Contribution of Particulates to Airborne Disease Transmission and Severity: A Review.

Environmental Science and Technology
The emergence of coronavirus disease 2019 (COVID-19) has catalyzed great interest in the spread of airborne pathogens. Airborne infectious diseases are classified into viral, bacterial, and fungal infections.

A review of the in vivo and in vitro toxicity of silver and gold particulates: Particle attributes and biological mechanisms responsible for the observed toxicity

Critical Reviews in Toxicology, 2010
This review is concerned with evaluating the toxicity associated with human exposure to silver and gold nanoparticles (NPs), due to the relative abundance of toxicity data available for these particles, when compared to other metal particulates. This has

Non-pollen particulates in honey and sugar

Food Additives and Contaminants Part A-chemistry Analysis Control Exposure & Risk Assessment, 2013
A total of 19 honey samples, mostly from Germany but also from France, Italy, Spain and Mexico, were analysed for non-pollen particulates. Only coloured fibres and fragments were quantified.

Airborne Particulates in the OR Environment

AORN Journal, 1999
ABSTRACTIntraoperative sampling of airborne particulates is rarely performed in teh OR environment because of technical difficulties associated with sampling methodologies and because of the common belief that airborne contamination is infrequently associated with surgical site infections (SSIs).

Instant visual detection of trinitrotoluene particulates on various surfaces by ratiometric fluorescence of dual-emission quantum dots hybrid.

Journal of the American Chemical Society, 2011
To detect trace trinitrotoluene (TNT) explosives deposited on various surfaces instantly and on-site still remains a challenge for homeland security needs against terrorism. This work demonstrates a new concept and its utility for visual detection of TNT

Receptivity of a supersonic boundary layer to solid particulates

Journal of Fluid Mechanics, 2013
Laminar–turbulent transition in the boundary layer at supersonic speeds can be initiated by small solid particles present in the free stream. Particulates interacting with the boundary-layer flow generate unstable wavepackets related to Tollmien ...
