We propose a novel, practical way to prepare nanoporous Sb with different morphologies and particles of varying size through chemical dealloying Al–Sb alloy ribbon precursors compositions, top-down process.
Monolithic nanoporous copper (NPC) ribbons can be fabricated through chemical dealloying of melt-spun Al−Cu alloys with 33−50 at % Cu under free corrosion conditions. The microstructure these NPC was characterized using X-ray diffraction, scanning electron microscopy, energy dispersive analysis, and transmission microscopy. experimental results show that the are composed one or a combination Al2Cu AlCu intermetallic compounds. Both fully dealloyed, synergetic in two-phase formation...
We describe the fabrication of novel PdCu bimetallic nanocomposites with hierarchically hollow structures through a simple galvanic replacement reaction using dealloyed nanoporous copper (NPC) as both template and reducing agent. The process was monitored by UV−vis absorbance spectra X-ray diffraction (XRD), which clearly demonstrate structure evolution from NPC precursor to Pd-rich alloy upon completion reaction. Structure characterization means transmission electron microscope (TEM)...
Advanced arrayed Bi nanorod bundles prepared by chemical dealloying exhibit an excellent electrochemical performance as SIB anode due to their high ion accessibility and fast electron transport.
We present a novel and simple strategy to synthesize nanoporous gold (NPG) ribbons with bimodal channel size distributions. The NPG can be fabricated from Al−Au alloys through rapid solidification chemical dealloying. microstructure of these was characterized using X-ray diffraction, scanning electron microscopy, energy dispersive analysis, transmission high-resolution microscopy. These are composed large-sized channels (hundreds nanometers) highly porous walls (tens nanometers). Both large-...
The wettability of defective graphene and its relation with the interfacial property water have not been well tackled. By conducting molecular dynamics simulations on interactions between some vacancy defects, we show that contact angle is more sensitive to Stone–Wales (SW) single-vacancy (SV) defects than double-vacancy (DV) defects. Density profiles indicate sheet induces change from a liquid into an ordered three-layer structure, which restricts self-diffusion molecules seriously....
This article considers the roles of metalloids in two typical Fe-based glass former alloys (Fe78Si9B13 and Fe80P11C9) liquid state by using ab initio molecular dynamics simulations. It presents that Fe78Si9B13 alloy is mainly composed B-centered prism-like clusters bcc-like Fe-Si solid solution, while P-centered antiprism-like C-centered dominate Fe80P11C9 alloy. The different stabilities can be attributed to local environments around P Si atoms avoidance metalloid atoms. appearance...
We study the dynamic behavior of CuZr-based melts well above liquidus temperature. The results show a discontinuous change in viscosity during cooling, which is attributed to an underlying liquid-liquid phase transition (LLPT) these melts. LLPT further verified by thermodynamic response same temperature region. find that Cu46Zr46Al8 melt reversible 1350 K upon repeated heating and cooling. Based on concept fluid cluster metallic melts, structural from strongly ordered high-density liquids...
The structure of the liquid and amorphous Fe78Si9B13 alloys is investigated by ab initio molecular dynamics simulation. bears a strong resemblance to on both atomic electronic levels. Chemical short-range order evidenced higher Fe coordinating proportion than nominal one around Si B atoms in states. distances local densities states show that Fe–Si bonding stronger Fe–B tend repulse each other.
