Virtual undergraduate chemical engineering labs based on density functional theory calculations
Authors: Altarawneh Mohammednoor 
Published: September 2023

Abstract
Offering virtual laboratories to chemical engineering students is likely to extend beyond the COVID-19 era. Thus, there is a need to develop more simulation-based tasks in a wide blend of subjects, spanning thermodynamics, chemical reactions, and unit operations. Molecular and material modeling based on density functional theory (DFT) calculations provides limitless opportunities to train students on how to obtain thermokinetic values that are typically measured experimentally. Through a series of illustrative cases, this contribution provides detailed procedures pertinent to calculating reaction rate constants, standard enthalpies of reactions, redox potentials, equilibrium reaction constants, and surface-assisted mechanisms. We hope that DFT-operated virtual labs will assist students in attaining learning outcomes and promote their self-learning in the above-mentioned subjects. From a broader prospective, the presented case studies are expected to encourage students to appreciate the practical applications of DFT, not only in the academic but also in the industrial domains.
Passive Sentences and Abstract Agents in German School Books
Authors: Olthoff Sarah 
Published: September 2023

Abstract
Although the competent handling with passive is acquired before school entrance, its comprehension is considered to be challenging in school books. According to a corpus linguistic analysis, passive is more frequent in school books than in texts from leisure contexts. Moreover, the agent differs semantically depending on context: Human agents appear predominantly in all contexts, but the proportion of abstract systemic agents are significantly higher in school books for biology and chemistry than in school books for history or in texts from leisure contexts. Furthermore, a survey shows that students do not perceive the general use of passive as challenging, but those sentences with abstract systemic agents are assessed as more challenging than comparable sentences with human agents. This leads to the assumption that challenges in reception of school books arise neither only from grammatical structure nor from global linguistic functions. Semantical and functional differences from specific constructions are fundamental to locate potential language-based challenges in school books. Consequently, the joint reflection of concrete formal and functional aspects should be considered in the development of diagnostic instruments as well as in the operationalisation of the language of schooling. Furthermore, cross-linguistic comparisons can sensitise for conspicuous use of structures and support a language-sensitive teaching in both languages.

Published: September 2023

Abstract
Green synthesis of zinc oxide (ZnO) nanoparticles (NPs) using various plant extracts as reducing and capping agents has gained attention in recent research. The green synthesis of ZnO NPs offers several advantages such as being simple, eco-friendly, safe, cost-effective, and reproducible approach with high stability. Hence, this article provides an overview of zinc metal and ZnO compounds, and traditional chemical and physical synthesis of ZnO NPs with primary focuses on the green synthesis of ZnO NPs. This study discusses various plant extracts used and the proposed mechanisms in the green synthesis of ZnO NPs. Additionally, it explores the cytotoxic mechanisms of the green-synthesized ZnO NPs and addresses the various biomedical applications of ZnO NPs, including antibacterial, anticancer, antidiabetic, antioxidant, antifungal, antiviral, antiparasitic, anti-inflammatory, and wound healing. Moreover, the review critically discusses the toxicity of ZnO NPs and emphasizes the need for more toxicological studies to ensure the safety and facilitate the risk assessments and risk management of ZnO NPs. Furthermore, this review underlines the challenges associated with the translation process of ZnO NPs from bench to market, including the complex and time-consuming regulatory approval process for ZnO NPs, which requires a multidisciplinary approach involving scientists, regulators, and manufacturers.
Recent developments in terahertz quantum cascade lasers for practical applications
Authors: Gao Liang , Feng Chao , Zhao Xian 
Published: September 2023

Abstract
Terahertz (THz) quantum cascade laser (QCL) is an electrically pumped unipolar photonic device in which light emission takes place due to electronic transitions between subbands formed by multiple strongly coupled quantum wells. THz QCL is arguably the most promising solid-state source to realize various THz applications, such as high-resolution spectroscopy, real-time imaging, chemical and biological sensing, and high-speed wireless communication. To date, THz QCLs have covered emitting frequency from 1.2 to 5.4 THz when operating without the assistance of an external magnetic field. The highest output power is in hundreds milliwatt and watt levels continuous-mode and pulsed-mode operations, respectively. THz QCL-based local oscillators have been implemented in astronomy for the identification of atoms and ions. However, there are also limitations, including under room-temperature operation, large divergent beam, narrow single-mode frequency tuning range, incomplete polarization control, and narrow-range frequency comb operation that hinder the widespread applications of THz QCLs. Continuous efforts have been made to improve those THz QCL properties in order to satisfy the requirements of different THz applications. This report will review the key output characteristic developments of THz QCLs in the past few years, which aim to speed up THz QCLs toward practical applications.
Connectivity by the Frontal Aslant Tract (FAT) Explains Local Functional Specialization of the Superior and Inferior Frontal Gyri in Humans When Choosing Predictive over Reactive Strategies: A Tractography-Guided TMS Study

