Electro-optical dual modulation on resistive switching behavior in BaTiO3/BiFeO3/TiO2 heterojunction

引用

Chinese Physics B 2019年第12期28卷 292-297页

作者： Jia-Jia Zhao Jin-Shuai Zhang Feng Zhang Wei Wang hai-rong he Wang-Yang Cai Jin Wang School of Computer and Communication Engineering Changsha University of Science and TechnologyChangsha 140114China School of Engineering and Materials Science Queen Mary University of London E14NSUnited Kingdom Peking University Shenzhen Graduate School Shenzhen 518055China

The novel BaTiO3/BiFeO3/TiO2 multilayer heterojunction is prepared on a fluorine-doped tinoxide(FTO) substrate by the sol–gel method. The results indicate that the Pt/Ba TiO3/BiFeO3/TiO2/FTO heterojunction exhibits stable bipolar resistive switching characteristic, good retention performance, and reversal characteristic. Under different pulse voltages and light fields, four stable resistance states can also be realized. The analysis shows that the main conduction mechanism of the resistive switching characteristic of the heterojunction is space charge limited current(SCLC) effect. After the comprehensive analysis of the band diagram and the P–E ferroelectric property of the multilayer heterojunction, we can deduce that the SCLC is formed by the effect of the oxygen vacancy which is controlled by ferroelectric polarizationmodulated change of interfacial barrier. And the effective photo-generated carrier also plays a regulatory role in resistance state(RS), which is formed by the double ferroelectric layer Ba TiO3/BiFeO3 under different light fields. This research is of potential application values for developing the multi-state non-volatile resistance random access memory(RRAM) devices based on ferroelectric materials.

引用

Acta Pharmacologica Sinica 2004年第7期 9-14页

作者： Hong-hong YAO, Jian-hua DING, hai-rong he, Gang HU2 Department of Pharmacologyand Neurobiology, Nanjing Medical University, Nanjing 210029, China

AIM: To investigate the effect of 1-methyl-4-phenylpyridinium (MPP+) on the glutamate uptake into cultured C6 glioma cells. METHODS: The glutamate uptake into C6 glioma cells was measured by radio-ligand binding assay method. The effect of MPP+ on the morphology of C6 glioma cells was observed under phase contrast microscopy; apoptosis of C6 glioma cells were measured by FITC-labeled Annexin V staining and flow cytometry. Cell viability was measured by MTT method. RESULTS: MPP+inhibited glutamate uptake into C6 glioma cells. However, MPP+ failed to induce any morphological changes of C6 glioma cells, and exposure to MPP+ had no effect on the viability and the apoptotic percentage of C6 glioma cells. Incubation with 12-O-tetradecanoylphorbol -13-acetate (TPA), a protein kinase C activator, caused a significant increase in glutamate uptake and completely reversed MPP+-induced inhibitory effect on glutamate uptake. CONCLUSION: The present results indicate that glutamate transporters mayhave important pathogeneticimplications in Parkinson disease. MPP+-inducedinhibition ofglutamate uptake was due to the dysfunction of glutamate transporters; TPA enhanced glutamate uptake and completely reversed the inhibitory effect of MPP+.

作者： Jin Yang Qing-Qing Liu hai-rong he hai-Sheng You Zhen-Yu Pan Jun Lyu Clinical Research Center The First Affiliated Hospital of Xi’an Jiaotong University Xi’an Shaanxi 710049 China School of Public health Xi’an Jiaotong University Health Science Center Xi’an Shaanxi 700049 China Department of Pharmacy The First Affiliated Hospital Xi’an Jiaotong University Xi’an Shaanxi 710049 China Department of Pharmacy The Affiliated Children Hospital of Xi’an Jiaotong University Xi’an Shaanxi 710049 China Institute of Evidence-Based Medicine and Knowledge Translation Henan University Kaifeng 475001 China

