| 1 | Guidelines on multidisciplinary approaches for the prevention and management of diabetic foot disease(2020 edition)显示文摘In recent years,as living standards have continued to improve,the number of diabetes patients in China,along with the incidence of complications associated with the disease,has been increasing.Among these complications,diabetic foot disease is one of the main causes of disability and death in diabetic patients.Due to the differences in economy,culture,religion and level of medical care available across different regions,preventive and treatment methods and curative results for diabetic foot vary greatly.In multidisciplinary models built around diabetic foot,the timely assessment and diagnosis of wounds and appropriate methods of prevention and treatment with internal and external surgery are key to clinical practice for this pathology.In 2019,under the leadership of the Jiangsu Medical Association and Chinese Diabetes Society,the writing group for the Guidelines on multidisciplinary approaches for the prevention and management of diabetic foot disease(2020 edition)was established with the participation of scholars from the specialist areas of endocrinology,burn injury,vascular surgery,orthopedics,foot and ankle surgery and cardiology.Drawing lessons from diabetic foot guidelines from other countries,this guide analyses clinical practices for diabetic foot,queries the theoretical basis and grades and gives recommendations based on the characteristics of the pathology in China.This paper begins with assessments and diagnoses of diabetic foot,then describes treatments for diabetic foot in detail,and ends with protections for high-risk feet and the prevention of ulcers.This manuscript covers the disciplines of internal medicine,surgical,nursing and rehabilitation and describes a total of 50 recommendations that we hope will provide procedures and protocols for clinicians dealing with diabetic foot. | Aiping Wang Guozhong Lv Xingbo Cheng Xianghua Ma Wei Wang Jianchao Gui JiHu Meng Lu Guoping Chu Jin’an Chen Hao Zhang Yiqiu Jiang Yuedong Chen Wengbo Yang Lin Jiang Houfa Geng Rendong Zheng Yihui Li Wei Feng Boey Johnson Wenjuan Wang Dalong Zhu Yin Hu | 2020 | Burns & Trauma2020，8，1： | 34 |
| 2 | Meaningful comparison of photocatalytic properties of {001} and {101} faceted anatase TiO2 nanocrystals显示文摘The facet-dependent photocatalytic performance of TiO_2 nanocrystals has been extensively investigated due to their promising applications in renewable energy and environmental fields. However, the intrinsic distinction in the photocatalytic oxidation activities between the {001}and {101} facets of anatase TiO_2 nanocrystals is still unclear and under debate. In this work, a simple photoelectrochemical method was employed to meaningfully quantify the intrinsic photocatalytic activities of {001} and{101} faceted TiO_2 nanocrystal photoanodes. The effective surface areas of photoanodes with different facets were measured based on the monolayer adsorption of phthalic acid on TiO_2 photoanode surface by an ex situ photoelectrochemical method, which were used to normalize the photocurrents obtained from different faceted photoanodes for meaningful comparison of their photocatalytic activities. The results demonstrated that the {001} facets of anatase TiO_2 nanocrystals exhibited much better photocatalytic activity than that of {101} facets of anatase TiO_2 nanocrystals toward photocatalytic oxidation of water and organic compounds with different functional groups(e.g.,–OH, –CHO, –COOH). Furthermore, the instantaneous kinetic constants of photocatalytic oxidation of pre-adsorbates on {001} faceted anatase TiO_2 photoanode are obviously greater than those obtained at {101} faceted anatase TiO_2 photoanode, further verifying the higher photocatalytic activity of {001} facets of anatase TiO_2.This work provided a facile photoelectrochemical method to quantitatively determine the photocatalytic oxidation activity of specific exposed crystal facets of a photocatalyst, which would be helpful to uncover and meaningfully compare the intrinsic photocatalytic activities of different exposed crystal facets of a photocatalyst. | Yang Lu Yipeng Zang Haimin Zhang Yunxia Zhang Guozhong Wang Huijun Zhao | 2016 | Science Bulletin2016，61，13： | 8 |
