| 1 | Exploitation of Bi2O2Se/graphene van der Waals heterojunction for creating efficient photodetectors and short-channel field-effect transistors显示文摘The formation of heterojunction within solid-state devices enables them with eventually high performances,but provides a challenge for material synthesis and device fabrication because strict conditions such as lattice match are needed.Herein,we show a facile method to fabricate a van der Waals(vdW)heterojunction between two-dimensional(2D)bismuth oxyselenide(Bi2O2Se)and graphene,during which the graphene is directly transferred to the Bi2O2Se and served as a lowcontract-resistant electrode with small work function mismatch(~50 meV).As an optoelectronic device,the Bi2O2Se/graphene vdW heterojunction allows for the efficient sensing toward 1200-nm incident laser.Regarding the application of fieldeffect transistors(FETs),the short-channel(50 nm)sample can be synthesized by utilizing these two 2D materials(ie,channel:Bi2O2Se;drain/source terminal:graphene)and the n-type characteristic can be observed with the accordant field modulation.It is confirmed that we show a simple way to prepare the vdW heterojunction which is aiming to the high-performance applications among optoelectronics and FETs. | Congwei Tan Shipu Xu Zhenjun Tan Luzhao Sun Jinxiong Wu Tianran Li Hailin Peng | 2019 | InfoMat2019，1，3： | 8 |
| 2 | Rapamycin promotes Schwann cell migration and nerve growth factor secretion显示文摘Rapamycin, similar to FK506, can promote neural regeneration in vitro. We assumed that the mechanisms of action of rapamycin and FK506 in promoting peripheral nerve regeneration were similar. This study compared the effects of different concentrations of rapamycin and FK506 on Sc hwann cells and investigated effects and mechanisms of rapamycin on improving peripheral nerve regeneration. Results demonstrated that the lowest rapamycin concentration(1.53 nmol/L) more significantly promoted Schwann cell migration than the highest FK506 concentration(100 μmol/L). Rapamycin promoted the secretion of nerve growth factors and upregulated growth-associated protein 43 expression in Schwann cells, but did not significantly affect Schwann cell proliferation. Therefore, rapamycin has potential application in peripheral nerve regeneration therapy. | Fang Liu Haiwei Zhang Kaiming Zhang Xinyu Wang Shipu Li Yixia Yin | 2014 | Neural Regeneration Research2014，9，6： | 6 |
| 3 | Provenance analysis of surface sediments in the Holocene mud area of the southern coastal waters off Shandong Peninsula,China显示文摘The sedimentary record of mud areas is an important carrier of information on the Holocene evolution of marine environments. Based on fine interpretations of the shallow stratigraphic section data, a small mud deposit area has been found in the southern coastal waters off Shandong Peninsula. This mud area is mainly distributed in coastal waters north of Laoshantou to the vicinity of Rushan Estuary. Overall, it is parallel to the coastline and spreads in a banded pattern, gradually thinning from offshore to the sea. The isopach map of depth distribution is parallel with the shoreline, and the depocenter lies in coastal waters of the Aoshan Bay where the maximum thickness is up to 22.5 m. Accelerator mass spectrometry(AMS) ^(14)C dating shows that the mud area was formed in the Holocene. The test data of surface sediments from the mud area, including particle size, mineral characteristics, and rare earth element contents, are used in comparisons with the composition of materials from the major surrounding medium and small rivers flowing into the sea and the Huanghe(Yellow) River. In this paper, the sedimentary characteristics and provenance of the mud deposit area are discussed. The results show that the formation of this mud area resulted from the joint action of the Huanghe River and surrounding rivers flowing into the sea. | ZHANG Xiaobo BI Shipu ZHANG Yong YANG Yuan LIU Shanshan KONG Xianghuai LI Xiaoyue CHU Hongxian | 2016 | Acta Oceanologica Sinica2016，35，5： | 5 |

| 6 | Preparation of Nano-TiO_2 by Liquid Hydrolysis and Characterization of Its Antibacterial Activity显示文摘The nano-TiO2 particles were prepared by liquid hydrolysis method and characterized using XRD. Its antibacterial activity against two representative bacterial, Escherichia coli and Staphylococcus aureus, was also studied. The experimental results showed that the nano-TiO2 calcinated at 600-700 ℃ contained the obvious anatase phase and exerted excellent antibacterial activity. The feature of antibacterial activity of nanoTiO2 was non-strains specificity and exerted best antibacterial activity at concentration of 0.8 g/L. | 张启焕 YAN Xin 邵荣 DAI Honglian LI Shipu | 2014 | Journal of Wuhan University of Technology(Materials Science)2014，29，2： | 2 |

| 17 | Degradable PRGD/PDLLA/β-TCP/NGF composites promote differentiation and regulate gene expression in rat pheochromocytoma cells显示文摘In this study, we synthesized degradable PRGD/PDLLA/β-TCP/NGF composites to facilitate neuronal repair. To this end, we (1) examined the release of nerve growth factor (NGF) from the composites, (2) evaluated the differentiation status of the cells and (3) address how transcriptional activity may regulate the differentiation mechanism of these cells. NGF content was determined using enzyme-linked immunosorbent assay, while the cellular mRNA expression was examined by real-time PCR analysis. Our results indicated that NGF release was robust during the first 10 days and then stabilized at a lower level thereafter. Treatment of PC12 cells with the extract of the NGF-embedded composites induced the formation of neurites and, in some cases, net-like neurites. Analysis of the expression level of differentiation-related genes, such as TrkA, VGF, Rab1, GAP43 and β-tubulin Ⅱ, were significantly up-regulated. These findings suggest that these composites might be a suitable delivery system for growth factors like NGF that can be used to facilitate neuronal repair after injury. | QIU Tong YU Chang YAN QiongJiao LI ShiPu | 2013 | Chinese Science Bulletin2013，58，24： | 1 |
