Identifying Suitable Front Contacts for High‐Efficiency Cd(Se,Te) Solar Cells on Space‐Qualified Cover Glass

Progress in Photovoltaics: Research and Applications, EarlyView.
Front contact selection governs interfacial stability in CdTe‐based (Cd(Se,Te)) solar cells on ultra‐thin space‐qualified cover glass. Optimized TCO/emitter combinations suppress interdiffusion and deliver up to 16.2% AM0 efficiency with high specific power, demonstrating strong potential for lightweight space photovoltaics.

From wild to tamed: Reimagining novel crops through omics and local plant diversity

PLANTS, PEOPLE, PLANET, EarlyView.
The global food system faces growing pressure from climate change, biodiversity loss, and rising nutritional demands. Agriculture has increased yields but reduced crop diversity, flavor, and nutritional quality, leaving societies vulnerable and dependent on a narrow set of staple species.

Energy Dissipation in Strong Collisionless Shocks: The Crucial Role of Ion-to-electron Scale Separation in Particle-in-cell Simulations

The Astrophysical Journal Letters
Energy dissipation in collisionless shocks is a key mechanism in various astrophysical environments. Its nonlinear nature complicates analytical understanding and necessitates particle-in-cell (PIC) simulations. This study examines the impact of reducing

Observations of the spatial and temporal structure of field-aligned beam and gyrating ring distributions at the quasi-perpendicular bow shock with Cluster CIS [PDF]

Annales Geophysicae, 2001
During the early orbit phase, the Cluster spacecraft have repeatedly crossed the perpendicular Earth’s bow shock and provided the first multi-spacecraft measurements. We have analyzed data from the Cluster Ion Spectrometry experiment (CIS), which

Assessing National Sustainability Transitions in Europe: A Dynamic MCDA and Clustering‐Based Approach

Sustainable Development, EarlyView.
ABSTRACT The study evaluates the sustainable development of 42 European countries using a multi‐criteria decision analysis (MCDA) approach, based on 29 indicators covering the economic, social, and environmental pillars. All three pillars are assessed both individually and in consolidated form to provide a comprehensive view of countries ...

From Proxies to System State: Defining Sustainability Management Against Symbolic Progress

Sustainable Development, EarlyView.
ABSTRACT Sustainability in management is often measured through scores, ratings, and disclosure narratives that can reward symbolic progress while leaving underlying social‐ecological conditions unchanged. This perspective paper offers a definition of Sustainability Management as how organizations plan, organize, lead, and control (four management ...

On the Formation of Super-Alfvénic Flows Downstream of Collisionless Shocks

The Astrophysical Journal
Super-Alfvénic jets, with kinetic energy densities significantly exceeding that of the solar wind, are commonly generated downstream of Earth's bow shock under both high- and low-beta plasma conditions. In this study, we present theoretical evidence that

Spatial distribution of upstream magnetospheric ≥50 keV ions [PDF]

Annales Geophysicae, 2000
We present for the first time a statistical study of \geq50 keV ion events of a magnetospheric origin upstream from Earth's bow shock. The statistical analysis of the 50-220 keV ion events observed by the IMP-8 spacecraft shows: (1) a dawn-dusk ...

Incremental Shifts, Strategic Orbits: The Evolution of EU Space Policy Through Gradual Security Linkages

Global Policy, EarlyView.
ABSTRACT This article examines the evolution of European Union (EU) space policy through the lens of historical institutionalism, highlighting how security and defence considerations have been incrementally integrated into a domain originally framed as civilian and scientific.
