Article Synopsis
- The study uses thermodynamic and kinetic simulations to explore the mechanical properties and behaviors of the Ni-Ti-Cu alloy system, particularly during processes like mechanical alloying and spark plasma sintering.
- The research includes calculations for stable and unstable phases of NiTiCu materials, demonstrating a link between these phases and microstructure changes during production.
- Thermal properties, such as conductivity and specific heat, were measured using laser flash and differential scanning calorimetry methods, showing temperatures that align with theoretical predictions, and the findings offer insights for preparing and applying NiTiCu shape memory alloys.
This paper describes the preparation of new PEG-silica-MWCNTs composites as shape-stabilized phase change materials (ssPCMs) for application in latent heat storage. An innovative method was employed to obtain the new organic-inorganic hybrid materials, in which both a part of the PEG chains, used as the phase change material, and a part of the hydroxyl functionalized multiwall carbon nanotubes (MWCNTs-OH), used as thermo-conductive fillers, were covalently connected by newly formed urethane bonds to the in-situ-generated silica matrix. The study's main aim was to investigate the optimal amount of PEG that can be added to the fixed sol-gel reaction mixture so that no leakage of PEG occurs after repeated heating-cooling cycles.
