| 1 | Development of Cementitious Materials Utilizing Alkali-activated Yellow River Silt显示文摘The possibility of preparing cementitious materials by the alkali-activated method using Yellow River sediment(The second largest river in China)as raw material and the modification effect on different slag addition were investigated.Sodium silicate and calcium hydroxide were used as the activator,and the specimens were prepared by the press molding method.The hydration process,hydration products,pore characteristics,and mechanical properties were investigated using SEM/EDS,FTIR,TG/DTG,XRD,MIP,and uniaxial compressive strength experiments,respectively.The results showed that the compressive strength of the modified yellow river silt-based cementitious material was significantly increased when the water glass dosage was 12 wt%(Ms=1.8)and the slag dosage was 40%,and its 90-day maximum compressive strength could reach 53 MPa. | 王宝民 WANG Wanli 梁晓霞 刘慧 HAN Junnan ZHAO Lu YANG Xingxing YAN Jifei | 2021 | Journal of Wuhan University of Technology(Materials Science)2021，36，3： | 5 |
| 2 | Bloodletting at Jing-well points decreases interstitial fluid flow in the thalamus of rats显示文摘OBJECTIVE: To investigate the changes in the neuronal microenvironment of the middle cerebral artery(MCA) territory induced by Jing-well points bloodletting acupuncture(WPBA) and to explore the neuroprotective mechanism of WPBA in stroke.METHODS: Adult male Sprague Dawley(n = 32)rats were randomly divided into four groups of eight animals each: WPBA-thalamus group(WT),WPBA-caudate nucleus group(WC), sham-control thalamus group(ST) and sham-control caudate nucleus group(SC). Animals in the WT and WC groups received 2 μL of the extracellular tracer gadolinium-diethylene triamine pentaacetic acid(Gd-DTPA)injected into the thalamus or caudate nucleus, respectively, and 12 Jing-well points in the distal ends of the rats' digits were used for WPBA. Although 2 μL of Gd-DTPA was injected into the thalamus or caudate nucleus, respectively, for animals in the two sham groups(ST and SC), no acupuncture or bloodletting was performed. Brain extracellular space and interstitial fluid flow parameters were measured using Gd-DTPA-enhanced magnetic resonance imaging.RESULTS: The brain interstitial fluid flow speed was decreased in the thalamus after WPBA, with a significantly lower Gd-DTPA clearance rate and longer half-life of Gd-DTPA in the thalamus of treated rats than those in sham-control rats [WPBA-treated rats' clearance rate,(7.47 ± 3.15) × 10^(-5)/s(P = 0.009);half-life,(1.52 ± 0.13) h, P = 0.000]. By contrast, no significant changes in brain extracellular space and interstitial fluid flow parameters were detected in the caudate nucleus after WPBA(P = 0.649). In addition, no differences in the morphology of the brain extracellular space or the final distribution of the traced brain interstitial fluid were demonstrated between the WT and WC groups(P = 0.631, P = 0.970,respectively).CONCLUSION: The WPBA decreased the speed of the local thalamic ISF flow in rats, which is assumed to be a beneficial protection by down-modulated the metabolic rate of the attacked neurons under stroke. | FuYu LiYuliang GuoJia Liu Bin Liu Huipo Zhang Weibo Sun Wanli GaoYajuan Ren Qiushi Han Haojun | 2016 | Journal of Traditional Chinese Medicine2016，36，1： | 3 |

| 6 | Unraveling Passivation Mechanism of Imidazolium-Based Ionic Liquids on Inorganic Perovskite to Achieve Near-Record-Efficiency CsPbI_(2)Br Solar Cells显示文摘The application of ionic liquids in perovskite has attracted wide-spread attention for its astounding performance improvement of perovskite solar cells(PSCs).However,the detailed mechanisms behind the improvement remain mysterious.Herein,a series of imidazolium-based ionic liquids(IILs)with different cations and anions is systematically investigated to elucidate the passivation mechanism of IILs on inorganic perovskites.It is found that IILs display the following advantages:(1)They form ionic bonds with Cs^(+)and Pb^(2+)cations on the surface and at the grain boundaries of perovskite films,which could effectively heal/reduce the Cs^(+)/I−vacancies and Pb-related defects;(2)They serve as a bridge between the perovskite and the hole-transport-layer for effective charge extraction and transfer;and(3)They increase the hydrophobicity of the perovskite surface to further improve the stability of the CsPbI_(2)Br PSCs.The combination of the above effects results in suppressed non-radiative recombination loss in CsPbI_(2)Br PSCs and an impressive power conversion efficiency of 17.02%.Additionally,the CsPbI_(2)Br PSCs with IILs surface modification exhibited improved ambient and light illumination stability.Our results provide guidance for an indepth understanding of the passivation mechanism of IILs in inorganic perovskites. | Jie Xu Jian Cui Shaomin Yang Yu Han Xi Guo Yuhang Che Dongfang Xu Chenyang Duan Wenjing Zhao Kunpeng Guo Wanli Ma Baomin Xu Jianxi Yao Zhike Liu Shengzhong Liu | 2022 | Nano-Micro Letters2022，14，1： | 1 |

