The chemical structures of TESR-1/4/9 were determined via Fourier transform infrared spectroscopy as well as nuclear magnetic resonance (¹³C-NMR and ¹H-NMR). At room temperature, with 10 wt% of TESR-1, the elongation at break of the epoxy resin (17.67%) was added up to 68.93% in comparison with neat epoxy resin (10.46%). At −70 ℃, with the content of 5 wt% TESR-4, the value of the elongation at break (12.66%) was 37.31% higher than that of the neat epoxy (9.22%). A scanning electron microscope was utilized to observe the fractured surfaces of the resins to investigate the toughening behaviors of the tougheners (TESR-1/4/9). The dynamic mechanical analysis also demonstrated the improvement of the epoxy resins in toughness and good compatibility between TESR-1/4/9 and the epoxy matrix.

Compared with bielemental metal materials, the synergistic action of various elements in high-entropy alloys can effectively improve the lithium/potassium storage efficiency of the materials.

Four elementary algorithms and four ensemble algorithms were employed for model selection. An innovative classification approach was introduced, classifying HEAs into eight distinct structural categories: IMS, AM, FCC + IM, BCC + IM, FCC, SS, BCC, and IM. To enhance feature selection, a three-phase feature screening method was devised, resulting in the identification of seven highly representative features from an initial pool of 64. These selected features were then used for model training. A comparative analysis was conducted against feature sets obtained from six peer-reviewed publications to validate the efficacy of the chosen features. In addition, various oversampling techniques were incorporated to further optimize model performance.

The samples of AA6082/B₄C composite have been subjected to three cycles of multi-axial forging at room temperature, imparting a true strain of 0.3 in each cycle.

The mechanical properties of the composite after MAF have been correlated with dislocation density and evolution of secondary phases using microstructural analysis. Crystallographic texture evolution during MAF of the composite revealed change in the intensity of some texture components which is consistent with the observed variation in the yield strength.

To address these challenges, we have developed an automated synthesis system with AI capability to reproducibly synthesize large quantities of nanostar particles. This platform uses key synthesis parameters such as reagent volume and reagent addition timing to systematically evaluate how these factors determine the optical properties and SERS enhancement of gold nanostars and bimetallic nanostars. We developed and trained different machine learning (ML) models using nanoparticle characterization data to predict absorbance features and SERS enhancement from synthesis parameters. We compared the performance of five different machine learning models, including artificial neural networks, support vector regression, and several tree-based models, including random forest, extreme gradient boost, and categorical boost. A grid matrix was fed into the final trained models to create a look-up table to synthesize gold nanostars with an absorbance maximum at specific wavelengths, culminating in the reproducible synthesis of desired nanostar platforms with a peak absorbance wavelength of less than 1.2% difference compared to the target peak absorbance.
