The TG and DTG characterization of PMMA and complex materials prepared by ultrasonic excitation showed that the radicals generated by ultrasonic excitation were uniformly distributed and did not generate unsaturated double bonded polymers. The electrical conductivity of the Graphene/PMMA composites prepared by ultrasonic excitation at a graphene content of 1 wt% increased to 1.13 × 10-1 S/cm, which is better than that of the Graphene/PMMA prepared by in situ polymerization. This may be attributed to the ultrasound-assisted supercrit

The current implementation project aimed to improve patients' sleep quality in a hospital by implementing targeted interventions to reduce sleep disturbances. The Silent Night project was implemented in two general units of an academic tertiary hospital. The project comprised three phases preimplementation, implementation, and postimplementation. Patient surveys were administered to obtain patients' perspectives on the sources of noise disturbances at night. Noise-monitoring machines were installed in two wards to obtain objective dat
