摘要

摘要 本研究旨在探讨壳聚糖(Chi)掺入不同镧系氧化物(LnO)(如铈、钕、钐、铕、钆、镝和钬氧化物)对其热力学性质的影响。特别是对镧系元素收缩的影响(即质量和尺寸之间的竞争)进行了研究和报告。本研究介绍了一种计算 Chi-LnO 复合材料各种物理性质的方法,该方法基于有关掺杂壳聚糖的 LnO 的质量和尺寸的折射率、密度、粘度和超声波速度的实验值。这些特性对于理解复合材料的行为和特性起着至关重要的作用。计算过程包括根据给定的实验数据计算出介电常数、分子间自由路径长度、弛豫时间、超声衰减、相对关联、表面张力、吉布斯自由能和非线性参数等物理特性,并对结果进行详细讨论。

Unusual behavior in thermodynamical properties of chitosan-lanthanide oxide composites: competition between the size and mass
Abstract The objective of this investigation is to explore how doping chitosan (Chi) with different lanthanide oxides (LnO) such as cerium, neodymium, samarium, europium, gadolinium, dysprosium, and holmium oxides affects its thermodynamic properties. Especially the effect of lanthanide contraction which is the competition between mass and size has been investigated and reported. The investigation describes a method for calculating various physical properties of a Chi-LnO composite material based on experimental values of refractive index, density, viscosity, and ultrasonic velocity concerning the mass and size of the LnO doped with chitosan. These properties play crucial roles in understanding the behavior and characteristics of composite materials. The process involves deriving the physical properties such as dielectric constant, intermolecular free path length, relaxation time, ultrasonic attenuation, relative association, surface tension, Gibbs free energy and non-linearity parameters are calculated from the experimental value of the refractive index, density, viscosity and ultrasonic velocity properties from the given experimental data and results are discussed in a detailed manner.
