| 2 | Economy Analysis of Flexible LCC-HVDC Systems with Controllable Capacitors显示文摘Commutation failure(CF)is a frequent dynamic event at inverter of LCC-HVDC systems caused by AC side faults which can lead to inverter blocking,interruption of active power transfer,and even system blackout.To eliminate CFs and improve system performance,new Flexible LCC-HVDC topologies have been proposed in previous research but with limited analysis on its economic performance.Therefore,to further validate the applicability of Flexible LCC-HVDC topologies,this paper utilizes Life-Cycle Cost Analysis model to analyze the life-cycle cost of inverter stations for conventional LCCHVDC,Capacitor Commutated Converter based HVDC(CCCHVDC)topology and Flexible LCC-HVDC topologies including Controllable Capacitor based Flexible LCC-HVDC,AC Filterless Controllable Capacitor based Flexible LCC-HVDC and improved Flexible LCC-HVDC.Through a case study based on a 500 kV,1000 MW LCC-HVDC scheme,comparison results show that the AC Filterless Controllable Capacitor based Flexible LCCHVDC topology and the improved Flexible LCC-HVDC topology have lower cost than the conventional LCC-HVDC and CCCHVDC topologies,which proves that the elimination of CFs can be achieved with reduced cost. | Nan Chen Kunpeng Zha Haitao Qu Fangling Li Ying Xue Xiao-Ping Zhang | 2022 | CSEE Journal of Power and Energy Systems2022,8,6: | 2 |
| 3 | Bioactivated in vivo assembly(BIVA)peptide-tetraphenylethylene(TPE)probe with controllable assembled nanostructure for cell imaging显示文摘The emergence of fluorescent light-up molecular probe,which can specifically turn on their fluorescent in the presence of stimulation factors,has open up a new opportunity to advance biosensing and bioimaging.In this work,we designed and synthesized a peptide-AIE conjugate probe for cell imaging with controlled in situ assembled nanostructures.The modular designed probe is consisted of a selfassembled peptide-tetraphenylethene(TPE)motif,a fibroblast activation protein alpha(FAP-α)responsive motif,a hydrophilic motif and a targeting motif.The probe exhibits typically turn-on fluorescence property specifically triggered by FAP-α,which is a significant overexpressed membrane protein on pancreatic tumor cells.Interestingly,the peptide modified the TPE dramatically impacts the assembled nanostructure,which can be modulated by peptide sequences.As a result,the peptide FF(PhePhe)modification of TPE as the self-assembled motif provides a suitable balance of the probe with lightup property and nanofiber assembled structure in situ.Finally,our probe could effectively detect the FAP-αon tumor cells with high specificity.Meantime,the nanofibers in situ assembled on the surface of CAFs enhanced the probe accumulation and prolonged the retention for cell imaging.We envision that this study may inspire new insights into the design of nanostructure controlled AIE light-up bio-probe. | Shizhao Lu Xiaoyan Guo Fangling Zhang Xiaodong Li Meishuai Zou Li-Li Li | 2021 | Chinese Chemical Letters2021,32,6: | 2 |
| 4 | Hydrogen-assisted scalable preparation of ultrathin Pt shells onto surfactant-free and uniform Pd nanoparticles for highly efficient oxygen reduction reaction in practical fuel cells显示文摘Concentrating active Pt atoms in the outer layers of electrocatalysts is a very effective approach to greatly reduce the Pt loading without compromising the electrocatalytic performance and the total electrochemically active surface area(ECSA)for the oxygen reduction reaction(ORR)in hydrogen-based proton-exchange membrane fuel cells.Accordingly,a facile,low-cost,and hydrogen-assisted two-step method is developed in this work,to massively prepare carbon-supported uniform,small-sized,and surfactant-free Pd nanoparticles(NPs)with ultrathin~3-atomic-layer Pt shells(Pd@Pt_(3L) NPs/C).Comprehensive physicochemical characterizations,electrochemical analyses,fuel cell tests,and density functional theory calculations reveal that,benefiting from the ultrathin Pt-shell nanostructure as well as the resulting ligand and geometric effects,Pd@Pt_(3L) NPs/C exhibits not only significantly enhanced ECSA,electrocatalytic activity,and noble-metal(NM)utilization compared to commercial Pt/C,showing 81.24 m^(2)/gPt,0.710 mA/cm^(2),and 352/577 mA/mgNM/Pt in ECSA,area-,and NM-/Pt-mass-specific activity,respectively;but also a much better electrochemical stability during the 10,000-cycle accelerated degradation test.More importantly,the corresponding 25-cm^(2) H2-air/O_(2) fuel cell with the low cathodic Pt loading of~0.152 mgPt/cm^(2)geo achieves the high power density of 0.962/1.261 W/cm^(2)geo at the current density of only 1,600 mA/cm^(2)geo,which is much higher than that for the commercial Pt/C.This work not only develops a high-performance and practical Pt-based ORR electrocatalyst,but also provides a scalable preparation method for fabricating the ultrathin Pt-shell nanostructure,which can be further expanded to other metal shells for other energy-conversion applications. | Liuxuan Luo Cehuang Fu Aiming Wu Zechao Zhuang Fengjuan Zhu Fangling Jiang Shuiyun Shen Xiyang Cai Qi Kang Zhifeng Zheng Chenyi Hu Jiewei Yin Guofeng Xia Junliang Zhang | 2022 | Nano Research2022,15,3: | 2 |

