Cation-π Interactions Involving Graphynes: An Intermolecular Force Field Formulation Featuring Ion-Induced Dipole Effects
Authors: Kottayil Akhil , Sangeetha Prakash Medha , Swathi Rotti Srinivasamurthy
Published: November 2024

Over the past few years, graphynes (GYs), one of the latest families of carbon allotropes, have been investigated as promising materials for various applications, including lithium-ion batteries. Developing analytic potentials for describing potential energy surfaces underlying cation-π interactions is a challenging task for large-scale simulations involving carbon-based materials. This study aimed to develop effective analytic models to overcome computational challenges in accurately capturing cation-π interactions between alkali metal ions (Li+, Na+, K+) and GYs, which are crucial for ion storage and transport within nanoporous GY frameworks. The high computational demands of ab initio methods for such large systems make analytic modeling increasingly essential. The absence of reliable analytic potentials and parameters needs to be urgently addressed. Here, we report that the commonly used 12-6 Lennard-Jones (LJ) potential combined with electrostatics (EL) is insufficient for representing cation-π interactions, as it fails to capture the ion-induced dipole effects that are crucial for the problem in hand. To address this, we propose modified 12-4 LJ + EL and improved Lennard-Jones (ILJ) potentials, which better capture the necessary short-range repulsions and long-range attractions. We developed and validated parameter sets based on interaction energy curves from density functional theory (DFT), enabling a reasonably accurate modeling of cation permeation and surface dynamics on GY sheets. This work not only advances the understanding of cation-π interactions in GYs but also introduces computationally efficient models that support the design of GYs for next-generation energy storage applications.

Authors: Kang Hyotaik , Brack Enzo , Gioffrè Domenico , Yakimov Alexander , Copéret Christophe , Li Chao-Jun
Published: November 2024

Renewable liquid fuels are expected to play a crucial role in transitioning to a more sustainable future. Their synthesis via the hydrogenation of CO2 using solar energy emerges as a promising technology, that combines both the use of a renewable primary energy source and the (re)utilization of a major greenhouse gas. In this context, GaN has attracted a lot of attention in harnessing solar energy to drive chemical transformations. In this work we study GaN by 1H solid-state NMR spectroscopy, revealing the presence of terminal Ga-OH, bridging Ga–NH–Ga as well as Ga–OH–Ga surface functional groups and combinations thereof. With this knowledge in hand, we make use of surface organometallic chemistry (SOMC) to prepare a Pt/GaN catalyst with highly dispersed Pt nanoparticles on GaN. Under photothermal conditions using visible light (>320 nm), the synthesized Pt/GaN promotes the hydrogenation of CO2 to C2+ products such as acetone, EtOH, iPrOH, and acetic acid in a batch reactor at 60 °C and 1 bar of pressure, while the pristine GaN counterpart only produces minor amounts of MeOH and acetone. Furthermore, a recycling test was performed to showcase the stability of the catalyst over multiple batch reaction cycles.
Cooperative CO2 activation involving a mononuclear aluminum(II) intermediate
Authors: Singh Roushan , Quirion Kevin , Telser Joshua , Ess Daniel , Mankad Neal
Published: November 2024

An important aspect of sustainable chemistry research is the discovery of novel chemical mechanisms by which otherwise inert molecules become activated toward useful transformations by earth’s most abundant elements. Compounds involving the most abundant metal on earth, aluminum, most commonly involve AlIII ions due to their noble gas electronic configurations. Although compounds with AlI ions have also been studied, the chemistry of AlII ions is nearly unknown and may contain undiscovered reaction manifolds. Here, we report the CO2 activation chemistry of an AlII complex supported by a chelating, dianionic ligand and investigate the electronic structure details and reaction mechanisms required to access this reactivity. We found that a heterobinuclear complex, (NON)Al- FeCp(CO)2 (1), undergoes reversible Al-Fe bond homolysis at ambient conditions to reveal the [(NON)Al]·/[CpFe(CO)2]· radical pair in situ. The presence of predominantly Al-centered spin density (i.e., an AlII ion) within this radical pair was established using experiments with radical scavengers as well as electronic structure calculations. Exposure of 1 to CO2 atmosphere resulted in insertion of CO2 into the Al-Fe bond. This net 2-electron CO2 reduction process was computationally modeled using quantum chemical calculations and direct dynamics simulations, revealing that reduction involves two 1-electron steps and, thus, depends on stabilization of high-energy [CO2]· - by coordination to aluminum. This mechanism for CO2 activation is unexpected given the canonical predisposition of CO2 for multi-electron reduction processes and demonstrates the possibility of discovering new reaction profiles of earth- abundant elements in unusual oxidation states.

