2D layered metal hydroxides (LMH) are promising materials for electrochemical energy conversion and storage. Compared with exfoliation of bulk layered materials, wet chemistry synthesis of 2D LMH materials under mild conditions still remains a big challenge. Here, an “MgO‐mediated strategy” for mass production of various 2D LMH nanosheets is presented by hydrolyzing MgO in metal salt aqueous solutions...
Layered lithium transition‐metal oxides, with large capacity and high discharge platform, are promising cathode materials for Li‐ion batteries. However, their high‐rate cycling stability still remains a large challenge. Herein, hierarchical LiNi1/3Co1/3Mn1/3O2 polyhedron assemblies are obtained through in situ chelation of transition metal ions (Ni2+, Co2+, and Mn2+) with amide groups uniformly distributed...
Rational design and controllable synthesis of nanostructured materials with unique microstructure and excellent electrochemical performance for energy storage are crucially desired. In this paper, a facile method is reported for general synthesis of hierarchically core–shell structured Ni3S2@NiMoO4 nanowires (NWs) as a binder‐free electrode for asymmetric supercapacitors. Due to the intimate contact...
Hierarchical metal nanostructures containing 1D nanobuilding blocks have stimulated great interest due to their abundant active sites for catalysis. Herein, hierarchical 4H/face‐centered cubic (fcc) Ru nanotubes (NTs) are synthesized by a hard template‐mediated method, in which 4H/fcc Au nanowires (NWs) serve as sacrificial templates which are then etched by copper ions (Cu2+) in dimethylformamide...
In article number 1801893, Sara Mahshid and co‐workers develop a nanostructured fluidic device for sensitive analysis of pathogenic bacteria based on a hierarchical nano/micro‐islands detection platform enabling direct, rapid, and quantifiable detection of bacteria. Performance of the integrated device in probe‐free optical detection of pathogenic bacteria such as Escherichia coli and optoimmunocapturing...
Efficient capture and rapid detection of pathogenic bacteria from body fluids lead to early diagnostics of bacterial infections and significantly enhance the survival rate. We propose a universal nano/microfluidic device integrated with a 3D nanostructured detection platform for sensitive and quantifiable detection of pathogenic bacteria. Surface characterization of the nanostructured detection platform...
