Soot Particles: Exploring the Sorption Science Behind Jet Emissions

Jet engines, the powerhouse behind the aviation industry, are significant contributors to global emissions, impacting both the environment and human health. By combusting fuel to produce thrust for flights, these engines release a mix of carbon dioxide (CO2), water vapor, nitrogen oxides (NOx), volatile organic compounds (VOCs), and soot particles into the atmosphere. Generally, soot […]

Development and Optimisation of Aircraft Air Purification Systems: Noxious Organic Species Removal from Cabin Air

Overview Airborne pollutants can have negative physiological impacts on passengers and crew members in the short- and long-term, hence aircraft cabin air quality is very important to human wellbeing. Due to their detrimental effects on human health, volatile and semi-volatile organic compounds, also known as VOCs and SVOCs, must be eliminated from the cabin air. […]

Studying the Interactions of Harmful Volatile Organic Compounds with Soot Particles using Dynamic Vapour Sorption

Written by: Jon G. Bell ( Volatile organic compounds (VOCs), such as benzene and formaldehyde, are characterised by high vapour pressures and, therefore, can easily adsorb to the surface of airborne soot particles, accumulating at the vapour-solid soot interface, within pores, or between the carbon core turbostratic graphene layers. These VOC-loaded, nanometric particles are extremely […]

Virtual plenary meeting of the International Civil Aviation Organisation’s Environment Committee

Written by: Thomas Rötger Every three years in February, the UN International Civil Aviation Organisation (ICAO) holds the plenary meeting of its Committee for Aviation Environmental Protection (CAEP). Normally, this meeting gathers about 200 aviation experts representing the States and international organisations at the ICAO Headquarters for two weeks in snowy Montréal. Not surprisingly, the […]
