Protected and productive: How greenhouses should deliver UK food security

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The United Kingdom produces less than 20% of its fruit and ~50% of its vegetables, leaving it highly import dependent and vulnerable to supply chain disruptions. Our study maps 2085 ha of existing greenhouses, over 70% more than 40 years old, and identifies where modern infrastructure could expand production.

Comparative Assessment of Energetic Plasticizers Including NFPEG3N3 in a GAP/HMX Formulation: Mechanics, Stability, Combustion, and Performance

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT We examine the new energetic plasticizer 3‐(2‐(2‐(2‐azidoethoxy)ethoxy)ethoxy)‐4‐nitro‐1,2,5‐oxadiazole (NFPEG3N3), three reference compounds (BDNPA/F, Bu‐NENA, and DNDA‐57), and a plasticizer‐free control in a fixed HMX/GAP composite. NFPEG3N3 provides the strongest low‐temperature properties, yielding the lowest formulation glass transition ...

Characterization of Structure, Properties, and Energetic Performance of a 1:1 Ammonium Dinitramide‐3,4‐Diaminofurazan Cocrystal

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
Ammonium dinitramide (ADN) and 3,4‐Diaminofurazan (DAF) form a 1:1 energetic cocrystal. We report its crystal structure and spectroscopic signature and evaluate thermal stability, decomposition behavior, hygroscopicity, and combustion properties. Propellant performance calculations benchmark the material against guanylurea dinitramide (GuDN) and ...
