| 2 | Achieving effective broadband microwave absorption with Fe_(3)O_(4)@C supraparticles显示文摘The X band(8 GHz-12 GHz)is the electromagnetic wave band emitted by most electronic instruments in our life,which will cause electromagnetic pollution harm to human health.Due to the coexistence of magnetic loss and dielectric loss,the modified Fe_(3)O_(4)-carbon-based nanomaterial exhibit strong electromagnetic(EM)wave absorptive capacity.However,there is a problem that the effective absorption bandwidth(EAB,the frequency bandwidth of reflection loss is less than-10 dB)of the X band is narrow.Increasing the EAB value of Fe_(3)O_(4)-carbon-based materials is of great significance for reducing electromagnetic pollution.Here,an emulsion-based self-assembly technique and ligand carbonization treatment have been used to construct the Fe_(3)O_(4)@C supraparticles for the evaluation of EM performance.The Fe_(3)O_(4)@C supraparticles exhibit excellent EM absorption properties,which can achieve full coverage of X band from 6.52 GHz to 12.9 GHz at a sample thickness of 3 mm.Besides,the optimum EAB value of Fe_(3)O_(4)@C supraparticles is up to 8.55 GHz from 9 to 18 GHz at a sample thickness of 2.5 mm.The Fe_(3)O_(4)@C supraparticles with superlattice structure will have potential development prospects in the application of broadband absorption. | Li Su Jiaxin Ma Fangzhou Zhang Yuchi Fan Wei Luo Lianjun Wang Wan Jiang Jianping Yang | 2021 | Journal of Materiomics2021,7,1: | 2 |
| 3 | SUSTAINABLE SUGARCANE CROPPING IN CHINA显示文摘Demand for sugar is projected to grow in China for the foreseeable future.However,sugarcane production is unlikely to increase due to increasing production cost and decreasing profit margin.The persisting sugarcane yield plateau and the current cropping system with fertilizer overuse,soil acidification and pests and diseases remain the major productivity constraints.Sugarcane agriculture supports the livelihood of about 28 million farmers in South China;hence,sustaining it is a socioeconomic imperative.More compellingly,to meet the ever-increasing Chinese market demand,annual sugar production must be increased from the current 10 Mt to 16 Mt by 2030 of which 80% to 90% comes from sugarcane.Therefore,increasing sugar yield and crop productivity in an environmentally sustainable way must be a priority.This review examines the current Chinese sugarcane production system and discuss options for its transition to a green,sustainable cropping system,which is vital for the long-term viability of the industry.This analysis shows that reducing chemical inputs,preventing soil degradation,improving soil health,managing water deficit,provision of clean planting material,and consolidation of small farm holdings are critical requirements to transform the current farming practices into an economically and environmentally sustainable sugarcane cropping system. | Ting LUO Prakash LAKSHMANAN Zhongfeng ZHOU Yuchi DENG Yan DENG Linsheng YANG Dongliang HUANG Xiupeng SONG Xihui LIU Wen-Feng CONG Jianming WU Xinping CHEN Fusuo ZHANG | 2022 | Frontiers of Agricultural Science and Engineering2022,9,2: | 1 |
| 4 | Facile synthesis of mesoporous WO3@graphene aerogel nanocomposites for low-temperature acetone sensing显示文摘Nanocomposites constructed by combining mesoporous metal oxides and graphene have received tremendous attention in wide fields of catalysis,energy storage and conversion,gas sensing and so on.Herein,we present a facile interface-induced co-assembly process to synthesize the mesoporous W03@graphene aerogel nanocomposites(denoted as mW03@GA),in which graphene aerogel(GA) was used as a macroporous substrate,mesoporous W03 was uniformly coated on both sides of graphene sheets through a solvent evaporation-induced self-assembly(EISA) strategy using diblock copolymer poly(ethylene oxide)-b-polystyrene(PEO-b-PS) as a template.The resultant mW03@GA nanocomposites possess well-interconnected macroporous graphene networks covered by mesoporous W03 layer with a uniform pore size of 19 nm,high surface area of 167 m^2/g and large pore volume of 0.26 cm^3/g.The gas sensing performance of mW03@GA nanocomposites toward acetone and other gases was studied,showing a high selectivity and great response to acetone at low temperature of 150℃,which could be developed as a promising candidate as novel sensors for VOCs detection. | Tao Zhao Yuan Ren Guangyou Jia Yuye Zhao Yuchi Fan Jianping Yang Xin Zhang Wan Jiang Lianjun Wang Wei Luo | 2019 | Chinese Chemical Letters2019,30,12: | 1 |

