Based on isothermal holds in a rheometer at various temperatures and times, the PEG materials considered were thermally stable up to 220 °C for 10 min in air or 250 °C for at least 10 min under a nitrogen atmosphere, which is long enough to permit melt extrusion of such materials.
To measure the melting points of such small crystals, researchers float them in a gas and watch as the rigid crystals melt into liquid balls.
In "A Love Story," a shorter version of which appeared in this magazine, the narrator looks at a teen-age lifeguard and thinks, "I love it that he, a child, is guarding me, fiercest of warriors, a mother, strong as stinky cheese, with a ripe, moldy, melted rotten center of such intense complexity and flavor it would kill a boy of his tender age".
I love it that he, a child, really, is guarding me, fiercest of warriors, a mother, strong as stinky cheese, with a ripe, moldy, melted rotten center of such intense complexity and flavor it would kill a boy of his tender age.
Intensified droughts, ocean acidification, global sea level rise, increases in frequency of extreme weather events and glaciers melting are examples of such outcomes that are thought to intensify if appropriate international policies are not endorsed and applied.
What is especially surprising is that other tomb guardians had opposite characteristics; soft, benevolent faces are powerfully attractive and evil might melt in the face of such spirits.
(Here's a figure from a 1994 Science paper pointing to a series of such melt layers, reflecting summer warmth. Please see the postscript below for the key reference, provided by Lora Koenig of NASA).
A fully-Lagrangian numerical model was applied for understanding packed bed structures containing non-spherical solids, such as coke, and the high-temperature melt trickle flow characteristics of such beds.
melting transition, the morphology of such samples changes dramatically on heating to above their nominal melting temperature.
