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

Propellants, 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.

Dinuclear Lanthanide (III) coordination polymers in a domino reaction [PDF]

, 2015
A systematic study was performed to further optimise the catalytic room-temperature synthesis of trans-4,5- diaminocyclopent-2-enones from 2-furaldehyde and primary or secondary amines under a non-inert atmosphere. For this purpose, a series of dinuclear

From Hemp Bast to Lyocell Fiber: Sustainable Process Optimization for Lyocell‐Grade Dissolving Pulp

Journal of Applied Polymer Science, Volume 143, Issue 16, April 20, 2026.
This study presents a sustainable method to produce lyocell‐grade dissolving pulp from Canadian hemp bast fibers. A simplified alkali‐chelation‐bleaching process, free from sulfur and chlorine, yielded high α‐cellulose pulp with low lignin and hemicellulose content. The pulp was successfully spun into continuous hemp‐based lyocell fibers, demonstrating

Efficient One-Dimensional Network Design Method for Underwater Acoustic Target Recognition

Journal of Marine Science and Engineering
Many studies have used various time-frequency feature extraction methods to convert ship-radiated noise into three-dimensional (3D) data suitable for computer vision (CV) models, which have shown good results in public datasets.

Influence of temperature on high molecular weight poly(lactic acid) stereocomplex formation [PDF]

, 2019
The influence of temperature on the formation of high molecular weight poly(lactic acid) (PLA) stereocomplex was studied by evaluation of the precipitates from dioxane solutions of PLA enantiomers (PLLA and PDLA).

Light‐Induced Precipitation of an Inorganic Phosphate for Direct Writing of Thin Films and Templating Complex Mineral Morphologies

Advanced Materials Interfaces, Volume 13, Issue 3, 3 February 2026.
Photoinduced patterning of inorganic materials promises advanced functionality, but often suffers from granular structures. Here, UV‐triggered dephosphorylation is used to guide the precipitation of barium phosphate with spatial control and structural continuity.

Environmental Risk Assessment and Anti‐Corrosion Efficacy of Safe‐by‐Design Nitrite‐Based Nanomaterials for Maritime Applications

Nano Select, Volume 7, Issue 2, February 2026.
The environmental behavior and impact of anti‐corrosion nanoadditives, ZnAl‐NO2 and MgAl‐NO2 layered double hydroxides (LDH), are assessed under marine conditions. These nanomaterials show instability in water but exhibit no or low toxicity to most tested marine species.
