Les plans de pistes de ski : une saison hivernale fantasmée

open access: yesEchoGéo
Since the creation of ski resorts, there has been a proliferation of piste maps for skiers. By analysing several French maps and a few foreign ones, we will look at the representations of the mountains, via the ski areas, that these maps convey.

A Shadow on the Sky [PDF]

open access: yesNature, 1871
ON the 21st of last August, being at Zermatt, Switzerland, I witnessed from the balcony of the salle-a-manger of the Hotel du Mont Cervin a very remarkable appearance. The sun had recently set, and, as I was intensely enjoying the view of that extraordinary mountain, the Matterhorn, I saw its shadow thrown upon the clear sky in the most distinct manner.

High‐Performance Low‐Emissivity Paints Enabled by N‐Doped Poly(benzodifurandione) (n‐PBDF) for Energy‐Efficient Buildings

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a scalable and colored low‐emissivity (low‐e) paint achieved by spraying an ultrathin n‐doped poly(benzodifurandione) (n‐PBDF) coating onto various colored substrates. The low‐e paint enhances thermal regulation by reducing mid‐infrared thermal emissivity to 0.19, thereby stabilizing indoor temperatures across diverse climates ...

Enhanced Terahertz Spectroscopy of a Monolayer Transition Metal Dichalcogenide

open access: yesAdvanced Functional Materials, EarlyView.
An ad‐hoc engineered metallic surface is employed to perform enhanced terahertz spectroscopy of a monolayer transition metal dichalcogenide (TMD). Thanks to a local absorption boost of 104, this technique allows for the extraction of the phonon resonance features and effective permittivity of the 2D material, paving the way for the rational design of ...