| 6 | High performance lithium-sulfur batteries by facilely coating a conductive carbon nanotube or graphene layer显示文摘Lithium sulfur(Li-S) batteries are regarded as promising candidates for next-generation rechargeable batteries. However, the insulation characteristic of sulfur and severe polysulfide dissolution hindered their development. We presented a facile approach to fabricate Li-S batteries by coating commercial carbon nanotube or graphene slurries on normal sulfur cathode electrode to construct a dual-layer cathode electrode. The conductive CNT or graphene layer could not only improve the conductivity of sulfur cathode, but also suppress the polysulfide diffusion. The CNT@S cathode delivered a high reversible capacity of 740 mAh/g over 300 cycles at 1 C and 870 mAh/g over 100 cycles at 0.2 C. Furthermore, this strategy could be realized on the commercial product line of lithium-ion batteries, which made it possible to large-scale produce Li-S batteries. | Yuchi Yang Chen Chen Jianhua Hu Yonghui Deng Yi Zhang Dong Yang | 2018 | Chinese Chemical Letters2018,29,12: | 1 |
| 7 | A confined micro-reactor with a movable Fe_(3) O_(4) core and a mesoporous TiO_(2) shell for a photocatalytic Fenton-like degradation of bisphenol A显示文摘Photocatalysis and Fenton process are two primary and promising advanced oxidation processes to degrade organic pollutants.However,the practical applications of single photocatalysis and Fenton process are still limited.Introducing one of them into another to form a combined photocatalytic Fentonlike system has shown great potential but still faces challenges in designing a well-tailored catalyst.Herein,a confined photocatalytic Fenton-like micro-reactor catalyst with a movable Fe_(3) O_(4) core and a mesoporous TiO_(2) shell has been constructed via a successive Stober coating strategy,followed by an ultrasound assisted etching method.The resulting micro-reactor possesses well-defined yolk-shell structures with unifo rm mesopores(~4 nm),a large Brunauer-Emmett-Teller(BET) surface area(~166.7 m^(2)/g),a high pore volume(~0.56 cm^(3)/g) and a strong magnetization(~51 emu/g),as well as tunable reactor sizes(20-90 nm).When evaluated for degrading bisphenol A under solar light in the presence of peroxymo no sulfate,the micro-reactor exhibits a superior catalytic degradation perfo rmance with a high magnetic separation efficiency and an excellent recycle ability.The outstanding performance can be attributed to its unique textual structure,which leads to a great syne rgistic effect from the photocatalytic and Fenton-like process.This study gives an important insight into the design and synthesis of an advanced micro-reactor for a combined advanced oxidation processes(AOPs). | Pengpeng Qiu Tao Zhao Xiaohang Zhu Binota Thokchom Jianping Yang Wan Jiang Lianjun Wang Yuchi Fan Xiaopeng Li Wei Luo | 2021 | Chinese Chemical Letters2021,32,4: | 1 |
| 8 | In vitro anther culture and Agrobacterium-mediated transformation of the AP1 gene from Salix integra Linn. in haploid poplar(Populus simonii × P. nigra)显示文摘A reliable,efficient anther culture system,the dominant technique for generating haploid plants in breeding programs,that can be used for generating transgenic poplar plants has been needed.In the present study,therefore,an anther culture system was developed using isolated mid-and late-uninucleate anthers of poplar(Populus simonii x P.nigra).From a combination of SSR and ploidy analyses,six double haploid and two haploid lines were characterized from 86 plants grown from 16 regenerated anther cultured lines.After 48 months of development,two plant lines from the regenerated plants maintained their haploid level in vitro for over 2 years.A number of haploid plants from the different lines weretransferred to soil.The leaves of these transplants were then used as explants for transformation with the APETALA1(AP1) gene using Agrobacterium tumefaciens.Overexpression of AP1 in haploid poplar induced early flowering with obvious petals when ectopically expressed.To our knowledge,this is the first report on changes in flowering time in AP1-trangenic poplar,which is important for elucidating the regulatory mechanism of tree flower development. | Jingli Yang Kun Li Chunyan Li Junxiu Li Bo Zhao Wei Zheng Yuchi Gao Chenghao Li | 2018 | Journal of Forestry Research2018,29,2: | 1 |
