| 1 | 基于ZY3 DEM和SRTM DEM的北京平原区地貌特征探析显示文摘研究区主要包括北京东部的通州、平谷、顺义、燕郊、大厂和三河,位于华北沉降带北部、阴山东西向构造带南缘。该区地势总体上西北略高,东南略低,为大型缓倾斜平原,地形不仅受本区内北东向断裂的影响,还受北西向断裂的影响。资源三号卫星立体影像(ZY3)DEM和NASA航天飞机雷达地形任务(SRTM)DEM在北京地区地貌特征研究中显示出了许多优于其他DEM的优势。文章利用包括水系偏转、河长坡降指标(SL)、面积-高程积分值(HI)、等值线分级色彩显示和地形粗糙度等几种地形参数,分析了地形特征与断层构造活动性的关系。水系的右旋偏转证实了该区北东向断裂的右旋走滑活动,如夏垫断裂和其他相邻断裂。SL指数表明,河床纵剖面在横跨断层处均是陡坡;HI的高值主要集中在南口-孙河断裂与该区其他北东向断裂的交汇处,夏垫断裂的中段,以及香河县西北部,反映了该区强烈的构造活动,同时也反映出可能存在隐伏断层。另外,研究表明,面积、高程积分值的高值区与低值区相邻衔接处,往往是地震危险性较大的地方。此外,平原区相同值域的面积-高程积分所反映的构造活动强度应该与山区不同,因此地貌演化阶段划分标准也应与山区有所不同。等值线分级色彩显示对地形变化非常敏感,当与已识别的断层重叠时,大部分地形突变的地方都与断层活动有关。地形粗糙度分析显示不同断裂带的地形粗糙度与断裂活动强度呈正相关关系。 | 王艳萍 Pinliang Dong 廖顺宝 | 2019 | 第四纪研究2019,39,5: | 2 |

| 3 | Hydroxyapatite-modified micro/nanostructured titania surfaces with different crystalline phases for osteoblast regulation显示文摘Surface structures and physicochemical properties critically influence osseointegration of titanium(Ti)implants.Previous studies have shown that the surface with both micro-and nanoscale roughness may provide multiple features comparable to cell dimensions and thus efficiently regulate cell-material interaction.However,less attention has been made to further optimize the physicochemical properties(e.g.,crystalline phase)and to further improve the bioactivity of micro/nanostructured surfaces.Herein,micro/nanostructured titania surfaces with different crystalline phases(amorphous,anatase and anatase/rutile)were prepared and hydroxyapatite(HA)nanorods were deposited onto the as-prepared surfaces by a spin-assisted layer-by-layer assembly method without greatly altering the initial multi-scale morphology and wettability.The effects of crystalline phase,chemical composition and wettability on osteoblast response were investigated.It is noted that all the micro/nanostructured surfaces with/without HA modification presented superamphiphilic.The activities of MC3T3-E1 cells suggested that the proliferation trend on the micro/nanostructured surfaces was greatly influenced by different crystalline phases,and the highest proliferation rate was obtained on the anatase/rutile surface,followed by the anatase;but the cell differentiation and extracellular matrix mineralization were almost the same among them.After ultrathin HA modification on the micro/nanostructured surfaces with different crystalline phases,it exhibited similar proliferation trend as the original surfaces;however,the cell differentiation and extracellular matrix mineralization were significantly improved.The results indicate that the introduction of ultrathin HA to the micro/nanostructured surfaces with optimized crystalline phase benefits cell proliferation,differentiation and maturation,which suggests a favorable biomimetic microenvironment and provides the potential for enhanced implant osseointegration in vivo. | Pinliang Jiang Yanmei Zhang Ren Hu Xiankuan Wang Yuekun Lai Gang Rui Changjian Lin | 2021 | Bioactive Materials2021,6,4: | 2 |
| 4 | Advanced surface engineering of titanium materials for biomedical applications:From static modification to dynamic responsive regulation显示文摘Titanium(Ti)and its alloys have been widely used as orthopedic implants,because of their favorable mechanical properties,corrosion resistance and biocompatibility.Despite their significant success in various clinical applications,the probability of failure,degradation and revision is undesirably high,especially for the patients with low bone density,insufficient quantity of bone or osteoporosis,which renders the studies on surface modification of Ti still active to further improve clinical results.It is discerned that surface physicochemical properties directly influence and even control the dynamic interaction that subsequently determines the success or rejection of orthopedic implants.Therefore,it is crucial to endow bulk materials with specific surface properties of high bioactivity that can be performed by surface modification to realize the osseointegration.This article first reviews surface characteristics of Ti materials and various conventional surface modification techniques involving mechanical,physical and chemical treatments based on the formation mechanism of the modified coatings.Such conventional methods are able to improve bioactivity of Ti implants,but the surfaces with static state cannot respond to the dynamic biological cascades from the living cells and tissues.Hence,beyond traditional static design,dynamic responsive avenues are then emerging.The dynamic stimuli sources for surface functionalization can originate from environmental triggers or physiological triggers.In short,this review surveys recent developments in the surface engineering of Ti materials,with a specific emphasis on advances in static to dynamic functionality,which provides perspectives for improving bioactivity and biocompatibility of Ti implants. | Pinliang Jiang Yanmei Zhang Ren Hu Bin Shi Lihai Zhang Qiaoling Huang Yun Yang Peifu Tang Changjian Lin | 2023 | Bioactive Materials2023,,9: | 2 |

