2JOURNEY TO RECOVERY显示文摘The lines of masked passengers boarding trains in Wuhan on April 8 had a special significance.They marked the lifting of outbound travel restrictions after Wuhan turned the tide in its battle against the novel coronavirus epidemic following almost 11 weeks of lockdown.The sprawling city of 11 million people witnessed over 50,000 people contract the disease and more than 2,500 deaths,accounting for the lion's share of the toll in China.On January 23,to cope with the public health emergency,public transport was suspended and all outbound flights and trains were stopped to contain the epidemic.Duan Wei(图) Ma Gengping(图) 2020Beijing Review2020,63,16:0
3Controllable coating NiAl-layered double hydroxides on carbon nanofibers as anticorrosive microwave absorbers显示文摘For harsh real-world service settings,it is essential to build corrosion-resistant,diverse,and effective microwave absorbers.Herein,we successfully prepared a 3D NiAl-layered double hydroxide/carbon nanofibers(NiAl-LDH/CNFs)composite material as an anticorrosive microwave absorber assisted by an atomic layer deposition(ALD)method.The size,coating thickness,and content of NiAl-LDH can be readily adjusted by changing the ALD cycling numbers.The optimized NiAl-LDH/CNFs demonstrates prominent microwave absorbing properties including the strongest reflection loss of–55.65 dB and the widest effective absorption bandwidth of 4.80 GHz with only 15 wt%loading.The reasons for performance improvement are the cooperative effect of interfacial polarization loss,conduction loss,and three-dimensional porous structure.Moreover,due to the synergistic effects between the excellent impermeability of CNFs and the trapping ability of NiAl-LDH for chloride ions,NiAl-LDH/CNFs exhibits strong corrosion resistances under acidic,neutral,and alkaline conditions.NiAl-LDH/CNFs should be a potential candidate to simultaneously use for microwave absorption and corrosion resistance,and this work provides a certain guiding significance for designing microwave absorbers that satisfy the corrosion resistance.Ying Zhang Liang Li Changlong Du Gengping Wan Qiyi Wei Xueqing Zhou Yanran Su Yang Xu Guizhen Wang 2023Journal of Materials Science & Technology2023,,20:0
