| 2 | Progress in next-generation organic electroluminescent materials:material design beyond exciton statistics显示文摘Exciton(or spin)statistics is a physical principle based on the statistics of spin multiplicity.In electroluminescence,injected electrons and holes have randomized spin states,and usually form singlet or triplet excitons in the ratio of 1:3.Exciton statistics determines that the upper limit of internal quantum efficiency is 25%in fluorescent devices,since only singlet exciton can decay radiatively.However,both experimental and theoretical evidence indicate that the actual efficiency can exceed the exciton statistics limit of 25%by utilizing materials with special electronic structure and optimized device structures.These results bring light to break through the exciton statistics limit and develop new-generation fluorescent materials with low cost and high efficiency.Recently,the exciton statistics,which has attracted great attention in the past decade,is being rejuvenated due to the discovery of some fluorescent materials with abnormally high efficiencies.In view of their significance in theoretical research of organic semiconductors and developing new-generation OLED materials,such materials are widely investigated in both academic institutions and industry.Several key issues still require further clarification for this kind of materials,such as the molecular design concepts.Herein,we review the progress of the materials with efficiency exceeding the exciton statistics limit,and the routes to improve exciton utilization efficiency.In the end,we present an innovative pathway to fully harvest the excitons in fluorescent devices,namely,'hot exciton'model and relevant fluorescence material with hybridized local and charge-transfer(HLCT)excited state. | YAO Liang YANG Bing MA YuGuang | 2014 | Science China Chemistry2014，57，3： | 11 |

| 4 | Effect of SiC particle addition on microstructure of Mg_2Si/Al composite显示文摘In the present study, by adding SiC particles into Al-Si-Mg melt, Mg2Si and SiC particles hybrid reinforced Al matrix composites were fabricated through the Mg2Si in situ synthesis in melt combined with the SiC ex situ stir casting. The as-cast microstructure containing primary Mg2Si and SiC particles that distribute homogenously in Al matrix was successfully achieved. The effects of SiC particle addition on the microstructure of Mg2Si/Al composites were investigated by using scanning electron microscopy(SEM) and XRD. The results show that, with increasing the fraction of the SiC particles from 5wt.% to 10wt.%, the morphologies of the primary Mg2Si particulates in the prepared samples remain polygonal, but the size of the primary phase decreases slightly. However, when the SiC particle addition reaches 15wt.%, the morphologies of the primary Mg2Si particulates change partially from polygonal to quadrangular with a decrease in size from 50 μm to 30 μm. The size of primary Al dendrites decreases with increasing fraction of the SiC particles from 0wt.% to 15wt.%. The morphology of the eutectic Mg2Si phase changes from a fi ber-form to a short fi ber-form and/or a dot-like shape with increasing fraction of the SiC particles. Furthermore, no signifi cant change in dendrite arm spacing(DAS) was observed in the presence of SiC particles. | Zhao Yuguang Liu Xiaobo Yang Yuanyuan Bian Tianjun | 2014 | China Foundry2014，11，2： | 8 |
| 5 | ~1H nuclear magnetic resonance-based metabolomic study on efficacy of Qingrehuatan decoction against abundant phlegm-heat syndrome in young adults with essential hypertension显示文摘OBJECTIVE: To observe the influence of Qingrehuatan decoction(QRHT) on serum metabolic profile in young essential hypertension(YEH) patients with abundant phlegm-heat syndrome and provide a basis for treatment with the decoction.METHODS: Twelve male YEH patients were randomly selected and serum samples were collected for examination before and after 4 weeks of thetreatment with QRHT. Twelve healthy males were randomly selected and their serum samples were collected as a control. All serum samples were detected using metabolomic technology with1 H nuclear magnetic resonance. Differences in metabolites were studied by principal component analysis and partial least squares-discriminate analysis,which produced scores and loadings plots.RESULTS: After 4 weeks of treatment, serum substances could be distinguished between the YEH patients with abundant phlegm-heat syndrome and the control patients. The specific serum endogenous metabolites tended to improve after the treatment. QRHT can appropriately increase the levels of glucose, lactic acid, citric acid, high-density lipoprotein, phosphatidylcholine, glycerophosphate choline, hydroxybutyrate, alanine, and glutamate.QRHT could also decrease the levels of low-density lipoprotein/very low-density lipoprotein, lipids,N-acetyl glycoprotein, and O-acetyl glycoprotein.CONCLUSION: QRHT can effectively ameliorate metabolic disorders in YEH Patients with abundant phlegm- heat syndrome.1H NMR-based metabolomic technology can provide an objective basis for the treatment of YEH patients with abundant phlegm-heat syndrome using QRHT. | Feng Xuanchao Yang Zheng Chu Yuguang Du Bai Su Mei Li Yi Wang Yinghong Jiang Chunying Hu Yuanhui | 2015 | Journal of Traditional Chinese Medicine2015，35，1： | 6 |
