| 1 | Efficient and stable tin-based perovskite solar cells by introducing π-conjugated Lewis base显示文摘Tin-based perovskite solar cells(TPSCs)as the most promising candidate for lead-free PSCs have incurred extensive researches all over the world.However,the crystallization process of tin-based perovskite is too fast during the solution-deposited process,resulting in abundant pinholes and poor homogeneity that cause serious charge recombination in perovskite layer.Here,we employed theπ-conjugated Lewis base molecules with high electron density to systematically control the crystallization rate of FASnI3 perovskite by forming stable intermediate phase with the Sn-I frameworks,leading to a compact and uniform perovskite film with large increase in the carrier lifetime.Meanwhile,the introduction of theπ-conjugated systems also retards the permeation of moisture into perovskite crystal,which significantly suppresses the film degradation in air.These benefits contributed to a stabilizing power conversion efficiency(PCE)of 10.1%for the TPSCs and maintained over 90%of its initial PCE after 1000-h light soaking in air.Also,a steady-state efficiency of 9.2%was certified at the accredited test center. | Tianhao Wu Xiao Liu Xin He Yanbo Wang Xiangyue Meng Takeshi Noda Xudong Yang Liyuan Han | 2020 | Science China Chemistry2020，63，1： | 6 |

Xueshan Township,Luquan Yi and Miao Autonomous County of Yunnan Province,located in the alpine valley of Jinsha River,is a major township with wide and deep poverty,and the incidence of poverty is up to 45. 00%. In recent years,Xueshan Township has insisted on the battle against poverty,made effort to develop the Codonopsis pilosula industry,and successfully developed a road to poverty alleviation through C. pilosula industry,and formed a unique industrial poverty alleviation model by the end of 2018,the incidence of poverty dropped to 0. 74%. Based on field survey and interview,this paper analyzes and summarizes the specific practices,main results,practical experience and promotion and application measures of the poverty alleviation model of C. pilosula planting industry in Xueshan Township,in the hope of providing certain reference for the targeted poverty alleviation in similar areas in Yunnan Province and other provinces of China. | Zisheng YANG Renyi YANG Yanbo HE Chonghui LU En ZHU Yaohan PI Mingxin WU Ying XIONG | 2019 | Asian Agricultural Research2019，11，3： | 4 |
| 3 | Enhanced removal of bisphenol A by cyclodextrin in photocatalytic systems:Degradation intermediates and toxicity evaluation显示文摘At present,the assessment of photooxidation system mainly focuses on the photodegradation efficie ncy of target pollutant,lacking of the toxicity assessment in the photocatalysis process.Here,photodecomposition of bisphenol A(BPA)was used to investigate the performance of several cyclodextrin modified photocatalysts.Moreover,the comprehensive toxicity changes of BPA under different photocatalytic oxidation conditions were conducted.Theβ-cyclodextrin(β-CD)modified photocatalyst,including titanium dioxide(CM-β-CD-TiO_(2)),carbon nitride(CM-β-CD-C_(3)N_(4))and cadmium sulfide(SH-β-CD-AM/CdS)exhibit high degradation rate and mineralization efficiency of BPA.The highest total organic carbon(TOC)removal of BPA observed in the oxidation system of SH-β-CD-AM/CdS nano reactor(73.4%).The main oxidation intermediates in these systems were detected,and the comprehension toxicity of BPA and its oxidation intermediates in different system were compared by toxicity estimation software tool(T.E.S.T.)based on quantitative structure-activity relationship(QSAR)prediction.The results show thatβ-CD can facilitate the photodecomposition of the target contaminant.Howeve r,many oxidation intermediates with high compre hensive toxicity,eve n in the oxidation system with high B PA removal,can still be detected.Therefo re,not only decomposition of target contaminant but also the comprehensive toxicity of oxidation intermediates should be regarded as index to evaluate a photocatalysis technology. | Yi Zhou Jie He Jian Lu Yongdi Liu Yanbo Zhou | 2020 | Chinese Chemical Letters2020，31，10： | 3 |
