Hypergolic droplet‒film interaction dynamics at high temperatures

Droplet, EarlyView.
The whole reaction process can be distinctly identified as three stages based on the corona size and the temperature temporal evolution. In the coalescence regime, T* maintains quasi‐stationary values during initial contact, corresponding to hydrodynamic coalescence process. Consequently, the first stage is defined as the inertia‐dominant stage. In the

Factorial Analysis of the Influence of Both Water and Oxygen on Extruded Double Base Rocket Propellant Decomposition

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT The decomposition mechanisms of double base rocket propellants are well known and reported, but the influence of atmospheric conditions such as water and oxygen is poorly understood. In this work, the influence of water and oxygen on an extruded double base (EDB) rocket propellant aged between 70 and 100°C was examined using heat flow ...

HOW DATA CENTERS HAVE COME TO MATTER: Governing the Spatial and Environmental Footprint of the ‘Digital Gateway to Europe’

International Journal of Urban and Regional Research, EarlyView.
Abstract Data centers, the material backbone of smart cities, power the digital economy and advanced digital services. Metaphors of ‘the cloud’ and ‘cloud computing’ obscure the massive computing and storage infrastructures, the resource flows and the land uses they mediate.

Antinomies of Alignment Redux: The United Arab Emirates and the United States

Middle East Policy, EarlyView.
Abstract Over the past three decades, the United Arab Emirates has forged a sturdy bilateral security alignment with the United States. It has also pursued foreign policies that conflict with US interests in the Gulf and the broader Middle East. This contradiction is usually attributed to a hedging strategy.
