Manufacturing of Portland cement, the primary binder in concrete, accounts for ~7% of global CO2 emissions, 4% of energy use, and exhaustion of natural resources. Premature aging of concrete in infrastructure systems is another major concern.  A robust binder chemistry has been developed to overcome these drawbacks.  The original approach to production of this binder, however, is not compatible ...

Chemical and biological (CB) warfare agents are a serious threat to our soldiers and national security. Different warfare agents and microbes may be delivered using solids (powders, particulates, ice crystals), hydrosols (air borne liquid droplets), or aerosols (air-born particulates). Solids, hydrosols, or aerosols can penetrate, accumulate, and transport through both porous and non-porous surfac ...

An electromagnetic pulse (EMP) attack could cause widespread outage of the commercial electric power system that could last for weeks to months. Microgrids for defense critical infrastructure (DCI) should thus be equipped to operate in islanded mode for extended periods of time using only local fuel storage and renewable energy sources. The primary difference between operating a microgrid in islan ...

Per- and Polyfluoroalkyl Substances (PF AS) have been widely used in everyday consumer products. Landfills are the final repository for the PF AS-containing products and wastes, and consequently, one of the major sources of PF AS to the environment. Elevated concentrations of PFAS in leachate have raised concerns regarding disposal of leachate. Yet, cost-effective treatment technologies for PF AS ...

Antibiotic resistant bacteria have become a major concern in discharges from hospitals, wastewater treatment plants, and agricultural runoff. A quick, inexpensive, field- deployable method of detecting antibiotic resistant bacteria in these waters is desirable. Antibiotic resistant bacteria of concern include Salmonella, Staphylococci, E. coli, Enterococci, and coliform bacteria, among others. A p ...

Check-in Check-out (CICO) is a widely used behavioral intervention for elementary and middle schools centered on goals, feedback, and communication with parents about daily behavioral performance. This project will develop a prototype platform to streamline and automate the delivery of CICO. The prototype will include an app, a user-friendly interface, and a dashboard to track progress and capture ...

In a previous National Science Foundation SBIR project, the developer created an online platform that uses songs to support mathematical learning. In the current project, the team will develop a prototype of a component of a platform to guide students in creating and producing their own music videos about algebra. The prototype will include a video production application, features to enhance learn ...

This project will develop an augmented reality application to generate personalized formative assessment feedback as students interact with physical objects related to STEM (science, technology, engineering, and math) concepts, such as recognizing the shape of an atom. The prototype will be designed as a multi-sensory tool to support students with visual challenges. At the end of Phase I, in a res ...

Handheld radioisotope identification instruments (RIIDs) are an important, front-line tool for passively detecting, locating, and characterizing radioactive materials and thereby helping to prevent the spread of illicit nuclear materials. Border patrol, customs, and law enforcement personnel, along with warfighters, demand an enhanced, more sensitive RIID capable of integrated gamma and neutron de ...

While aluminum casing materials provide some enhanced performance and thermal loading to explosive ordinance, their overall effectiveness is highly limited by incomplete combustion and long residence times. In order to reduce these problems, the casing material must be designed to facilitate rapid fragmentation through either specialized casing geometries or greatly refined initial particle sizes. ...
