| 1 | Synaptobrevin-2 facilitates the trafficking and function of atrial SK2 channel显示文摘Dear Editor,Small conductance Ca2+-activated potassium (SK) channels are widely expressed in various tissues and play a unique role in regulating cell function by integrating cytosolic Ca2+ levels and membrane potential (Adelman et al., 2012). Xu et al. first identified SK channels in the heart and found that SK channels, particularly the SK2 channel, are preferentially expressed in human and mouse atrial myocytes but not in ventricular myocytes (Xu et al., 2003). This suggests that the | Tao Li Xuehui Fan Yiyan Yu Linlin Chen Wenjun Huang Yan Yang Jimin Cao Xiaorong Zeng Xiaoqiu Tan | 2018 | Science China(Life Sciences)2018，61，5： | 1 |

| 3 | A STUDY OF THE INFLUENCE OF INTERFACIAL DAMAGE ON STRESS CONCENTRATIONS IN INTRAPLY HYBRID COMPOSITES显示文摘In the axial tensile failure process of intraply hybrid composites, the breakage of some fibers may lead to interfacial damage, thus directly influencing the local stress concentrations near the sites of breakage. A modified shear-lag model, in which the interfacial damage is considered, is proposed. Based on the model, the influence of interfacial shear strength on the stress concentrations and the lengths of interfacial damage zone is first studied. The present results also provide an important theoretical basis for investigating the failure mechanism and hybrid effects for such kind of composites. | Zeng Qingdun Lin Xuehui (College of Traffic and Communications, South China University of Technology,Guangzhou 510640, China) | 2001 | Acta Mechanica Solida Sinica2001，14，2： | 0 |
| 4 | Selective photocatalytic aerobic oxidative cleavage of lignin C–O bonds over sodium lignosulfonate modified Fe_(3)O_(4)/TiO_(2)显示文摘Lignocellulose shows significantly potential in sustainable conversion to high-quality fuel and valueadded chemicals with the demands for realizing the rapid cycle of carbon resources and helping to reach carbon neutrality in nature.Selective tailoring of α-O-4,β-O-4,etc.linkages in lignin has always been viewed as 'death blow' for its depolymerization.Herein,novel sodium lignosulfonate(SL) modified Fe_(3)O_(4)/TiO_(2)(SL-Fe_(3)O_(4)/TiO_(2)) spherical particles have been developed and used as catalysts for selectively photocatalytic oxidative cleavage of organosolv lignin.As expected,80% selective conversion of lignin in C2-C4 esters has been achieved,while C-O bonds in lignin model compounds can be effectively cleaved.Other than normal hydroxyl radical-mediated photocatalytic depolymerization of lignin over TiO_(2)-based materials,in this contribution,mechanism studies indicate that photogenerated holes and superoxide anion radicals are main active species,which trigger the cleavage of α/β-O-4 bond,and the isotopelabeling study confirms the crucial factor of C_β-H dehydrogenation in cleavage of β-O-4 bonds. | Kejia Wu Jinrong Liang Sijie Liu Yimin Huang Minglong Cao Qiang Zeng Xuehui Li | 2023 | Journal of Energy Chemistry2023，，9： | 0 |
| 5 | STUDY ON TENSILE FAILURE MECHANISM AND HYBRID EFFECT OF INTRAPLY HYBRID COMPOSITES显示文摘The random critical-core model is adapted to investigate the tensile failure mech-anism and hybrid effect of unidirectionally arrayed hybrid composites with alternating low andhigh elongation fibers.By utilizing the model in conjunction with the results of the stress con-centration analysis in which the interfacial damage between fiber and matrix is considered,amicroscopic statistical analysis of both the first failure and ultimate failure of hybrids is per-formed.The variations of the first failure strain,the ultimate failure strain and the hybrid effectas the interfacial shear strength are obtained quantitatively.The concept of the hybrid effect forstrains has been clarified.The present results are compared with available experiment data anda reasonable agreement is found between the analytical predictions and the experimental results. | Zeng Qingdun Lin Xuehui | 2003 | Acta Mechanica Solida Sinica2003，16，1： | 0 |
