i.e.,highly tilted fiber Bragg grating(TFBG),was proposed by using its narrow bandwidth cladding modes whose effective refractive index(ERI)extends to 1.0 where the gas measurement is possible,which led to faster specific hydrogen measurement response time(a shorter stabilization time during the association and dissociation phases less than 20s and 30s,respectively)and improved deactivation resistance(higher than 99%per test cycle).Meanwhile,the temperature cross-sensitivity can be eliminated via referencing the'target'spectral combs to the core mode.We are sure that this promising configuration extends research directions for rapid,repeatable and high deactivation-resistance in hydrogen gas detection. | Shunshuo CAI Fu LIU Runlin WANG Yongguang XIAO Kaiwei LI Christophe CAUCHETEUR Tuan GUO | 2020 | Science China(Information Sciences)2020，63，12： | 4 |
| 4 | Exploring on the optimal preparation conditions of activated carbon produced from solid waste produced from sugar industry and Chinese medicine factory显示文摘The waste biomass produced from sugar industry and Chinese medicine factory such as bagasse,reed root residue,pueraria residue and liquorice residue were selected as the raw material for the preparation of activated carbon with zinc chloride as activator.With the same activation time,the influence of temperature and impregnation ratio on the preparation of activated carbon was investigated and the reasonable preparation conditions of activated carbon were monitored and analyzed.The obtained activated carbon samples were characterized by scanning electron microscopy,Brunauer-Emmett-Teller,methylene blue adsorption,thermogravimetric analysis and nitrogen adsorption-desorption.Analysis from the experimental data,bagasse,reed root residue,pueraria residue are suitable for preparing activated carbon.For bagasse,the optimum preparation condition was 700℃ and the impregnation ratio was 1:1,the adsorption capacity of methylene blue reached 246.83 mg/g at the moment.For reed root residue,the optimum preparation condition was 600℃ and the impregnation ratio was 1:2,the adsorption capacity of methylene blue reached 268.07 mg/g at the moment.For Pueraria residue,the optimum preparation condition was 700℃ and the impregnation ratio was 1:2.The adsorption capacity of methylene blue reached 297.33 mg/g at the moment. | Zhen Li Qiang Han ZhiFan Zong Qi Xu KaiWei Wang | 2020 | Waste Disposal and Sustainable Energy2020，2，1： | 3 |
| 5 | Electrochemical characterization and microstructure of cold sprayed AA5083/Al_(2)O_(3) composite coatings显示文摘This work focused on the role of Al_(2)O_(3) particles in the corrosion behavior of cold sprayed AA5083 aluminum alloy matrix composite(Al-MMC)coatings.The electrochemical characterization of the coatings was investigated in a 3.5 wt.%NaCl solution as a function of time.The results show that fragmentation of Al_(2)O_(3) particles is not clearly observed in the case of AA5083/20 vol.%Al_(2)O_(3) coating,while the broken Al_(2)O_(3) particles can be seen clearly in AA5083/40 vol.%Al_(2)O_(3) and AA5083/60 vol.%Al_(2)O_(3) coatings.The addition of 20 vol.%Al_(2)O_(3) particles yield the coating with the lowest porosity,and different volume fractions of Al_(2)O_(3)in the feedstock have important effects on the electrochemical behavior of composite coatings.The Al-MMC coating reinforced with 20 vol.%Al_(2)O_(3) particles exhibits the highest Ecorrand the lowest icorrcompared with the other conditions.The order of current density is as follows:AA5083/20vol.%Al_(2)O_(3) | Xiawei Yang Wenya Li Siqi Yu Yaxin Xu Kaiwei Hu Yaobang Zhao | 2020 | Journal of Materials Science & Technology2020，59，24： | 3 |

| 7 | Ultrasensitive detection of endocrine disruptors via superfine plasmonic spectral combs显示文摘The apparent increase in hormone-induced cancers and disorders of the reproductive tract has led to a growing demand for new technologies capable of detecting endocrine disruptors.However,a long-lasting challenge unaddressed is how to achieve ultrahigh sensitive,continuous,and in situ measurement with a portable device for infield and remote environmental monitoring.Here we demonstrate a simple-to-implement plasmonic optical fiber biosensing platform to achieve an improved light–matter interaction and advanced surface chemistry for ultrasensitive detection of endocrine disruptors.Our platform is based on a gold-coated highly tilted fiber Bragg grating that excites high-density narrow cladding mode spectral combs that