| 4 | Study of Texture Segmentation and Classification for Grading Small Hepatocellular Carcinoma Based on CT Images显示文摘To grade Small Hepatocellular Car Cinoma(SHCC)using texture analysis of CT images,we retrospectively analysed 68 cases of Grade II(medium-differentiation)and 37 cases of Grades III and IV(high-differentiation).The grading scheme follows 4 stages:(1)training a Super Resolution Generative Adversarial Network(SRGAN)migration learning model on the Lung Nodule Analysis 2016 Dataset,and employing this model to reconstruct Super Resolution Images of the SHCC Dataset(SR-SHCC)images;(2)designing a texture clustering method based on Gray-Level Co-occurrence Matrix(GLCM)to segment tumour regions,which are Regions Of Interest(ROIs),from the original and SR-SHCC images,respectively;(3)extracting texture features on the ROIs;(4)performing statistical analysis and classifications.The segmentation achieved accuracies of 0.9049 and 0.8590 in the original SHCC images and the SR-SHCC images,respectively.The classification achived an accuracy of 0.838 and an Area Under the ROC Curve(AUC)of 0.84.The grading scheme can effectively reduce poor impacts on the texture analysis of SHCC ROIs.It may play a guiding role for physicians in early diagnoses of medium-differentiation and high-differentiation in SHCC. | Bei Hui Yanbo Liu Jiajun Qiu Likun Cao Lin Ji Zhiqiang He | 2021 | Tsinghua Science and Technology2021，26，2： | 3 |
| 5 | Air plasma-sprayed high-entropy (Y_(0.2)Yb_(0.2)Lu_(0.2)Eu_(0.2)Er_(0.2))_(3)Al_(5)O_(12) coating with high thermal protection performance显示文摘High-entropy rare-earth aluminate(Y_(0.2)Yb_(0.2)Lu_(0.2)Eu_(0.2)Er_(0.2))_(3)Al_(5)O_(12)(HE-RE_(3)Al_(5)O_(12))has been considered as a promising thermal protection coating(TPC)material based on its low thermal conductivity and close thermal expansion coefficient to that of Al2O3.However,such a coating has not been experimentally prepared,and its thermal protection performance has not been evaluated.To prove the feasibility of utilizing HE-RE_(3)Al_(5)O_(12) as a TPC,HE-RE_(3)Al_(5)O_(12) coating was deposited on a nickelbased superalloy for the first time using the atmospheric plasma spraying technique.The stability,surface,and cross-sectional morphologies,as well as the fracture surface of the HE-RE_(3)Al_(5)O_(12) coating were investigated,and the thermal shock resistance was evaluated using the oxyacetylene flame test.The results show that the HE-RE_(3)Al_(5)O_(12) coating can remain intact after 50 cycles at 1200℃ for 200 s,while the edge peeling phenomenon occurs after 10 cycles at 1400℃ for 200 s.This study clearly demonstrates that HE-RE_(3)Al_(5)O_(12) coating is effective for protecting the nickel-based superalloy,and the atmospheric plasma spraying is a suitable method for preparing this kind of coatings. | Kailun WANG Jinpeng ZHU Hailong WANG Kaijun YANG Yameng ZHU Yubin QING Zhuang MA Lihong GAO Yanbo LIU Sihao WEI Yongchun SHU Yanchun ZHOU Jilin HE | 2022 | Journal of Advanced Ceramics2022，11，10： | 2 |

| 9 | A tunable ferroelectric based unreleased RF resonator显示文摘This paper introduces the first tunable ferroelectric capacitor(FeCAP)-based unreleased RF MEMS resonator,integrated seamlessly in Texas Instruments’130 nm Ferroelectric RAM(FeRAM)technology.The designs presented here are monolithically integrated in solid-state CMOS technology,with no post-processing or release step typical of other MEMS devices.An array of FeCAPs in this complementary metal-oxide-semiconductor(CMOS)technology’s back-end-of-line(BEOL)process were used to define the acoustic resonance cavity as well as the electromechanical transducers.To achieve high quality factor(Q)of the resonator,acoustic waveguiding for vertical confinement within the CMOS stack is studied and optimized.Additional design considerations are discussed to obtain lateral confinement and suppression of