Emerging Technologies for Biobutanol Production via Syngas Fermentation
Biobutanol production from syngas is promising but limited by microbial energy conservation and gas–liquid mass transfer. This review integrates advances in cultivation control and bioreactor engineering with next‐generation biological tools including metabolic rewiring, co‐cultivation and chain elongation, and electro‐fermentation to enable carbon ...

Grinding chips of high‐alloyed steel are prepared to be admixed to a starting powder mixture for laser powder bed fusion. A three‐stage preparation is performed, including washing in acetone, magnetic separation, and ball milling. The addition of 30% of grinding chips to the powder mixture allows the fabrication of dense samples.

ABSTRACT The steel industry is among one of the largest CO2 emitters in the world. To meet climate targets, replacing fossil‐based carbon with renewable biocarbon in metallurgical processes, particularly in blast furnaces (BFs) and electric arc furnaces (EAFs), has emerged as a viable short‐ to mid‐term solution.
