Vibrational wave scattering in disordered ultra-thin film with integrated nanostructures

Sansabilla Bouchareb, Rachid Tigrine, Sabah Fetah

Article number: 20220135

Abstract

A theoretical model, the phase-field matching theory, has been used to investigate the localized states, their associated states, the local vibrational density of states, the coherent conductance, and the associated thermal conductivity of the perturbed ultra-thin film quasi-dimensional crystalline lattice. The defect disrupts the system’s translational symmetry in the perpendicular direction to it, which is axis Ox, and induces a localized state in its behavior that is not present in the bulk, scattering the incident elastic wave. The model was analyzed for three different cases of elastic parameters: softening, homogeneous, and hardening. The purpose is to investigate how the local dynamics can respond to changes in the microscopic environment in the perturbed domain. The analysis of the total phononic conductance spectra and the local vibrational densities states identifies distinguishing characteristics and demonstrates the sensor’s potential use in nondestroyed control.

Abstract

Perovskites are considered the most promising material for the latest generation of solar cells. However, due to the presence of lead in their composition, the development of non-toxic Perovskite cells has become an essential goal to enable their large-scale production. In this work, we have simulated, modeled and optimized the structure of a single solar cell that consists of a non-toxic cesium–tin–iodine CsSnI 3 Perovskite absorber with a low band gap energy value of 1.3 eV, between TiO 2 and PTAA materials as ETL and HTL layers, respectively. A simulation model describing the charge carrier processes and the effect of interface defect density is presented. Several structures based on alternative ETL and HTL materials are proposed. An optimal device structure is proposed based on the results obtained. An efficiency of 19.92% is obtained with V oc = 0.829 V, J sc = 30.68 mA/cm 2 and FF = 73.33% using SnO 2 and Spiro-OMeTAD as ETL and HTL materials. However, 29.22% is achieved using the optimal structure as the bottom cell in a tandem configuration.

Abstract

Seismological investigations are of a particular importance for the behavior of engineering structures and other structures of interest for the society under earthquake effects. This refers not only to the location of the structures themselves but also to their wider surrounding. In this context, it is important to determine the speed of seismic waves to define the possible location for the construction of secondary seismic stations. Also, determination of the speed of the seismic waves is very important to determine the compactness of the rock, where the seismic equipment is placed to increase the efficiency of monitoring the seismic activity.

Abstract

It is favorable to re-evaluate the seismic hazard for a given territory, since in the course of time new methods are developed and new data are gathered that can enable more sophisticated (physically sound) and reliable assessment of the seismic hazard. Therefore, it is mandatory to re-evaluate the seismic hazard for Kosovo, considering the seismic sources in Kosovo. The data of this article influence the reduction of seismic risk for the territory of Kosovo.

Abstract

In order to address the impact of the perforated parameters on the mechanical properties of the plate, the ultimate strength of hyper-ellipse flanged-perforated plates under uniaxial compression stress is numerically investigated in this article. The four edges of the flanged-perforated plate are only supported in the out-of-plane direction while the plate is exposed to uniaxial compressive loads. The impact of the cutout size, flange height, cutout position, rotation angle, and cutout form on the ultimate bearing capacity of the perforated plate with varied thicknesses is investigated and compared through a series of elasto-plastic buckling analyses using the ANSYS software. The structure’s stress and deformation analysis is then used to explain the results of the ultimate strength test. The flange efficiently raises the maximum bearing strength of the structure with cutouts. For the limit strength of thick plate, the cutout size, elliptical shape, cutout rotation angle, and cutout position have considerably more of an impact than they do on the maximum bearing capacity of thin plate. The findings can assist the structural layout of this sort of perforated plate, and the right cutout parameters should be chosen in accordance with the various performance specifications.

Abstract

The accessibility to rheological parameters for concrete is becoming more and more relevant. This is mainly related to the constantly emerging challenges, such as not only the development of high-strength concretes is progressing very fast but also the simulation of the flow behaviour is of high importance. The main problem, however, is that the rheological characterisation of fresh concrete is not possible via commercial rheometers. The so-called concrete rheometers provide valuable relative values for comparing different concretes, but they cannot measure absolute values. Therefore, we developed an adaptive coaxial concrete rheometer (ACCR) that allows the measurement of fresh concrete with particles up to d max = 5.5 mm {d}_{{\rm{\max }}}=5.5\hspace{.5em}{\rm{mm}} . The comparison of the ACCR with a commercial rheometer showed very good agreement for selected test materials (Newtonian fluid, shear thinning fluid, suspension, and yield stress fluid), so that self-compacting concrete was subsequently measured. Since these measurements showed a very high reproducibility, the rheological properties of the fresh concrete could be determined with high accuracy. The common flow models (Bingham (B), Herschel–Bulkley, modified Bingham (MB) models) were also tested for their applicability, with the Bingham and the modified Bingham model proving to be the best suitable ones.

Abstract

It is well known that sulfonamide derivatives, through exchange of different functional groups without modification of the –S(O) 2 N(H)– function, can exhibit a wide variety of pharmacological activities. In addition, some metal complexes of these ligands have been prepared to promote rapid healing of burns in humans and animals, for example, the complex of Zn( ii ) sulfadiazine. Their effectiveness does not depend solely on the slow release of the metal ion, but rather strongly on the nature of the material to which the metal is bound. Given the ability of sulfonamide derivatives to coordinate with metal atoms in different ways, considerable interest in the synthesis and structural aspects of new complexes has arisen. These results confirm that the significant chemical capacity of sulfonamides to act as ligands is based on the acidity of its –S(O) 2 N(H)– function, which gives a donor anionic ligand, allied to the presence of atoms vicinal to nitrogen, sulfur or oxygen of the heterocyclic ring, which provide the stereochemical requirements for the realization of complexes with monodentate ligand, chelating agent or bridging ligand, providing monomeric structures, dimeric arrangements and polymers. In addition, the aromatic amino group is responsible for the chemical versatility of the sulfonamides, since it can act as a coordination site, as well as a reactive site for chemical modifications of sulfonamide complexes with very interesting biological purposes. In the present work, the synthesis and structure of a novel sulfanilamide complex: nitro (4-aminobenzenesulfonamide) zirconium was presented. Characterization of the complex was performed by infrared spectroscopic, thermogravimetric and X-ray diffraction analysis.

