	1	Electromagnetic wave absorption performance of Ti_(2)O_(3)and vacancy enhancement effective bandwidth显示文摘The microwave absorption properties of Ti_(2)O_(3)were systematically investigated.Experimental results indicate that Ti_(2)O_(3)has microwave absorption performance with a minimum reflection loss value of-37.6 d B at 18.6 GHz and an effective absorption bandwidth(RL<-10 d B)of 2 GHz.Further,vacancy defects were introduced into Ti_(2)O_(3)by carbothermal reduction.Interestingly,the effective absorption bandwidth of Ti_(2)O_(3)with vacancy defects reach 3.2 GHz.First-principles calculations provide evidence that vacancy defects result in the changes of electric dipole state,leading to a wider effective absorption bandwidth.These results have significance in understanding the origin of electromagnetic phenomena and developing electromagnetic wave absorption materials.

	2	Light-switchable catalytic activity of Cu for oxygen reduction reaction显示文摘The surface reactivity of metals is fundamentally dependent on the local electronic structure generally tailored by atomic compositions and configurations during the synthesis.Herein,we demonstrate that Cu,which is inert for oxygen reduction reaction(ORR)due to the fully occupied d-orbital,could be activated by applying a visible-light irradiation at ambient temperature.The ORR current is increased to 3.3 times higher in the potential range between-0.1 and 0.4 V under the light of 400 mW·cm^-2,and the activity enhancement is proportional to the light intensity.Together with the help of the first-principle calculation,the remarkably enhanced electrocatalytic activity is expected to stem mainly from the decreased metal-adsorbate binding by photoexcita-tion.This finding provides an additional degree of freedom for controlling and manipulating the surface reactivity of metal catalysts besides materials strategy.
