Graspable Math Activities is web application that middle and high school students use on laptops and tablets to practice algebra and receive instantaneous feedback. Activities are based on an algebra notation technology that can promote procedural fluency while allowing students to focus on strategy and the connection between concepts and procedures. The team will produce a website that will inclu ...

Researchers will conduct a pilot study with a socio-economically and diverse sample of at least 500 high school students who will test the prototype ROI tool. The researchers will examine the feasibility and usability of the prototype, whether ROI information increases search and discovery for educational opportunities; whether having ROI information increases the likelihood of click-through rates ...

Hy-Tek Mfg. Co. Inc. (HMC) is proposing a new concept for military expeditionary shelters that is compact, lightweight, structurally robust and offers the rapid and easy installation and teardown logistics necessary to accommodate the fast paced, agile and highly mobile Expeditionary Military Force. The REMS concept developed by HMC is comprised of a simple articulating structural frame with integ ...

Natural fiber welding provides a unique strategy to impregnate fibers, threads, and fabrics with nanostructure materials such as MOFs. The procedure utilizes ionic liquids to slightly dissolve cellulosic structure of the material, making it loose and mobile. Then water is used to remove the ionic liquid, and upon the removal of the ionic liquid, the cellulose structures are comingled and bind to e ...

Paper Spray mass spectrometry (PSMS) has been developed and commercialized for analysis of fluid samples by mass spectrometry. PSMS provides advantages over existing analysis techniques by reducing sample preparation needs and incorporating the sample storage and sample introduction to a single consumable device that is disposed after analysis, thus eliminating cross contamination and/or cleaning ...

There is a developing need for a low-cost high performance eSWIR infrared detector technology that can operate at room temperature with a cutoff wavelength of 2.5 microns. Over the years, many new and innovative technologies have emerged that have made some progress towards this goal, but the gap between the quantum efficiency and cutoff wavelength with room temperature have been difficult to brid ...

The highest performing infrared (IR) detectors are fabricated from alloys of HgCdTe (MCT) grown by molecular beam epitaxy (MBE) on lattice-matched substrates. Although the best performing IR detectors, MCT-based imaging arrays exhibit higher than anticipated noise, especially random telegraph noise (RTN) that occurs in seemingly random sets of pixels. It is presently believed that RTN originates f ...

Field effect transistors (FETs) based on alloys of AlGaN are the current state of the art for the switching and amplification of radio frequency (RF) signals, as would be used in radio communications, RADAR systems, and power conversion and control devices. A significant problem preventing AlGaN-based devices from realizing their true potential is the presence of dislocation defects that result fr ...

The objective of this effort is to develop and demonstrate an intelligent, autonomous dc-ac distribution unit based on isolated power conversion technologies to support interconnection of dc sources and energy storage devices with an ac tactical microgrid featuring tactical power generation and load equipment. The unit specifically targets 60 kW, bi-directional power conversion and power/energy ma ...

Sivananthan Laboratories proposes to design an electron-beam induced current (EBIC) platform capable of performing high-resolution carrier lifetime, mobility and diffusion length measurements at point and extended defects in small-band gap semiconductor interfaces for infrared detectors. The proposed design includes a micro-electro-mechanical systems (MEMS)-based double-tilt heating stage and will ...
