A newly proposed mathematical approach to plastic flow, holding from yield to fracture, of a fine-grained polycrystal with no voids or cracks is reviewed and applied to commercial steels. The formalism models the polycrystal by a continuum array of random deformable polyhedra leaving no voids between them, which can slide past each other along the shared faces when the shear stress resolved in the face plane exceeds a finite threshold. Grain reshaping for preserving matter continuity induces local forces assumed much weaker than those causing sliding. The relative velocity of adjacent sliding grains is taken as proportional to the local shear stress resolved in the common boundary plane. Explicit equations are derived for the plastic deformation, from yield to fracture. The analysis of mechanical tests of two commercial stainless steels is shown to illustrate how well the theory agrees with practice.

本文对一种新提出的数学方法进行了评述，该方法适用于没有空隙或裂缝的细粒度多晶体从屈服到断裂的塑性流动。这种形式主义是通过一个由随机可变形多面体组成的连续阵列对多晶体进行建模，这些多面体之间不留空隙，当面平面上的剪应力超过一个有限阈值时，这些多面体可以沿着共享面相互滑过。为保持物质连续性而进行的晶粒重塑会产生局部作用力，这种作用力假定比导致滑动的作用力弱得多。相邻滑动晶粒的相对速度与共同边界平面上的局部剪应力成正比。得出了从屈服到断裂的塑性变形的显式方程。对两种商用不锈钢的机械测试分析表明了理论与实践的吻合程度。

SiN_x films were grown on silicon substrates by Radio Frequency (RF) magnetron sputtering deposition. The effect of nitrogen flow on the structural and optical properties of the obtained films was investigated using X-ray diffraction, Scanning Electron Microscopy (SEM), UV–Vis–NIR spectrophotometer and spectroscopic ellipsometer, respectively. XRD spectra of the films showed that all films belong to amorphous structure. SEM photographs of SiN_x films were analyzed. As a result of the analysis, it was observed that the surfaces of the films had a homogeneous and smooth structure as the nitrogen flow increased. The total and diffuse reflectance spectra of the films were measured and the energy band gaps of the films were determined using the Kubelka-Munk function by using the diffuse reflectance. It was observed that the energy band gap changed as the nitrogen percentage increased. The refractive index of all films was obtained as a function of temperature using a spectroscopic ellipsometer. In the second part of this study, we focused on predicting the temperature dependent refractive indices of the nitrogen flow-dependent films using Artificial Neural Networks (ANN). For the training of the ANN model, wavelength and temperature values from experimental data were used as input and refractive index as output parameters. The simulation and prediction results obtained from this model are compared with the experimental data and interpreted. It is concluded that the ANN approach is suitable for simulating and predicting the temperature dependent refractive index. The models successfully trained with ANN will be especially preferred for predicting the refractive indices of SiN_x films, which cannot be measured experimentally, thus providing predictions in non-experimental ranges. In particular, the results obtained by focusing on the ability of the developed artificial neural network (ANN) models to predict the optical properties of SiN_x films and their potential to provide information in non-experimental conditions, offer a new approach to quickly and effectively evaluate the optical properties of SiN_x films. This approach reveals the importance of artificial intelligence-based methods in materials characterization studies.

通过射频（RF）磁控溅射沉积法在硅基底上生长了氮化硅薄膜。使用 X 射线衍射、扫描电子显微镜（SEM）、紫外-可见-近红外分光光度计和椭偏仪分别研究了氮气流对薄膜结构和光学特性的影响。薄膜的 X 射线衍射光谱显示，所有薄膜都属于无定形结构。对 SiNx 薄膜的扫描电镜照片进行了分析。分析结果表明，随着氮气流量的增加，薄膜表面呈现出均匀光滑的结构。测量了薄膜的全反射和漫反射光谱，并利用漫反射利用库伯卡-蒙克函数确定了薄膜的能带隙。结果表明，能带隙随着氮比例的增加而变化。使用分光椭偏仪获得了所有薄膜的折射率与温度的函数关系。在本研究的第二部分，我们重点使用人工神经网络（ANN）预测氮气流动相关薄膜随温度变化的折射率。在训练 ANN 模型时，实验数据中的波长和温度值被用作输入参数，折射率被用作输出参数。该模型获得的模拟和预测结果与实验数据进行了比较和解释。结论是，ANN 方法适用于模拟和预测随温度变化的折射率。在预测无法通过实验测量的 SiNx 薄膜的折射率时，使用 ANN 成功训练的模型将尤其受到青睐，从而提供非实验范围内的预测结果。特别是，通过关注所开发的人工神经网络（ANN）模型预测氮化硅薄膜光学特性的能力及其在非实验条件下提供信息的潜力而获得的结果，为快速有效地评估氮化硅薄膜的光学特性提供了一种新方法。这种方法揭示了基于人工智能的方法在材料表征研究中的重要性。

Recent years have seen greater interest in manipulating vortex states in magnetic nanostructures for non-volatile memory and logic networks. We show how reducing saturation magnetization locally in ferromagnetic thick nanodot vortex-based spin-torque nano-oscillators modulates their frequency using micromagnetic simulations. When a spin-polarized current and a static in-plane magnetic field are applied to the vortex core of an isolated thick nanodot, the uniform gyrotropic modes and the first higher-order gyrotropic mode resonate at different frequencies in various saturation magnetization areas. The intensity of the first higher-order mode gets almost suppressed in areas with modified saturation magnetization. With linewidths ranging from 25 to 70 MHz with the considered dimensions, these small spin-torque vortex-oscillator devices made of thick Permalloy nanodots seem promising for use in gigahertz signal processing. Our study suggests that locally modifying saturation magnetization may be a cost-effective technique to build dense oscillator and array networks for neuromorphic computing without lithographical fabrication stages.

