| 1 | Peroxymonosulfate assisted mechanochemical method for the degradation of phenanthrene in contaminated soils显示文摘In recent years,mechanochemical method has received attention in the field of degrading pollutants,especially for persistent organic pollutants.In this study,peroxymonosulfate(PMS)as a co-grinding reagent,coupled with contaminated soil were placed in a ball mill for mechanochemical reaction.Through investigating the influences of ball-milling parameters on the degradation efficiency,the reaction conditions were optimized.Under the optimal condition(mass ratio of soil to oxidant is 10:1,mass ratio of ball to material is 30:1,rotation speed of ball mill is 400 rpm),more than 98%phenanthrene(PHE)in contaminated soil could be degraded within 4 h.Meanwhile,the effects of soil organic matter content and soil type on the degradation efficiency were investigated.The results showed that the organic matter content was negatively correlated with the degradation efficiency.XPS analysis provided evidence for the breakage of the CeC bond and confirmed that Fe in soil was an important factor in activating PMS.XRD further verified the destruction of PHE structure.GC-MS analysis was performed to identify the intermediates and possible pathways were proposed. | Guoxuan Fan Xitao Liu Chunye Lin Peizhong Li | 2018 | Emerging Contaminants2018，4，1： | 4 |
| 2 | Paleogene marine deposition records of rifting and breakup of the South China Sea:An overview显示文摘A compilation of available marine deposition data from offshore S-SE China reveals evidence of rifting and breakup of the South China Sea(SCS) during the Paleogene. Marine deposition started earlier in the Paleocene in the East China Sea(ECS)-Taiwan region before expanding southwestward into the SCS region in the middle Eocene. Our data indicate the existence of an elongated Paleogene China Sea in these areas stretching along the northeasterly structural belts, probably as part of the marginal western paleo-Pacific. The southwestward shift of marine influence in the middle Eocene was responding to a period of intensive rifting and subsidence in the SCS region, while the sea in the ECS-Taiwan region started to shrink and shoal after the late Eocene, likely associated with local breakup and initial spreading in the Taiwan-Taixinan Basin area. The accumulation of hemipelagic sediments at ODP 1148 and IODP U1435 from near the continent-ocean boundary and at many other shelf-slope sites was in response to a large-scale breakup 34 to 33 Ma ago, subsequently leading to the birth of the SCS in the Oligocene. | LI QianYu WU GuoXuan ZHANG LiLi SHU Yu SHAO Lei | 2017 | Science China Earth Sciences2017，60，12： | 3 |
| 3 | Effect of rich R-TiO2 on the rate and cycle properties of Li4Ti5O12 as anode for lithium ion batteries显示文摘Li4Ti5012 (LTO) with rich R-TiO2 (17.06, 23.69, and 34.42 wt%), namely, R-TiO2@Li4Ti5O12 composites, were synthesized using the hydrothermal method and tetrabutyl titanate (TBT) as the precursor. Rietveld refinement of X-ray diffraction (XRD) results show that the proportion of Li occupying 16d sites is extraordinary low and the lattice constants of LTO and R-TiO2 change with the ritanium dioxide content. EIS measurements showed that with in creasing R-TiO2 content, both its charge transfer impedance (Rct) and lithium ion diffusion coefficient (DLi) decreased. The changes of Rct and DLi caused by the increase of titanium dioxide content have synergic-antagonistic effects on the rate and cycle properties of Li4Ti5012. The rate performance is positively related to DLi, while the cycle property is negatively correlated with Rct, indicati ng that the rate performs nee is mainly related to DLi, while Rct more significantly affects the cycle performance. LTO-RT-17.06% exhibited excellent rate properties, especially under a high current density (5.0 C, 132.5 mAh/g) and LTO-RT-34.42% showed superior long-term cycle performance (0.012% capacity loss per cycle) compared to that of LTO-RT-17.06% and LTO-RT-23.69%. | Delai Qian Yijie Gu Shuainan Guo Hongquan Liu Yunbo Chen Juan Wang Guoxuan Ma Chuan Wu | 2019 | Journal of Energy Chemistry2019，28，5： | 3 |
| 4 | Palynomorphs in the first paleosol layer in the Yangtze Delta and their paleoenvi-ronmental implication显示文摘The relatively abundant palynomorphs were recovered from the samples of the first paleosol layer of core CY in Shanghai for the first time. A total of 55 genera and families of spore, pollen and phytoplankton were identified. According to the characteristics of the palynological assemblages, the depositional conditions in the development period of the paleosols were discussed and the microfossil evidence to study the origin of the paleosols in the Yangtze Delta area was provided as well. The research results show that paleosols should be freshwater deposits. The palynological assemblage sequence in the first paleosol layer reveals fluctuations of freshwater palynomorphs, mainly Concentricystis, and terricolous herbs pollen, reflecting the alternations of deposition and exposure in the development period of the paleosols. Concentricystis developed prosperously in the period of flood, while terricolous herbs grew on the emerged land in the period of exposure.

