The concept of using nanostructured composite materials to enhance the dimensionless thermoelectric figure of merit ZT relative to that for their counterpart homogeneous alloyed bulk crystalline materials of similar chemical…
…°C. Such high temperatures place severe limits on heat transfer fluids; that is, such fluids would need to remain chemically stable, and be compatible with containment materials, at such extreme…
…the phonon velocities for non-propagating modes, since there is no periodicity. Here, we tested the validity of the PGM for amorphous materials by assuming the PGM is applicable, and then,…
We review the status of research on thermal/phonon transport in disordered materials. The term disordered materials is used here to encompass both structural and compositional disorder. It includes structural deviations…
whereby this effect could be exploited to achieve many new results that were previously inconceivable, ranging from higher temperature superconductivity, to synthetic diamonds formed at much lower temperatures. https://news.mit.edu/2021/phonon-catalysis-could-lead-new-field-0528#:~:text=By%20selectively%20heating%20specific%20phonons,that%20could%20have%20broad%20applications https://www.cell.com/cell-reports-physical-science/fulltext/S2666-3864(21)00126-0…
A new reactor concept for two-step partial redox cycles is presented and evaluated by transient simulation that considers heat and mass transfer along with reaction kinetics. The major difference between…
their thermal conductivity from first principles using expressions based on the phonon gas model (PGM). However, modeling of amorphous materials still has many open questions, because the PGM itself becomes…
