| 1 | Risk factors for the incidence of apoplexy in pituitary adenoma: a single-center study from southwestern China显示文摘Background:Although the incidence and clinical manifestations of pituitary apoplexy were reported by a few researches,the results are not consistent.This study aimed to explore the risk factors associated with an incidence of apoplexy in pituitary adenomas.Methods:The clinical information of 843 patients with pituitary adenoma from the Department of Neurological Surgery,1st Affiliated Hospital of Kunming Medical University,was reviewed.The incidence,clinical manifestation,and potential risk factors for pituitary apoplexy were analyzed by a case-control study.Results:In total,121 patients(14.4%)with macroadenoma were suffered from pituitary apoplexy.Headache,vomiting,and visual impairment are the top 3 symptoms for the pituitary apoplexy.Logistic regression results showed that the hypertension(hypertension vs non-hypertension OR=2.765,95%CI:1.41~5.416),tumor type(negative staining vs.positive staining,OR=1.501,95%CI:1.248~5.235),and tumor size(diameter>2 cm vs.diameter≤2 cm,OR=3.952,95%CI:2.211~7.053)are independent factors associated with pituitary apoplexy.Conclusion:Our results indicate that the risk factors for the incidence of pituitary apoplexy depend mainly on properties of the tumor itself(tumor size and pathologic type)and the blood pressure of patients. | Yao Li Yuan Qian Yisheng Qiao Xiaoxiang Chen Jiaotian Xu Chao Zhang Wei Wang Junjun Li Xingli Deng | 2020 | Chinese Neurosurgical Journal2020，6，4： | 3 |
| 2 | Reconfigurable photovoltaic effect for optoelectronic artificial synapse based on ferroelectric p-n junction显示文摘Neuromorphic machine vision has attracted extensive attention on wide fields.However,both current and emerging strategies still suffer from power/time inefficiency,and/or low compatibility,complex device structure.Here we demonstrate a driving-voltage-free optoelectronic synaptic device using non-volatile reconfigurable photovoltaic effect based on MoTe_(2)/α-In_(2)Se_(3) ferroelectric p-n junctions.This function comes from the non-volatile reconfigurable built-in potential in the p-n junction that is related to the ferroelectric polarization inα-In_(2)Se_(3).Reconfigurable rectification behavior and photovoltaic effect are demonstrated firstly.Notably,the figure-of-merits for photovoltaic effect like photoelectrical conversion efficiency non-volatilely increases more than one order.Based on this,retina synapse-like vision functions are mimicked.Optoelectronic short-term and long-term plasticity,as well as basic neuromorphic learning and memory rule are achieved without applying driving voltage.Our work highlights the potential of ferroelectric p-n junctions for enhanced solar cell and low-power optoelectronic synaptic device for neuromorphic machine vision. | Yanrong Wang Feng Wang Zhenxing Wang Junjun Wang Jia Yang Yuyu Yao Ningning Li Marshet Getaye Sendeku Xueying Zhan Congxin Shan Jun He | 2021 | Nano Research2021，14，11： | 2 |
| 3 | Radiation-hardened property of single-walled carbon nanotube film-based field-effect transistors under low-energy proton irradiation显示文摘Strong C-C bonds,nanoscale cross-section and low atomic number make single-walled carbon nanotubes(SWCNTs)a potential candidate material for integrated circuits(ICs)applied in outer space.However,very little work combines the simulation calculations with the electrical measurements of SWCNT field-effect transistors(FETs),which limits further understanding on the mechanisms of radiation effects.Here,SWCNT film-based FETs were fabricated to explore the total ionizing dose(TID)and displacement damage effect on the electrical performance under low-energy proton irradiation with different fluences up to 1×1015 p/cm2.Large negative shift of the threshold voltage and obvious decrease of the on-state current verified the TID effect caused in the oxide layer.The stability of the subthreshold swing and the off-state current reveals that the displacement damage caused in the CNT layer is not serious,which proves that the CNT film is radiation-hardened.Specially,according to the simulation,we found the displacement damage caused by protons is different in the source/drain contact area and channel area,leading to varying degrees of change for the contact resistance and sheet resistance.Having analyzed the simulation results and electrical measurements,we explained the low-energy proton irradiation mechanism of the CNT FETs,which is essential for the construction of radiation-hardened CNT film-based ICs for aircrafts. | Xiaorui Zhang Huiping Zhu Song’ang Peng Guodong Xiong Chaoyi Zhu Xinnan Huang Shurui Cao Junjun Zhang Yunpeng Yan Yao Yao Dayong Zhang Jingyuan Shi Lei Wang Bo Li Zhi Jin | 2021 | Journal of Semiconductors2021，42，11： | 2 |
