Assessment of the Interaction between Ammonium Dinitramide and Isocyanurate Bonding Agents for Application on Technologies of Composite Solid Propellants

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
This work investigates the interaction of two isocyanurate‐based bonding agents with ammonium dinitramide: triallyl isocyanurate and 1,3,5‐tris(2‐hydroxyethyl) isocyanurate, which contain alkene and hydroxyl functional groups in their side chains, respectively.

Retrospective image analysis for long‐term demography using Google Earth imagery

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
We demonstrate that high‐resolution Google Earth imagery, combined with minimal field validation, enables retrospective tracking of individual invasive plants. The image shows one of the monitored individuals of Opuntia sp. in Greece. Our approach reveals long‐term demographic patterns, recruitment dynamics, and spatial expansion without continuous ...

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...
