Instrumental development towards single-molecule electronics, sepctroscopics, and electrochemistry

单分子尺度电子学仪器和测试方法

There is a Chinese proverb said: sharp tools make good work. We are developing cutting-edge instruments and technique for single-molecule scale charge transport, spectroscopic, electrochemical  and catalytic studies.

工欲善其事,必先利其器。我们长期工作在应用于单分子电子学、光谱学、电化学和催化的精密科学仪器研发,我们现有的仪器已经达到了皮米-飞安水平控制精度的全自动化控制。

Data mining for single-molecule scale studies

大数据统计分析方法 在单分子尺度实验中的应用

The reproduciblity and reliablity is one of the major challenges for current stage of single-molecule electronics studies. We believe that No statistics, No reliable molecular electronics: the single-molecule electronics measurment only make sense if the results are examined after careful statistics and data mining. We are developing the data mining programs and methodologies for exploring more reliable information from single-molecule scale studies.

实验数据的解读,特别是实验结果的可信度和可重现性是现阶段分子电子学的最大挑战。我们认为统计分析在这一过程中不可或缺。我们将长期进行单分子电子学测试分析软件的研发,并探索新的统计分析算法在单分子尺度研究数据解读中的应用。

Design and fabrication materials using bottom-up approaches and 3D printing technique

三维打印分子材料

We are trying to develop a novel technique exploring the potential of 3D printing technique in the bottom-up fabrication of molecular materials via layer-by layer click-chemistry and self-assembly of organic molecules.

我们也将尝试3D打印技术在Bottom-Up分子材料制备中的应用,通过精确的位移控制,和层层自组装或单分子尺度反应的方式,制备结构高度可控的分子薄膜材料。
