Production and Characterization of a Lipopeptide Biosurfactant from Bacillus velezensis SHB.28 Using Date Syrup for Heavy Metal Removal

Biosurfactants are environmentally friendly surface-active compounds with promising applications in environmental remediation. In this study, a biosurfactant-producing bacterium, Bacillus (B.) velezensis SHB.28, was isolated from heavy metal-contaminated soil and evaluated for it...

Advanced numerical modeling of perovskite (CH3NH3PbI3) solar cells using SCAPS-1D optimizing layer architecture for enhanced efficiency

This study compares conventional ITO/ZnO/MAPbI3/NiO/Au and ETL-free ITO/MAPbI3/NiO/Au solar cells using a revised SCAPS-1D model incorporating consistent material parameters, explicit bulk and interface defects, and carrier-selective contacts. The baseline model was benchmarked a...

Combined effects of difenoconazole and salinity stress on growth, photosynthetic pigments, and oxidative responses in tomato (Solanum lycopersicum L.)

Environmental contamination by pesticides and salts is a growing agricultural issue, especially in arid and semi-arid regions. Difenoconazole (DIF), a commonly used fungicide, and sodium chloride (NaCl), a widespread salinity stressor, often coexist in soil and water, yet their c...

Synergic effect of waste brick powder, waste ceramic powder and marble powder on rheological behaviour, mechanical behaviour and carbon footprint of binary and ternary mortars

Although waste brick powder (WBP), waste ceramic powder (WCP), and marble powder (MP) have been individually investigated as cement substitutes, their combined effects on rheological behaviour, mechanical performance, and strength-normalised environmental efficiency remain insuff...

A Neuro-Symbolic Co-Pilot for Autonomous Driving: Post-Hoc Behavioral Discovery for Hierarchical Decision-Making

In the quest for Level 5 autonomous driving, a critical cognitive bottleneck exists between high-frequency mechanical reflexes and low-frequency semantic reasoning. End-to-end Vision-Language-Action (VLA) models provide strong semantic reasoning but introduce inference latency in...