spurious modes.An FeCAP resonator is demonstrated with fundamental resonance at 703 MHz and Q of 1012.This gives a frequency-quality factor product f·Q=7:11×10^(11) which is 1.6×higher than the most state-of-the-art Pb(Zr,Ti)O_(3)(PZT)resonators.Due to the ferroelectric characteristics of the FeCAPs,transduction of the resonator can be switched on and off by adjusting the electric polarization.In this case,the resonance can be turned off completely at±0.3 V corresponding to the coercive voltage of the constituent FeCAP transducers.These novel switchable resonators may have promising applications in on-chip timing,ad-hoc radio front ends,and chip-scale sensors. | Yanbo He Bichoy Bahr Mengwei Si Peide Ye Dana Weinstein | 2020 | Microsystems & Nanoengineering2020，6，1： | 1 |
| 10 | Interlayer ligand engineering of β-Ni(OH)2 for oxygen evolution reaction显示文摘Oxygen evolution reaction(OER)is a bottleneck process for many electrochemical devices due to the sluggish kinetics,for which advanced electrocatalysts should be carefully designed.Nickle-based materials have been extensively studied to catalyze OER.However,their performances are still below the expectation and the active sites are often controversial.Herein,we have successfully modulated the electronic and surface properties of layeredβ-Ni(OH)2 by the interlayer ligand engineering,aiming to design novel efficient electrocatalysts and unveil the catalysis mechanism.By one-step solvothermal reaction,alkoxyl substitutedβ-Ni(OH)2 with variable interlayer distances is obtained,and the ethoxyl substituted one(NiEt)shows great potential for efficient OER.With the assistance of powder X-ray diffraction and crystalline structure computational simulation,the formula of alkoxyl substitutedβ-Ni(OH)2 are determined.Operando X-ray absorption spectroscopy studies combined with ex-situ analyses revealed that the critical active species of NiEt is formed via hydroxylation and subsequent de-protonation,with high valent Niδ+(3<δ≤3.66).The corresponding catalytic reaction pathway and mechanism are proposed. | Junying He Yuqin Zou Yucheng Huang Chenhui Li Yanbo Liu Ling Zhou Chung-Li Dong Xia Lu Shuangyin Wang | 2020 | Science China Chemistry2020，63，11： | 1 |

| 14 | Co‑packaged optics(CPO):status,challenges,and solutions显示文摘Due to the rise of 5G,IoT,AI,and high-performance computing applications,datacenter trafc has grown at a compound annual growth rate of nearly 30%.Furthermore,nearly three-fourths of the datacenter trafc resides within datacenters.The conventional pluggable optics increases at a much slower rate than that of datacenter trafc.The gap between application requirements and the capability of conventional pluggable optics keeps increasing,a trend that is unsustainable.Copackaged optics(CPO)is a disruptive approach to increasing the interconnecting bandwidth density and energy efciency by dramatically shortening the electrical link length through advanced packaging and co-optimization of electronics and photonics.CPO is widely regarded as a promising solution for future datacenter interconnections,and silicon platform is the most promising platform for large-scale integration.Leading international companies(e.g.,Intel,Broadcom and IBM)have heavily investigated in CPO technology,an inter-disciplinary research feld that involves photonic devices,integrated circuits design,packaging,photonic device modeling,electronic-photonic co-simulation,applications,and standardization.This review aims to provide the readers a comprehensive overview of the state-of-the-art progress of CPO in silicon platform,identify the key challenges,and point out the potential solutions,hoping to encourage collaboration between diferent research felds to accelerate the development of CPO technology. | Min Tan Jiang Xu Siyang Liu Junbo Feng Hua Zhang Chaonan Yao Shixi Chen Hangyu Guo Gengshi Han Zhanhao Wen Bao Chen Yu He Xuqiang Zheng Da Ming Yaowen Tu Qiang Fu Nan Qi Dan Li Li Geng Song Wen Fenghe Yang Huimin He Fengman Liu Haiyun Xue Yuhang Wang Ciyuan Qiu Guangcan Mi Yanbo Li Tianhai Chang Mingche Lai Luo Zhang Qinfen Hao Mengyuan Qin | 2023 | Frontiers of Optoelectronics2023，16，1： | 1 |
