1Single whispering-gallery mode lasing in polymer bottle microresonators via spatial pump engineering显示文摘Single-mode lasing in whispering-gallery mode(WGM)microresonators is challenging to achieve.In bottle microresonators,the highly non-degenerated WGMs are spatially well-separated along the long-axis direction and provide mode-selection capability.In this work,by engineering the pump intensity to modify the spatial gain profiles of bottle microresonators,we demonstrate a simple and general approach to realizing single-mode WGM lasing in polymer bottle microresonators.The pump intensity is engineered into an interference distribution on the bottle microresonator surface.By tuning the spacing between axial positions of the interference pump patterns,the mode intensity profiles of single-bottle WGMs can be spatially overlapped with the interference stripes,intrinsically enabling single-mode lasing and selection.Attractive advantages of the system,including high sidemode suppression factors 420 dB,large spectral tunability 48 nm,low-lasing threshold and reversible control,are presented.Our demonstrated approach may have a variety of promising applications,ranging from tunable single-mode lasing and sensing to nonlinear optics.Fuxing Gu Fuming Xie Xing Lin Shuangyi Linghu Wei Fang Heping Zeng Limin Tong Songlin Zhuang 2017Light(Science & Applications)2017,6,1:17
2Mechanical properties and thermal stability of carbon fiber cloth reinforced sol-derived mullite composites显示文摘For the wide application as thermal protection materials,it is very necessary for mullite ceramics to improve fracture toughness.In this paper,the laminated and stitched carbon fiber cloth preform reinforced mullite(C/mullite)composites were prepared through the route of sol impregnation and heat treatment using the Al2O3-SiO2 sol with a high solid content as raw materials.The C/mullite composites showed a flexural strength of 228.9 MPa that was comparable to that of dense monolithic mullite although the total porosity reached 13.4%.Especially,a fracture toughness of 11.2 MPa·m1/2that was 4–5 times that of dense monolithic mullite was obtained.Strength deterioration due to the carbothermal reduction between carbon fiber and the residual SiO2 in matrix was found above 1200℃.A pyrolytic C(Py C)coating was deposited on carbon fibers as interfacial coating.The chemical damage to carbon fibers was obviously alleviated by the sacrifice of PyC coating.Accordingly,the C/PyC/mullite composites kept strength unchanged up to 1500℃,and showed much higher strength retention ratio than C/mullite composites after annealing at 1600℃.Wei ZHANG Qingsong MA Kuanhong ZENG Songlin LIANG Weiguo MAO 2019Journal of Advanced Ceramics2019,8,2:2
3Effect of Nano Carbon Black and Graphite Flake on Properties of Low Carbon Al2O3-C Refractories显示文摘Low carbon Al_2O_3-C refractories specimens were prepared with tabular alumina( 3. 0- 1. 0,1. 0- 0. 5,0. 6- 0. 2,≤0. 3,≤0. 045 and ≤0. 02 mm),active alumina micropowder( ≤2 μm) and silicon( ≤0. 045mm) as main raw materials. Nano carbon black( N220) and natural graphite flake( ≤0. 074 mm)were adopted as the carbon sources. The specimens were treated at 800,1 000,1 200 and 1 400 ℃ under coke embedded atmosphere. The effects of additions of nano carbon black and graphite flake on mechanical properties and thermal shock resistance of the specimens were studied. Their mechanical properties were measured by threepoint bending test and thermal shock resistance was determined by water quenching method. The phase composition of the specimens was analyzed with X-ray diffraction and microstructures were observed through FESEM.The results reveal that:(1) the strengths of Al_2O_3-C refractories with these two carbon sources show no big differences when coked at lower than 1 000 ℃; when coked at over 1 200 ℃,the strengths of the specimens with graphite added are much higher than those of the specimens containing carbon black due to much more silicon carbide whiskers formed;( 2) since the nano carbon black has small particle size,they can be filled into interstice of Al_2O_3 particles to form the nano carbon network structure,absorbing and relieving the thermal stressgenerated from expansion and contraction and reducing the thermal expansion coefficient of the specimens,thus their thermal shock resistance is better than that of the specimens containing graphite;( 3) low carbon Al_2O_3-C refractories with good mechanical properties and excellent thermal shock resistance can be prepared with combination of nano carbon black and graphite flake.LIAO Ning LI Yawei SANG Shaobai CHEN Songlin ZENG Luju 2016China's Refractories2016,25,2:2

