In this study, we present the experimental evidence demonstrating the utility of electrical double layer (EDL)-induced ion accumulation, using sodium (Na+) ion in water as a model substance, on a negatively charged nanostructured surface, specifically thermally grown silicon dioxide (SiO2). This novel approach, termed Ion Surface Accumulation (ISA), aims to enhance the performance of nanostructured porous silicon (PSi) interferometers in optical refractometric applications.

Ebook "Short-channel organic thin-film transistors: Fabrication, characterization, modeling and circuit demonstration" takes advantage of high-resolution silicon stencil masks to build air-stable complementary OTFTs using a low-temperature fabrication process. Plastic electronics based on organic thin-film transistors (OTFTs) pave the way for cheap, flexible and large-area products. Over the past few years, OTFTs have undergone remarkable advances in terms of reliability, performance and scale of integration.

In this paper, an equivalent circuit model of parallel power MOSFETs describing the dynamic current-sharing behaviors from the turn-off state to the conducting steady state has been studied. The equivalent circuit model represents the relationship between each power MOSFET’s gate voltage with respect to the sharing current. The performance of the equivalent circuit model is validated through a comparison of the sharing current with respect to the gate voltage curve obtained from the proposed model and that of the experiment.

In this work, the temperature dependence of the anharmonic X-ray absorption fine structure (XAFS) and thermodynamic properties of the crystalline silicon (c-Si) have been investigated. The thermodynamic parameters are derived from the influence of the absorbing and backscattering atoms of all their nearest neighbors in the crystalline lattice with thermal vibrations.

Paper "Investigating the structure and thermodynamic properties of silicene materials when cooling fast by molecular dynamics simulation" presents the results of two-dimensional silicene cooling studies by MD simulation with a sample of 6400 atoms. The Silicene model was run on Lammps software with a StillingerWeber interaction potential. Silicene after melting to 3500K, it is cooled at a rate of 1013 K/s to a temperature of 300K. Investigation of the dependence of energy on temperature shows a jump in the average total energy of molten silicene at the temperature T = 1965K.

In this work, a model is delivered, which highlights a simple mathematic relationship between the refractive index of an optical material and its transmittance spectrum measured by Fourier Transform Infrared Spectroscopy. Such model allows determining the refractive index of ceramics fabricated by hot-pressing of MgF2 nanoparticles. The reliability of this method has been verified on a silicon wafer taken as a reference (< 0.5%, discrepancy with data from literature on Si). Our approach can be applied to a variety of promising novel optical materials being developed.

In this work, the anharmonic extended X-ray absorption fine structure (EXAFS) oscillation of crystalline silicon (c-Si) is presented in terms of the Debye-Waller factor using the cumulant expansion approach up to the fourthorder. The first four EXAFS cumulant has been calculated based on the classical anharmonic correlated Einstein (ACE) model and suitable analysis procedure, in which thermodynamic parameters are derived from the anharmonic effective potential obtained using the first shell near-neighbor contribution approach.

he amorphous core dry-type cast-resin transformer is a type of energy- saving transformer, which the no-load losses in the amorphous metal is generally lower from 60% to 70 % than regular electrical steel (silicon steel). In this paper, the iron core and winding thermal of the dry-type transformer are simulated/analysed via a finite element method. The analysis of temperature distribution characteristics of iron core and winding in transformers is a quite important problem for researchers to show the hot-spot and the temperature rise highest point.

In Part I of this paper, the two-temperature homogenized model for the fully ceramic microencapsulated fuel, in which tristructural isotropic particles are randomly dispersed in a fine lattice stochastic structure, was discussed. In this model, the fuel-kernel and silicon carbide matrix temperatures are distinguished. Moreover, the obtained temperature profiles are more realistic than those obtained using other models. Using the temperature-dependent thermal conductivities of uranium nitride and the silicon carbide matrix, temperaturedependent homogenized parameters were obtained.
