| 1 | Porous LiFePO_(4)/NiP Composite Nanospheres as the Cathode Materials in Rechargeable Lithium Ion Batteries显示文摘We report the synthesis of porous LiFePO4/NiP composite nanospheres and their application in rechargeable lithium-ion batteries.A simple one-step spraying technique was developed to prepare LiFePO_(4)/NiP composite nanospheres with an electrical conductivity 10^(3)-10^(4) times that of bulk particles of LiFePO_(4).Electrochemical measurements show that LiFePO_(4) nanospheres with a uniform loading of 0.86 wt%1.50 wt%NiP exhibit high discharge capacity,good cycling reversibility,and low apparent activation energies.The superior electrode performance of the as-prepared composite nanospheres results from the greatly enhanced electrical conductivity and porous structure of the materials. | Chunsheng Li Shaoyan Zhang Fangyi Cheng Weiqiang Ji Jun Chen | 2008 | Nano Research2008,1,3: | 12 |
| 2 | Porous V2O5 nanofibers as cathode materials for rechargeable aqueous zinc-ion batteries显示文摘Rechargeable aqueous zinc-ion batteries are recently gaining incremental attention because of low cost and material abundance, but their development is plagued by limited choice of cathode materials with satisfactory cycling performance. Here, we report a porous V2O5 nanofibers cathode with high Znstorage performance in an aqueous Zn(CF3SO3)2 electrolyte. We propose a reaction mechanism based on phase transition from orthorhombic V2O5 to zinc pyrovanadate on first discharging and reversible Zn^2+ (de)intercalation in the open-structured hosts during subsequent cycling. This open and stable architecture enables a high reversible capacity of 319 mAh g^-1 at 20 mAg^-1 and a capacity retention of 81% over 500 cycles. The remarkable electrochemical performance makes V2O5 a promising cathode for aqueous zinc-ion batteries. | Xuyong Chen Liubin Wang Hang Li Fangyi Cheng Jun Chen | 2019 | Journal of Energy Chemistry2019,28,11: | 7 |
| 3 | Real-time compensation of phase drift for phase-encoded quantum key distribution systems显示文摘Phase drift is an inherent problem in phase-encoded quantum key distribution(QKD) systems.The current active phase trackingand compensation solutions cannot satisfy the requirements of a system with nonlinearity in phase modulation.This paper presents a four-phase scanning method,which is based on the quantitative analysis of the quantum bit error rate(QBER) from phasedrift and the performance requirements of phase compensation.By obtaining the four interference fringes and adjusting the codingmatrix of the system,this method automatically calculates the accurate driving voltages for the phase modulator.The implementation and experimental tests show that the proposed method can compensate phase drift caused by environmental changes and thesystem's nonlinearity,and is applicable to large-scale QKD networks. | ZHANG LiJun WANG YongGang YIN ZhenQiang CHEN Wei YANG Yang ZHANG Tao HUANG DaJun WANG Shuang LI FangYi HAN ZhengFu | 2011 | Chinese Science Bulletin2011,56,22: | 6 |
| 4 | Low-temperature sintering and microwave dielectric properties of CaMg1−xLi2xSi2O6(x=0−0.3)ceramics显示文摘In this study, low-temperature fired CaMg1−xLi2xSi2O6 microwave dielectric ceramics were prepared via the traditional solid-state reaction method. In this process, 0.4 wt% Li2CO3-B2O3-SiO2-CaCO3-Al2O3 (LBSCA) glass was added as a sintering aid. The results showed that ceramics consisted of CaMgSi2O6 as the main phase. The second phases were CaSiO3 always existing and Li2SiO3 occurring at substitution content x > 0.05. Li+ substitution effectively lowered sintering temperature due to 0.4 wt% LBSCA and contributed to grain densification, and the most homogeneous morphology could be observed at x = 0.05. The effects of relative density, the second phase, and ionic polarizability on dielectric constant (εr) were investigated. The quality factor (Q × f) varied with packing fraction that concerned the second phase. Moreover, the temperature coefficient of the resonant frequency (τf) was influenced by MgO6 octahedral distortion and bond valence. Excellent dielectric properties of the CaMg1−xLi2xSi2O6 ceramic was exhibited at x = 0.05 with εr = 7.44, Q × f = 41,017 GHz (f = 15.1638 GHz), and τf = −59.3 ppm/°C when sintered at 900 °C. It had a good application prospect in the field of low-temperature co-fired ceramic (LTCC) substrate and devices. | Fangyi Huang Hua Su Yuanxun Li Huaiwu Zhang Xiaoli Tang | 2020 | Journal of Advanced Ceramics2020,9,4: | 6 |

