CO diffusion and desorption kinetics in CO$_2$ ices

open access: yes, 2017
Diffusion of species in icy dust grain mantles is a fundamental process that shapes the chemistry of interstellar regions; yet measurements of diffusion in interstellar ice analogs are scarce.

The crystallization and crystalline properties of LARC-TPI [PDF]

open access: yes
LARC-TPI, a thermoplastic polyimide, has been studied in order to develop an understanding of its crystalline phase transition. Our experiments suggest that samples synthesized in different laboratories apparently had different degrees of imidization and

Isothermal crystallization kinetics of poly(ethylene terephthalate) and poly(methyl methacrylate) blends

open access: yeseXPRESS Polymer Letters, 2007
Different kinetic models like the Avrami, Tobin and Urbanovici-Segal models have been applied for determining the isothermal crystallization kinetics of virgin poly(ethylene terephthalate) (PET) and PET/poly(methyl methacrylate) (PMMA) blends.

The crystallization of tough thermoplastic resins in the presence of carbon fibers [PDF]

open access: yes
The crystallization kinetics of the thermoplastic resins poly(phenylene sulfide) (PPS) and poly(aryl-ether-ether-ketone) (PEEK) in the presence and in the abscence of carbon fibers was studied.

Synthesis and characterization of Sb/P substituted Ge–Ga–Se–Te bulk glasses

open access: yesScientific Reports
Mixed Se–Te glasses are unique materials for infrared optical applications due to their exceptional IR transparency, molding and fiber-drawing capability, environmental stability, and tailored physical properties.