Authors: Angelov Plamen , Mollova-Sapundzhieva Yordanka
Published: November 2024

Anilides of 3-oxo-4-phenylaminobutyric acid with Troc or COOEt protection at the phenylamino group undergo competing cyclisation processes in neat polyphosphoric acid at 80 oC. Depending on the protecting group and the duration of the process, three main products in different ratios are formed. Along with the quinolin-2-ones, resulting from the classic Knorr-cyclisation, also an indole derivative and a spirocyclic product have been obtained from the COOEt-protected substrate. It has been demonstrated that the obtained indole derivative is capable of further dearomative spirocyclisation under the studied conditions.

Authors: Ying Yike , Tiemann Ruediger
Published: November 2024

As a key part of 21st-century skills, collaborative problem-solving (CPS) skills have been recognized as critical to both academic achievement and professional success. This paper explores the multifaceted influences on CPS skills among ninth-grade students in Germany and tenth-grade students in China within the context of chemistry education. Methodologically, a chemical assessment tool, CPS-C, was developed based on the CPS framework of PISA 2015, and various factors including cognitive ability, prior knowledge, motivation, mental load, stress, and CPS were measured. Results revealed significant differences between German and Chinese students across these factors, highlighting cultural and educational difference. Structural equation modeling (SEM) analysis demonstrated the intricate relationships between these factors and CPS performance, underscoring the importance of prior knowledge, cognitive ability, and motivation in enhancing CPS skills while revealing the detrimental effects of stress on performance. Additionally, CPS skills in chemistry exhibited positive correlations with academic performance in Biology, Physics, and Mathematics, indicating the transferability of CPS skills across disciplines. Overall, this study contributes to our understanding of CPS in diverse cultural and educational contexts, offering insights for educators and policymakers to design effective instructional strategies for fostering CPS skills in chemistry education.

Authors: Aribowo Widi , Abualigah Laith , Oliva Diego , Mzili Toufik , Sabo Aliyu , A. Shehadeh Hisham
Published: November 2024

This paper presents a Proportional-Integral-Derivative (PID) parameter optimization method for direct current (dc) motors. The method utilizes a metaheuristic technique known as Frilled Lizard Optimization (FLO), which is inspired by natural processes. FLO draws inspiration from the lizard's hunting method of employing a sit-and-wait approach with great patience. The method is divided into two distinct phases: the exploration phase, which simulates a swift predator attack by a lizard, and the exploitation phase, which imitates the lizard's return to the treetop after feeding. This study confirms the effectiveness of FLO by conducting performance tests on the CEC2017 benchmark function and a DC motor. Through the simulations conducted on the CEC2017 benchmark function, it has been determined that FLO has superior exploration and exploitation capabilities. When testing a DC motor, it was discovered that the PID-FLO approach is effective in reducing overshoot and achieving optimal performance

Authors: Nawawi Akhmad , Hermawan Aditya , Wardani Ayusta
Published: November 2024

This study examines the use of Yagi antennas to extend the LoRa SX1278 transceiver's range, focusing on enhancing communication distance and reducing signal loss. LoRa, a low-power wireless technology, enables long-distance transmission ideal for sensor data, reaching up to 15 km in rural areas and 1-5 km in urban environments. By adjusting impedance, the Yagi antenna improves LoRa signal range and quality by focusing transmission directionally, reducing interference. The test results show that the yagi antenna has better coverage and signal strength than the spring antenna. Testing horizontal conditions with 3 different locations shows that antenna design greatly affects the transceiver of data. The Yagi antenna with modified impedance has the ability to transmit the farthest distance of 6250 meters. Horizontal testing with a fairly short distance is not too significant a difference in the rssi value of the two antennas, but in terms of reception category, the spring antenna is still not good. Test results show that the Yagi antenna significantly outperforms the spring antenna, maintaining better signal strength at longer distances due to its effective electromagnetic energy focus.

La investigación se centró en la evaluación del contenido de hierro (Fe2+) en 51 muestras de fideos de diversas formas y precios, correspondientes a 20 marcas comercializadas en Ecuador. Se empleó el método AOAC 944.02 “Hierro en harina” por espectrofotometría, el cual fue validado en este estudio para asegurar su aplicabilidad en la determinación de hierro en fideos. Mediante análisis estadístico, se determinó que las diferentes formas y gamas de precios de los fideos no presentan una significancia estadística sobre el contenido de hierro. Sin embargo, existe una diferencia significativa en el contenido de hierro (p<0.005) entre fideos de diferentes orígenes (ecuatorianos, peruanos e italianos). Para poder establecer una comparación en el contenido de hierro se usó el rango de 37-73 mg de fumarato ferroso/ kg establecido en el Reglamento Ecuatoriano de fortificación y enriquecimiento de la harina de trigo. De esa manera se determinó que los fideos comercializados en Ecuador aportan aproximadamente de 4 a 89 mg de Fe2+/kg. Además, se determinó que 41 muestras de fideos que declaraban la fortificación de hierro en su lista de ingredientes, todas efectivamente contenían hierro, sin embargo, solo 7 se encontraron dentro del rango de fortificación referencial para la harina de trigo establecido en el reglamento ecuatoriano. La normativa específica para fideos está regida por INEN 1375, aunque actualmente no establece valores específicos de hierro.