| 10 | Enhanced growth of crystalline-amorphous core-shell silicon nanowires by catalytic thermal CVD using in situ generated tin catalyst显示文摘In this work,we prepared silicon nanowires(Si NWs) on both fluorine-doped SnO 2(FTO) coated glass substrate and common glass substrate by catalytic thermal chemical vapor deposition(CVD) using indium film as the catalyst.It is confirmed that indium can catalyze the growth of Si NWs.More importantly,we found that tin generated in situ from the reduction of SnO 2 by indium can act as catalyst,which greatly enhances the growth of Si NWs on FTO substrate.The obtained Si NWs have a uniform crystalline-amorphous core-shell structure that is formed via vapor-liquid-solid and vapor-solid growth of silicon sequentially.This work provides a strategy to prepare Si NWs in high yield by catalytic thermal CVD using the low melting point metal catalysts. | CHENG ShiMin REN Tong YING PinLiang YU Rui ZHANG WenHua ZHANG Jian LI Can | 2012 | Science China Chemistry2012,55,12: | 1 |

| 16 | Cell osteogenic bioactivity mediated precisely by varying scaled micro-pits on ordered micro/nano hierarchical structures of titanium显示文摘Hierarchical surface structures with micro–nano scale play a crucial role in regulation of cell proliferation and osteogenic differentiation.It has been proven that cells are extremely sensitive to the nanoscaled structure and show multifarious phenotypes.Though a vital function of microstructure on osseointegration has been confirmed,the cell performances response to different microscaled structure is needed to be further dissected and in depth understood.In this work,the ordered micro–nano hierarchical structures with varying micro-scaled pits were precisely fabricated on titanium successfully by the combination of electrochemical,chemical etching and anodization as well.In vitro systematical assessments indicated that the micro–nano multilevel structures on titanium exhibited excellent cells adhesion and spreading ability,as well as steerable proliferation and osteogenic differentiation behaviors.It is shown that smaller micro-pits and lower roughness of the hierarchical structures enabled faster cell propagation.Despite cell growth was delayed on micro–nano titanium with relatively larger cell-match-size micro-pits and roughness,osteogenic-specific genes were significantly elevated.Furthermore,the alkaline phosphatase activity,collagen secretion and extracellular matrix mineralization of MC3T3-E1 on multiscaled titanium were suppressed by a large margin after adding IWP-2(an inhibitor of Wnt/b-catenin signal pathway),indicating this pathway played a crucial part in cell osteogenic differentiation modulated by micro–nano structures. | Yanmei Zhang Xiankuan Wang Yaxian Li Jianhe Liang Pinliang Jiang Qiaoling Huang Yun Yang Hongping Duan Xiang Dong Gang Rui Changjian Lin | 2022 | Regenerative Biomaterials2022,9,1: | 1 |
| 17 | Using the Lonsdorf model for estimating habitat loss and fragmentation effects on pollination service显示文摘One of the most important issues related to landscape ecology and ecosystem services is finding the pattern of habitat patches that offers the highest pollination in agricultural landscapes.In this regard,two processes of habitat loss and fragmentation strongly affect the relationship between pollination and the pattern of habitat patches.In the present study,we aimed to examine the effects of habitat loss and fragmentation on pollination separately.For this purpose,first,we generated different simulated agricultural landscapes,including two habitats of forest and agriculture.Then,according to the Lonsdorf model,we estimated the potential of the simulated landscapes in providing pollination in different scenarios.Finally,using statistical models,we estimated the effects of habitat loss and fragmentation on pollination at the landscape and farm levels.Our results showed that the effects of habitat loss and fragmentation on pollination were completely different at the landscape and farm levels.At the landscape level,fragmentation negatively affected pollination,but at the farm level,the maximum pollination rate was observed in the landscapes with a high degree of fragmentation.Regarding the habitat loss effects,our results showed that pollination decreased linearly at the landscape level as habitat amount decreased,but at the farm level,it decreased exponentially.The present study considered the level of analysis(i.e.,landscape and farm levels)as a critical factor affecting pollination changes caused by fragmentation.We showed that using the Lonsdorf model could lead to confusing results for the landscape ecologists and alert farmers who want to reduce the adverse effects of fragmentation on their products by creating new forest patches.Therefore,agriculturalists and landscape ecologists should consider that the pollination rate at the landscape and farm levels is completely different according to the model and provide contradictory results about the process of habitat loss effects on pollination. | Ehsan Rahimi Shahindokht Barghjelveh Pinliang Dong | 2021 | Ecological Processes2021,10,1: | 1 |
