1Synthesis of Porous NiO Nanocrystals with Controllable Surface Area and Their Application as Supercapacitor Electrodes显示文摘We report a facile way to grow various porous NiO nanostructures including nanoslices,nanoplates,and nanocolumns,which show a structure-dependence in their specific charge capacitances.The formation of controllable porosity is due to the dehydration and re-crystallization of β-Ni(OH)_(2) nanoplates synthesized by a hydrothermal process.Thermogravimetric analysis shows that the decomposition temperature of the β-Ni(OH)_(2) nanostructures is related to their morphology.In electrochemical tests,the porous NiO nanostructures show stable cycling performance with retention of specific capacitance over 1000 cycles.Interestingly,the formation of nanocolumns by the stacking of β-Ni(OH)_(2) nanoslices/plates favors the creation of small pores in the NiO nanocrystals obtained after annealing,and the surface area is over five times larger than that of NiO nanoslices and nanoplates.Consequently,the specific capacitance of the porous NiO nanocolumns(390 F/g)is significantly higher than that of the nanoslices(176 F/g)or nanoplates(285 F/g)at a discharge current of 5 A/g.This approach provides a clear illustration of the process-structure-property relationship in nanocrystal synthesis and potentially offers strategies to enhance the performance of supercapacitor electrodes.Xiaojun Zhang Wenhui Shi Jixin Zhu Weiyun Zhao Jan Ma Subodh Mhaisalkar Tuti Lim Maria Yanhui Yang Hua Zhang Huey Hoon Hng Qingyu Yan 2010Nano Research2010,3,9:24
2Expression of hippocampal corticosteroid receptors,as well as corticotrophin-releasing hormone and vasopressin in the hypothalamic paraventricular nucleus,in fornix transected rats显示文摘BACKGROUND:The hippocampus regulates the hypothalamic-pituitary-adrenal axis through negative feedback.The hypothalamic paraventricular nucleus receives neuronal input from the hippocampus via the fornix. OBJECTIVE:To explore whether the negative feedback effect of the hippocampus on the hypothalamic-pituitary-adrenal axis is contributed to the inhibitory effect of mineralocorticoid receptor (MR) and glucocorticoid receptor(GR) in the hippocampus on the paraventricular nucleus via the fornix. DESIGN,TIME AND SETTING:Randomized,controlled,animal experiment.The study was performed at the Department of Histology and Embryology,China Medical University between September 2006 and September 2008. MATERIALS:Rabbit anti-rat anti-MR and rabbit anti-rat anti-GR antibodies were purchased from Santa Cruz Biotechnology,USA.Rabbit anti-rat anti-corticotrophin releasing hormone(CRH) and rabbit anti-rat anti-arginine vasopressin antibodies were purchased from Wuhan Boster. METHODS:A total of 90 male,Wistar rats were randomly divided into model and sham-surgery groups(n=45).Fornix transection was performed in the model group,while the sham-surgery group underwent surgery,but no fornix transection. MAIN OUTCOME MEASURES:Immunohistochemistry was used to examine MR and GR expression in the hippocampus,as well as CRH and anti-arginine vasopressin in the paraventricular nucleus.Western blot was used to measure alterations in MR,GR,and CRH protein expression following fomix transection. RESULTS:Compared with the sham-surgery group,there were no obvious changes in MR and GR expression in the hippocampus,or CRH and anti-arginine vasopressin expression in the paraventricular nucleus within 4 days of fornix transection.However,after 7-10 days,significantly decreased MR and GR expression in the hippocampus,and increased CRH and anti-arginine vasopressin expression in the paraventricular nucleus were observed(P<0.05-0.01). CONCLUSION:Negative feedback from the hippocampus on the hypothalamic-pituitary-adrenal axis might be mediated through the fornix,and the corticosterone actions mediated by hippocampal corticosteroid receptors indirectly modulated the hypothalamic-pituitary-adrenal axis.Fang Han Hong Liu Yanhui Zhang Yuxiu Shi 2009Neural Regeneration Research2009,4,5:4
