Development of Conceptual Designs for an Improved M41 Type Space Heater
1984Abstract : This report describes an effort to develop conceptual designs for a new improved M41 type space heater. The design features of the current M41 were evaluated and ranked in order of importance. A literature search was performed to base possible design improvements using technology which was not available when the M41 was initally developed ...

Abstract For the characterisation of M41S materials, often only powder X-ray and nitrogen adsorption studies are used. However, the use of transmission electron microscopy in combination with these techniques yields valuable information that is indispensable in order to understand the structure of mesoporous materials.
