Iron Solubility Related to Particle Sulfur Content in Source Emission and Ambient Fine Particles
Environmental Science & Technology, 2012The chemical factors influencing iron solubility (soluble iron/total iron) were investigated in source emission (e.g., biomass burning, coal fly ash, mineral dust, and mobile exhaust) and ambient (Atlanta, GA) fine particles (PM2.5). Chemical properties (speciation and mixing state) of iron-containing particles were characterized using X-ray absorption

Relationship Between Particle Shape and Void Content of Fine Aggregate
Cement, Concrete, and Aggregates, 2004Abstract Fine aggregate characteristics have an important influence on water demand and related properties of concrete. Several test methods for measurement of fine aggregate angularity are reported in the literature. These tests typically provide a single number that represents the bulk, or average angularity of the sand.

The influence of the fine particle content of the flow behaviour of bulk materials
Powder Technology, 1984Abstract Experimental results obtained from shear tests with well defined mixtures of coarse grained (= cohesionless) and fine grained (= cohesive) materials are presented. Evaluation of the experiments with respect to parameters based on considerations of particle interactions results in a meaningful interpretation of the observed material behaviour.

Effect of Particle Shape and Fine Content on the Behavior of Binary Mixture
Journal of Engineering Mechanics, 2017AbstractThe behavior of binary granular mixture is studied by the discrete element method. This granular material contains large and small particles that are similar ellipsoids of different sizes. The size ratio of the major-axes of the large and small ellipsoids is 5.

Abstract Removing solid particles from ethanolic corn extracts by gravitational settling into a water layer has been studied as part of a project to develop a low cost method to extract ethanol-soluble protein from corn meal. Settling has several advantages over industrially proven methods of liquid/particle separation: (1) less expensive equipment; (

Effects of Particle Size and Fines Content on Thermal Conductivity of Quartz Sands
Transportation Research Record: Journal of the Transportation Research Board, 2015The thermal properties of soil have drawn great research attention in recent years. Thermal conductivity is the most important such property, particularly for the design of shallow geothermal systems such as energy piles and borehole thermal energy storage.

Effects of abraded fine particle content on strength of quick-hardening concrete
Cement and Concrete Composites, 2019Abstract The strength of quick-converting railway tracks is expected to be lower due to abraded fine particles attached to the surface of ballast aggregates caused by gravel friction under repetitive train loading. The effects of abraded fine particle content on the failure process of quick-hardening concrete were investigated using digital image ...

Atmospheric Environment, 1998
Abstract Chemical components of atmospheric fine particles (aerosols less than 2 μm in diameter) were measured every half month in Sapporo from November 1991 to October 1992. Water content of the particles was, in particular, analyzed with Karl Fischer method as well as elemental carbon, organics, sulfate, nitrate, chloride, ammonium, sea-salt ...

Increasing The Fine Particle Content In Metal Powders For LPBF Through Nanoparticle Dry-coating
World PM2022 Proceedings, 2022In powder-bed-based additive manufacturing (AM) processes, such as laser powder bed fusion (LPBF) typically the fine particles (less than 20 µm) are removed from metal powders in order to decrease powder cohesion that often results in inhomogeneous powder spreading.
