1Catalytic combustion of VOCs on Pt/CuMnCe and Pt/CeY honeycomb monolithic catalysts显示文摘The metal oxides CuMnCe and CeY washcoats on cordierite were prepared using an impregnation method, and then used as support for the active Pt component to prepare the Pt/CuMnCe and Pt/CeY monolithic catalysts for the deep oxidation of VOCs. In comparison with the Pt/CeY, CuMnCe, and CeY monolithic catalysts, the Pt/CuMnCe monolithic catalyst shows an excellent performance for toluene,ethyl acetate,and n-hexane oxidation and the T_(90%) is low to 216, 200 and 260 ℃,respectively. The active components Pt/PtO and CuMnCe result in a better synergetic interaction, which promote the catalyst reducibility, increase the oxygen mobility, and enhance the adsorption and activation of organic molecules.Anming Zhu Ying Zhou Yue Wang Qiulian Zhu Huayan Liu Zekai Zhang Hanfeng Lu 2018Journal of Rare Earths2018,36,12:17

3Is new American Thyroid Association risk classification for hereditary medullary thyroid carcinoma applicable to Chinese patients? A single-center study显示文摘Objective: The American Thyroid Association(ATA) proposed a new risk classification for hereditary medullary thyroid carcinoma(MTC) in 2015. This study aimed to assess whether the new guidelines are suitable for the Chinese population, and reported our experience on prophylactic thyroidectomy.Methods: A total of 73 patients from 22 families were screened as rearranged during transfection(RET) mutation carriers from 2010 to 2016 in Cancer Hospital, Chinese Academy of Medical Science; the medical history for each patient was collected. Based on the initial treatment, we identified the risk factors for poor prognosis by univariate and multivariate logistic regression. Then, 4 RET mutation carriers were enrolled for prophylactic thyroidectomy,and their pathological data and follow-up outcomes were recorded.Results: In univariate and multivariate logistic regression analyses, age at initial surgery and risk classification were significant risk factors for stage Ⅲ/Ⅳ hereditary MTC at initial diagnosis. The likelihood was increased by 11.6% per year of age at initial surgery [95% confidence interval(95% CI), 1.040–1.198; P=0.002). It was 7.888 times more likely to have Ⅲ/Ⅳ stage disease for ATA highest risk patients, compared to ATA moderate risk individuals(95% CI, 1.607–38.717; P=0.003). Postoperative pathological results showed all 4 multiple endocrine neoplasia type 2A(MEN2A) patients had C-cell hyperplasia(CCH); multifocal malignancies were detected in 3 of them. All 4 patients were cured biochemically, and none developed permanent hypoparathyroidism.Conclusions: In Chinese individuals, hereditary MTC aggressiveness is in line with the new ATA risk classification. Germline RET gene mutation carriers should undergo prophylactic thyroidectomy according to basal serum calcitonin levels.Xiwei Zhang Dangui Yan Junyi Wang Hanfeng Wan Yongxia Zhang Yabing Zhang Yuqin He Wensheng Liu Bin Zhang 2017Chinese Journal of Cancer Research2017,29,3:5
4Effect of Ni-V loading on the performance of hollow anatase TiO2 in the catalytic combustion of dichloromethane显示文摘A catalyst based on mixed V-Ni oxides supported on TiO2(Ni-V/TiO2)was obtained using the sol-gel method.Its catalytic performance relative to dichloromethane(DCM)degradation was investigated.Characterization and analysis were conducted using transmission electron microscopy,H2 temperature-programmed reduction,pyridine-Fourier transform infrared spectroscopy(FTIR)characterization,and X-ray diffraction.Results showed that the original hollow anatase structure of pure TiO2 was well-maintained after Ni-V loading.The loading of NiO-VOx not only significantly improved the stability of pure TiO2 but also inhibited the formation of the by-product monochloromethane(MCM).Among the series of Ni-V/TiO2 catalysts,4%Ni-V/TiO2 possessed the highest catalytic activity,with 90%DCM conversion at only 203℃.No by-products and no significant changes in the catalytic activity were observed during combustion of DCM after 100 hr of a continuous stability test.Furthermore,thermogravimetric analysis(O2-TG)and energy dispersive spectrometer(EDS)characterization of the used 4%Ni-V/TiO2 catalyst revealed that no coke deposition or chlorine species could be detected on the catalyst surface.Bing Zhou Xixiong Zhang Yong Wang Jing Xie Kang Xi Ying Zhou Hanfeng Lu 2019Journal of Environmental Sciences2019,31,10:3
