| 1 | Degradation of bisphenol-A using ultrasonic irradiation assisted by low-concentration hydrogen peroxide显示文摘This study investigated the degradation of bisphenol-A (BPA) by ultrasonic irradiation in the presence of different additives (H2O2,air bubbles and humic acid) under various operating conditions,i.e.,ultrasonic frequency,power intensity and power density.The results demonstrated that the BPA degradation followed pseudo first-order kinetics under different experimental conditions.The optimum power intensities were 0.9,1.8,and 3.0W/cm 2 at the frequencies of 400,670,and 800 kHz,respectively.At the fixed frequency (800 kHz),the degradation rate of BPA was shown proportional to the increase of power density applied.With this manner,the BPA sonolysis could be facilitated at H2O2 dosage being lower than 0.1 mmol/L;while BPA degradation was hindered at H2O2 concentration in excess of 1 mmol/L.Additionally,BPA removal was shown to be inhibited by the presence of aeration and humic acid during ultrasonic irradiation.The present study suggested that the degradation rate of BPA assisted by ultrasonic irradiation was influenced by a variety of factors,and high BPA removal rate could be achieved under appropriate conditions. | Kejia Zhang Naiyun Gao Yang Deng Tsair Fuh Lin Yan Ma Lei Li Minghao Sui | 2011 | Journal of Environmental Sciences2011，23，1： | 9 |

| 3 | The Gravitational-wave physics Ⅱ: Progress显示文摘It has been a half-decade since the first direct detection of gravitational waves, which signifies the coming of the era of the gravitational-wave astronomy and gravitational-wave cosmology. The increasing number of the detected gravitational-wave events has revealed the promising capability of constraining various aspects of cosmology, astronomy, and gravity. Due to the limited space in this review article, we will briefly summarize the recent progress over the past five years, but with a special focus on some of our own work for the Key Project 'Physics associated with the gravitational waves' supported by the National Natural Science Foundation of China. In particular,(1) we have presented the mechanism of the gravitational-wave production during some physical processes of the early Universe, such as inflation, preheating and phase transition, and the cosmological implications of gravitational-wave measurements;(2) we have put constraints on the neutron star maximum mass according to GW170817 observations;(3) we have developed a numerical relativity algorithm based on the finite element method and a waveform model for the binary black hole coalescence along an eccentric orbit. | Ligong Bian Rong-Gen Cai Shuo Cao Zhoujian Cao He Gao Zong-Kuan Guo Kejia Lee Di Li Jing Liu Youjun Lu Shi Pi Jian-Min Wang Shao-Jiang Wang Yan Wang Tao Yang Xing-Yu Yang Shenghua Yu Xin Zhang | 2021 | Science China(Physics,Mechanics & Astronomy)2021，64，12： | 2 |

| 5 | Influence of the amplitude ratio between two terahertz pulses on two-dimensional spectroscopy显示文摘The influence of the amplitude ratio between the two THz pulses on two-dimension THz spectroscopy(2DTS)has been studied theoretically via a classical method in which the expressions for the second-order nonlinearity were derived using perturbation approach,and the THz pulses were not treated as a delta function.Three types of nonlinear sources i.e.,anharmonicity,nonlinear damping,and nonlinear coupling,are considered in a single mode system.The simulation results demonstrated that the amplitude ratio had a notable influence on the 2DTSs,and different sources have different influences.This study is promising for guiding future experiments. | Jiangsheng Hu Jinsong Liu Huquan Li Kejia Wang Zhengang Yang Shenglie Wang | 2014 | Chinese Science Bulletin2014，59，2： | 1 |

