Enantioselective Synthesis of Calix[4]arenes with Axial and Inherent Chiralities via Palladium/Chiral Norbornene Cooperative Catalysis
Authors: You Yiming , Cheng Hongwei , Huang Xiao , Wang Peng , Cong Hengjiang , Cheng Hong-Gang , Zhou Qianghui
Published: November 2024

Inherently chiral calix[4]arenes exhibit broad applications in asymmetric catalysis, chiral recognition, and materials science. However, their synthesis remains a significant challenge. Herein, we report a highly efficient method for the construction of calix[4]arenes with both axial and inherent chiralities through palladium/chiral norbornene (Pd/NBE*) cooperative catalysis. In this cascade reaction, the initial intro-duced axial chirality is dictated by Pd/NBE* cooperative catalysis, while the latter inherent chirality is controlled by the preestablished axial chirality via an unprecedented axial-to-inherent diastereoinduction process. This method employs ortho-calix[4]arene-tethered aryl iodides and β-substituted naphthyl bromides as starting materials, enabling the synthesis of a wide range of five- and six-membered benzo-fused calix[4]arenes with axial and inherent chiralities (30 examples) in one step with excellent enantioselectivities and diastereoselectivities. Preliminary studies of photophysical and chiroptical properties reveal that these axially and inherently chiral calix[4]arenes possess promis-ing glum values, demonstrating their potential in developing new organic optoelectronic materials.
Neoteric Solvents for Exploratory Catalysis: Hydrophosphination Catalysis with CHEM21 Solvents
Authors: Finfer Emma , Waterman Rory
Published: November 2024

The development of catalytic hydrophosphination has placed little emphasis on solvent effects, and most exploratory studies continue to be in toxic or environmentally harmful solvents. A comparative analysis of hydrophosphination catalysis using the three major categories of substrates, styrene, Michael acceptors, and unactivated alkenes, has been undertaken to assess a transition to green solvent alternatives. The compound selected, Cu(acac)2, has been identified as a highly active and perhaps most general precatalyst for hydrophosphination, which is enabled by photochemical conditions. Eight solvents were investigated from categories outlined in the CHEM21 guide, and seven were highly effective for most reactions. These results demonstrate a straightforward path to improving the sustainability of future studies in this and related catalytic reactions through bioavailable solvents, as well as highlighting potential pitfalls in reactions involving phosphine substrates.

Authors: DETHE DATTATRAYA , Singha Chirantan , Siddiqui Salman A.
Published: November 2024

Cucurbalsaminones, notable for their unique 5/6/3/6/5-fused pentacyclic triterpenoid structure, are potent inhibitors of P-glycoprotein. In this study, we propose a biosynthetic pathway starting from lanosterol, aiming to elucidate how these types of complex structures are synthesized by nature. Based on that, we present the first synthesis of cucurbalsaminone A in biomimetic fashion. This synthesis emphasizes key steps including oxidative olefin transposition, Lewis acid-mediated sequential migration of Me and H, and the oxa-di-π-methane rearrangement. This work provides valuable insights into synthesis of complex triterpenoid structures which have potential biological applications.
Hydrogenation of nitrile to primary amine with carbon-coated Ni/NiO@C catalyst under mild conditions
Authors: Liu Weidong , Liu Jianguo
Published: November 2024

Reusable catalysts based on non-noble metals with broad applicability used in nitrile catalytic hydrogenation synthesis are a key to a more sustainable production of primary amine. Herein, a simple and efficient carbon-coated non-noble metal nickel-based catalyst (Ni/NiO@C-600-200-1-H2O) was prepared for the hydrogenation of aromatic substituted nitrile to aromatic substituted amine under mild conditions (120 °C, 10 bar H2, 4 h). The carbon-coated catalyst has excellent anti-agglomeration ability due to its special carbon-coated metal structure, which can enhance the cyclic stability of the catalyst. Several aromatic substituted nitriles containing diffident functional groups such as halogen, methyl, methoxy, etc. are well tolerated in the Ni-based catalytic hydrogenation and can be converted to the corresponding amine with high activities (conversion rate over 99%, product selectivity reached 98.25%). Moreover, the catalyst can be easily recovered and reused due to its magnetic nature. In addition, we also applied the catalyst to the continuous flow reactor to catalyze benzylamine hydrogenation of benzonitrile under optimized conditions, the conversion rate and selectivity of the reaction were > 99%, and the continuous operation time was up to 31 h.

Published: November 2024

Conventional directed colloidal assembly enables fabricating complex hierarchical structures using external stimuli like electric fields, but lacks control over the assembly state in time. Chemical reaction networks have been discovered that transiently assemble colloids; however, they have slow dynamics (hrs – days) and poor temporal tunability, utilize complex reagents, and produce kinetically trapped states. Here we demonstrate transient colloidal crystals that autonomously form, breakup, and reconstitute in response to an electrochemical reaction network driven by a time invariant electrical stimulus. Aqueous mixtures of micron sized colloids and para-benzoquinone (BQ) were subject to superimposed oscillatory and steady electric potentials, i.e., multimode potentials, that induced electrokinetic flows around colloids and proton-coupled BQ redox reactions. We demonstrate wide tunability of transient assembly state lifetimes over nearly two orders of magnitude from 1 - 500 s by modifying the steady component of the multimode potential and electrode separation. Transient assembly states coincided with electrochemically generated pH spikes near the cathode. An electrochemical transport model showed that interaction of advancing acidic and alkaline pH fronts from anodic BQ oxidation and cathodic BQ reduction caused pH transients. We present theoretical and experimental evidence that indicates transient colloidal crystals were mediated by competition between opposing colloidal scale electrohydrodynamic and electroosmotic flows, the latter of which is pH dependent.
DiffractGPT: Atomic Structure Determination from X-ray Diffraction Patterns using Generative Pre-trained Transformer
Authors: Choudhary Kamal
Published: November 2024

