| 1 | Effect of different concentrations of surfactant on the wettability of coal by molecular dynamics simulation显示文摘Anionic surfactant sodium dodecyl benzene sulfonate(SDBS)at varying concentrations was selected to investigate the influence on the wettability of Zhaozhuang Coal by molecular dynamics simulation.Six groups of water/surfactant/coal systems with different concentrations were constructed.The influence of surfactant with different concentrations on the wettability of coal was concluded by analyzing various properties from the energetic behaviors to the dynamic characteristics.The results show that the interfacial tension decreases sharply and then rises slowly with the increase of SDBS surfactant concentration,obtaining that surfactants can obviously reduce the interfacial tension.The surfactant molecules could be detected at the water/coal interface through analyzing the system’s relative concentration distribution.In addition,the difference in the wettability of surfactants on coal surfaces is caused by the spatial distribution differences of alkyl chains and the benzene ring of the surfactant molecules.And the negative interaction energy between SDBS and the coal surface indicates that adsorption process is spontaneous.Furthermore,it is of great practical significance for improving the dust reduction effect and reducing the disaster of coal dust by exploring the effects of surfactant molecules on the wettability of coal. | Junqing Meng Feifei Yin Shichao Li Ruquan Zhong Zeyuan Sheng Baisheng Nie | 2019 | International Journal of Mining Science and Technology2019，29，4： | 20 |
| 2 | Ferroptosis as a novel form of regulated cell death:Implications in the pathogenesis,oncometabolism and treatment of human cancer显示文摘The treatment of cancer mainly involves surgical excision supplemented by radiotherapy and chemotherapy.Chemotherapy drugs act by interfering with tumor growth and inducing the death of cancer cells.Anti-tumor drugs were developed to induce apoptosis,but some patient’s show apoptosis escape and chemotherapy resistance.Therefore,other forms of cell death that can overcome the resistance of tumor cells are important in the context of cancer treatment.Ferroptosis is a newly discovered iron-dependent,non-apoptotic type of cell death that is highly negatively correlated with cancer development.Ferroptosis is mainly caused by the abnormal increase in iron-dependent lipid reactive oxygen species and the imbalance of redox homeostasis.This review summarizes the progression and regulatory mechanism of ferroptosis in cancer and discusses its possible clinical applications in cancer diagnosis and treatment. | Feifei Pu Fengxia Chen Zhicai Zhang Deyao Shi Binlong Zhong Xiao Lv Andrew Blake Tucker Jiaming Fan Alexander J.Li Kevin Qin Daniel Hu Connie Chen Hao Wang Fang He Na Ni Linjuan Huang Qing Liu William Wagstaff Hue H.Luu Rex C.Haydon Le Shen Tong-Chuan He Jianxiang Liu Zengwu Shao | 2022 | Genes & Diseases2022，9，2： | 6 |
| 3 | Transition prediction and sensitivity analysis for a natural laminar flow wing glove flight experiment显示文摘Natural laminar flow technology can significantly reduce aircraft aerodynamic drag and has excellent technical appeal for transport aircraft development with high aerodynamic efficiency.Accurately and efficiently predicting the laminar-to-turbulent transition and revealing the maintenance mechanism of laminar flow in a transport aircraft’s flight environment are significant for developing natural laminar flow wings.In this research,we carry out natural laminar flow flight experiments with different Reynolds numbers and angles of attack.The critical N-factor is calibrated as 9.0 using flight experimental data and linear stability theory from a statistical perspective,which makes sure that the relative error of transition location is within 5%.We then implement a simplified e^(N) transition prediction method with a similar accuracy compared with linear stability theory.We compute the sensitivity information for the simplified eN method with an adjointbased method,using the automatic differentiation technique(ADjoint).The impact of Reynolds numbers and pressure distributions on TS waves is analyzed using the sensitivity information.Through the sensitivity analysis,we find that:favorable pressure gradients not only suppress the development of TS waves but also decrease their sensitivity to Reynolds numbers;there exist three special regions which are very sensitive to the pressure distribution,and the sensitivity decreases as the local favorable pressure gradient increases.The proposed sensitivity analysis method enables robust natural laminar flow wings design. | Tihao YANG Hai ZHONG Yifu CHEN Yayun SHI Junqiang BAI Feifei QIN | 2021 | Chinese Journal of Aeronautics2021，34，8： | 5 |
