Article on Density Functional Theory Simulation: A Review
Abstract: Density Functional Theory (DFT) is a powerful computational approach in quantum mechanics, widely utilized for studying the electronic structure of atoms, molecules, and solids. It treats electron density as the central quantity, bypassing the complexities of solving the Schrödinger equation for individual electrons. The Hohenberg-Kohn theorem establishes that a system's ground-state energy uniquely depends on its electron density, facilitating a focus on this fundamental property. In DFT, the total energy …

A Model to Study the Effect of Homogeneous Nucleation and Emulsifier Amounts on Methyl Methacrylate Emulsion Polymerization in a Seeded Semi-batch Reactor
Abstract: ABSTRACTAn extensive model is developed for methyl methacrylate emulsion polymerization. The assumption of monodispersed particle size distribution is used in developing the model. It is found that inclusion of homogeneous nucleation in the model leads to under prediction of variation of conversion with time. The effects of three different emulsifier amounts on the variation of conversion with time at 50°C isothermal reactor operation, keeping all the other ingredients constant are …