Published: September 2023

Predictive and reactive behaviors represent two mutually exclusive strategies in a sensorimotor task. Predictive behavior consists in internally estimating timing and features of a target stimulus and relies on a cortical medial frontal system [superior frontal gyrus (SFG)]. Reactive behavior consists in waiting for actual perception of the target stimulus and relies on the lateral frontal cortex [inferior frontal gyrus (IFG)]. We investigated whether SFG-IFG connections by the frontal aslant tract (FAT) can mediate predictive/reactive interactions. In 19 healthy human volunteers, we applied online transcranial magnetic stimulation (TMS) to six spots along the medial and lateral terminations of the FAT, during the set period of a delayed reaction task. Such scenario can be solved using either predictive or reactive strategies. TMS increased the propensity toward reactive behavior if applied to a specific portion of the IFG and increased predictive behavior when applied to a specific SFG spot. The two active spots in the SFG and IFG were directly connected by a sub-bundle of FAT fibers as indicated by diffusion-weighted imaging (DWI) tractography. Since FAT connectivity identifies two distant cortical nodes with opposite functions, we propose that the FAT mediates mutually inhibitory interactions between SFG and IFG to implement a “winner takes all” decisional process. We hypothesize such role of the FAT to be domain-general, whenever competition occurs between internal predictive and external reactive behaviors. Finally, we also show that anatomic connectivity is a powerful factor to explain and predict the spatial distribution of brain stimulation effects.SIGNIFICANCE STATEMENTWe interact with sensory cues adopting two main mutually-exclusive strategies: (1) trying to anticipate the occurrence of the cue or (2) waiting for the GO-signal to be manifest and react to it. Here, we showed, by using noninvasive brain stimulation [transcranial magnetic stimulation (TMS)], that two specific cortical regions in the superior frontal gyrus (SFG) and the inferior frontal gyrus (IFG) have opposite roles in facilitating a predictive or a reactive strategy. Importantly these two very distant regions but with highly interconnected functions are specifically connected by a small white matter bundle, which mediates the direct competition and exclusiveness between predictive and reactive strategies. More generally, implementing anatomic connectivity in TMS studies strongly reduces spatial noise.

AbstractA combination of roll-to-roll coating and nanoimprinting technique is proposed for large-scale fabrication of porous nanosheets. Poly (d,l-lactic acid) (PLA) in 2-methoxy-1-methylethyl-acetate is roll-to-roll coated on polypropylene substrate to obtain nanosheets with thickness above ca. 95 nm. Roller nanoimprinting with a nickel mold is applied to fabricate pores on nanosheets with diameter of ca. 1.2 μm. The imprinted PLA nanosheets with thickness above ca. 129 nm can be directly peeled from the substrate using a polyester adhesive tape frame with open circle of 30 mm. This method shows promising potential for achieving continuous production of porous nanosheets to facilitate their application.

En este estudio se exponen las técnicas de inferencia causal utilizadas para descubrir los factores subyacentes que contribuyen a los retrasos prolongados en la aprobación de cursos de primer año que se observan en la Carrera de Ingeniería Civil de la Facultad de Ciencias Exactas y Tecnología (FACET). de la Universidad Nacional de Tucumán (UNT), Argentina. Hasta el año 2019, los estudiantes tardan un promedio de 5 años en aprobar sus asignaturas del primer año. Determinar las causas de ese retraso fue el motivo de la presente investigación.

Nuestro análisis se basó en la utilización del marco de trabajo DoWhy (Blöbaum et al., 2022; Sharma y Kiciman, 2020) y Causal Discovery Toollbox (CDT) (Kalainathan et al., 2020), herramientas diseñadas para la inferencia causal. Nuestro objetivo era desentrañar la red de variables que influyen en los tiempos de aprobación de los cursos. Los hallazgos del estudio iluminan un factor causal fundamental que conduce a un aumento estadísticamente significativo en la duración de la aprobación. Específicamente, se reveló que la estructura regulatoria del programa académico y los métodos de evaluación empleados juegan un papel sustancial. En particular, la acumulación de materias regulares que aún no han sido aprobadas mediante un examen final surgió como un determinante clave.
Este conocimiento tiene el potencial de guiar intervenciones específicas, mejorando tanto las tasas de éxito de los estudiantes como la eficacia general del sistema educativo.

