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 ...

Sulfonated, Disulfide‐Bridged Polymer Networks for Atmospheric Water Harvesting

Small, EarlyView.
Atmospheric water harvesting is a promising solution to the water crisis. Here, disulfide‐containing hyper‐crosslinked‐style polymers are prepared by combined Friedel–Crafts alkylation and thiol self‐condensation. Exhibiting exceptional uptake capacities, the polymers demonstrate dynamic bonding behavior.

Unraveling Water Sorption in Single‐Crystal MOFs: Insights from Spectroscopy and Modeling on the Role of Structure, Composition, and Guest Molecules

Small, EarlyView.
Water scarcity drives the search for efficient atmospheric water harvesting (AWH) materials. This study explores the impact of metal substitution (Zr to Hf) and linker exchange (fumaric to trimesic acid) on the water sorption performance of MOF‐801 and MOF‐808.

A curved multi-component aerosol hygroscopicity model framework: Part 1 – Inorganic compounds [PDF]

Atmospheric Chemistry and Physics, 2005
A thermodynamic modelling framework to predict the equilibrium behaviour of mixed inorganic salt aerosols is developed, and then coupled with a technique for finding a solution to the Kohler equation in order to create a diameter dependent hygroscopic ...

Bottom‐Up Assembly of Amorphous Metal–Organic Frameworks From Proton Conductive Metal–Organic Polyhedra

Small, EarlyView.
Structural control in amorphous MOFs (aMOFs) remains challenging compared to their crystalline counterparts. We report a bottom‐up strategy using metal‐organic polyhedra as predefined building units. By crosslinking these clusters, we preserve intrinsic node functionality within aMOFs, achieving proton conductivity up to 4.8 mS cm−1 at 85°C and 90% RH,

Influence of Viscous Dissipation on Wear Behavior and Hardness Evolution of Tool Steels in Glass‐Fiber‐Reinforced Polymer Processing

steel research international, EarlyView.
Tool steels tested under injection molding conditions with glass‐fiber‐reinforced polymers, revealing how viscous dissipation drives hardness loss, even in PM grades. A sharp rise in wear with increasing injection volume rate and thermomechanical load uncovers striking material differences.
