Two new initiatory molecules, e.g. rubidium and cesium salts of 4,6-dinitrobenzofuroxan (DNBF) have been prepared by reacting sodium salt of 4,6-dinitrobenzofuroxan (DNBF) with rubidium nitrate and cesium nitrate, respectively, at 60 degrees C in aqueous medium. The characterisation of compounds by IR, (1)H-NMR, elemental analysis and metal content is described along with some of the evaluated thermal and explosive properties. The results indicate that cesium salt of DNBF (Cs-DNBF) appears promising initiatory and may suitably replace potassium salt of DNBF (K-DNBF), being used currently in initiatory compositions.

The impact of light radiation, a predominant energy release mechanism in nuclear explosions, on material properties is of critical importance. This investigation employed an artificial light source to replicate the effects of nuclear explosion radiation and utilized a physical information neural network (PINN) to examine the temperature evolution and corresponding changes in the mechanical properties of carbon fiber/epoxy composites (CFEC). A light source simulating nuclear explosion's light radiation was built to irradiate the CFEC, then measure the reflection spectrum and temperature of samples.

Heating techniques have underpinned the progress of the material and manufacturing industries. However, the explosive development of nanomaterials and micro/nanodevices has raised more requirements for the heating technique, including but not limited to high efficiency, low cost, high controllability, good usability, scalability, universality, and eco-friendliness. Carbothermal shock (CTS), a heating technique derived from traditional electrical heating, meets these requirements and is advancing at a high rate.

During maritime operations, extreme events such as explosions, grounding, and seal failures can cause water ingress into lubricant compartments, forming oil-water emulsions that significantly affect the lubrication performance of ship stern bearings. Existing studies mainly focus on low water content, with limited exploration of the impact of high water content on lubrication performance. To address this gap, viscosity measurements of oil-water mixtures were conducted, and an emulsification viscosity equation applicable to varying water contents was derived.

The waste Lentinus edodes stalks from Lentinus edodes processing were used as raw materials by the steam explosion to prepare modified Lentinus edodes stalks dietary fiber and combined with tea polyphenols to form the SE-DF-tea polyphenols complex (SE-DF-TPC). The SE-DF-tea polyphenols mixture (SE-DF-TPM) was prepared according to the complex's optimal adsorption conditions. Fluorescence microscopy, Fourier transform infrared spectroscopy, particle size measurement, thermogravimetric analysis, and X-ray diffraction were used to analyze its structure, and the thermal stability of the complex and its adsorption capacity for lipids, cholesterol, and cholates were studied.
