High‐Purity Single‐Photon Emission in the Telecom O‐Band from Droplet‐Epitaxy InAs Quantum Dots Integrated into a GaAs/AlGaAs Planar Microcavity on Vicinal GaAs(111)A Platform

Advanced Quantum Technologies, EarlyView.
High‐purity single‐photon emission at telecom O‐band is demonstrated from droplet‐epitaxy InAs quantum dots embedded in a GaAs/AlGaAs microcavity. Strain engineering via an InAlAs buffer enables broadband telecom emission with high purity, short lifetimes, and enhanced extraction.

Collecting Telecom Photons From Circular Bragg Gratings Using Optical Fibers and 3D Printed Micro‐Lenses

Advanced Quantum Technologies, EarlyView.
Coupling quantum light into optical single‐mode fibers is a strict requirement for quantum technological implementations. This work experimentally quantifies coupling efficiency of telecom single‐photons from circular Bragg grating cavities into silica fibers even equipped with 3D‐printed micro‐lenses.

Conceptualizing Resilience, Sustainability and Smartness for Building Fire Risk Management

Sustainable Development, EarlyView.
ABSTRACT Resilience, sustainability, and smartness (ReSuSm) within the building construction sector impact, or are impacted by building fires in one way or another. Hence, consideration of ReSuSm for building fire risk management (BFRM) is imperative to enhance safety and mitigate adverse impacts.

Balancing the Financial Trilemma: The Role of Financial Integration and Financial Development in Achieving Sustainable Development in Sub‐Saharan Africa

Sustainable Development, EarlyView.
ABSTRACT The financial trilemma (FT) highlights the challenge of balancing financial integration, financial development, and financial stability. A practical assessment of the FT is crucial for evaluating the current state of Sub‐Saharan Africa's (SSA) financial landscape and making substantial progress toward Sustainable Development Goals (SDGs ...

Towards Sustainable e‐Waste Practices: A Value‐Belief‐Norm Analysis of Mobile Phone Disposal in Ghana

Sustainable Development, EarlyView.
ABSTRACT Electronic waste (e‐waste) from mobile phones is a growing concern in resource‐constrained contexts, where limited infrastructure and regulatory enforcement promote reliance on informal systems. In Ghana, a rapidly expanding digital market, e‐waste accumulation poses significant environmental and social challenges.