| 9 | An Investigation Report on Production Conditions of Sugarcane in Guangxi in 2016显示文摘To predict and assess production conditions of sugarcane in Guangxi in 2016,by using methods of field survey and data collection,the seedling situation,breed structure,planting area,planting period,plant diseases and insect pests of sugarcane in six major sugarcane producing cities of Guangxi were surveyed. The results show that the overall situation of sugarcane seedlings in Guangxi in 2016 became slightly worse than that in 2015,but there were enough good sugarcane seedlings in 2016. The dead heart rate of sugarcane decreased in most sugarcane regions from 2015 to 2016,that is,the comprehensive control of borers gave initial results; the smut infection rate of sugarcane rose from 2015 to 2016 and tended to increase. The situation of decrease in the planting area of sugarcane in three consecutive years was controlled,and the planting area of sugarcane increased slightly from 2015 to 2016. Due to the construction of ' double high' bases,the breed variety of sugarcane in Guangxi was improved further in 2016. It is necessary to strengthen field management and conduct chemical weeding,prevention and control of borers and aphids in the later period in time. | Yuchi DENG Weizan WANG RonghuaZHANG Shiyun TANG Shanhai LIN Qiang LIANG Weixing DUAN Xiang LI Guoying LU Shijian HAN Youzong HUANG Yebin YANG Yanni HUANG Lunwang WANG | 2017 | Asian Agricultural Research2017,9,6: | 0 |
| 10 | Enhanced photodetector performance of black phosphorus by interfacing with chiral perovskite显示文摘Heterogeneous stackings of two-dimensional(2D)semiconductors and halide perovskites have attracted much attention owing to their respective superior optoelectronic properties.Black phosphorus(BP),as a unique 2D member with narrow bandgap,high mobility,and strong anisotropy,has never been combined with 2D layered perovskites.Herein,we construct a new BP-based van der Waals heterostructure combing with 2D chiral hybrid perovskite(i.e.,(MBA)_(2)PbI_(4))for promoting the performance and enriching the functionalities of BP.A series of BP characteristics,including carrier mobility,photoresponsivity,and polarization sensitivity,are synergistically enhanced when interfacing with(MBA)_(2)PbI_(4).For instance,the photodetector responsivity and photogain of BP in heterostructures are boosted by almost one order of magnitude with respect to BP alone,which is more obvious under excitation above the bandgap of perovskite.This is because the interfacing perovskite provides an inflow of numerous photogenerated carriers to BP,to reinforce the charge carrier transfer,separation,and transport processes.Additionally,the ability of both linearly and circularly polarized photodetection can be integrated into the BP/(MBA)_(2)PbI_(4)heterostructure.Our work sheds new insight on the heterostructure assembly for promising optoelectronic applications within 2D materials and perovskite families. | Yang Cao Congzhou Li Jie Deng Tong Tong Yuchi Qian Guixiang Zhan Xu Zhang Kaiyue HeHuifang Ma Junran Zhang Jing Zhou Lin Wang | 2022 | Nano Research2022,15,8: | 0 |

| 12 | A Survey Report on Sugarcane Production in Guangxi Zhuang Autonomous Region in 2013显示文摘In order to fully understand sugarcane production in Guangxi in 2013,the sample survey combined with data collection and field survey was carried out in sugarcane production areas in Nanning,Hechi,Liuzhou,Chongzuo,Baise and Laibin from May 28 to June 36 in2013. It was found that the sugarcane growing area in Guangxi in 2013 declined compared with that in 2012; the rate of emergence remained the same as previous year,and as for the plant number of plant crop and ratoon crop per hectare,there was a decline of 4000 and 2000 seedlings respectively compared with the figure in 2012; borer damage rate declined on the whole while the incidence of sugarcane smut increased.Due to the growth in the cost of planting,the growers were less enthusiastic for management. According to the findings,the fertilization and sugarcane field management should be accelerated; borer prevention work was also required,so as to reduce borer damage and dieback rate;the planting structure of varieties had to be adjusted and the cultivated area of ' Guitang' as a fine sugarcane variety should also be enlarged;meanwhile other active measures needed to be taken to prevent and control the outburst of pest attack in local areas. | Xiang LI Yangrui LI Yuchi DENG Lunwang WANG Liu YANG Weihua HUANG Qiang LIANG Ronghua ZHANG Guoying LU Shijian HAN Pingwu LIU Changning LI Cuifang YANG | 2014 | Asian Agricultural Research2014,6,12: | 0 |