| 6 | Determination of a suitable index for a solvent via two-column extractive distillation using a heuristic method显示文摘The traditional approach to solvent selction in the extractive distillation process strictly focuses on the change in the relative voltility of light-heavy components induced by the solvent.However,the total annual cost of the process may not be minimal when the solvent induces the largest change in relative volatility.This work presents a heuristic method for selecting the optimal solvent to minimize the total annual cost.The functional relationship between the relative volatility and the total annual cost is established,where the main factors,such as the relative volatility of the light-heavy components and the relative volatility of the heavy-component solvent,are taken into account.Binary azeotropic mixtures of methanol-toluene and methanol-acetone are separated to verify the feasibility of the model.The results show that using the solvent with the minimal two-column extractive distillation index,the process achieves a minimal total annual cost.The method is conducive for sustainable advancements in chemistry and engineering because a suitable solvent can be selected without simulation verification. | Zhaoyou Zhu Guoxuan Li Yao Dai Peizhe Cui Dongmei Xu Yinglong Wang | 2020 | Frontiers of Chemical Science and Engineering2020，14，5： | 2 |

| 12 | Miniaturized structured illumination microscopy with diffractive optics显示文摘Structured illumination microscopy(SIM)is an advanced microscope system that provides superresolution capability with excellent imaging speed,which has become a practical tool for live-cell imaging.However,the bulky size is blocking the application of SIM in wider study fields and scenarios.Here,we developed a miniaturized SIM(Mini SIM)system that provided periodic illumination using a diffractive optical element(DOE)for the first time.This optimized phase-only DOE generated the two-dimensional sinusoidal illumination by optical Fourier transform with an illuminating objective lens,which substantially simplified and miniaturized the illumination system.We built up a Mini SIM prototype and demonstrated lateral superresolution imaging of fluorescence beads and A549 cell slides.The proposed Mini SIM greatly simplifies the experimental setup and may lead to important applications in bio-imaging. | GUOXUAN LIU NING XU HUAIDONG YANG QIAOFENG TAN GUOFAN JIN | 2022 | Photonics Research2022，10，5： | 1 |

| 15 | Nucleation and growth control for iron-and phosphorus-rich phases from a modified steelmaking waste slag显示文摘Recovering the iron(Fe)and phosphorus(P)contained in steelmaking slags not only reduces the environmental burden caused by the accumulated slag,but also is the way to develop a circular economy and achieve sustainable development in the steel industry.We had pre-viously found the possibility of recovering Fe and P resources,i.e.,magnetite(Fe_(3)O_(4)) and calcium phosphate(Ca_(10)P_(6)O_(25)),contained in steel-making slags by adjusting oxygen partial pressure and adding modifier B_(2)O_(3).As a fundamental study for efficiently recovering Fe and P from steelmaking slag,in this study,the crystallization behavior of the CaO-SiO_(2)-FeO-P_(2)O_(5)-B_(2)O_(3) melt has been observed in situ,using a confocal scanning laser microscope(CLSM).The kinetics of nucleation and growth of Fe-and P-rich phases have been calculated using a classical crys-tallization kinetic theory.During cooling,a Fe_(3)O_(4) phase with faceted morphology was observed as the 1st precipitated phase in the isothermal interval of 1300-1150℃,while Ca_(10)P_(6)O_(25),with rod-shaped morphology,was found to be the 2nd phase to precipitate in the interval of 1150-1000℃.The crystallization abilities of Fe_(3)O_(4) and Ca_(10)P_(6)O_(25) phases in the CaO-SiO_(2)-FeO-P_(2)O_(5)-B_(2)O_(3) melt were quantified with the in-dex of(T_(U)−T_(I))/T_(I)(where T_(I) represents the peak temperature of the nucleation rate and TU stands for that of growth rate),and the crystalliza-tion ability of Fe_(3)O_(4) was found to be larger than that of Ca_(10)P_(6)O_(25) phase.The range of crystallization temperature for Fe_(3)O_(4) and Ca_(10)P_(6)O_(25) phases was optimized subsequently.The Fe_(3)O_(4) and Ca_(10)P_(6)O_(25) phases are the potential sources for ferrous feedstock and phosphate fertilizer,respectively. | Juncheng Li Guoxuan Li Feng Qiu Rong Wang Jinshan Liang Yi Zhong Dong Guan Jingwei Li Seetharaman Sridhar Zushu Li | 2023 | International Journal of Minerals,Metallurgy and Materials2023，30，2： | 0 |
| 16 | Ultrasonic Barker-coded excitation method with attenuation matching显示文摘In order to increase the ability of ultrasound to penetrate high-attenuation medium,an attenuation matching method of ultrasonic Barker-coded excitation is proposed.The signal model of Barker-coded excitation is obtained based on assumptions of transducer impulse response with Gaussian shape and linear phase attenuation without dispersion in the material.By solving the expression of signal-to-noise ratio of Barker-coded pulse compression after sidelobe suppression,it can be seen that the proposed method only needs to adjust the center frequency and time duration of the Barker-coded signal according to the material attenuation and the requirement of axial resolution.Take the rubber with an attenuation coefficient of 1.4 Np/(MHz-cm)and a thickness of 5 cm for example,with a similar axial resolution,the signal-to-noise ratio gain of attenuation matching Barker-coded excitation method is approximately 5 dB higher than that of traditional Barker-coded excitation method.Furthermore,the increase of the signal-to-noise ratio gain grows to 11 dB at the cost of the axial resolution.The results show that the attenuation matching Barker-coded excitation method can reduce the influence of frequency-dependent attenuation on pulse compression and can effectively improve the signal-to-noise ratio of the attenuated echo. | WANG Qiang MAO Jie DING Xiaodong LIAN Guoxuan HU Yu’an | 2021 | Chinese Journal of Acoustics2021，40，3： | 0 |
