| 1 | Electrochemical conversion of CO2 to syngas with a wide range of CO/H2 ratio over Ni/Fe binary single-atom catalysts显示文摘A series of carbon-based binary single-atom catalysts of Fe and Ni coordinated by nitrogen are fabricated using a glucose-chelating method.Depending on the Ni/Fe content,they exhibit a wide-range of controllable CO/H2 ratio from 0.14 to 10.86,which is meaningful to specific chemical processes.The durability of the catalyst is evaluated over an 8-hour period with no significant degradation of activity.The variation of the faradaic efficiency with Ni/Fe content is justified by density-functional-theory based calculation of the reaction barrier in both hydrogen evolution and CO2 reduction reactions. | Meng Zhang Zheng Hu Lin Gu Qinghua Zhang Linghui Zhang Qian Song Wei Zhou Shi Hu | 2020 | Nano Research2020，13，12： | 8 |
| 2 | Chromopeptide A, a highly cytotoxic depsipeptide from the marine sediment-derived bacterium Chromobacterium sp. HS-13-94显示文摘A bicyclic depsipeptide, chromopeptide A(1), was isolated from a deep-sea-derived bacterium Chromobacterium sp. HS-13-94. Its structure was determined by extensive spectroscopic analysis and by comparison with a related known compound. The absolute configuration of chromopeptide A was established by X-ray diffraction analysis employing graphite monochromated Mo K_α radiation(λ ? 0.71073 ?) with small Flack parameter 0.03. Chromopeptide A suppressed the proliferation of HL-60, K-562, and Ramos cells with average IC_(50) values of 7.7, 7.0, and 16.5 nmol/L, respectively. | Zhenfang Zhou Xin Wang Hui Zhang Jingya Sun Linghui Zheng Hongchun Liu Jidong Wang Aijun Shen Meiyu Geng Yuewei Guo | 2015 | Acta Pharmaceutica Sinica B2015，5，1： | 6 |

| 6 | Improved phase field model of dislocation intersections显示文摘Revealing the long-range elastic interaction and short-range core reaction between intersecting dislocations is crucial to the understanding of dislocation-based strain hardening mechanisms in crystalline solids.Phase field model has shown great potential in modeling dislocation dynamics by both employing the continuum microelasticity theory to describe the elastic interactions and incorporating theγ-surface into the crystalline energy to enable the core reactions.Since the crystalline energy is approximately formulated by linear superposition of interplanar potential of each slip plane in the previous phase field model,it does not fully account for the reactions between dislocations gliding in intersecting slip planes.In this study,an improved phase field model of dislocation intersections is proposed through updating the crystalline energy by coupling the potential of two intersecting planes,and then applied to study the collinear interaction followed by comparison with the previous simulation result using discrete dislocation dynamics.Collinear annihilation captured only in the improved phase field model is found to strongly affect the junction formation and plastic flow in multislip systems.The results indicate that the improvement is essential for phase field model of dislocation intersections. | Songlin Zheng Dongchang Zheng Yong Ni Linghui He | 2018 | npj Computational Materials2018，，1： | 0 |
| 7 | Differences in vascular endothelial function and serum proteome between obese people with phlegm-dampness constitution and balanced constitution显示文摘OBJECTIVE:To evaluate the extent of vascular endothelial dysfunction and preliminary identify serum protein biomarkers associated with obese individuals at risk for cardiovascular disease(CVD).METHODS:Fifteen obese volunteers with the phlegmdampness constitution or balanced constitution were recruited for this study respectively.The clinical baseline data was collected,and the vascular endothelial function was evaluated using the EndoPAT?.Blood samples were collected for the serum proteome analysis.The differences in the serum protein expression levels between the two groups were detected and the protein interaction network analysis,correlation analysis,receiver operating characteristic(ROC)curve analysis,and random forest model investigation were conducted.RESULTS:There were no statistical differences found in the baseline data.For vascular endothelial function,the reactive hyperemia index(RHI)of the phlegm-dampness constitution obese group was significantly lower than that of the balanced constitution obese group(1.46±0.30 vs 2.82±0.78,P<0.0001),indicating vascular endothelial dysfunction.There are 66 differentially expressed serum proteins between the two groups.apolipoprotein A2(Apo A2),angiotensin-converting enzyme 2(ACE-2),interleukin-33(IL-33),and forkhead box P3(FoxP3)showed significant differences and area under curve values of their ROC curves were greater than 0.7 and correlated significantly with RHI.CONCLUSION:Vascular endothelial dysfunction was present in the phlegm-dampness constitution obese group.Thus,alterations in the expression levels of key serum proteins,including Apo A2,ACE-2,IL-33,and Fox P3 could serve as potential biomarkers in the obese population at risk of CVD. | ZHU Linghui SUN Ziwei GUAN Yuanyuan LIU Meiyi ZHENG Yi YU Ruoxi WANG Qi LI Lingru | 2024 | Journal of Traditional Chinese Medicine2024，44，1： | 0 |
| 8 | Enhanced thermal isolation in porous thermal barrier coatings by the formation of pore guided thermal-shock cracks显示文摘Pore structure design is an effective strategy to tailor the thermal isolation capability of thermal barrier coatings(TBCs).Pursuing optimal porosity is crucial to balance the requirements of thermal isolation and mechanical reliability since the pore structure shields thermal heat transfer but increases mechanical degradation.In this work,we investigate how thermal heat transfer couples with fracture propagation in porous TBCs by the using thermo-mechanical coupling phase field model for fracture.The simulated results show that cracks induced by thermal shock favor deflection that is sometimes perpendicular to the direction of heat flow.The thermal conductivity degradation by the transverse cracks significantly impedes thermal heat transfer,leads to enhanced reduction of the effective thermal conductivity of TBCs,decreases the average thermal stress of the substrate,and thus decreases the risk of the crack penetrating into the substrate.The numerical results demonstrate that the phase field method fully considering the thermo-mechanical interaction between cracks and pores can be a useful tool to improve the thermal isolation of porous TBCs under extreme thermal shock loadings through pore structure design. | ZHEN Yu WU KaiJin LIU MengQi ZHENG SongLin HE LingHui YU Yin NI Yong | 2023 | Science China(Technological Sciences)2023，66，4： | 0 |
