Test Scores, Subjective Assessment and Stereotyping of Ethnic Minorities [PDF]

open access: yes
We assess whether ethnic minority pupils are subject to low teacher expectations. We exploit the English testing system of “quasi-blind” externally marked tests and “non-blind” internal assessment to compare differences in these assessment methods ...

Shape‐Changing Multiphase Microparticles from Complex Liquid Crystal Emulsions

open access: yesAdvanced Functional Materials, EarlyView.
Liquid crystalline network (LCN) microparticles are prepared from single, double (Janus), and triple emulsions through a simple and scalable bulk‐emulsification strategy. Under heating, the particles exhibit robust, reversible, large‐amplitude deformations that depend both on the morphology and the liquid crystals director field configuration.

Built‐In Interfacial Electric Field in Hydroxyl‐Terminated MXene/COF Heterostructures for Enhanced Solid‐State Supercapacitors

open access: yesAdvanced Functional Materials, EarlyView.
Hydroxyl‐terminated MXene is integrated with a redox‐active covalent organic framework through electrostatic self‐assembly followed by hydrothermal treatment to construct MXene/COF heterostructures with a built‐in interfacial electric field. Termination‐controlled interfacial electronic modulation induces charge redistribution and favorable band ...

Graphene Nanosheet‐Based Mixed Proton‐Electron Conducting Membranes for Efficient Hydrogen Purification

open access: yesAdvanced Functional Materials, EarlyView.
A monolayer graphene/phosphoric‐acid mixed proton‐electron conducting membrane combines proton‐conducting nanoconfined acid channels with electron‐conducting graphene nanosheets for efficient high‐temperature hydrogen purification. The membrane achieves nearly 100% H2/CO2 selectivity and 69 GPU hydrogen permeance at 250°C, arising from synergistic ...

Record Energy Storage Performance Metrics in Ferroelectric Hafnia‐Based Films through Heterostructure Design

open access: yesAdvanced Functional Materials, EarlyView.
Dielectric capacitors typically struggle to achieve both high energy storage density and high efficiency at applied voltages below 10 V. Here, we address this challenge by introducing a novel hybrid fluorite/perovskite heterostructure design that combines ultra‐high recoverable energy storage density with efficient energy release (Uf ≈ 1016 J/cm3), at ...

Evidence of Returns to Education Among Roma in Central and Eastern Europe and Their Policy Implications [PDF]

open access: yes
In this paper we analyze specific educational issues faced by Roma households using data from the UNDP/ILO survey conducted in Bulgaria, the Czech Republic, Hungary, Romania and Slovakia in 2001.
