Carbon nanotubes, as carbon allotropes distinguished by their intricate structures and exceptional physicochemical properties, have demonstrated substantial progress in recent years across diverse domains, including energy production, chemical synthesis, environmental preservation. They exhibit notable attributes such high thermal stability, superior adsorption capacity, a specific surface area, rendering them superb catalyst supports. Particularly electrochemical storage, CNTs are extensively employed supercapacitor electrodes owing to elevated electrical conductivity, mechanical robustness, electrocatalytic prowess, which facilitate significant storage capabilities. Their pore architecture reactive sites make functionalized nanotubes well suited for synthesizing composite materials with components, ideal sequestering dioxide from both atmospheric indoor environments. This review presents comprehensive examination of nanotube synthesis methodologies, encompassing vapor deposition, arc discharge, laser ablation, evaluates impacts on the structural functional properties nanotubes. Furthermore, this article underscores applications fields fuel cells, photocatalysis, ammonia dry methane reforming, Fischer–Tropsch supercapacitors. Despite considerable potential manufacturing processes remain costly, impeding large-scale industrial production. concludes addressing challenges fabricating composites outlining future development prospects.

Achieving high robust aluminum alloy annular laser directed energy deposition based on thermal field assistance system

Journal of Laser Applications, Год журнала: 2025, Номер 37(1)

Опубликована: Янв. 27, 2025

High thermal conductivity and large fluctuations in laser absorptivity with temperature make aluminum alloy prone to deformations, collapses, spheroidization, other defects during directed energy deposition (DED) processes. To achieve stable high-quality annular DED (AL-DED) of alloy, an situ field assistance system was designed, wherein a preheating-cooling control balance model established. The effect the AL-DED process AlSi10Mg has been evaluated, ability on analyzed. A continuous 500-layer forming conducted. results indicate that can component process, causing absorption rate uniform fields, while reducing surface roughness components 2.3 μm. microstructure elemental distribution were uniform, transforming Al–Si eutectic structure from mesh-like dispersed and, consequently, achieving 500-layer, 2.0 mm-thick Al thin-walled high dimensional accuracy stability. This effectively improves stability field, providing novel ideas for additive manufacturing materials sensitive fields fluctuations, such as copper.
