Developing an Emperical Equation for the Diameter of DWNT and RBM Frequency of RRS
Abstract: Many experiments of resonant Raman spectroscopy have been carried out to successfully assign the radial breathing mode frequency of the inner and outer tube of double walled carbon nanotube. Experimental values show clear indication that these frequencies depend heavily on inter tube interaction. All the previous efforts to establish a relation between RBM frequency and diameter have not taken the inter-tube distance factor into account. Here, for the first time …

AI-Assisted Kinetic Modeling of PLA Hydrolysis Under Subcritical Water Conditions for Sustainable Polymer Recycling
Abstract: The accumulation of poly (lactic acid) (PLA) in terrestrial and marine ecosystems has intensified the demand for closed-loop, green recycling technologies. Subcritical water (SCW) hydrolysis offers a promising, catalyst-free pathway for the rapid depolymerization of PLA into its constituent monomer, lactic acid. However, the complex, highly non-linear kinetics governing macro-molecular degradation under variable hydrothermal conditions limit real-time process optimization and industrial scalability. This study develops a novel artificial intelligence (AI)-assisted …