| 11 | Fe65-engineered neuronal exosomes encapsulating corynoxine-B ameliorate cognition and pathology of Alzheimer’s disease显示文摘Alzheimer’s disease(AD)is a neurodegenerative disorder characterized by the predominant impairment of neurons in the hippocampus and the formation of amyloid plaques,hyperphosphorylated tau protein,and neurofibrillary tangles in the brain.The overexpression of amyloid-βprecursor protein(APP)in an AD brain results in the binding of APP intracellular domain(AICD)to Fe65 protein via the C-terminal Fe65-PTB2 interaction,which then triggers the secretion of amyloid-βand the consequent pathogenesis of AD.Apparently,targeting the interaction between APP and Fe65 can offer a promising therapeutic approach for AD.Recently,exosome,a type of extracellular vesicle with diameter around 30–200 nm,has gained much attention as a potential delivery tool for brain diseases,including AD,due to their ability to cross the blood–brain barrier,their efficient uptake by autologous cells,and their ability to be surface-modified with target-specific receptor ligands.Here,the engineering of hippocampus neuron cell-derived exosomes to overexpress Fe65,enabled the development of a novel exosome-based targeted drug delivery system,which carried Corynoxine-B(Cory-B,an autophagy inducer)to the APP overexpressed-neuron cells in the brain of AD mice.The Fe65-engineered HT22 hippocampus neuron cell-derived exosomes(Fe65-EXO)loaded with Cory-B(Fe65-EXO-Cory-B)hijacked the signaling and blocked the natural interaction between Fe65 and APP,enabling APP-targeted delivery of Cory-B.Notably,Fe65-EXO-Cory-B induced autophagy in APP-expressing neuronal cells,leading to amelioration of the cognitive decline and pathogenesis in AD mice,demonstrating the potential of Fe65-EXO-Cory-B as an effective therapeutic intervention for AD. | Ashok Iyaswamy Abhimanyu Thakur Xin-Jie Guan Senthilkumar Krishnamoorthi Tsz Yan Fung Kejia Lu Isha Gaurav Zhijun Yang Cheng-Fu Su Kwok-Fai Lau Kui Zhang Roy Chun-Laam Ng Qizhou Lian King-Ho Cheung Keqiang Ye Huanhuan Joyce Chen Min Li | 2023 | Signal Transduction and Targeted Therapy2023，8，11： | 0 |
| 12 | Excess mortality associated with high ozone exposure:A national cohort study in China显示文摘Emerging epidemiological studies suggest that long-term ozone(O_(3))exposure may increase the risk of mortality,while pre-existing evidence is mixed and has been generated predominantly in North America and Europe.In this study,we investigated the impact of long-term O_(3)exposure on all-cause mortality in a national cohort in China.A dynamic cohort of 20882 participants aged40 years was recruited between 2011 and 2018 from four waves of the China Health and Retirement Longitudinal Study.A Cox proportional hazard regression model with time-varying exposures on an annual scale was used to estimate the mortality risk associated with warm-season(Aprile September)O_(3)exposure.The annual average level of participant exposure to warm-season O_(3)concentrations was 100 mg m^(-3)(range:61 e142 mg m^(-3)).An increase of 10 mg m^(-3)in O_(3)was associated with a hazard ratio(HR)of 1.18(95%confidence interval[CI]:1.13e1.23)for all-cause mortality.Compared with the first exposure quartile of O_(3),HRs of mortality associated with the second,third,and highest exposure quartiles were 1.09(95%CI:0.95e1.25),1.02(95%CI:0.88e1.19),and 1.56(95%CI:1.34e1.82),respectively.A J-shaped concentration eresponse associationwas observed,revealing a non-significant increase in risk below a concentration of approximately 110 mg m^(-3).Low-temperature-exposure residents had a higher risk of mortality associated with long-term O_(3)exposure.This study expands current epidemiological evidence from China and reveals that high-concentration O_(3)exposure curtails the long-term survival of middle-aged and older adults. | Yang Yuan Kai Wang Haitong Zhe Sun Yu Zhan Zhiming Yang Kejia Hu Yunquan Zhang | 2023 | Environmental Science and Ecotechnology2023，，3： | 0 |
| 13 | Level pinning of anti-PT-symmetric circuits for efficient wireless power transfer显示文摘Wireless power transfer(WPT) technology based on magnetic resonance(a basic physical phenomenon)can directly transfer energy from the source to the load without wires and other physical contacts, and has been successfully applied to implantable medical devices, electric vehicles, robotic arms and other fields.However, due to the frequency splitting of near-field coupling, the resonant WPT system has some unique limitations, such as poor transmission stability and low efficiency. Here, we propose anti-resonance with level pinning for high-performance WPT. By introducing the anti-resonance mode into the basic WPT platform, we uncover the competition between dissipative coupling and coherent coupling to achieve novel level pinning, and construct an effective anti-parity-time(anti-PT)-symmetric non-Hermitian system that is superior to previous PT-symmetric WPT schemes. On the one hand, the eigenvalue of the anti-PT-symmetric system at resonance frequency is always pure real in both strong and weak coupling regions, and can be used to overcome the transmission efficiency decrease caused by weak coupling, as brought about by, for example, a large size ratio of the transmitter to receiver, or a long transmission distance.On the other hand, due to the level pinning effect of the two kinds of coupling mechanisms, the working frequency of the system is guaranteed to be locked, so frequency tracking is not required when the position and size of the receiver change. Even if the system deviates from the matching condition, an efficient WPT can be realized, thereby demonstrating the robustness of the level pinning. The experimental results show that when the size ratio of the transmitter coil to the receiver coil is 4.29(which is in the weak coupling region), the transfer efficiency of the anti-PT-symmetric system is nearly 4.3(3.2) times higher than that of the PT-symmetric system when the matching conditions are satisfied(deviated). With the miniaturization and integration of devices in mind, a synthetic anti-PT-symmetric system is used to realize a robust WPT.Anti-PT-symmetric WPT technology based on the synthetic dimension not only provides a good research platform for the study of abundant non-Hermitian physics, but also provides a means of going beyond traditional near-field applications with resonance mechanisms, such as resonance imaging, wireless sensing and photonic routing. | Zhiwei Guo Fengqing Yang Haiyan Zhang Xian Wu Qiong Wu Kejia Zhu Jun Jiang Haitao Jiang Yaping Yang Yunhui Li Hong Chen | 2024 | National Science Review2024，11，1： | 0 |

