Thermodynamic collapse in a lattice-gas model for a two-component system of penetrable particles

Derek Frydel、Yan Levin2020-08-17arXiv (Cornell University)

We study a lattice-gas model of penetrable particles on a square-lattice substrate with same-site and nearest-neighbor interactions. Penetrability implies that the number of particles occupying a single lattice site is unlimited and the model itself is intended as a simple representation of penetrable particles encoun…

Techno-Economic Analysis of Microwave-Assisted Conversion Processes

Chirag Mevawala、Debangsu Bhattacharyya2020-08-17OpenAlex

Microwave (MW) is an electromagnetic radiation with a frequency range between 300 MHz to 300 GHz. When a material is irradiated with MWs, it reflects, transmits, and/or absorbs the MW energy. Materials that allow MW to pass through them with negligible interactions or attenuation are called insulating materials. Lastl…
