A SIMPLIFIED SCHEME FOR DEVELOPING THE TOLERANCE FACTORS FOR SOME CRYSTAL STRUCTURES
Authors: Sidey V.I.
Published: July 2024

The tolerance factor, developed and proposed by Goldschmidt to estimate the stability limits of the cubic perovskite ABX3 structural type for a given chemical composition, has been widely used in solid state chemistry and physics as well as in the related fields of science. Based on the idealized cubic perovskite structure and the ionic radii of the constituents r(A), r(B), and r(X), Goldschmidt derived the formula for the tolerance factor as the ratio between the sums of the ionic radii of cations and anions, {[r(A) + r(X)] / (√2 × [r(B) + r(X)])}, which is equal to 1 in the ideal perovskite structures. From the obtained value of the tolerance factor, it is possible to make reliable predictions about the possibility of the existence of a cubic perovskite phase of a given chemical composition.
The convenience of using the Goldschmidt tolerance factor in the studies of perovskite structures prompted some researchers to begin searching for similar indicators for representatives of other scientifically and technologically important structural families. However, despite the mathematical correctness of the final formulas of the alternative tolerance factors, the derivation of these formulas in a number of works seems to be unnecessarily complicated.
In the present work, a simplified approach has been proposed for developing the alternative tolerance factors from the geometric characteristics of regular coordination polyhedra – namely, from the relationships between the edges and the circumscribed sphere radii of such polyhedra. The proposed approach can be used to derive the tolerance factors formulas for any crystal structures containing regular or nearly regular coordination polyhedra of different types with the same edge lengths.

The present work is aimed to the study of the physical characteristics of single crystal samples of Ag7+x(P1-xGex)S6 solid solutions (x = 0, 0.1, 0.25, 0.33, 0.5, 0.75, 1). Single crystals of Ag7+x(P1-xGex)S6 solid solutions were grown by the method of directional crystallization from the melt. Specially prepared samples of the grown single crystals of Ag7+x(P1-xGex)S6 solid solutions were studied by spectral ellipsometry method. The spectral dependences of the refractive index are characterized by nonlinearity with a maximum in the spectral range ~645-820 nm. It has been found that cationic substitution in P5+→Ge4+ solid solutions lead to a monotonic nonlinear increase in the refractive index n from 2.58 (x = 0) to 2.75 (x = 1). The obtained values of the refractive index were used to describe the optical parameters using the Wemple-DiDomenico equation. It was found that parameters of Wemple-DiDomenico model – the energy of a single oscillator, the dispersion energy are characterized by a tendency to monotonous decrease in the process of heterovalent cationic P5+→Ge4+ substitution. The established values of the optical band gap Eg suggest that single crystal samples of Ag7+x(P1-xGex)S6 solid solutions can be used as promising materials for solar energy.

idea de América Latina: fundamentos políticos e intelectuales de un concepto en permanente transformación
Authors: Paikin Damián
Published: July 2024

La idea de América Latina, como marca identitaria y campo de análisis, ha ido mutando a lo largo de la historia construyendo diferentes configuraciones tanto simbólicas como territoriales. En cada momento histórico, distintos estudios reflexionaron sobre su utilidad. En ese marco, la pregunta central de este trabajo es definir qué elementos perduran para que dicho nombre siga siendo de vital trascendencia en la actual configuración global y regional. Como hipótesis se plantea que, en tanto definición política antes que territorial o lingüística, su persistencia continuará mientras los principales ejes de las identidades nacionales se estructuren en el par autonomía-desarrollo, es decir, desde una posición periférica frente al poder global.

Authors: Noviarni Intan , Ningsih Syukrya
Published: July 2024

The study primarily focused on analyzing the prospective utilization of waste biomass, particularly those possessing antioxidant properties, for soap formulation. Antioxidants serve as radical scavengers, protecting against oxidative damage in both soap and human skin. This research aims to assess solid bath soap's efficacy and antioxidant potential when combined with Gerga orange peel (Citrus nobilis L. var RGL) extract. The quality of the bath soap was evaluated based on the Indonesian National Standard (INS) 3532:2021. The antioxidant activity of the soap was determined using the DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging technique. The solid bath soap formulations underwent rigorous quality testing, and the findings indicated that they exceeded the standards set by INS 3532:2021 for solid bath soap quality. These formulations demonstrated superior performance in various parameters, including pH levels, moisture content, free fatty acids, free alkali, solubility in alcohol, and foaming capabilities. The antioxidant activity of each soap formulation was quantified by its IC50 value. The results showed that the level of antioxidant activity in the solid bath soap increased proportionally with the quantity of Gerga orange peel extract used. Overall, the findings suggest a favorable potential for utilizing Gerga orange peel extract as a cost-effective and feasible natural antioxidant component in soap production.

