The final product is Cyberchase Fractions Quest—a math game based on the storyline of PBS children's television series, Cyberchase. In the game, students in grades 3 and 4 will apply learning fractions within three contexts: areas and regions (such as shapes), sets (groups of objects), and on a number line. The game will identify specific areas where students struggle and will introduce challeng ...

Novel photonic structures, such as periodic metal-dielectric photonic bandgap structures (MDPBG) have the potential to revolutionize the field of optical windows. The large mismatch in the permittivities of the metal and dielectric creates resonant tunneling, which allows for high transmission in regions where metals are typically opaque. This property makes MDPBGs very attractive for screening or ...

Wireless sensors are an extremely effective means of communication on the modern battlefield, however current battery technologies have limited the full realization of these essential tools. A robust, high efficiency, light weight, flexible power source is thus critical for effective deployment of modern technologies. Organic-inorganic hybrid perovskites (OIHPs) are the ideal candidates for use in ...

We propose to develop highly-sensitive low size, weight, and power (SWaP) chip-scale mid-infrared integrated-optic sensors for trace gas measurements, We will combine Tunable Diode Laser Spectroscopy (TDLAS) detection techniques with narrow-linewidth fast-tuning Distributed Feedback (DFB) Quantum Cascade and Interband Cascade Lasers (QCLs and ICLs) to create a platform for a family of sensors, ea ...

Composites are being adopted increasingly in aerospace structures due to their superior specific stiffness and strength, their resistance to fatigue and ability to greatly reduce part count. They present additional challenges for design however, due to their heterogeneity and anisotropy, and for inspection since damage often occurs beneath their surface. Currently successful laboratory non-destru ...

Nano Terra will collaborate with the Center for Drug Discovery (CDD) at Northeastern University, to develop a sensor capable of detecting synthetic cannabinoids independently of their specific molecular structure. The sensor will be portable, label-free and most-importantly shelf stable. Our proposed sensor will employ a structurally stabilized mutant CB1 receptor as the recognition element in fl ...

The objective of this effort is to develop a dual-color MWIR display suitable for use in IR scene projection using a combination of QD technology and commercial LCD displays. Efficient MWIR emitting core/shell PbSe/PbS(or CdSe) QDs will be focused on during Phase I. MWIR QDs will be produced and deposited on a substrate to combine with a grayscale output LCD microdisplay. The light produced by ...

Physical Sciences Inc. in cooperation with University of Notre Dame proposes to develop a method for the persistent surveillance and detection of aerosolized biological warfare agents using a distributed point bioaerosol detector network, local meteorological sensors, existing infrared surveillance cameras, and crowdsourced georeferenced network traffic and phrase monitoring. The proposed technolo ...

Physical Sciences Inc., in cooperation with Boston University, proposes to develop an Interferometric Reflectance Imaging Sensor (IRIS) to detect waterborne pathogens including E. coli for use with military mobile water treatment systems. The imaging platform will employ an algorithm to discriminate E. coli based on size/shape analysis concurrent with capture probes with application to multiplexe ...

The purpose of this proposal is to additively manufacture (AM) smart structures with embedded electronics such as sensors, accelerometers, antennas, etc. The goal of these smart structures will be to enhance the effectiveness and survivability of the Armys ground systems. The use of additive manufacturing smart structures provides flexibility in the materials used and the functionality of the elec ...