overlap with the broad absorption of the surface plasmon for high accuracy interrogation,hence enabling the ultrasensitive monitoring of refractive index changes at the fiber surface.Through the use of estrogen receptors as the model,we design an estradiol–streptavidin conjugate with the assistance of molecular dynamics,converting the specific recognition of environmental estrogens(EEs)by estrogen receptor into surface-based affinity bioassay for protein.The ultrasensitive platform with conjugate-induced amplification biosensing approach enables the subsequent detection for EEs down to 1.5×10−3 ng ml−1 estradiol equivalent concentration level,which is one order lower than the defined maximal E2 level in drinking water set by the Japanese government.The capability to detect EEs down to nanogram per liter level is the lowest limit of detection for any estrogen receptor-based detection reported thus far.Its compact size,flexible shape,and remote operation capability open the way for detecting other endocrine disruptors with ultrahigh sensitivity and in various hard-toreach spaces,thereby having the potential to revolutionize environment and health monitoring. | Lanhua Liu Xuejun Zhang Qian Zhu Kaiwei Li Yun Lu Xiaohong Zhou Tuan Guo | 2021 | Light(Science & Applications)2021，10，10： | 2 |
| 8 | Population amount risk assessment of extreme precipitation-induced landslides based on integrated machine learning model and scenario simulation显示文摘In this study,the future landslide population amount risk(LPAR)is assessed based on integrated machine learning models(MLMs)and scenario simulation techniques in Shuicheng County,China.Firstly,multiple MLMs were selected and hyperparameters were optimized,and the generated 11 models were crossintegrated to select the best model to calculate landslide susceptibility;by calculating precipitation for different extreme precipitation recurrence periods and combining the susceptibility results to assess the landslide hazard.Using the town as the basic unit,the exposure and vulnerability of the future landslide population under different Shared Socioeconomic Pathways(SSPs)scenarios in each town were assessed,and then combined with the hazard to estimate the LPAR in 2050.The results showed that the integrated model with the optimized random forest model as the combination strategy had the best comprehensive performance in susceptibility assessment.The distribution of hazard classes is similar to susceptibility,and with an increase in precipitation,the low-hazard area and high-hazard decrease and shift to medium-hazard and very high-hazard classes.The high-risk areas for future landslide populations in Shuicheng County are mainly concentrated in the three southwestern towns with high vulnerability,whereas the northern towns of Baohua and Qinglin are at the lowest risk class.The LPAR increased with the intensity of extreme precipitation.The LPAR differs significantly among the SSPs scenarios,with the lowest in the“fossil-fueled development(SSP5)”scenario and the highest in the“regional rivalry(SSP3)”scenario.In summary,the landslide susceptibility model based on integrated machine learning proposed in this study has a high predictive capability.The results of future LPAR assessment can provide theoretical guidance for relevant departments to cope with future socioeconomic development challenges and make corresponding disaster prevention and mitigation plans to prevent landslide risks from a developmental perspective. | Guangzhi Rong Kaiwei Li Zhijun Tong Xingpeng Liu Jiquan Zhang Yichen Zhang Tiantao Li | 2023 | Geoscience Frontiers2023，14，3： | 2 |
| 9 | Application of fluorescence in situ hybridization in the detection of bladder transitional-cell carcinoma: A multi-center clinical study based on Chinese population显示文摘Objective:To evaluate the diagnostic value of fluorescence in situ hybridization(FISH)in bladder cancer.Methods:We enrolled healthy volunteers and patients who were clinically suspected to have bladder cancer and conducted FISH tests and cytology examinations from August 2007 to December 2008.Receiver operating characteristic(ROC)curve analysis was performed and the area under curve(AUC)values were calculated for both the FISH and urine cytology tests.Results:A cohort of 988 healthy volunteers was enrolled to establish a reference range for the normal population.A total of 4807 patients with hematuria were prospectively,randomly enrolled for the simultaneous analysis of urine cytology,FISH