By incorporating MXenes into combination therapies, researchers have demonstrated enhanced therapeutic efficacy through synergistic mechanisms that improve drug delivery, increase localized heating, and amplify the generation of reactive oxygen species, thereby effectively targeting and eliminating cancer cells or contaminations.

In this study, a nanocomposite diode based on lanthanum-doped polyethyleneimine-functionalized graphene quantum dots was fabricated to investigate the impact of temperature on diode performance. The diode's current–voltage characteristics were measured experimentally over a temperature range of 77–400 K. These measurements were used to train machine learning algorithms. Specifically, K-Nearest Neighbors, Decision Trees, and Gradient Boosting were employed to predict current–voltage characteristics at temperatures lacking experimental data. The performance of these models was evaluated using metrics such as the coefficient of determination, mean squared error, and mean absolute error. Among the models, Gradient Boosting demonstrated the highest accuracy, achieving a coefficient of determination of 0.9998, a mean squared error of 0.0026, and a mean absolute error of 0.0222, though accuracy varied with temperature.
