| 1 | Niobium Tungsten Oxide in a Green Water‑in‑Salt Electrolyte Enables Ultra‑Stable Aqueous Lithium‑Ion Capacitors显示文摘Aqueous hybrid supercapacitors are attracting increasing attention due to their potential low cost,high safety and eco-friendliness.However,the narrow operating potential window of aqueous electrolyte and the lack of suitable negative electrode materials seriously hinder its future applications.Here,we explore high concentrated lithium acetate with high ionic conductivity of 65.5 mS cm−1 as a green“water-in-salt”electrolyte,providing wide voltage window up to 2.8 V.It facilitates the reversible function of niobium tungsten oxide,Nb18W16O93,that otherwise only operations in organic electrolytes previously.The Nb18W16O93 with lithium-ion intercalation pseudocapacitive behavior exhibits excellent rate performance,high areal capacity,and ultra-long cycling stability.An aqueous lithium-ion hybrid capacitor is developed by using Nb18W16O93 as negative electrode combined with graphene as positive electrode in lithium acetate-based“water-in-salt”electrolyte,delivering a high energy density of 41.9 W kg−1,high power density of 20,000 W kg−1 and unexceptionable stability of 50,000 cycles. | Shengyang Dong Yi Wang Chenglong Chen Laifa Shen Xiaogang Zhang | 2020 | Nano-Micro Letters2020，12，12： | 4 |
| 2 | RAISING STUDENT'S AWARENESS ABOUT WRITING IN ENGLISH显示文摘In recent years, although college students have acquired ahigh level of proficiency in English reading, they have made verylittle advancement in English writing. This is due to the factthat inadequate importance is attached to writing in the teachingof English, and that students have rather vague ideas about therole of writing in foreign language learning and about the differ-ent discourse patterns existing between English and Chinese.Thus, this paper suggests that, in order to improve students’writing ability, two ways be adopted to raise students’ awarenessof learning to write: 1) integrating the product-oriented ap-proach with the process-oriented approach; 2) using students’reading as a writing source. | Li Xiaohong Li Laifa Harbin Institute of Technology | 2001 | Chinese Journal of Applied Linguistics2001，24，1： | 4 |
| 3 | Spatial Evolution Study of EEDFs and Plasma Parameters in RF Stochastic Regime by Langmuir Probe显示文摘An RF compensated cylindrical Langmuir probe system has been developed and used to characterize an RF capacitive two temperature plasma discharge in a stochastic mode.The novelty of the work presented here is the use of the driven electrode(cathode)without ground shield.Measurements of the electron energy distribution function(EEDF)and plasma parameters were achieved under the following conditions:50 W of RF power and 5×10-2mbar of argon pressure.The probe measurements are performed at 3 cm above the electrode and the probe was shifted radially(r direction)from the center(r=0 cm)of the inter-electrodes region towards the chamber wall(R=10.75 cm).The results show that the EEDF is bi-Maxwellian and its shape remains the same through the scanned region.The farther the probe from the central region,the lower the EEDF maximum.The plasma density is observed to decrease according to a Gaussian profile along the radial direction and falls to 50%of its maximum when close to the cathode edge(r=5.5 cm).At the same time the effective electron temperature remains constant for r<4 cm and increases for r≥4 cm.The high-temperature and low-temperature electrons’densities and temperatures are also discussed in the article. | Djelloul MENDIL Hadj LAHMAR Laifa BOUFENDI | 2014 | Plasma Science and Technology2014，16，9： | 3 |

| 6 | Electrochemical Proton Storage:From Fundamental Understanding to Materials to Devices显示文摘Simultaneously improving the energy density and power density of electrochemical energy storage systems is the ultimate goal of electrochemical energy storage technology.An effective strategy to achieve this goal is to take advantage of the high capacity and rapid kinetics of electrochemical proton storage to break through the power limit of batteries and the energy limit of capacitors.This article aims to review the research progress on the physicochemical properties,electrochemical performance,and reaction mechanisms of electrode materials for electrochemical proton storage.According to the different charge storage mechanisms,the surface redox,intercalation,and conversion materials are classified and introduced in detail,where the influence of crystal water and other nanostructures on the migration kinetics of protons is clarified.Several reported advanced full cell devices are summarized to promote the commercialization of electrochemical proton storage.Finally,this review provides a framework for research directions of charge storage mechanism,basic principles of material structure design,construction strategies of full cell device,and goals of practical application for electrochemical proton storage. | Tiezhu Xu Di Wang Zhiwei Li Ziyang Chen Jinhui Zhang Tingsong Hu Xiaogang Zhang Laifa Shen | 2022 | Nano-Micro Letters2022，14，8： | 1 |

| 17 | Template-Free Synthesis of Ordered Mesoporous NiO/Poly (Sodium-4-Styrene Sulfonate) Functionalized Carbon Nanotubes Composite for Electrochemical Capacitors显示文摘We report the first example of a practical and efficient template-free strategy for synthesizing ordered mesoporous NiO/poly(sodium-4-styrene sulfonate)(PSS)functionalized carbon nanotubes(FCNTs)composites by calcining a Ni(OH)_(2)/FCNTs precursor prepared by refl uxing an alkaline solution of Ni(NH_(3))x^(2)+and FCNTs at 97 oC for 1 h.The morphology and structure were characterized by X-ray diffraction,scanning electron microscopy,and transmission electron microscopy.Thermal decomposition of the precursor results in the formation of ordered mesoporous NiO/FCNTs composite(ca.48 wt%NiO)with large specifi c surface area.Due to its enhanced electronic conductivity and hierarchical(meso-and macro-)porosity,composite simultaneously meets the three requirements for energy storage in electrochemical capacitors at high rate,namely,good electron conductivity,highly accessibleelectrochemical surface areas owing to the existence of mesopores,and efficient mass transport from the macropores.Electrochemical data demonstrated that the ordered mesoporous NiO/FCNTs composite is capable of delivering a specifi c capacitance(SC)of 526 F/g at 1 A/g and a SC of 439 F/g even at 6 A/g,and show a degradation of only ca.6%in SC after 2000 continuous charge/discharge cycles. | Changzhou Yuan Shenglin Xiong Xiaogang Zhang Laifa Shen Fang Zhang Bao Gao Linhao Su | 2009 | Nano Research2009，2，9： | 1 |
