Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Engineering Pendant Group Chemistry to Control Hydrophilicity and Oxidative Degradation of Thioketal‐Based Biomaterials

Advanced Functional Materials, EarlyView.
Thioketal (TK) polymers are promising biomaterials due to their selective biodegradation by reactive oxygen species (ROS), but they respond slowly to physiologic doses of ROS. Here, the TK bond's pendant groups are modified to enhance the degradation of TK‐based implants both in vitro and in vivo.

Intercultural and Interreligious Dialogue Competences in Adolescents in Barcelona and Melilla (Spain)

Religions
Contemporary societies are increasingly multireligious, multiethnic, and multicultural, but to what extent are they ready for coexistence? This paper evaluates the competencies for intercultural and interreligious dialogue in two very different contexts:

Ultrasmall High‐Entropy Materials: Nanoscale Effects, Synthesis, and Mechanistic Insights

Advanced Functional Materials, EarlyView.
This review article focuses on sub‐10 nm high‐entropy materials that combine nanoscale design with complex compositions for next‐generation applications. ABSTRACT Ultrasmall high‐entropy nanomaterials (USHENMs, <10 nm) merge multicomponent chemistry with size‐dependent effects, forming a distinct class of materials with unprecedented properties.

Artery‐on‐Chip Demonstrates Mechanical and Functional Features of Healthy and Diseased Living Smooth Muscle Tissue

Advanced Functional Materials, EarlyView.
This article details the development of an artery‐on‐chip platform for in vitro arterial disease modeling and therapeutic discovery. It describes the fabrication of a fibrin biomaterial scaffold seeded with iPSC‐derived smooth muscle and endothelial cells, mimicking native artery properties. Two genetic disease models showcase the platform's ability to

All-cause mortality, age at arrival, and duration of residence among adult migrants in Sweden: A population-based longitudinal study

SSM: Population Health, 2018
Background: A mortality advantage has been observed among recently arrived immigrants in multiple national contexts, even though many immigrants experience more social disadvantage compared to natives.

Nano‐Scale Characterization of Impurities Segregation in Solid Oxide Electrolysis Cells

Advanced Functional Materials, EarlyView.
Cathodic polarization induces impurity segregation in Ni, forming an amorphous Na─Al─Si─O amorphous phase at grain boundaries. Under ultralow oxygen partial pressure, multiple elements dissolve, migrate, and reoxidize within the metal. A patterned model system provides direct nanoscale evidence, clarifying the mechanism of polarization‐driven impurity ...

Crossing alone the Mediterranean sea. Some critical issues about unaccompanied minors in Europe

REMHU: Revista Interdisciplinar da Mobilidade Humana
Despite the increasing social impact of unaccompanied migrant minors (UAMs) in many European Union (EU) member states, EU regulations on UAMs are still inadequate and the necessary protection measures are thus insufficient.

Unaccompanied migrant minors (UAMs) in Italy and in Spain

, 2023
In any European Union Member State, unaccompanied migrant minors (UAMs) represent a complex subject that requires a multifaceted approach, encompassing factors such as the characteristics of migratory flows, reception policies, legal frameworks, and access to services. The status of UAMs is split between being a “minor” and therefore a direct recipient