| 10 | Developing in situ electron paramagnetic resonance characterization for understanding electron transfer of rechargeable batteries显示文摘Electrochemical energy storage devices are pivotal in achieving“carbon neutrality”by enabling the storage of energy generated from renewable sources.To facilitate the development of these devices,it is important to gain insight into the underlying the single-/multi-electron transfer process.This can be achieved through in-time detection under operational conditions,but there are limited tools available for monitoring electron transfer under operando conditions.Electron paramagnetic resonance(EPR)is a powerful technique that can meet these expectations,as it is highly sensitive to unpaired electrons and can detect changes of paramagnetic centres.Despite the long history of in situ electrochemical EPR research,its potential has been surprisingly underutilized due to the need for strict operando cell design under special testing conditions.This review comprehensively summarizes recent efforts to understand energy storage mechanisms using in situ/operando EPR,with the aim of drawing researchers’attention to this powerful technique.After introducing the fundamental principles of EPR,we describe the critical advances made in detecting batteries using operando EPR,along with the remaining challenges and opportunities for future development of this technology in batteries.We emphasize the need for strict operando cell design and the importance of designing experiments that closely mimic real-world conditions.We believe that this review will provide innovative solutions to solve tough problems that researchers may encounter during their battery research,and ultimately contribute to the development of more efficient and sustainable energy storage devices. | Bin Wang Wanli Wang Kang Sun Yujie Xu Yi Sun Qiang Li Han Hu Mingbo Wu | 2023 | Nano Research2023，16，10： | 1 |
| 11 | In Situ Synthesis of Cuprous Oxide/Cellulose Nanofibers Gel and Antibacterial Properties显示文摘Cellulose nanofibers were synthesized by acetobacter xylinum(xylinum 1.1812).The cellulose nanofibers with 30-90 nm width constructed three-dimension network gel,which could be used as a wound dressing since it can provide moist environment to a wound.However,cellulose nanofibers have no antimicrobial activity to prevent wound infection.To achieve antimicrobial activity,the cellulose nanofibers can load cuprous oxide(Cu2O)particles on the surface.The cuprous oxide is a kind of safe antibacterial material.The copper ions can be reduced into cuprous oxides by reducing agents such as glucose,N2H4 and sodium hypophosphite.The cellulose nanofibers network gel was soaked in CuSO4 solution and filled with copper ions.The cuprous oxide nanoparticles were in situ synthesized by glucose and embedded in cellulose nanofibers network.The morphologies and structure of the composite gel were analyzed by FESEM,FTIR,WAXRD and inductively coupled plasma(ICP).The sizes of Cu2O embedded in cellulose nanofibers network are 200-500 nm wide.The peak at 605 cm−1 attributed to Cu(I)-O vibration of Cu2O shits to 611 cm−1 in the Cu2O/cellulose composite.The Cu2O/cellulose nanofibers composite reveals the obvious characteristic XRD pattern of Cu2O and the results of ICP show that the content of Cu2O in the composite is 13.1%.The antibacterial tests prove that the Cu2O/cellulose nanofibers composite has the high antibacterial activities which is higher against S.aureus than against E.coli. | Ying Hu Qinfei Ke Zhe Li Wanli Han Zhiyong Yan | 2018 | Computers, Materials & Continua2018，，9： | 1 |
| 12 | A novel inhibitor of ARfl and ARv7 induces protein degradation to overcome enzalutamide resistance in advanced prostate cancer显示文摘Enzalutamide(ENZ) is a second-generation androgen receptor(AR) antagonist used for the treatment of castration-resistant prostate cancer(CRPC) and reportedly prolongs survival time within a year of starting therapy. However, CRPC patients can develop ENZ resistance(ENZR), mainly driven by abnormal reactivation of AR signaling, involving increased expression of the full-length AR(ARfl)or dominantly active androgen receptor splice variant 7(ARv7) and ARfl/ARv7 heterodimers. There is currently no efficient treatment for ENZR in CRPC. Herein, a small molecule LLU-206 was rationally designed based on the ENZ structure and exhibited potent inhibition of both ARfl and constitutively active ARv7 to inhibit PCa proliferation and suppress ENZR in CRPC. Mechanically, LLU-206 promoted ARfl/ARv7 protein degradation and decreased ARfl/ARv7 heterodimers through mouse double minute 2-mediated ubiquitination. Finally, LLU-206 exhibited favorable pharmacokinetic properties with poor permeability across the blood-brain barrier, leading to a lower prevalence of adverse effects, including seizure and neurotoxicity, than ENZ-based therapies. In a nutshell, our findings demonstrated that LLU-206 could effectively inhibit ARfl/ARv7-driven CRPC by dual-targeting of ARfl/ARv7 heterodimers and protein degradation, providing new insights for the design of new-generation AR inhibitors to overcome ARfl/ARv7-driven CRPC. | Yan Li Ya Chu Guangjiang Shi Xiaobin Wang Wanli Ye Chun Shan Dajia Wang Di Zhang Wei He Jingwei Jiang Shuqian Ma Yuhong Han Zhili Zhao Shijia Du Zhen Chen Zhiyu Li Yong Yang Chen Wang Xi Xu Hongxi Wu | 2022 | Acta Pharmaceutica Sinica B2022，12，11： | 0 |
