Simulating communication routes in Mediterranean alluvial plains [PDF]

, 2008
Societies exchange knowledge, ideas and merchandise throughout their territories. Topography plays a fundamental role in the trajectory of such movements whilst helping to explain the distribution of human constructions.

Suburbanization and highways: when the Romans, the Bourbons and the first cars still shape Spanish cities [PDF]

, 2013
We estimate the effects of highways on the suburbanization of Spanish cities. First, we extend previous findings for the US and China by providing evidence for Europe: each additional highway ray built between 1991 and 2006 produced a 5 per cent decline ...

Inactivating SARS‐CoV‐2 Virus with MOF‐Composites as Smart Face Masks

Advanced Functional Materials, EarlyView.
In situ preparation and functionalization of MOF@Cotton fabrics as smart face masks for the immobilization of proteins and inactivation viruses, such as SARS‐CoV‐2. Abstract The significant impact of the SARS‐CoV‐2 (COVID‐19) pandemic outbreak on people's lives has highlighted the urgent need for effective personal protective equipment.

Scalable Thermal Engineering via Femtosecond Laser‐Direct‐Written Phononic Nanostructures

Advanced Functional Materials, EarlyView.
This study demonstrates that femtosecond laser‐induced periodic surface structures (fs‐LIPSS) can function as phononic metasurfaces, reducing thermal conductivity below the plain thin‐film limit. Phonon Monte Carlo analysis reveals that the periodic structures restrict phonon mean free paths.

Laser‐Synthesized Amorphous PdSe2‐x Nanoparticles: A Defect‐Rich Platform for High‐Efficiency SERS, Photocatalysis, and Photothermal Conversion

Advanced Materials Interfaces, EarlyView.
Using femtosecond ablation, we show that an ordered, stoichiometric crystalline PdSe2 target can be controllably converted into a stable, disordered, non‐stoichiometric, and highly functional amorphous nanomaterial, PdSe2−x${\rm PdSe}_{2-x}$. The obtained nanoparticles offer significant advantages over conventional planar plasmon‐free substrates due to

In Situ Elucidations of the Mechanism for Inert Molecular N2O Decomposition at Low Temperature Catalyzed by High‐Index Interfacial Exposed Co3O4

Advanced Science, EarlyView.
This study develops a co‐precipitation followed by hydrothermal synthesis strategy for synthesizing Co3O4 catalyst with multiple high‐index facets. Experiments and density functional theory calculations demonstrate that Co3+ on the (400–400) facet can form a novel active Co3+‐O* motif during the reaction.

Climate Change Agricultural Comparative Advantage and the US Trade Balance

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Current science indicates that warming and elevated atmospheric CO2 will have ambiguous results for crop productivity depending on crop type and geographic location, whereas increased heat stress makes livestock and human labor less productive.

Ancient Itineraries and Paths in Morocco: Tracks Lines and Material Realities [PDF]

Hesperis-Tamuda, 2023
Two main north-south land routes, which ran from Tangier to Sala/Rabat on the coast on the one hand, and Volubilis in the interior on the other, are attested in Tingitane by the Antonine Itinerary, which provides a list of stations for the Roman province
