The industrialization and urbanization movements have resulted in air pollutants being commonplace in industrial and residential areas; pollutants are produced by automobiles, manufacturing processes, and home improvement, among other activities. Air toxics pose a significant risk to public health and lower quality of life due to both acute and chronic health impacts. Therefore, there is a need fo ...

VISIMO’s ML Toolkit for Grey Literature Screening will reduce bias in, and improve accuracy of, systematic reviews (SRs) for chemical risk assessment. Grey literature is notoriously difficult to screen and tag, and despite its importance, researchers often exclude grey literature from their SRs due to necessity. VISIMO’s Toolkit will enable researchers to filter full documents of all types and ...

During this Phase II SBIR research project, Ohio Lumex will complete development of a sorbent trap method for continuous emissions monitoring of metal hazardous air pollutant (HAP) emissions. If method sensitivity is sufficient and the method is approved by EPA, it may also be used as an alternative to Method 29 for short-duration testing. Metal HAP emissions from stationary sources are currently ...

To enable fast and robust bias modulators for gyrotrons used in the nuclear fusion systems, GaNify LLC will develop a power switch capable of switching 50-kV and 1-A within 1 µs, without the need of series-stacking. This new technology will significantly reduce the circuit complexity and shorten the modulation voltage rise time. The new 50-kV power switch is based upon the demonstrated 10-kV gall ...

During this Phase I SBIR research project, Ohio Lumex will develop a sorbent trap method for continuous emissions monitoring of metal hazardous air pollutant (HAP) emissions. If this method is promulgated by EPA, it may also be used as an alternative to Method 29 for short-term testing. Metal HAP emissions from stationary sources are currently determined using emissions factors derived from interm ...

The COVID-19 pandemic caused by SARS-CoV-2 has exposed weaknesses in society’s ability to rapidly respond to a global public health problem. SARS-CoV-2 and variants are highly contagious and can cause mild to extremely severe disease and death. It is believed that the main route for transmission is aerosol droplets naturally discharged from an infected person. XCMR is developing breakthrough res ...

As the single largest consumer of materials and energy use worldwide, the construction sector remains a prime target for materials reuse reform. (Krausmann et al., 2009; De Ia Rue du Can & Price, 2008). Construction and ongoing operation of the built environment extracts a significant amount of resources -- and on an ongoing basis. According to the U.S. Green Building Council (USGBC), buildings ac ...

This project will develop an engineered soil product and process that repurpose waste-stream glass into soil suitable for horticultural and green infrastructure projects. The project supports the EPA's goal to improve sustainable materials management. Recycling of solid waste materials, like glass, remains challenging to cities due to costs of recycling in comparison to landfill disposal. Process ...

GaNify LLC will develop 10-kV 10-A power diode prototypes for medium-voltage power electronics systems. The medium-voltage power diodes are based on a novel charge-balanced GaN super-heterojunction technology, which already demonstrated ~2X higher effective E-field, scalability to over 10 kV, and ~3X lower on-resistance over the existing wide bandgap semiconductor technology. This project will stu ...
