CERAMIC MATERIALS ARE UNDER CONSIDERATION FOR STRUCTURAL COMPONENTS IN ADVANCED HEAT ENGINES FOR SEVERAL REASONS. THE PRIMARY MOTIVATION IS THEIR HIGH STRENGTH UNDER SIGNIFICANTLY INCREASING OPERATING TEMPERATURES. THE USE OF THESE HIGH TEMPERATURE MATERIALS WILL PERMIT BETTER FUEL EFFICIENCY AND REDUCE COOLING SYSTEM REQUIREMENTS. DUE TO THEIR ATOMIC STRUCTURE, CERAMICS INTRINSICALLY EXHIBIT LOW ...

The use of metallized glass fibers as dipoles to reflect and confuse threat radars is a long proven military technology. The simplicity of chaff and the expected long term use of weapon systems which can be defeated by chaff guarantee its utility for many years to come. Advanced Technology Materials (ATM), Inc. has already developed a process for fiber metallization which is suitable for Productio ...

NUCLEATION REMAINS AN OBSTABLE TO THE GROWTH OF SINGLE CRYSTAL FILMS OF DIAMOND ON NON-DIAMOND SUBSTRATES. TWO KEY FACTORS CONTROL THE NUCLEATION OF DIAMOND ON SI: THE FORMATION OF A SIC LAYER BETWEEN THE SI AND THE FILM, AND SPONTANEOUS NUCLEATION OF THE SIC ON THE CONTAMINATED SI SURFACE. IMPRECISE CONTROL OF THE NUCLEATED SIC LAYER HAS DEFEATED PREVIOUS ATTEMPTS AT HETEROEPITAXY OF DIAMOND ON S ...
