New electrolyzer turns plastic-waste syngas into ethylene with less energy
For every ton of ethylene created, one ton of carbon dioxide is produced. With more than 300 million tons of ethylene produced each year, the production system has a huge carbon footprint that scientists and engineers are eager to reduce and eventually eliminate. A new device developed in Ted Sargent's lab at Northwestern takes a step toward breaking that cycle.

Just back from a demo of the XPS! #Chemistry

A floor standing instrument labeled Thermo Scientific and K-Alpha. Part of it is a sizable stainless steel vacuum chamber in which the sample is irradiated w X-rays, and the energies of ejected electrons are measured.
