RNA control of HIV-1 particle size polydispersity. [PDF]

open access: yesPLoS ONE, 2014
HIV-1, an enveloped RNA virus, produces viral particles that are known to be much more heterogeneous in size than is typical of non-enveloped viruses. We present here a novel strategy to study HIV-1 Viral Like Particles (VLP) assembly by measuring the ...

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.

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.

Large-scale frictionless jamming with power-law particle size distributions [PDF]

open access: yes, 2022
Due to significant computational expense, discrete element method simulations of jammed packings of size-dispersed spheres with size ratios greater than 1:10 have remained elusive, limiting the correspondence between simulations and real-world granular materials with large size dispersity.

Adiponectin and Lipoprotein Particle Size [PDF]

open access: yesDiabetes Care, 2009
OBJECTIVE Adiponectin has been postulated to affect lipid and insulin signal transduction pathways. We evaluated the relationships of plasma adiponectin with lipoprotein mean particle size and subclass concentrations, independent of obesity and insulin sensitivity ...
