| 1 | Porous bowl-shaped VS2 nanosheets/graphene composite for high-rate lithium-ion storage显示文摘Two-dimensional (2D) layered vanadium disulfide (VS2) is a promising anode material for lithium ion batteries (LIBs) due to the high theoretical capacity.However,it remains a challenge to synthesize monodispersed ultrathin VS2 nanosheets to realize the full potential.Herein,a novel solvothermal method has been developed to prepare the monodispersed bowl-shaped NH3-inserted VS2 nanosheets (VS2).The formation of such a unique structure is caused by the blocked growth of (001) or (002) crystal planes in combination with a ripening process driven by the thermodynamics.The annealing treatment in Ar/H2creates porous monodispersed VS2(H-VS2),which is subsequently integrated with graphene oxide to form porous monodispersed H-VS2/rGO composite coupled with a reduction process.As an anode material for LIBs,H-VS2/rGO delivers superior rate performance and longer cycle stability:a high average capacity of 868/525 mAh g^-1 at a current density of 1/10 A g^-1;a reversible capacity of 1177/889 mAh g^-1 after 150/500 cycles at 0.2/1 A g^-1.Such excellent electrochemical performance may be attributed to the increased active sites available for lithium storage,the alleviated volume variations and the shortened Li-ion diffusion induced from the porous structure with large specific surface area,as well as the protective effect from graphene nanosheets. | Daxiong Wu Caiyun Wang Mingguang Wu Yunfeng Chao Pengbin He Jianmin Ma | 2020 | Journal of Energy Chemistry2020，29，4： | 11 |

| 3 | Hepatic encephalopathy complicated with hyponatremia and acid-base disturbance and its prognosis显示文摘Objective:To improve the diagnosis and therapeutic effect of occurrence and development of hyponatremia and disorder of acid-base balance among patients with hepatic encephalopathy(HE) by elucidating the regularity and mechanism,as well as its influence on prognosis.Methods:327 HE patients admitted to our hospital from January 1990 to June 2010 were enrolled.Meanwhile 316 patients hospitalized in the medical department of the same hospital were chosen as the control group.Patients in both groups were given the same methods to measure arterial blood gas parameters(pH value,PaCO2,[HCO3-],TCO2,BE and SaO2),blood biochemistry([Na+],[K+],[Cl-]),liver function,kidney function and blood glucose,serum sodium,and thereupon tocalculate the anion gap(AG) and the potential [HCO3-],and acid-base balance disorder.Results:Among the 327 HE patients,hyponatremia was found in 188 cases(57.4%),of whom 132 patients died(70.2%).While among the 316 patients in control group,68 presented with hyponatremia(21.5%),and 19 died(27.9%).The incidence and mortality were significantly different between the two groups(P<0.001).All the 327 patients presented with different degrees of acid-base balance disorder and 178 died(54.4%),in whom 164(50.2%) belonged to simple acid-base balance disorder and 74(45.1%) died,136(41.6%) were dual acid-base balance disorder and 80(58.8%) died,27(8.2%) were triple acid-base disturbance and 24(88.9%) died.Whereas in the control group only 83 patients(26.2%) were recognized as simple and dual acid-base balance disorder,and 18(21.7%) died.There was higher incidence of acid-base balance disorder and mortality rate in HE group than control one(P<0.001).Conclusion:Hyponatremia is valuable to judge HE patients' prognosis.The key parameters in the judgment and evaluation on acid-base balance disorder among HE patients are the change of pH values and serum electrolyte values.When pH value ≤ 7.30 or > 7.55,it generally suggests a poor prognosis. | Ren Chengshan Wang Lei Zhao Xiaoyan Yang Shiming Zhang Yanqi Wang Xiwen Bo Jianying Zhang Pengbin Guo Hong Ling Xianlong Li Yihui Da Siping Xie Xia Ren Wei Li Chunhua Qian Guisheng | 2012 | Journal of Medical Colleges of PLA(China)2012，27，3： | 3 |
| 4 | Using unmanned aerial vehicles with thermal-image acquisition cameras for animal surveys:a case study on the Sichuan snub-nosed monkey in the Qinling Mountains显示文摘Following significant developments in technology,alternative devices have been applied in fieldwork for animal and plant surveys.Thermal-image acquisition cameras installed on unmanned aerial vehicles(UAVs)have been used in animal surveys in the wilderness.This article demonstrates an example of how UAVs can be used in high mountainous regions,presenting a case study on the Sichuan snub-nosed monkey with a detection rate of 65.19%for positive individual identification.It also presents a model that can prospectively predict population size for a given animal species,which is based on combined initial work using UAVs and traditional surveys on the ground.A great potential advantage of UAVs is significantly shortening survey procedures,particularly for areas with high mountains and plateaus,such as the Himalayas,the Qinghai-Tibet Plateau,Hengduan Mountains,the Yunnan-Gui Plateau and Qinling Mountains in China,where carrying out a traditional survey is extremely difficult,so that species and population surveys,particularly for critically endangered animals,are largely absent.This lack of data has impacted the management of endangered animals as well as the formulation and amendment of conservation strategies. | Gang HE Haitao YANG Ruliang PAN Yewen SUN Pengbin ZHENG Jinghua WANG Xuelin JIN Jingjie ZHANG Baoguo LI Songtao GUO | 2020 | Integrative Zoology2020，15，1： | 2 |

