Dynamics of droplet breakup symmetrically placed between two collapsing cavities via numerical simulations

open access: yesUltrasonics Sonochemistry
Hydrodynamic cavitation is increasingly used for the production of liquid–liquid emulsions, yet the detailed mechanisms of droplet breakup induced by cavity collapse remain poorly understood.

Dual Single Atoms Boosting Photocatalytic Upcycling of Raw Polyvinylidene Fluoride Plastic

open access: yesAdvanced Materials, EarlyView.
To resolve the catastrophic disaster of plastic contamination, the Cu‐Fe dual‐single‐atom‐loaded In2P3S9 NSs photocatalyst was prepared for direct conversion of raw polyvinylidene fluoride plastic into valuable chemicals. The dual‐single‐atom catalyst exhibits exceptional performance, with a total acetic/formic acid production of ∼1351.8 µmol g−1 ...

Wafer‐Scale Direct Growth of Ultraclean Monolayer Amorphous Carbon on c‐Sapphire by Remote Catalytic Dehydrogenation

open access: yesAdvanced Materials, EarlyView.
Remote catalytic dehydrogenation enables the direct growth of monolayer amorphous carbon on a 2‐inch sapphire wafer by thermal CVD. Spatial separation of the catalyst from the growth substrate eliminates metallic residue and post‐growth processing, yielding a wafer‐scale uniform film with a random polygonal sp2‐hybridized carbon network that exhibits ...

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

open access: yesAdvanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Culinary Chemistry as a Platform for Interfacial Materials Design

open access: yesAdvanced Materials Interfaces, EarlyView.
Culinary processes control interfaces through heating, shear, gelation, and molecular transport. This Review connects selected gastronomic examples with food‐derived nanomaterials, plasmonic sensing, anthocyanin photovoltaics, and intelligent packaging. Original agar‐based plasmonic films illustrate the proposed translation.
