冯建东课题组在纳米孔测量方法以及传输现象上取得进展（图）
纳米孔测量方法 纳米孔传输 钙离子成像技术 质子传输成像
2022/1/17
传统的纳米孔测量方法主要是离子电流测量，但此方法无法在纳米尺度上直接实现离子传输路径可视化。与成熟的钙离子成像技术相比，纳米孔质子传输仍然缺乏有效成像手段。发展新的时空分辨技术解析质子传输过程是非常必要的。近日，浙江大学化学系冯建东课题组开发了一种新型质子传输成像方法，提供了一项在光学空间分辨和毫秒时间分辨下可以同时捕获质子传输的路径和动力学过程的研究工具。
中国科学院长春光学精密机械与物理研究所研制的风云三号E星太阳X射线-极紫外成像仪(X-EUV成像仪)是我国首台空间太阳X射线-极紫外波段成像仪器，该仪器于2021年7月5日成功发射，在2021年7月11日~9月1日期间完成初步在轨测试，获得我国第一幅19.5nm太阳极紫外图像和0.6nm~8.0nm的太阳X射线图像。这是我国在该波段太阳成像监测零的突破，将在太阳研究和空间天气预报中发挥重要作用。
近日，常州大学石油化工学院孙小强/王乐勇联合团队青年教师肖唐鑫博士在Chemical Communications上发表研究论文（DOI: 10.1039/D0CC05077F）。光合作用是自然界的普遍现象，是一切生命的基础。模拟光合作用的光能捕获和能量转移过程具有重大意义。本论文利用TPE基团桥连的双UPy化合物作为天线分子和给体，通过四重氢键形成超分子聚合物，并进一步在水溶液中通过微乳化组装成...
融合表观与曲率特征的三维点云眉毛提取
眉毛区域提取 三维眉毛关键点 3D-2D-3D框架 表观特征
2020/5/28
针对三维点云数据中眉毛区域提取研究较少的问题，提出了一种融合表观与曲率特征的方法。首先在3D-2D投影的基础上提出新的3D-2D-3D框架，借助二维关键点实现三维眉毛关键点定位；然后利用眉毛关键点构建感兴趣的区域ROI（regionofinterest），以曲率说明眉毛的形状，并基于表观特征提取三维眉毛区域。在DMCSv1数据库的三维点云数据集上，针对不同表情、不同眉毛形状的眉毛进行提取，实验结果...
