THERE IS CURRENTLY GREAT DEMAND FOR A MATERIAL WITH SUPERIOR MECHANICAL PROPERTIES THAT CAN BE MAINTAINED TO HIGH TEMPERATURES. SILICON NITRIDE HAS BEEN IDENTIFIED AS ONE OF THE MOST PROMISING CERAMICS TO MEET THESE MATERIAL REQUIREMENTS. TO DATE, RESEARCH ON SI3N4 CERAMICS HAS RESULTED IN SUPERIOR ROOM TEMPERATURE PROPERTIES BUT RETENTION OF THESE PROPERTIES TO HIGH TEMPERATURES HAS NOT BEEN AC ...

THE RECENT AVAILABILITY OF THE CARBON ICOSOHEDRAL MOLECULES, THE FULLERENES, AND THE DISCOVERY OF SUPERCONDUCTIVITY IN ALKALI DOPED FULLERENE DERIVATIVES OPENS NEW AVENUES OF INVESTIGATION INTO SUPERCONDUCTING DEVICES. IN PARTICULAR, THE FULLERIDES ARE PREDICTED TO ACHIEVE HIGH PERFORMANCE AS SUPERCONDUCTING BOLOMETERS. MOST OF THE CURRENT SUPERCONDUCTING INFRARED SENSORS HAVE UTILIZED BOLOMETRI ...

THERE IS A GROWING MARKET IN THE POWDER METALLURGY INDUSTRY FOR INTERMETALLIC POWDER WITH FINE PARTICLE SIZE AND GOOD COMPOSITIONAL CONTROL. A PROCESS TERMED PLASMA INITIATED SELF PROPAGATING HIGH TEMPERATURE SYNTHESIS (PSHS) IS PRESENTLY BEING DEVELOPED TO MEET THE GROWING DEMAND FOR SUCH POWDERS. HOWEVER, FOR SUCH A PROCESS TO COMPETE AGAINST THE EXISTING POWDER MANUFACTURING TECHNIQUES WOULD ...

A significant performance gap exists between the theoretical number of Floating Point Operations (FLOPS) that a HPC machine is capable of sustaining and the number of FLOPS realized by real-world HPC applications. One of the principle reasons for this gap is the parasitic work that computational processes must do to communicate with one another. It has been shown that this communication work can b ...

ADJUSTABLE SPEED THREE-PHASE AC MOTOR DRIVES ARE NOW PREFERRED OVER DC MOTOR SYSTEMS, FOR MANY INDUSTRIAL DRIVES, AND BATTERY-POWERED CARS. THIS IS BECAUSE STATIC INVERTERS, WITH ADJUSTABLE FREQUENCY AND VOLTAGE, ARE RELIABLE AND ECONOMICAL. INDUCTION MOTORS PROVIDE BRUSHLESS OPERATION, BUT THEY HAVE SLIP AND A RELATIVELY LOW LAGGING POWER FACTOR. SYNCHRONOUS MOTORS HAVE BETTER POWER FACTOR AND ...

ALTHOUGH SEVERAL ORGANIC NONLINEAR SINGLE CRYSTALS HAVE BEEN REPORTED TO HAVE EXCEPTIONALLY HIGH FIGURES OF MERIT COMPARED WITH THE BEST INORGANIC CRYSTALS AVAILABLE, ORGANIC NONLINEAR CRYSTALS ARE NOT NOW BEING USED IN INDUSTRIAL, SCIENTIFIC, DEFENSE, AND AEROSPACE LASER SYSTEMS. THIS IS ATTRIBUTED PRINCIPALLY TO THE LACK OF A SUPPLY OF HIGH QUALITY SINGLE CRYSTALS OF A LARGE ENOUGH SIZE TO BE U ...
