Liquid Crystal Elastomers Under Confinement: A Review of Template‐Based Fabrication and Applications

open access: yesAdvanced Engineering Materials, EarlyView.
Template‐assisted confinement offers powerful ways to control the alignment, structure, and function of liquid crystal elastomers. This review highlights several templating strategies and details how geometry and interfaces shape material responses.

Un outil de la paix ?

open access: yesRevue d’Histoire des Sciences Humaines, 2018
Born in the mid-19th century, aerial photography that has no evident use, can not be touted as a great success before the 1910s. During World War One, however, it is mobilized by the belligerants, as it can be used to map in short time, to unveil the ...

La méthode de la photo-interview à partir de la photographie aérienne

open access: yesEchoGéo, 2020
Aerial photography presents almost exhaustively the morphology and land use of the photographed space, but does not represent the social dimension of the studied territory.

3-Dimensional Building Details from Aerial Photography for Internet Maps

open access: yesRemote Sensing, 2011
This paper introduces the automated characterization of real estate (real property) for Internet mapping. It proposes a processing framework to achieve this task from vertical aerial photography and associated property information. A demonstration of the

Tracking Fine-Scale Structural Changes in Coastal Dune Morphology Using Kite Aerial Photography and Uncertainty-Assessed Structure-from-Motion Photogrammetry

open access: yesRemote Sensing, 2018
Coastal dunes are globally-distributed dynamic ecosystems that occur at the land-sea interface. They are sensitive to disturbance both from natural forces and anthropogenic stressors, and therefore require regular monitoring to track changes in their ...

Fabrication of Multifunctional FeSi Gyroid Lattice Composites via Additive Manufacturing and Polymer Infiltration

open access: yesAdvanced Engineering Materials, EarlyView.
A two‐step approach combining laser powder bed fusion of FeSi electrical steel with Bakelite infiltration enables the fabrication of multifunctional gyroid lattice composites. The resulting structures exhibit high strength, magnetic anisotropy, and complete polymer infiltration, demonstrating a simple and scalable route toward lightweight, mechanically

Efficient and Scalable Radiative Cooling for Photovoltaics Using Solution‐Processable and Solar‐Transparent Mesoporous Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
Graded refractive index (GRI) structures are prepared from the layer‐by‐layer spray coating of the mesoporous SiO2 nanoparticles, showing high solar transparency and thermal emissivity. Under outdoor conditions, after 50 days, the GRI‐coated photovoltaics show on average 6.65 ± 1.48 °C lower than that of the non‐coated references, maintaining 80.9 ± 8 ...