| 3 | 3-year Treatment of Tenofovir Alafenamide vs.Tenofovir Disoproxil Fumarate for Chronic HBV Infection in China显示文摘Background and Aims:Tenofovir alafenamide(TAF)has similar efficacy to tenofovir disoproxil fumarate(TDF)but with improved renal and bone safety in chronic hepatitis B patients studied outside of China.We report 3-year results from two phase 3 studies with TAF in China(Clinicaltrials.gov:NCT02836249 and NCT02836236).Methods:Chinese hepatitis B e antigen(HBeAg)-positive and-negative chronic hepatitis B patients with viremia and elevated alanine aminotransferase were randomized 2:1 to TAF or TDF treatment groups and treated in a double-blind fashion for 144 weeks(3 years).Efficacy responses were assessed by individual study while safety was assessed by a pooled analysis.Results:Of the 334 patients(180 HBeAg-positive and 154 HBeAg-negative)randomized and treated,baseline characteristics were similar between groups.The overall mean age was 38 years and 73%were male.The mean HBV DNA was 6.4 log10 IU/mL.The median alanine aminotransferase was 88 U/L,and 37%had a history of antiviral use.At week 144,the proportion with HBV DNA<29 IU/mL was similar among the two groups,with TAF at 83%vs.TDF at 79%,and TAF at 93%vs.TDF at 92%for the HBeAg-positive and-negative patients,respectively.In each study,higher proportions of TAF than TDF patients showed normalized alanine aminotransferase(via the American Association for the Study of Liver Diseases and the China criteria)and showed loss of HBsAg;meanwhile,the HBeAg seroconversion rates were similar.Treatment was well-tolerated among the TAF patients,who showed a smaller median decline in creatinine clearance(−0.4 vs.−3.2 mL/min;p=0.014)and less percentage change in bone mineral density vs.TDF at hip(−0.95%vs.−1.93%)and spine(+0.35%vs.−1.40%).Conclusions:In chronic hepatitis B patients from China,TAF treatment provided efficacy similar to TDF but with better renal and bone safety at 3 years. | Jinlin Hou Qin Ning Zhongping Duan You Chen Qing Xie Fu-Sheng Wang Lunli Zhang Shanming Wu Hong Tang Jun Li Feng Lin Yongfeng Yang Guozhong Gong John FFlaherty Anuj Gaggar Shuyuan Mo Cong Cheng Gregory Camus Chengwei Chen Yan Huang Jidong Jia Mingxiang Zhang GS-US-320-0110 and GS-US-320-0108 China Investigators | 2021 | Journal of Clinical and Translational Hepatology2021，9，3： | 7 |
| 4 | Resilience based importance measure analysis for SoS显示文摘In a system of systems(SoS),resilience is an important factor in maintaining the functionality,stability,and enhancing the operation effectiveness.From the perspective of resilience,this paper studies the importance of the SoS,and a resilience-based importance measure analysis is conducted to provide suggestions in the design and optimization of the structure of the SoS.In this paper,the components of the SoS are simplified as four kinds of network nodes:sensor,decision point,influencer,and target.In this networked SoS,the number of operation loops is used as the performance indicator,and an approximate algorithm,which is based on eigenvalue of the adjacency matrix,is proposed to calculate the number of operation loops.In order to understand the performance change of the SoS during the attack and defense process in the operations,an integral resilience model is proposed to depict the resilience of the SoS.From different perspectives of enhancing the resilience,different measures,parameters and the corresponding algorithms for the resilience importance of components are proposed.Finally,a case study on an SoS is conducted to verify the validity of the network modelling and the resiliencebased importance analysis method. | PAN Xing WANG Huixiong YANG Yanjing ZHANG Guozhong | 2019 | Journal of Systems Engineering and Electronics2019，30，5： | 7 |
