Under the Microscope January 2024 Winner

Car Exhaust Particles

TEM imaging of car exhaust particles

READY, SET, MAGNIFY! We are kicking off Under the Microscope 2024 with some Transmission Electron Microscopy (TEM) images of car exhaust particles, suggested by Dr Tendai Dube.

Every month we ask for your suggestions of what you would like to see imaged using any our techniques with our public engagement initiative Under the Microscope!

These TEM images show the presence of soot particles which are the product of incomplete combustion of fuel. The particles, with a diameter ranging from 10 to 20 nm, have a structure consisting of a carbon core surrounded by layers of carbon (resembling nano-onions).

Imaging was conducted by Dr Michael Fay on the JEOL 2100F TEM.