| 17 | Propagation of guided waves in a bonded plate:Antiplane shear modes显示文摘The displacement and stress as well as the dispersion equation for the guided waves of antiplane shear (SH) modes in a bonded plate are presented explicitly. The spring model is used to account for the interface rigidity between the layers of the bonded plate. It is found that the dispersion equation is composed of the terms pertinent with the welded and the cracked or slip boundary conditions with the compliance sT of the spring model as the sum-coefficients. Numerical results for an adhesive plate of aluminum and steel whose wave velocities are very close to each other of equal thickness indicate that the modes of odd order are more sensitive than the even ones to the variations of the bond quality, and so are the higher modes than the lower ones for this special layered plate. The phenomena of the cut-off frequency-shift and the phase velocity decrease resulting from the degradation of the bond quality are found to the modes of odd order, which may be used to evaluate the bond states of the adhesive plate. Numerical results for an adhesive plate of rubber and steel whose wave velocities are very different to each other of equal thickness are presented and discussed as well. | WANG Xiaomin, LIAN Guoxuan, LI Mingxuan (Institute of Acoustics, Academia Sinica Beijing 100080) | 2001 | Chinese Journal of Acoustics2001，20，2： | 0 |
| 18 | A Frequency Tunable Liquid Cavity Bandpass Filter显示文摘A liquid-loaded frequency tunable cavity bandpass filter (BPF) is presented. A dielectric fluidic material, dimethyl silicone oil (DSO) withexcellent thermophysical characteristics (working temperature from −50 ℃ to 180 ℃) and extremely low loss tangent is employed as a dielectric loading.The frequency reconfigurability of the proposed design is realized by altering the liquid level inside the cavity resonator. The filter achieves a widefrequency tuning range as well as a high Q factor. Moreover, this design shows significantly improved environmental suitability in extreme temperaturecases, outperforming the existing microfluidic-based RF devices using water or liquid metals. A four-pole tunable cavity bandpass filter is designed andverified. A cross-coupling structure comprising a metal loop structure is used to introduce transmission zeros in the proposed filter, which enhances theskirt selectivity and out-of-band rejections. We demonstrate that the center frequency of the proposed BPF can be tuned from 4.92 GHz to 6.16 GHz,and the filter achieves a high Q factor between 521 and 1527. The measured results agree well with simulated results. | Guoxuan Zhang Lei Xing Qian Xu Yongjiu Zhao Chaoyun Song Yi Huang | 2023 | Electromagnetic Science2023，1，2： | 0 |
| 19 | Reliability Assessment of a New General Matching Composed Network显示文摘The reliability of a network is an important indicator for maintaining communication and ensuring its stable operation. Therefore, the assessment of reliability in underlying interconnection networks has become an increasingly important research issue. However, at present, the reliability assessment of many interconnected networks is not yet accurate,which inevitably weakens their fault tolerance and diagnostic capabilities. To improve network reliability,researchers have proposed various methods and strategies for precise assessment. This paper introduces a novel family of interconnection networks called general matching composed networks(gMCNs), which is based on the common characteristics of network topology structure. After analyzing the topological properties of gMCNs, we establish a relationship between super connectivity and conditional diagnosability of gMCNs. Furthermore, we assess the reliability of g MCNs, and determine the conditional diagnosability of many interconnection networks. | Zhengyuan Liang Junbin Liang Guoxuan Zhong | 2024 | China Communications2024，21，2： | 0 |
| 20 | On the validity of microscopic calculations of double-quantum-dot spin qubits based on Fock-Darwin states显示文摘We consider two typical approximations that are used in the microscopic calculations of double-quantum dot spin qubits, namely,the Heitler-London(HL) and the Hund-Mulliken(HM) approximations, which use linear combinations of Fock-Darwin states to approximate the two-electron states under the double-well confinement potential. We compared these results to a case in which the solution to a one-dimensional Schr ¨odinger equation was exactly known and found that typical microscopic calculations based on Fock-Darwin states substantially underestimate the value of the exchange interaction, which is the key parameter that controls the quantum dot spin qubits. This underestimation originates from the lack of tunneling of Fock-Darwin states, which is accurate only in the case with a single potential well. Our results suggest that the accuracies of the current two-dimensional molecularorbit-theoretical calculations based on Fock-Darwin states should be revisited since underestimation could only deteriorate in dimensions that are higher than one. | GuoXuan Chan Xin Wang | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，4： | 0 |