Background: Follicular variant papillary thyroid carcinoma (FVPTC) is the most common subset of papillary carcinoma. Lymph-node metastasis (LNM) is one of the main predictors of survival in PTC patients, but we found few data related to the correlation between LNM and FVPTC. We therefore aimed to elucidate the relationship between LNM and survival in patients with FVPTC. Methods: Logistic regression models were used to determine the factors associated with LNM. The Cox proportional-hazards model was applied to assess the association between LNM and disease-specific mortality. Kaplan-Meier survival analysis and the log-rank test were used to estimate the disease-specific survival rates in patients with and without LNM. Results: In total, 1418 FVPTC patients were identified. The multivariate logistic regression model showed that age, female sex, being married, tumor size > 4cm and extrathyroidal extension and radiation were predictors of LNM. The multivariate Cox regression model showed that age, multifocality and radiation were risk factors of diseasespecific mortality. Especially, LNM (p=0.271) did not independently predict disease-specific mortality. Kaplan-Meier survival analysis and the log-rank method also showed that LNM did not impact survival in FVPTC (p=0.235). Conclusion: Using data in the SEER database from 2004 to 2014, and after multivariate model correction, we found that age, multifocality and radiation were strongly related to disease-specific mortality. It is worth noting that LNM does not impact the survival of FVPTC patients.

Enantioselective reductive conjugate alkenylation of α,β-enones with keto alkenyl acetates by nickel catalysis

引用

Science China Chemistry 2025年第1期68卷 157-162页

作者： rong-De he Yun-Lei Luo Qiu-Quan Pan Qi-Wei Yao Xing-Zhong Shu State Key Laboratory of Applied Organic Chemistry College of Chemistry and Chemical Engineering Lanzhou University

Reactions involving alkenyl acetates offer cost-effective and environmentally friendly routes for alkene synthesis, yet their asymmetric variant remains elusive. Concurrently, asymmetric conjugate alkenylation predominantly centered on nucleophilic addition using alkenyl–M. This manuscript presents an asymmetric reductive conjugate alkenylation reaction involving alkenyl acetates. The method facilitates the enantioselective addition of keto alkenyl groups to α,β-enones, resulting in the formation of unsaturated diketones—a class of useful structural motifs that are challenging to access otherwise. The use of electron-rich Pyroxy ligand is essential for achieving both high reaction efficiency and enantioselectivity.

Reconstructing forest and grassland cover changes in China over the past millennium

Science China Earth Sciences 2025年第1期68卷 94-110页

作者： Fanneng he Fan YANG Yafei WANG Key Laboratory of Land Surface Pattern and Simulation Institute of Geographic Sciences and Natural Resources Research Chinese Academy of Sciences Key Research Institute of Yellow River Civilization and Sustainable Development Henan University University of Chinese Academy of Sciences

Historical forest and grassland cover changes not only are critical indicators for quantifying ecological and environmental change processes but also serve as fundamental data for long-term climate change simulations and terrestrial ecosystem carbon emission assessments. However, because of limitations in historical data, quantitative estimations and spatially gridded reconstructions of these changes remain challenging, necessitating further methodological exploration. This study focused on China's present-day land area over the past millennium, objectively capturing the characteristics and drivers of forest and grassland cover changes. On this basis, using the forest transition theory and the space-for-time substitution method, we depicted the historical deforestation process as an inverted “S” curve and developed a model to reconstruct historical forest area changes based on the functional relationship between the forest area and population size dynamics. Subsequently, a gridded forest allocation model was established on the basis of deforestation tendencies. For the grassland cover, we implemented regionspecific methods, such as the cropland area deduction method and the habitat constraint method, to quantitatively reconstruct historical changes. Consequently, we obtained provincial forest and grassland area changes over the past millennium and mapped 10-km-resolution gridded data of forest and grassland cover. The results indicated the following.(1) The methods developed using population data as a proxy objectively reproduced the spatiotemporal evolution of forest and grassland cover in China over the past millennium. These feasible methods offer a novel pathway for the quantitative reconstruction of historical forest and grassland cover changes.(2) The data indicated that China's forest area generally decreased over the past millennium, characterized by a “decrease-then-increase” pattern. The forest area experienced three distinct phases: a slow decline(AD 1000

Malignant neoplasms consistently pose a significant threat to global public health [1,2]. In recent years, immunotherapy has demonstrated remarkable clinical success; however, its efficacy is limited by the scarcity of immune cell infiltration within tumor microenvironments. Cell pyroptosis, a gasdermin-mediated process characterized by cellular swelling,rupture, and the release of intracellular contents such as IL-1β, IL-18, ATP, HMGB1, plays a crucial role in this context[3,4].
