| 1 | Achieving over 16% efficiency for single-junction organic solar cells显示文摘To achieve high photovoltaic performance of bulk hetero-junction organic solar cells(OSCs), a range of critical factors including absorption profiles, energy level alignment, charge carrier mobility and miscibility of donor and acceptor materials should be carefully considered. For electron-donating materials, the deep highest occupied molecular orbital(HOMO) energy level that is beneficial for high open-circuit voltage is much appreciated. However, a new issue in charge transfer emerges when matching such a donor with an acceptor that has a shallower HOMO energy level. More to this point, the chemical strategies used to enhance the absorption coefficient of acceptors may lead to increased molecular crystallinity, and thus result in less controllable phase-separation of photoactive layer. Therefore, to realize balanced photovoltaic parameters, the donor-acceptor combinations should simultaneously address the absorption spectra, energy levels, and film morphologies. Here, we selected two non-fullerene acceptors, namely BTPT-4F and BTPTT-4F, to match with a wide-bandgap polymer donor P2F-EHp consisting of an imidefunctionalized benzotriazole moiety, as these materials presented complementary absorption and well-matched energy levels. By delicately optimizing the blend film morphology, we demonstrated an unprecedented power conversion efficiency of over 16% for the device based on P2F-EHp:BTPTT-4F, suggesting the great promise of materials matching toward high-performance OSCs. | Baobing Fan Difei Zhang Meijing Li Wenkai Zhong Zhaomiyi Zeng Lei Ying Fei Huang Yong Cao | 2019 | Science China Chemistry2019，62，6： | 38 |
| 2 | Thermodynamic properties of metamizol monohydrate in pure and binary solvents at temperatures from(283.15 to 313.15) K显示文摘The thermodynamic properties of metamizol monohydrate in pure solvents(methanol,ethanol,n-propanol and isopropanol) and two binary mixed solvent systems including(methanol+ethanol) and(methanol+isopropanol) were measured from 283.15 K to 313.15 K by gravimetric method under atmospheric pressure thought as 0.1 MPa.The modi fied Apelblat equation,the CNIBS/R-K equation,the Hybrid model and the NRTL model were used to correlate the solubility of metamizol monohydrate,respectively.The results show that the solubility of metamizol monohydrate in all the tested solvents increases with the rising temperature which means that it has temperature dependence.What's more,the effects of solvent components of the binary solvent mixtures on solubility were discussed,it illustrates that the increasing of the molar fraction of methanol gives the system a greater dissolving power.Furthermore,according to the NRTL model,the enthalpy,the Gibbs energy and the entropy of the mixing process were also obtained and discussed. | Mingxia Guo Qiuxiang Yin Chang Wang Yaohui Huang Yang Li Zaixiang Zhang Xia Zhang Zhao Wang Meijing Zhang Ling Zhou | 2017 | Chinese Journal of Chemical Engineering2017，25，10： | 3 |

| 5 | Boosting electroluminescence performance of all solution processed In P based quantum dot light emitting diodes using bilayered inorganic hole injection layers显示文摘The development of high-performance In P-based quantum dot light-emitting diodes(QLEDs)has become the current trend in ecofriendly display and lighting technology.However,compared with Cd-based QLEDs that have already been devoted to industry,the efficiency and stability of In P-based QLEDs still face great challenges.In this work,colloidal Ni Oxand Mg-doped Ni Oxnanocrystals were used to prepare a bilayered hole injection layer(HIL)to replace the classical polystyrene sulfonate(PEDOT:PSS)HIL to construct high-performance In Pbased QLEDs.Compared with QLEDs with a single HIL of PEDOT:PSS,the bilayered HIL enables the external quantum efficiencies of the QLEDs to increase from 7.6%to 11.2%,and the T_(95)lifetime(time that the device brightness decreases to 95%of its initial value)under a high brightness of 1000 cd m^(-2)to prolong about 7 times.The improved performance of QLEDs is attributed to the bilayered HIL reducing the mismatched potential barrier of hole injection,narrows the potential barrier difference of indium tin oxide(ITO)/hole transport layer interface to promote carrier balance injection,and realizes high-efficiency radiative recombination.The experimental results indicate that the use of bilayered HILs with p-type Ni Oxmight be an efficient method for fabricating high-performance In P-based QLEDs. | QIUYAN LI SHENG CAO PENG YU MEIJING NING KE XING ZHENTAO DU BINGSUO ZOU JIALONG ZHAO | 2022 | Photonics Research2022，10，9： | 0 |