| 4 | Trust-Based Context-Aware Mobile Social Network Service Recommendation显示文摘The service recommendation mechanism as a key enabling technology that provides users with more proactive and personalized service is one of the important research topics in mobile social network(MSN). Meanwhile,MSN is susceptible to various types of anonymous information or hacker actions. Trust can reduce the risk of interaction with unknown entities and prevent malicious attacks. In our paper,we present a trust-based service recommendation algorithm in MSN that considers users' similarity and friends' familiarity when computing trustworthy neighbors of target users. Firstly,we use the context information and the number of co-rated items to define users' similarity. Then,motivated by the theory of six degrees of space,the friend familiarity is derived by graph-based method. Thus the proposed methods are further enhanced by considering users' context in the recommendation phase. Finally,a set of simulations are conducted to evaluate the accuracy of the algorithm. The results show that the friend familiarity and user similarity can effectively improve the recommendation performance,and the friend familiarity contributes more than the user similarity. | XU Jun ZHONG Yuansheng ZHU Wenqiang SUN Feifei | 2017 | Wuhan University Journal of Natural Sciences2017，22，2： | 4 |
| 5 | Growth of Anisotropic Platinum Nanostructures Catalyzed by Gold Seed Nanoparticles显示文摘This paper reports an effective method for the synthesis of platinum nanostructures with anisotropic morphologies by decomposition of platinum dichloride in oleylamine at intermediate temperatures catalyzed by gold seed nanoparticles.A small quantity of spherical gold nanoparticles formed in situ was used to trigger the nucleation and anisotropic growth of the Pt nanocrystals.By varying the amount of gold seed nanoparticles,porous fl ower-like,irregular polyhedron-shaped,multi-branched rod shaped,and caterpillar-like Pt nanostructures were produced in high yields at 190240°C in reaction times of a few minutes.Control of morphology under different conditions has been systematically studied and a kinetically controlled induced growth mechanism has been proposed. | Zheng Fang Yuliang Zhang Feifei Du Xinhua Zhong | 2008 | Nano Research2008，1，3： | 3 |
| 6 | Cochlear implantation outcomes in children with common cavity deformity;a retrospective study显示文摘Objective: A common cavity deformity(CCD) is a deformed inner ear in which the cochlea and vestibule are confluent forming a common rudimentary cystic cavity that results in profound hearing loss. There are few studies paying attention to common cavity. Our group is engrossed in observing the improvement of auditory and verbal abilities in children who have received cochlear implantation(CI), and comparing these targets between children with common cavity and normal inner ear structure.Material and methods: A retrospective study was conducted in 12 patients with profound hearing loss that were divided into a common cavity group and a control group, six in each group matched in sex, age and time of implantation, based on inner ear structure. Categories of Auditory Performance(CAP) and speech intelligibility rating(SIR) scores and aided hearing thresholds were collected and compared between the two groups. All patients wore CI for more than 1 year at the Cochlear Center of Anhui Medical University from 2011 to 2015.Results: Postoperative CAP and SIR scores were higher than before operation in both groups(p < 0.05), although the scores were lower in the CCD group than in the control group(p < 0.05). The aided threshold was also lower in the control group than in the CCD group(p < 0.05).Conclusion: Even though audiological improvement in children with CCD was not as good as in those without CCD, CI provides benefits in auditory perception and communication skills in these children. | Li Zhang Jianxin Qiu Feifei Qin Mei Zhong Gyanendra Shah | 2017 | Journal of Otology2017，12，3： | 3 |
| 7 | Data-Driven Discovery in Mineralogy: Recent Advances in Data Resources, Analysis, and Visualization显示文摘Large and growing data resources on the diversity, distribution, and properties of minerals are ushering in a new era of data-driven discovery in mineralogy. The most comprehensive international mineral database is the IMA database, which includes information on more than 5400 approved mineral species and their properties, and the mindat.org data source, which contains more than 1 million species/locality data on minerals found at more than 300 000 localities. Analysis and visualization of these data with diverse techniques—including chord diagrams, cluster diagrams, Klee diagrams, skyline diagrams, and varied methods of network analysis—are leading to a greater understanding of the co-evolving geosphere and biosphere. New data-driven approaches include mineral evolution, mineral ecology, and mineral network analysis—methods that collectively consider the distribution and diversity of minerals through space and time. These strategies are fostering a deeper understanding of mineral co-occurrences and, for the first time, facilitating predictions of mineral species that occur on Earth but have yet to be discovered and described. | Robert M.