| 13 | A REVIEW ON ARTERY WALL SEGMENTATION TECHNIQUES AND INTIMA-MEDIA THICKNESS MEASUREMENT FOR CAROTID ULTRASOUND IMAGES显示文摘Stroke and heart attack,which could be led by a kind of cerebrovascular and cardiovascular disease named as atherosclerosis,would seriously cause human morbidity and mortality.It is important for the early stage diagnosis and monitoring medical intervention of the atherosclerosis.Carotid stenosis is a classical atherosclerotic lesion with vessel wall narrowing down and accumulating plaques burden.The carotid artery of intima-media thickness(IMT)is a key indicator to the disease.With the development of computer assisted diagnosis technology,the imaging techniques,segmentation algorithms,measurement methods,and evaluation tools have made considerable progress.Ultrasound imaging,being real-time,economic,reliable,and safe,now seems to become a standard in vascular assessment methodology especially for the measurement of IMT.This review firstly attempts to discuss the clinical relevance of measurements in clinical practice at first,and then followed by the challenges that one has to face when approaching the segmentation of ultrasound images.Secondly,the commonly used methods for the IMT segmentation and measurement are presented.Thirdly,discussion and evaluation of different segmentation techniques are performed.An overview of summary and future perspectives is given finally. | XIN YANG WANJI HE KAITONG LI JIAOYING JIN XUMING ZHANG MING YUCHI MINGYUE DING | 2012 | Journal of Innovative Optical Health Sciences2012,5,1: | 0 |
| 14 | Diagnosis of indirectly driven double shell targets with point-projection hard x-ray radiography显示文摘We present an application of short-pulse laser-generated hard x rays for the diagnosis of indirectly driven double shell targets. Coneinserted double shell targets were imploded through an indirect drive approach on the upgraded SG-II laser facility. Then, based on thepoint-projection hard x-ray radiography technique, time-resolved radiography of the double shell targets, including that of their near-peakcompression, were obtained. The backlighter source was created by the interactions of a high-intensity short pulsed laser with a metalmicrowire target. Images of the target near peak compression were obtained with an Au microwire. In addition, radiation hydrodynamicsimulations were performed, and the target evolution obtained agrees well with the experimental results. Using the radiographic images, arealdensities of the targets were evaluated. | Chao Tian Minghai Yu Lianqiang Shan Fengjuan Wu Bi Bi Qiangqiang Zhang Yuchi Wu Tiankui Zhang Feng Zhang Dongxiao Liu Weiwu Wang Zongqiang Yuan Siqian Yang Lei Yang Zhigang Deng Jian Teng Weimin Zhou Zongqing Zhao Yuqiu Gu Baohan Zhang | 2024 | Matter and Radiation at Extremes2024,9,2: | 0 |
| 15 | Commissioning experiment of the high-contrast SILEX-Ⅱ multi-petawatt laser facility显示文摘The results of a commissioning experiment on the SILEX-Ⅱlaser facility(formerly known as CAEP-PW)are reported.SILEX-Ⅱis a complete optical parametric chirped-pulse amplification laser facility.The peak power reached about 1 PWin a 30 fs pulse duration during the experiment.The laser contrast was better than 1010 at 20 ps ahead of the main pulse.In the basic laser foil target interaction,a set of experimental data were collected,including spatially resolved x-ray emission,the image of the coherent transition radiation,the harmonic spectra in the direction of reflection,the energy spectra and beam profile of accelerated protons,hot-electron spectra,and transmitted laser energy fraction and spatial distribution.The experimental results show that the