| 7 | Elevated serum uric acid level as a predictor for cardiovascu-lar and all-cause mortality in Chinese patients with high cardiovascular risk显示文摘Objective To assess the predictive value of serum uric acid levels for cardiovascular and all-cause mortality in a large prospective population based study.Methods The study was based on 3648 participants in Shanghai and Beijing,who were inpatients with high cardiovascular(CV) risk at baseLine (2004.7 to 2005.1),and blood was taken.Follow-up for death from cardiovascular disease and any cause was complete until January 1,2006.Results The mean follow-up was 1 years.There were 303 deaths during follow-up,of which 121 were cardiovascular.Crude mortality rates were 8.3 % for all patients,6.8% for female patients (116/1715),and 9.7% (187/1933) for male patients.Among men,patients in the lower and higher uric acid groups had increased cardiac and overall mortality risks compared with patients in the normal uric acid groups.Similar relation was found in women but not statistically significant.After adjusting for other conventional risk factors (age,diabetes,hypertension,diuretic use and smoking),baseline uric acid level was still associated with increased risk for death from cardiovascular disease (P=0.005),or death from all causes (P=0.014) Conclusion Our data suggest that abnormal serum uric acid levels are independently and significantly associated with risk of cardiovascular and all-cause mortality.(J Geriatr Cardiol 2008;5:15-20) | Yongquan Wu Meijing Li Jue Li Yingyi Luo Yan Xing Dayi Hu | 2008 | Journal of Geriatric Cardiology2008，5，1： | 0 |
| 8 | Characterization and structure analysis of the heterosolvate of erythromycin thiocyanate显示文摘Erythromycin thiocyanate is widely used for the production of other macrolide antibiotics. In this work, a novel heterosolvate of this pharmaceutical compound has been obtained and characterized for the first time, which was transformed from the dihydrate form in the acetone solvent through evaporation crystallization. Thermal behavior together with compositional analysis revealed that both water and acetone molecules participated in the formation of the crystal lattice which is rarely reported before. The general chemical name of the heterosolvate may be defined as erythromycin thiocyanate sesquihydrate hemiacetonate. Furthermore, studies on solid-state spectral analysis provided strong evidence of intermolecular hydrogen bonds in heterosolvate crystals. According to the crystal structure determined by single crystal X-ray diffraction, the formation mechanism of the heterosolvate is proposed in which strong multihydrogen bondings between water and solute molecules form the layer structure. While acetone molecules form single-hydrogen bonds with solutes and reside in channels between layers. This well explains why acetone solvent is easy to escape from the crystal structure during desolvation. | Yuanjie Li Qiuxiang Yin Meijing Zhang Ying Bao Baohong Hou Jingkang Wang Jiting Huang Ling Zhou | 2022 | Chinese Journal of Chemical Engineering2022，35，4： | 0 |
| 9 | Generation of functional oligopeptides that promote osteogenesis based on unsupervised deep learning of protein IDRs显示文摘Deep learning(DL)is currently revolutionizing peptide drug development due to both computational advances and the substantial recent expansion of digitized biological data.However,progress in oligopeptide drug development has been limited,likely due to the lack of suitable datasets and difficulty in identifying informative features to use as inputs for DL models.Here,we utilized an unsupervised deep learning model to learn a semantic pattern based on the intrinsically disordered regions of~171 known osteogenic proteins.Subsequently,oligopeptides were generated from this semantic pattern based on Monte Carlo simulation,followed by in vivo functional characterization.A five amino acid oligopeptide(AIB5P)had strong bone-formation-promoting effects,as determined in multiple mouse models(e.g.,osteoporosis,fracture,and osseointegration of implants).Mechanistically,we showed that AIB5P promotes osteogenesis by binding to the integrinα5 subunit and thereby activating FAK signaling.In summary,we successfully established an oligopeptide discovery strategy based on a DL model and demonstrated its utility from cytological screening to animal experimental verification. | Mingxiang Cai Baichuan Xiao Fujun Jin Xiaopeng Xu Yuwei Hua Junhui Li Pingping Niu Meijing Liu Jiaqi Wu Rui Yue Yong Zhang Zuolin Wang Yongbiao Zhang Xiaogang Wang Yao Sun | 2022 | Bone Research2022，10，2： | 0 |
| 10 | Research on ECMS Based on Segmented Path Braking Energy Recovery in a Fuel Cell Vehicle显示文摘Proton exchange membrane fuel cells are widely regarded as having the potential to replace internal combustion engines in vehicles.Since fuel cells cannot recover energy and have a slow dynamic response,they need to be used with different power sources.Developing efficient energy management strategies to achieve excellent fuel economy is the goal of research.This paper proposes an adaptive equivalent fuel minimum consumption strategy(AECMS)to solve the problem of the poor economy of the whole vehicle caused by the wrong selection of equivalent factors(EF)in traditional ECMS.In this method,the kinematics interval is used to update the equivalent factor by considering the penalty term of energy recovery on SOC changes.Finally,the optimized equivalent factor is substituted into the optimization objective function to achieve efficient energy regulation.Simulation results under the New European Driving Cycle show that compared with the traditional ECMS based on fixed SOC benchmarks,the proposed method improves fuel economy by 1.7%while ensuring vehicle power and increases SOC by 30%. | Wen Sun Meijing Li Guoxiang Li Ke Sun Shuzhan Bai | 2024 | Energy Engineering2024，121，1： | 0 |