| 8 | Enhanced treatment for cerebral ischemia-reperfusion injury of puerarin loading liposomes through neutrophils-mediated targeted delivery显示文摘The recovery of blood circulation following cerebral infarction-associated thrombolysis brings new damage to the brain,which is cerebral ischemia-reperfusion injury(CIRI).Inflammation is the main pathological mechanism of CIRI.The inflammatory response triggered by cerebral ischemia-reperfusion provides neutrophils with a special opportunity to facilitate drug delivery to the site of ischemic penumbra through the chemotaxis of inflammatory factors by neutrophils.Puerarin is an isoflavone derivative with a significant neuroprotective effect in vitro.But the blood-brain barrier(BBB)impedes its therapeutic efficacy on CIRI within the brain.Inspired by the pathological process,we have used neutrophils as carriers to enhance the BBB penetration of liposomes loaded with puerarin and improve the concentration of puerarin in the brain parenchyma in this study.These results showed that puerarin-containing liposomes were released in response to inflammatory conditions associated with brain injury to enhance the neuroprotection effect at the ischemic penumbra. | Wei Liu Haowei Lu Xiaoyong Rao Xiang Li Hongdan Lu Feifei Li Yan He Riyue Yu Rongsheng Zhong Yao Zhang Xiaojian Luo Hongliang Xin | 2021 | Nano Research2021，14，12： | 2 |

| 12 | A stability locomotion-control strategy for quadruped robots with center-of-mass dynamic planning显示文摘Locomotion stability is essential for controlling quadruped robots and adapting them to unstructured terrain.We propose a control strategy with center-of-mass(CoM)dynamic planning for the stable locomotion of these robots.The motion trajectories of the swing legs are synchronized with the CoM of the robot.To implement the synchronous control scheme,we adjusted the swing legs to form a support triangle.The strategy is applicable to both static walk gait and dynamic trot gait.In the motion control processes of the robot legs,the distribution of the ground reaction forces is optimized to minimize joint torque and locomotion energy consumption.We also used an improved joint-torque controller with varied controller coefficients in the stance and swing phases.The simulation and experimental results demonstrate that the robot can complete omnidirectional locomotion in both walk and trot gaits.At a given locomotion speed,the stability margins for the robot during walking and trotting were 27.25%and 37.25%higher,respectively,than in the scheme without CoM planning.The control strategy with energy consumption optimization(ECO)reduced the energy consumption of the robot in walk and trot gaits by 11.25%and 13.83%,respectively,from those of the control scheme without ECO. | Yangyang HAN Guoping LIU Zhenyu LU Huaizhi ZONG Junhui ZHANG Feifei ZHONG Liyu GAO | 2023 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2023，24，6： | 0 |
| 13 | Tuning the charge distribution and crystal field of iron single atoms via iron oxide integration for enhanced oxygen reduction reaction in zinc-air batteries显示文摘Metal-air batteries face a great challenge in developing efficient and durable low-cost oxygen reduction reaction(ORR)electrocatalysts.Single-atom iron catalysts embedded into nitrogen doped carbon(Fe-N-C)have emerged as attractive materials for potential replacement of Pt in ORR,but their catalytic performance was limited by the symmetrical electronic structure distribution around the single-atom Fe site.Here,we report our findings in significantly enhancing the ORR performance of Fe-N-C by moderate Fe_(2)O_(3) integration via the strong electronic interaction.Remarkably,the optimized catalyst(M-Fe_(2)O_(3)/Fe_(SA)@NC)exhibits excellent activity,durability and good tolerance to methanol,outperforming the benchmark Pt/C catalyst.When M-Fe_(2)O_(3)/Fe_(SA)@NC catalyst was used in a practical zinc-air battery assembly,peak power density of 155 mW cm^(-2)and specific capacity of 762 mA h g_(Zn)^(-1)were achieved and the battery assembly has shown superior cycling stability over a period of 200 h.More importantly,theoretical studies suggest that the introduction of Fe_(2)O_(3) can evoke the crystal field alteration and electron redistribution on single Fe atoms,which can break the symmetric charge distribution of Fe-N_(4) and thereby optimize the corresponding adsorption energy of intermediates to promote the O_(2)reduction.This study provides a new pathway to promote the catalytic performance of single-atom catalysts. | Feifei Zhang Yinlong Zhu Yijun Zhong Jing Zou Yu Chen Lianhai Zu Zhouyou Wang Jack Jon Hinsch Yun Wang Lian Zhang Zongping Shao Huanting Wang | 2023 | Journal of Energy Chemistry2023，，10： | 0 |