Nowadays, the state level has set the task of forming a systematic approach to secondary resources management that were obtained from production waste, as well as increasing the efficiency of resource useage throughout the production life cycle. This is evidenced by the initiation and implementation of the sectoral program «Usage of secondary resources and secondary raw materials from waste in industrial production», supervised by the Ministry of Industry and Trade of the Russian Federation since November 2022, Decree of the President of the Russian Federation of November 4, 2020 No. 666 «On Reducing Greenhouse Gas Emissions», Strategy «Socio-Economic Development of the Russian Federation with Low Greenhouse Gas Emissions by 2050» approved by order of the Government of the Russian Federation of October 29, 2021 No. 3052-r and Federal Law of 02.07.2021 No. 296-FZ «On Limiting Greenhouse Gas Emissions» (entered into force 30.12.2021).
To achieve economic, social and environmental sustainability, it is necessary to interact between enterprises, universities and authorities in order to stimulates the application of the principles of circular economics. This article discusses the problem of utilization and use of associated petroleum gas, as well as analyzes the possibilities of applying the concept of industrial symbiosis both to reduce the produced resources and minimize the loss of materials during use. The relevance of this topic is justified by an increase in the volume of associated petroleum gas (APG) production and, accordingly, the damage caused to the environment due to its combustion. In addition, insufficient financial investment hinders the successful development of innovative economic schemes such as industrial symbiosis.
The methods of APG disposal and processing used at present were analyzed, the negative consequences of combustion, sanctions imposed by the state and restrictions on their application were investigated. According to the authors, an important problem is the lack of new technologies, as well as the low level of their technological readiness, which leads to the use of most APG as energy resources instead of its processing. The study briefly discusses the main methods of processing associated petroleum gas, their advantages and disadvantages, as well as possible recommended areas of APG use.
The effectiveness and feasibility of introducing the concept of industrial symbiosis in the oil industry is justified. As a result of the study, the authors of this article proposed the most optimal option for processing and further use of the obtained components, the probability and reality of the implementation of the described processing method is also described.
METHODOLOGICAL ASPECTS OF THE STUDY OF THE RATE CONSTANT OF THE REACTION OF HYDROCHLORIC ACID WITH CARBONATE FORMATION ROCK

Published: September 2023

Hydrochloric acid treatments are most widely used to intensify oil production from carbonate reservoirs. But despite a wealth of experience in the use of hydrochloric acid treatments, the results of treatments often do not reach the planned values of oil production growth. Efficiency of acid exposure depends on the depth of penetration of the hydrochloric acid solution into the thickness of the productive reservoir, which, in turn, is conditioned by the degree of reactive activity of the acid composition. It is important to achieve the creation of filtration channels in the zone remote from the borehole, which will lead to an improvement in the filtration characteristics of the bottomhole formation zone to the proper extent. Therefore, in order to achieve the best result when planning acid exposure, it is important to consider the geological and physical properties of the object to be treated and select the appropriate formulation of the acid composition.
The reaction rate constant is a parameter that allows you to take into account the compatibility of the acid composition and the geological and physical conditions of the productive reservoir. This parameter characterizes the rate of reaction between substances. However, a generally accepted method for studying the kinetic parameters of the reaction of acid compositions with carbonate formation rock has not yet been developed, which leads to low reproducibility of experimental results. The purpose of the research presented in the article is to develop a methodology for studying the kinetics of the reaction of hydrochloric acid with carbonate rock and to create a unified approach to determining the reaction rate constant, characterized by the greatest reproducibility of the results. The experimental part of the work was carried out in several stages, including the preparation of core material, the preparation of hydrochloric acid solution and its thermostating, and the further conducting of four series of studies at the PIK-OSG volumetric setup to determine the optimal acid-rock ratio, identify the optimal weight of the core material and establish the optimal coarseness of its grinding.
The obtained results of experiments on the study of methodological aspects of the study of the rate constant of the reaction of hydrochloric acid with carbonate rock showed that the experiments should be conducted in conditions of an excess of rock relative to acid, in this case the mass of the core sample and the coarseness of the grinding of the core material will not affect the error in determining the reaction rate constant.
