| 2 | Organic-semiconductor: Polymer-electret blends for high-performance transistors显示文摘As compared with polymer semiconductors, solution-processed small-moleculesemiconductors usually have poorer film-formation properties, which induceswide variations in device performance in terms of mobility and threshold voltage,thus severely limiting their commercial applications. In this work, we propose aneasily accessible method to improve the performance and reduce the variabilityof small-molecule organic field-effect transistors (OFETs) by blending organicsemiconductors with an insulator polymer, which is subsequently post-treatedby gate stress to generate an electret. By blending the organic semiconductor2,7-didodecyl[1]benzothieno[3,2-b][1]benzothiophene (C12-BTBT) with the insulatorpolystyrene, uniform transport layers with vertically phase segregated morphologyare obtained, from which the mobility and threshold voltage of OFETs are largelymanipulated. The OFETs exhibit field-effect mobilities as high as 7.5 cm2-V-l-s-1with an on/off ratio exceeding 106 in ambient conditions. This double-layerstructure provides an appropriate architecture for applying gate-stress to injectcharges into the insulating layer, forming an electret. The generation of theelectret is thermally accelerated and thus can be easily realized under moderategate-stress at elevated temperature (e.g., 60 ℃). After cooling, the electret layer servesas a floating-gate, which not only continuously tunes the threshold voltage andfield-effect mobility, but also helps minimize the contact resistances and optimizethe subthreshold swing. As an application of this method, a digital inverter isbuilt and its performance is optimized via in situ tuning of its individual transistors. | Peng Wei Shengtao Li Dongfan Li Han Yu Xudong Wang Congcong Xu Yaodong Yang Laju Bu Guanghao Lu | 2018 | Nano Research2018，11，11： | 5 |
| 3 | Size,morphology,and composition of lunar samples returned by Chang'E-5 mission显示文摘This study focuses on the physical and chemical properties of surficial lunar regolith(LR)samples returned from the Moon by the Chang’E-5(CE-5)mission.Insights regarding the effect of a new sampling geological site on the surficial lunar sample CE5 C0400 were illustrated using nondestructive techniques such as laser diffractometry coupled with image analysis,X-ray computed tomography,and field emission scanning electron microscopy equipped with energy dispersive spectroscopy,and Xray diffraction combined with Rietveld refinement.From the characterization analyses,the CE-5 sampling site in the northeastern Oceanus Procellarum on the Moon yields a unique collection of relatively regular-shaped and fine basalt-dominated particles.The median grain size D_(50) is(55.24±0.96)μm,falling within the relatively low end of the range of the Apollo lunar returned samples.The coefficient of uniformity C_(u)of 15.1 and the coefficient of curvature C_(c)of 1.7 could classify CE5 C0400 to be well-graded.The minerals in CE5 C0400 comprise approximately 44.5%pyroxene,30.4%plagioclase,3.6%olivine,and6.0%ilmenite.There is a relatively low content of approximately 15.5%glass phase in the CE-5 lunar sample.From the results,we deduce that the CE-5 LR structure could have mainly resulted from micrometeoroid impacts to achieve such a high level of maturity. | Hui Zhang Xian Zhang Guang Zhang Keqi Dong Xiangjin Deng Xiaosong Gao Yaodong Yang Yuan Xiao Xiao Bai Kaixin Liang Yiwei Liu Wenbin Ma Shaofan Zhao Ce Zhang Xiaojing Zhang Jian Song Wei Yao Hong Chen Weihua Wang Zhigang Zou Mengfei Yang | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，2： | 4 |

| 6 | N/Ce doped graphene supported Pt nanoparticles for the catalytic oxidation of formaldehyde at room temperature显示文摘Pt catalysts with nitrogen-doped graphene oxide (GO) as support and CeO_(2)as promoter were prepared by impregnation method,and their catalytic oxidation of formaldehyde (HCHO) at room temperature was tested.The Pt-CeO_(2)/N-rGO (reduced GO) with a mass fraction of 0.7% Pt and 0.8%CeO_(2)exhibited an excellent catalytic performance with the 100% conversion of HCHO at room temperature.Physicochemical characterization demonstrated that nitrogendoping greatly increased the defect degree and the specific surface area of GO,enhanced the dispersion of Pt and promoted more zero-valent Pt.The synergistic effect between CeO_(2)and Pt was also beneficial to the dispersion of Pt.Nitrogen-doping promoted the production of more Ce3+ions,generating more oxygen vacancies,which was conducive to O_(2)adsorption.As a result,the catalyst exhibited enhanced redox properties,leading to the best catalytic activity.Finally,an attempt to propose the reaction mechanism of HCHO oxidation has been made. | Yaodong Guo Zhaoying Di Xiaonan Guo Ying Wei Runduo Zhang Jingbo Jia | 2023 | Journal of Environmental Sciences2023，，3： | 2 |
