From Single Atoms to Nanoparticles: Pathways Toward Efficient and Durable Pt/TiO2 Photocatalysts

Advanced Functional Materials, EarlyView.
Platinum single atoms on TiO2 nanosheets evolve into clusters and nanoparticles under ethanol photoreforming and thermal treatments. By controlling deposition and post‐treatments, particle size and location on specific facets are modulated. The study reveals how stability pathways determine efficiency, guiding the design of more durable photocatalysts.

Single‐ and Dual‐Atom Configurations in Atomically Dispersed Catalysts for Lithium–Sulfur Batteries

Advanced Functional Materials, EarlyView.
Single‐atom and dual‐atom‐based atomically dispersed catalysts (ADCs) effectively address the shuttle effect and sluggish redox kinetics in Li–S batteries. With nearly 100% atomic utilization and tunable coordination environments, ADCs enhance LiPSs adsorption, lower conversion barriers, and accelerate sulfur redox reactions.

The architecture of predator-prey and the relationship between complexity and stability [PDF]

, 2010
Theoretical studies predict that the stability of an ecosystem is negatively correlated with its complexity, measured by the number of interacting species. On the other hand, empirical evidence indicates that food webs are highly interconnected.

Navigating novel resources: A field test of the effects of small mammal personality on dispersal of Quercus seeds

Ecosphere
Climate change is shifting the habitable ranges of hundreds of species, and a greater understanding of the mechanisms driving migration velocity may make the difference between extinction and persistence for at‐risk species. However, predicting migration

Continued Deforestation Could Wipe out Key Ecological Functions of Parrots Before They Are Documented in Madagascar

Conservation
Madagascar is a global biodiversity hotspot, with approximately 90% of all its plant and animal species being endemic, most of them associated with forest ecosystems. This rich biodiversity is threatened by relentless deforestation; in 2014 only about 15%

Coating Artificial Spider Silk Fiber with Magnetic FeCo: An Effective Strategy for Creating a Flexible Magneto‐Responsive Material

Advanced Functional Materials, EarlyView.
An original method is presented for producing artificial spider silk fibers with magnetic and magnetomechanical responsiveness, which consists in coating them with a nanometer‐thick layer of FeCo alloy by sputtering deposition. The challenge of combining organic materials and inorganic magnetic nanostructures is addressed, thus taking a step forward ...
