Developing single-site catalysts featuring maximum atom utilization efficiency is urgently desired to improve oxidation-reduction and cycling capability of lithium-oxygen batteries. Here, we report a green method synthesize isolated cobalt atoms embedded ultrathin nitrogen-rich carbon as dual-catalyst for The achieved electrode with maximized exposed atomic active sites beneficial tailoring formation/decomposition mechanisms uniformly distributed nano-sized lithium peroxide during oxygen...
Metal-organic frameworks (MOFs) manifest enormous potential in promoting electromagnetic wave (EMW) absorption thanks to the tailored components, topological structure, and high porosity. Herein, rodlike conductive MOFs (cMOFs) composed of adjustable metal ions Zn, Cu, Co, or Ni ligands hexahydroxytriphenylene (HHTP) are prepared attain tunable dielectric properties for a EMW absorption. Specifically, influences cMOFs' composition, charge transport characteristic, crystalline anisotropy...
Abstract In pursuit of lightweighting automobiles and low emission transportation, the efforts to develop high-strength, heat-resistant fatigue-resistant Al alloys and/or composites have been ongoing. Here we report a novel matrix composite with ultrahigh strength reinforced by three dimensional network nano-AlN particles for first time. The in-situ synthesized AlN are connected twinning bonding chains built up strengthening enormously like skeleton human body. containing 16.4wt.% shows...
Abstract Ameliorating round‐trip efficiency and mitigating parasitic reaction play a key role in enhancing the activity durability of lithium–oxygen batteries. Herein, it is first reported that Ti 3 C 2 MXene quantum dot clusters full rich crystal defects anchored on N‐doped carbon nanosheets (Ti QDC/N‐C) can operate well as bifunctional catalyst for Li–O The well‐defined grain boundary edge make crucial contributions modulating local unsaturated coordination state active titanium atoms thus...
High-strength lightweight Al-based composites are promising materials for a wide range of applications. To provide high performance, strong bonding interface effective load transfer from the matrix to reinforcement is essential. In this work, novel Al3BC reinforced Al have been in situ fabricated through liquid-solid reaction method and between has unveiled. The HRTEM characterizations on Al3BC/Al verify it be semicoherent structure with definite orientation relationships:...
Pavement piezoelectric energy harvesting technique is to use a Piezoelectric Energy Harvester (PEH) convert the mechanical of vehicles into electrical energy. A lot research has been done on technology collection, but it mainly focused theoretical model and laboratory tests lacks on-site performance evaluation. In this paper, stacked array type PEH designed with protection package, which can improve service life PEH. The demonstration project also carried out test field performance. It found...
Alloy-type anodes in alkaline ion batteries have to face the challenges of huge volume change and giant structure strain/stress upon cycling. Here, reducing stress for advanced performances by voltage regulation is demonstrated using microsized Sn (μ-Sn) sodium as a model. Density functional theory finite element analysis indicate that Sn/NaSn3 crucial phase transition highly responsible inducing surface cracks, particle aggregations, cell failures. Eliminating this control cutoff voltages...
Abstract The Li+ adsorption from aqueous solution by lithium-ion sieve has become one of the most promising methods due to high efficiency and selectivity towards lithium ion (Li+). However, industrial application manganese oxide ion-sieve is limited its difficult separation decrease capacity resulting dissolution loss. In this paper, magnetically recyclable Fe-doped ion-sieves with spinel-structure were proposed prepared LiMn2-xFexO4 synthesized solid state reaction method. effects...
Controlling the anomalous valley Hall (AVH) effect by external means is crucial for valleytronic devices in practical applications; however, most of previously proposed control approaches are either irreversible or volatile. Here, we present a general scheme achieving nonvolatile electrical AVH based on multiferroic van der Waals heterostructure. Using density functional theory calculations and $\mathbit{k}\ifmmode\cdot\else\textperiodcentered\fi{}\mathbit{p}$ model analysis, further...
