A novel synthesis of a nanometric MCM-41 from biogenic silica obtained from rice husk is here presented. CTABr and Pluronic F127 surfactants were employed as templating agents to promote the formation of a long-range ordered 2D-hexagonal structure with cylindrical pores and to limit the particle growth at the nanoscale level thus resulting in a material with uniform particle size of 20-30 nm. The physico-chemical properties of this sample (RH-nanoMCM) were investigated through a multi-technique approach, including PXRD, Si MAS NMR, TEM, -potential and N physisorption analysis at 77 K.

Article Synopsis
  • This research focuses on creating sustainable branched polylactide (PLA) materials by using a new hybrid modeling approach that combines first-principles (FP) with artificial neural networks (ANN) for ring-opening polymerization (ROP).
  • The hybrid model was trained effectively, achieving high accuracy with a root mean square error (RMSE) of 0.004 and a regression coefficient of 0.99, allowing it to predict important polymer properties like molecular weights and branching degree.
  • Additionally, the study validated its predictions using various PLA compositions and demonstrated strong connections between the FP model and hybrid ANN through multiobjective optimization.

Current photovoltaic (PV) panels typically contain interconnected solar cells that are vacuum laminated with a polymer encapsulant between two pieces of glass or glass with a polymer backsheet. This packaging approach is ubiquitous in conventional photovoltaic technologies such as silicon and thin-film solar modules, contributing to thermal management, mechanical reinforcement, and environmental protection to enable the long lifetimes necessary to become financially acceptable. Commercial vacuum lamination processes typically occur at 150 °C to ensure cross-linking and/or glass bonding of the encapsulant to the glass and PV cells.