| 15 | Low-Temperature Soft-Cover-Assisted Hydrolysis Deposition of Large-Scale TiO_2 Layer for Efficient Perovskite Solar Modules显示文摘Perovskite solar cells with TiO_2 electron transport layers exhibit power conversion efficiency(PCE) as high as 22.7% in single cells. However, the preparation process of the TiO_2 layer is adopted by an unscalable method or requires high-temperature sintering, which precludes its potential use for mass production of flexible devices. In this study, a scalable low-temperature softcover-assisted hydrolysis(SAH) method is presented,where the precursor solution is sandwiched between a soft cover and preheated substrate to form a closed hydrolysis environment. Compact homogeneous TiO_2 films with a needle-like structure were obtained after the hydrolysis of a TiCl_4 aqueous solution. Moreover, by careful optimization of the TiO_2 fabrication conditions, a high PCE of 14.01% could be achieved for a solar module(4 × 4 cm^2) prepared using the SAH method. This method provides a novel approach for the efficient scale-up of the low-temperature TiO_2 film growth for industrial applications. | Jinjin He Enbing Bi Wentao Tang Yanbo Wang Xudong Yang Han Chen Liyuan Han | 2018 | Nano-Micro Letters2018，10，3： | 1 |

| 17 | Relationship between the types of binary alloy phase diagrams of Ⅷ and IB group elements and the Mendeleev numbers显示文摘The relationship between the types of binary alloy phase diagrams of VIII and IB group elements and the Mendeleev numbers was discussed for the first time using the VIII and IB group elements as solvent metals (A) and the other elements as solute metals (B), basesd on their alloy phase diagram types. The Mendeleev numbers of the solvent metals and the solute metals were expressed as MA, and MB, respectively. A two-dimension map of MA/MB was drawn. It is indicated that there is an oblique line in the map, which divides the binary alloy phase diagram types of solvent metals into two symmetry parts, the phase diagram types of the other elements with solvent metals located at the above or down of the line respectively, while on the line, △M=0. The phase diagrams between the solvent metals basically are simple systems, mainly belong to the types of continues solid solution and the peritectic (about 40% for each type). The solvent metals can be divided into three groups: Co, Jr, Rh, Ni, Pt, and Pd as the first group; Ag, Au, and Cu as the second group; and Fe, Os, and Ru as the third group. The characteristics of the phase diagrams formed between the elements in each group were discussed. About 80% phase diagrams belong to complex systems and less than 20% belong to the simple systems. The regular variation of the chemical scale, the metallic radii of the atoms, the number of valence electrons, and the first ionization energy with the Mendeleev numbers and the crystal structure were introduced as well. | HE Chunxiao, LI Guanfang, LUO Yanbo, and LI Yanan Kunming Institute of Precious Metals, Kunming 650221, China | 2002 | Rare Metals2002，21，1： | 0 |
| 18 | Optimal Allocation of Comprehensive Resources for Large-Scale Access of Electric Kiln to the Distribution Network显示文摘With the significant progress of the“coal to electricity”project,the electric kiln equipment began to be connected to the distribution network on a large scale,which caused power quality problems such as low voltage,high harmonic distortion rate,and high reactive power loss.This paper proposes a two-stage power grid comprehensive resource optimization configuration model.A multi-objective optimization solution based on the joint simulation platform of Matlab and OpenDSS is developed.The solution aims to control harmonics and optimize reactive power.In the first stage,a multi-objective optimization model is established to minimize the active network loss,voltage deviation,and equipment cost under the