Ferroelectric Quantum Dots for Retinomorphic In‐Sensor Computing

open access: yesAdvanced Materials, EarlyView.
This work has provided a protocol for fabricating retinomorphic phototransistors by integrating ferroelectric ligands with quantum dots. The resulting device combines ferroelectricity, optical responsiveness, and low‐power operation to enable adaptive signal amplification and high recognition accuracy under low‐light conditions, while supporting ...

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

open access: yesAdvanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Voyager, voir et faire voyager

open access: yesCalenda, 2009
Le colloque du projet VIATICALPES se propose un triple objectif : explorer les questions scientifiques et esthétiques posées par la représentation des choses vues dans les voyages ; interroger les rapports entre texte et image dans les récits de voyage ; et discuter les avantages et les difficultés que présente l’exploitation d’une base de données dans

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

open access: yesAdvanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Did Vasco da Gama Matter for European Markets? Testing Frederick Lane's Hypotheses Fifty Years Later [PDF]

open access: yes
In his seminal publications between the 1930s and 1960s, Frederick Lane offered three hypotheses regarding the impact of the Voyages of Discovery that have guided debate ever since. First, pepper and other spice prices did not rise in European markets in
