From Bench to Bulk: Investigating Kinetics, Recyclability, and Scale‐Up of ZIF‐67

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 3, May/June 2026.
ABSTRACT Zeolitic imidazolate framework‐67 (ZIF‐67), a subclass of metal–organic frameworks (MOFs), has garnered considerable attention due to its high surface area, open crystal structure, tunable porosity, and potential applications in gas separation, catalysis, and carbon capture.

Influence of Zn2+ and Oxygen Supply on Malic Acid Production and Growth of Aspergillus oryzae

Biotechnology and Bioengineering, Volume 123, Issue 5, Page 1123-1138, May 2026.
ABSTRACT Malic acid is a valuable platform chemical traditionally derived from fossil‐based resources. Microbial cultivation with Aspergillus oryzae offers a sustainable alternative based on renewable feedstocks. In this study, a well‐established minimal medium for malic acid production, commonly used in previous research to ensure reproducibility, was

Comparison of saw tooth impeller and Rushton turbine

AIP Conference Proceedings, 2019
On the basis of numerical simulations, the comparisons of turbulent characteristics in mixing tanks equipped with a saw-tooth impeller and a Rushton turbine are shown in this contribution. Numerical simulations were performed using the LES model, which is implemented in the OpenFoam environment.On the basis of numerical simulations, the comparisons of ...

Mistuned Vibration of Radial Inflow Turbine Impeller

Journal of Fluid Science and Technology, 2008
This paper is concerned with the numerical prediction of impeller blade vibration due to excitation by the wake of nozzle guide vanes in turbochargers. This problem is particularly important as turbochargers are used in a broad range of operation conditions, leading to some unavoidable resonant frequencies.

Gas-Liquid Agitation with Closed Turbine Type Impellers Modified for Blade Geometries [PDF]

Chemical and Biochemical Engineering Quarterly
An agitation impeller with shrouded blades—specifically, a closed impeller—was redesigned. A closed impeller originating from a conventional turbine-type impeller was analyzed by considering the internal liquid flow characteristics.