testing,and a final diagnosis as determined by the pathologic findings of a biopsy or a surgically-excised specimen.Overall,the sensitivity of FISH in detecting transitional-cell carcinoma was 82.7%,while that of cytology was 33.4%(p<0.001).The sensitivity values of FISH for non-muscle invasive and muscle invasive bladder transitional-cell carcinoma were 81.7%and 89.6%,respectively(p=0.004).The sensitivity values of FISH for low and high grade bladder cancer were 82.6%and 90.1%,respectively(p=0.002).Conclusion:FISH is significantly more sensitive than voided urine cytology for detecting bladder cancer in patients evaluated for gross hematuria at all cancer grades and stages.Higher sensitivity using FISH was obtained in high grade and muscle invasive tumors. | Liqun Zhou Kaiwei Yang Xuesong Li Yi Ding Dawei Mu Hanzhong Li Yong Yan Jinyi Li Dongwen Wang Wei Li Yulong Cong Jiangping Gao Kewei Ma Yajun Xiao Sheng Zhang Hongyi Jiang Weilie Hu Qiang Wei Xunbo Jin Zhichen Guan Qingyong Liu Danfeng Xu Xin Gao Yongguang Jiang Weimin Gan Guang Sun Qing Wang Yanhui Liu Jianquan Hou Liping Xie Xishuang Song Fengshuo Jin Jiafu Feng Ming Cai Zhaozhao Liang Jie Zhang Dingwei Ye Lin Qi Lulin Ma Jianzhong Shou Yuping Dai Jianyong Shao Ye Tian Shizhe Hong Tao Xu Chuize Kong Zefeng Kang Yuexin Liu Xun Qu Benkang Shi Shaobin Zheng Yi Lin Shujie Xia Dong Wei Jianbo Wu Weiling Fu Zhiping Wang Jianbo Liang | 2019 | Asian Journal of Urology2019，6，1： | 2 |

| 14 | HERG1 K^+ Channels on the Leukemic Cells Mediated Angiogenesis in vitro显示文摘Human ether-a-go-go-related gene(HERGl) K^+ channels are overexpressed in leukemia,which contributes to neoangiogenesis.The purpose of this study was to investigate the role of HERGl K^+ channels on leukemia angiogenesis.We cultured human umbilical vein endothelial cells(HUVECs) in conditioned media,which were derived from leukemic cells with or without E-4031,a HERGl K+ channel special inhibitor.The HUVECs proliferation was measured using CCK-8 assay and migration by a Trans-well.Endothelial tube formation was investigated using Matrigel.Vascular endothelial growth factor(VEGF) levels were tested by ELISA and VEGF mRNA expression using RT-PCR.Our results revealed that blocking HERGl K^+ channels could inhibit leukemia-induced HUVECs proliferation,migration,and tube formation in vitro.The results suggested that HERGl K^+ channels could increase leukemia angiogenesis.Furthermore,blockage of HERGl K^+ channels could also decrease leukemic cells secreting VEGF and expressing VEGF mRNA.HERGl K channels have a promoting effect on leukemia angiogenesis,and the possible mechanism may be that HERGl K^+channels enhance VEGF expression.Thus,HERGl K channel is a potential target of antiangiogenesis in leukemia. | LI Huiyu GUO Dongmei ZHENG Fang LIANG Kaiwei LI Wenying JIE Shenghua | 2014 | Wuhan University Journal of Natural Sciences2014，19，2： | 1 |

| 16 | Single site catalyst with enzyme-mimic micro-environment for electroreduction of CO_(2)显示文摘Single site catalysts provide a unique platform for mimicking natural enzyme due to their tunable interaction between metal center and coordinated ligand.However,most works have focused on preparing structural and functional models of nature enzyme,with less reports also taking the local chemical environment,i.e.,functional/catalytic residues around the active site which is an essential feature of enzymes,into consideration.Herein,we report a Co-centered porphyrinic polymer containing the enzyme-mimic micro-environment,where the linker triazole over CoN4 site enables formation of hydrogen bond with the*COOH intermediate,thus promoting the electrocatalytic reduction of CO_(2).As-prepared catalyst achieves the CO_(2)-to-CO conversion of 5,788 h^(−1) turnover frequency value and near unit(~96%)faradaic efficiency at−0.61 V versus reversible hydrogen electrode.This strategy will bring new dimension of designing highly active single-site catalysts. | Chang Long Kaiwei Wan Xueying Qiu Xiaofei Zhang Jianyu Han Pengfei An Zhongjie Yang Xiang Li Jun Guo Xinghua Shi Hui Wang Zhiyong Tang Shaoqin Liu | 2022 | Nano Research2022，15，3： | 1 |