| 6 | New method for controlling minimum length scales of real and void phase materials in topology optimization显示文摘Minimum length scale control on real and void material phases in topology optimization is an important topic of research with direct implications on numerical stability and solution manufacturability.And it also is a challenge area of research due to serious conflicts of both the solid and the void phase element densities in phase mixing domains of the topologies obtained by existing methods.Moreover,there is few work dealing with controlling distinct minimum feature length scales of real and void phase materials used in topology designs.A new method for solving the minimum length scale controlling problem of real and void material phases,is proposed.Firstly,we introduce two sets of coordinating design variable filters for these two material phases,and two distinct smooth Heaviside projection functions to destroy the serious conflicts in the existing methods(e.g.Guest Comput Methods Appl Mech Eng 199(14):123-135,2009).Then,by introducing an adaptive weighted 2-norm aggregation constraint function,we construct a coordinating topology optimization model to ensure distinct minimum length scale controls of real and void phase materials for the minimum compliance problem.By adopting a varied volume constraint limit scheme,this coordinating topology optimization model is transferred into a series of coordinating topology optimization sub-models so that the structural topology configuration can stably and smoothly changes during an optimization process.The structural topology optimization sub-models are solved by the method of moving asymptotes(MMA).Then,the proposed method is extended to the compliant mechanism design problem.Numerical examples are given to demonstrate that the proposed method is effective and can obtain a good 0/1 distribution final topology. | Xuanpei Rong Jianhua Rong Shengning Zhao Fangyi Li Jijun Yi Luo Peng | 2020 | Acta Mechanica Sinica2020,36,4: | 3 |

| 8 | Assessment of effective conservation of the Sichuan takin by giant panda reserves through functional zoning显示文摘The flagship species conservation strategy is widely practiced in nature reserves.However,few studies have quantitatively explored whether the current functional zoning adequately conserves the habitats of other species.To examine this problem,we selected the Tangjiahe,Xuebaoding,and Wanglang national nature reserves in southwest China and tested the protective efficiency of the giant panda(Ailuropoda melanoleuca)reserves on a local herbivore—Sichuan takin(Budorcas taxicolor tibetana)in functional zoning.We predicted that the habitat distribution of the Sichuan takin with Maxent and habitat suitability would be classified as very low,low,moderately,or highly suitable.We calculated the percentage of each type of habitat class across the core,buffer,and experimental zones in these reserves and introduced an economic index present value index to further assess the efficacy of the functional zoning in conserving the habitat of Sichuan takin.Our findings indicate that suitable habitat distributions of Sichuan takin are multicore and influenced by diverse variables in different nature reserves.The percentage of moderately suitable and highly suitable habitat in the core zone is 69%and 54%in Tangjiahe,76%and 75%in Wanglang,and 47%and 28%in Xuebaoding,respectively.The present value index of moderately and highly suitable habitat is 1.01 and 0.79(Tangjiahe),0.87 and 0.86(Wanglang),0.76 and 0.44(Xuebaoding),respectively.The efficiency of functional zoning on Sichuan takin seems lower than imagined in giant panda reserves,and species that have important impacts on local ecosystem need further estimation and greater focus. | Haiyang GAO Tianpei GUAN Di ZHU Wenwen LI Fangyi ZHOU Ding ZHAO Changlin LI Li ZHANG | 2020 | Integrative Zoology2020,15,6: | 2 |