| 4 | Carboniferous integrative stratigraphy and timescale of China显示文摘The Carboniferous period lasted about 60 Myr, from ~358.9 Ma to ~298.9 Ma. According to the International Commission on Stratigraphy, the Carboniferous System is subdivided into two subsystems, i.e., Mississippian and Pennsylvanian, including 6 series and 7 stages. The Global Stratotype Sections and Points(GSSPs) of three stages have been ratified, the Tournaisian, Visean, and Bashkirian stages. The GSSPs of the remaining four stages(i.e., the Serpukhovian, Moscovian,Kasimovian, and Gzhelian) have not been ratified so far. This paper outlines Carboniferous stratigraphic subdivision and correlation on the basis of detailed biostratigraphy mainly from South China, and summarizes the Carboniferous chronostratigraphic framework of China. High-resolution biostratigraphic study reveals 37 conodont zones, 24 foraminiferal(including fusulinid) zones, 13 ammonoid zones, 10 brachiopod zones, and 10 rugose coral zones in the Carboniferous of China. The biostratigraphic framework based on these biozones warrants the precise correlation of regional stratigraphy of China(including2 subsystems, 4 series, and 8 stages) to that of the other regions globally. Meanwhile, the Carboniferous chemo-, sequence-,cyclo-, and event-stratigraphy of China have been intensively studied and can also be correlated worldwide. Future studies on the Carboniferous in China should focus on(1) the correlation between shallow-and deep-water facies and between marine and continental facies,(2) high-resolution astronomical cyclostratigraphy, and(3) paleoenvironment and paleoclimate analysis based on geochemical proxies such as strontium and oxygen isotopes, as well as stomatal indices of fossil plants. | Xiangdong WANG Keyi HU Wenkun QIE Qingyi SHENG Bo CHEN Wei LIN Le YAO Qiulai WANG Yuping QI Jitao CHEN Zhuoting LIAO Junjun SONG | 2019 | Science China Earth Sciences2019，62，1： | 2 |

| 9 | Effect of semi-continuous water washing on the combustion behaviors of agricultural organic solid waste显示文摘Combustion of agricultural organic solid waste(AOSW)was an ideal solution for their resource utilization in view of their massive annual production and great potential for reduction of fossil fuel utilization.However,high alkali and alkaline earth metals(AAEMs)content in the feedstock can arose severe fouling and slagging issues and thus prohibiting its vast utilization.In this study,a semi-continuous water washing method was proposed to preliminarily remove AAEMs from agricultural organic solid waste and its effects on the combustion behaviors of washed solid product were investigated.Results showed that the combustion index S were improved to 2.63×10-6,over 68%of the total ashes were removed from the cotton stalk,and 96.3%,89.0%and 74.7%of K,Na and Mg were effectively removed,respectively.Moreover,the softening temperature of low temperature ash from the washed sample was as high as 1450◦C,538◦C higher than the low temperature ash from the original sample;the base acid ratio and fouling index were improved from high slagging and fouling risk(1.7 and 90.8)of the original organic solid waste to low and medium risk(0.4 and 3.5),respectively.All these results signified the contributing effect of proposed semi-continuous water washing method on the combustion of agricultural organic solid waste.In a word,this study provided a promising method for fouling and slagging inhibition during the agricultural organic solid waste combustion. | Xiangxi Wang Zhenzhong Hu Jinrong Ma Linlin Yi Jian Li Yanfeng Cheng Jianfei Ma Na An Feng Wang Xian Li Junjun Yan Bo Wei Yue Li Guangqian Luo Hong Yao | 2023 | Carbon Resources Conversion2023，6，1： | 0 |
| 10 | Phosphorous-doped carbon nanotube/reduced graphene oxide aerogel cathode enabled by pseudocapacitance for high energy and power zinc-ion hybrid capacitors显示文摘The design and development of energy storage device with high energy/power density has become a research hotspot.Zinc-ion hybrid capacitors(ZHCs)are considered as one of the most promising candidates.However,the application of ZHCs is hindered by their low energy density at high power density due to the unsatisfactory cathode material.In this study,a novel 3D phosphorus-doped carbon nanotube/reduced graphene oxide(P-CNT/rGO)aerogel cathode is synthesized through a synergistic modification strategy of CNT insertion and P doping modification combined with 3D porous design.The as-obtained P-CNT/rGO aerogel cathode manifests significantly increased surface aera,expanded interlayer spacing,and enhanced pseudocapacitance behavior,thus leading to significantly enhanced specific capacitance and superb ions transport performance.The as-assembled ZHC based on P-CNT/rGO cathode delivers a superior energy density of 42.2 Wh/kg at an extreme-high power density of 80 kW/kg and excellent cycle life.In-depth kinetic analyses are undertaken to prove the enhanced pseudocapacitance behavior and exceptional power output capability of ZHCs.Furthermore,the reaction mechanism of physical and chemical adsorption/desorption of electrolyte ions on the P-CNT/rGO cathode is revealed by systematic ex-situ characterizations.This work can provide a valuable reference for developing advanced graphene-based cathode for high energy/power density ZHCs. | Junjun Yao Fuzhi Li Ruyi Zhou Chenchen Guo Xinru Liu Yirong Zhu | 2024 | Chinese Chemical Letters2024，35，2： | 0 |
