In this study, a high-performance and multi-scale Cu nanoparticle paste is proposed to solve the critical issues of easy oxidation during preparation and storage, as well as high sintering temperature. The multi-scale Cu nanoparticles with sizes ranging from 20 to 140 nm were synthesized simply and efficiently using a liquid-phase reduction method. These nanoparticles were subsequently mixed with a reducing composite solvent to develop a Cu nanoparticle paste. Based on this paste, pressure-assisted Cu–Cu bonding experiments were conducted at various temperatures and durations. The Cu–Cu joints achieve an average shear strength of 33.3 MPa after sintering at 240 °C in a nitrogen atmosphere and even exceed 60 MPa when the temperature is raised to 280 ℃. Additionally, with a reductive surface coating, the multi-scale Cu nanoparticles can be stored for over 20 days under ambient air condition. Besides, the enhanced bonding strength and dense microstructure are attributed to the close-packing effect of multi-scale nanoparticles and the facilitation of small size nanoparticles.

This study employs an artificial neural network (ANN) approach to investigate the electric field dependence of the electrocaloric effect (ECE) in Mn/Y co-doped Ba0.67Sr0.33TiO3 ceramics. By analysing isothermal polarization data, the ANN model accurately predicts key electrocaloric metrics, including entropy change (ΔS), temperature change (ΔT), and heat-carrying capacity (ΔQ), across a range of electric fields. The co-doping of Mn and Y enhances the microstructure, reduces leakage current, and broadens the temperature span of the ceramics, thereby improving the performance of the electrocaloric effect (ECE). The doped ceramics exhibit considerable ECE around room temperature and a relatively broad electrocaloric temperature range. The figures of merit, including the refrigerant capacity and temperature-averaged entropy change, increase with the applied field strength. Furthermore, the study investigates the field dependence of entropy change ΔS and confirms the second-order character of the electric phase transition through master curve analysis. The ANN method is demonstrated to be a rapid and accurate tool for characterising electrocaloric materials, reducing experimental time, and enhancing the optimisation of novel materials.