| 6 | Radical and(photo)electron transfer induced mechanisms for lignin photo-and electro-catalytic depolymerization显示文摘As one of the three major components of woody biomass,lignin is a kind of natural organic polymer and the only abundant natural renewable resource with aromatic nucleus.Chemical catalysis induced depolymerization is an important and effective approach for lignin utilization.In particular,photocatalysis and electrocatalysis show great potential in accurately activating C-O/C-C bonds,which is a critical point of selective cleavage of lignin.In this contribution,we focus on radical and(photo)electron transfer induced reaction mechanisms of the photo(electro)catalytic depolymerization of lignin.Primarily,the general situation of Carbon-centered radicals and active oxygen species mediated lignin conversion has been discussed.Then the mechanisms for(photo)electron transfer mediated lignin depolymerization have been summarized.At the end of this review,the challenges and opportunities of photo(electro)catalysis in the applications of lignin valorization have been forecasted. | Kejia Wu Minglong Cao Qiang Zeng Xuehui Li | 2023 | Green Energy & Environment2023，8，2： | 0 |
| 7 | Synthesis and fluorescent properties of quinoxaline derived ionic liquids显示文摘Ionic liquids(ILs) have attracted increasing attention since last few decades due to their high molecular design abilities and wide applications in different fields.In this study,four novel fluorescent isoquinolino [2,1-a]quinoxalin-5-ium ILs were designed and synthesized via a two-step process including a simple dual Schiff’s base formation and a subsequent [RhCp*Cl_(2)]_(2)-catalyzed oxidative C-H activation/annulation reaction.The as-synthesized ILs were extensively characterized using FT-IR,~1 H-NMR,^(13)C-NMR,^(19)F-NMR,HSQC-NMR,HMBC-NMR and HR-MS.Their photophysical properties were determined by steady-state fluorescence spectroscopy.The results demonstrate that all these ILs showed dual or triple emissions,large stokes shift(90 nm) and mechanochromic behaviors.Basing on solvatochromism and titration experiments,it is thought that the emission bands of the ILs are raised from their local excited states,charge transfer states or excited state proton transfer of cations,while the substitute effect of these quinoxaline derived ILs on their stokes shifts is negligible. | Jiaqi Wu Lei Zhang Jinxing Long Qiang Zeng Biaolin Yin Xuehui Li | 2022 | Green Energy & Environment2022，7，5： | 0 |
| 8 | Role of methoxy and C_(α)-based substituents in electrochemical oxidation mechanisms and bond cleavage selectivity of β-O-4 lignin model compounds显示文摘In order to better understand the specific substituent effects on the electrochemical oxidation process of β-O-4 bond, a series of methoxyphenyl type β-O-4 dimer model compounds with different localized methoxyl groups, including 2-(2-methoxyphenoxy)-1-phenylethanone, 2-(2-methoxyphenoxy)-1-phenylethanol, 2-(2-methoxyphenoxy)-1-(4-methoxyphenyl)ethanone, 2-(2-methoxyphenoxy)-1-(4-methoxyphenyl)ethanol, 2-(2,6-dimethoxyphenoxy)-1-(4-methoxyphenyl)ethanone, 2-(2,6-dimethoxyphenoxy)-1-(4-methoxyphenyl)ethanol have been selected and their electrochemical properties have been studied experimentally by cyclic voltammetry, and FT-IR spectroelectrochemistry. Combining with electrolysis products distribution analysis and density functional theory calculations, oxidation mechanisms of all six model dimers have been explored. In particular, a total effect from substituents of both para-methoxy(on the aryl ring closing to Cα) and Cα-OH on the oxidation mechanisms has been clearly observed, showing a significant selectivity on the Cα-Cβbond cleavage induced by electrochemical oxidations. | Yang Zhou Qiang Zeng Hongyan He Kejia Wu Fuqiao Liu Xuehui Li | 2024 | Green Energy & Environment2024，9，1： | 0 |
