| 1 | Study on the ore-forming and ore-controlling structure of the Mujicun Cu (Mo) ore deposit, Hebei Province, China显示文摘The Mujicun Cu (Mo) ore deposit at Laiyuan, Hebei Province, is a currently proven large-sized Cu (Mo) polymetallic ore deposit and it is located in the second-ordered fault depression basin of the ditachment belt on the hanging-wall on the western side at the juncture of the Laiyuan dumbell-shaped complex in the northern part of the Fuping mantle-branch structure. Metallogenesis is controlled by diorite porphyrite in intrusive relation with the fault depression basin and other relevant fault structure systems and intenstive wall-rock alteration zones. This study, in conjunction with the most recent exploration data, analyzed the geological background of metallogenesis of this deposit, summaried the geological characteristics of typical ore deposits, determined the alteration zonation of the deposit, investigated regional metallogenesis and the genesis of typical ore deposits, discussed the regional ore-forming and ore-controlling structures, and generalized the regional ore-controlling model and metallogenic model of the deposit. It is considered that the Mujicun porphry Cu (Mo) deposit, the Tieling, Futuyu, Xiaoligou and other skarn-type Fe-Cu deposits and the He'ergou hydrothermal-type Pb-Zn-Ag deposit jointly constitute a three-in-one polymetallic orefield, with the characteristics of typical metallogenic series. | NIU Shuyin MA Guoxi CHEN Zhikuan WANG Baode CHEN Lijing SUN Aiqun MA Xiaofeng ZHANG Jianzhen MA Baojun CHEN Chao LU Hongpeng | 2012 | Chinese Journal Of Geochemistry2012，31，1： | 2 |
| 2 | A spike-trimer protein-based tetravalent COVID-19 vaccine elicits enhanced breadth of neutralization against SARS-CoV-2 Omicron subvariants and other variants显示文摘Multivalent vaccines combining crucial mutations from phylogenetically divergent variants could be an effective approach to defend against existing and future SARS-Co V-2 variants.In this study,we developed a tetravalent COVID-19 vaccine SCTV01E,based on the trimeric Spike protein of SARS-Co V-2 variants Alpha,Beta,Delta,and Omicron BA.1,with a squalenebased oil-in-water adjuvant SCT-VA02B.In the immunogenicity studies in na?ve BALB/c and C57BL/6J mice,SCTV01E exhibited the most favorable immunogenic characteristics to induce balanced and broad-spectrum neutralizing potencies against pre-Omicron variants(D614G,Alpha,Beta,and Delta)and newly emerging Omicron subvariants(BA.1,BA.1.1,BA.2,BA.3,and BA.4/5).Booster studies in C57BL/6J mice previously immunized with D614G monovalent vaccine demonstrated superior neutralizing capacities of SCTV01E against Omicron subvariants,compared with the D614G booster regimen.Furthermore,SCTV01E vaccination elicited na?ve and central memory T cell responses to SARS-Co V-2 ancestral strain and Omicron spike peptides.Together,our comprehensive immunogenicity evaluation results indicate that SCTV01E could become an important COVID-19 vaccine platform to combat surging infections caused by the highly immune evasive BA.4/5 variants.SCTV01E is currently being studied in a head-to-head immunogenicity comparison phase 3 clinical study with inactivated and m RNA vaccines(NCT05323461). | Rui Wang Hongpeng Huang Chulin Yu Chunyun Sun Juan Ma Desheng Kong Yalong Lin Dandan Zhao Shaozheng Zhou Jianbo Lu Sai Cao Yanjing Zhang Chunxia Luo Xuefeng Li Yang Wang Liangzhi Xie | 2023 | Science China(Life Sciences)2023，66，8： | 1 |

| 5 | Optimal dose of zinc supplementation for preventing aluminum-induced neurotoxicity in rats显示文摘Zinc supplementation can help maintain learning and memory function in rodents.In this study,we hypothesized that zinc supplementation could antagonize the neurotoxicity induced by aluminum in rats.Animals were fed a diet containing different doses of zinc(50,100,200 mg/kg)for 9 weeks,and orally administered aluminum chloride(300 mg/kg daily)from the third week for 7 consecutive weeks.Open-field behavioral test results showed that the number of rearings in the group given the100 mg/kg zinc supplement was significantly increased compared with the group given the50 mg/kg zinc supplement.Malondialdehyde content in the cerebrum was significantly decreased,while dopamine and 5-hydroxytryptamine levels were increased in the groups given the diet supplemented with 100 and 200 mg/kg zinc,compared with the group given the diet supplemented with50 mg/kg zinc.The acetylcholinesterase activity in the cerebrum was significantly decreased in the group given the 100 mg/kg zinc supplement.Hematoxylin-eosin staining revealed evident pathological damage in the hippocampus of rats in the group given the diet supplemented with 50 mg/kg zinc,but the damage was attenuated in the groups given the diet supplemented with 100 and200 mg/kg zinc.Our findings suggest that zinc is a potential neuroprotective agent against aluminum-induced neurotoxicity in rats,and the optimal dosages are 100 and 200 mg/kg. | Hao Lu Jianyang Hu Jing Li Wei Pang Yandan Hu Hongpeng Yang Wenjie Li Chengyu Huang Mingman Zhang Yugang Jiang | 2013 | Neural Regeneration Research2013，8，29： | 0 |
