Machine learning‐driven advances in carbon‐based quantum dots: Opportunities accompanied by challenges

open access: yesResponsive Materials, EarlyView.
Machine learning provides a unifying framework to connect structure, fluorescence properties, and applications of carbon‐based quantum dots. This review highlights how data‐driven strategies enable fluorescence regulation, reveal underlying mechanisms, and accelerate the rational design of functional carbon dots.

Engineering Cobalt‐Based Thin Films for Fischer–Tropsch Synthesis

open access: yesSmall, EarlyView.
Cobalt thin films with tailored crystalline phases and oxidation states serve as well‐defined model Fischer–Tropsch catalysts. In situ synchrotron GIXRD reveals distinct reduction behaviour and phase evolution, while catalytic testing demonstrates phase‐dependent hydrocarbon selectivity and improved structural stability. These model thin‐film catalysts

Revealing Airflow–Particle Dynamics in Dry Powder Inhalers

open access: yesSmall, EarlyView.
An integrated framework combining device and formulation characterization, CFD–DEM simulations, and interpretable machine learning is established. This framework reveals how airflow and particle interactions govern powder dispersion across prevailing dry powder inhalers.

Rhodium Cluster Catalysts Enable Efficient Catalytic Hydroformylation in Mild Conditions: Cluster Size Dependence

open access: yesSmall, EarlyView.
Nanometer‐sized Rh clusters provide a specific reaction environment that facilitates the balanced co‐adsorption of styrene, CO, and H, thereby promoting hydroformylation. ABSTRACT The size of the reactive metal domain, termed an ‘ensemble’, in supported metal catalysts critically influences their catalytic activity.

Facilitated Zn2+ Transport and Preferential Zn (100) Deposition Enabled by Amorphous ZrOx‐C Hybrid Thin Film for High‐Performance Aqueous Zinc‐Ion Batteries

open access: yesSmall, EarlyView.
An amorphous ZrOx with carbon (a‐ZrOx‐C) hybrid interphase is engineered to overcome interface instability in aqueous zinc‐ion batteries. By boosting Zn2+ transport kinetics, this unique gradient architecture promotes preferential Zn(100) deposition, effectively suppressing dendrites and side reactions.
