Scalable catalyst production process for oleate hydratase whole‐cell biocatalysis
Biotechnology Progress, EarlyView.This study establishes a scalable lactose‐induced fed‐batch fermentation for an Escherichia coli whole‐cell biocatalyst containing an oleate hydratase. Operation at a higher growth rate markedly increased biomass yields while maintaining catalyst activity and was demonstrated at 150 L scale.

Prospective LCA of E‐Methanol Along the Transformation of Steel Industry
Chemie Ingenieur Technik, EarlyView.The environmental effects of change in steel production route on e‐methanol production are analyzed as they shift from blast furnace route to direct reduction route. Specific hydrogen demand reduces, as do the avoided CO2 emissions. E‐methanol's overall carbon footprint stays in a narrow range of −1 to −1.1 kg‐CO2‐eq./kg‐methanol.

Laminar Burning Velocity of Ammonia‐Hydrogen Mixtures Predicted by Machine Learning
Chemie Ingenieur Technik, EarlyView.Ammonia–hydrogen blends aid defossilization, but slow combustion kinetics require complex modeling. Although chemical kinetic modeling is computationally expensive, machine learning surrogates offer fast predictions. This study trained GPR, DT, and ANN models on 1445 experimental points.

Transpiration cooling for double-walled jet engine turbine blades [PDF]
Increasing thermal loads on turbine blades has led to the need for more advanced cooling sys- tems. Transpiration cooling techniques are of renewed interest, partly because of more ad- vanced manufacturing methods, and are characterised by small film ...
