Abstract A graphite thin film was investigated as the drain and source electrodes for bottom‐contact organic field‐effect transistors (BC OFETs). Highly conducting (10 2 S cm −1 ) at room temperature were obtained from pyrolyzed poly(l,3,4‐oxadiazole) (PPOD) films that prepatterned with a low‐cost inkjet printing method. Compared to devices traditional Au electrodes, BC OFETs showed rather high performances when using these source/drain without any further modification. Being based on...
Walking has a positive impact on people’s emotional health. However, in the case of serious air pollution, it is controversial whether walking exercise can still improve individuals’ Using data from 2014 wave China Labor-Force Dynamics Survey, this study explored relationship between and health with different levels environmental pollution. The results indicated that respondents who took regular walks had better than those did not walk regularly. For whose main mode physical was walking,...
