Toward an improved causal test of network effects: Does alliance network position enhance firm innovation?

open access: yesStrategic Management Journal, Volume 46, Issue 4, Page 863-897, April 2025.

Raman Measurements in the Hydroformylation of Decene with Laser Powers of 1 mW in Ex Zones

open access: yesChemie Ingenieur Technik, Volume 97, Issue 3, Page 204-212, March 2025.
A Raman measurement system with an excitation power below 1 mW was developed for the measurement of the hydroformylation reaction of decene to undecanal. The Raman systems can meet the requirements for explosion protection while concentration differences can still be measured via sensitive detection.