| 6 | Quantum network communication: a discrete-time quantum-walk approach显示文摘We study the problem of quantum multi-unicast communication over the butterfly network in a quantum-walk architecture, where multiple arbitrary single-qubit states are transmitted simultaneously between multiple source-sink pairs. Here, by introducing quantum walks, we demonstrate a quantum multiunicast communication scheme over the butterfly network and the inverted crown network, respectively,where the arbitrary single-qubit states can be efficiently transferred with both the probability and the state fidelity one. The presented result concerns only the butterfly network and the inverted crown network, but our techniques can be applied to a more general graph. It paves a way to combine quantum computation and quantum network communication. | Yuguang YANG Jiajie YANG Yihua ZHOU Weimin SHI Xiubo CHEN Jian LI Huijuan ZUO | 2018 | Science China(Information Sciences)2018，61，4： | 5 |
| 7 | Fault tolerant quantum secret sharing against collective-amplitude-damping noise显示文摘We present a quantum secret sharing protocol against collective-amplitude-damping noise. Each logical qubit is encoded in two qubit noiseless states. So it can function over such a noisy channel. The two agents encode their messages on each logical qubit only by performing a permutation operation on two physical qubits. Although each logical qubit received by each agent only carries a bit of information, the boss Alice can read out her agents' information by discriminating two orthogonal states by performing single-qubit measurements assisted by local operation and classical communication (LOCC). | YANG YuGuang CHAI HaiPing WANG Yuan TENG YiWei WEN QiaoYan | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，9： | 4 |
| 8 | Numerical aerodynamic analysis of bluff bodies at a high Reynolds number with three-dimensional CFD modeling显示文摘This paper focuses on numerical simulations of bluff body aerodynamics with three-dimensional CFD(computational fluid dynamics) modeling,where a computational scheme for fluid-structure interactions is implemented.The choice of an appropriate turbulence model for the computational modeling of bluff body aerodynamics using both two-dimensional and three-dimensional CFD numerical simulations is also considered.An efficient mesh control method which employs the mesh deformation technique is proposed to achieve better simulation results.Several long-span deck sections are chosen as examples which were stationary and pitching at a high Reynolds number.With the proposed CFD method and turbulence models,the force coefficients and flutter derivatives thus obtained are compared with the experimental measurement results and computed values completely from commercial software.Finally,a discussion on the effects of oscillation amplitude on the flutter instability of a bluff body is carried out with extended numerical simulations.These numerical analysis results demonstrate that the proposed three-dimensional CFD method,with proper turbulence modeling,has good accuracy and significant benefits for aerodynamic analysis and computational FSI studies of bluff bodies. | BAI YuGuang YANG Kai SUN DongKe ZHANG YuGuang KENNEDY David WILLIAMS Fred GAO XiaoWei | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，2： | 4 |
| 9 | Different Effects of Wet and Dry Grinding on the Activation of Iron Ore Tailings显示文摘Improving the activity of Iron Ore Tailings(IOTs)to utilize them as a mineral admixture in cement-based minerals is still challenging.In this paper,the wet grinding technology was employed to stimulate the activity of IOTs,and the traditional dry grinding method was used as a reference.The effect of wet grinding on the activation of IOTs was evaluated through ion leaching from an alkaline solution and the reactivity index.Additionally,a detailed comparison between Dry-grinding Iron Ore Tailings(DIOTs)and Wet-grinding Iron Ore Tailings(WIOTs)was made.This comparison was based on particle characteristics,crystal structures,chemical structure,and surface properties.The results showed that the particle size of IOTs reduced rapidly during wet grinding.In addition,WIOTs had a higher activity index compared to DIOTs.The storage of lattice distortions in the quartz crystal structure was also more significant during the wet grinding process than during the dry grinding process.Moreover,both prolonged dry and wet grinding could destabilize the Si-O bond and decrease the surface binding energy. | Yingchun Yang Liqing Chen Yuguang Mao | 2021 | Journal of Renewable Materials2021，9，12： | 3 |

