Le potentiel réflexif de la modélisation des environnements personnels d’apprentissage

open access: yesDistances et Médiations des Savoirs, 2019
Based on a language for modelling personal learning environments (PLE) of higher education students that we have developed (Felder, sous presse), this explorative research aims to evaluate the potential of PLE models of students generated by the ...

O Uso de Operadores Argumentativos em Notícias Online

open access: yesDomínios de Lingu@gem, 2012
A velocidade da internet se consolidou também no jornalismo online, o que fez com que esse novo espaço interferisse nos processo de produção do jornalismo contemporâneo que teve que se adequar a esse novo (ciber)espaço.

Spatial–Temporal Evolution and Coupling and Coordination of “Production–Life–Ecological” in Energy-Rich Area: A Perspective on Structure and Function

open access: yesLand
The conflict between socio-economic development and ecological protection is prominent, as the practice framework for territorial spatial planning and the rational layout and function coordination of production–life–ecological (PLE) spaces are crucial ...

Ambient‐Light‐Activated Rewritable Optical Patterning in Transparent Long‐Afterglow Garnet Ceramics

open access: yesLaser &Photonics Reviews, EarlyView.
This work demonstrates sunlight‐activated rewritable optical information storage in transparent long‐afterglow Y3Al2Ga3O12:Ce (YAGG:Ce) garnet ceramics fabricated via solid‐state sintering with tetraethyl orthosilicate (TEOS) as a sintering aid. By integrating ambient‐light operability, reversibility, and high optical clarity in a robust ceramic host ...

Synergistic Multi‐Strategy Engineering of Temperature‐Responsive Self‐Trapped Excitons in Tin‐Based Double Perovskite Nanocrystals Enables High‐Sensitivity Fluorescence Thermometry

open access: yesLaser &Photonics Reviews, EarlyView.
Bi3+‐doped Cs2SnCl6 nanocrystals are engineered to deliver highly temperature‐responsive self‐trapped exciton emission, achieving record thermal sensitivity at elevated temperatures. A temperature‐induced dual‐STE excited state landscape enables reversible thermochromism, while a dual‐parameter calibration combining fluorescence lifetime and CIE‐y ...

Predicting Statistical Signatures of Collective Emission in Disordered Color Center Ensembles

open access: yesLaser &Photonics Reviews, EarlyView.
We present an efficient simulation framework for modeling collective emission in disordered ensembles of quantum emitters. The low computational complexity enables large‐scale Monte Carlo simulations. Applied to SiV−${\rm SiV}^{-}$ clusters, it predicts thresholded superradiant bursts set by emitter number and quantum efficiency, as well as interaction‐

Zero‐Dimensional Perovskite‐Inspired Scintillator‐Based High‐Radiation‐Resistant Radionuclide Analyzer Free From Irreversible Degradation

open access: yesLaser &Photonics Reviews, EarlyView.
A zero‐dimensional perovskite‐inspired scintillator (Cs3Cu2I5) is developed as a high‐radiation‐resilient radionuclide analyzer capable of operating under extreme γ‐ray environments. Even after 200 kGy irradiation, the device fully restores its original spectroscopic performance through simple thermal annealing, demonstrating intrinsic defect ...

Market Interviews in Shared Traumatic Reality: A Trauma‐Informed, Co‐Constructed Framework

open access: yesPsychology &Marketing, EarlyView.
ABSTRACT Qualitative market interviews may become trauma‐sensitive when ordinary questions about consumption, work, finance, mobility, identity, professional continuity, or institutional trust intersect with displacement, insecurity, loss, or ongoing threat.

Design and optoelectronic profiling of a semicrystalline thiophene–phenylene copolymer for advanced organic electronics

open access: yesPolymer International, EarlyView.
A new semicrystalline copolymer, PTBT‐3OBu, was synthesized. Intramolecular S···O conformational locks induce high backbone planarity, promoting strong interchain coupling and molecular ordering in thin films, seen in an optical red shift. This synergy between planarity and semicrystalline morphology is promising for photovoltaic and electrochromic ...
