The additive manufacture of metal components from powder feedstocki.e. the net-shape, three-dimensional forming of a component, layer by layer, from a computer filehas gained popularity in the last nearly three decades, evolving from a method of rapid prototyping to rapid manufacturing. These methods are inherently far-from-equilibrium and present a significant, economical method to fabricate bulk ...

This proposal aims at developing a material agnostic modeling and analysis capability to help understand the genesis of voids and wrinkles during the processing and curing of fibrous composites. It also develops a hierarchical framework to investigate the effects of these micromechanics defects on the interlaminar strength and fatigue life of curved composite structures. The overall effort is cate ...

The goal of this development effort is to provide warfighters with inexpensive methods to view geospatial intelligence information on a hand-held tablet through their sense of touch. This allows eyes-free and silent operation without generating light. This proposal deals with two surface haptic display technologies. Variable-friction displays create haptic effects by varying the coefficient of fri ...

Technical Abstract (200 word limit): While state-of-the-art microbolometers demonstrate impressive capabilities for low-cost uncooled long-wavelength infrared (LWIR) imaging, there is currently a need for low-cost, mid-wavelength infrared (MWIR) imaging systems capable of high performance with fast frame rates at high operating temperatures. HgTe colloidal quantum dot (CQD) focal plane arrays (FPA ...

Sivananthan Laboratories, Inc. and the University of Illinois at Chicago (UIC) will collaborate to develop a Monte Carlo (MC) transport simulation package for devices based on III-V Type-II superlattice (T2SL) materials into a commercial offering suitable for device design and evaluation.UICs existing, research-grade, ensemble MC transport code is predictive of carrier transport in T2SL materials, ...

The objective of this effort is to continue the development of a dual-color MWIR display suitable for use in IR scene projection using a combination of quantum dot (QD) technology and commercial LCD displays. More efficient MWIR emitting core/shell QDs will be developed and fine-tuned during Phase II. The MWIR QDs will be deposited and patterned on a substrate to form 2-color subpixel arrays and t ...

Metal-organic frameworks (MOFs) are adsorbents that show promise in toxic chemical remediation, medical oxygen storage, high-value gas recovery, and multiple other military and civilian applications. However, a lack of quality-controlled supply limits these materials to laboratory environments. This work will borrow from industrial Quality practices to ensure supplied material conforms to specific ...

Natural fiber welding (NFW) is a disruptive bioengineering platform that has broad applications to manufacturing high performance materials and composites from abundant natural materials. By careful control of NFW process conditions, native order and structure of biopolymers is retained thus creating strong composites without glue while preserving the impressive native physical characteristics of ...

We will develop chip-scale components at 780/795 nm, for a superluminal ring laser gyroscope and accelerometer (SRLGA) using Rubidium.The components include high-power and narrow-band lasers, modulators, detectors, low-loss waveguides, and micro-resonator based magneto-optic isolators, integrated on a single chip. The components will be built on GaAs substrate.GaAsP Quantum Wells (QWs) will enable ...

Thermal batteries are single discharge reserve batteries that provide very long shelf life, minimal self-discharge, wide storage temperature range, fast activation under sudden power demand, and also wide range of temperature operating conditions. Such unique properties among electrochemical power systems are provided with application of molten salt electrolyte, which is in solid form under normal ...
