| 1 | Determination of full-scale pore size distribution of Gaomiaozi bentonite and its permeability prediction显示文摘Gaomiaozi(GMZ)bentonite is a potential buffer/backfill material for a deep geological disposal of highlevel radioactive waste.It has a wide pore size distribution(PSD)with sizes ranging from several nanometers to more than one hundred microns.Thus,properly characterizing the pore structures of GMZ bentonite is a challenging issue.In this study,pressure-controlled porosimetry(PCP),ratecontrolled porosimetry(RCP),and scanning electron microscopy(SEM)were used to investigate the PSD of GMZ bentonite,The results indicate that each method has its limitation,and a combined use of PCP and RCP is suitable to obtain the full-scale PSD of GMZ bentonite.Moreover,we also compared the full-scale PSD with nuclear magnetic resonance(NMR)result.It is found that there is no significant difference in the range of PSD characterization between NMR and mercury intrusion method(PCP and RCP).However,in a ce rtain range,the detection accuracy of NMR is higher than that of mercury injection method.Finally,permeability prediction based on PCP and SEM data was conducted,and both of the two methods were found to be able to predict the permeability.The combined method is effective to obtain the full-scale PSD of GMZ bentonite,which is the key to estimation of the sealing ability of bentonite buffer. | Jiangfeng Liu Shuaibing Song Xulou Cao Qingbin Meng Hai Pu Yangguang Wang Jianfeng Liu | 2020 | Journal of Rock Mechanics and Geotechnical Engineering2020，12，2： | 5 |

| 3 | A simple method for determining independent fracture toughness and tensile strength of rock显示文摘This paper develops a model that only requires two sets of small-size rock specimens with the ratio of the structural geometry parameter maximum to minimum ae,max:ae,min≥3:1 to determine the rock fracture and strength parameters without size effect and predict the actual structural performance of rock.Regardless of three-point-bending,four-point-bending,or a combination of the above two specimen types,fracture toughness KICand tensile strength ftof rock were determined using only two sets of specimens with ae,max:ae,min≥3:1.The values KICand ftwere consistent with those determined using multiple sets of specimens.The full structural failure curve constructed by two sets of small-size specimens with ae,max:ae,min≥3:1 can accurately predict large-size specimens fracture failure,and±10%upper and lower limits of the curve can encompass the test results of large-size specimens.The peak load prediction curve was constructed by two sets of specimens with ae,max:ae,min≥3:1,and±15%upper and lower limits of the peak load prediction curve can cover the small-size specimen tests data.The model and method proposed in this paper require only two sets of small-size specimens,and their selection is unaffected by the specimen type,geometry,and initial crack length. | Junfeng Guan Yulong Zhang Jiangfeng Meng Xianhua Yao Lielie Li Shuanghua He | 2022 | International Journal of Mining Science and Technology2022，32，4： | 1 |

| 5 | Quantum metrology with single spins in diamond under ambient conditions显示文摘The detection of single quantum systems can reveal information that would be averaged out in traditional techniques based on ensemble measurements. The nitrogen-vacancy(NV) centers in diamond have shown brilliant prospects of performance as quantum bits and atomic sensors under ambient conditions, such as ultra-long coherence time, high fidelity control and readout of the spin state. In particular, the sensitivity of the NV center spin levels to external environmental changes makes it a versatile detector capable of measuring various physical quantities, such as temperature, strain, electric fields and magnetic fields. In this paper, we review recent progress in NV-based quantum metrology, and speculate on its future. | ming chen chao meng qi zhang changkui duan fazhan shi jiangfeng du | 2018 | National Science Review2018，5，3： | 1 |
| 6 | Identification of Age-associated Proteins and Functional Alterations in Human Retinal Pigment Epithelium显示文摘Retinal pigment epithelium(RPE)has essential functions,such as nourishing and supporting the neural retina,and is of vital importance in the pathogenesis of age-related retinal degeneration.However,the exact molecular changes of RPE during aging remain poorly understood.Here,we isolated human primary RPE(h RPE)cells from 18 eye donors distributed over a wide age range(10–67 years old).A quantitative proteomic analysis was performed to analyze changes in their intracellular and secreted proteins.Age-group related subtypes and age-associated proteins were revealed and potential age-associated mechanisms were validated in ARPE-19 