Volcanic gas emission measurements inform predictions of hazard and atmospheric impacts. For these measurements, Multi-Gas sensors provide low-cost in situ monitoring of gas composition but to date have lacked the ability to detect halogens. Here, tw

Characterization of polymers by dielectric spectroscopy (TSC)

Autor: T. Thomas, A. Bernes, J.P. Ibar, J. R. Saffell

Publikováno v: 6th International Symposium on Electrets,(ISE 6) Proceedings..

The TSC (thermally stimulated current) spectrum of amorphous and semicrystalline polymers is presented after a brief review of the principles of TSC. The effects of chemical structure and physical parameters are presented. An automated technique for

The influence of thermal history on internal stress distributions in sheets of PMMA and polycarbonate

Autor: Alan H. Windle, J. R. Saffell

Publikováno v: Journal of Applied Polymer Science. 25:1117-1129

The through-thickness birefringent patterns (nx – nz) of PMMA and polycarbonate (PC) are measured as a function of thickness, cooling rate, and annealing time. A method is demonstrated for separating the elastic stress from the residual birefringen
