Abstract: 

Fiber-based optoelectronic technology is a new and cutting-edge technology developed in the past two decades. It is the result of infiltration and fusion of chemistry, physics, materials engineering, electronic engineering, optoelectronic engineering and textile engineering. The research object is optoelectronic fiber and its aggregate devices with sensing, actuation, communication, memory, self-adaptive, self-repairing, self-power and learning functions, which can perform the functions in a preprogramed manner. There are several ways to form fiber-based optoelectronic devices and systems. The fiber-based optoelectronic devices and systems formed by the combination of functional materials and fibers have many characteristics, such as flexibility, large deformation, light weight, large area, fashionable, comfort, and do not affect the activities and functions of people or machines, allowing long-term real time use. It has great potential advantages in engineering man-machine interfaces, large-area optoelectronic devices and systems, transportation, security, smart Internet of Things, smart cities, healthcare, wearable devices and systems. At the same time, safe green functional materials are employed, which can be processed at room temperature or under low temperature and non-vacuum conditions with mature machinery and processing technology. Multiphysics processes are involved in the manufacture and use of fiber-based optoelectronic devices, which typically involve large macroscopic deformation, mesoscopic fiber complexity, multiphase materials (including solids and gases), porous, multi-interface and so on. The unique structure and characteristics require the development of new characterization and analytical methods. In this talk, the related scientific problems and some solutions are proposed and discussed for the materials and structures of fiber-based and fiber assemblies (textile structure) optoelectronic devices, and their optical, electrical, thermal, mechanical properties and characterization.

Abstract: 

Correlation of two dimensional (2D) images using photorefractive materials are first reviewed.  The performance of a joint transform correlator based on photorefractive beam coupling is analyzed by determining the dependence of typical figures of merit such as the discrimination ratio, peak-to-correlation plane energy ratio, peak-to-noise ratio, etc. on the photorefractive gain coefficient and beam power ratio using typical reference and signal images.  Furthermore, correlation of three dimensional (3D) images is introduced as the correlation of their 2D digital holograms.  Critical figures of merit used for assessment of 2D correlation of images are applied to the correlation of holograms.  Figures of merit are applied for object height identification using digitally recorded holograms as the 2D images. Results show  the potential for accurate object height recognition based on obtained results corresponding to figures of merit as an assessment metric.

Moreover, I will demonstrate how artificial silk can be produced from spider-silk-like proteins designed based on our structures, how drug lead is identified based on structural and dynamic information, and why structural information is important for protein-based vaccine design.

Abstract: 

In this talk, we will discuss how printable organic conjugated semiconducting molecules and polymers are creating new disruptive technologies that are impacting all industries. We will present recent advances in various solid-state device platforms including, organic light-emitting diodes (OLEDs), organic photodetectors (OPDs), organic photovoltaic devices (OPVs), and organic thin-film transistors (OTFTs). We will emphasize the importance of interfaces in devices and show examples on how to engineer their electrical properties. We will present a simple processing technique for the electrical doping of organic semiconductors over a limited depth near the surface of the film that is based on immersing the film into a polyoxometalate solution. Such approached can drastically reduce the fabrication cost of such devices, simplify device architecture, and lead to all-organic devices fabricated by all-additive printing techniques. As an illustration of the simplicity and versatility of this process we will discuss how high-performance organic solar cells with simplified architecture can be implemented. Finally, we will present the results of a detailed operational lifetime study of OTFTs showing that organic photonics and electronics can yield a stability level superior to that of amorphous silicon.

Abstract: 

There are many successful applications of deep learning in solving challenging and difficult problems in recent years. An excellent example is its application in medical image analysis. Dr. Heng’s group is the first to employ 3D convolutional neural networks for automatic detection of cerebral micro-bleeds from MR images. They also proposed multi-level contextual 3D convolutional neural network framework for false positive reduction in automated pulmonary nodule detection. They further proposed a novel and efficient 3D CNN equipped with a 3D deep supervision mechanism to comprehensively address the challenges of optimization difficulties of 3D networks and inadequacy of medical training samples. Their successful deep learning applications cover a wide spectrum of medical image modalities, include histopathological imaging, ultrasound imaging, MR/CT imaging, dermoscopy imaging and colonoscopy videos. Concurrently, there are also many significant and promising developments in virtual reality that are applicable for medical applications. Virtual reality based surgical simulation can provide a cost-effective and efficient way to train novices. In order to achieve the goal of delivering specialized training of a surgical procedure, one practical solution is to construct a realistic virtual environment through intelligent integration of medical imaging, motion tracking, physically based simulation, haptic feedback and visual rendering. In this talk, Dr. Heng shall present their recent works in using deep learning for medical image analysis and introduce some VR-based surgical simulators they have developed.

