However, it is challenging to fabricate supercapacitors that can withstand large tensile strain while maintaining high performance. Herein, we report an ultra-stretchable wire-shaped supercapacitor based on carbon nanotube@graphene@MnO2 fibers wound around a superelastic core fiber. The supercapacitor can sustain tensile strain up to 850%, which is the highest value reported for this type of device to date, while maintaining stable electrochemical performance. The energy density of the supercapacitor is 3.37 mWh·cm^-3 at a power density of 54.0 mW·cm^-3. The results show that 82% of the specific capacitance is retained after 1,000 stretch-release cycles with strains of 700%, demonstrating the superior durability of the elastic supercapacitor and showcasing its potential application in ultra-stretchable flexible electronics.展开更多

Of these trials, 2 compared a(modified) prescription of TCM with oseltamivir and 5 compared a patent traditional Chinese drug with oseltamivir. Based on the Meta-analysis,compared to oseltamivir, the(modified) prescription had similar effect in defervescence [WMD=5.66, 95% CI(﹣32.02, 43.35), P=0.77] and viral shedding [WMD=﹣ 6.21, 95% CI(﹣84.19, 71.76), P=0.88], and the patent traditional Chinese drug also had similar effect in viral shedding [WMD=﹣ 0.24,95% CI(﹣4.79, 4.31), P=0.92] but more effective in defervescence [WMD=﹣4.65, 95%CI(﹣8.91, ﹣0.38),P=0.03].CONCLUSION: TCM has potential positive effects in the treatment of influenza.展开更多
