Crystal growth, structure, surface, optical, thermal, mechanical, magnetic, electrical investigations on cesium sulphate-doped 4-methoxyaniline: a single crystal for NLO and antimicrobial applications
“…The energy peak at 0.52 keV can be ascribed to the K-shell of oxygen, emissions at 1.0 keV, 8.7 keV, and 9.6 keV correspond to the Kshell of Zinc and is stated by references [10][11][12]. Peaks at 3.8 keV, 4.15 keV, 4.3 keV, 5.3 keV, and 5.55 keV can be directly linked to cesium's atomic structure, as evidenced by findings in references [30,31].…”
In this research study we report the successful preparation of cesium doped zinc metal oxide nanoparticles by solution combustion technique further incorporated into polyurethane films synthesized from bio-degradable castor oil, for study of piezo-conductive property. The composite films prepared with filler weight percentages of 0.5, 1.0, 2.0 and 4.0 are studied for structural, mechanical, thermal, electro-mechanical and weatherability properties. Studies revealed successful formation of urethane links and good dispersion of nanoparticles in the prepared films. Films under tensile and compression loading showed promising electro active results with maximum volume conductivity values of 1.226E−7Scm−1 at 30N compression load. The developed films show good compatibility to be employed in corrosive and acidic environments with safe working temperature upto 160°C.

“…At present, research on slope monitoring and early warning is developing rapidly at home and abroad, especially in the aspect of wireless data transmission. Therefore, it is of great significance to introduce wireless SN technology into the design and research of the online monitoring and early warning system for RE mine slopes (Ilyin, 2022;Thilaga, et al, 2022). Sakthivel et al (2022) studied the synchronization problem of the complex dynamic network (CDN) with non-linearity, uncertainty, time-varying input delay, and interference.…”
Ionic rare earth (RE) mines use the in situ leaching (ISL) method to operate, but after investigation, it is found that the geological damage caused by RE mines is still serious in recent years. The structure is damaged, which affects the stability of the mine slope and even causes geological disasters such as landslides and collapses to a certain extent, which has a huge impact on the lives of local people. Therefore, it is very important to analyze the slope stability of RE mines. In this study, indoor similarity simulation experiments were conducted using the sensor network (SN) of non-linear data analysis, and its stability of the ISL of ionic RE ore bodies was studied. In addition, an indoor column leaching simulation experiment was carried out to observe the internal fine and microstructure of the ore sample during the whole leaching process using nuclear magnetic resonance (NMR) under the conditions of magnesium sulfate solution and water leaching, respectively. The evolution mechanism of the pore structure was analyzed during the leaching process. The experiments showed that during the whole leaching process, the ore body reaches saturation in the early stages, resulting in a sharp increase in the porosity of the ore sample within the first 1 h due to seepage. Subsequently, the porosity of each sample increases, indicating that the seepage of the leaching solution inside the sample has reached a relatively stable state.