5Status and Opportunities of Zinc Ion Hybrid Capacitors: Focus on Carbon Materials, Current Collectors, and Separators显示文摘Zinc ion hybrid capacitors(ZIHCs), which integrate the features of the high power of supercapacitors and the high energy of zinc ion batteries, are promising competitors in future electrochemical energy storage applications. Carbon-based materials are deemed the competitive candidates for cathodes of ZIHC due to their cost-effectiveness, high electronic conductivity, chemical inertness, controllable surface states, and tunable pore architectures. In recent years, great research efforts have been devoted to further improving the energy density and cycling stability of ZIHCs. Reasonable modification and optimization of carbon-based materials offer a remedy for these challenges. In this review, the structural design, and electrochemical properties of carbon-based cathode materials with different dimensions, as well as the selection of compatible, robust current collectors and separators for ZIHCs are discussed. The challenges and prospects of ZIHCs are showcased to guide the innovative development of carbon-based cathode materials and the development of novel ZIHCs.Yanyan Wang Shirong Sun Xiaoliang Wu Hanfeng Liang Wenli Zhang 2023Nano-Micro Letters2023,15,6:2
6One-step synthesis of graphitic-C_3N_4/ZnS composites for enhanced supercapacitor performance显示文摘A series of graphitic-C_3N_4/ZnS(g-C_3N_4/ZnS) supercapacitor electrode materials have been prepared via a one-step calcination process of zinc acetate/thiourea with different mass ratios under nitrogen atmosphere. The optimized g-C_3N_4/ZnS composite shows a highest specific capacitance of 497.7 F/g at 1 A/g and good cycling stability with capacitance retention of 80.4% at 5 A/g after 1000 cycles. Moreover, gC_3N4/ZnS composites display an improved supercapacitor performance in terms of specific capacitance compared to the pure g-C_3N_4 and ZnS. In addition, our designed symmetric supercapacitor device based on g-C_3N_4/ZnS composite electrodes can exhibit an energy density of 10.4 Wh/kg at a power density of 187.3 W/kg. As a result, g-C_3N_4/ZnS composites are expected to be a prospective material for supercapacitors and other energy storage applications.Binbin Wei Hanfeng Liang Rongrong Wang Dongfang Zhang Zhengbing Qi Zhoucheng Wang 2018Journal of Energy Chemistry2018,27,2:2

10Hydrothermal-treated Pt/Al_(2)O_(3) as an excellent catalyst for toluene total oxidation显示文摘The preparation of highly active supported noble metal catalysts with a low noble metal loading has always been the ultimate goal of researchers working on catalysis.Hydrothermally treated Pt/Al_(2)O_(3)(Pt/Al_(2)O_(3)-H)exhibits better catalytic activity than that(Pt/Al_(2)O_(3)-C)treated via the conventional calcination approach.At the high space velocity of100,000 m L/(g·hr),the temperature that correspond to 50%toluene conversion(T50)of Pt/Al_(2)O_(3)-H is 115℃ lower than that of Pt/Al_(2)O_(3)-C,and the turnover frequency(TOF)value can reach 0.0756 sec-1.The mechanism by which the hydrothermal approach enhances Pt/Al_(2)O_(3) activity has been investigated.The structure associated with the high catalytic activity of Pt nanoparticles(NPs)can be retained via hydrothermal treatment.Furthermore,the support is transformed to AlO(OH)with numerous surface hydroxyl groups,which in turn can facilitate the adsorption of toluene.And the synergistic effects of Pt NPs and AlO(OH)increases the contents of Pt in oxidation state and active oxygen,which are beneficial for toluene oxidation.Xiao Chen Yong Wang Jianyu Li Zhongheng Hu Ying Zhou Huayan Liu Hanfeng Lu 2022Journal of Environmental Sciences2022,34,6:1
11Interface engineering of Zn meal anodes using electrochemically inert Al_(2)O_(3)protective nanocoatings显示文摘Aqueous rechargeable Zn-ion batteries are regarded as a promising alternative to lithium-ion batteries owing to their high energy density,low cost,and high safety.However,their commercialization is severely restricted by the Zn dendrite formation and side reactions.Herein,we propose that these issues can be minimized by modifying the interfacial properties through introducing electrochemically inert Al_(2)O_(3)nanocoatings on Zn meal anodes(Al_(2)O_(3)@Zn).The Al_(2)O_(3)nanocoatings can effectively suppress both the dendrite growth and side reactions.As a result,the Al_(2)O_(3)@Zn symmetric cells show excellent electrochemical performance with a long lifespan of more than 4,000 h at 1 mA·cm^(−2)and 1 mAh·cm^(−2).Meanwhile,the assembled Al_(2)O_(3)@Zn//V_(2)O_(5)full cells can deliver a high capacity(236.2 mAh·g^(−1))and long lifespan with a capacity retention of 76.11%after 1,000 cycles at 4 A·g^(−1).Rui Wang Qiongfei Wu Minjie Wu Jiaxian Zheng Jian Cui Qi Kang Zhengbing Qi JiDong Ma Zhoucheng Wang Hanfeng Liang 2022Nano Research2022,15,8:1