| 9 | The predictive value of SS-16 in clinically diagnosed Parkinson’s disease patients:comparison with ^(99m)Tc-TRODAT-1 SPECT scans显示文摘Background:Dopamine transporter based imaging has high diagnostic performance in distinguishing patients with Parkinson’s disease(PD)from patients with non-Parkinsonian syndromes.Our previous study indicated that the“Sniffin’Sticks”odor identification test(SS-16)acts as a valid instrument for olfactory assessment in Chinese PD patients.The aim of the study was to compare the efficacy of the two methods in diagnosing PD.Methods:Fifty-two PD patients were involved in this study and underwent single photon emission computed tomography(SPECT)imaging using the labeled dopamine transporter radiotracer ^(99)mTc-TRODAT-1 to assess nigrostriatal dopaminergic function.Olfactory function was assessed with the“Sniffin’Sticks”odor identification test(SS-16)in all patients who received DAT-SPECT scanning.Statistical analysis(SPSS version 21)was carried out to determine the diagnostic accuracy of SS-16 as well as its correlation with ^(99)mTc-TRODAT-1 SPECT,its positive predictive value(PPV),and negative predictive value(NPV).Results:We identified a negative correlation between SS-16 and DAT SPECT(Kappa=0.269,p=0.004).By using the ^(99)mTc-TRODAT-1 uptake results as the gold standard,the sensitivity and specificity of SS-16 was 56.8 and 37.5%,respectively.Furthermore,the negative and positive predictive values were calculated as 13.6 and 83.3%,respectively.Conclusions:SS-16 would not be used as a diagnostic tool for early stage PD patients.Negative results of SS-16 would not exclude the diagnosis of PD.Further tests are needed for validation. | Wenyan Kang Fangyi Dong Dunhui Li Thomas J.Quinn Shengdi Chen Jun Liu | 2016 | Translational Neurodegeneration2016,5,1: | 2 |
| 10 | Enhancing Li NiO_(2) cathode materials by concentration-gradient yttrium modification for rechargeable lithium-ion batteries显示文摘Lithium nickel oxide(LiNiO_(2)) cathode materials are featured with high capacity and low cost for rechargeable lithium-ion batteries but suffer from severe interface and structure instability.Here we report that rationally designed LiNiO_(2) via concentration-gradient yttrium modification exhibits alleviative side reactions and improved electrochemical performance.The LiNiO_(2) cathode with LiYO_(2)-Y_(2) O_(3) coating layer delivers a discharge capacity of 225 mAh g^(-1) with a high initial Coulombic efficiency of 93.4%.These improvements can be attributed to the formation of in-situ modified hybrid LiYO_(2)-Y_(2 O3) coating layer,which suppresses phase transformation,electrolyte oxidation and salt dissociation due to the formation of protective cathode electrolyte interface.The results indicate promising application of concentration-gradient yttrium coating as a facile approach to stabilize nickel-rich cathode materials. | Yudong Zhang Hang Li Junxiang Liu Jiuding Liu Hua Ma Fangyi Cheng | 2021 | Journal of Energy Chemistry2021,30,12: | 2 |
| 11 | Cell-nucleus structured electrolyte for low-temperature aqueous zinc batteries显示文摘Rechargeable aqueous zinc(Zn) batteries hold great promise for large-scale energy storage,but their implementation is plagued by poor Zn reversibility and unsatisfactory low-temperature performance.Herein,we design a cell-nucleus structured electrolyte by introducing low-polarity 1,2-dimethoxyethane(DME) into dilute 1 M zinc trifluoromethanesulfonate(Zn(OTf)_(2)) aqueous solution,which features an OTf--rich Zn2^(+)-primary solvation sheath(PSS,inner nucleus) and the DMEmodulated Zn^(2+)-outer solvation sheath(outer layer).We find that DME additives with a low dosage do not participate in the Zn2+-PSS but