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

Propellants, 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 ...

Reduced‐Order Modeling of Energetic Materials Using Physics‐Aware Recurrent Convolutional Neural Networks in a Latent Space (LatentPARC)

Propellants, Explosives, Pyrotechnics, EarlyView.
Physics‐Aware Recurrent Convolutional Neural Networks (PARC) can reliably learn the thermomechanics of energetic materials as a function of morphology. This work introduces LatentPARC, which accelerates PARC by modeling the dynamics in a low‐dimensional latent space.

Evaluation of a High‐Performance Monopropellant Formed of Microencapsulated Hydrocarbon Fuels in Combination With Gelled Hydrogen Peroxide in a Strand Burner Setup

Propellants, Explosives, Pyrotechnics, EarlyView.
A high‐performance premixed monopropellant is prepared from hydrocarbon‐filled microcapsules and hydrogen peroxide. This propellant is burned in a strand burner, and the effect of different parameters on the burn rate is evaluated. ABSTRACT A dispersion of hydrocarbon‐fuel‐filled microcapsules in gelled hydrogen peroxide can form a premixed ...

Microphysical chemistry of fog–aerosol interactions over the northwest Atlantic Ocean during Fatima 2022

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Fifteen size‐resolved aerosol samples collected during marine fog, with adjacent ambient observations, show that coarse sea salt aerosol is rapidly grown and lost in the northwest North Atlantic Ocean except when subject to extreme winds. The persistence of fog in the absence of sea salt is determined by available fine‐mode aerosol, where greater ...

A Tool for Prioritizing Gravel Augmentation Reaches for Sediment Starved Rivers

River Research and Applications, EarlyView.
ABSTRACT Gravel augmentation is a widely used restoration technique used to improve habitat below dams, including salmonids spawning habitat. However, gravel augmentation can be cost‐prohibitive, and it is often unclear which stream segments have the highest potential to benefit spawning salmonids.
