Ultrathin mesoporous NiO nanosheets on a 3D network of nickel foam have been synthesized by an <italic>in situ</italic> growth strategy in combination with nanoscale design advanced electrochemical performances.
Here, we report the fabrication of ultrafine nanoporous PdFe/Fe3O4 electrocatalysts by a facile dealloying strategy. The results show that phase formation as-dealloyed samples is dependent upon Pd : Fe atomic ratio in Al–Pd–Fe ternary precursors. size ligaments as small ∼2 nm structure samples, which smallest among literature data reported for metals/alloys. present nanocomposites excellent electrocatalytic activities towards oxidation methanol and ethanol alkaline media due to double...
3D binder-free NiO nanorod-anchored Ni foam electrodes synthesized by <italic>in situ</italic> anodization and annealing exhibit superior cyclability high rate performance.
Metal–hydrogen (in particular, Pd–H) interactions have been receiving considerable attention over the past 150 years within scope of hydrogen storage, catalytic hydrogenation, embrittlement and hydrogen-induced interfacial failure. Here, for first time, we show that coupling adsorption absorption could trigger giant reversible strain in bulk nanoporous Pd (np-Pd) a weakly adsorbed NaF electrolyte. The np-Pd with hierarchically porous structure ligament/channel size ∼10 nm was fabricated...
Calcination of anodized nickel foam has been used to synthesize NiO nanopetals electrodes with enhanced electrochemical performance.
Self-healing liquid Ga-based anodes with regulated wetting and working temperatures were fabricated for advanced Mg ion batteries.
Bulk hierarchically nanoporous nickel has been fabricated by dealloying and it shows state-of-the-art electrochemical actuation properties in alkaline electrolytes.
Metallic actuator materials have been comprehensively studied during the last twenty years, but studies limited to noble metals date. Here we report reversible dimensional changes in nanoporous copper made by dealloying an Al-Cu alloy. A strain amplitude of 0.11% is obtained using square wave voltammetry 5 M NaOH, which comparable values reported for a metal such as Pt under electrochemical conditions. The oxide formed on ligaments believed stabilize mechanical properties actuation process....
Metallic actuators have increasingly shown the potential to replace conventional piezoelectric ceramics and conducting polymers. However, it is still a great challenge achieve strain amplitudes over 4% while maintaining fast responses. Herein, we fabricated bulk nanoporous palladium (NP-Pd) with microsheet-array-like hierarchically (MAHNP) structure by dealloying eutectic Al–Pd precursor. The hierarchical consists of array-like microsized channels/sheets disordered nanosized networks....

We present some general concepts and pose questions connected to the difference between ambient temperature passive film formed on elemental aluminum in acid vs that which forms iron-aluminum alloys containing less than about 35–40 at% Al. Data is presented demonstrates non-protective oxide not related impurity effects, either matrix or grain boundaries.We argue ability of form a protective single-phase solid solution alloy atomic-scale size effects vanish once concentration increases 60 at%.

Mild hydrothermal conditions used for the treatment of titanate scrolled nanosheets (SNSs) suspensions (140 °C, 72 h) resulted in a large variety anatase TiO2 anisotropic nano-objects depending on studied parameters: influence medium pH and presence or not structuring agents (SAs). The present work shows that such SNSs, whatever pH, formation single-crystalline nanoneedles (NNs) with specific crystal-elongation direction pH-dependent morphological anisotropy aspect ratios (ARs) from 1 to 8....
In order to circumvent the usual nucleation of randomly distributed tiny metallic dots photodeposited on TiO2 nanoparticles (NPs) induced by conventional UV lamps, we propose synthesize well-controlled nanoheterodimers (NHDs) using lasers focused inside microfluidic reactors strongly photoactivate redox reactions active ions flowing along with in water solution. Since flux photons issued from a laser may be orders magnitude higher than that reachable classical production electron–hole pairs...