| 5 | Microblog Burst Keywords Detection Based on Social Trust and Dynamics Model显示文摘Microblog has emerged as a popular medium for providing new sources of information and rapid communications, particularly during burst topics. Burst keywords detection from real-time microblog streams is important for burst topics detection. The exiting algorithms may detect fake burst keywords without taking into account the trustworthiness of the users and human's daily timetable. Our work is the first to combine the trustworthiness of the users with burst keywords detection. We propose a novel approach to detect burst keywords based on social trust and dynamics model. We adapt basic notions of dynamics from physics and model keywords bursts as momentum change of the keywords. On the analogy of physical dynamics model, this approach defines mass as the trustworthiness of user and position as the frequency of keywords. We compute each keyword's burst value by using Moving average convergence/divergence(MACD) and determine whether it is a burst keyword in a given time window. The experimental results on large-scale Sina microblog dataset show that the proposed approach can avoid detecting fake burst keywords. | DONG Guozhong LI Ruiguang YANG Wu WANG Wei GONG Liangyi SHEN Guowei YU Miao LV Jiguang | 2014 | Chinese Journal of Electronics2014，23，4： | 6 |
| 6 | Enhanced Reversible Zinc Ion Intercalation in Deficient Ammonium Vanadate for High-Performance Aqueous Zinc-Ion Battery显示文摘Ammonium vanadate with bronze structure(NH_(4)V_(4)O_(10))is a promising cathode material for zinc-ion batteries due to its high specific capacity and low cost.However,the extraction of NH^(+)_(4) at a high voltage during charge/discharge processes leads to irreversible reaction and structure degradation.In this work,partial NH^(+)_(4) ions were pre-removed from NH_(4)V_(4)O_(10) through heat treatment;NH_(4)V_(4)O_(10) nanosheets were directly grown on carbon cloth through hydrothermal method.Defi-cient NH_(4)V_(4)O_(10)(denoted as NVO),with enlarged interlayer spacing,facilitated fast zinc ions transport and high storage capacity and ensured the highly reversible electrochemical reaction and the good stability of layered structure.The NVO nanosheets delivered a high specific capac-ity of 457 mAh g^(−1) at a current density of 100 mA g^(−1) and a capacity retention of 81%over 1000 cycles at 2 A g^(−1).The initial Coulombic efficiency of NVO could reach up to 97%compared to 85%of NH_(4)V_(4)O_(10) and maintain almost 100%during cycling,indicating the high reaction reversibility in NVO electrode. | Quan Zong Wei Du Chaofeng Liu Hui Yang Qilong Zhang Zheng Zhou Muhammad Atif Mohamad Alsalhi Guozhong Cao | 2021 | Nano-Micro Letters2021，13，8： | 4 |
| 7 | Design and experiment of centralized pneumatic deep precision fertilization device for rice transplanter显示文摘To improve the precision of deep fertilization of paddy fields,a six-row centralized pneumatic deep precision fertilization device for a rice transplanter was designed.This device included a spiral fertilizer distribution system,centralized pneumatic fertilizer delivery system,an opener system,and a fertilization control system.The centralized airflow distribution method was used in the fertilizer delivery system to ensure that the airflow in each fertilizer pipe was evenly distributed.The rotational speeds of the power take-off(PTO)and fertilizer shaft were measured synchronously using photoelectric sensors and matched proportionately in real-time using PID closed-loop control algorithms to achieve precise fertilization rates at each working speed of the rice transplanter.There were two key considerations in the design of the control system to ensure precise fertilization.Firstly,a photoelectric sensor was used to measure the speed of the PTO;the high rotational speed of the PTO could provide a high signal frequency and improve the precision of the measurement of the transplanter’s working speed.Secondly,the fertilizer shaft speed measurement subprogram was set to sleep for a short period to reduce the vibration caused by the engine.During the tests of pneumatic fertilizer delivery system,single-factor tests on airflow distribution methods were conducted.The results showed that the coefficient of variation of the airflow speed for the centralized airflow distribution method was 1.67%,which was the least among the coefficients of the three distribution methods.In the bench tests,the rotational speeds of the fertilizer shaft were set at 10 r/min,20 r/min,30 r/min,and 40 r/min.The maximum coefficient of variation of the fertilization consistency in different rows was 1.49%at the rotational speed of 20 r/min.The