| 1 | Research progress on silicon/carbon composite anode materials for lithium-ion battery显示文摘Silicon(Si) has been considered as one of the most promising anode material for the next generation lithium-ion batteries(LIBs) with high energy densities, due to its high theoretical capacity, abundant availability and environmental friendliness. However, silicon materials with low intrinsic electric and ionic conductivity suffer from huge volume variation during lithiation/delithiation processes leading to the pulverization of Si and subsequently resulting in severe capacity fading of the electrodes. Coupling of Si with carbon(C) realizes a favorable combination of the two materials properties, such as high lithiation capacity of Si and excellent mechanical and conductive properties of C, making silicon/carbon composite(Si/C) ideal candidates for LIBs anodes. In this review, recent progresses of Si/C materials utilized in LIBs are summarized in terms of structural design principles, material synthesis methods, morphological characteristics and electrochemical performances by highlighting the material structures. The mechanisms behind the performance enhancement are also discussed. Moreover, other factors that affect the performance of Si/C anodes, such as prelithiation, electrolyte additives, and binders, are also discussed. We aim to present a full scope of the Si/C-based anodes, and help understand and design future structures of Si/C anodes in LIBs. | Xiaohui Shen Zhanyuan Tian Ruijuan Fan Le Shao Dapeng Zhang Guolin Cao Liang Kou Yangzhi Bai | 2018 | Journal of Energy Chemistry2018，27，4： | 29 |
| 2 | Research of Compound Controller for Flight Simulator with Disturbance Observer显示文摘A compound controller is proposed to alleviate the considerable chattering in output of zero phase error tracking controller (ZPETC), when the flight simulator losses command data of simulation signal. Besides, the shortcomings, caused by conventional differential methods in retrieving velocity and acceleration signals, are avoided to a certain extent. The compound controller based on disturbance observer (DOB) is composed of a feed-forward controller and a feedback controller. It estimates velocity and acceleration of unknown tracking signal, and also velocity response with an approximate method for differential. The experiments on a single-axis flight simulator show that the proposed method has strong robustness against parameter perturbations and external disturbances, owing to the introduced DOB. Compared with the scheme with ZPETC, the proposed scheme possesses more simple design and better tracking performance. Moreover, it is less sensitive to position command distortion of flight simulator. | WU Yunjie LIU Xiaodong TIAN Dapeng | 2011 | Chinese Journal of Aeronautics2011，24，5： | 10 |
| 3 | Elevated 8-oxo-7,8-dihydro-2'-deoxyguanosine in genome of T24 bladder cancer cells induced by halobenzoquinones显示文摘Halobenzoquinones(HBQs) are an emerging class of halogenated disinfection byproducts(DBPs) in drinking water, which raised public concerns due to potential carcinogenic effects to human bladder. Our previous work demonstrated that HBQs and hydrogen peroxide(H_2O_2)together generated oxidative DNA damage via a metal-independent and intercalationenhanced oxidation mechanism in vitro. This study further investigated the efficiency of various HBQs to induce oxidative DNA damage in T24 bladder cancer cells. Compared with T24 cells without treatment(3.1 lesions per 10~6 d G), the level of 8-oxo-7,8-dihydro-2′-deoxyguanosine(8-oxod G) significantly increased by 1.4, 3.2, 8.8, and 9.2 times after treatment with tetrabromo-1,4-benzoquinone(TBBQ), terachloro-1,4-benzoquinone(TCBQ),2,6-dichloro-1,4-benzoquinone(2,6-DCBQ) and 2,5-dichloro-1,4-benzoquinone(2,5-DCBQ) for24 hr, respectively. Interestingly, we found that the oxidative potency of HBQs in T24 cells(2,5-DCBQ ≈ 2,6-DCBQ > TCBQ > TBBQ) is inconsistent with that of in vitro ds DNA oxidation(TCBQ > TBBQ > 2,5-DCBQ > 2,6-DCBQ), suggesting HBQs induce oxidative lesions in cellular genomic DNA probably involved with a complex mechanism. | Tian Xu Junfa Yin Shaokun Chen Dapeng Zhang Hailin Wang | 2018 | Journal of Environmental Sciences2018，30，1： | 5 |

The following indicators was realized: the output pulse current amplitude can be up to 100 A, the shortest pulse rise / fall time was 18.8 ns and 16.1 ns respectively when the maximum amplitude output, the pulse width could be narrowest to 40 ns, repetition frequency could achieve 10 Hz to 10 k Hz, MOSFET switching losses decreased by 30.9 %. This pulsed current source can be used, not only as the power supply for the ordinary high speed narrow pulse width laser diode, but also as an ideal drive power for the high energy, narrow width pulse laser diode. | Tian Xiaojian Zhang Dapeng Mudare Joseph Gao Fubin | 2016 | The Journal of China Universities of Posts and Telecommunications2016，23，2： | 4 |
| 5 | Remote collaborative pseudo-dynamic testing system based on acquisition board control显示文摘In this paper, NetSLab network platform for remote collaborative pseudo-dynamic testing, which was developed recently by a research group led by the Hunan University, is presented. Aiming at MTS system which is widely used in structural testing, the control method with acquisition board was investigated in this study to realize the communication interface between NetSLab and MTS system, and open up the remote collaborative pseudo-dynamic testing system. Using the developed testing system, a collaborative pseudo-dynamic testing on LAN was carried out successfully. The result manifests that the data transmission and collaborative control can be implemented accurately between NetSLab and MTS system, so that the usability of the testing system is validated. | Wang Dapeng Tian Shizhu | 2007 | Progress in Natural Science:Materials International2007，17，12： | 2 |

| 10 | Redesigned Duplex RT-qPCR for the Detection of GI and GII Human Noroviruses显示文摘Human noroviruses(HuNoVs)are major foodborne pathogens that cause nonbacterial acute gastroenteritis worldwide.As the tissue-culture system for HuNoVs is not mature enough for routine detection of the virus,detection is mainly dependent on molecular approaches such as reverse transcription polymerase chain reaction(RT-PCR)and reverse transcription quantitative real-time polymerase chain reaction(RTqPCR).The widely used primers and probes for RT-qPCR were established in the early 2000s.As HuNoVs are highly variant viruses,viral genome mutations result in previously designed primers and/or probes that were perfectly matched working less efficiently over time.In this study,a new duplex RT-qPCR(ND-RT-qPCR)was designed for the detection of genogroup Ⅰ(GⅠ)and genogroup Ⅱ(GⅡ)HuNoVs based on an analysis of viral sequences added in the database after 2010.Using long transcribed viral RNAs,the results demonstrate that the sensitivity of ND-RT-qPCR is as low as one genomic copy for both GⅠ and GⅡ HuNoVs.The performance of ND-RT-qPCR was further evaluated by a comparison with the commonly used Kageyama primer/probe sets for RT-qPCR(Kageyama RT-qPCR)for 23 HuNoV-positive clinical samples.All five GⅠ samples were registered as positive by ND-RT-qPCR,whereas only two samples were registered as positive by Kageyama RT-qPCR.All 18 GⅡ samples were registered as positive by ND-RT-qPCR,while 17 samples were registered as positive by Kageyama RT-qPCR.The sensitivity reflected by the quantification cycle(Cq)value was lower in ND-RT-qPCR than in Kageyama RT-qPCR.Our data suggest that ND-RT-qPCR could be a good fit for the detection of current strains of HuNoVs. | Danlei Liu Zilei Zhang Qingping Wu Peng Tian Haoran Geng Ting Xu Dapeng Wang | 2020 | Engineering2020，6，4： | 0 |
