Temperature Field Monitoring of an Aluminum Electrolyzer for Lining Defect Diagnosis

Aluminum production is one of the most energy-intensive metallurgical processes, where maintaining the electrolytic cell’s thermal balance is critical to ensuring energy efficiency and equipment service life. Damaging the cathode lining is a serious problem, leading to premature...

Precision-Engineered CsPbBr3 Quantum Dots with Encapsulation and Tunable Size Exhibiting Temperature-Responsive Luminescence for Emerging Sensors

In this work, CsPbBr3 perovskite quantum dots (QDs) were synthesised by hot injection, with reaction time controlling nanocrystal size and emission from 493 to 515 nm. Temperature-dependent photoluminescence (23–80 °C) showed decreasing intensity but stable peak position. Embeddi...

DASTNet-X: an explainable dual-attention based spatio-temporal network for arrhythmia classification

Deep learning (DL) models have demonstrated strong performance in electrocardiography (ECG) arrhythmia classification. However, the criteria and processes for selecting ECG samples for analysis are often unclear. This lack of transparency, together with the challenge of interpret...