maximum coefficient of variation of the fertilization stability was 2.86%at the rotational speed of 40 r/min,while the average fertilizer amount per lap for each distributor was 26.25 g/r.The results of the dynamic fertilization tests showed that the maximum relative error of the fertilizer distribution amount was 2.00%when the target fertilizer rates were 20,30,and 40 kg/667 m2.The results of the field tests showed that the average relative error of the fertilization amount was 3.53%,which satisfies the design standard.This research provides a reference for optimizing pneumatic fertilizer delivery systems and improving fertilization control systems and other pneumatic precision fertilizer application devices. | Xiantao Zha Guozhong Zhang Shijie Zhang Qunxi Hou Yang Wang Yong Zhou | 2020 | International Journal of Agricultural and Biological Engineering2020，13，6： | 3 |
| 8 | 96-Week Treatment of Tenofovir Amibufenamide and Tenofovir Disoproxil Fumarate in Chronic Hepatitis B Patients显示文摘Background and Aims:Tenofovir amibufenamide(TMF)is a novel phosphoramidated prodrug of tenofovir with nonin-ferior efficacy and better bone and renal safety to tenofovir disoproxil fumarate(TDF)in 48 weeks of treatment.Here,we update 96-week comparison results.Methods:Patients with chronic hepatitis B were assigned(2:1)to receive either 25 mg TMF or 300 mg TDF with matching placebo for 96 weeks.The virological suppression was defined as HBV DNA levels<20 IU/mL at week 96.Safety was evaluated thoroughly with focusing on bone,renal,and metabolic pa-rameters.Results:Virological suppression rates at week 96 were similar between TMF and TDF group in both HBeAg-positive and HBeAg-negative populations.Noninferior efficacy was maintained in the pooled population,while it was first achieved in patients with HBV DNA≥7 or 8 log10 IU/mL at baseline.Non-indexed estimated glomerular filtration rate for renal safety assessment was adopted,while a smaller decline of which was seen in the TMF group than in the TDF group(p=0.01).For bone mineral density,patients receiv-ing TMF displayed significantly lower reduction levels in the densities of spine,hip,and femur neck at week 96 than those receiving TDF.In addition,the lipid parameters were stable after week 48 in all groups while weight change still showed the opposite trend.Conclusions:TMF maintained similar efficacy at week 96 compared with TDF with continued superior bone and renal safety profiles(NCT03903796). | Zhihong Liu Qinglong Jin Yuexin Zhang Guozhong Gong Guicheng Wu Lvfeng Yao Xiaofeng Wen Zhiliang Gao Yan Huang Daokun Yang Enqiang Chen Qing Mao Shide Lin Jia Shang Huanyu Gong Lihua Zhong Huafa Yin Fengmei Wang Peng Hu Qiong Wu Chao Pan Wen Jia Chuan Li Chang’an Sun Junqi Niu Jinlin Hou TMF Study Group | 2023 | Journal of Clinical and Translational Hepatology2023，11，3： | 3 |
| 9 | Synergistic catalysis of cluster and atomic copper induced by copper-silica interface in transfer-hydrogenation显示文摘To data,using strong metal-support interaction(SMSI)effect to improve the catalytic performance of metal catalysts is an important strategy for heterogeneous catalysis,and this effect is basically achieved by using reducible metal oxides.However,the formation of SMSI between metal and inert-support has been so little coverage and remains challenge.In this work,the SMSI effect can be effectively extended to the inert support-metal catalysis system to fabricate a Cu^(0)/Cu-doped SiO_(2) catalyst with high dispersion and loading(38.5 wt.%)through the interfacial effect of inert silica.In the catalyst,subnanometric composite of Cu cluster and atomic copper(in the configuration of Cu-O-Si)can be consciously formed on the silica interface,and verified by extended X-ray absorption fine structure(EXAFS),in situ X-ray photoelectron spectroscopy(XPS),and high-angle annular dark field-scanning transmission electron microscopy(HAADF-STEM)characterization.The promoting activity in transfer-hydrogenation by the SMSI effect of Cu-silica interface and the synergistic active roles of cluster and atomic Cu have also been revealed from surface interface structure,catalytic activity,and density functional theory(DFT)theoretical calculation at an atomic level.The subnanometric composite of cluster and atomic copper species can be derived from a facile synthesis strategy of metal-inert support SMSI effect and the realistic active site of Cu-based catalyst can also been identified accurately,thus it will help to expand the application of subnanometric materials in industrial catalysis. | Ruoyu Fan Yange Zhang Zhi Hu Chun Chen Tongfei Shi Lirong Zheng Haimin Zhang Junfa Zhu Huijun Zhao Guozhong Wang | 2021 | Nano Research2021，14，12： | 3 |
