Engineering Photonic Pigments From Titania–Block Copolymer Composites

open access: yesMacromolecular Rapid Communications, EarlyView.
Ligand‐functionalized TiO2 nanoparticles selectively partition into P2VP‐rich lamellae of onion‐like PS‐b‐P2VP microspheres, increasing refractive index contrast while preserving concentric order through controlled self‐assembly. The resulting dry photonic pigments display defined Bragg reflections and angle‐robust structural color.

Leveraging Public Transit for Robotic Deliveries: A Column Generation Approach

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT Autonomous mobile robots (AMRs) are small, electric, wheeled vehicles that operate at pedestrian speeds. In the last‐mile delivery service considered in this study, a fleet of AMRs is deployed across multiple recharging depots within a service area, from which they depart to perform point‐to‐point deliveries. We consider an operational setting

Climate Crisis, Human Mobility and Security Challenges in the MENA Region: Implications for Sustainable Development and Regional Stability

open access: yesSustainable Development, EarlyView.
ABSTRACT This study examines the interplay between climate change, violent conflict and forced migration in the Middle East and North Africa (MENA), focusing on asylum flows to the European Union (EU). By integrating high‐resolution climate, conflict and socioeconomic data spanning 2000 to 2023, we develop a comprehensive empirical framework to ...

Transparency, Sustainable Governance and Digital Accessibility in Municipalities: A Machine Learning Approach

open access: yesSustainable Development, EarlyView.
ABSTRACT Achieving the Sustainable Development Goals (SDGs) requires transparent and accountable local governments, yet little is known about the structural drivers of municipal transparency. This study introduces a machine learning approach to predict municipal transparency using the Bidimensional Transparency Index (BTI), which measures both the ...

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

open access: yesSustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

Seeded‐Growth of ZIF‐8 onto Magnetic Nanoparticles: Smart Nanocarriers with Ultrahigh Drug Loading for AMF‐Triggered Release

open access: yesSmall, EarlyView.
We developed core‐shell iron oxide@ZIF‐8 magnetic‐MOF nanohybrids via a seeded growth method for magnetic hyperthermia‐triggered drug delivery. Cubic cores and thinner shells maximized heating. In‐situ doxorubicin encapsulation achieved 98% loading, better than surface encapsulation. Polymer coating improved stability.

Seeded Growth of Plasmonic Core‐Shell NU‐1000 NanoMOFs With Intracellular Optical Readout

open access: yesSmall, EarlyView.
Seed‐mediated growth yields plasmonic core‐shell nanocomposites by encapsulating gold nanoparticles within NU‐1000 nanoMOFs, preserving morphology and optical response. The materials exhibit tunable photoluminescence quenching, efficient photothermal heating, and SERS activity.
