An investigation into the fertilizer particle dynamics off-the-disc [PDF]

open access: yes, 2015
The particle size range specifications for two biosolids-derived organomineral fertilizers (OMF) known as OMF10 (10:4:4) and OMF15 (15:4:4) were established.

Particle Size and Pore Size Selection on Ordered Mesoporous Silica [PDF]

open access: yes, 2023
Controlling both particle size and pore size is critical when using mesoporous silica for fundamental studies. Pore size can be adjusted by modifying the reaction conditions during synthesis, but achieving a narrow particle size selection can be ...

Size-resolved particle number emissions in Beijing determined from measured particle size distributions [PDF]

open access: yesAtmospheric Chemistry and Physics, 2020
The climate and air quality effects of aerosol particles depend on the number and size of the particles. In urban environments, a large fraction of aerosol particles originates from anthropogenic emissions.

Intrinsic speckle noise in in-line particle holography due to poly-disperse and continuous particle sizes [PDF]

open access: yes, 2000
In-line particle holography is subject to image deterioration due to intrinsic speckle noise. The resulting reduction in the signal to noise ratio (SNR) of the replayed image can become critical for applications such as holographic particle velocimetry ...

Preferential attachment of Escherichia coli to different particle size fractions of an agricultural grassland soil. [PDF]

open access: yes, 2007
This study reports on the attachment preference of a faecally derived bacterium, Escherichia coli, to soil particles of defined size fractions. In a batch sorption experiment using a clay loam soil it was found that 35% of introduced E.

Effect of particle size and particle size distribution on the post-liquefaction strength of granular soils

open access: yesSoils and Foundations, 2023
In practice, post-liquefaction strength is largely determined from case histories, but the case history database is limited and there are gaps in the information available in each case.

Characterization of Particle-Size-Based Homogeneity and Mycotoxin Distribution Using Laser Diffraction Particle Size Analysis

open access: yesToxins, 2023
Sample homogeneity dictates whether analyzing a test portion of an entire sample can provide representative information about incurred mycotoxins. In this study, we evaluated particle-size-distribution-based homogeneity of laboratory mycotoxin samples ...

A practical primer for image-based particle measurements in microplastic research

open access: yesMicroplastics and Nanoplastics, 2023
Microplastics have been detected in large numbers around the world. Not only their sheer number threatens ecosystems, their biodiversity, and human health, but risks are also posed by particle characteristics such as size and shape.