constraint conditions of voltage margin,power factor,and reactive power compensation capacity.Furthermore,the first stage uses a particle swarm optimization(PSO)algorithm to optimize the location and capacity of both series and parallel compensation devices in the distribution network.In the second stage,the optimal configuration model of the active power filter assumes the cost of the APF as the objective function and takes the harmonic voltage content rate,the total voltage distortion rate,and the allowable harmonic current as the constraint conditions.The proposed solution eliminates the harmonics by uniformly configuring active filters in the distribution network and centrally control harmonics at the system level.Finally,taking the IEEE33 distribution network as the object and considering the change of electric furnace permeability in the range of 20%–50%,the simulation results show that the proposed algorithm effectively reduces the distribution network’s loss,its harmonic content and significantly improve its voltage. | Dan Wu Yanbo Che Wei Li Wei He Dongyi Li | 2021 | Energy Engineering2021，118，5： | 0 |
| 19 | Band gap structure analysis of phononic crystal rods with hybrid shunted piezoelectric patches显示文摘The band gap structures by arranging hybrid shunted piezoelectric materialswith resistance inductive(RL) circuit and negative impedance converter(NIC) closely and at intervals are presented.The theoretical model is built using transfer matrix method.Then the MATLAB computing language is utilized to simulate the band gap structures.Meanwhile,the effects of the resistance,inductance and capacitance on the local resonant gap are studied.By comparing different combinations of resistance,inductance and capacitance as well as different arrangement of circuits,a 13 kHz band gap is reached under the effect of arranging hybrid periodic shunted piezoelectric patches at intervals and the stability of the system is also analyzed.It is proved that utilizing hybrid shunted piezoelectric patches would have a clear impact on the band gap structure of phononic crystal rods.Moreover,the band gap would be clearly enlarged by arranging hybrid piezoelectric patches at intervals. | HE Yanbo DU Jingtao | 2015 | Chinese Journal of Acoustics2015，34，4： | 0 |
| 20 | Atomic-resolution investigation of structural transformation caused by oxygen vacancy in La_(0.9)Sr_(0.1)TiO_(3+δ)titanate layer perovskite ceramics显示文摘Perovskite functional ceramics have been widely applied for thermal protection owing to their unique physical properties.However,formation of oxygen vacancies under external stimuli usually limits their performance in practical applications.Therefore,the mechanism of the effect of oxygen vacancy on the layer structure of perovskite La_(0.9)Sr_(0.1)TiO_(3+δ)was investigated by experiments and first-principles simulations.The experimental results showed that the lattice distortion occurred in oxygen-deficient environment to give a longer c-axis,along with a significant adjustment in the modes of A/B–O bond vibration,resulting in lower reflectivity.Advanced transmission electron microscopy studies revealed that oxygen vacancies induced localized atomic rearrangements via[TiO_(6)]layer movements to adapt to the lattice distortion.This eventually restructured a part of the layer interfaces by expanding the overlapping projection of atoms in the c-axial direction.The specific transformation process was described as a compendious process,while geometric phase analysis effectively clarified how oxygen vacancies can inhibit reflectivity on the layer structure.Thus,this study provides effective approaches for researching the effects of oxygen vacancy on the physical properties of orthorhombic layer perovskite structures,which may facilitate the development of perovskite-based functional devices. | Yang Zhao Yameng Zhu Jinpeng Zhu Hailong Wang Zhuang Ma Lihong Gao Yanbo Liu Kaijun Yang Yongchun Shu Jilin He | 2022 | Journal of Materials Science & Technology2022，，9： | 0 |
