7/18/2016 - Contracts and cooperative agreementsA contract to develop a liquid crystal (LC)-based nitrogen dioxide monitor housing a sensor which will detect and trigger an audio-visual alarm to warn miners when the concentration of nitrogen dioxide levels exceeds the threshold limits.
7/16/2016 - Contracts and cooperative agreementsA contract to assess four types of existing technology that can be applied to seals in a nondestructive manner under experimental conditions, including radio frequency sensing, ultrasonic sensing, ground penetrating radar, and tracer gas methods.
5/23/2016 - Contracts and cooperative agreementsA contract to design composite sensing materials to develop a sensor that is sensitive to carbon monoxide and nitrogen dioxide at the desired concentrations but is not affected by the interferences present in mines.
Effects of Hydrotreated Vegetable Oil on Emissions of Aerosols and Gases from Light-Duty and Medium-Duty Older Technology Engines4/1/2016 - Peer reviewed journal articlesThis article by NIOSH describes a study conducted to assess the potential of hydrotreated vegetable oil renewable diesel (HVORD) as a control strategy to reduce exposure of workers to diesel aerosols and gases.

Quantification of Optical and Physical Properties of Combustion-Generated Carbonaceous Aerosols (less than PM2.5) Using Analytical and Microscopic Techniques3/1/2015 - Peer reviewed journal articlesAn article describing experiments conducted to quantify and characterize the optical and physical properties of combustion-generated aerosols during both flaming and smoldering combustion of three materials common to underground mines.
2/6/2015 - Contracts and cooperative agreementsA contract to develop a “smart” self-contained open circuit breathing apparatus (SCBA) that protects against threat gasses and provides an extended duration of life-sustaining oxygen inhale stream by monitoring the surrounding atmosphere.
10/11/2014 - Contracts and cooperative agreementsA contract to provide miners with real-time alerts to potentially harmful air contaminants if a dangerous threshold of either immediate or timed exposure is detected.
10/1/2014 - Peer reviewed journal articlesA study assessing heavy-duty haulage trucks' contribution to the concentrations of aerosols and criteria gases in underground mine air and the physical properties of those aerosols for three FAME biodiesel blends.
