Rethinking the formation and growth of polycyclic aromatic hydrocarbons (PAHs), key contributors to harmful soot particles formed during fuel combustion and the smallest dust grains in interstellar ...

(Nanowerk News) Soot is one of the world’s worst contributors to climate change. Its impact is similar to global methane emissions and is second only to carbon dioxide in its destructive potential.

A team of researchers from ETH Zurich has used simulations on the CSCS supercomputer "Piz Daint" to investigate how ageing mechanisms of soot particles in the atmosphere affect cloud formation. The ...

Biofuel reduces soot particle emissions during cruising Reducing the emissions of soot particles reduces the climatic impact of contrails Results of joint DLR / NASA research flights, which were ...

Aircraft emissions are associated with all sorts of environmental problems. Researchers have long been studying the different kinds of emissions in order to understand how air transport is altering ...

Q. When we had our condo built about ten years ago, we had a gas log fireplace installed. This is not one of the newer enclosed units with an exhaust on the exterior of the building. Ours has a full ...

Analysis of in-flight emissions from an Airbus A350-900 using 100% sustainable aviation fuel indicates a reduction of 35% in soot particle numbers, and a halving of contrail ice-crystal formation per ...
