Adsorption‐Engineered Hydrocarbon Ionomers for Durable Proton‐Exchange Membrane Fuel Cells

Advanced Materials, EarlyView.
Hydrocarbon ionomers suffer from oxidation‐driven interfacial degradation in PEM fuel cell cathodes, leading to catalyst instability. Here, adsorption‐engineered poly(fluorene) ionomers decouple interfacial anchoring from oxidative degradation, enabling strong catalyst–ionomer interactions while resisting electrochemical oxidation.

Use of a towed camera system to investigate benthic habitat use by inter-nesting female hawksbill sea turtles

Endangered Species Research, 2014
The types of marine benthic habitats utilised by hawksbill sea turtles Eretmochelys imbricata nesting at Needham’s Point, Barbados, were investigated using an underwater drop camera. Habitats used preferentially (i.e.

Interfacial Failure and Self‐Healing in Solid‐State Batteries

Advanced Materials, EarlyView.
Dynamic interfacial self‐healing offers an adaptive route to mitigate coupled mechanical, chemical, and electrochemical degradation in solid‐state batteries. This review connects evolving interfacial failure mechanisms with physical‐flow, chemical‐restoration, stimuli‐responsive, and electric‐field‐assisted repair strategies, highlighting targeted self‐

Biology and ecology of the El Convento Cave-Spring System (Puerto Rico)

International Journal of Speleology, 1974
The El Convento Cave-Spring System is located at the head of the Quebrada de Los Cedros, approximately 20 km. west of Ponce, southwestern Puerto Rico. Although situated in an arid environment, the gorge receives sufficient moisture from the cave-spring system to support an abundant flora, with Bucida buceras and Bursera simaruba as the dominant trees ...

Negotiating in a Foreign Land: Understanding the Curious Interactions Between Intracellular Mitochondria and Internalized Nanoparticles

Advanced Materials Interfaces, EarlyView.
Therapeutic nano‐drug delivery systems interact with cellular mitochondria in a multitude of ways. While the complexity of such interactions disrupts the mitochondrial electron transport chain and increases reactive oxygen species production, thereby contributing to nanoparticle toxicity, they also present unique theranostic opportunities in diseases ...

Micropillar‐Engineered Hybrid Adhesive Patch for Surface‐Conformable and Directional Adhesion

Advanced Materials Technologies, EarlyView.
This work presents a surface‐conformable hybrid adhesive integrating height‐optimized hexagonal micropillars with open‐rectangular cuts. The micropillars enhance rough‐surface contact and microscale crack arrest, while the cuts guide and reverse interfacial cracks for strong and directional adhesion. The multiscale architecture achieves robust pull‐off

Some paleontological evidence of cave lion biology

Slovenský Kras, 2018
A skull of cave lion, Panthera spelaea (Goldfuss, 1810) was discovered in glacialdeposits in north-eastern Russia. It reveals deep traces of canine teeth on its face, associated with suffocation by another lion. This was the real cause of death and one of the manners of modern lions killing.