报告摘要:

表面增强拉曼光谱(SERS)利用Ag、Au等纳米结构,能显著增强吸附在纳米结构表面的分子的拉曼信号,并以超高表面灵敏度获得样品自身的指纹振动信息,是极具前景的表界面和生物分析检测技术。但是,由于生物细胞体系自身的复杂性,以及光-纳米材料表面-生物体系三者间异常复杂的相互作用,使得SERS检测结果的可靠性相对较差,也制约了其在生物医学领域内的广泛应用。本次报告将讨论SERS在生物检测中的可靠性问题,以及存在机遇和挑战。为了拓展拉曼光谱在电化学动态反应过程表征中的应用,我们建立了一种基于电化学表面增强拉曼光谱技术的电化学显微镜,可以在电化学反应过程中,利用拉曼信号强度变化,重构电极表面分子局域的电化学电流,获得局域的电化学信息。


Abstract: 

Surface-nhanced Raman Spectroscopy (SERS) is a promising technique, which utilizes nanostructures such as Ag and Au to enhance the Raman signal of molecules adsorbed on the surface of nanostructures and obtain the fingerprint vibrational information of samples with an ultra-high surface sensitivity. However, due to the complexity of biological systems and the extremely complex interaction between light, nanomaterial surface and biological system, the reliability of SERS is relatively poor, which also restricts its wide application in the field of biomedicine. This report will discuss the reliability of SERS in biological detection, as well as the opportunities and challenges. In order to expand the application of Raman spectroscopy in the characterization of electrochemical dynamic reaction processes, an electrochemical microscope on the basis of electrochemical surface-enhanced Raman spectroscopy (SERS) technology was established. The local electrochemical current of the molecule on the electrode surface could be reconstructed by the change of Raman signal intensity, and the local electrochemical information could be obtained during the process of electrochemical reaction.

报告摘要:

太赫兹辐射具有很多独特的优点,在通讯和成像领域具有重要的应用。相比太赫兹的源和探测器,太赫兹的功能器件都还不成熟,阻碍了太赫兹技术的广泛应用。本报告介绍首都师范大学超材料与器件北京市重点实验室在太赫兹波前获取和调控方面取得的进展。利用自主研发的太赫兹脉冲波焦平面成像系统实现太赫兹辐射的频率、振幅、相位以及偏振态的测量,并利用这套系统实现对涡旋光束和太赫兹波段表面等离子体器件的的表征。利用超构表面技术实现太赫兹波前的调控,设计了超薄太赫兹平板透镜,长焦深透镜,多焦点透镜、太赫兹全息、分色成像全息以及偏振选择透镜等器件。并利用半导体材料在太赫兹波段特殊的光电调控特性,提出了太赫兹波前调制器,实现了基于动态超构表面的太赫兹波前调控。


Abstract: 

Due to many unique advantages of terahertz radiation, it has important potential applications in the field of communication and imaging. Compared with the sources and detectors of terahertz, the functional devices of terahertz are still immature, which hinders the wide application of terahertz technology. This report describes the progress of terahertz wavefront acquisition and modulation in Beijing Key Laboratory of Metamaterials and Devices, Capital Normal University. The frequency, amplitude, phase and polarization of terahertz radiation are measured by a self-developed terahertz pulsed focal plane imaging system. The vortex beam and surface plasmon devices in terahertz band are characterized by this system. The terahertz wavefront can also be modulated by metasurface technology. The ultra-thin terahertz flat lens, long focal depth lens, multi-focal lens, terahertz holography, color-splitting imaging holography and polarization-selective lens are designed. A terahertz wavefront modulator is proposed based on the photoelectric characteristics of semiconductor materials in the terahertz band, and the terahertz wavefront modulation based on the dynamic metasurface is also realized.

报告摘要:

钙钛矿电池由于其优异的光电性能及易于制备的特点,在最近的几年得到了快速发展。在这里,我将主要介绍我们在制备面积超过1 cm2的高效稳定钙钛矿电池方面的工作。我们利用重掺杂高电导率无机电荷传输材料,获得了首个钙钛矿电池认证效率。我们利用渐变异质结结构改善了甲咪基钙钛矿材料在反式结构中电子收集效率。此外,我们结合添加剂工程,在大于1 cm2的面积上获得了19.2%的认证效率。

从小面积电池到大面积模块过渡,最难的环节是开发出制备大面积低缺陷钙钛矿薄膜的方法。此前,我们开发了一种软膜法能够制备这样的薄膜并具有较大的晶粒尺寸。基于此方法,我们成功制备51 cm2的高质量薄膜。最近,我们又开发出一种新的无溶剂钙钛矿前驱体。将此种前驱体应用于软膜法中,我们成功制备了6*6 cm2的钙钛矿模块,获得了12.1%的AIST认证效率,这也是世界首个钙钛矿模块的效率记录。此外,我也会将我们关于钙钛矿电池成本分析和稳定性方面的工作向大家介绍一下。


Abstract: 

Here I will introduce our main achievements in the fabrication of efficient and stable PSCs with working area over one centimetre square. The first recorded efficiency of perovskite solar cells was obtained by using heavily doped inorganic charge extraction layers with high conductivity. New graded heterojunction (GHJ) structure was designed to improve the electron collection and in inverted structure with Formamidinium based perovskites. Combined with additive engineering, an certified efficiency of 19.2% was achieved.

For further enlargement of the cell to large-area module, the big challenge is to develop new deposition methods suitable for fabricating large-area perovskite films with low defects density. A soft-cover deposition method was proposed to achieve this goal. We recently synthesized a new non-solvent perovskite precursor and modified the soft-cover method. This combination led to the first perovskite module efficiency record. Furthermore, I will also talk the cost analysis and stability issue of PSCs.
