In today's era of pursuing efficient energy conversion and storage, materials science plays a crucial role. Among these, foam nickel—a unique three-dimensional porous metallic material—is gradually transitioning from the laboratory to the broad stage of industrial applications. Foam nickel transforms metallic nickel into a sponge-like three-dimensional network structure, internally filled with numerous interconnected micropores. This distinctive architecture endows it with a series of exceptional physicochemical properties: high permeability, excellent air permeability, good corrosion resistance, low density, ultra-large specific surface area, and outstanding electrical and thermal conductivity. These properties enable foam nickel to transcend the limitations of traditional dense metallic materials, serving as a vital bridge between materials science and energy engineering.

The primary application scenarios for sound barriers are concentrated in areas requiring effective control of traffic noise impacts on surrounding environments, with particularly widespread use in urbanization and infrastructure development.

Contemporary designs for expensive theaters and art galleries reflect architects who struggle with the challenge of creating a good sensory experience by finding methods to build spaces that require strict acoustic performance standards without using heavy acoustic materials which would disrupt the artistic integrity of the space. Standard acoustic solutions come with the tendency to hide their functional nature, but open-cell aluminum foam creates an opportunity for architects to use functional materials as part of the spatial storytelling process. The sound-absorbing material functions as an architectural skin that provides light and shadow effects in space.

The oxidation process of foam copper in air is temperature-sensitive, with its oxidation behavior primarily divided into two key stages: ‌Oxidation Initiation and Product Transformation‌: At temperatures between 180-220°C, red cupric oxide (Cu₂O) begins forming on the foam copper surface. Beyond 220°C, the oxidation product transforms into black copper oxide (CuO). For instance, after 2 hours of constant heating at 200°C, cupric oxide coverage reaches approximately 75%. The regulatory effect of temperature on the oxidation reaction manifests as follows: increased temperature accelerates the electronic transition of copper atoms, promoting their bonding with oxygen. Around 200°C, the dissociation energy of oxygen molecules aligns with the requirements for Cu₂O formation. Furthermore, the porous structure of foam copper facilitates oxidation more readily than copper foil.

Foam aluminium is produced by incorporating additives into pure aluminium or aluminium alloys through a foaming process, thereby combining metallic properties with a cellular structure. It exhibits low density, high impact absorption capacity, heat resistance, strong fireproofing, corrosion resistance, sound insulation, low thermal conductivity, high electromagnetic shielding, excellent weather resistance, filtration capabilities, ease of machining, straightforward installation, high forming precision, and suitability for surface coating.

With accelerated urbanization and increased road traffic volume, traffic noise has become one of the major sources of environmental pollution affecting the health and quality of life of residents along roads. Governments and local agencies worldwide face increasing regulatory pressure, requiring the implementation of efficient noise mitigation measures in both new and existing traffic corridors to meet stringent daytime and nighttime noise limits. 

Nickel foam is a highly permeable, low-density, three-dimensional network of foamed metal, and a rapidly developing new material in materials science. The foam structure gives nickel metal an open-cell structure, resulting in excellent permeability and significant heat transfer and dissipation properties.

Foam aluminum: With a density just one-tenth that of water yet capable of floating, it boasts strength five times greater than steel while excelling in both sound insulation and fire resistance. From nuclear fuel transport to starlit ceiling designs, from military aerospace to home renovations, this futuristic material is quietly transforming our lives.
