Measuring aerosol size distributions with the aerodynamic aerosol classifier [PDF]

open access: yesAerosol Science and Technology, 2018
The Aerodynamic Aerosol Classifier (AAC) is a novel instrument that selects aerosol particles based on their relaxation time or aerodynamic diameter. Additional theory and characterization is required to allow the AAC to accurately measure an aerosol's aerodynamic size distribution by stepping whilst connected to a particle counter (such as a ...

Surface Modification of Fluorine‐Free Superhydrophobic Materials with (Ultra‐)Thin TiO2 Layers

open access: yesAdvanced Engineering Materials, EarlyView.
Significant changes in wettability, with a reduction of 60o in the water conduct angle, are reported via the surface modification of fluorine‐free superhydrophobic thin films, prepared by aerosol‐assisted chemical vapor deposition, after coating a 4 nm layer of titanium dioxide on the surface using atomic layer deposition.

A laminar flow model of aerosol survival of epidemic and non-epidemic strains of Pseudomonas aeruginosa isolated from people with cystic fibrosis [PDF]

open access: yes, 2008
Cystic fibrosis (CF) is an inherited multi-system disorder characterised by chronic airway infection with pathogens such as Pseudomonas aeruginosa. Acquisition of P. aeruginosa by patients with CF is usually from the environment, but recent studies have

Biomaterial Strategies for Targeted Intracellular Delivery to Phagocytes

open access: yesAdvanced Functional Materials, EarlyView.
Phagocytes are essential to a functional immune system, and their behavior defines disease outcomes. Engineered particles offer a strategic opportunity to target phagocytes, harnessing inflammatory modulation in disease. By tuning features like size, shape, and surface, these systems can modulate immune responses and improve targeted treatment for a ...
