Review of My Research Work on Ferroelectric Films and Si-Based Device Applications: Opportunity and Challenge

Ferroelectric materials have many interesting physical properties such as ferroelectricity, pyroelectricity, piezoelectricity, and opto-electricity, and applying ferroelectric materials in the forms of thin and thick films and integrating them on the silicon substrate as electronic and MEMS devices is a very attractive research area and challenging. In this paper, we report our research works on ferroelectric MEMS and ferroelectric films for electronic device applications. Pyroelectric thin film infrared sensors have been made, characterized, and a 32×32 array with its size of 1cm×1cm has been obtained on Si membrane. Ferroelectric thin films in amorphous phase have been applied to make silicon based hydrogen gas sensors with the metal/amorphous ferroelectric film/metal device structure, and its turn-on voltage of about 4.5V at ～1000 ppm in air is about 7 times of the best value reported in the literature. For the application of electron emission flat panel display, ferroelectric BST thin films with excess Ti concentrations have been coated on Si tips, the threshold voltage of those ferroelectric film coated tips has been reduced about one order from ～70 V/μm to 4～10 V/μm for different Ti concentrations, and however, the electron emission current density has been increased at least 3～4 order for those coated tips compared to that of the bare Si tips. To fulfill in the thickness gap between thin film of typical ～1 μm made by PVD/CVD and polished ceramic wafer of ～50 μm from the bulk, piezoelectric films with thickness in a range of 1～30 μm have been successfully deposited on Si substrate at a low temperature of 650oC by a novel hybridized deposition technique, and piezoelectric MEMS ultrasonic arrays have been very recently obtained with the sound pressure level up to ～120 dB. More detailed results will be presented and mechanisms will be discussed.

Journal News: Hartman and Spit’s Research Work, Published in American Journal of Climate Change, Has Been Cited by Top Journal Nature Geoscience

Capacity building is a key issue for the implementation of climate adaptation measures in urban planning processes. For successful capacity building, it is important to define the relevant stakeholders and tailor the adaptation strategies first to (the position of) these stakeholders and next to the specific urban conditions and issues. In addition, scientific insights and tools can be of assistance, and the use of climate maps can help to create a common language. Thomas Hartmann and Tejo Spit’s research work on capacity building was published in American Journal of Climate Change, 3, 245-252, 2014 [1]. In June 2015, Thomas Hartmann and Tejo Spit’s research work [1] was cited by Nature Geoscience as one of six important papers in the field of capacity building [2], in detail, please see: http://www.nature.com/ngeo/journal/v8/n7/full/ngeo2465.html.

Journal News: Osmar Pinto Jr. <i>et al</i>.’s Research Work, Published in American Journal of Climate Change, Has Been Reported by BBC News

The city of Manaus (Brazil) is located in the central part of the largest tropical forest in the world, the Amazon rainforest, and has a population of approximately 2 million inhabitants. Osmar Pinto Jr., Iara Regina Cardoso de Almeida Pinto, and Osmar P. Neto showed that the lightning activity in Manaus is larger than that in the regions around the city and it has been increasing in the last four decades with the increasing of the urban area of the city. These results suggest that these spatial and time variations are related to the Urban Heat Island effect, since it is believed that the Urban Heat Island effect influences thunderstorm formation and evolution and, in consequence, the lightning activity. Therefore, they suggest that the replacement of the forest by urban areas tends to increase the lightning activity in the Amazon region. These results were published in American Journal of Climate Change in December 2013 [1] 08D0C9EA79F9BACE118C8200AA004BA90B02000000080000000E0000005F005200650066003300390030003700300031003600360033000000 . In March 14, 2014, BBC News reported Osmar Pinto Jr. et al.’s results.

Journal News: Pinhas Alpert <i>et</i><i>al</i>.’s Research Work, Published in American Journal of Climate Change (AJCC), Has Been Reported Widely by the Media

Pinhas Alpert’s team studies recent decadal trends of aerosol optical depth (AOD) over megacities around the world by using three NASA space aerosol sensors: MODIS-Terra, MODIS-Aqua and MISR. Results from these three satellites clearly show a rise in air pollution levels in the megacities of the Middle East, India and North China (see Figure 1). At the same time, Alpert et al.’s study also reveals some positive trends. Megacities in Europe, northeastern United States and South-East Asia indicate a decrease in air pollution from 2002 to 2010 (see Figure 1). These cities have taken active steps to reduce the amount of contaminants in the air. Alpert hopes that these greener cities will serve as an example to the rest of the world, inspiring those who have yet to clean up their communities to push for environmental reforms.

