| 1 | High-power High-efficient and Simplified High-frequency Switching Power Supply for Electrolytic Plating显示文摘针对大功率电解电镀开关电源的输入整流级引起的无功和谐波等电能质量问题,研究了一种基于高效PWM整流的高频开关电源。该电源前级整流器仅用4个开关管来进行PWM整流,后级采用半桥逆变器进行高频变换,显著减少了开关数量。针对三相四开关PWM整流器,推导一种基于开关模型的无差拍控制方法,该方法可实现系统的快速、无差整流。针对多台开关电源的并联均流问题,提出一种基于虚拟阻抗的自均流控制方法,可实现多台电源的均流稳定运行。通过仿真与实验验证了所提结构和控制方法的正确性。 | MA Fujun LUO An XIAO Huagen | 2012 | 中国电机工程学报2012，32，21： | 6 |
| 2 | Dual quaternion based virtual hand interaction modeling显示文摘Virtual hands play key roles in three-dimensional interaction in various virtual reality applications.However,their visual realism has seldom been seriously discussed in the community of human computer interaction,not to mention the challenging balance between their visual/motion realism and real-time performance.In this paper,a novel approach for virtual hand interaction modeling based on dual quaternion is proposed.Specifically,dual quaternion blending(DQB) is introduced as pseudo muscular layer of our virtual hand model instead of traditional linear blending(LB) and quaternion blending(QB) due to its advantages in muscular deformation.A framework for virtual hand interaction is proposed which supports both gesture interactions and 3D manipulations.Experimental results show that our proposed virtual hand interaction model is suitable for most virtual reality applications and achieves good visual/motion realism while maintains real-time performance. | CHEN WenFeng ZHU ShuJing WAN HuaGen FENG JieQing | 2013 | Science China(Information Sciences)2013，56，3： | 6 |
| 3 | MOF-derived ZnCo_2O_4/C wrapped on carbon fiber as anode materials for structural lithium-ion batteries显示文摘To meet the requirements for the mechanical and electrochemical performance for carbon fiber-based (CF-based) composites in the structural lithium ion batteries (SLIBs) application, better CF-Based composites are urgently needed. Herein, we report a novel composite metal organic framework (MOF)-derived ZnCo_2 O_4/C@carbon fiber via a facile method and subsequent annealing treatment. In this anode,the nano ZnCo_2 O_4/C coatings wrapped on the surface of CF provide more active sites for electrode reactions and the thin carbon layers give the additional protection. For this material, after 100 cycles, it exhibits excellent cycling stability including high reversible capacity of 463 mAh/g at 50 mA/g, which increases 201% than that of the CF. Thus, this structural anode material exhibits enhanced capacity, high initial columbic efficiency. | Huagen Li Shubin Wang Mengjie Feng Jiping Yang Boming Zhang | 2019 | Chinese Chemical Letters2019，30，2： | 4 |
| 4 | Magnetic Fe_(2)O_(3)/biochar composite prepared in a molten salt medium for antibiotic removal in water显示文摘The large-scale use of antibiotics is causing serious water pollution problems,and it is of great significance to develop new technologies to remove antibiotics from water.As an environmentally friendly and economical adsorption material,carbon derived from biomass is a low-cost and feasible material for removing antibiotics in sewage,but the current removal efficiencies are not high enough for large-scale practical application.In this study,poplar wood chips are used as raw material,and a magnetic biochar is prepared by co-pyrolysis of poplar wood chips and FeCl_(3)/CaCl_(2)mixed molten salt.X-ray diffraction(XRD),Fourier transform infrared spectroscopy(FTIR),N_(2)-isothermal adsorption and desorption,X-ray photoelectron spectroscopy(XPS)and scanning electron microscope(SEM)techniques showed the successful synthesis of Fe_(2)O_(3)/bioC composite.In-situ formed Fe_(2)O_(3)makes the biochar possess the characteristic of superparamagnetic,which is conducive to the recycling of biochar.Due to the etching effect of the molten salts,rough surface was formed on Fe_(2)O_(3)/bioC,result-ing in a maximum norfloxacin(NOR)adsorption ability up to 38.77 mg g^(−1)at pH 6.0.The NOR adsorption behavior on Fe_(2)O_(3)/bioC followed the pseudo second order kinetic model and the equilibrium data was best fitted the Langmuir model.In addition,the adsorption process of NOR on Fe_(2)O_(3)/bioC was thermodynamically spontaneous.The results show that this low-cost and reusable magnetic biochar has the potential for rapid and efficient removal of antibiotic from aqueous solution. | Huagen Liang Chenxi Zhu Shan Ji Palanisamy Kannan Fu Chen | 2022 | Biochar2022，4，1： | 4 |
