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 ...

AN ADVANCED, INNOVATIVE THREADED COMPOSITE FASTENER HAS BEEN DEVELOPED BY FIBER CONCEPT, INC. THE NOVEL 3-D FIBER ARCHITECTURE OF THE FASTENER PROVIDES FOR THE CONTINUITY OF THE REINFORCEMENT FIBER THROUGHOUT THE PART SO THAT ANY MACHINING THAT IS PERFORMED ON THE STOCK COMPOSITE DOES NOT INTERFERE WITH THE TRANSFER OF LONGITUDINAL AND TORSIONAL LOAD FROM THE THREADS TO THE BODY OF THE FASTENER. T ...

OUR "SELF-COHERING" METHODS PERMIT INCREASING THE RECEIVE APERTURE OF A LASER RADAR FAR BEYOND WHAT CONVENTIONAL OPTICAL DESIGNS ALLOW, THUS ACHIEVING UNPRECEDENTED RESOLUTION AND RANGE CAPABILITIES. A COHERENT APERTURE IS FORMED FROM A NUMBER OF MUCH SMALLER SUBAPERTURES WITHOUT REQUIRING STRICT MECHANICAL RIGIDITY. THE OTHERWISE USELESS DISTORTED APERTURE IS PHASE CORRECTED WITH NO NEED FOR A "P ...

THE QUANTUM DOT SEMICONDUCTORS, THE SUBJECT OF THIS PROPOSAL, ARE A NEW CLASS OF NONLINEAR OPTICAL MATERIALS WHICH OFFER CONSIDERABLE PROMISE FOR THE FABRICATION OF NOVEL NONLINEAR OPTICAL COMPOSITES AND RESULTING DEVES. THE FILTER GLASSES (A SUBSET OF THIS CLASS OF MATERIALS) ARE NOW WELL KNOWN BUT THE PROSPECTS FOR MOLECULAR ENGINEERING TO MODIFY THE PARTICLES AND/OR THEIR SURFACES TO IMPROVE TH ...

THE USE OF GLOBAL INTERCONNECTS IN DIGITAL OPTICAL COMPUTERSAT THE GATE LEVEL SHOWS THE POTENTIAL TO ACHIEVE GATE INTERCONNECT BANDWIDTH PRODUCTS OF UP TO 10**16 WITH POWER CONSUMPTION ON THE ORDER OF 100W. IN THIS STUDY, METHODS OFHARNESSING THESE INTERCONNECTS FOR WIDEWORD DIGITAL COMPUTATION PRIMITIVES SUCH AS EXCLUSIVE OR, ADD, AND MULTIPLY ARE INVESTIGATED. EFFICIENT IMPLEMENTATION OF THESE P ...
