| 1 | Cobalt(Ⅱ)coordination polymers as anodes for lithium-ion batteries with enhanced capacity and cycling stability显示文摘Coordination polymer Co-btca(H4 btca = 1,2,4,5-benzenetetracarboxylic acid) was synthesized using a simply hydrothermal method.In particular,the as-prepared Co-btca was applied as an anode material for lithium-ion battery for the first time.Single crystal X-ray diffraction results indicated that the asprepared Co-btca displayed unique layer structure,which was beneficial to transport Li ions and electrons.Also,owing to the porous structure and appropriate specific surface area,Co-btca electrode delivered a reversible capacity of 801.3 m A h/g after 50 cycles at a current density of 200 m A/g.The reversible capacity of 773.9 m A h/g was maintained after 200 cycles at a current density of 500 m A/g,exhibiting enhanced cycle stability.It also showed improved rate performance,making it a promising anode material and a new choice for lithium-ion batteries. | Yumei Luo Lixian Sun Fen Xu Siyue Wei Qingyong Wang Hongliang Peng Chonglin Chen | 2018 | Journal of Materials Science & Technology2018，34，8： | 1 |

| 4 | ARRB2 promotes colorectal cancer growth through triggering WTAP显示文摘Colorectal cancer (CRC) is one of the most lethal cancers worldwide. The expression of β-arrestin2 (β-Arr2, ARRB2) in CRC has been well investigated;however, its exact mechanism causing the cancer progression remains unclear. In this study, we discovered that the expression level of ARRB2 was significantly upregulated in CRC as compared to the normal tissues by employing the Cancer Genome Atlas (TCGA) data, western blot analysis, and immunohistochemistry. Furthermore, the level of ARRB2 was correlated with the patients’ overall survival by Kaplan–Meier analysis. The higher expression of ARRB2 promoted CRC cell growth, enhanced the cell motility, and blocked cell apoptosis, which is crucial for tumor growth. Lastly, the suppression of ARRB2 expression was enough to attenuate the progression of CRC induced by azoxymethane/dextran sodium sulfate. Interestingly, we also found that the knockdown of ARRB2 decreased several cancer pathways mediated by the expression of Wilms tumor 1 associated protein (WTAP), which led to the inhibition of cell proliferation and migration. Altogether, our results demonstrated that ARRB2 promoted the growth and migration of CRC cells by regulating the WTAP expression. | Hongguang Liang Zelong Lin Youqiong Ye Rongcheng Luo Lixian Zeng | 2021 | Acta Biochimica et Biophysica Sinica2021，53，1： | 1 |
| 5 | An Efficient Sleep Spindle Detection Algorithm Based on MP and LSBoost显示文摘Sleep spindles are an electroencephalogram(EEG)biomarker of non-rapid eye movement(NREM)sleep and have important implications for clinical diagnosis and prognosis.However,it is challenging to accurately detect sleep spindles due to the complexity of the human brain and the uncertainty of neural mechanisms.To improve the reliability and objectivity of sleep spindle detection and to compensate for the limitations of manual annotation,this study proposes a new automatic detection algorithm based on Matching Pursuit(MP)and Least Squares Boosting(LSBoost),where the automatic sleep spindle detection algorithm can help reduce the visual annotation workload of sleep clinicians.Specifically,MP is a time-frequency analysis method suitable for extracting spindle wave characteristics,which can accurately locate spindle waves on a time-frequency plane.LSBoost is an ensemble learning classification method to deal with unbalanced data.Initially,theMP method is used to search for EEG segments that are possible spindle waves from the filtered raw EEG data.Then,the designed feature segments are thrown into the LSBoost classifier to further identify the real spindles from all candidates and output the final results.The proposed method is verified on the common public dataset DREAMS.The experiment results showthat the sensitivity and F1-scores based on the sample-based assessments achieve 68.2% and 55.4%,respectively.Furthermore,the Recall and F1-score based on the event assessments are 83.8% and 70.8%,respectively.These results show that the proposed algorithm is robust to the subject changes in the DREAMS dataset.In addition,it improves the quality of sleep spindle detection,which is expected to assist the manual marking of experts. | Fei Wang Li Li Yinxing Wan Zhuorong Li Lixian Luo Bangshun Hu Jiahui Pan Zhenfu Wen Haiyun Huang | 2023 | Computers, Materials & Continua2023，76，8： | 0 |
| 6 | Guanine-assisted N-doped ordered mesoporous carbons as efficient capacity decaying suppression materials for lithium–sulfur batteries显示文摘Lithium–sulfur(Li–S)batteries are considered promising next-generation energy storage devices due to their high weight capacities and theoretical energy densities,which are significantly higher than those of conventional lithium-ion batteries.However,the sulfur cathode presents two major drawbacks,specifically low specific capacity caused by the poor electrical conductivities of the active materials and fast capacity decay caused by polysulfide dissolution/shuttling.Herein,a high-rate and high-stability dendritic material consisting of N-doped ordered mesoporous carbons(NOMCs)was successfully synthesized via a facile and low-cost calcination method.The highly ordered mesoporous carbon skeleton limited the growth of the sulfur nanofiller within its channels and provided the necessary electrical contact with the insulating sulfur.Furthermore,N-doped heteroatoms presented strong binding sites for trapping polysulfide intermediates,achieving high electrochemical activity,which promoted polysulfide conversion reactions.As a result,the prepared NOMC-2/S cathode material with 1.2-1.5 mg cm^(-2)of sulfur displayed excellent electrochemical performance with a high-rate capability of 460.5 m Ah g^(-1)at 1 C,a high specific capacity of 530.9 m Ah g^(-1)after 200 cycles at 0.1 C,and a decay rate of~0.19%per cycle. | Riguang Cheng Yanxun Guan Yumei Luo Chenchen Zhang Yongpeng Xia Sheng Wei Mengmeng Zhao Qi Lin Hao Li Shiyou Zheng Federico Rosei Lixian Sun Fen Xu Hongge Pan | 2022 | Journal of Materials Science & Technology2022，，6： | 0 |
| 7 | A novel method for objectively, rapidly and accurately evaluating burn depth via near infrared spectroscopy显示文摘The accurate and objective evaluation of burn depth is a significant challenge in burn wound care.Herein,we used near infrared spectroscopy(NIRS)technology to measure the different depth of thermal burns in ex vivo porcine models.Based on the intensity of the spectral signals and the diffuse reflection theory,we extracted the optical parameters involved in functional(total hemoglobin andwater content)and structural(tissue scattered size and scattered particles)features that reflect the changes in burn depth.Next,we applied support vector regression to construct a model including the optical property parameters and the burn depth.Finally,we histologically verified the burn depth data collected via NIRS.The results showed that our inversion model could achieve an average relative error of about 7.63%,while the NIRS technology diagnostic accuracy was in the range of 50μm.For the first time,this novel technique provides physicians with real-time burn depth information objectively and accurately. | Meifang Yin Yongming Li Yongquan Luo Mingzhou Yuan Ubaldo Armato Ilaria Dal Prà Lijun Zhang Dayong Zhang Yating Wei Guang Yang Lixian Huang Pin Wang Jun Wu | 2021 | Burns & Trauma2021，9，1： | 0 |
