Vickers Microhardness as a Viable Mechanical Property Measurement Technique for High Explosive Materials

Propellants, Explosives, Pyrotechnics, EarlyView.
There are multiple drivers for the development of reliable mechanical property techniques for high explosive (HE) samples, particularly smaller HE samples. While Vickers microhardness is a commonly used technique for mechanical characterization in metals and other materials, there has been little work using this technique for HE materials, particularly

Effect of Hydroxyl‐Terminated Polybutadiene Grade on Rheology and Settling of High‐Solids Mixtures of Mock Propellants

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT The most common binder used in composite rocket propellants is based on the pre‐polymer hydroxyl‐terminated polybutadiene (HTPB). It has been shown to have excellent mechanical properties and a long life once crosslinked, and studies have examined the kinetics of crosslinking and pot life of energetic formulations with HTPB.

Evolution of sea fog based on meteorological and oceanographic observations during FATIMA Yellow Sea campaign

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study presents a conceptual framework linking sea‐water temperature Tw gradients to the formation and persistence of sea fog in the southeastern Yellow Sea. Over cold waters maintained by tidal mixing, downward latent heat flux enhances lower‐level stability and sustains persistent sea fog, whereas over warmer waters, upward fluxes and thermal ...

Enhancing Drone Light Shows Performances: Optimal Allocation and Trajectories for Swarm Drone Formations

Journal of Field Robotics, EarlyView.
ABSTRACT Drone light shows (DLShows) represent a rapidly growing application of swarm robotics, creating captivating aerial displays through the synchronized flight of hundreds or thousands of unmanned aerial vehicles (UAVs) as environmentally friendly and reusable alternatives to traditional pyrotechnics.

Mapping Scytonemin Pigment Content and Biocrust Functional Indicators Using High‐Resolution Multispectral Imagery

Remote Sensing in Ecology and Conservation, EarlyView.
We demonstrate that high‐resolution multispectral imagery combined with machine learning can accurately predict key biocrust functional indicators, particularly the UV‐protective pigment scytonemin, across dryland ecosystems. Using fine‐scale imagery acquired in the Chihuahuan Desert and Colorado Plateau, we identified spectral bands strongly ...
