Here is the full list of non compounded words containing an "sz".
Abszeß - Adoleszenz - Disziplin - Eszett - Faszie - Faszination - Fluoreszenz - Koaleszenz - Konfiszierung - lasziv - Lumineszenz - Obszönität - omniszient - Oszillation - phosphoresziere - Plebiszit - Proszenium - Rekognoszierung - Rekonvaleszent - Szene - viszeral
Most of these actually are of latin origin. My favorite is obviously "Abszeß" - probably the only word in the german language that will show a non compounded co-existence of "sz" and "ß".
