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.

‘The Plastic Nile’: First Evidence of Microplastic Contamination in Fish from the Nile River (Cairo, Egypt)

open access: yesToxics, 2020
The presence of microplastics (MPs) in the world’s longest river, the Nile River, has yet to be reported. This small-scale study aimed to provide the first information about MPs in the Nile River by sampling the digestive tracts of two fish species,

Excited State Modulation in Carbene‐Metal‐Amides to Design Fast and Bright Blue Delayed Fluorescence

open access: yesAdvanced Functional Materials, EarlyView.
Gold‐centered carbene‐metal amide (CMA) materials with carbonyl‐group substitution on the amide donor ligand. Molecular design ensures that the charge transfer (CT) state is lower in energy than the locally excited (3LE) states. The energy difference between CT and LE states controls the rate of the delayed fluorescence.

Double Helical Plasmonic Antennas

open access: yesAdvanced Functional Materials, EarlyView.
Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.

Additively Manufactured Diamond for Energy Scavenging and Wireless Power Transfer in Implantable Devices

open access: yesAdvanced Functional Materials, EarlyView.
Additive manufacturing is expanding beyond mechanical prosthetics into microelectronic implants. This work presents a diamond‐titanium hybrid that enables wireless power transfer, localized heating, and flow sensing. The use of additive manufacturing combined with the biocompatibility of the diamond‐titanium hybrid material paves the way toward new ...

Functionalized Lignin Derivatives as Melt‐Spinnable Precursors for Carbon Fiber Production without Stabilization

open access: yesAdvanced Functional Materials, EarlyView.
By turning off hydrogen bonds by bulky ethyl cinnamate ester derivatization, softwood kraft lignin can flow under elevated temperatures, providing tough fiber in the melt for high take‐up speed. Subsequently, lignin ethyl cinnamate derivatives are readily stabilized with only dilute nitric acid leading to direct carbonized fiber with outstanding ...

A Case of a 34-Year-Old Female with Acute Hypoxemic Respiratory Failure and Proximal Muscle Weakness

open access: yesCase Reports in Critical Care, 2017
Wound associated botulism is an unusual presentation. Early detection of this potentially life-threatening illness can significantly shorten length of hospital stay and improve prognosis. We present a case of a 34-year-old female with a history of heroin
