Adroit Systems, Inc. will develop a Pulse Detonation Synthesis (PDS) process to manufacture ceramic powders from gas-powder reactant mixtures more efficiently and inexpensively than current methods. A high combustion rate and simple design make the PDS system capable of mass producing these powders, which are used as raw materials for high-temperature, high-performance ceramics and ceramic composi ...

This Phase I project has two primary objectives. The first objective is to evaluate the feasibility of a fully ion implanted fabrication process based on the heterodimensional 2-D MESFET. The new device, the 2-D JFET, will have p+ ion implanted sidegates which laterally modulate a thin, highly doped n-type conducting channel. The 2-D JFET should have excellent high speed, low power characteristics ...

THIS PROPOSAL IS PREPARED IN DIRECT RESPONSE TO THE NRC'S SOLICITATION FOR AN IMPROVED DEVICE TO MEASURE AIR MOVEMENT FOR PERSONNEL RADIATION PROTECTION AND HEALTH PHYSICS APPLICATIONS IN NUCLEAR FACILITIES. THE PURPOSE OF THE NEW DEVICE IS TO PROPERLY LOCATE AIR SAMPLERS SO THAT THE AIR SAMPLED IS REPRESENTATIVE OF THE AIR INHALED BY WORKERS. ALTHOUGH AIR FLOW RATE SENSORS SUCH AS ANEMOMETERS ARE ...

Currently, thermal spray (flame and plasma spray) is the only single step method of applying most metal and non-oxide ceramic coatings to large objects. These coatings are usually of a low quality, and thin films cannot be applied. An in situ deposition technique that inexpensively and easily applies nitrides, carbides and other non-oxide thin or thick films in an environmentally friendly manner i ...

Nicalon fiber-reinforced SiC matrix composites owe their good mechanical properties at room temperature to either C or BN interfaces, which provide a weak interfacial bond. However, C and BN interfaces encounter oxidation problems at elevated temperatures in oxidizing environments resulting in degradation of mechanical properties. Recent efforts to replace C and BN interfaces have identified alu ...

Currently vacuum based methods of PVD and CVD are the only processes for forming GaN thin films and coatings. These methods are usually expensive and are not applied in a production friendly manner. An atmospheric deposition technique that inexpensively and easily applies GaN thin or thick films in an environmentally friendly manner is a priority for any number of DOD and commercial applications. ...

Multi-component dielectric thin films suitable for solid state electronics have been deposited using various conventional chemical vapor deposition (CVD) techniques, including organometallic CVD, plasma enhanced CVD, and low pressure CVD. However, these approaches are difficult to integrate with standard silicon IC processing of ferroelectric DRAM and NVFRAM attributed to high deposition temperat ...
