| 1 | The compositions,sources,and size distribution of the dust storm from China in spring of 2000 and its impact on the global environment显示文摘The average mass concentration of the aerosols in Beijing during the dust storm in the spring of 2000 was -6000 μg · m-3, -30 times as high as that in the non-dust storm days. The enrichment factors of the pollution elements As, Sb and Se were higher than those in the non-dust storm days. This indicated that As, Sb and Se resulted from the pollution sources of those areas, through which the dust storm passed during their long-range transport, in addition to the local pollution sources in Beijing. The enrichment factors of the Pb, Zn, Cd and Cu were much less than those in the non-dust storm days, suggesting that the local pollution sources in Beijing area contributed to them mostly. The enrichment factors of elements Al, Fe, Sc, Mn, Na, Ni, Cr, V and Co were close to 1, showing that these elements originated from crust. The concentration of S in the dust storm was -10 μg · m-3,4 times as high as that in non-dust storm. S in the aerosols resulted from the adsorption of gaseous SO2 and the consequent | Guoshun Zhuang Jinghua Guo Hui Yuan Chengyi Zhao | 2001 | Chinese Science Bulletin2001，46，11： | 44 |
| 2 | Efficient conversion of benzene and syngas to toluene and xylene over ZnO-ZrO_(2)&H-ZSM-5 bifunctional catalysts显示文摘A series of ZnO-ZrO_(2) solid solutions with different Zn contents were synthesized by the urea coprecipitation method,which were coupled with H-ZSM-5 zeolite to form bifunctional catalysts.As a new benzene alkylation reagent,syngas was used instead of methanol to realize the efficient conversion of syngas and benzene into toluene and xylene.A suitable ratio of ZnO-ZrO_(2) led to the significant improvement in the catalytic performance,and a suitable amount of acid helped to increase the selectivity of toluene/xylene and reduce the selectivity of the by-products ethylbenzene and C^(9+) aromatics.The highest benzene conversion of 89.2%and toluene/xylene selectivity of 88.7%were achieved over 10%ZnO-ZrO_(2)&H-ZSM-5(Si/Al=23)at a pressure of 3 MPa and a temperature of 450℃.In addition,the effect of the zeolite framework structure on product distribution was examined.Similar to the molecular dynamics of aromatic hydrocarbons,H-ZSM-5 zeolites comprise 10-membered-ring pores,which are beneficial to the activation of benzene;hence,the conversion of benzene is higher.H-ZSM-35 and HMOR zeolites exhibited small eight-membered-ring channels,which were not conducive to the passage of benzene;hence,the by-product ethylbenzene exhibits a higher selectivity.The distance between the active centers of the bifunctional catalysts was the main factor affecting the catalytic performance,and the powder mixing method was more conducive to the conversion of syngas and benzene. | Xiao Zhao Xuan Shi Zhongshun Chen Long Xu Chengyi Dai Yazhou Zhang Xinwen Guo Dongyuan Yang Xiaoxun Ma | 2022 | Chinese Journal of Chemical Engineering2022，35，5： | 2 |
| 3 | A Soil Morphological Index for Paleosol Research显示文摘We developed a soil morphological index to quantitatively measure the degree ofpaleosol development. For its development, this index combined paleopedogenic features with tensoil macro- and micro-morphological properties from morphological descriptions of Potou and JiuZhoutai loess sections in the Loess Plateau of China. These ten properties are: rubification (colorhue and chroma), total texture (texture type, stickiness and plasticity), melanization (color value),microstructure, fine material (<0.01 mm), primary carbonate, biotite, fe(hydr)oxides, secondarycarbonate (micromorphology) and illuvial clay. Future study may reject some of these propertiesand add others. The index works well with the loess-paleosol sequences. The soil morphologicalindex successfully identifies paleosols and weak-paleosols. | LI Xuyong LI Baoguo GUO Zhengtang ZHAO Chengyi SHI Yuanchun 1 Commission for Integrated Survey of Natural Resources, CAS, Beijing 100101, China. 2 Department of Soil and Water, China Agricultural University, Beijing 100094, China 3 Institute of Geology, CAS, Beijing 100029, China 4 Institute of Xinjiang Ecology and Geography, CAS, Urumqi 830011.