| 15 | Efficacy of Renshen(Radix Ginseng) plus Fuzi(Radix Aconiti Lateralis Preparata) on myocardial infarction by enhancing autophagy in rats显示文摘OBJECTIVE:To elucidate the protective effects of Renshen(Radix Ginseng)and Fuzi(Radix Aconiti Lateralis Preparata)on myocardial infarction(MI)through regulating myocardial autophagy.METHODS:Thirty-one male Sprague-Dawley rats were randomized into five groups(n=6 or 7 for each).After treatment for 3 weeks,electrocardiogram(ECG)and cardiac function were recorded.Hematoxylin and eosin(HE)staining was used to detect pathological changes in the heart.Enzyme-linked immunosorbent assay(ELISA)was used to detect serum B-type brain natriuretic peptide(BNP),cardiac troponin T(c Tn T),tumor necrosis factor-α(TNF-α),and serum inflammatory cytokines.Metabolomic analysis was used to identify differential biomarkers of MI in rats.Immunohistochemistry and western blotting were used to detect BNP,cTnT,TNF-α,LC3B,Beclin-1,p62,and adenosine monophosphate activated protein kinase(AMPK)expression in cardiac tissue.RESULTS:Fuzi(Radix Aconiti Lateralis Preparata)alone or Renshen(Radix Ginseng)plus Fuzi(Radix Aconiti Lateralis Preparata)markedly ameliorated cardiac dysfunction and abnormal ECGs,demonstrated by decreases in the heart weight/body weight ratio,BNP,and c Tn T.Pro-inflammation cytokine interleukin(IL)-1αsignificantly decreased and anti-inflammatory cytokine IL-10 significantly increased in Renshen(Radix Ginseng)single or Renshen(Radix Ginseng)plus Fuzi(Radix Aconiti Lateralis Preparata)groups compared with the control group.HE results suggested that co-treatment produced a greater reduction in cardiomyocyte cross-sectional area than Renshen(Radix Ginseng)or Fuzi(Radix Aconiti Lateralis Preparata)alone.Renshen(Radix Ginseng)plus Fuzi(Radix Aconiti Lateralis Preparata)reversed these changes to different degrees in MI rats.Furthermore,Renshen(Radix Ginseng)plus Fuzi(Radix Aconiti Lateralis Preparata)down-regulated LC3 B,Beclin-1,and AMPK expression in cardiac tissue and upregulated p62 expression.CONCLUSIONS:Renshen(Radix Ginseng)plus Fuzi(Radix Aconiti Lateralis Preparata)may have a greater effect on heart injury induced by MI in rats than Fuzi(Radix Aconiti Lateralis Preparata)treatment alone,and the underlying mechanism may be associated with the regulation of myocardial autophagy and anti-inflammation effects.These results provide fresh insight into the mechanism of co-treatment with Renshen(Radix Ginseng)and Fuzi(Radix Aconiti Lateralis Preparata)for MI. | YANG Liang HUANG Guangyao WANG Yuguang HAN Baoqi ZHENG Bin ZHU Jinmiao GAO Shan GAO Yue | 2021 | Journal of Traditional Chinese Medicine2021，41，6： | 1 |

| 20 | Energetic electron detection packages on board Chinese navigation satellites in MEO显示文摘Energetic electron measurements and spacecraft charging are of great significance for theoretical research in space physics and space weather applications.In this paper,the energetic electron detection package(EEDP)deployed on three Chinese navigation satellites in medium Earth orbit(MEO)is reviewed.The instrument was developed by the space science payload team led by Peking University.The EEDP includes a pinhole medium-energy electron spectrometer(MES),a high-energy electron detector(HED)based onΔE-E telescope technology,and a deep dielectric charging monitor(DDCM).The MES measures the energy spectra of 50−600 keV electrons from nine directions with a 180°×30°field of view(FOV).The HED measures the energy spectrum of 0.5−3.0 MeV electrons from one direction with a 30°cone-angle FOV.The ground test and calibration results indicate that these three sensors exhibit excellent performance.Preliminary observations show that the electron spectra measured by the MES and HED are in good agreement with the results from the magnetic electron-ion spectrometer(MagEIS)of the Van Allen Probes spacecraft,with an average relative deviation of 27.3%for the energy spectra.The charging currents and voltages measured by the DDCM during storms are consistent with the highenergy electron observations of the HED,demonstrating the effectiveness of the DDCM.The observations of the EEDP on board the three MEO satellites can provide important support for theoretical research on the radiation belts and the applications related to space weather. | YuGuang Ye Hong Zou Qiu-Gang Zong HongFei Chen JiQing Zou WeiHong Shi XiangQian Yu WeiYing Zhong YongFu Wang YiXin Hao ZhiYang Liu XiangHong Jia Bo Wang XiaoPing Yang XiaoYun Hao | 2021 | Earth and Planetary Physics2021，5，2： | 1 |