| 10 | Converting Co^(2+)-impregnated g-C_(3)N_(4) into N-doped CNTs-confined Co nanoparticles for efficient hydrogenation rearrangement reactions of furanic aldehydes显示文摘The cyclopentanone and derivatives are a class of crucial fine chemicals for various industries and currently produced by conventional petrochemical synthetic routes.Here,we demonstrated a new synthetic approach to directly fabricate N-doped carbon nanotube(N-CNTs)networks with confined Co nanoparticles from Co^(2+)-impregnated bulk g-C_(3)N_(4) as high performance hydrogenation rearrangement(HR)catalyst to efficiently convert a wide spectrum of biomass-derived furanic aldehydes to the corresponding cyclopentanones in water under a record-low H2 pressure of 0.5 MPa and mild temperature.We unveiled a Co-catalysed bulk g-C_(3)N_(4) decomposition/carbonisation CNTs formation mechanism.A new HR pathway was also unveiled. | Dongdong Wang Mohammad Al-Mamun Wanbing Gong Yang Lv Chun Chen Yue Lin Guozhong Wang Haimin Zhang Huijun Zhao | 2021 | Nano Research2021，14，8： | 2 |
| 11 | XAFS study of Cu^(2+) in aqueous solution of CuBr_2显示文摘Copper ion is the essential microelement to many organisms. In this paper, the local structure of Cu2+ in CuBr2 aqueous solutions with different concentrations are investigated by using X-ray absorption fine structure (XAFS) technique. XANES (X-ray Absorption Near Edge Structure) spectra indicate that charge transfer from Br- to Cu2+ decreases with the solution concentration, which lead to a shift of the absorption edge. The shoulder appearing at the rising edge proves to be characteristic of a tetragonal distortion. The Fourier transform magnitudes of EXAFS (Extended X-ray absorption fine structure) data of Cu species suggest that more Cu-Br bonds may exist in high concentrations. A fivefold coordination configuration like a pyramid is used as the fitting parameters. From the analysis of the coordination numbers, the proportion of Cu-O and Cu-Br is 4:1 in the saturated solution. The Br atom is on the equatorial plane of the model. The fitting results agree well with the experiment data. | DAI Binbin WANG Qian MA Jingyuan LI Jiong ZHANG Shuo HUANG Yuying HUANG Wei WU Guozhong ZOU Yang JIANG Zheng XU Hongjie | 2012 | Nuclear Science and Techniques2012，23，3： | 2 |
| 12 | UGGreedy: Influence Maximization for User Group in Microblogging显示文摘We study a new influence maximization problem about how to find a seed set which can maximize the influence spread to a targeted user group in microblogging. To solve this problem, we propose a threestage User group greedy algorithm(UGGreedy) based on user attributes. To reduce network scale, we delete useless user nodes, and rank the rest of users based on user attributes to form a seed candidate set. We employ the seed candidate set to construct a simplified microblogging network graph. We propose a novel influence greedy algorithm based on influence accumulation spread to find the seed set.Experimental results show that UGGreedy can achieve remarkable efficiency on the influence maximization problem for user group in real microblogging networks. | YU Miao YANG Wu WANG Wei SHEN Guowei DONG Guozhong GONG Liangyi | 2016 | Chinese Journal of Electronics2016，25，2： | 2 |