| 14 | Two‑Dimensional Mesoporous Materials for Energy Storage and Conversion:Current Status,Chemical Synthesis and Challenging Perspectives显示文摘Two-dimensional(2D)mesoporous materials(2DMMs),defined as 2D nanosheets with randomly dispersed or orderly aligned mesopores of 2–50 nm,can synergistically combine the fascinating merits of 2D materials and mesoporous mate-rials,while overcoming their intrinsic shortcomings,e.g.,easy self-stacking of 2D materials and long ion transport paths in bulk mesoporous materials.These unique features enable fast ion diffusion,large specific surface area,and enriched adsorption/reaction sites,thus offering a promising solution for designing high-performance electrode/catalyst materials for next-generation energy storage and conversion devices(ESCDs).Herein,we review recent advances of state-of-the-art 2DMMs for high-efficiency ESCDs,focusing on two different configurations of in-plane mesoporous nanosheets and sandwich-like mesoporous heterostructures.Firstly,a brief introduction is given to highlighting the structural advantages(e.g.,tailored chemical composition,sheet configuration,and mesopore geometry)and key roles(e.g.,active materials and functional additives)of 2DMMs for high-performance ESCDs.Secondly,the chemical synthesis strategies of 2DMMs are summarized,including template-free,2D-template,mesopore-template,and 2D mesopore dual-template methods.Thirdly,the wide applications of 2DMMs in advanced supercapacitors,rechargeable batteries,and electrocatalysis are discussed,enlightening their intrinsic structure–property relationships.Finally,the future challenges and perspectives of 2DMMs in energy-related fields are presented. | Jieqiong Qin Zhi Yang Feifei Xing Liangzhu Zhang Hongtao Zhang Zhong‑Shuai Wu | 2023 | Electrochemical Energy Reviews2023，6，1： | 0 |
| 15 | Contact detection with multi-information fusion for quadruped robot locomotion under unstructured terrain显示文摘Reliable foot-to-ground contact state detection is crucial for the locomotion control of quadruped robots in unstructured environments.To improve the reliability and accuracy of contact detection for quadruped robots,a detection approach based on the probabilistic contact model with multi-information fusion is presented to detect the actual contact states of robotic feet with the ground.Moreover,a relevant control strategy to address unexpected early and delayed contacts is planned.The approach combines the internal state information of the robot with the measurements from external sensors mounted on the legs and feet of the prototype.The overall contact states are obtained by the classification of the model-based predicted probabilities.The control strategy for unexpected foot-to-ground contacts can correct the control actions of each leg of the robot to traverse cluttered environments by changing the contact state.The probabilistic model parameters are determined by testing on the single-leg experimental platform.The experiments are conducted on the experimental prototype,and results validate the contact detection and control strategy for unexpected contacts in unstructured terrains during walking and trotting.Compared with the body orientation under the time-based control method regardless of terrain,the root mean square errors of roll,pitch,and yaw respectively decreased by 60.07%,54.73%,and 64.50%during walking and 73.40%,61.49%,and 61.48%during trotting. | Yangyang HAN Zhenyu LU Guoping LIU Huaizhi ZONG Feifei ZHONG Shengyun ZHOU Zekang CHEN | 2023 | Frontiers of Mechanical Engineering2023，18，3： | 0 |
