Reduction of nitrogen oxides by injection of urea in the freeboard of a pilot scale fluidized bed combustor [PDF]

open access: yes, 1989
The ‘thermal deNOx’ process using urea has been investigated in a 1 MW fluidized bed combustor. NOx reductions of up to 76% were obtainable by using this method. The experimental results show that urea is at least as active as NH3, which is commonly used

Metal–Organic Frameworks for Gaseous Pollutant Management: From Capture to Neutralization and Reutilization

open access: yesAdvanced Functional Materials, EarlyView.
This review maps how MOFs can manage hazardous gases by combining adsorption, neutralization, and reutilization, enabling sustainable air‐pollution control. Covering chemical warfare agent simulants, SO2, NOx, NH3, H2S, and volatile organic compounds, it highlights structure‐guided strategies that boost selectivity, water tolerance, and cycling ...

Pulmonary Endothelial Cell NOX [PDF]

open access: yesAmerican Journal of Respiratory Cell and Molecular Biology, 2012
Reactive oxygen species (ROS) have profound influences on cellular homeostasis. In excess, they can potentiate the oxidation of numerous molecules, including proteins, lipids, and nucleic acids, affecting function. Furthermore, ROS-mediated oxidation of proteins can directly or indirectly modulate gene expression via effects on redox-sensitive ...

Nitric Oxide Mediates Biofilm Formation and Symbiosis in Silicibacter sp. Strain TrichCH4B. [PDF]

open access: yes, 2015
UnlabelledNitric oxide (NO) plays an important signaling role in all domains of life. Many bacteria contain a heme-nitric oxide/oxygen binding (H-NOX) protein that selectively binds NO.

Patient‐Derived 3D Bioprinted Cardiac Organoid Constructs Reveal Key Pathological Features of Duchenne Muscular Dystrophy

open access: yesAdvanced Healthcare Materials, EarlyView.
Patient‐derived cardiac organoids reveal key features of Duchenne muscular dystrophy cardiomyopathy, including apoptosis, oxidative stress, calcium handling defects, and mechanical remodeling. By integrating organoids into alginate–gelatin bioprinted constructs, disease phenotypes are organized into scalable 3D cardiac tissues displaying extracellular ...

Sensitivity to grid resolution in the ability of a chemical transport model to simulate observed oxidant chemistry under high-isoprene conditions [PDF]

open access: yes, 2016
Formation of ozone and organic aerosol in continental atmospheres depends on whether isoprene emitted by vegetation is oxidized by the high-NOx pathway (where peroxy radicals react with NO) or by low-NOx pathways (where peroxy radicals react by alternate