| 16 | Anti-melanoma effect and action mechanism of a novel chitosan-based composite hydrogel containing hydroxyapatite nanoparticles显示文摘Hydroxyapatite nanoparticles(HANPs)have been increasingly regarded and reported due to their potential anti-tumor ability.Previously,we found that the rod-like HANPs had good application potential for cutaneous melanoma(CMM).To satisfy the actual requirements in repairing post-operative skin defects and inhibiting CMM recurrence after tumorectomy,we constructed a novel chitosan/alginate(CS/Alg)hydrogel containing the aforementioned HANPs.The in vitro cell experiments confirmed that activated mitochondrial-dependent apoptosis was tightly related to the anti-tumor ability of HANPs.Specifically,we further discovered several target proteins might be involved in abnormal activating Wnt,proteoglycans in cancer,oxidative phosphorylation and p53 signaling pathways.The in vivo animal experiments demonstrated that the HANPsloaded CS/Alg hydrogel(CS/Alg/HANPs)had a similar effect on inhibiting tumor growth as HANPs,and CS/Alg hydrogel as well as phosphate buffered saline(PBS)group(control)not showed any effect,proving the key role of HANPs.The immunohistochemical staining demonstrated a tumor inhibition via the mitochondria-mediated apoptosis pathway,consistent with the in vitro evaluation.Moreover,CS/Alg/HANPs exhibited no additional biosafety risk to the functions of major organs.Overall,this CS/Alg/HANPs hydrogel has substantial application potential for treating CMM. | Kejia Xu Yifu Wang Yao Xie Xiaoyan Zhang Wei Chen Zhongtao Li Tingting Wang Xiao Yang Bo Guo Lin Wang Xiangdong Zhu Xingdong Zhang | 2022 | Regenerative Biomaterials2022，9，1： | 0 |

| 19 | Grey clustering evaluation based on AHP and interval grey number显示文摘Purpose–The purpose of this paper is to propose a grey clustering evaluation model based on analytic hierarchy process(AHP)and interval grey number(IGN)to solve the clustering evaluation problem with IGNs.Design/methodology/approach–First,the centre-point triangular whitenisation weight function with real numbers is built,and then by using interval mean function,the whitenisation weight function is extended to IGNs.The weights of evaluation indexes are determined by AHP.Finally,this model is used to evaluate the flight safety of a Chinese airline.The results indicate that the model is effective and reasonable.Findings–When IGN meets certain conditions,the centre-point triangular whitenisation weight function based on IGN is not multiple-cross and it is normative.It provides a certain standard and basis for obtaining the effective evaluation indexes and determining the scientific evaluation of the grey class.Originality/value–The traditional grey clustering model is extended to the field of IGN.It can make full use of all the information of the IGN,so the result of the evaluation is more objective and reasonable,which provides supports for solving practical problems. | Kejia Chen Ping Chen Lixi Yang Lian Jin | 2019 | International Journal of Intelligent Computing and Cybernetics2019，12，1： | 0 |
