The proposed multi-spectral IFF beacon will use 40 to 50 % effient high power laser diodes at 863, 1064, and 1550 nm wavelengths. Thermal emitters including diamond-like carbon thin films, photonic crystals, and quantum cascade lasers will be characterized and compared. Finally a model to predict the detection range of IFF beacons will be developed using proprietary emitter power and atmospheric ...

A user-friendly software package for rapid fatigue evaluation of specific scalable flaw geometries, as well as stable tearing after crack length reaches a specified size, is being developed. The package will employ modified CRACK3D code and use VCCT with 10-noded tetrahedral elements to determine fatigue crack tip parameters (e.g. dK1, dK2, etc.) for fatigue cracks undergoing (a) mixed mode, in-ph ...

The objective of this proposal is to demonstrate the feasibility and performance of compact, efficient, radiation hardened laser technology for LADAR detection, ranging and range-gated imaging applications. Traditional laser designs exhibit modest wall plug efficiencies. They are limited in scalability, tough to miniaturize and often intolerant of space radiation. Conventional diode pumped lase ...

Kigre proposes to develop and integrate unique radiation hardened, athermal, 1.5um laser gain materials and pumping architectures into high performance optical laser amplifier devices for SATCOM applications. The approach employs long life radiation tolerant pump diodes configured for direct side pumping of large mode area laser glass gain elements. Traditional single mode fiber laser amplifier ...

Microbial contamination in kerosene based aviation fuels has been a problem for the USAF since the 1960’s. Antimicrobial effect of earlier used fuel system icing inhibitor (FSII) became an initial solution to this problem, but later, such fuel additives were banned due to their extreme toxicity towards humans. Newer FSIIs, being more eco-friendly, do not possess the antimicrobial properties of ...

Biodiesel is our next generation eco

A major limiting factor to organic cell efficiency is exciton diffusion and charge transport, which depend on charge carrier mobility in the E-fields created internally by the device materials and structure. Versatilis proposes a novel approach to ultimately improving >10% the efficiencies realized by typical organic solar cells, whether

A major limiting factor to organic photovoltaic (OPV) solar cell efficiency is exciton diffusion and charge transport, which depend in turn on carrier mobility and the E-fields created internally by the device materials and structure. Versatilis proposes a novel approach to enabling the better OPV cells from leading OPV makers to reach >10% efficiencies, whether

This project addresses the problem of increasing biomass feed to electricity-generating power furnaces with the goal of reducing GHGs. Currently wood pellets are burned, but the ash content and lower energy density limit their use. Lignin pellets have approximately the same energy content as coal, about 12,000 Btu/lb, which is about twice the energy of low-moisture wood pellets. The lignin pell ...

This project allows pulp and paper mills to extract a purified lignin stream from their recovery process. By making up the fuel value of this extracted lignin the mill remains carbon neutral. A power company that can replace coal with lignin achieves a significant GHG reduction. The sequential liquid lignin recovery and purification process enables a paper mill to recover lignin from their black l ...
