Differentiated financing of schools in French-speaking Belgium: prospectives for regulating a school quasi-market [PDF]

open access: yes
The school quasi-market in French-speaking Belgium is characterised by segregation of various types. Efforts to apply measures that encourage greater social mixing have met with stiff resistance and various difficulties.

High Entropy Wide‐Bandgap Borates with Broadband Luminescence and Large Nonlinear Optical properties

open access: yesAdvanced Functional Materials, EarlyView.
High‐entropy rare‐earth borates exhibit excellent nonlinear optical and broadband luminescence properties arising from multi‐component doping, chemical disorder, increased configurational entropy, and increased lattice and electronic anharmonicity. This formulation enabled us to obtain a large, environmentally stable single crystal with 3X higher laser‐

Métropoles en mouvement : une comparaison internationale [PDF]

open access: yes, 2000
Cet ouvrage collectif est le fruit des contributions et des débats qui ont eu lieu lors de l'Atelier International « Métropoles en Mouvement. Les interactions entre formes de mobilité et recompositions territoriales à l'épreuve de la comparaison ...

Copper‐Based Crystalline‐Metallic Glass Composite Thin Films: A Novel Material with Enhanced Strength and Thermally Stable Nanotwins

open access: yesAdvanced Functional Materials, EarlyView.
A Cu‐based crystal‐glass composite with high‐density twins is identified by a fast screening technique using combinatorial sputtering together with XRD and nanoindentation mapping. This bamboo‐like structure demonstrates homogenous plastic flow and retains high strength during in situ high temperature tests, up to 1 GPa at 550°C, owing to those ...

La ségrégation spatiale selon Schelling : la perversité est ailleurs [PDF]

open access: yes
In the 1970s, Thomas C. Schelling proposed a model which claimed to show that a high degree of spatial segregation can result from individual preferences which do not in themselves aim to achieve such a degree of collective segregation. A perverse effect

Bio‐Inspired Molecular Events in Poly(Ionic Liquids)

open access: yesAdvanced Functional Materials, EarlyView.
Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...

Urban segregation and labour markets within the Bordeaux metropolitan area: an investigation of the spatial friction [PDF]

open access: yes
This article aims at providing a test of the spatial mismatch hypothesis on the Bordeaux metropolitan area. Starting with a theoretical survey of the complex links between residential segregation and local labour markets, we then propose a framework ...

Harnessing the Orientation of Columnar Discotic Liquid Crystals for Narrowband Blue Emission with Enhanced Out‐Coupling Efficiency Toward Improvement of SP‐OLEDs Performance

open access: yesAdvanced Functional Materials, EarlyView.
Solution‐processed OLEDs containing discotic liquid‐crystalline MR‐TADF emitters are reported. Supramolecular self‐assembly induces homeotropic columnar alignment, enforcing preferential horizontal orientation of the emitter transition dipole moment in spin‐coated films, which leads to an enhancement in the device light outcoupling efficiency while ...