| 16 | Serum procalcitonin levels are associated with rhabdomyolysis following exertional heatstroke: an over 10-year intensive care survey显示文摘BACKGROUND:Heatstroke has become a common emergency event in hospitals.Procalcitonin(PCT)is used as a biomarker of infection in the emergency department(ED),but its role in rhabdomyolysis(RM)following exertional heatstroke(EHS)remains unclear.METHODS:A retrospective cohort study enrolled patients with EHS from the intensive care unit(ICU).We collected RM biomarkers,inflammation markers,critical disease scores at admission,24 h,48 h,and discharge,and 90-day mortality.Correlation analysis,linear regression and curve fi tting were used to identify the relationship between PCT and RM.RESULTS:A total of 162 patients were recruited and divided into RM(n=56)and non-RM(n=106)groups.PCT was positively correlated with myoglobin(Mb),acute hepatic injury,disseminated intravascular coagulation(DIC),Sequential Organ Failure Assessment(SOFA)score,and Acute Physiology and Chronic Health Evaluation II(APACHE II)score,with correlation coefficients of 0.214,0.237,0.285,0.454,and 0.368,respectively(all P<0.05).Interestingly,the results of curve fi tting revealed a nonlinear relationship between PCT and RM,and a two-piecewise linear regression model showed that PCT was related to RM with an odds ratio of 1.3 and a cut-off of<4.6 ng/mL.Survival analysis revealed that RM was associated with higher mortality compared to non-RM cases(P=0.0093).CONCLUSION:High serum PCT concentrations are associated with RM after EHS in critically ill patients.Elevated PCT concentrations should be interpreted cautiously in patients with EHS in the ED. | Li Zhong Feifei Shuai Conglin Wang Lipeng Han Zhifeng Liu Ming Wu | 2024 | World Journal of Emergency Medicine2024，15，1： | 0 |
| 17 | Identifying a confused cell identity for esophageal squamous cell carcinoma显示文摘The cell identity of malignant cells and how they acquire it are fundamental for our understanding of cancer.Here,we report that esophageal squamous cell carcinoma(ESCC)cells display molecular features equally similar but distinct to all three types of normal esophageal epithelial cells,which we term as confused cell identity(CCI).CCI is an independent prognostic marker associated with poor prognosis in ESCC.Further,we identify tropomyosin 4(TPM4)as a critical CCI gene that promotes the aggressiveness of ESCC in vitro and in vivo.And TPM4 creates CCI through activating the Jak/STAT-SOX2 pathway.Thus,our study suggests an unrecognized feature of ESCC cells,which might be of value for clinic prognosis and potential interference. | Xiangyu Pan Jian Wang Linjie Guo Feifei Na Jiajia Du Xuelan Chen Ailing Zhong Lei Zhao Lu Zhang Mengsha Zhang Xudong Wan Manli Wang Hongyu Liu Siqi Dai Ping Tan Jingyao Chen Yu Liu Bing Hu Chong Chen | 2022 | Signal Transduction and Targeted Therapy2022，7，5： | 0 |
| 18 | Hierarchically Structured Nb_(2)O_5 Microflowers with Enhanced Capacity and Fast-Charging Capability for Flexible Planar Sodium Ion Micro-Supercapacitors显示文摘Planar Na ion micro-supercapacitors(NIMSCs) that offer both high energy density and power density are deemed to a promising class of miniaturized power sources for wearable and portable microelectron-ics. Nevertheless, the development of NIMSCs are hugely impeded by the low capacity and sluggish Na ion kinetics in the negative electrode.Herein, we demonstrate a novel carbon-coated Nb_(2)O_5 microflower with a hierarchical structure composed of vertically intercrossed and porous nanosheets, boosting Na ion storage performance. The unique structural merits, including uniform carbon coating, ultrathin nanosheets and abun-dant pores, endow the Nb_(2)O_5 microflower with highly reversible Na ion storage capacity of 245 mAh g^(-1) at 0.25 C and excellent rate capability.Benefiting from high capacity and fast charging of Nb_(2)O_5 microflower, the planar NIMSCs consisted of Nb_(2)O_5 negative electrode and activated car-bon positive electrode deliver high areal energy density of 60.7 μWh cm^(-2),considerable voltage window of 3.5 V and extraordinary cyclability. Therefore, this work exploits a structural design strategy towards electrode materials for application in NIMSCs, holding great promise for flexible microelectronics. | Jiaxin Ma Jieqiong Qin Shuanghao Zheng Yinghua Fu Liping Chi Yaguang Li Cong Dong Bin Li Feifei Xing Haodong Shi Zhong‑Shuai Wu | 2024 | Nano-Micro Letters2024，16，4： | 0 |