laser intensity reached 531020 W/cm^(2) within a 5.8μm focus(FWHM).Significant laser transmission did not occur when the thickness of theCHfoil was equal to or greater than 50 nm.The maximum energy of the accelerated protons in the target normal direction was roughly unchanged when the target thickness varied between 50 nm and 15μm.The maximum proton energy via the target normal sheath field acceleration mechanism was about 21 MeV.We expect the on-target laser intensity to reach 10^(22) W/cm^(2) in the near future,after optimization of the laser focus and upgrade of the laser power to 3 PW. | Wei Hong Shukai He Jian Teng Zhigang Deng Zhimeng Zhang Feng Lu Bo Zhang Bin Zhu Zenghai Dai Bo Cui Yuchi Wu Dongxiao Liu Wei Qi Jinlong Jiao Faqiang Zhang Zuhua Yang Feng Zhang Bi Bi Xiaoming Zeng Kainan Zhou Yanlei Zuo Xiaojun Huang Na Xie Yi Guo Jingqin Su Dan Han Ying Mao Leifeng Cao Weimin Zhou Yuqiu Gu Feng Jing Baohan Zhang Hongbo Cai Minqing He Wudi Zheng Shaoping Zhu Wenjun Ma Dahui Wang Yinren Shou Xueqing Yan Bin Qiao Yi Zhang Congling Zhong Xiaohui Yuan and Wenqing Wei | 2021 | Matter and Radiation at Extremes2021,6,6: | 0 |
| 16 | Comparative DNA-methylome and transcriptome analysis reveals heterosis-and polyploidy-associated epigenetic changes in rice显示文摘Heterosis and polyploidy have an overwhelming influence on plant evolution.Recently,polyploid rice hybrids have been used to breed new rice varieties because they combine the advantages of both heterosis and polyploidy.In this study,we generated six rice lines:autotetraploid rice hybrids and their autotetraploid parents,diploid donors,and hybrids of the diploid donors.To investigate the molecular mechanism controlling the effects of both hybridization and polyploidization,we performed bisulfite and RNA sequencing on young panicles at the pollen meiosis stage to compare the DNA metabolomes and transcriptomes among the six rice lines.The hybrids lines were hypermethylated compared to their corresponding parents and the autotetraploid lines showed globally increased DNA methylation of their transposable elements compared to the diploid donors.The alteration in DNA methylation level corresponded to the differential gene expressions among the rice genotypes,suggesting that methylation changes induced by polyploidization and hybridization may affect gene expression.Groups of gene candidates were identified that may be associated with heterosis and polyploidy.Our results provide DNA information that can be used to investigate epigenetic modification during heterosis and polyploidy in rice. | Xiaolan Rao Jun Ren Wei Wang Rongrong Chen Qian Xie Yanqing Xu Dongmei Li Zhaojian Song Yuchi He Detian Cai Pingfang Yang Shiyou Lyu Li Li Wei Liu Xianhua Zhang | 2023 | The Crop Journal2023,11,2: | 0 |
| 17 | Effect and Analysis of Mechanized Production on Ratooning Ability of Guitang 47显示文摘[Objectives] This study was conducted to explore the effect of machine harvesting on ratooning ability of Guitang 47, and to provide basis for mechanized production of Guitang 47. [Methods] On the basis of mechanized planting and management of newly planted sugarcane Guitang 47, a comparative test of machine harvesting and manual harvesting was conducted, during which the plant generation rate, sugarcane yield, sucrose content and related agronomic traits of ratoon cane were continuously investigated in two years after machine harvesting of the newly planted sugarcane. [Results] There were no significant differences in the plant generation rate, plant height, stalk diameter, millable cane, sugarcane yield and sucrose content from manual harvesting of Guitang 47 in the first and second years after machine harvesting. In the second year after machine harvesting, the yields of ratoon cane and the sugar content reached 101.70 and 15.32 t/hm^2, respectively, which were equivalent to those of manual harvesting. [Conclusions] Guitang 47 has strong ratooning ability and lodging resistance and strong resistance to rolling and crushing, and is adaptive to full mechanized production. It should be promoted and accelerated in sugarcane areas lacking labor to reduce costs and increase benefits. | Lunwang WANG Yuchi DENG Fang TAN Shiyun TANG Hairong HUANG Yan JING Rongzhong YANG | 2020 | Agricultural Biotechnology2020,9,1: | 0 |
