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

open access: yesAdvanced 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.

Porous Coatings by Vapor Sublimation and Deposition for Molecular Channeling and Filtration in an Interstitial Fluid Microfiltration Device

open access: yesAdvanced Healthcare Materials, EarlyView.
A vapor‐based porous coating applied within nitinol tubes demonstrated complete suppression of cellular and tissue ingrowth, overcoming a major limitation of implantable interstitial fluid collection devices. Molecular channeling and diffusion are analyzed with probe molecules, showing reliable transport in vitro and in vivo. The coating also achieved >

Giant Berry‐phase‐Driven X‐Ray Beam Translations in Strain‐Engineered Semiconductor Crystals

open access: yesAdvanced Materials, EarlyView.
Due to the Berry‐phase effect, X‐rays propagating in deformed crystals undergo large translations, interesting for X‐ray optics applications. Here, the lattice expansion observed upon H irradiation of dilute‐nitride semiconductors is exploited to engineer the deformation landscape of selectively hydrogenated GaAsN epilayers.

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

open access: yesHesperis-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

Romans, Roads, and Romantic Creators: Traditions of Public Property in the Information Age [PDF]

open access: yes, 2003
The medialibrary is included within an overall development plan. This plan has been drawn up by the communal office and aims to finish in 2030. The aim of this design is to promote unification and comunication, especially in the central area of ...

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

open access: yesAdvanced 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

All the Roads to Patavium: Morphology, Genesis and Development of the Roman Road Network Around Padua

open access: yesOpen Archaeology, 2017
This paper deals with the analysis of the ancient road network around the city of Padua, attempts to reconstruct its morphology and to define its genesis and development between the second Iron Age and Late Antiquity (6th/5th cent. BC to 6th cent.

Notes About Crushing Sand from Bituminous Schist

open access: yesBulletin of the Polytechnic Institute of Jassy: Constructions, Architechture Section, 2021
People have used sand and stone for foundations for thousands of years. Significant refinement of the production and use of aggregate occurred during the Roman Empire, which used aggregate to build its vast network of roads and aqueducts.

Climate Change Agricultural Comparative Advantage and the US Trade Balance

open access: yesApplied 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.