| 5 | Real-time camera tracking using hybrid features in mobile augmented reality显示文摘Often only simple features are employed in mobile augmented reality(AR) due to the limited computational capacity of mobile terminals, which often leads to unsteadiness of the camera tracking. In this paper, we propose a novel approach to real-time camera tracking in mobile AR using hybrid features to alleviate this problem. By integrating feature points and lines as scene features, hybrid features are generated through the process of point/line features extraction, optimization and fusion, and are used in the real-time estimation of camera parameters. A method for image feature optimization is proposed based on the scene structural analysis to meet the computational constraints of mobile terminals. In order to improve the stability of camera tracking, an iterative screening method is proposed to choose a set of stable feature lines, and hybrid features are adaptively constructed based on the composition and geometry of scene features. It is shown from the experimental results that the proposed method produces more stable and smoother camera trajectories in comparison with the method only using feature points, and a good balance is achieved between the stability and the real-time computation of the camera tracking on a mobile platform. | WANG WeiJie WAN HuaGen | 2015 | Science China(Information Sciences)2015，58，11： | 2 |
| 6 | Effective remediation of organic-metal co-contaminated soil by enhanced electrokinetic-bioremediation process显示文摘This work investigates the influence of electrokinetic-bioremediation(EK-BIO)on remediating soil polluted by persistent organic pollutants(POPs)and heavy metals(mainly Cu,Pb and Ni),originated from electronic waste recycling activity.The results demonstrate that most of POPs and metals were removed from the soil.More than 60%of metals and 90%of POPs in the soil were removed after a 30-day EK-BIO remediation assisted by citrate.A citrate sodium concentration of 0.02 g/L was deemed to be suitable because higher citrate did not significantly improve treatment performance whereas increasing dosage consumption.Citrate increased soil electrical current and electroosmotic flow.After remediation,metal residues mainly existed in stable and low-toxic states,which could effectively lower the potential hazard of toxic metals to the surrounding environment and organisms.EK-BIO treatment influenced soil microbial counts,dehydrogenase activity and community structure. | Fu Chen Qi Zhang Jing Ma Qianlin Zhu Yifei Wang Huagen Liang | 2021 | Frontiers of Environmental Science & Engineering2021，15，6： | 2 |

| 13 | Facile synthesis of NiAl_(2)O_(4)/g-C_(3)N_(4) composite for efficient photocatalytic degradation of tetracycline显示文摘Designing high-efficiency photocatalysts responsive to visible light is important for the degradation of antibiotics in water.Heterojunction engineering is undoubtedly an effective strategy to improve the photocatalytic performance.In this work,spinel-type metal oxides(NiAl_(2)O_(4),NAO)are synthesized by a simple sol-gel and calcination process.After compounding graphitic carbon nitride(g-C_(3)N_(4)),NAO/g-C_(3)N_(4) heterojunction is obtained,which then is used as the photocatalyst for tetracycline hydrochloride(TC).The effects of photocatalyst dosage,the initial concentration of TC,and solution pH on photodegradation performance are systematically studied.The removal rate of TC on NAO/g-C_(3)N_(4) reach up to∼90%after visible light irradiation for 2 hr and the degradation rate constant is∼7 times,and∼32 times higher than that of pure NAO and g-C_(3)N_(4).The significantly improved photocatalytic activity can be attributed to the synergistic effect between well matched energy levels in NAO/g-C_(3)N_(4) heterojunctions,improvement of interfacial charge transfer,and enhancement of visible light absorption.This study provides a way for the synthesis of efficient photocatalysts and an economic strategy for removing antibiotics contamination in water. | Huagen Liang Chenxi Zhu Anhu Wang Kannan Palanisamy Fu Chen | 2023 | Journal of Environmental Sciences2023，，5： | 1 |