运用唯物史观“推出有思想穿透力的精品力作”

中国特色社会主义进入新时代,党和国家高度重视历史学科建设发展,十分关心支持历史研究工作,明确了历史学科以及历史研究在党和国家事业发展中的重要地位和作用,为史学事业繁荣发展创造了极其难得的时代条件、文化环境和比较优势。习近平在关于历史科学的重要论述中提出“推出有思想穿透力的精品力作”的重要要求和目标指向,对于推动当代中国史学繁荣发展具有重要意义。推出有思想穿透力的史学精品力作,离不开唯物史观理论智慧的指引和启发。唯物史观理论和方法为史家主体“做”并“推出有思想穿透力的精品力作”提供了思想源泉和可靠路径。在当代,史学研究者至少可以从三个切入点着手:第一,找准研究的历史方位,立足问题载点,突出时代意识;第二,紧扣马克思主义社会经济形态理论,研究阐释中国特色社会主义的性质和道路;第三,坚持马克思主义总体史观和历史发展规律论,聚焦中国历史发展与世界历史进程。对于历史研究来说,史家主体不仅需要具有“求真”的品格和勇气,还要具备“致用”的胆识、确立“致用”的目标,守科学研究之正,创史学研究之新,做有思想穿透力的研究,出有思想穿透力的成果,努力造就中国史学繁荣发展的新局面。

Working Paper推进学术研究作用的实证研究——以金融经济领域为例

知识转化何以可能——基于社会工作实务课程的教育行动研究

在三轮社会工作实务课程的教学过程中,采用教育行动研究方法不断对教学内容进行改进,并围绕如何促进学生的知识转化展开探索。研究发现,学生在实践过程中的知识转化体现为个体认知层面的转化信念提升、实践操作层面的转化经验积累以及专业素养层面的转化价值重构等三重意涵。以实践经历为主线,应对实践难题是转化发生的开端,立足实践进行反思是促进转化的关键步骤,围绕实践展开讨论是实现转化的支持性要素,形成对实践的指引是完成转化的标志性环节。这其中蕴含了从调用或重构理论知识到建构生成、外化共享、内化整合实践知识的转化过程,也凸显了教学情境不同主体间良好关系的建立对于推动转化进程的重要意义。

数字孪生赋能的矿业实践教育自适应模式研究

行业数字化、信息化建设是当前我国矿业高质量发展的焦点。但长期以来,信息化、智能化专业人才的培养存在缺失。因此,研究数字孪生技术驱动下的矿业工程实践教育自适应模式对于推进国家矿业工程智能化与产教融合具有重要意义。本研究完成了以下工作:首先,解析矿业工程实践、数字孪生和自适应模式的内在关联,提出基于工业物联网的大数据管理框架(BDM)的信息集成与五维模型运作机制。其次,通过矿业工程实践教育体系要素的数据融合,结合Unity开发平台构建动态交互孪生系统的UI可视化,构建数字孪生仿真培训系统。最后,基于自适应模式开展人机交互与协同试验。结果表明,学员可以通过数字孪生显示的模型、动作、数据等信息获取矿山生产环节的实时状态,通过室内设备仿真操作与现场远程操控的误差在10%以下,且与井下工序重合度较高。在数字孪生技术驱动和交互共享机制支持下,有望通过信息有序管理和决策实现系统、精准的矿业工程专业人才智慧化培养模式。

Pain Assessment as a Tool in Back-to-Work Rehabilitation

The purpose of this study was to elucidate participant experiences with a way to use pain assessment as a tool in vocational rehabilitation and see if the process is perceived to be important for the rehabilitation process in a four-week lasting rehabilitation back to work program for people with chronic pain, mental illness and fatigue symptoms. Design: A qualitative study. Purposeful typical case sampling. Semi-structured qualitative interviews with rehabilitation back to work participants were thematic content analyzed. Setting: Interviews at the end of the 4th week of rehabilitation took place at a Rehabilitation Center in Central Norway. Subjects: Six women and four men aged 23 to 57 years, suffering from chronic pain and mild mental illness symptoms. Main outcome measure: This paper describes the participants’ experiences with pain mapping in back-to-work rehabilitation, used as a tool in a rehabilitation model for people suffering from chronic pain and mild mental illness. Results: The main topic was “empowered to insights”. The results illustrate a process where mapping tools were experienced relevant in the process of growing discovery of pain and ways of pain management. Pain assessment as a joint aid for both themselves and the staff provided a clearer pain understanding. Conclusion: Mapping as own activity, and cooperation with supportive personnel showing respect for patients’ own experiences, may promote empowerment, and further motivate own efforts and progress of the rehabilitation process.
