| 1 | In situ dynamics response mechanism of the tunable length-diameter ratio nanochains for excellent microwave absorber显示文摘Faster response benefits the high-performance of magnetic material in various live applications.Hence,enhancing response speed toward the applied field via engineering advantages in structures is highly desired.In this paper,the precise synthesis of Co nanochain with the tunable length-diameter ratio is realized via a magnetic-field-guided assembly approach.The Co nanochain exhibits enhanced microwave absorption performance(near to-60 dB,layer thickness 2.2 mm)and broader effective absorption bandwidth(over 2/3 of total S,C,X,Ku bands).Furthermore,the simulated dynamic magnetic response reveals that the domain motion in 1D chain is faster than that in 0D nanoparticle,which is the determining factor of magnetic loss upgrade.Meanwhile,based on the controllable magnetic field experiment via in situ transmission electron microscopy,the association between magnetic response and microstructure is first present at the nanometer-level.The real and imaginary parts of relative complex permeability are determined by the domain migration confined inside Co nanochain and the magnetic flux field surrounded outside Co nanochain,respectively.Importantly,these findings can be extended to the novel design of microwave absorbers and promising candidates of magnetic carriers based on 1D structure. | Wenbin You Ke Pei Liting Yang Xiao Li Xiaofeng Shi Xuefeng Yu Huiqiao Guo Renchao Che | 2020 | Nano Research2020，13，1： | 0 |
| 2 | Seamlessly Merging the Capacity of P into Sb at Same Voltage with Maintained Superior Cycle Stability and Low-temperature Performance for Li-ion Batteries显示文摘Among the alloying-type anodes,elemental Sb possesses the suitable yet safe plateau,simple lithiation pathway,small voltage polarization,high conductivity,and superior cycle stability.However,challenge is that its intrinsic capacity is rather low(660 mAh g^(-1)),<1/6 of silicon.Herein,we propose a seamless integration strategy by merging the voltage and capacity of phosphorus and antimony into a solid solution alloy.Interestingly,the enlistment of P is found greatly enlarge the capacity from 660 to 993 mAh g^(-1) for such Sb_(30)P_(30) solid solution,while maintaining a single and stable discharge plateau(~0.79 V)similar to elemental Sb.Various experimental characterizations including XPS,PDF,Raman,and EDS mapping reveal that in such a material the P and Sb atoms have interacted with each other to form a homogenous solid solution alloy,rather than a simple mixing of the two substances.Thus,the Sb_(30)P_(30) exhibits superior rate performances(807 mAh g^(-1) at 5000 mA g^(-1))and cyclability(821 mAh g^(-1) remained after 300 cycles).Furthermore,such Sb_(60-x)P_(x) alloys can even deliver 621 mAh g^(-1) at30℃,which can be served as the alternative anode materials for high-energy and low-temperature batteries.This unique seamless integration strategy based on solid solution chemistry can be easily leveraged to manipulate the capacity of other electrode materials at similar voltage. | Yaqing Wei Jun He Jie Zhang Mingyang Ou Yanpeng Guo Jiajun Chen Cheng Zeng Jia Xu Jiantao Han Tianyou Zhai Huiqiao Li | 2023 | Energy & Environmental Materials2023，6，2： | 0 |
