Waste Polystyrene Chain Scission With Ball Milling: Mass‐Dependent Kinetics and Energy‐Dose Analysis

open access: yesJournal of Polymer Science, EarlyView.
Ball‐milling‐induced chain scission of real‐world polystyrene samples exhibits a systematic dependence on polymer mass when particle size is controlled. Scission rate constants follow power‐law scaling, and molecular weight evolution data collapse when analyzed by mechanical energy dose.

Digitizing collections to unlock the full potential of palynology: A case study with the Smithsonian palynology collection

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Large palynological collections have been built over decades and contain vital information. However, they are often difficult to access and use effectively. What is the point of having such collections if they are not fully utilizable? To solve this problem, we digitized the Smithsonian palynological collection using both light and confocal microscopy.

Road air pollution harms the reproductive success of a bee‐pollinated wildflower: A dusty threat to biodiversity

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Dust, a common form of air pollution, is particularly problematic on roadsides, which are important habitats for plants and pollinators. We investigated whether and how road dust affects plant sexual reproduction using Primula chungensis in a biodiversity hotspot. Our study provides compelling evidence that road dust can harm plant reproductive success

Intrinsic and Water‐Triggered Hydrophilicity in Tween 20‐PDMS Composites for Dynamic and Long‐Term Wettability Control

open access: yesSmall, EarlyView.
A one‐step bulk integration of the surfactant Tween 20 into PDMS enables intrinsic and water‐triggered hydrophilicity. Combined molecular simulations and experiments reveal a dual mechanism where bound and mobile Tween 20 molecules cooperatively induce self‐activating, stretch‐tolerant, and long‐term wettability, supporting self‐driven liquid transport,