| 8 | Piezoelectric ceramics with high piezoelectricity and broad temperature usage range显示文摘There is a general observation that the Curie temperature and piezoelectric property of the ferroelectric ceramics can be enhanced only at the expense of each other,i.e.,higher piezoelectricity,lower Curie temperature,thus,limits their applications over broad temperature range.In this research,Sm-modified 0.15 Pb(Mg_(1/3)Nb_(2/3))O_(3)-(0.85-x)PbZrO_(3)-xPbTiO_(3) ceramics have been studied,where excellent piezoelectric coefficients d33¼720 pC/N,d_(33)*=950 pm/V and high Curie temperature T_(C)=293℃ were simultaneously achieved for x=0.42 composition by designing the morphotropic phase boundary(MPB)with local structural heterogeneity.Of particular significance is that a high thermal stability was observed with piezoelectric variation below 20%with temperature up to 280℃,demonstrating that the x=0.42 composition is a good candidate for piezoelectric application over broad temperature range where high temperature stability is required.This work provides a good paradigm for designing highperformance piezoelectric ceramics with high thermal stability via a combination of MPB and local structural heterogeneity. | Qinghu Guo Fei Li Fangquan Xia Pengbin Wang Xiaoyi Gao Hua Hao Hanxing Liu Huajun Sun Shujun Zhang | 2021 | Journal of Materiomics2021，7，4： | 0 |

| 10 | Computer-Assisted Path Planning for Minimally Invasive Vascular Surgery显示文摘Path planning assisted by two-dimensional medical images is an essential part of minimally invasive diagnosis and treatment for cardiovascular diseases. Due to the complex background of angiography images and intricate vascular structure with multi-branch and stenoses,creating accurate pathways from angiography image is a challenge task. We present a new path planning methodology based on angiography medical images using the steady fluid dynamics. Our novel approach is useful in many medical applications, such as for computer-assisted medical images analysis and the follow-on image-guided interventions. A graph-cuts based energy function was applied to the vessel segmentation of angiography images in order to obtain boundary information. We have adopted Finite volume method(FVM) to simulate the Newtonian fluid inside the segmented blood vessels, and a set of isobars under the steady fluid condition are obtained by Meandering Triangles algorithm. The selected center points of isobars are organized to generate the directed vessels-tree, from which the vascular stenoses are automatically detected and the final surgical path is generated with branches. Our method can be used for quantitative path analysis, and we show experimental results to demonstrate that the versatility and applicability of the algorithm in obtaining single-pixel surgical path with good performance, high accuracy and less manual interventions, especially it is robust on complex vascular structures. | HUANG Dongjin TANG Pengbin WANG Yin LI Hejuan TANG Wen DING Youdong | 2018 | Chinese Journal of Electronics2018，27，6： | 0 |

| 14 | Unveiling the planar deformation mechanisms for improved formability in pre-twinned AZ31 Mg alloy sheet at warm temperature显示文摘To investigate the role of pre-twins in Mg alloy sheets during warm planar deformation, the stretch forming is conducted at 200 ℃. Results suggest the formability of the pre-twinned AZ31 Mg alloy sheet is enhanced to 11.30 mm. The mechanisms for the improved formability and the deformation behaviors during the planar stretch forming are systematically investigated based on the planar stress states. The Schmid factor for deformation mechanisms are calculated, the results reveal that planar stress states extremely affect the Schmid factor for {10-12}twinning. The detwinning is activated and the prismatic slip is enhanced in the pre-twinned sheet, especially under the planar extension stress state in the outer region. Consequently, the thickness-direction strain is accommodated better. The dynamic recrystallization(DRX) type is continuous DRX(CDRX) regardless of the planar stress state. However, the CDRX degree is greater under the planar extension stress state.Some twin lattices deviate from the perfect {10-12} twinning relation due to the planar compression stress state and the CDRX. The basal texture is weakened when the planar stress state tends to change the texture components. | Xiaohuan Pan Lifei Wang Pengbin Lu Hua Zhang Guangsheng Huang Liuwei Zheng Bin Xing Weili Cheng Hongxia Wang Wei Liang Kwang Seon Shin | 2023 | Journal of Magnesium and Alloys2023，11，12： | 0 |