Authors: Baari Muhamad Jalil , Alif Alfiah , Kurniawan Muhammad Akbar S , Finarisnawati Finarisnawati
Published: July 2024

Corrosion is a severe problem in the petroleum industry. The use of corrosion inhibitors is an effort to reduce the corrosion rate on metal materials. This study used the computational chemistry approach to investigate the corrosion inhibition performances of 4,5-diphenyl imidazole and its derivatives with additional substituents, for instance, electron acceptors and electron donors. Geometry optimizations and calculations of molecular frontier orbital energies were conducted using density functional theory (DFT) in the aqueous phase. These frontier orbital energy values were used to determine other reactivity and stability parameters, such as band gap energy, electron affinity, ionization potential, chemical hardness, chemical softness, number of electron transfers, chemical potential, nucleophilicity, electrophilicity, electronegativity, back donation energy, and interaction energy. Electrostatic potential, Mulliken atomic charge, and theoretical inhibition efficiency of 4,5-diphenyl imidazole derivatives were also determined. Generally, the presence of electron donor substituents theoretically increases corrosion inhibitors. The 4,5-diphenyl imidazole with –NH2 substituent is a better derivative than others based on several reactivity and stability parameters due to adding adsorption centers. Therefore, it can increase the performance of 4,5-diphenyl imidazole as a corrosion inhibitor. The adsorption behaviors of 4,5-diphenyl imidazole and its derivatives on Fe(100) surfaces were investigated using molecular dynamics simulation. The binding energies of three types of inhibitors on the Fe surface of studied inhibitors followed the order: D–NH2 > 4,5-diphenyl imidazole (D) > D–NO2. This ranking obtained is consistent with the theoretical inhibition efficiency.

Pada keluwesan, kebanyakan siswa menunjukkan tingkat kreativitas yang baik, sementara pada orisinalitas dan elaborasi, siswa menunjukkan tingkat kreativitas yang sangat tinggi. Keterkaitan dari penelitian ini adalah pentingnya diferensiasi pembelajaran untuk menyesuaikan tingkat kreativitas siswa. Guru dapat mengembangkan strategi pembelajaran yang lebih sesuai dengan potensi kreatif masing-masing siswa, termasuk penggunaan metode pengajaran yang memperkenalkan keluwesan, penemuan ide orisinal, dan pengembangan kemampuan elaborasi. Sistem penilaian berbasis proyek juga dapat terus diperbaiki untuk mengukur aspek-aspek berpikir kreatif secara lebih komprehensif. Penelitian ini diharapkan dapat memberikan sumbangan bagi pemahaman tentang kreativitas siswa di tingkat sekolah menengah atas dan membuka pintu bagi penelitian lebih lanjut dalam konteks berpikir kreatif.
Effect of variable thermal conductivity in semiconducting medium underlying an elastic half-space
Authors: Ailawalia Praveen , Priyanka
Published: July 2024

The aim of the present work is to discuss the effect of varying thermal conductivity in a semiconducting medium under photothermal theory. An infinite elastic half-space is overlying the infinite semiconducting medium, and a constant me-chanical force is applied along the interface. The normal mode analysis method is applied to find the analytic components of displacement, stress, carrier density and temperature distribution. It was found that all physical quantities are affected by variable thermal conductivity. The novelty of the paper lies in the fact that no such a problem of variable thermal conductivity has been discussed by any researcher so far.
Flame stabilization and combustion enhancement in a scramjet combustor by varying strut injection angles

