Major Progress Achieved in Displacement Sensor Technology with a Sub-nanometer Resolution

After one and a half years' hard work, the research group led by Prof. Xiangzhao WANG has successfully developed a micro-displacement measurement sensor with sub-nanometer resolution at Laboratory of Informational Optics in Shanghai Institute of Optics and Fine Mechanics (SIOM), CAS. Even in the case of existing external disturbances, the micro-displacement varied rapidly or slowly can be transformed into corresponding electrical signal by the sensor with a sub-nanometer resolution. The measurement accuracy is less than 2 nm and resolution is less than 1nm. 10 national patents have been granted.

Research on Constructing Ordered Arrays of Calixarenes

Great progress in constructing ordered arrays of calixarenes have been made by the research group of Prof. Chunli BAI and Lijun WAN at the Key Laboratory of Molecular Nanostructure and Nanotechnology, Institute of Chemistry, Chinese Academy of Sciences. Ordered arrays of calixarenes were successfully constructed by electrochemical self-assembly technique, and were used to include fullerene molecules. The C60/calixarene complex is thus found to form highly ordered arrays. The result is important for the construction of functional nanostructures. The results of its series research were published in Chem. Phys. Lett. and Angew. Chem. Int. Ed..
