Effective Improvement of Pt Catalyst for Exhaust Gas Purification by Using the Highly Crystallized CeO₂ as an Additive

Over the last few decades, Pd-based three-way catalysts (TWCs) have been more extensively used than Pt-based TWCs because of their higher thermal stability. In this study, the addition of CeO₂ to a Pt-based TWC w...

Experimental and BEf-scaled cross sections for electron-impact excitation of ammonia molecules from near threshold to high-intermediate energy

Absolute differential and integral cross sections (DCSs and ICSs) for the lowest-lying singlet excitations in ammonia (NH₃) molecules have been measured from near threshold to 400 eV using angle-revolved electron...