and h RPE cells.The results of proteomic data analysis and verifications suggest that RNF123-and RNF149-related protein ubiquitination plays an important role in protecting h RPE cells from oxidative damage during aging.In older h RPE cells,apoptotic signaling-related pathways were up-regulated,and endoplasmic reticulum organization was down-regulated both in the intracellular and secreted proteomes.Our work paints a detailed molecular picture of h RPE cells during the aging process and provides new insights into the molecular characteristics of RPE during aging and under other related clinical retinal conditions. | Xiuxiu Jin Jingyang Liu Weiping Wang Jiangfeng Li Guangming Liu Ruiqi Qiu Mingzhu Yang Meng Liu Lin Yang Xiaofeng Du Bo Lei | 2022 | Genomics, Proteomics & Bioinformatics2022，20，4： | 0 |
| 7 | Jahn-Teller Effect Directed Bandgap Tuning of Birnessite for Pseudocapacitive Application显示文摘Birnessite M_(x)MnO_(2)(M=Na^(+),K^(+),etc.)has emerged as a promising alternative to the classical MnO_(2)material owing to its improved pseudocapacitive performance for energy storage.Understanding their structure–property correlation is essential for the development and application of advanced supercapacitors.Herein,we adopt the crystal field theory and density functional simulation to reveal the structural dependence of the pseudocapacitive property of M_(x)MnO_(2).Attributing to the Jahn–Teller effect of Mn^(3+),the bandgap of Kx MnO_(2)can be tuned by changing the x value(i.e.,the Mn(III)/Mn(IV)ratio).Then,we design a narrow-bandgap K 0.25 MnO_(2)(0.84 eV),which affords a high capacitance of 415 F g^(-1)at 1 A g^(-1)and a desirable rate capability of 293 F g^(-1)at 20 A g^(-1).Operando Raman spectroscopy confirms that the Jahn–Teller induced structure evolution of[MnO_(6)]octahedron accounts for the superior pseudocapacitive behavior of K_(0.25)MnO_(2).This finding offers theoretical guidance to the design and application of birnessite materials for pseudocapacitors. | Sheng Zhu Yuechao Wang Jinshu Zhang Jian Sheng Feng Yang Meng Wang Jiangfeng Ni Hong Jiang Yan Li | 2023 | Energy & Environmental Materials2023，6，3： | 0 |
| 8 | An Approximate Analytical Method for a Slot Ring Radome显示文摘In this paper,an in-band and out-of-band microwave wireless power-transmission characteristic analysis of a slot ring radome based on an approximate analytical method is proposed.The main contribution of this paper is that,in the approximate analysis of the ring radome,a unified expression of the incident field on the radome surface is derived with E-plane and H-plane scanning,and the ring is approximated as 30 segments of straight strips.Solving the corresponding 60×60 linear equations yields the electric current distribution along the ring strip.The magnetic current along the complementary slot ring is obtained by duality.Thanks to the fully analytical format of the current distribution,the microwave wireless power-transmission characteristics are efficiently calculated using Munk’s scheme.An example of a slot ring biplanar symmetric hybrid radome is used to verify the accuracy and efficiency of the proposed scheme.The central processing unit(CPU)time is about 690 s using Ansys HFSS software versus 2.82 s for the proposed method. | Kang Luo Jin Meng Jiangfeng Han Danni Zhu | 2023 | Engineering2023，，11： | 0 |
| 9 | Digitally programmable organic light‐emitting tetrodes显示文摘Limited to the structure of traditional light‐emitting devices,electronic devices that can directly convert machine language into human visual information without introducing any back‐end circuit are still not easy to achieve.Based on a specially designed three‐phase co‐planar electrode structure,a new type of three‐phase alternating current driven organic light‐emitting device with the integration of emission and control functions,full‐color tunability and simple device structure is demonstrated in this study.We integrate the light‐emitting function of color‐tunable light‐emitting devices and the switching of three triodes in a single three phase organic light‐emitting device.The state control of luminous color and luminance intensity merely requires the introduction of a kind of machine language,that is an easy‐to‐program 6‐bit binary number coded digital signals.The color adjustable area covers 66%of the color triangle of the National Television System Committee.Such simple and easy‐to‐integrate light‐emitting system has great potential applications in the next‐generation man‐machine interface. | Junpeng Ji Biao Yang Chaohong Zhang Yulu Cai Jingwei Chen Changbin Zhao Tao Wang Lijie Wu Ming Liu Junwu Bai Jiangfeng Wang Zhongbin Wu Shufen Chen Haifeng Ling Zhongfu An Yonghua Chen Jianpu Wang Wei Huang Hong Meng | 2023 | SmartMat2023，4，2： | 0 |