Published: July 2024

The present study explores the characteristics of reacting flow in a scramjet combustor with struts, focusing particularly on implementing different injection strategies. A three-dimensional DLR scramjet combustor is utilised to assess the impact on the system, incorporating multiple injections and varying injection angles on the triangular wedge. The analysis considers three injectors with parallel, upward and downward injections at angles of 15° and 30°. The numerical investigation is con-ducted under a constant total pressure of 7.82 bar, a temperature of 340 K, and an airspeed of Mach 2 at the inlet. The results highlight the significance of injector location and shape in promoting flame stabilization. Furthermore, injection angles play a crucial role in mitigating shockwave intensity. The numerical analysis involves a steady-state Reynolds-averaged Navier-Stokes equation with the shear stress transport k–ω turbulence model. The obtained results were analyzed by examining the critical variables such as Mach number, static pressure and combustion efficiency across the combustor. Based on the com-putational results, injecting fuel upward not only increases the overall pressure loss but also enhances the subsonic regime downstream of the strut, which leads to better mixing and combustion efficiencies. This is primarily due to shockwave generation from the edges of the strut and the interactions with the fuel stream shear layers.
Influence of wall temperature on condensation rate in duct flow of humid air: a comprehensive computational study
Authors: Bobrowski Jakub , Gutkowski Artur
Published: July 2024

In engineering phase-change phenomena are found in a multitude of applications, ranging from refrigeration and air con-ditioning to steam turbines and petroleum refining. This study investigates the flow of moist air in a circular duct where water vapour condenses in contact with the cold wall of the duct. The investigation delves into the relationship between the condensation mass transfer rate, the heat transfer between the bulk flow and the wall, and the temperature of the wall. The volume of fluid model coupled with the Lee evaporation-condensation model was employed. Five simulations were carried out, involving different wall temperatures while maintaining the same inlet conditions. Condensation was more pronounced at lower wall temperatures, which aligns with the expectations. The heat transfer between the bulk flow and the wall decreased with the decreasing temperature difference. Interestingly, the findings revealed that the surface heat transfer coefficient increased as the wall temperature approached the temperature of the bulk flow. The success of the study suggests potential applications in optimising thermal management systems, with implications for industries where accurate predictions of moisture behaviour and heat transfer are crucial.
Exergetic performance coefficient analysis of direct methanol fuel cell

Published: July 2024

In order to improve the output performance of direct methanol fuel cell, the finite-time thermodynamic model of direct methanol fuel cell is developed in this paper. Then, mathematical expressions for energy efficiency, power density, exergy efficiency and exergy coefficient of performance are derived. In addition, the effects of operating temperature, inlet pres-sure and membrane thickness on the performance of direct methanol fuel cells are considered. The results show that the exergetic performance coefficient not only considers the exergy loss rate to minimize the loss, but also the power density of the direct methanol fuel cell to maximize its power density and improve its efficiency. Therefore, the exergetic perfor-mance coefficient is a better performance criterion than conventional power and efficiency. In addition, increasing the inlet pressure and decreasing the membrane thickness can significantly improve the exergetic performance coefficient and en-ergy efficiency.

Preparation of Nano Membranes with Triethylenetetramine Dihydrochloride (TETA-DH) and Multiwalled Carbon Nanotubes (MWCNT) for Seawater Desalination
Authors: Alghamdi Ahmed
Published: July 2024

Seawater Desalination uses hydrophobic membranes. Many techniques have been developed to improve membrane hydrophobicity by depositing particles on the membrane surface. In this study, a nanocomposite membrane utilizing Triethylenetetramine (TETA) is suggested. The membrane incorporates Multiwalled Carbon Nanotubes (MWCNT) in conjunction with Triethylenetetramine Dihydrochloride (TETA-DH). In water bath, different percentages of TETA-DH films are formed. Electro-spin fabrication of MWCNTs using TETA-DH yields smooth, low-pore membranes. Membranes and their characteristics are identified by contact angle, layer thickness, and conductivity measurements. Membrane performance is examined for heat flux and salt rejection. Compared to commercial membranes, the proposed membrane exhibits superior antifouling and anti-wetting features. The membrane exhibited permeation and rejection ratio of 46 Kg m2 h−1 and 99.99% respectively which is superior as compared with other membranes. The hydrophilic Surface Modifying Macromolecules percentage (LSMM%) is evaluated because it depends on average pore size, hydrophobicity, surface porosity, and shape. The tests demonstrate the excellent performance of the proposed membrane for controlling membrane fouling.
