SBC: MILLENNITEK LLC Topic: A14AT011
A lightweight and man-portable 300W tubular solid oxide fuel cell is being developed that can operate directly from liquid fuels without the need for separate fuel processing. A novel freeze-casting approach is being used to produce the anode-supported cells with an integrated catalyst that prevents sulfur and carbon in the fuel from degrading the electrical performance over time. Solid oxide fuel ...STTR Phase II 2021 Department of DefenseArmy
Parallel Two-Electron Reduced Density Matrix Based Electronic Structure Software for Highly Correlated Molecules and MaterialsSBC: Q-CHEM INC Topic: A14AT013
The variational two-electron reduced-density matrix (v2RDM) method provides an effective framework for computer modeling of the electronic structure of complex molecules and materials that exhibit strong correlation effects. In Phase I and Phase II of this STTR we have demonstrated that the GPU-accelerated implementation of the v2RDM-based complete active space self-consistent field (v2RDM-CASSCF) ...STTR Phase II 2019 Department of DefenseArmy
SBC: TOYON RESEARCH CORPORATION Topic: A15AT013
The Global Positioning System (GPS) is vulnerable to radio-frequency (RF) sources of interference and must be defended through electronic protection (EP) measures such as anti-jam (AJ) and anti-spoof (AS). The Phase I effort investigated antenna, electronic, and algorithmic designs for systems capable of supporting direction-finding (DF) measurements while simultaneously performing anti-jam and an ...STTR Phase II 2017 Department of DefenseArmy
SBC: RADIATION DETECTION TECHNOLOGIES INC Topic: DTRA14B005
At the completion of the research and development effort a Li-foil multi-wire proportional counter (MWPC) neutron detector with more than 625-cm2 of active area will be included in a portable radiation detection system. The system is expected to outperform the standards set by the ANSI N42.53 standards, and gamma-ray rejection ratio (GRR) of 1.0x10-8 or better. A gamma-ray spectrometer for isotope ...STTR Phase II 2017 Department of DefenseDefense Threat Reduction Agency
SBC: MILLENNITEK LLC Topic: A14AT011
Solid oxide fuel cells have long suffered from degradation due to impurities in the fuel and complexities associated with dissimilar materials and high operating temperatures.This degradation lowers the usable cell power output and requires ancillary equipment for fuel sulfur removal and reformation.A unique microstructure for the tubular anode will be produced using a novel freeze-casting techniq ...STTR Phase II 2017 Department of DefenseArmy
SBC: NALAS ENGINEERING SERVICES INC Topic: DTRA14B001
Nalas Engineering and Johns Hopkins University collaborated in a Phase I STTR program to study reactive mixtures of HI3O8 and nanocomposite fuels previously developed by the Weihs Group. These fuel/oxidizer mixtures are uniquely able to simultaneously produce heat and biocidal iodine gas, a combination designed to destroy biological weapons. The team at Nalas focused on evaluating conditions for p ...STTR Phase II 2017 Department of DefenseDefense Threat Reduction Agency
SBC: ATTOLLO ENGINEERING, LLC Topic: A15AT001
As the warfighter is increasingly using more highly integrated instruments, e.g. a laser rangefinder (LRF) combined with a laser designator and an imager, the need to decrease the size of these components becomes more important.Compact small munition applications of rangefinders particularly place an emphasis on size of the optical front end.In order to make the transceiver more compact, special a ...STTR Phase II 2017 Department of DefenseArmy
SBC: Eureka Aerospace Topic: A14AT004
This proposal addresses the problem of PCSS/laser trigger integration using a single monolithic laser diode array, thus simplifying the entire optical delivery network necessary for efficient operation of PCSSs. The proposal constitutes a logical continuation of Phase I effort where the main focus was on the detailed design of the PCSS/laser diode array (LDA) integrated architecture. In Phase II ...STTR Phase II 2016 Department of DefenseArmy
SBC: Pranalytica, Inc. Topic: A14AT015
In response to the Army STTR Topic A14A-T015 solicitation for tunable high-power LWIR lasers for standoff detection applications, Pranalytica proposed to develop a compact, rugged and highly reliable wavelength tunable quantum cascade laser (QCL) module delivering over 5W of peak power and over 0.5W of average power in the spectral region spanning from 7 to 11m. The proposed approach is based on a ...STTR Phase II 2016 Department of DefenseArmy
SBC: NESS ENGINEERING, INC. Topic: A14AT004
The objective of this Phase II proposal is to continue the development of a Photoconductive Semiconductor Switch (PCSS) with an integrated optical trigger that can switch at least 30 kV, 1 kA, 20 ns pulses with jitter 108 shots. Ness Engineering, Inc. (NEI) and Texas Tech University (TTU) propose to utilize wide bandgap materials to demonstrate lock-on switching and allow much less optical trigger ...STTR Phase II 2016 Department of DefenseArmy
