Summary: This study focuses on the heat transfer mechanism and cook-off response characteristics of a complex structure with nineteen tubular cluster double-base propellants. The researchers develop a three-dimensional unsteady heat transfer model with a chemical reaction mechanism to capture the fundamental thermal phenomena during the heating process. They find that both chemical reactions and heat transfer mechanism play important roles in the cook-off response, and the heating rate also affects the response parameters.

Summary: Nanocrystalline cellulose, with its unique physical and biological properties, has gained attention from researchers. The utilization of agricultural waste, such as sugarcane bagasse and banana peels, for the production of nanocrystalline cellulose can help protect the environment. Researchers optimized the concentration of these nanocrystalline cellulose materials as disintegrants in the preparation of Diclofenac potassium IR tablets. The tablets showed promising results and can be explored as a new disintegrant for solid oral dosage forms.

Summary: The effects of yttrium (Y) addition on the creep and tensile properties of Hastelloy-X manufactured by selective laser melting (SLM) process were investigated. The addition of yttrium improved the performance of the alloy by reducing silicon content, eliminating cracking, and enhancing tensile elongation and creep properties. After post-processing solution heat treatment (ST), yttrium-added specimens exhibited superior creep properties due to grain morphology changes and the formation of carbides and oxides at grain boundaries.

Summary: A continuous adsorption analysis for the removal of sodium ions from seawater using synthesized zeolite A was conducted in a fixed-bed column. The study investigated the effect of flow rate, sodium ion concentration, and zeolite bed height on the removal process. Breakthrough curve analysis was used to model the adsorption isotherm, and kinetic models including the Thomas, Adams-Bohart, and Yoon-Nelson models were used to analyze the particles' movement. The results showed that the breakthrough capacity decreased with increasing flow rate and decreasing sodium ion concentration, while it increased with increasing bed height. The Adams-Bohart model demonstrated better performance in describing the kinetic behavior compared to the other models. The study highlights the potential use of zeolite A in desalination processes for extracting sodium ions from seawater.

Summary: This study systematically investigates the effects of Al, Cr, Mo, Nb, Ta, Ti, V, and Zr elements on the oxidation of RCCAs. It is found that Al, Cr, and Ti can enhance the oxidation resistance of RCCAs, while Zr and V result in severe internal oxidation. Mo is effective in suppressing internal oxidation, but forms non-protective compounds. Ta is more beneficial for reducing the oxidation mass gain.

Summary: Damage resistance of carbon fibre reinforced composites is crucial and can be improved by modifying the epoxy matrix with amine functionalized multi walled carbon nanotubes. Laminates with different nanotube concentrations were fabricated and showed enhanced load bearing capacity, toughness and damage resistance. Matrix cracking was suppressed and delamination area was reduced. The improvement in damage resistance was attributed to the interfacial interactions and energy absorbing microstructure.
