Challenges and enablers in fluidization technology

AIChE Journal, EarlyView.
Abstract Gas–solid fluidized beds provide excellent heat and mass transfer for high‐throughput operations from coating to catalytic conversion and underpin emerging low‐carbon technologies. Yet industrial reliability, scale‐up, and control lag scientific understanding, particularly as finer, stickier, and more variable feedstocks increasingly challenge

The Redshift Distribution of Type-Ia Supernovae: Constraints on Progenitors and Cosmic Star Formation History [PDF]

, 2003
We use the redshift distribution of type-Ia supernovae (SNe) discovered by the Supernova Cosmology Project to constrain the star formation history (SFH) of the Universe and SN Ia progenitor models.

Bayesian Optimization Guiding the Experimental Mapping of the Pareto Front of Mechanical and Flame‐Retardant Properties in Polyamide Nanocomposites

Advanced Intelligent Discovery, EarlyView.
Bayesian optimization enabled the design of PA56 system with just 8 wt% additives, achieving limiting oxygen index 30.5%, tensile strength 80.9 MPa, and UL‐94 V‐0 rating. Without prior knowledge, the algorithm uncovered synergistic effects between aluminum diethyl‐phosphinate and nanoclay.

The Grey Zone of Stakeholder Engagement: Misalignment as a Manifestation of Greyness in Stakeholder Collaboration

Business Strategy and the Environment, EarlyView.
ABSTRACT This study identifies and conceptualises the grey zone of stakeholder engagement and explores how it manifests in a collaborative context related to the promotion of a circular economy. While prior research on stakeholder engagement has highlighted the positive, value‐creating bright side or the harmful dark side of stakeholder engagement, we ...
