SBIR Topic SB163-004 describes DARPAs need to develop a real-time system for active feedback control and process characterization of multi-material additive manufacturing. To fill this need, Bridger Photonics, Inc. (Bridger) will prove out an ...

This Phase I SBIR effort will examine the feasibility of fabricating quantum frequency conversion (QFC) devices with cutting edge performance to satisfy DARPA quantum information science applications. Quasi-phase matching (QPM) in potassium titanyl phosphate (KTP) and lithium niobate (LN) waveguides designed for very low loss will be used to create frequency convertors at arbitrary source and tar ...

Bonded composite materials offer considerable opportunity to reduce manufacturing cost, improve structural performance, and improve fuel efficiency of aircraft. However, bonded composite aircraft structures continue to be a challenge to manufacture due to the certification requirement to determine the strength of the bonds in the structures - before they are placed into service. Current testing te ...

This project develops a nutrition program, MenuChoice©, for community-based group homes for persons with intellectual or developmental disabilities (IDD). Adults with IDD experience poorer nutritional health and more nutrition-related secondary conditions than adults without disabilities. These conditions are preventable and modifiable through a safe, healthful diet, but multiple challenges precl ...

The accelerating prevalence of antibiotic-resistant bacterial strains is an increasing public health problem. While the emergence of resistant strains is unavoidable, it is exacerbated by the widespread use, inappropriate prescription and misuse of antibiotics. Development of new antibiotics is slow and costly. One alternative to antibiotics is the development of antimicrobials that target the bac ...

Army quantum information researchers have an immediate need for improved stable, narrowband violet and UV laser sources with 10–100 mW output and 10 MHz–10 GHz tuning. These sources are required for numerous ion and atom qubits functions including photoionization, Doppler cooling, state initialization, and detection. The cost and complexity of currently available UV lasers hampers current ef ...

We propose to design a prototype device based on coherent accumulation and interference of spectrally shaped waveforms to achieve wideband optical arbitrary waveform generation with time apertures of 50 us, complete control of phase and amplitude, bandwidths of 100 GHz up to 1 THz, and a spectral resolution of 50 kHz. This technology enables wideband agile waveform generation for communications, ...

The majority of students and educators would probably agree that students are better able to grasp scientific concepts from the use of hands-on activities and other inquiry-based educational practices than from typical lecture problem solving methods. Anasphere, Inc is working to make inquiry based tools and materials for weather and climate education more readily available for students and educat ...

In an attempt to extend turbine engine on-wing time, thermal barrier coatings (TBC) using various application techniques have been developed. High temperatures corrosion due to penetration of chemically active species along the columnar grains of the topcoat limits the durability of TBCs. This results in degradation of the topcoat thermal insulation ceramic layer and accelerated oxidation of the b ...

In support of the DARPA efforts focused on delivering higher thrust-to-weight ratios, reduced cost turbine engine technology as well as developing innovative and high Mach airbreathing engines, MSE Technology Applications, Inc., with the Air Force ResearchLaboratory, proposes to design, develop, and test a new high Mach engine concept, the SteamJet(TM), which is based on existing turbojets. This ...