reinforce the Zn-OTf-coordination,which guarantees good reaction kinetics under ultralow temperatures.Moreover,DME breaks the original H-bonding network of H2O,depressing the freezing point of electrolyte to-52.4℃.Such a cell-nucleus-solvation structure suppresses the H_(2)O-induced side reactions and forms an anion-derived solid electrolyte interphase on Zn and can be readily extended to 1,2-diethoxyethane.The as-designed electrolyte enables the Zn electrode deep cycling stability over 3500 h with a high depth-of-discharge of 51.3% and endows the Zn‖V_(2)O_(5)full battery with stable cycling over 1000 cycles at 40℃.This work would inspire the solvation structure design for low-temperature aqueous batteries. | Yang Dong Ning Zhang Zhaodong Wang Jinhan Li Youxuan Ni Honglu Hu Fangyi Cheng | 2023 | Journal of Energy Chemistry2023,,8: | 2 |
| 12 | Electrodeposition of Pt-Decorated Ni(OH)_(2)/CeO_(2) Hybrid as Superior Bifunctional Electrocatalyst for Water Splitting显示文摘The facile synthesis of highly active and stable bifunctional electrocatalysts to catalyze water splitting is attractive but challenging.Herein,we report the electrodeposition of Pt-decorated Ni(OH)_(2)/CeO_(2)(PNC)hybrid as an efficient and robust bifunctional electrocatalyst.The graphite-supported PNC catalyst delivers superior hydrogen evolution reaction(HER)and oxygen evolution reaction(OER)activities over the benchmark Pt/C and RuO_(2),respectively.For overall water electrolysis,the PNC hybrid only requires a cell voltage of 1.45V at 10mAcm-2 and sustains over 85 h at 1000mAcm^(-2).The remarkable HER/OER performances are attributed to the superhydrophilicity and multiple effects of PNC,in which Ni(OH)_(2)and CeO_(2)accelerate HER on Pt due to promoted water dissociation and strong electronic interaction,while the electron-pulling Ce cations facilitate the generation of high-valence Ni OER-active species.These results suggest the promising application of PNC for H2 production from water electrolysis. | Huanhuan Liu Zhenhua Yan Xiang Chen Jinhan Li Le Zhang Fangming Liu Guilan Fan Fangyi Cheng | 2020 | Research2020,,1: | 2 |
| 13 | Nomogram based on albumin-bilirubin grade to predict outcome of the patients with hepatitis C virus-related hepatocellular carcinoma after microwave ablation显示文摘Objective:To construct a nomogram based on the albumin-bilirubin(ALBI)grade to provide prognostic value for hepatitis C virus(HCV)-related hepatocellular carcinoma(HCC)patients who underwent ultrasound-guided percutaneous microwave ablation(US-PMWA).Methods:From April 2005 to January 2018,183 treatment-naIve patients with 251 HCV-related HCCs according to the Milan criteria received US-PMWA subsequently.The overall survival(OS)and recurrence-free survival(RFS)were compared between groups classified by ALBI grade.Cox proportional hazard regression model based on risk factors for survival and recurrence was used to construct the nomogram.Results:The cumulative OS rates at 1-,3-,5-and 10-year were 97.7%,73.6%,54.5%and 34.5%,respectively.Stratified according to ALBI grade,the 1-,3-,and 5-year OS in the ALBI grade 1 group and grade 2 group were 99.2%,92.4%,77.9% and 97.7%,52.3%,38.6%,respectively,with significant statistical difference(P<0.001).No significant statistical difference was detected in the1-,3-,and 5-year RFS rates in the ALBI grade 1 group and grade 2 group(P=0.220).The major complication rate was 1.6%.Multivariate analysis results showed age,α-fetoprotein level,tumor number,platelet count,location,Child-Turcotte-Pugh(CTP)and ALBI grade were associated with OS,which generated the nomograms.Internal validation with 1000 bootstrapped sample sets had good concordance index of 0.769(95%CI 0.699-0.839)in OS.Conclusions:This nomogram based on ALBI grade was a visualization risk model,which could provide personalized prediction of long-term outcomes for HCV-related HCC patients after US-PMWA. | Chao An Xin Li Xiaoling Yu Zhigang Cheng Zhiyu Han Fangyi Liu Jie Yu Ping Liang | 2019 | Cancer Biology & Medicine2019,16,4: | 2 |