6Nomogram for predicting the overall survival of patients after D2/R0 resection and chemoradiotherapy for stage Ⅲ gastric cancer or gastroesophageal junction cancer显示文摘Objective:To explore the independent factors associated with the overall survival(OS)after D2/R0 resection and adjuvant chemoradiotherapy(CRT)for stage Ⅲ gastric cancer(GC)and gastroesophageal junction(GEJ)cancer,and establish and validate a nomogram model to predict the OS in this patient population.Methods:A total of 569 stage Ⅲ GC or GEJ cancer patients who underwent D2/R0 resection and adjuvant CRT at our center from January 2013 to May 2018 were retrospectively enrolled in this study.The patients were randomly divided into training and validation cohorts in a 3:1 ratio.In the training cohort,univariate and multivariate analysis were conducted to identify clinical factors associated with OS,and a nomogram model was established on the basis of the independent factors.The concordance index(C-index)and the calibration curve were used to validate the prediction power of the nomogram.Results:Overall,427 and 142 patients were enrolled in the training and validation cohorts,respectively.In the univariate and multivariate analyses,age,Lauren's classification,TNM stage,and administration of adjuvant CRT were independent factors for OS to construct the nomogram.The C-index values were 0.654 and 0.613 in the training and validation cohorts,respectively.The calibration curves were identical to the actual OS.Risk stratification based on the nomogram model showed good risk stratification for OS in both groups.Conclusion:Our study included adjuvant CRT as a predictive factor and established a nomogram model for predicting the OS in patients with stage III GC or GEJ after D2/R0 resection and adjuvant therapy.This nomogram could facilitate more individualized prediction of OS in clinical practice.Jinming Shi Wenzhe Kang Songlin Gao Wenyang Liu Yuan Tang Ning Li Qiang Zeng Huiying Ma Haoyue Li Yantao Tian Jing Jin 2023Radiation Medicine and Protection2023,4,3:0
7Safety and efficacy of Endovascular Management of high-grade blunt renal injury显示文摘Objectives:To provide data on the safety and efficacy of renal arterial embolization(RAE)in patients with highgrade blunt renal injury.Materials and methods:Fifteen patients with high-grade blunt renal injury(AAST grades IV-V)admitted to our hospital from July 2014 to December 2019 were retrospectively reviewed in this study.Their clinical success rate and complications were investigated accordingly.Results:Fifteen patients with high-grade blunt renal injury,13 men and 2 women with an average age of 41.6 years,including 11 hemodynamically unstable patients and 4 stable patients,were treated with RAE.Among these patients,73.3%(11 of 15)had grade IV,and 26.7%(4 of 15)had grade V injuries,while 53.3%(8 of 15)patients had concomitant injuries.One patient received main RAE and 14 patients received selective RAE.The clinical success rate after the first embolization was 93.3%(14 of 15).RAE was repeated and was successfully performed in one patient with sustained hematuria.No significant difference in creatinine levels was found before and after embolization.During the follow-up period of 2–82 months,two patients required tube drainage due to urine leaks,one patient developed renal failure requiring renal replacement therapy,and one patient developed secondary hypertension.Conclusions:RAE can provide a high success rate of hemostasis for both hemodynamically stable and unstable patients with high-grade blunt renal injury,and only minor complications are observed with this procedure.Bin Wang Chongpei Wen Songlin Song Guilian Li Yanggang Yan Shoucai Cheng Junmei Zeng Zhidong Lin Yong Wang 2022Journal of Interventional Medicine2022,5,1:0
