Nanoporous copper is fabricated by dealloying the amorphous Ti2Cu alloy in 0.03 M HF electrolyte. The pore and ligament sizes of the nanoporous copper can be readily tailored by controlling the dealloying time. The as-prepared nanoporous copper provides fine and uniform nanoflowerpots to grow highly dispersed Au nanoflowers. The blooming Au nanoflowers in the nanoporous copper flowerpots exhibit both high catalytic activity and stability towards the oxidation of glucose, indicating that the amorphous alloys are ideal precursors to form nanoflowerpot which can grow functional nanoflowers.

As a type of nanostructured material with nanosized porosity and ultrahigh specific surface area, nanoporous metals attract much attention in both industrial and theoretical fields. Through molecular dynamics simulations, the strain energy of nanoporous copper is investigated with special consideration on the effect of temperature and strain rate. First, with the variation of temperature and strain rate, the change of both stress and strain energy is plotted. Dislocation movement and structural response of nanoporous copper are explored in different stages of strain. Secondly, yield points und

The current feed capacity of electrical interconnects is mainly limited by the poor electromigration (EM) resistance of lead free-solder interconnects. Thus, the community investigates alternative interconnect approaches and materials, e.g. all-copper interconnects using copper pastes. EM is an electron scattering based transport of metal atoms, occurring at high current densities, resulting in voids and thus finally leads to an open interconnect. For all-copper interconnects, it is expected that the maximum current density could be increased, while power losses can be mitigated, due to the hi

With the implementation of the selected modes of laser treatment on L62 brass samples with a thickness of 50 µm leads to the formation of wrinkled relief, which indicates an increment of alloy volume in this area, that is, a porosity increment in the metallic material. Submicroporous and nanoporous structures are formed in the copper-zinc L62 alloy sample, which appear on the surface of the sample. Nanopores have a shape similar to equiaxial.

Nanoporous copper as a robust and efficient electrocatalyst for the electrocatalytic reduction of CO2 in ionic liquid has been successfully developed due to its advantages of high surface area, open porosity and high catalysis efficiency. Nanoporous copper film was prepared by a simple dealloying method and can be directly fabricated on the surface of the electrode. The electrochemical property for electrocatalytic reduction of CO2 in ionic liquid was investigated by cyclic voltammogram (CV), showing enhanced electrocatalytic activity due to its nanoporous structure.

Currently, there is a shortage of potable water in several regions. Various alternative methods exist for producing purified water; however, one particular technology known as solar desalination is gaining prominence as a sustainable and environmentally friendly solution. Solar desalination harnesses solar energy to produce fresh water in regions with abundant sunlight. This study involved the fabrication of a nanostructured porous material composed of copper using anodization, followed by copper electroplating. In order to create three distinct nanoporous structures, we utilized three anodiza

This study explores the mechanical and optical properties of nanoporous copper (NPC) films dealloyed in acid and base using qualitative and quantitative measurements. Two types of NPC films (NPC 1 and NPC 2) were prepared by dealloying precursor films in different corrosive solutions. The films were characterized using atomic force microscopy (AFM) and scattering scanning near-field optical microscopy (s-SNOM). The AFM analysis revealed distinct nanoporous structures in both films, with NPC 2 showing larger pore sizes and the presence of copper aggregations on the surface. Rugosity measures sh

The efficiency of photocatalytic decomposition of methyl orange solutions on the surface of nanoporous layers of copper, silver and their iodides has been studied. It is shows that nanoporous layers on metal substrates have two absorption bands: they absorb radiation in the UV and Vis spectral range. The process of decomposition of methyl orange molecules on the surface of metal-semiconductor nanostructures Cu-CuI and Ag-AgI occurs under the action of UV and Vis irradiation. While transparency of the methyl orange solution increases.

Preparing copper-based azide by in situ reaction is well-suited for MEMS processing technology and holds promising prospects in the field of MEMS micro-initiators. This study involved the preparation of porous copper with particle sizes of approximately 30 nm, 60 nm and 100 nm through powder sintering. These were used as precursors for a gas–solid in situ azide reaction to produce copper-based azide with varying morphologies and compositions. Copper-based azide micro-initiators were designed, and their output performance was evaluated using CL-20 and HNS-IV explosives. Analytical results revea