12Single-atom electrocatalysis: a new approach to in vivo electrochemical biosensing显示文摘Modulation of interfacial electron transfer has been proven to pave a new approach to in vivo electrochemical monitoring of brain chemistry;however,designing and establishing highly efficient electrocatalytic scheme towards neurochemicals remain a longstanding challenge.Here,we find that recently established single-atom catalyst(SAC)can be used for catalyzing the electrochemical process of physiologically relevant chemicals and thus offers a new avenue to in vivo electrochemical biosensing.To prove this new concept,we used Co single-atom catalyst(Co-SAC),in which the atomic active sites are dispersed in ordered porous N-doping carbon matrix at atomic level,as an example of SACs for analyzing glucose as the physiologically relevant model chemicals.We found that Co-SAC catalyzes the electrochemical oxidation of hydrogen peroxide(H2O2)at a low potential of ca.+0.05 V(vs.Ag/AgCl).This property was further used for developing an oxidase-based glucose biosensor that was used subsequently as a selective detector of an online electrochemical system(OECS)for continuous monitoring of microdialysate glucose in rat brain.The OECS with Co-SAC-based glucose biosensor as the online detector was well responsive to glucose without interference from other electroactive species in brain microdialysate.This study essentially offers a new approach to in vivo electrochemical analysis with SACs as electrocatalysts to modulate interfacial electron transfer.Hanfeng Hou Junjie Mao Yunhu Han Fei Wu Meining Zhang Dingsheng Wang Lanqun Mao Yadong Li 2019Science China Chemistry2019,62,12:1
13RNA-Seq analysis and development of SSR and KASP markers in lentil(Lens culinaris Medikus subsp. culinaris)显示文摘Lentil(Lens culinaris Medikus subsp.culinaris,2 n=14)is a cool-season legume with high production potential for multiple uses.However,limited molecular research has been conducted in this species owing to its large genome,which impedes the generation of genome sequences and the development of molecular markers.In this study,more than 1.37 billion filtered clean reads were collected by RNA-Seq of six diverse lentil accessions and217,836 transcripts and 161,095 unigenes were de novo assembled,yielding respectively 257.1 and 240.6 million nucleotides.The mean transcript length was 1180 bp and the N50 and N90 lengths were respectively 2075 and 479 bp.The mean length of the unigenes was 1494 bp and their N50 and N90 values were respectively 2203 and 714 bp.The unigenes were annotated against seven databases.The FLOWERING LOCUS T(FT)gene homolog in lentil showed high protein sequence similarity to the FT gene homologs of pea and alfalfa.On the basis of the RNA-Seq analysis,26,449 EST-SSR markers were designed in silico,and 276 preliminarily screened markers were selected to evaluate polymorphism in 94 diverse lentil accessions.In total,125(45.29%)of 276 EST-SSR markers were found to be polymorphic.A total of 130,073 SNP loci were detected and 78(61.41%)of 127 SNPs were successfully converted to KASP markers.Population genetic analyses of the lentil accessions with EST-SSR and KASP markers revealed similar genetic structures,suggesting that the RNA-Seq-generated resources and the developed markers are reliable for use in molecular marker-assisted breeding of lentil.Dong Wang Tao Yang Rong Liu Nana Li Xiaomu Wang Ashutosh Sarker Xiaodong Zhang Runfang Li Yanyan Pu Guan Li Yuning Huang Yishan Ji Zhaojun Li Qian Tian Xuxiao Zong Hanfeng Ding 2020The Crop Journal2020,8,6:1

17Recent progress in advanced catalysts for electrocatalytic hydrogenation of organics in aqueous conditions显示文摘Electrocatalytic hydrogenation(ECH)of organics using water as hydrogen donors has been regarded as a green organic reduction technique to replace traditional chemical reactions that use sacrificial chemicals.The development of ECH process provides potential applications in the production of value-added chemicals owing to its low energy consumption,low pollution,high safety,and superior sustainability.However,its application is limited by the low conversion rate and poor selectivity toward desired products.The efficiency of ECH can be improved by rational design of electrocatalysts.This review covers several representative electrocatalytic systems(aldehydes,ketones,phenolic organics,alkynes,and organonitrogen compounds)and summarizes different ECH mechanisms,followed by thorough discussion on the modification strategies of electrocatalysts that are currently adopted to enhance the catalytic performance.Finally,in view of the current challenges for ECH,we discuss possible future directions in the field,aiming to provide guidance to the catalyst design toward highly efficient ECH reactions over different organic feedstocks.Ye Zeng Mengting Zhao Hongliang Zeng Qiu Jiang Fangwang Ming Kai Xi Zhoucheng Wang Hanfeng Liang 2023eScience2023,3,5:0
