Enhancing combustion performance of Al-H2O gelled propellants via polytetrafluoroethylene
Case Studies in Thermal EngineeringAluminum–water (Al-H2O) propellants are a novel class of solid propellants characterized by low cost and low signature observability. However, the inherently high aluminum content in these formulations often leads to severe agglomeration of aluminum (Al)

Impact of Environmental Exposure on Infant Sleep : The Exposome Approach
Journal of Sleep Research, EarlyView.This review explores how exposure to environmental pollutants during the first 1000 days of life may affect infant sleep. Evidence suggests potential links between chemical exposures and sleep disturbances, underscoring the need for more research on early‐life vulnerability and the impact of pollutants in air, diet, and breast milk.

Do deepfakes, digital replicas and human digital twins justify personality rights?
The Journal of World Intellectual Property, EarlyView.Abstract Unauthorised deepfakes are deeply problematic, from the spreading of misinformation to non‐consensual pornographic content. This paper asks whether deepfakes, digital replicas and human digital twins justify personality rights. To address this question, it examines the harms that deepfakes can cause through disinformation, demeaning content ...

From Palestine Ally to Zionist Partner: India‐Israel Relations, 2014–2025
Middle East Policy, EarlyView.Abstract India's pro‐Palestinian diplomatic posture, which held for nearly 70 years, has been transformed within a single decade of rule by the Hindu nationalist Bharatiya Janata Party (BJP), turning New Delhi into one of Israel's most consequential Asian partners. This shift has narrowed the coalition supporting the Palestinian cause.
