Two-Pass Friction Stir Welding of AZ31/AA1050 Bimetallic Butt–Lap Joint

Abstract This study evaluated the feasibility of friction stir welding (FSW) of AZ31/AA1050 bimetallic plates produced by explosive welding. The investigated material had a total thickness of 10 mm (5 + 5 mm) and, after milling, 8 mm (4 + 4 mm). Butt–Lap joints were produced usin...

DualGLEAN: Dual Allocation for VLM-Guided Generalized Category Discovery in Remote Sensing Images

Generalized category discovery (GCD) aims to classify known categories while discovering novel ones in unlabeled data, yet existing methods lack mechanisms to correct boundary-ambiguous samples that receive noisy pseudo-labels, as they primarily rely on visual feature learning wi...

Effect of adding titanium on corrosion and wear resistance of Al0.7CoCrFeNiTix high entropy alloy

Abstract High-entropy alloys based on the Al-Co-Cr-Fe-Ni system are considered promising materials for applications exposed to wear and corrosive environments. In this study, the effect of titanium addition on the microstructure, mechanical properties, tribological performance an...

Quaternary ammonium compounds: outdated or relevant antiviral agents? A narrative review of QAC efficacy against enveloped and non-enveloped viruses

Quaternary ammonium compounds (QACs) are widely used disinfectants, favored for their broad antimicrobial action and safety profile. However, viral disinfection is complex and affected by multiple variables, including the virus’s envelope status, exposure time, temperature, and o...