| 7 | Supramolecular self-assembly of two-component systems comprising aromatic amides/Schiff base and tartaric acid显示文摘The gelating properties and thermotropic behaviors of stoichiometric mixtures of aromatic amides 1,2,and the aromatic Schiffbase 3 with tartaric acid(TA)were investigated.Among the three gelators,2-TA exhibited superior gelating ability.Mixture 2-TA exhibits a smectic B phase and an unidentified smectic mesophase during both heating and cooling runs.The results of Fourier transform infrared spectroscopy and X-ray diffraction revealed the existence of hydrogen bonding and rc-ninteractions in 2-TA systems,which are likely to be the dominant driving forces for the supramolecular selfassembly.Additionally,it was established that all of the studied gel self-assemblies and mesophases possess alamellar structure.The anion response ability of the tetrahydrofuran gel of 2-TA was evaluated and it was found that it was responsive to the stimuli of F,Cl,Br,I,AcO. | Xin Wang Wei Cui Bin Li Xiaojie Zhang Yongxin Zhang Yaodong Huang | 2020 | Frontiers of Chemical Science and Engineering2020，14，6： | 2 |
| 8 | Investigation of Different Coke Samples Adhering to Cyclone Walls of a Commercial RFCC Reactor显示文摘The microstructure and properties of the coke samples collected from 4 different wall regions of the cyclone in the reactor of a residue fluid catalytic cracking unit(RFCCU) were analyzed by using the scanning-electron microscope(SEM), and the possible coke formation processes were investigated as well. The results showed that some of the heavy nonvolatile oil droplets entrained in the flowing oil and gas mixture could possibly deposit or collide on the walls by gravity settling or turbulence diffusion, and then were gradually carbonized into solid coke by condensing and polymerization along with dehydrogenation. Meanwhile some of fine catalyst particles also built up and integrated into the solid coke. The coke can be classified into two types, namely, the hard coke and the soft coke, according to its property, composition and microstructure. The soft coke is formed in the oil and gas mixture's stagnant region where the oil droplets and catalyst particles are freely settled on the wall. The soft coke appears to be loose and contains lots of large catalyst particles. However, the hard coke is formed in the oil and gas mixture's flowing region where the oil droplets and catalyst particles diffuse towards the wall. This kind of coke is nonporous and very hard, which contains a few fine catalyst particles. Therefore, it is clear that the oil and gas mixture not only carries the oil droplets and catalyst particles, but also has the effects on their deposition on the wall, which can influence the composition and characteristics of deposited coke. | Li Xiaoman Song Jianfei Sun Guogang Yan Chaoyu Wei Yaodong | 2016 | China Petroleum Processing & Petrochemical Technology2016，18，1： | 1 |

| 12 | A handy method for estimating the particle concentration distribution in FCC risers using a gamma-ray transmission technique显示文摘A handy gamma-ray transmission method for estimating the particle concentration distribution in a fluid catalytic cracking(FCC) riser is proposed.The method is based on an empirical correlation ε(γ) =ε^(0.191+Φ^(2.5)+3Φ^(11)),which has only one unknown parameterε,hence only one single-beam experimental result is enough to estimate the particle concentration distribution in the riser.In order to verify the feasibility of this method,the particle concentrations of three cross-sections of the laboratory riser were measured and the distribution profiles were compared with those reported in the literature.Furthermore,by comparing other gamma-ray function methods applied in the measurement of risers,this method has distinct advantages,such as the device is simple and has no moving parts,the measurement is rapid,and the safety is high because only one gamma-ray beam is used.Therefore,the method has promising applications in estimating particle concentrations or monitoring operation conditions of risers. | Liu Xiaocheng Wei Yaodong Song Jianfei | 2014 | Petroleum Science2014，11，2： | 0 |
