Abstract MXene-based (nano)materials have recently emerged as promising solutions for antibiotic photodegradation from aquatic environments, yet they are limited by scalability, stability, and selectivity challenges in practical settings. We formulated Fe 2 O 3 -SiO /MXene ternary nano-photocomposites via coupled wet impregnation sonochemistry approach optimised tetracycline (TC) removal (the second most used worldwide) water using response surface methodology-central composite design (RSM-CCD). The photocatalysts containing various loading of /SiO (5–45 wt%) on the MXene with a range calcination temperatures (300–600 °C) RSM optimisation were synthesised, characterised regarding crystallinity properties, morphology, binding energy, light absorption capability, analysed TC degradation efficiency. 25FeS/MX-450 among all samples demonstrated superior efficiency photocatalytic (98%) under conditions (TC degradation: 39.75 mg/L, time: 68.28 min, pH: 5.57, catalyst dosage: 0.75 g/L). developed area, reduced band gap due to FeS nanoparticles incorporation improved within visible spectrum, played crucial role heterostructure matrix, enhancing photogenerated carriers’ separation transportation capabilities. photoreduction mechanism involved electron transfer MXene, engaging produce •O −, attributed high mobility MXene. Our findings such materials can underscore considerable potential nanomaterials pharmaceutical waterways.

Polymer nanocomposites have received significant scientific and industrial attention due to the synergetic combination of features a polymeric matrix organic or inorganic nanofillers. While experiments been essential for identifying characterizing new materials, their high costs limited trials shifted focus towards applying machine learning (ML) predict nanocomposite properties. This study aims establish connection with tribological performance multi-walled carbon nanotubes (MWCNT) reinforced polymethyl methacrylate (PMMA) through comparison ML techniques. The wear friction characteristics MWCNT-reinforced PMMA were predicted based on three input variables: material weight percentage, load weight, track diameter. using different ensemble algorithms: random forest (RF), extra tree (ET), gradient boosting (GBM). dataset was utilized train proposed models in Python, followed by hyperparameter tuning determine best model predicting target values. results demonstrated that GBM outperformed RF ET models, an R-squared 0.99, RMSE 0.62, MAE 0.18. models' predictions values more precise than These findings indicate techniques, particularly model, can effectively properties nanocomposites, potentially reducing need extensive experimental contributing advancements science.
