From Bench to Bulk: Investigating Kinetics, Recyclability, and Scale‐Up of ZIF‐67
Asia-Pacific Journal of Chemical Engineering, EarlyView.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, EarlyView.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

Business Strategy and the Environment, EarlyView.ABSTRACT The role of business towards achieving the 17 Sustainable Development Goals (SDGs) has been well established. However, SDG contextualization continues to pose a conundrum, particularly for firms operating in multiple contexts. This becomes even more problematic in the case of SDG 11, the only goal in the sustainable development agenda directly

Business Strategy and the Environment, EarlyView.ABSTRACT The present study applied the diffusion of innovation theory to investigate the rate of diffusion of renewable energy sources used by Europe's top professional football stadiums and the relationship with carbon neutrality. A discrete diffusion model estimated the diffusion of renewable energy to saturation, and a multivariate logistic ...

Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT We describe the “skipping rope technique” for managing burr entrapment during rotational atherectomy. Sequential counterclockwise rotational force is applied to the drive shaft, generating alternative torque dynamics. This maneuver provides a safe method to disengage a stuck rotaburr, offering operators an additional strategy for this ...

Automated Process Optimization in a Novel Triple Shaft Mixer with Adaptive Mixing Modes
Chemie Ingenieur Technik, EarlyView.A novel multi‐purpose mixer with adjustable blade angle and a coaxial stirrer is developed, providing three degrees of freedom. An optimization strategy is integrated to autonomously identify optimal operating conditions through automated tests. The current draw of the main stirrer serves as the optimization criterion, while stirrer speeds, directions,
