A Transforming Metal Nanocomposite with Large Elastic Strain, Low Modulus, and High Strength
Shijie Hao,Lishan Cui,Daqiang Jiang,Xiaodong Han,Yang Ren,Jiang Jiang,Yong Liu,Zhenyang Liu,Shengcheng Mao,Yandong Wang,Yan Li,Xiaobing Ren,Xiaobing Ren,Xiangdong Ding,Shan Wang,Cun Yu,Xiaobin Shi,Minshu Du,Feng Yang,Yanjun Zheng,Ze Zhang,Ze Zhang,Xiaodong Li,Dennis E. Brown,Ju Li,Ju Li +25 more
TL;DR: By engineering the microstructure and residual stress to couple the true elasticity of Nb nanowires with the pseudoelasticity of a NiTi shape-memory alloy, this work developed an in situ composite that possesses a large quasi-linear elastic strain of over 6%, a low Young's modulus of ~28 gigapascals, and a high yield strength of ~1.65 gigapASCals.

New Insights into the Performance Degradation of Fe-Based Layered Oxides in Sodium-Ion Batteries: Instability of Fe3+/Fe4+ Redox in α-NaFeO2
TL;DR: In this paper, the quasi-reversibility of the layered α-NaFeO2 cathode in sodium-ion cells was examined using a solid-state synthesis method, and the changes in Fe oxidation states and crystallographic structures were examined during the electrochemical sodium cycling of the NaFeO 2 electrodes.

A smart strategy to fabricate Ru nanoparticle inserted porous carbon nanofibers as highly efficient levulinic acid hydrogenation catalysts
Ying Yang,Cheng-Jun Sun,Dennis E. Brown,Liqiang Zhang,Feng Yang,Hairui Zhao,Yue Wang,Xiaohui Ma,Xin Zhang,Yang Ren +9 more
TL;DR: In this paper, Ru-carbon nanofiber (Ru-CNF) catalysts are constructed by cooperative assembly of different proportional RuCl3 and Zn(Ac)2·2H2O along with trimesic acid (H3BTC) in the presence of N,N-dimethylformamide.
