Synthesis of Water-soluble Fluorescent Carbon Dots from a One-step Hydrothermal Method with Potato Ying-xiang Sun1,a, Zhi-wei He1,b, Xiang-bao Sun1,c and Zeng-dian Zhao1,d* 1College of Chemical Engineering, Shandong University of Technology, Shandong, Zibo, 255049, China asunyx87@163.com, bzwh12666@126.com, cyangflyfan@126.com , dzdz1266@126.com Keywords: Fluorescent carbon dots, Hydrothermal method, Potato Abstract.
Experimental Materials.
Temperature is a key factor affecting the formation of CDs in the hydrothermal reaction.
The fluorescence CDs particles are obtained by the raw material is not completely carbonized after a certain degree of cross-linking within the environment of high temperature and pressure in the reactor.

A Graphical Approach for Human Skin Moisture Evaluation by Electrical Impedance Spectroscopy Yuxing He1,a, Yonggui Dong2,b 1,2State Key Laboratory of Precision Measurement Technology and Instruments, Department of Precision Instruments and Mechanology, Tsinghua University, Beijing 100084, People’s Republic of China aheyuxing01@126.com, bdongyg@mail.tsinghua.edu.cn Keywords: skin moisture evaluation; graphical approach; electrical impedance spectroscopy; Abstract: A pair of concentrically placed gold electrodes is utilized in contact with human skin surface for moisture evaluation.
As this probe will be used in a dry-contact way with the skin, the measuring surface(the inner circle and the outer ring) is covered with gold material to protect the surface and reduce electrode polarization effect.

Synthesis and biological activities of chalcones derived from nitroacetophenone Xiaoyang Qiu 1, a, Suzhi Li 1 and An-Ran SHI 2 1Department of Chemistry, Shangqiu Normal College, Shangqiu 476000, China 2College of Chemistry and Chemical Engineering, Nanjing University of Science and Technology, Nanjing 210016, China aE-mail: qiuxiaoyang12@163.com Keywords: chalcone, cytotoxic activity, antimicrobial activity, structure-activity relationship Abstract.
Nitrochalcones were studied more as light-sensitive materials, however, their biological activities were not considered as important properties.
The cells were allowed to proliferate in presence of tested material for 48 h, and the results were reported in terms of IC50 values (Table 1).