3Investigation of the consistency of atmospheric CO_2 retrievals from different space-based sensors: Intercomparison and spatiotemporal analysis显示文摘In recent years,global warming caused by emission of CO2has attracted considerable attention from the public.Although the measurements from AIRS,GOSAT,SCIAMACHY and IASI have been frequently used to derive atmospheric CO2concentration,comprehensive quantification of the differences among these CO2products is still not fully investigated yet.In this paper,a series of strategies have been proposed to allow the CO2products from different instruments to be physically inter-comparable.Based on this,these CO2products are inter-compared in terms of magnitude and their spatiotemporal distributions.The results reveal that the correlations among these CO2products are relatively weak,and some discrepancies are detected in terms of the CO2spatiotemporal characteristics,demonstrating more efforts should be made in the future to improve the retrievals of CO2.Their spatial coverage differences reflected in this study imply the great necessity to generate consistent products with improved spatial and temporal continuities by combining these CO2measurements.WANG TianXing SHI JianCheng JING YingYing XIE YanHui 2013Chinese Science Bulletin2013,58,33:4
4Clinical feature and waveform in infantile nystagmus syndrome in children with FRMD7 gene mutations显示文摘Infant nystagmus sydrome presents as involuntary eye movement disorder and can affect seriously ocular function. We performed a retrospective study of clinical data and FRMD7 genetic test results in 12 cases of infantile nystagmus syndrome to correlate waveform, stereopsis, and visual acuity. The patients(age 6.40±2.67 years) had FRMD7 mutations as follows: missense in eight cases, shear in two cases, frameshift in one case, and non-frameshift in one case. Horizontal jerk waveform was observed in six cases, versus horizontal pendulum in five cases and dual jerk in one case. The uncorrected visual acuity(24 eyes) was 0.21±0.12,compared with a corrected visual acuity(24 eyes) of 0.32±0.14. All patients had simultaneous perception, versus fusion function in 10 cases(83.33%) and stereoscopic vision in seven cases(58.33%) using the synoptophore. Eleven cases(91.67%) detected the stereo fly, compared with five cases(41.67%) for stereoscopic circles and seven cases(58.33%) for stereoscopic animals by Titmus test. Stereoscopic vision using the synoptophore did not correlate with the frequency, amplitude, or intensity of nystagmus or with corrected binocular visual acuity. The infantile nystagmus syndrome with FRMD7 mutations in our cases was caused primarily de novo and missense mutations. Visual acuity and binocular visual function were significant impaired, and the waveform was generally horizontal jerk. Also, an infrared videonystagmogram can record the frequency, amplitude, and intensity of nystagmus accurately.Dayong Bai Wei Shi Zhan Qi Wei Li Aihua Wei Yanhui Cui Cheng Li Li Li 2017Science China(Life Sciences)2017,60,7:3

6Ascorbate peroxidase 1 confers resistance to southern corn leaf blight in maize显示文摘Southern corn leaf blight (SCLB), caused by Bipolarismaydis, is one of the most devastatingdiseases affecting maize production. However,only one SLCB resistance gene, conferring partialresistance, is currently known, underscoring theimportance of isolating new SCLB resistancerelatedgenes. Here, we performed a comparativeproteomic analysis and identified 258 proteinsshowing differential abundance during the maizeresponse to B. maydis. These proteins included anascorbate peroxidase (Zea mays ascorbate peroxidase1 (ZmAPX1)) encoded by a gene locatedwithin the mapping interval of a previously identifiedquantitative trait locus associated with SCLBresistance. ZmAPX1 overexpression resulted inlower H_(2)O_(2) accumulation and enhanced resistanceagainst B. maydis. Jasmonic acid (JA)contents and transcript levels for JA biosynthesisand responsive genes increased in ZmAPX1-overexpressing plants infected with B. maydis,whereas Zmapx1 mutants showed the oppositeeffects. We further determined that low levels of H_(2)O_(2) are accompanied by an accumulation of JAthat enhances SCLB resistance. These resultsdemonstrate that ZmAPX1 positively regulatesSCLB resistance by decreasing H_(2)O_(2) accumulationand activating the JA-mediated defensesignaling pathway. This study identified ZmAPX1as a potentially useful gene for increasing SCLBresistance. Furthermore, the generated datamay be relevant for clarifying the functions ofplant APXs.Jinghua Zhang Xingmeng Jia Guan-Feng Wang Shijun Ma Shunxi Wang Qin Yang Xueyan Chen Yuqian Zhang Yajing Lyu Xiaoxu Wang Jiawei Shi Yangtao Zhao Yanhui Chen Liuji Wu 2022Journal of Integrative Plant Biology2022,64,6:2