| 13 | The dichotomous and incomplete adaptive immunity in COVID-19 patients with different disease severity显示文摘The adaptive immunity that protects patients from coronavirus disease 2019(COVID-19),caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),is not well characterized.In particular,the asymptomatic patients have been found to induce weak and transient SARS-CoV-2 antibody responses,but the underlying mechanisms remain unknown;meanwhile,the protective immunity that guide the recovery of these asymptomatic patients is elusive.Here,we characterized SARS-CoV-2-specific B-cell and T-cell responses in 10 asymptomatic patients and 64 patients with other disease severity(mild,n=10,moderate,n=32,severe,n=12)and found that asymptomatic or mild symptomatic patients failed to mount virus-specific germinal center(GC)B cell responses that result in robust and prolonged humoral immunity,assessed by GC response indicators including follicular helper T(TFH)cell and memory B cell responses as well as serum CXCL13 levels.Alternatively,these patients mounted potent virus-specific TH1 and CD8+T cell responses.In sharp contrast,patients of moderate or severe disease induced vigorous virus-specific GC B cell responses and associated TFH responses;however,the virus-specific TH1 and CD8+T cells were minimally induced in these patients.These results,therefore,uncovered the protective immunity in asymptomatic patients and also revealed the strikingly dichotomous and incomplete humoral and cellular immune responses in COVID-19 patients with different disease severity,providing important insights into rational design of effective COVID-19 vaccines. | Leiqiong Gao Jing Zhou Sen Yang Lisha Wang Xiangyu Chen Yang Yang Ren Li Zhiwei Pan Jing Zhao Zhirong Li Qizhao Huang Jianfang Tang Li Hu Pinghuang Liu Guozhong Zhang Yaokai Chen Lilin Ye | 2021 | Signal Transduction and Targeted Therapy2021，6，4： | 2 |
| 14 | Clinical study on the related markers of blood coagulation in the patients with ANFH after SARS显示文摘The aim of this research was to investigate the blood coagulation function in the patients with avascular necrosis of the femoral head(ANFH)after severe acute respiratory syndrome(SARS).The expression of CD31,CD61,CD62p,CD63 and PAC-1 on platelet membrane was measured respectively by flowcytometry,and the plasma prothrombin time(PT),activated partial thromboplastin time(APTT),thrombin time(TT)and fibrinogen(Fbg)were mea-sured by blood clotting instrument in 26 patients with ANFH after SARS and in 17 healthy adults.The expression of CD31,CD61,CD 62p,CD63 and PAC-1 on platelet membrane in 26 patients was all lower than that in 17 healthy subjects(P<0.01).The levels of PT,APTT,TT and Fbg in 26 patients were all normal.There is no significant difference(P>0.05)in those markers between patients and 17 healthy adults.The blood may not be in hypercoagulable state in patients with ANFH after SARS. | WU Lianhua GAO Chunjin WANG Guozhong YANG Lin HOU Xiaomin GE Huan XIA Chengqing QI Man | 2007 | Frontiers of Medicine2007，1，4： | 2 |
| 15 | Isotype Heterojunction‑Boosted CO_(2) Photoreduction to CO显示文摘Photocatalytic conversion of CO_(2) to high-value products plays a crucial role in the global pursuit of carbon–neutral economy.Junction photocatalysts,such as the isotype heterojunctions,offer an ideal paradigm to navigate the photocatalytic CO_(2) reduction reaction(CRR).Herein,we elucidate the behaviors of isotype heterojunctions toward photocatalytic CRR over a representative photocatalyst,g-C_(3)N_(4).Impressively,the isotype heterojunctions possess a significantly higher efficiency for the spatial separation and transfer of photogenerated carriers than the single components.Along with the intrinsically outstanding stability,the isotype heterojunctions exhibit an exceptional and stable activity toward the CO_(2) photoreduction to CO.More importantly,by combining quantitative in situ technique with the first-principles modeling,we elucidate that the enhanced photoinduced charge dynamics promotes the production of key intermediates and thus the whole reaction kinetics. | Chaogang Ban Youyu Duan Yang Wang Jiangping Ma Kaiwen Wang Jiazhi Meng Xue Liu Cong Wang Xiaodong Han Guozhong Cao Liyong Gan Xiaoyuan Zhou | 2022 | Nano-Micro Letters2022，14，5： | 2 |