| 13 | Triboelectric nanogenerators:the beginning of blue dream显示文摘Wave energy is inexhaustible renewable energy.Making full use of the huge ocean wave energy resources is the dream of mankind for hundreds of years.Nowadays,the utilization of water wave energy is mainly absorbed and transformed by electromagnetic generators(EMGs)in the form of mechanical energy.However,waves usually have low frequency and uncertainty,which means low power generation efficiency for EMGs.Fortunately,in this slow current and random direction wave case,the triboelectric nanogenerator(TENG)has a relatively stable output power,which is suitable for collecting blue energy.This article summarizes the main research results of TENG in harvesting blue energy.Firstly,based on Maxwell’s displacement current,the basic principle of the nanogenerator is expounded.Then,four working modes and three applications of TENG are introduced,especially the application of TENG in blue energy.TENG currently used in blue energy harvesting is divided into four categories and discussed in detail.After TENG harvests water wave energy,it is meaningless if it cannot be used.Therefore,the modular storage of TENG energy is discussed.The output power of a single TENG unit is relatively low,which cannot meet the demand for high power.Thus,the networking strategy of large-scale TENG is further introduced.TENG’s energy comes from water waves,and each TENG’s output has great randomness,which is very unfavorable for the energy storage after large-scale TENG integration.On this basis,this paper discusses the power management methods of TENG.In addition,in order to further prove its economic and environmental advantages,the economic benefits of TENG are also evaluated.Finally,the development potential of TENG in the field of blue energy and some problems that need to be solved urgently are briefly summarized. | Wanli Wang Dongfang Yang Xiaoran Yan Licheng Wang Han Hu Kai Wang | 2023 | Frontiers of Chemical Science and Engineering2023，17，6： | 0 |
| 14 | Synthesis of ultra-narrow PbTe nanorods with extremely strong quantum confinement显示文摘Monodisperse, high-quality, ultra-narrow PbTe nanorods were synthesized for the first time in a one-pot, hot-injection reaction using trans-2-decenoic acid as the agents for lead precursors and tris(diethylamino)phosphine telluride together with free tris(diethylamino)phosphine as the telluride precursors. High monomer reactivity, rapid nucleation and fast growth rate derived from the new precursors led to the anisotropic growth of PbTe nanocrystals at low reaction temperatures(<150℃). In addition, the aspect ratio of PbTe nanorods could be largely adjusted from 4 to 15 by tuning the Pb to Te precursor molar ratio and reaction temperatures. Moreover, the synthesized ultra-narrow PbTe nanorods exhibited extremely strong quantum confinement and presented unique optical properties. We revealed that the diameter and length of PbTe nanorods could significantly affect their optical properties, which potentially offer them new opportunities in the application of optoelectronic and thermoelectric devices and make them desired subjects for multiple exciton generation and other fundamental physics studies. | Lu Han Honghua Fang Chunmiao Du Jianxia Sun Youyong Li Wanli Ma | 2019 | Journal of Materials Science & Technology2019，35，5： | 0 |
| 15 | Seismic Imaging and 3D Architecture of Yongle Atoll of the Xisha Archipelago, South China Sea显示文摘Yongle atoll in the Xisha(Paracel) Archipelago is an isolated carbonate platform developed on Precambrian metamorphic and Mesozoic volcanic rocks since the early Miocene. To identify the 3D stratigraphic architecture and evolution of this platform, 13 high-resolution seismic profiles and shallow-to-deep water multi-beam data were processed and analyzed to reveal seismic facies, sequence boundary reflectors, seismic units, and platform architecture. Nine types of seismic facies were recognized based on their geometry, which included seismic amplitude, continuity, and termination patterns;additionally, six reflections, i.e., Tg, T60, T50, T40, T30, and T20, were identified in the Cenozoic strata. Five seismic units, SQ1(lower Miocene), SQ2(middle Miocene), SQ3(upper Miocene), SQ4(Pliocene), and SQ5(Quaternary), were identified from bottom to top across the platform. The platform grew rapidly in the middle Miocene and backstepped in the late Miocene–Pliocene. Here, we discuss the developmental characteristics and evolution of the Yongle Atoll, in combination with drilling wells, which can be divided into four stages: the initiation stage in the early Miocene, the flourishing stage in the middle Miocene, the partial-drowning stage in the late Miocene–Pliocene, and modern atoll in the Quaternary. | WU Shiguo ZHANG Hanyu QIN Yongpeng CHEN Wanli LIU Gang HAN Xiaohui | 2022 | Acta Geologica Sinica(English Edition)2022，96，5： | 0 |