| 11 | Copper-induced formation of heterostructured Co_(3)O_(4)/CuO hollow nanospheres towards greatly enhanced lithium storage performance显示文摘We report a facile template-free fabrication of heterostructured Co_(3)O_(4)/CuO hollow nanospheres using pre-synthesized Co/Cu-glycerate as conformal precursor.The introduction of copper nitrate in the solvothermal reaction system of glycerol/isopropanol/cobalt nitrate readily induces the conversion from solid Co-glycerate to hollow Co/Cu-glycerate nanospheres,and the effect of the Co/Cu atomic ratio on the structure evolution of the metal glycerates as well as their corresponding oxides were investigated.When examined as anode materials for lithium-ion batteries,the well-defined Co_(3)O_(4)/CuO hollow nanospheres with Co/Cu molar ratio of 2.0 demonstrate excellent lithium storage performance,delivering a high reversible capacity of 930 mAh/g after 300 cycles at a current density of 0.5 A/g and a stable capacity of 650 mAh/g after 500 cycles even at a higher current density of 2.0 A/g,which are much better than their counterparts of bare CuO and Co_(3)O_(4).The enhanced lithium storage performance can be attributed to the synergistic effect of the CuO and Co_(3)O_(4)heterostructure with hollow spherical morphology,which greatly enhances the charge/electrolyte transfer and effectively buffers the volume changes upon lithiation/delithiation cycling. | Junjun Zhang Huiying Lu Tianhao Yao Xin Ji Qingmiao Zhang Lingjie Meng Jianmin Feng Hongkang Wang | 2024 | Chinese Chemical Letters2024，35，2： | 0 |
| 12 | Enhancement of CH_(3)CO^(*) adsorption by editing d-orbital states of Pd to boost C–C bond cleavage of ethanol eletrooxidation显示文摘Improving the complete ethanol electrooxidation on Pd-based catalysts in alkaline media has drawn widely attention due to the high mass energy density.However,the weak adsorption energy of CH_(3)CO^(*) on Pd restricts the C–C bond cleavage.Inspired by the molecular orbital theory,we proposed the d-state-editing strategy to construct more unoccupied d-states of Pd for the enhanced interaction with CH_(3)CO^(*) to break C–C bonds.As expected,the reduced number of e_g electrons and more unoccupied d-states of Pd successfully formed on as-prepared porous Rh Au–Pd Cu nanosheets(PNSs).Theoretical calculations show that the optimized d-states of Rh Au–Pd Cu PNS can effectively improve the adsorption of CH_(3)CO^(*) and drastically reduce the energy barrier of C–C bond cleavage,thus boosting the complete oxidation of ethanol.The charge ratio of C_1 pathway on Rh Au–Pd Cu PNSs is 51.5%,more than 2 times higher than that of Pd NSs.Our finding provides an innovative perspective for the design of highly-efficient noble-based electrocatalysts. | Yuchen Qin Fengqi Wang Pei Liu Jinyu Ye Qian Wang Yao Wang Guangce Jiang Lijie Liu Pengfang Zhang Xiaobiao Liu Xin Zheng Yunlai Ren Junjun Li Zhicheng Zhang | 2024 | Science China Chemistry2024，67，2： | 0 |
| 13 | Morphological disruption and visual tuning alterations in the primary visual cortex in glaucoma(DBA/2J)mice显示文摘Glaucoma is a leading cause of irreve rsible blindness wo rldwide,and previous studies have shown that,in addition to affecting the eyes,it also causes abnormalities in the brain.However,it is not yet clear how the primary visual cortex(V1)is altered in glaucoma.This study used DBA/2J mice as a model for spontaneous secondary glaucoma.The aim of the study was to compare the electrophysiological and histomorphological chara cteristics of neurons in the V1between 9-month-old DBA/2J mice and age-matched C57BL/6J mice.We conducted single-unit recordings in the V1 of light-anesthetized mice to measure the visually induced responses,including single-unit spiking and gamma band oscillations.The morphology of layerⅡ/Ⅲneurons was determined by neuronal nuclear antigen staining and Nissl staining of brain tissue sections.Eighty-seven neurons from eight DBA/2J mice and eighty-one neurons from eight C57BL/6J mice were examined.Compared with the C57BL/6J group,V1 neurons in the DBA/2J group exhibited weaker visual tuning and impaired spatial summation.Moreove r,fewer neuro ns were observed in the V1 of DBA/2J mice compared with C57BL/6J mice.These findings suggest that DBA/2J mice have fewer neurons in the VI compared with C57BL/6J mice,and that these neurons have impaired visual tuning.Our findings provide a better understanding of the pathological changes that occur in V1 neuron function and morphology in the DBA/2J mouse model.This study might offer some innovative perspectives regarding the treatment of glaucoma. | Yin Yang Zhaoxi Yang Maoxia Lv Ang Jia Junjun Li Baitao Liao Jing’an Chen Zhengzheng Wu Yi Shi Yang Xia Dezhong Yao Ke Chen | 2024 | Neural Regeneration Research2024，19，1： | 0 |