| 16 | Diversity and distribution of soil micro-fungi along an elevation gradient on the north slope of Changbai Mountain显示文摘Elevational changes in patterns of diversity are important to understanding of the influence of global changes, yet few studies have addressed the distribution of microorganisms, e.g. soil micro-fungi. We studied the diversity of the forest soil micro-fungi in four vegetation belts along an elevation gradient on the north slope of Changbai Mountain in Changbai National Nature Reserve.The four belts were characterized as coniferous–deciduous mixed forest, coniferous forest, Erman's birch forest, and alpine tundra. We estimated the quantity and distribution of the fungal species in each belt and calculated three indices,viz. Shannon–Wiener diversity(H'), Pielou's evenness(J'),and Margalef's abundance(E), to depict fungal species diversity. A total of 932 strains were recorded and identified, representing 53 genera, and 108 species. Among these, Penicillium, Aspergillus, Trichoderma, Mucor, Rhizopus and Fusarium were the dominant genera. With increasing elevation, the quantity of fungi and values of H',E, and J' gradually declined. | Hong Yang Guozhong Lu Huiming Jiang Dong-ning Shi Zhiheng Liu | 2017 | Journal of Forestry Research2017，28，4： | 2 |

| 18 | Wire-in-Wire TiO_(2)/C Nanofibers Free-Standing Anodes for Li-Ion and K-Ion Batteries with Long Cycling Stability and High Capacity显示文摘Wearable and portable mobile phones play a critical role in the market, and one of the key technologies is the flexible electrode with high specific capacity and excellent mechanical flexibility. Herein, a wire-in-wire TiO_(2)/C nanofibers (TiO_(2) ww/CN) film is synthesized via electrospinning with selenium as a structural inducer. The interconnected carbon network and unique wire- in-wire nanostructure cannot only improve electronic conductivity and induce effective charge transports, but also bring a superior mechanic flexibility. Ulti-mately, TiO_(2) ww/CN film shows outstanding electrochemical performance as free-standing electrodes in Li/K ion batteries. It shows a discharge capacity as high as 303 mAh g^(−1) at 5 A g^(−1) after 6000 cycles in Li half-cells, and the unique structure is well-reserved after long-term cycling. Moreover, even TiO_(2) has a large diffusion barrier of K^(+), TiO_(2) ww/CN film demonstrates excellent perfor-mance (259 mAh g^(−1) at 0.05 A g^(−1) after 1000 cycles) in K half-cells owing to extraordinary pseudocapacitive contribution. The Li/K full cells consisted of TiO_(2) ww/CN film anode and LiFePO_(4)/Perylene-3,4,9,10-tetracarboxylic dianhydride cathode possess outstanding cycling stability and demonstrate practical application from lighting at least 19 LEDs. It is, therefore, expected that this material will find broad applications in portable and wearable Li/K-ion batteries. | Die Su Yi Pei Li Liu Zhixiao Liu Junfang Liu Min Yang Jiaxing Wen Jing Dai Huiqiu Deng Guozhong Cao | 2021 | Nano-Micro Letters2021，13，7： | 2 |
| 19 | Influence of multi-modality on moving target selection in virtual reality显示文摘Background Owing to recent advances in virtual reality(VR)technologies,effective user interaction with dynamic content in 3D scenes has become a research hotspot.Moving target selection is a basic interactive task in which the user performance research in tasks is significant to user interface design in VR.Different from the existing static target selection studies,the moving target selection in VR is affected by the change in target speed,angle and size,and lack of research on some key factors.Methods This study designs an experimental scenario in which the users play badminton under the condition of VR.By adding seven kinds of modal clues such as vision,audio,haptics,and their combinations,five kinds of moving speed and four kinds of serving angles,and the effect of these factors on the performance and subjective feelings in moving target selection in VR,is studied.Results The results show that the moving speed of the shuttlecock has a significant impact on the user performance.The angle of service has a significant impact on hitting rate,but has no significant impact on the hitting distance.The acquisition of the user performance by the moving target is mainly influenced by vision under the combined modalities;adding additional modalities can improve user performance.Although the hitting distance of the target is increased in the trimodal condition,the hitting rate decreases.Conclusion This study analyses the results of user performance and subjective perception,and then provides suggestions on the combination of modality clues in different scenarios. | Yang LI Dong WU Jin HUANG Feng TIAN Hong'an WANG Guozhong DAI | 2019 | Virtual Reality & Intelligent Hardware2019，1，3： | 1 |