7Achieving a sub-10 nm nanopore array in silicon by metal-assisted chemical etching and machine learning显示文摘Solid-state nanopores with controllable pore size and morphology have huge application potential.However,it has been very challenging to process sub-10 nm silicon nanopore arrays with high efficiency and high quality at low cost.In this study,a method combining metal-assisted chemical etching and machine learning is proposed to fabricate sub-10 nm nanopore arrays on silicon wafers with various dopant types and concentrations.Through a SVM algorithm,the relationship between the nanopore structures and the fabrication conditions,including the etching solution,etching time,dopant type,and concentration,was modeled and experimentally verified.Based on this,a processing parameter window for generating regular nanopore arrays on silicon wafers with variable doping types and concentrations was obtained.The proposed machine-learning-assisted etching method will provide a feasible and economical way to process high-quality silicon nanopores,nanostructures,and devices.Yun Chen Yanhui Chen Junyu Long Dachuang Shi Xin Chen Maoxiang Hou Jian Gao Huilong Liu Yunbo He Bi Fan Ching-Ping Wong Ni Zhao 2021International Journal of Extreme Manufacturing2021,3,3:2

9Application 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 2019Asian Journal of Urology2019,6,1:2

12Surface and optical properties of silicon nitride deposited by inductively coupled plasma-chemical vapor deposition显示文摘The surface and optical properties of silicon nitride samples with different compositions were investigated. The samples were deposited on In P by inductively coupled plasma chemical vapor deposition using different NH_3 flow rates. Atomic force microscopy measurements show that the surface roughness is increased for the samples with both low and high NH_3 flow rates. By optimization, when the NH_3 flow rate is 6 sccm, a smooth surface with RMS roughness of 0.74 nm over a 5 × 5 μm^2 area has been achieved. X-ray photoelectron spectroscopy measurements reveal the Si/N ratio of the samples as a function of NH_3 flow rate. It is found that amorphous silicon is dominant in the samples with low NH_3 flow rates, which is also proved in Raman measurements. The bonding energies of the Si and N atoms have been extracted and analyzed. Results show that the bonding states of Si atoms transfer from Si^0 to Si^(+4) as the NH_3 flow rate increases.Yi Zhu Xingyou Chen Yingjie Ma Yonggang Zhang Ben Du Yanhui Shi Yi Gu 2018Journal of Semiconductors2018,39,8:1

17Out-of-plane elastic buckling load and strength design of space truss arch with a rectangular section显示文摘The out-of-plane stability of the two-hinged space truss circular arch with a rectangular section is theoretically and numerically investigated in this paper.Firstly,the flexural stiffness and torsional stiffness of space truss arches are deduced.The calculation formula of out-of-plane elastic buckling loads of the space truss arch is derived based on the classical solution of out-of-plane flexural-torsional buckling loads of the solid web arch.However,since the classical solution cannot be used for the calculation of the arch with a small rise-span ratio,the formula for out-of-plane elastic buckling loads of space truss arches subjected to end bending moments is modified.Numerical research of the out-of-plane stability of space truss arches under different load cases shows that the theoretical formula proposed in this paper has good accuracy.Secondly,the design formulas to predict the out-of-plane elastoplastic stability strength of space truss arches subjected to the end bending moment and radial uniform load are presented through introducing a normalized slenderness ratio.By assuming that all components of space truss circular arches bear only axial force,the design formulas to prevent the local buckling of chord and transverse tubes are deduced.Finally,the bearing capacity design equations of space truss arches are proposed under vertical uniform load.Senping WANG Xiaolong LIU Bo YUAN Minjie SHI Yanhui WEI 2022Frontiers of Structural and Civil Engineering2022,16,9:1
