    Valorization of non-living microbial biomass for the adsorptive removal of cationic dyes from multicomponent aqueous systems : mechanistic study, DFT adsorption energy analysis, modeling, and machine learning-based optimization
    (2026) Othmani, Amira; Selatnia, Ammar, Directeur de thèse
    This research investigates the valorization of Streptomyces rimosus biomass, an industrial byproduct of antibiotic production, as an eco-friendly biosorbent for the removal of cationic dyes (Basic Blue 41, Basic Red 46, and Basic Yellow 28) from multicomponent aqueous systems. Comprehensive physicochemical characterization confirmed the presence of active functional groups responsible for high adsorption affinity. Adsorption kinetics and isotherms revealed a spontaneous, endothermic, and predominantly chemisorptive process. Density Functional Theory (DFT) analyses correlated adsorption energies and electronic descriptors with experimental performance, elucidating molecular-level interaction mechanisms. Advanced machine learning models, including a Tri-Hybrid DNN–NAS–PSO framework, provided accurate prediction and optimization of adsorption behavior. The study establishes S. Rimosus biomass as a sustainable and efficient biosorbent, offering a circular-economy approach for industrial wastewater remediation.

    Issue 2 of Volume 5 brings together a diverse collection of original research papers that reflect the breadth and evolving impact of contemporary engineering science. The issue opens with a reflective contribution highlighting a new chapter in the legacy of engineering science, setting the tone for the multidisciplinary works that follow. Several papers address modeling, analysis, and control of complex systems, including stochastic reliability assessment of tall structures, fractional-order control of robotic manipulators, and advanced control strategies for power quality improvement. Environmental and energy-related challenges are also explored through studies on urban runoff under changing climatic conditions and woody biomass cogeneration applied to industrial processes. In parallel, the issue features cutting-edge contributions in signal processing, artificial intelligence, and diagnostics, such as food freshness evaluation using CLIP-based architectures, independent vector analysis methods, and intelligent fault diagnosis of transformer oil. Altogether, this issue presents both theoretical advances and practical applications, underscoring the role of engineering research in addressing modern technological and societal challenges.