近年来，人们对操纵磁性纳米结构中的涡旋态以实现非易失性存储器和逻辑网络越来越感兴趣。我们通过微磁模拟展示了如何局部降低铁磁性厚纳米点涡旋型自旋力矩纳米振荡器的饱和磁化，从而调制其频率。当对孤立厚纳米点的涡旋核心施加自旋极化电流和静态面内磁场时，在不同的饱和磁化区域，均匀陀螺回转模式和第一高阶陀螺回转模式会产生不同频率的共振。在饱和磁化改变的区域，第一高阶模式的强度几乎被抑制。在所考虑的尺寸下，这些由厚坡莫合金纳米点制成的小型自旋力矩涡旋振荡器器件的线宽范围为 25 到 70 MHz，似乎很有希望用于千兆赫信号处理。我们的研究表明，局部改变饱和磁化可能是一种经济有效的技术，可用于构建神经形态计算所需的密集振荡器和阵列网络，而无需平版印刷制造阶段。

In-medium effective carriers with position-dependent mass in a multishell heterostructure are analytically studied. We obtain the exact spectrum of three-dimensional bound eigenstates and the scattering wave-functions for several von Roos ordering classes. Ascribing a continuously varying mass to the carriers in a multilayer type spherical system we use our solutions to compute optical properties such as the absorption coefficients and refraction indices of a nanometric heterostructure.

Molecular dynamics simulations are used to study the aggregation dynamics of water-in-oil emulsion droplets under an electric field, and to analyze the effects of electric field strength, type, droplet position, and ionic concentration on their kinematic properties. The best droplet aggregation is observed at E = 0.03V/Å for DC field condition, and E = 0.045V/Å - 80ps for rectangular AC field condition. The rectangular alternating current (AC) field is able to merge the droplets farther away from the center of mass, but the two fields are not able to merge when the angle between the center of mass of the droplets and the electric field force is ≥ 35.54°. For different ion concentrations, t_40N < t_20N < t_60N < t_0N in the DC field and t_20N < t_40N < t_0N < t_60N in the rectangular AC field, and for the same ion concentration, the rectangular AC field takes longer time to merge.

This study aims to evaluate the free vibrational response of embedded restrained nanobeams enriched by nanocomposites based on an exact Fourier series approach. In order to capture the small-scale effects on the dynamical response, Eringen's differential form of nonlocal elasticity is used which employs a scale (nonlocal) parameter. Within the framework of Rayleigh and Bernoulli-Euler beam theories, including the effect of nonlocality and employing the Fourier sine series together with Stokes' transformation, systems of linear equations are obtained and solved using the coefficient matrices. The combined effects of elastic boundary conditions, elastic foundation, dispersion patterns and volume fractions of carbon nanotubes, and nonlocal parameter are examined by solving eigenvalue problems constructed with Fourier infinite series. Free vibration frequencies are calculated for carbon nanotube-reinforced nanobeams under different rigid or restrained boundary conditions, including Winkler-Pasternak type elastic foundation. A comprehensive parametric study is performed, focusing on various effects for the free vibrational response of the composite nanobeam reinforced with carbon nanotubes. It is concluded that adding a small amount of carbon nanotube material can reinforce the stiffness of the composite nanobeam, and its free vibration performance is significantly affected by the distribution patterns, elastic medium, and boundary conditions.

Monte Carlo simulations reveal distinct magnetic behaviors in honeycomb, kagome, and triangular nanolattices, crucial for magnetic material development. The honeycomb nanolattice shows the earliest magnetization decline, followed by the kagome and triangular nanolattices, due to differences in atomic arrangement and geometry. Increasing the linear coupling interaction (J), biquadratic coupling interaction (K), and external magnetic field raises the blocking temperature, while a higher crystal field (∣D∣) lowers it. These findings are pivotal for optimizing magnetic stability and behavior in applications like magnetic storage, sensors, and nanotechnologies.

The Hamiltonian of a four-sublattice simple cubic superlattice was solved by applying the linear spin-wave theory and the retarded Green's function technique. This study focused on the spin-wave resonance frequency, energy gap, sublattice magnetization, and quantum fluctuations of the system. The results show that the spin quantum number, interlayer (intralayer) exchange couplings, and intralayer anisotropy have a significant influence. In the ground state, the magnetizations of the sublattices are smaller than their spin quantum numbers, indicating the existence of quantum zero-point vibrations in the (anti)ferrimagnetic-(anti)ferrimagnetic bilayer system.

The scheelite-type CdMoO₄ nanopowders were prepared through calcination of an oxalate precursor in static air at 500 °C for 2h. The oxalate precursor was analyzed by Fourier transform infrared spectroscopy (FTIR) and thermal gravimetric analysis (TGA). The as-synthesized cadmium molybdate was characterized by Raman spectroscopy (RS), X-ray diffraction (XRD), Scanning electron microscopy (SEM), and Energy dispersive X-ray spectroscopy (EDX). Its catalytic activity was tested by the oxidation reaction of methylene blue (MB) dye in the presence of hydrogen peroxide. The obtained results showed that CdMoO₄ nanopowders have very high catalytic activity with a yield of 98 % during a period of 2h under alkaline conditions at pH 11.
