Removal of Thiophene from Model Fuel Using Titanium Catalyst
Abstract: Organosulfur compounds like thiophene (Th) and its alkyl derivatives are the major unwanted species present in crude oil fractions as they lead to the formation of sulfur oxides after combustion of the fuel and these oxides of sulfur cause severe environmental damage. Oxidative desulfurization (ODS) process is considered as one of the best alternative deep desulfurization technologies compared to hydrodesulfurization. In the ODS process, the sulfur compounds are oxidized to …

Digital Twin Assisted Intelligent Prediction of Polymer Composite Degradation Under Environmental Exposure
Abstract: Polymer matrix composites (PMCs) deployed in aerospace, marine, automotive, and renewable-energy structures are continuously subjected to coupled environmental stressors — ultraviolet (UV) radiation, moisture ingress, thermal cycling, and mechanical loading — that progressively degrade their mechanical performance. Conventional accelerated ageing tests and empirical lifetime models are time-consuming, destructive, and poorly suited to in-service, asset-specific degradation forecasting. This paper proposes a Digital Twin (DT) assisted intelligent prediction framework that fuses a …