| 13 | Keyphrase Generation Based on Self-Attention Mechanism显示文摘Keyphrase greatly provides summarized and valuable information.This information can help us not only understand text semantics,but also organize and retrieve text content effectively.The task of automatically generating it has received considerable attention in recent decades.From the previous studies,we can see many workable solutions for obtaining keyphrases.One method is to divide the content to be summarized into multiple blocks of text,then we rank and select the most important content.The disadvantage of this method is that it cannot identify keyphrase that does not include in the text,let alone get the real semantic meaning hidden in the text.Another approach uses recurrent neural networks to generate keyphrases from the semantic aspects of the text,but the inherently sequential nature precludes parallelization within training examples,and distances have limitations on context dependencies.Previous works have demonstrated the benefits of the self-attention mechanism,which can learn global text dependency features and can be parallelized.Inspired by the above observation,we propose a keyphrase generation model,which is based entirely on the self-attention mechanism.It is an encoder-decoder model that can make up the above disadvantage effectively.In addition,we also consider the semantic similarity between keyphrases,and add semantic similarity processing module into the model.This proposed model,which is demonstrated by empirical analysis on five datasets,can achieve competitive performance compared to baseline methods. | Kehua Yang Yaodong Wang Wei Zhang Jiqing Yao Yuquan Le | 2019 | Computers, Materials & Continua2019，，8： | 0 |
| 14 | Review of biomechanical deviations among nonpregnant,pregnant,and postpartum cohorts显示文摘During pregnancy,women experience substantial changes in physiology,morphology,and hormonal systems.These changes have profound effects on the biomechanics of the human body,particularly the musculoskeletal system,resulting in discomfort,pain,and decreased body stability.Sufficient biomechanical knowledge is critical for understanding the etiology and precautions of musculoskeletal disorders.With awareness of health problems in the pregnant cohort,identification,intervention,and precaution of problems have garnered attention.Researchers have conducted studies to determine the biomechanics of pregnancy.There have been review studies on summarization.However,to the best of our knowledge,few studies have comprehensively described biomechanical changes throughout pre-,in-,and postpartum periods.This review analyzed available studies on biomechanical changes during these three periods in the electronic databases of PubMed,Scopus,and Cochrane from inception until June 2,2021.Synthesized the general information,age of the studied subjects,investigated periods,sample size,objectives,measurement tools,and outcomes of reviewed studies.And Using National Institutes of Health quality assessment tool for observational cohort and cross-sectional studies to assessment the quality of the reviewed articles.These studies revealed biomechanical deviations in body stability,motion patterns,and gait modes during these three periods.Regarding research content,there are insufficient studies on certain critical biomechanical aspects,such as the kinetic parameters of the inner body,which are the most direct factors related to musculoskeletal problems.According to the National Institutes of Health quality assessment tool for observational cohort and cross-sectional studies,a more comprehensive and explicit understanding of pregnancy biomechanics can be expected. | Wei Linjuan Wang Yan Peng Yinghu Tan Qitao Gu Yaodong Li Li Zhang Ming | 2023 | Medicine in Novel Technology and Devices2023，，2： | 0 |
