The study focuses on the rapid green synthesis of silver nanoparticles (AgNPs) and alginate-silver nanocomposite (Alg-AgNc) beads using sweet basil or Mashmoom (Ocimum basilicum), a common household medicinal herb in Bahrain. The aqueous extract of mashmoom was used as a reducing and stabilizing agent in the reduction of the precursor salt, silver nitrate, and formation of stable AgNPs. The Alg-AgNc beads were prepared by ionotropic gelation of sodium alginate-AgNPs solution [...]

This paper investigates data-driven strain energy prediction for heterogeneous elastic materials using the Mechanical MNIST benchmark dataset (60,000 28 × 28 stiffness maps by precomputed finite-element results). The results by classical regression models (linear regression, random forest, and gradient boosting) using hand-crafted features were compared with the results by the deep learning models (Convolutional neural network (CNN) and residual network (ResNet)) trained end-to-end on images.