Objective. To study the peculiarities of lifestyle and identify risk factors for disease development among students of a medical university. Material and methods. 320 second-year students of the Medical Faculty of the Siberian State University (78 males and 242 females) took part in the study. An anonymous online questionnaire with the use of Yandex Forms was conducted among the participants. Results. Girls had lower self-assessment of health. Among the respondents, 24.5% constantly take care of their health, 19.9% monitor their health only in case of illness, and 55.6% take care of their health periodically. Most students spend 2–3 hours (44.5% of girls and 61.4% of boys) or 4–5 hours (39.6% of girls and 30.0% of boys) to prepare for exercise. 30.9% of students do physical exercises and sports in their free time, 69.1% prefer other activities. 29.5% of surveyed boys and 27.0% of girls smoke. 49.3% of boys and 53.3% of girls use alcohol not more than once a month, 2–4 times a month - approximately equal number of respondents. More than half of the surveyed students noted that they do not use energy drinks. Among the respondents, 52.2% of girls and 49.3% of boys would like to get rid of bad habits, 26.1% of boys and 21.7% of girls do not see the need for this, the rest found it difficult to answer. Conclusion. Despite the fact that students have sufficient awareness of the components of a healthy lifestyle and express the desire to follow its principles, there are significant violations in the lifestyle of the study contingent. The obtained data confirm the need to develop comprehensive programs aimed at preserving the health of students, taking into account the identified characteristics of lifestyle and health risk factors.

Tingkat kehilangan pasca panen tanaman nanas dari tingkat petani hingga ke konsumen masih tinggi. Salah satu cara untuk mengurangi tingkat kehilangan tersebut adalah dengan teknik pengolahan pasca panen yang tepat. Penelitian ini bertujuan untuk mendeskripsikan dan menganalisis teknik pengolahan pasca panen nanas di pabrik JA Okinawa, Jepang. Metode yang digunakan adalah deskriptif kualitatif dengan memanfaatkan data primer, sekunder dan dokumentasi. Hasil pengamatan menunjukan bahwa nanas diolah oleh pabrik JA Okinawa dengan melalui tahapan proses pasca panen dan pengolahan. Proses pascapanen nanas terdiri dari pengumpulan buah dari petani dan grading. Buah nanas diolah menjadi produk primary processing, yaitu nanas kaleng dan secondary processing, yaitu selai nanas. Proses pengolahan terdiri dari pengupasan, pembersihan, pemotongan, sortasi, pengemasan, sterilisasi, pelabelan, penyimpanan dan distribusi. Pengolahan pasca panen nanas yang dilakukan JA Okinawa hampir sama dengan pengolahan nanas oleh perusahaan di Indonesia. JA Okinawa tidak melakukan proses pre-cooling atau pendinginan, berbeda dengan yang diterapkan oleh Inter-American Institute for Cooperation on Agriculture (IICA). Perbedaan tersebut disebabkan karena IICA menjual buah nanas dalam bentuk segar, sedangkan buah nanas di JA Okinawa diolah menjadi produk olahan seperti nanas kaleng dan selai nanas.

Published: November 2024

O objetivo desta pesquisa foi analisar a percepção dos acadêmicos do Curso de Ciências Contábeis da Universidade Estadual de Feira de Santana (UEFS) sobre a Contabilidade 4.0 e as inovações tecnológicos na área contábil, utilizando uma abordagem qualitativa de natureza descritiva e um questionário como instrumento de coleta de dados. A amostra foi composta por 35 concluintes. Os resultados revelaram uma predominância de acadêmicos jovens, indicando uma renovação geracional na profissão contábil. Foi possível constatar que eles compreendem a importância da contabilidade 4.0, de suas inovações tecnológicas e da necessidade de obtenção de conhecimentos sobre ferramentas como Robotic Process Automation (RPA), Blockchain, Inteligência Artifical (IA) e Business Intelligence (BI). Essa compreensão da importância de adquirir habilidades com essas tecnologias é essencial para que os futuros profissionais da área possam desempenhar suas tarefas de forma eficaz e dinâmica. Constatou-se também na revisão da literatura que o tema dessa pesquisa é pouco discutido nas Instituições de Ensino Superior (IES). Ademais, os concluintes julgam importante as novas tecnologias que surgiram com o advento da Contabilidade 4.0, porém, possuem pouca oferta institucional sobre o tema. Nesse contexto, consideraram de suma importância que as IES realizem ajustes na matriz curricular do curso, ofertando disciplinas que abordem o tema. Portanto, a contabilidade 4.0 traz oportunidades e desafios que precisam ser superados, e exigirá novas habilidades e competências distintas daquelas oferecidas pelas IES.
A conformidade dos limites legais mínimos das despesas em educação e saúde nos municípios catarinenses (2017-2022)