| 4 | An iridium(Ⅲ)-palladium(Ⅱ) metal-organic cage for efficient mitochondria-targeted photodynamic therapy显示文摘An Ir8 Pd4-heteronuclear metal-organic cage(MOC-51)was assembled from bipodal metalloligand[Ir(ppy)2(qpy)(BF4)](qpy=4,4′:2′,2″:4″,4′′′-quaterpyridine;ppy-2-phenylpridine)with Pd(Ⅱ)salt.The cubic barrel shaped MOC shows one-photon and two-photon excited deep-red emission,as well as large singlet oxygen quantum yields under visible light irradiation,therefore exhibiting great potentials in organelles-targeted cell imaging and photodynamic therapy(PDT).Compared with the Ir(Ⅲ)metalloligand,the Ir8 Pd4-MOC showed less dark toxicity and higher mitochondria-targeting efficiency.The localization in mitochondria overco mes the limitation of short lifetime and diffusion distance of ROS in cell,thus improved PDT effect can be obtained in low light dose usage of the MOC.This study presents the first case of Ir-based metal-organic cages for bio-applications in successful integration of imaging diagnosis and photodynamic therapy. | Chaojie Li Yaping Wang Yulin Lu Jing Guo Chengyi Zhu Haozhe He Xiaohui Duan Mei Pan Chengyong Su | 2020 | Chinese Chemical Letters2020，31，5： | 1 |

| 8 | Fluoride-mediated nano-sized high-silica ZSM-5 as an ultrastable catalyst for methanol conversion to propylene显示文摘Fluoride mediated nano-sized ZSM-5(ZSM-5-F) with a high Si/Al ratio of 181 was fabricated using a seed-induction method and evaluated the catalysis of the methanol to propylene(MTP) reaction. High propylene selectivity(45%) was similar to ZSM-5-OH synthesized via a hydroxide route. However, ZSM-5-F showed much longer lifetime(305 h) compared with ZSM-5-OH(157 h) in spite of similar crystal size and aluminum content. Characterization by NH_3-TPD, Py-IR, OH-IR, SEM, TG-DTA, XRD and ~1H MAS NMR techniques indicated that the enhanced catalytic performance of ZSM-5-F is attributed to the fewer structural defects in the form of internal silanol groups and silanol nests. | Junjie Li Min Liu Xinwen Guo Chengyi Dai Chunshan Song | 2018 | Journal of Energy Chemistry2018，27，4： | 1 |
| 9 | Dielectrophoretic Assembly of Carbon Nanotube Chains in Aqueous Solution显示文摘Carbon nanotubes(CNTs)have generated remarkable interests in a wide range of research fields due to their excellent electri-cal properties.However,achieving the CNTs arrangement with high quality in a short time remains a challenge.Herein we studied the in-situ assembly of CNTs based on macroscopic dielectrophoresis by using a centimeter scale electrode,which overcome the limitation of small size in traditional method for manipulating nanoparticles.Ordered CNTs chains could be obtained under the action of alternating current dielectrophoresis by optimizing the voltage and frequency.Besides,the ordered chains were able to restore immediately upon powering up after being damaged.Furthermore,a CNTs chain was prepared for conducting the wet circuit and powering a LED,and different conductive patterns on the non-woven fabric were achieved by controlling the position of the electrodes in wet environment. | Dan Zhao Rui Liu Cheng Luo Yang Guo Chengyi Hou Qinghong Zhang Yaogang Li Wei Jia Hongzhi Wang | 2021 | Advanced Fiber Materials2021，3，5： | 1 |
| 10 | Multifaceted role of ferroptosis in cardiovascular disease显示文摘Ferroptosis is a newly identified form of non-apoptotic cell death characterised primarily by iron-dependent lipid peroxidation.It differs morphologically,biochemically,and genetically from other forms of cell death,such as apoptosis,autophagy,and necrosis.Although the molecular mechanism underlying ferroptosis remains unclear,multiple biological processes,such as iron metabolism,lipid peroxides,and systems,such as the glutathione system and the tetrahydrobiopterin/coenzyme Q10 system,appear to be involved.While the contribution of ferroptotic mechanisms to human diseases is not clear,recent studies have identified a number