| 6 | Carbon dots and carbon nitride composite for photocatalytic removal of uranium under air atmosphere显示文摘Photocatalytic removal of uranium has attracted much attention in nuclear wastewater treatment and it is highly needed to develop functional photocatalyst with excellent removal performance.In this work,seven kinds of carbon dots/carbon nitride(CDs/CN)composites were synthesized and Ser CDs/CN with the best photo-assisted uranium removal performance was screened out.It was found that the introduction of CDs could bring in higher photocurrent density,lower interfacial charge transfer impedance and narrower band gap,resulting in a much-improved removal performance.SerCDs/CN had shown a removal capacity as high as 1690 mg/g and the reaction could be operated under air atmosphere which is promising in real application. | Hongpeng Li Qi Qing Liyuan Zheng Lan Xie Zhiqiang Gan Liqin Huang Shuang Liu Zhe Wang Yuexiang Lu Jing Chen | 2022 | Chinese Chemical Letters2022，33，7： | 0 |
| 7 | Microplasma electrochemistry(MIPEC)strategy for accelerating the synthesis of metal organic frameworks at room temperature显示文摘Metal organic frameworks(MOFs) are a kind of promising materials in many applications,while the fast and controllable synthesis of MOFs is still challenging.Here,taking HKUST-1 as illustration,a microplasma electrochemistry(MIPEC) strategy was developed to accelerate the synthesis process of MOFs with micro-plasma acting as cathode.Treating the HKUST-1 precursor solution with micro-plasma cathode could not only transfer the electrons into the solution leading to the deprotonation effect,but also generate radical species to trigger and accelerate the nucleation and growth of MOFs at the plasmaliquid interface.Thus,uniform and nanosize MOFs could be prepared within minutes.The obtained MOFs show similar excellent uranium adsorption properties compared with those obtained by other method,with a highly adsorption capability of uranium with 550 mg/g in minutes.The novel MIPEC strategy developed in this work provides an alternative for controllable synthesis of MOFs,and especially has potential application in accelerating traditional organic synthesis. | Guoyu Wei Yuexiang Lu Shuang Liu Hongpeng Li Xuegang Liu Gang Ye Jing Chen | 2021 | Chinese Chemical Letters2021，32，1： | 0 |
| 8 | Constructing a high concentration CuO/CeO_(2) interface for complete oxidation of toluene:The fantastic application of spatial confinement strategy显示文摘In this paper,CeO_(2) substrate was prepared by the sol-gel method,further CuO was introduced by adding the copper complexes with chelating agents into the sol-gel precursors of CeO_(2),in which different chelating agents(β-cyclodextrin,glucose and trimesic acid)were tried.This synthesis method helps the CuO species to disperse very uniformly in the CeO_(2) substrates.When the amount of copper oxide is up to33 mol%,the CuO/CeO_(2) samples can still maintain a highly dispersed state.The CeO_(2) and CuO/CeO_(2)samples were characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),transmission electron microscopy(TEM),X-ray photoelectron spectroscopy(XPS),temperature-programmed reduction of hydrogen(H_(2)-TPR),temperature-programed desorption(O_(2)-TPD),etc.It is found that the CuO/CeO_(2) catalyst prepared byβ-cyclodextrin(βCuO/CeO_(2)) exhibits better catalytic performance owing to the higher dispersion,higher specific surface area,more defects,more active Ce3+and Cu^(+) ions,more oxygen vacancies,more surface active oxygen,relatively better low temperature reducibility,and the exposed(110) active facets.In the condition of 1000×10-6toluene in air and WHSV=60000 mL/(g·h),the T90for toluene conversion is 227℃.The reaction mechanism of toluene catalytic oxidation over CeO_(2)andβCuO/CeO_(2) is discussed by the study of in-situ DRIFTS.This work affords a simple and efficient method for the synthesis of highly dispersed bimetal oxide catalysts with high contents. | Chao Wang Yan Li Huiao Liu Ziying Hu Xinhui Hao Hongpeng Jia Jing Chen Canzhong Lu | 2023 | Journal of Rare Earths2023，41，6： | 0 |
