Evaluation of a Particle Sampling Probe to Measure Mass Concentration in Particle-Laden Flows
Particle ingestion is a prevalent issue for jet engines. During operation, sand and ash particles enter the engine and can cause serious problems, including erosion and buildup of Calcia-Magnesia-Alumina-Silicate (CMAS) deposits. Analyzing the particle mass concentration of the airflow can help …

Toxicity of manufactured particulate materials on plant root growth
The rapid development of particle technology and the growing use of particulate materials in industries are bringing large amounts of manufactured particles into the environment. Epidemiological studies suggest that fine particles (particles with aerodynamic diameter smaller than 2.5 um, i.e., …

Experimental Investigation of Gaseous Oxyacetylene Blast Enhancement by the Combustion of Suspended Multimodal Spherical Aluminum Powder
… the combustion of non-uniform-sized aluminum particles. These multimodal aluminum powders consisted of a 50/50 mixture by mass of larger (~30 μm) and smaller (~1-10 μm) particles. Experiments were conducted at the large-scale Virginia Tech Shock Tube Research Facility to measure blast …

The application of low-cost sensors to monitor and characterise particulate matter air pollution
… networks have been established to record particle mass concentrations under fixed conditions. However, monitoring sites are sparsely distributed due to the expense, size and calibration requirements of regulatory-grade instruments. Very limited information is available on the particle …

Assessment of nanoparticle emission of polypropylene, polyester and epoxy nanocomposites during automated drilling process.
… exposure, or the impact of embedded nanoparticles in commercial composites when they are released during machining processes. In this thesis, four groups of nanocomposites are identified as being used within industry and having potentially-harmful nanoparticles - the nanocomposites …

Chemoprevention of Lung Carcinogenesis: Aerosol Administration and Deposition in the Mouse Lung
… administration depends on many factors such as particle size distribution, total particle mass concentration, and the physiochemical properties of drug particles. Genetically-engineered mice play an important role in drug screening and preclinical studies. However, because mice have much smaller …
