"US Armys combat uniform systems currently use NyCo fabrics which are made using a 50% nylon/50% cotton blend. Army Combat Utility (ACU) uniforms have excellent comfort and durability but lack flame resistance (FR). The US Army relies on expensive FR fabrics for protecting warfighters against fire hazards. These FR fabrics are typically made using specialty fibers such as Lenzing FR rayon fibers a ...

The low density of magnesium makes it of interest for the development of advanced materials having high specific strength and stiffness. Current Mg applications, however, are limited by the performance and cost/quality relationships of existing Mg-alloy systems. One approach to obtain improved Mg alloys is through the development of new alloys and/or Mg-based composite materials that are enabled t ...

The Defense Threat Reduction Agency (DTRA) has been supporting research of energetic materials and incendiaries as payloads for weapons to defeat targets containing chemical and biological agents. Several universities and Navy labs have been involved in this research, and have narrowed down on a few material formulations that are efficient biocides. These formulations contain a chemical ingredient ...

Objectives and Intellectual Merit: The infrastructure of modern civilization is a set of complex systems1 that dynamically interact across multiple layers of abstraction. Researchers from many disciplines2 are designing analytical tools for predicting the global and local behaviors of these complicated, multi-layer networks. Easily usable, available (open source) and inter-operated tools are neede ...

With missions surrounding counterproliferation, nonproliferation and WMD reduction, the stakes for DTRA are incredibly high. Effectively conducting this work involves cooperation and coordination across a wide range of military and government organizations throughout the United States and the world. The decentralization of threats has led to an explosion in the sources and types of data needed to ...

Terrorist use of radioactive nuclear materials via nuclear and/or radiological dispersion devices (dirty bombs) is a serious threat. Therefore, it is critical to detect the proliferation of nuclear material. Critical challenges facing this objective include: (a) high sensitivity detection of signature emissions (e.g., gamma rays) from common radioactive isotopes behind shielding, and (b) cost-effe ...

The development of a high fidelity, generalized computational framework with the necessary physical submodels incorporated for the analysis of multiphase, combusting, internal and external ballistic flows is proposed. The focus in Phase I will be developing a framework based on an existing unstructured multi-element, fully implicit, CFD code to provide an end-to-end analysis capability for interna ...

In this STTR project, EMAG Technologies Inc. and the University of Michigan have joined forces to propose the development of a visual software tool for stochastic analysis of coupled electromagnetic and circuit problems often encountered in EMC/EMI scenarios. The proposed tool will integrate novel and computationally efficient uncertainty quantification (UQ) algorithms with EMAG's commercial EM an ...

There is an unmet demand for nano-scaled ultra-low-power low-cost radios to address field-deployable and massively producible sensing and communication networks in future military and commercial applications. To overcome the limitations in existing bulky and power hungry radios, we propose a disruptive solution by exploiting the holistic integration of THz radio transceiver system, on-chip antenna ...

We will design, fabricate, and characterize an ion microtrap equipped with an integrated in-situ cleaning capability and with integrated optical access ports. The trap will be made of optical quality fused silica. The trap design and the fabrication process will allow for future developments, such as the addition of an integrated oven, UHV-maintaining subsystem, and rapid trap exchange with interc ...