of ferroptosis-related genes.Cardiovascular diseases are the main cause of death globally.In this review,we outline the progress regarding the emerging role of ferroptosis in the pathogenesis of cardiac pathophysiological conditions and the association of ferroptosis with cardiomyopathy,myocardial ischemia-reperfusion injury,heart failure,and atherosclerosis.We further summarise newly discovered ferroptotic targets for the development of therapies for cardiovascular diseases.Finally,we discuss the current challenges and future research directions in cardiovascular disease treatments. | Chengyi Li Xiusong Zhu Juxian Chen Xiaoxi Xie Sijia Liang Xiu Liu Quan Gong Jiawei Guo | 2023 | Acta Biochimica et Biophysica Sinica2023，55，2： | 0 |

| 12 | Ferroptosis: a potential target for the treatment of atherosclerosis显示文摘Atherosclerosis(AS),the main contributor to acute cardiovascular events,such as myocardial infarction and ischemic stroke,is characterized by necrotic core formation and plaque instability induced by cell death.The mechanisms of cell death in AS have recently been identified and elucidated.Ferroptosis,a novel iron-dependent form of cell death,has been proven to participate in atherosclerotic progression by increasing endothelial reactive oxygen species(ROS)levels and lipid peroxidation.Furthermore,accumulated intracellular iron activates various signaling pathways or risk factors for AS,such as abnormal lipid metabolism,oxidative stress,and inflammation,which can eventually lead to the disordered function of macrophages,vascular smooth muscle cells,and vascular endothelial cells.However,the molecular pathways through which ferroptosis affects AS development and progression are not entirely understood.This review systematically summarizes the interactions between AS and ferroptosis and provides a feasible approach for inhibiting AS progression from the perspective of ferroptosis. | Chengyi Li Ran Liu Zhenyu Xiong Xue Bao Sijia Liang Haotian Zeng Wei Jin Quan Gong Lian Liu Jiawei Guo | 2024 | Acta Biochimica et Biophysica Sinica2024，56，3： | 0 |
| 13 | Transaldolase inhibits CD36 expression by modulating glutathione-p38 signaling,exerting protective effects against macrophage foam cell formation显示文摘In atherosclerosis,macrophage-derived foam cell formation is considered to be a hallmark of the pathological process;this occurs via the uptake of modified lipoproteins.In the present study,we aim to determine the role of transaldolase in foam cell formation and atherogenesis and reveal the mechanisms underlying its role.Bone marrow-derived macrophages(BMDMs)isolated from mice successfully form foam cells after treatment with oxidized low-density lipoprotein(80μg/mL).Elevated transaldolase levels in the foam cell model are assessed by quantitative polymerase chain reaction and western blot analysis.Transaldolase overexpression and knockdown in BMDMs are achieved via plasmid transfection and small interfering RNA technology,respectively.We find that transaldolase overexpression effectively attenuates,whereas transaldolase knockdown accelerates,macrophagederived foam cell formation through the inhibition or activation of cholesterol uptake mediated by the scavenger receptor cluster of differentiation 36(CD36)in a p38 mitogen-activated protein kinase(MAPK)signaling-dependent manner.Transaldolase-mediated glutathione(GSH)homeostasis is identified as the upstream regulator of p38 MAPK-mediated CD36-dependent cholesterol uptake in BMDMs.Transaldolase upregulates GSH production,thereby suppressing p38 activity and reducing the CD36 level,ultimately preventing foam cell formation and atherosclerosis.Thus,our findings indicate that the transaldolase-GSH-p38-CD36 axis may represent a promising therapeutic target for atherosclerosis. | Chengyi Li Zihao Song Pengyue Gao Wei Duan Xiu Liu Sijia Liang Quan Gong Jiawei Guo | 2023 | Acta Biochimica et Biophysica Sinica2023，55，9： | 0 |