18Abundant closed-form wave solutions to the simplified modified Camassa-Holm equation显示文摘The simplified modified Camassa-Holm (SMCH) equation is an important nonlinear model equation for identifying various wave phenomena in ocean engineering and science. The new auxiliary equation (NAE) method has been applied to the SMCH equation. Base on the method, we have obtained some novel an- alytical solutions such as hyperbolic, trigonometric, exponential, and rational function solutions of the SMCH equation. For appropriate values of parameters, three dimensional (3D) and two dimensional (2D) graphs are designed by Mathematica. The stability of the model is also discussed in this manuscript. The dynamic and physical behaviors of the solutions derived from the SMCH equation have been ex- tensively discussed by these plots. All our solutions are indispensable for understanding the nonlinear phenomena of dispersive waves that are important in ocean engineering and science. In addition, our results are essential to clarify the various oceanographic applications containing ocean gravity waves, offshore rig in water, energy associated with a moving ocean wave and numerous other related phenom- ena. Finally, the obtained solutions are helpful for studying wave interactions in many new structures and high-dimensional models.S M Rayhanul Islam S M Yiasir Arafat Hanfeng Wang 2023Journal of Ocean Engineering and Science2023,8,3:0
19Effects of Seed Viability and Number of Generations on Genetic Integrity of Soybean Germplasm Zhonghuang 18 by AFLP Markers显示文摘The seeds of a soybean cultivar Zhonghuang 18 were subjected to accelerated aging for 0(population G_0-1), 112(population G_0-2), 154(population G_0-3) and 196 d(population G_0-4), whose germination percentage was found to be 98.0%, 95.0%, 81.0%, and 79.0%, respectively. Then, the four populations were regenerated twice in the field. The first descendant populations were marked as G_1-1, G_1-2, G_1-3 and G_1-4, and the second were marked as G_2-1, G_2-2, G_2-3 and G_2-4, respectively. The genetic variation between the control population(G_0-1) and the experimental populations was analyzed using 12 AFLP primer combinations. The results showed that there was no significant difference in genetic similarity between the 11 experimental populations and the control population G_0-1. The genetic similarity between population G_2-4 and G_0-1 was still as high as 0.933 3, indicating that the F_2 generation of the population whose germination percentage was only 79.0% still had a high genetic similarity to the control population. The results of t-tests revealed that the populations G_1-1, G_2-1, G_1-2 and G_2-2 showed no significant difference from the control population G_0-1 in effective number of alleles per locus(Ae), genetic diversity index(H) and Shannon's diversity index(I), while these indices of populations G_0-3, G_0-4, G_1-3, G_1-4, G_2-3 and G_2-4 were significantly reduced. χ~2 tests indicated that the populations G_1-1 and G_2-1 showed little difference, and the populations G_0-2, G_0-3, G_0-4, G_1-2, G_1-3, G_1-4, G_2-2, G_2-3, and G_2-4 showed great difference in allele frequency distribution from the control population G_0-1, and the difference was greater when the seed viability was lower. Compared with the control population G_0-1, the number of rare alleles(Nr) of the populations G_0-2, G_1-1, G_2-1, G_1-2 and G_2-2 showed no significant difference, while that of the populations G_0-3, G_0-4, G_1-3, G_1-4, G_2-3 and G_2-4 declined obviously. These results revealed that compared with the control population, the genetic diversity and Nr for the descendant populations of the populations with 98.0% and 95.0% germination percentages did not change significantly, but declined greatly for the descendant populations of the populations with 81.0.% and 79.0% percentages. The results suggested that the decline in seed viability has a greater impact than the number of generations on genetic structure of soybean germplasm. So, it is suggested that soybean seed with an initial germination percentage of 98.0% should be regenerated before its germination percentage declines to 81.0%.Dong WANG Xiaodong ZHANG Runfang LI Lingyun LU Xiaomu WANG Xiaohong GU Xia XIN Guangkun YIN Xinxiong LU Hanfeng DING 2019Agricultural Biotechnology2019,8,2:0
20Establishment and Operation of Crop Genebank in Shandong Province显示文摘Shandong Province has abundant and diverse crop germplasm resources, but it is in lack of unified and effective preservation and management, leading to the decline and even extinction of many rare germplasm resources. In this study, the necessity for the establishment of crop genebank in Shandong Province was briefly described. In addition, the type, functions and technical indicators, as well as the operation of the crop genebank were introduced comprehensively to provide a reference for the establishment of genebank by other units or organizations.Dong WANG Runfang LI Shihua LIU Cun'e WANG Lingyun LU Nana LI Hanfeng DING Xiaomu WANG Xiaohong GU Yingjie LIN Xiaodong ZHANG 2017Agricultural Science & Technology2017,18,11:0
