Insights From the Alphasat Aldo Paraboni Experiment at Tito Scalo and Spino d'Adda: Characterizing Scintillation and Rain Attenuation at Ka‐ and Q‐Band Frequencies

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT We present experimental results on the relationship between rain attenuation and simultaneous scintillation during rain events, based on beacon signal measurements at 19.7 (Ka‐band) and 39.4 GHz (Q‐band) from the geosynchronous Alphasat satellite (25° E), received at two Italian ground stations, Spino d'Adda (42.1° slant path) and Tito Scalo ...

Localising the Sustainable Development Goals. A Place‐Based Analysis of Sustainable Development in Rural and Urban Areas

open access: yesSustainable Development, EarlyView.
ABSTRACT There are increasing calls for a place‐based approach towards the Sustainable Development Goals that show their territorial diversity at subnational level. Based on 33 indicators, covering 13 SDGs and aggregated in three sub‐indexes (economy, social and environment), this paper develops a Sustainable Development Index for Rural and Urban Areas

Does Carbon Intensity Affect the Cost of Equity? An Empirical Study From Mexico

open access: yesSustainable Development, EarlyView.
ABSTRACT Climate change poses significant risks for companies, particularly in emerging countries like Mexico, where sustainability perceptions are evolving. This study analyzes how carbon emissions affect the cost of equity capital (CoE) for Mexican firms.

The Strategic Logic of Biodiversity: Why Firms Invest in Nature‐Based Initiatives

open access: yesSustainable Development, EarlyView.
ABSTRACT Biodiversity loss poses profound strategic and operational challenges for firms, yet management research offers limited evidence on which organisational mechanisms effectively reduce corporate biodiversity impacts. This study introduces the Biodiversity Strategy Configuration Framework (BSCF) to enhance the understanding of firm‐level ...

The Dynamic Impact of the Energy Transition on Food Security in Developing Countries

open access: yesSustainable Development, EarlyView.
ABSTRACT In the context of persistent food insecurity and the global push for the transition toward clean energy in developing countries, understanding the association between clean energy access and food affordability is increasingly important to inform multisectoral policy interventions. Against this background, this study explores the dynamic impact

Zincophilic Porous Carbon Interface with Dendrite‐Free Zinc Deposition via Selective Ion Regulation for Aqueous Zinc Ion Batteries

open access: yesSmall, EarlyView.
A multifunctional zincophilic porous carbon (ZPC) layer is engineered as a protective layer for aqueous zinc‐ion batteries (AZIBs). The ZPC layer guides Zn2+ diffusion and desolvation through ion adsorption sites. Also, its polar functional groups enhance interfacial adhesion and redox activity.

Scalable Room‐Temperature Terahertz Graphene Cameras

open access: yesSmall Methods, EarlyView.
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...