Published: November 2024

Este artigo verifica a conformidade dos municípios de Santa Catarina com os limites legais mínimos de despesas em educação e saúde no período de 2017 a 2022, com base nas análises das contas dos prefeitos realizadas pelo Tribunal de Contas do Estado (TCE/SC). Utilizando uma abordagem descritiva, o estudo verifica se os municípios catarinenses atenderam aos limites mínimos estabelecidos para despesas públicas em educação e saúde conforme a legislação nacional. A pesquisa detalha a alocação de recursos nessas áreas, que possuem mínimos de recursos financeiros definidos para garantir o acesso a serviços essenciais de qualidade. Os resultados indicam que, em geral, os municípios cumpriram os limites legais mínimos durante o período analisado. No entanto, a avaliação do TCE/SC mostrou-se limitada na análise da qualidade da aplicação dos recursos e seus impactos. Recomenda-se uma abordagem mais abrangente para aprimorar a gestão financeira e a eficácia dos serviços públicos, com foco na definição de padrões mínimos de desempenho e na eficácia dos gastos. Futuras pesquisas podem explorar a qualidade da aplicação dos recursos e o impacto das políticas, visando otimizar a gestão e promover sistemas de saúde e educação mais eficientes e resilientes.
Uma proposta de utilização do modelo discursivo de institucionalização aplicado à contabilidade gerencial
Authors: Reis Luciano Gomes dos
Published: November 2024

O presente artigo tem por objetivo efetuar uma análise dos estudos realizados sobre as relações existentes entre a área de Contabilidade Gerencial e o discurso organizacional, com uma proposta de utilização do modelo discursivo de institucionalização. A metodologia de pesquisa utilizada teve natureza exploratória, com caráter descritivo e ênfase no processo dialético. A existência de discursos implícitos ou explícitos em relatórios contábeis gerenciais ou financeiros pode afetar o modo pelo qual as realidades são construídas pelos indivíduos, sendo que a existência de diferentes discursos em uma organização pode afetar a institucionalização de novas rotinas. Considerando-se esta relação entre o discurso e o processo de institucionalização, o presente artigo teve como objetivo central analisar a evolução das pesquisas sobre o tema, com o objetivo de propor novas formas de abordagem nas pesquisas na área de contabilidade. Com base nessa análise, pode-se considerar em havendo influência do discurso no processo de mudança, dependendo da forma pela qual os conceitos que estão inseridos nos discursos de processos de mudança em contabilidade gerencial serão transformados em textos, utilizados na formação de regras, rotinas e hábitos, proporcionando a sua institucionalização (ou não), pode haver oportunidades de pesquisa para se avaliar como e porque esse processo ocorre, permitindo uma melhor compreensão do impacto do discurso na instituição de práticas contábeis. Especialmente em momentos nos quais discursos políticos antagônicos influenciam o ambiente organizacional, o discurso organizacional possui indícios de ampla influência na forma pela qual se formam as instituições, tendo como foco de análise a Contabilidade Gerencial.

A presente pesquisa teve como objetivo, identificar a percepção dos estudantes do curso de Ciências Contábeis da UNEB, Campus de Camaçari XIX e do Campus Fora de Sede localizado em Lauro de Freitas-BA, em relação a tributação de alimentos ultraprocessados e in natura proveniente da agricultura familiar. Para alcançar esse objetivo, empregou-se a aplicação de um questionário, visando analisar a perspectiva dos participantes sobre o tema em questão. A coleta de dados foi realizada por meio de um questionário, aplicado através do Google Forms®, formado por vinte questões adaptadas da Recomendação nº. 011 do Conselho Nacional de Saúde (CNS), resultando em um total de 63 respostas. Após análise, observou-se que a maioria dos estudantes concordam com o aumento dos impostos sobre os produtos ultraprocessados. Ademais, a maioria dos respondentes, demostraram apoio às questões relacionadas às medidas que favoreçam a tributação diferenciada, incentivem a produção de alimentos in natura provenientes da agricultura familiar, criação de estratégias fiscais capazes de influenciar nas escolhas alimentares da população e medidas para mitigar os impactos ambientais. Por fim, pesquisas futuras poderiam avaliar o papel da tributação como instrumento para estimular a produção e consumo de alimentos saudáveis, analisar a influência da tributação nas escolhas dos consumidores e investigar a percepção dos consumidores em relação à tributação de alimentos.