| 17 | Application of Air-cooled Blast Furnace Slag Aggregates as Replacement of Natural Aggregates in Cement-based Materials:A Study on Water Absorption Property显示文摘The influence of air-cooled blast furnace slag aggregates as replacement of natural aggregates on the water absorption of concrete and mortar was studied, and the mechanism was analyzed. The interface between aggregate and matrix in concrete was analyzed by using a micro-hardness tester, a laser confocal microscope and a scanning electron microscope with backscattered electron image mode. The pore structure of mortar matrixes under different curing conditions was investigated by mercury intrusion porosimetry. The results showed that when natural aggregates were replaced with air-cooled blast furnace slag aggregates in mortar or concrete, the content of the capillary pore in the mortar matrix was reduced and the interfacial structure between aggregate and matrix was improved, resulting in the lower water absorption of mortar or concrete. Compared to the concrete made with crushed limestone and natural river sand, the initial absorption coefficient, the secondary absorption coefficient and the water absorption capacity through the surface for 7 d of the concrete made from crushed air-cooled blast furnace slag and air-cooled blast furnace slag sand were reduced by 48.9%, 52.8%, and 46.5%, respectively. | 王爱国 liu peng liu kaiwei li yan zhang gaozhan 孙道胜 | 2018 | Journal of Wuhan University of Technology(Materials Science)2018，33，2： | 1 |

| 19 | In situ plasmonic&electrochemical fiber-optic sensor for multi-metal-ions detection显示文摘High precision and high throughput detection of heavy metal ions is essential for water quality monitoring and assessment.Herein,we propose a plasmonic&electrochemical dual-mode fiber sensing probe for label-free and real-time detection of multiple ions(Pb^(2+)and Cu^(2+)as examples).This sensor comprises a multimode fiber-single mode fiber reflection probe,the outer surface of which is coated with a gold nanofilm to excite the surface plasmon resonance(SPR)optically and simultaneously serves as an electrochemical working electrode.In traditional electrochemical detection,the enrichment of ions cannot be detected in real-time.However,by utilizing the plasmonic&electrochemical dual-mode detection method,various kinds of metal ions can be deposited onto the gold nanofilm and selectively oxidized during forward potential scanning,and the entire electrochemical process can be monitored by SPR measurement.We experimentally demonstrate that the sensor can simultaneously detect Pb^(2+)and Cu^(2+)in a mixed solution in real-time,providing a linear response over the ion concentration range from 10^(-12)to 10^(-7)M and offering an excellent detection limit(1.69×10^(-14)–5.49×10^(-13)M).The proposed dual-mode fiber sensor has the benefits of remote sensing,compact footprint,and cost-effectiveness and shows excellent potential for water quality risk management in difficult-to-reach environments. | Xiaoling PENG Zhiyong YANG Bo PENG Zhi LI Zhicong REN Xicheng WANG Jiahai LI Zhencheng LI Liang CHEN Daotong YOU Kaiwei LI Jianqing LI Tuan GUO | 2024 | Science China(Information Sciences)2024，67，1： | 0 |
| 20 | Operando monitoring of dendrite formation in lithium metal batteries via ultrasensitive tilted fiber Bragg grating sensors显示文摘Lithium(Li)dendrite growth significantly deteriorates the performance and shortens the operation life of lithium metal batteries.Capturing the intricate dynamics of surface localized and rapid mass transport at the electrolyte–electrode interface of lithium metal is essential for the understanding of the dendrite growth process,and the evaluation of the solutions mitigating the dendrite growth issue.Here we demonstrate an approach based on an ultrasensitive tilted fiber Bragg grating(TFBG)sensor which is inserted close to the electrode surface in a working lithium metal battery,without disturbing its operation.Thanks to the superfine optical resonances of the TFBG,in situ and rapid monitoring of mass transport kinetics and lithium dendrite growth at the nanoscale interface of lithium anodes have been achieved.Reliable correlations between the performance of different natural/artificial solid electrolyte interphases(SEIs)and the time-resolved optical responses have been observed and quantified,enabling us to link the nanoscale ion and SEI behavior with the macroscopic battery performance.This new operando tool will provide additional capabilities for parametrization of the batteries’electrochemistry and help identify the optimal interphases of lithium metal batteries to enhance battery performance and its safety. | Xile Han Hai Zhong Kaiwei Li Xiaobin Xue Wen Wu Nan Hu Xihong Lu Jiaqiang Huang Gaozhi Xiao Yaohua Mai Tuan Guo | 2024 | Light(Science & Applications)2024，13，1： | 0 |
