Lung function and self-rated symptoms in healthy volunteers after exposure to hydrotreated vegetable oil (HVO) exhaust with and without particles

Particle and Fibre Toxicology, 2022
Background Diesel engine exhaust causes adverse health effects. Meanwhile, the impact of renewable diesel exhaust, such as hydrotreated vegetable oil (HVO), on human health is less known. Nineteen healthy volunteers were exposed to HVO exhaust for 3 h in

Polydatin ameliorates ovalbumin‐induced asthma in a rat model through NCOA4‐mediated ferroautophagy and ferroptosis pathway

FEBS Open Bio, EarlyView.
In this research, a rat model of asthma was created using OVA, and polydatin served as an intervention. By inhibiting ferroautophagy mediated by NCOA4 and averting ferroptosis, polydatin has been demonstrated to reduce asthma. This work presents new ideas for investigating the mechanism of polydatin's ability to alleviate asthma, in addition to ...

Chemical Composition of Gas- and Aerosol-Phase Products from the Photooxidation of Naphthalene [PDF]

, 2010
The current work focuses on the detailed evolution of the chemical composition of both the gas- and aerosol-phase constituents produced from the OH-initiated photooxidation of naphthalene under low- and high-NO_x conditions.

A Comprehensive Review of Additive Manufacturing for Space Applications: Materials, Advances, Challenges, and Future Directions

Advanced Engineering Materials, EarlyView.
Additive manufacturing (AM) transforms space hardware by enabling lightweight, high‐performance, and on‐demand production. This review outlines AM processes—powder bed fusion (PBF), directed energy deposition (DED), binder jetting (BJ), sheet lamination (SL), and material extrusion (ME)—applied to propulsion, satellite structures, and thermal devices ...

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

Aerosol 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

Advanced 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.