| 6 | Adsorption and desorption of Cd in reclaimed soil under the influence of humic acid:characteristics and mechanisms显示文摘Exogenous humus can change the content and migration activity of cadmium(Cd)in soil.Humic acid(HA)is an important soluble humus component in soil.In order to explore the relationship between cadmium pollution mechanism and ecological environment of humic acid in reclaimed soil,the characteristics of humic acid adsorbing cadmium in alkaline conditions were studied.This study employed reclaimed soil from the Huainan mining area,China.The adsorption and desorption characteristics as well as influence mechanisms on the heavy metal cadmium(Cd)were explored under the influence of HA.The results show that:(1)When Cd concentration was low(0.2–10 mg/L),HA had little effect on Cd adsorption and desorption in reclaimed soil.When the Cd concentration was high(15–80 mg/L),HA had a great influence on the adsorption and desorption of Cd in reclaimed soil.The addition of HA can inhibit the adsorption of Cd by reclaimed soil and effectively improve the desorption capacity of Cd by reclaimed soil.(2)The kinetic curves of Cd adsorption and desorption of reclaimed soil with added HA show that both processes(adsorption and desorption)include two stages:rapid reaction and slow reaction.The adsorption of Cd by reclaimed soil under the influence of HA was 18.18%lower than that of normal reclaimed soil,and the increase of Cd desorption was 50.29%.(3)The factors affecting the adsorption and desorption of Cd in the soil were analyzed with gray theory,and their importance can be ordered as follows:Cd concentration>HA concentration>pH>temperature.Considering the influence of HA,a multi-factor coupling function model of adsorption and desorption of Cd in soil is established.This model provides theoretical guidance for the scientific prediction and evaluation of Cd environmental pollution risks in soil and will be useful for developing a new solution for engineering remediation of high concentration Cd contaminated soil. | Yonghong Zheng Zhiguo Zhang Yongchun Chen Shikai An Lei Zhang Fangling Chen Chengnan Ma Weiqing CAi | 2022 | International Journal of Coal Science & Technology2022,9,1: | 1 |
| 7 | Applications and recent advances in transdermal drug delivery systems for the treatment of rheumatoid arthritis显示文摘Rheumatoid arthritis is a chronic,systemic autoimmune disease predominantly based on joint lesions with an extremely high disability and deformity rate.Several drugs have been used for the treatment of rheumatoid arthritis,but their use is limited by suboptimal bioavailability,serious adverse effects,and nonnegligible first-pass effects.In contrast,transdermal drug delivery systems(TDDSs)can avoid these drawbacks and improve patient compliance,making them a promising option for the treatment of rheumatoid arthritis(RA).Of course,TDDSs also face unique challenges,as the physiological barrier of the skin makes drug delivery somewhat limited.To overcome this barrier and maximize drug delivery efficiency,TDDSs have evolved in terms of the principle of transdermal facilitation and transdermal facilitation technology,and different generations of TDDSs have been derived,which have significantly improved transdermal efficiency and even achieved individualized controlled drug delivery.In this review,we summarize the different generations of transdermal drug delivery systems,the corresponding transdermal strategies,and their applications in the treatment of RA. | Yuyi Xu Ming Zhao Jinxue Cao Ting Fang Jian Zhang Yanli Zhen Fangling Wu Xiaohui Yu Yaming Liu Ji Li Dongkai Wang | 2023 | Acta Pharmaceutica Sinica B2023,13,11: | 0 |
| 8 | Efficient synthesis of forsterite via high-temperature thermochemical reactions from boron mud waste without briquetting显示文摘Forsterite is a highly demanded material in high-temperature industries due to its superior performance in elevated temperatures.This study proposes synthesizing high-quality forsterite via high-temperature thermochemical reactions using abundant boron mud waste.The new synthesis method capitalizes on the high reactivity of fine raw powder materials,enabling the reaction to reach completion at low temperatures rapidly.The chemical characteristics,microscopic morphology,and structure of synthe-sized samples are systematically studied using XRD and SEM.The results confirm that boron mud can be efficiently transformed into forsterite after 10 min of reactions at 1500℃.The synthesized products attain over 98.7%densification and contain more than 85.0%forsterite with well-developed grains.The activation energy of forsterite grain growth in the 1100-1500℃temperature range is 165.5 kJ/mol.This study provides a low-cost method for producing forsterite and an efficient and environmentally friendly solution for treating solid waste. | Fangling Hu Liangliang Fu Qingjin Zhang Guangwen Xu Dingrong Bai | 2024 | Particuology2024,87,4: | 0 |