Abstract

In this study, the feasibility of the trigeneration system, which is one of the on-site energy production methods, was determined for Kocaeli University Umuttepe Campus, exergy and energy analyses were made for each point of the system and exergy destruction in the lines was found. The key point of the gains, losses, and efficiency analyses in the lines are presented with engineering solutions and thermodynamic proofs. The seasonal mathematical models covering the whole of the feasibility of the trigeneration system were carried out and the energy and equilibrium equations of the entire system were established. In addition, energy and exergy analysis, 2nd law efficiency, coefficient of performance (COP), and thermal efficiency were calculated for all the systems. The seasonal numerical analyses of the system have been prepared so that it can work effectively in two different working disciplines separately for summer and winter seasons. Thanks to these numerical analyses that are mentioned, the seasonal exergic destructions of the system are found, seasonal working methods are shown, and working conditions and operating load values suitable for the current season are determined. In addition, in the light of the technical studies mentioned above, both the hourly energy capacities and hourly consumption values that the university will produce after trigeneration have been compared by performing separate mathematical models for summer and winter modes. Thus, it has been aimed to reduce the energy production costs by selling the excess energy to the mains. It is for this reason that it is aimed to reduce the energy production costs of the country, to reduce foreign dependency to meet energy demand, to present both a ready to apply feasibility report to investors and a ready to use design of a medium-sized power plant that will set an example of trigeneration studies in academic terms. In today’s practical applications, it is known that the system efficiency of trigeneration systems can be between 70 and 80%. In the light of the studies, 66% exergic efficiency in winter, thermal efficiency of 0.87411 with 2.05 MW thermal capacity, 63% exergic efficiency in summer, COP of 0.82 with 1.5 MW cooling capacity, and 2.02 MWe instantaneous electrical power was found in summer and winter. It was decided that the system could be a facility that is technically open to development and worth establishing in the light of the exergic and energetic analyses results obtained in this study and the exergic system efficiency comparisons made in the literature. In this study, attention was drawn to the importance of exergy and energy analyses in deciding the installation of a trigeneration system, and it was shown that exergic and energetic analyses played a key role in the verification of decision mechanisms. In order to give an idea for other studies in the literature, it is aimed to draw attention to the need to perform seasonal exergy and energy analyses of the designed or desired trigeneration systems.

Abstract

In order to investigate the dynamic response characteristics and damage mechanism of the tunnel lining at the tunnel portal in the bridge–tunnel overlapping section in soft rock strata, a physical model with the scale ratio of 1:50 was made based on the similarity theory for shaking table tests. The acceleration and strain results of the tunnel lining under EL Centro seismic waves with different acceleration peak values were studied. Test results show that most of the acceleration values have significant amplification effects compared to input seismic waves, which increased significantly with greater peak values and elevations. Tensile deformations appear along the longitudinal and the circumferential directions of the tunnel lining. The tunnel spandrel and tunnel vault are the maximum deformation parts, respectively, at the standard section and the enlarged section of the tunnel lining. Therefore, it is suggested that the longitudinal anti-tensile design of the tunnel lining at the tunnel portal in such sensitive environments should be strengthened. And the anti-seismic design standard and durability requirement of the standard section of the tunnel lining adjacent to the enlarged section should be improved, so as to meet the requirements for stress deformation and overall stability when subjected to severe earthquakes.

Abstract

Based on the collected soil property index test data of more than 2,500 groups of inland fluvial-lacustrine soft soil, the correlation of physical and mechanical parameters of this soft soil was systematically analyzed. The results show that the physical indexes of inland fluvial-lacustrine soft soil are close to that of marine soft soil, while its mechanical indexes are higher. However, the variation coefficient of its mechanical indexes is much larger than that of the physical indexes. In addition, it is found that the cone penetration parameters of this soft soil are significantly correlated with its physical and mechanical indexes by establishing a series of empirical relationships between the static point resistance and the natural unit weight, the liquidity index, the quick shear cohesion, and vane shear strength. On the basis of the previous research results, the disturbance strength of inland fluvial-lacustrine soft soil can be converted into in situ strength by deriving the theoretical formula between the vane shear strength and the disturbance degree. The calculation process of the above conversion relation is explained in detail through an engineering case, which indicates that the theoretical formulas have good applicability for inland fluvial-lacustrine soft soil.

Article number: 20220143

Abstract

The purpose of this article is to provide an effective approach to evaluate slope stability in real-time in a reservoir area, which is significant for carrying out risk management for landslide disaster prevention in various engineering practices. A comprehensive idea for stability estimation of bank slope under the influence of rainfall or the reservoir water level is presented in this work. Slope stability analysis and back analysis of soil parameters are both included based on numerical simulation. The mechanical parameters of the bank slope were first back-analyzed using particle swarm optimization (PSO), and real-time stability analysis with high accuracy and efficiency was then established based on multiple continuously monitored displacements. Two case studies were carried out in this study. The results show that (1) based on the real-time monitored displacement and numerical simulation, the mechanical parameters of the slope can be reasonably retrieved through PSO; and (2) based on the inverse mechanical parameters, the safety factors of the slope can be numerically obtained, so that the real-time estimation of slope stability can be realized.
