TL;DR: In this paper, the authors investigated heat transfer in one-dimensional multi-layer models of polymer foams and determined their equivalent thermal conductivities, i.e., combined heat transfer by conduction and radiation in both phases and partial photon reflection on phase interfaces, and found that although radiation can account for more than one-third of the total heat flux, it can be reduced in foam with cell-sizes below 100 μ m and be almost nullified by decreasing the foam cell size to sub-micron range.

TL;DR: In this article, a model for the kinetics of multiple overlapping reactions is presented for the modeling of the feed-to-glass conversion in a waste-glass melter, and the model simulates multiple gas-evolving reactions that occur during heating of a high-alumina high-level waste melter feed.

TL;DR: In this paper, the authors used simultaneous differential scanning calorimetry-thermogravimetry (DSC-TGA) to investigate cold-cap reactions in a high-alumina high-level waste melter feed.

TL;DR: In this paper, a model of coupled heat transfer by conduction and radiation through computer-reconstructed domains is proposed, which considers absorbing and emitting gas and solid phases and partial photon reflection on phase interfaces.

TL;DR: In this paper, the phase composition of industrial PE samples with crystallinities from 35 to 82.5 % was studied using low-field 1H NMR and the characteristic dimensions of the lamellar stacks were measured using small-angle X-ray scattering (SAXS).