| 9 | Dispersion hydrophobic electrolyte enables lithium-oxygen battery enduring saturated water vapor显示文摘Li-O_(2) batteries gain widespread attention as a can didate for next-generati on energy storage devices due to their extraordinary theoretic specific energy.The semi-open structure of Li-O_(2) batteries causes many parasitic reactions,especially related to water.Water is a double-edged sword,which destroys Li anode and simultaneously triggers a solution-based pathway of the discharge product.In this work,hexamethyldisilazane(HMDS)is introduced into the electrolyte of an aprotic Li-O_(2) battery.HMDS has a strong ability to combine with a trace of water to gen erate a hydrophobic hexamethyldisiloxa ne(MM),which eliminates water from the electrolyte decomposition and then prevents the Li anode from producing the insulating LiOH with water.In this case,the hydrophobic MM disperses in the ether-based electrolyte,forming a dispersion hydrophobic electrolyte.This electrolyte can anchor water from the environment on the cathode side,which triggers a solution-based pathway and regulates the growth morphology of the discharge product and consequently increases the discharge capacity.Compared with the Li-O_(2) battery without the HMDS,the HMDS-containing Li-O_(2) battery contributes an about 13-fold increase of cyclability(400 cycles,1800 h)in the extreme environment of saturated water vapor.This work opens a new approach for directly operating aprotic Li-O_(2) batteries in ambient air. | Yinan Zhang Fangling Jiang Hao Jiang Osamu Yamamoto Tao Zhang | 2022 | Journal of Energy Chemistry2022,31,1: | 0 |
| 10 | Protective effects of Achyranthes bidentata polypeptides on retinal ganglion cells post-optic nerve crush in rats显示文摘Achyranthes bidentata polypeptides(ABPP) have been reported to inhibit apoptosis of retinal ganglion cells(RGCs).The present study investigated the protective effects of ABPP on RGCs in a rat model of optic nerve injury.With prolonged injury time,RGC densities were gradually decreased.ABPP(5 μg) significantly increased RGC densities and upregulated growth associated protein 43 expression in rats with optic nerve injury.Results demonstrate that ABPP can protect RGCs and promote axonal growth after optic nerve crush. | Nan Hu Qi Zhao Fangling Zhang Junfang Zhang Xiaosong Gu | 2011 | Neural Regeneration Research2011,6,15: | 0 |
| 11 | Room temperature in-situ preparation of hydrazine-linked covalent organic frameworks coated capillaries for separation and determination of polycyclic aromatic hydrocarbons显示文摘Covalent organic frameworks(COFs)have been increasingly used in capillary electrochromatography due to their excellent characteristics.In this work,hydrazine-linked TFPB-DHzDS(TFPB:1,3,5-tris(4-formylphenyl)benzene;DHzDS:2,5-bis(3-(ethylthio)propoxy)terephthalohydrazide)was first synthesized by a simpler and easier method at room temperature and introduced into capillary electrochromatography as coating material.The TFPB-DHzDS coated capillaries were prepared by an in-situ growth process at room temperature.After optimizing the coating concentration and experimental conditions of capillary electrochromatography,baseline separation of two groups of polycyclic aromatic hydrocarbons was achieved based on the TFPB-DHzDS coated capillary.And the established method was used successfully to determine PAHs in natural water and soil samples.The spiked recoveries of polycyclic aromatic hydrocarbons in these samples ranged from 90.01%to 111.0%,indicating that the method is reliable and could detect polycyclic aromatic hydrocarbons in natural samples.Finally,molecular simulation was applied to study and visualize the interaction between the analytes and coating COF materials to investigate the molecular level separation mechanism further. | Yanli Zhang Wenjuan Lv Fangling Wang Xiao Niu Guoxiu Wang Xuequan Wu Xiaoyun Zhang Xingguo Chen | 2023 | Frontiers of Chemical Science and Engineering2023,17,5: | 0 |

| 14 | Influence of Fe on electrocatalytic activity of iron-nitrogendoped carbon materials toward oxygen reduction reaction显示文摘The development of highly active nitrogendoped carbon-based transition metal(M-N-C)compounds for the oxygen reduction reaction(ORR)in proton exchange membrane fuel cells(PEMFCs)greatly helps reduce fuel cell cost,thus rapidly promoting their commercial applications.Among different M-N-C electrocatalysts,the series of Fe-N-C materials are highly favored because of their high ORR activity.However,there remains a debate on the effect of Fe,and rare investigations focus on the influence of Fe addition in the second heat treatment usually performed after acid leaching in the catalyst synthesis.It is thus very critical to explore the influences of Fe on the ORR electrocatalytic activity,which will,in turn,guide the design of Fe-N-C materials with enhanced performance.Herein,a series of Fe-N-C electrocatalysts are synthesize and the influence of Fe on the ORR activity are speculated both experimentally and theoretically.It is deduced that the active site lies in the structure of Fe-N4,accompanied with the addition of appropriate Fe,and the number of active sites increases without the occurrence of agglomeration particles.Moreover,it is speculated that Fe plays an important role in stabilizing N as well as constituting active sites in the second pyrolyzing process. | Lin LI Cehuang FU Shuiyun SHEN Fangling JIANG Guanghua WEI Junliang ZHANG | 2022 | Frontiers in Energy2022,16,5: | 0 |
