## Abstract A new apparatus is described whereby the thermal behavior, including the deformation temperature, of a thermoplastic material may be obtained. The apparatus is intended to replace ASTM procedure No. D648β56 and has several advantages over that procedure. Thermal behavior of several comm
## Abstract The paramagnetic Si/Al material doped with 19.8% (weight) of Mn^2+^ has been characterized by the ^1^H, ^13^C, ^27^Al, ^29^Si MAS NMR spectra and the ^1^H, ^29^Si __T__~1~MAS relaxation measurements as a gel dried at 130 Β°C and as samples calcined at 504, 540 and 650 Β°C. It has been dem