Crystal structure determination from powder diffraction patterns is a complex challenge in materials science, often requiring extensive expertise and computational resources. This study introduces DiffractGPT, a generative pre-trained transformer model designed to predict atomic structures directly from X-ray diffraction (XRD) patterns. By capturing the intricate relationships between diffraction patterns and crystal structures, DiffractGPT enables fast and accurate inverse design. Trained on thousands of atomic structures and their simulated XRD patterns from the JARVIS-DFT dataset, we evaluate the model across three scenarios: (1) without chemical information, (2) with a list of elements, and (3) with an explicit chemical formula. The results demonstrate that incorporating chemical information significantly enhances prediction accuracy. Additionally, the training process is straightforward and fast, bridging gaps between computational, data science, and experimental communities. This work represents a significant advancement in automating crystal structure determination, offering a robust tool for data-driven materials discovery and design.

Breaking Barriers: The impact of gender equality on economic success : A comprehensive review
Authors: Samuel Asuamah Yeboah  , Diana Mogre
Published: November 2024

This systematic review explores the empirical evidence on the relationship between gender equality and economic performance in developing nations, focusing on the mechanisms through which gender equality influences economic outcomes. By conducting a comprehensive search of academic databases, we identified relevant studies published between 2000 and 2023. The findings consistently reveal a positive correlation between gender equality and economic indicators such as GDP growth, labour force participation, and productivity. Key mechanisms driving these outcomes include enhanced human capital, increased labour market participation, and improved decision-making and innovation. Despite generally robust quality assessments, some studies were limited by sample size and geographic coverage. This review highlights the significant economic benefits of promoting gender equality and emphasises the need for educational and legal reforms, as well as community initiatives, to overcome challenges like cultural resistance and policy implementation barriers. Policymakers and stakeholders are urged to prioritise gender equality to fully leverage its economic potential. Further research is needed to explore long-term and sector-specific effects.

Characterization of Silver Nanoparticles Prepared in the form of Powder and Their Application on Filters and Their Efficiency in Removing Bacteria Contaminating Drinking Water
Authors: Ali Khadhir Sabah , Habeeb Ammar A. , Abd Muhannad Mahdi
Published: November 2024

In order to ensure the availability of pure water free from contaminants, we focused on developing different laboratory-made filters and applying the ready-made nanosilver type Ag1 and the prepared type Ag2 prepared in the laboratory and loading them on the filters. We evaluated their effectiveness in removing and inhibiting bacteria based on the filter type and pore size, and we observed an increase in inhibition efficiency. In addition, we subjected the samples to UV testing within the wavelength range of 200-800, which is the range of nanosilver. We used EDX to confirm the presence of nanosilver in the samples. AFM examination, which shows the surface roughness values, pressure and grain size distribution of the prepared particles, and SEM examination, which shows the particle distribution, shapes and size measurement. To verify the stability of Nano silver and its strong negativity and confirm its size, a Zet test was performed to determine the negativity of the material and the nano size. The resulting water was analyzed with a TDS device to measure the dissolved salts in the water resulting from the different manufactured filters and to evaluate the drinking water and ensure that it is within acceptable levels. Then we used the Atomic Assay (AAS) to measure the percentage of nano silver in the drinking water resulting from the prepared filters and that the silver present does not affect the water because its percentage is very small and the silver loaded on the different filters has a moderate toxicity percentage that does not affect the water.

Authors: Hussein Jasim Mohamad , Khalel Jasim Saif , Abdullah Tariq Faraj , Jasim Awatif Saber
Published: November 2024

In this research, zinc nanoparticles were prepared using pulsed laser ablation in liquids. A pulsed Nd+:YAG laser with wavelength (532 nm) was applied to a pure zinc target immersed in deionized water, and the structural and optical properties of the prepared zinc nanoparticles were studied. The behavior of the UV absorption spectra of zinc nanoparticles was studied as a function of pulse number and ablation energy. The UV-vis absorption spectra showed absorption peaks in the ultraviolet region and in the visible region, the latter being responsible for the formation of zinc nanoparticles, and an increase in the intensity of the absorption peaks with increasing number of laser pulses was observed. Scanning electron microscopy results measured after examining drops of zinc nanoparticle solution showed that the nanoparticles were predominantly spherical in shape with nanoparticle sizes ranging from (42.49, 42.42, and 39.31 nm) respectively, and decreasing in size with increasing ablation pulses, with the best results at higher ablation pulses, the formation of zinc nanoparticles was confirmed by infrared spectroscopy, which confirmed the formation of nanoparticles.

Drawing on academic and practitioner literature and journal requirements, this article shows how a manuscript meeting those requirements could be structured, written and submitted to a journal to increase the chances of selection for review, revision and publication. The requirements of the New Zealand Journal of Health and Safety Practice, a newly established, practice-oriented journal, are used here to give specific examples of journal expectations.
The role of effective strategic leadership in transforming New Zealand's work health and safety system
Authors: Koia Henry
Published: November 2024

Hard working New Zealanders continue to die in New Zealand workplaces more than a decade after the Independent Taskforce on Workplace Health and Safety told us that all injuries and deaths in New Zealand workplaces are preventable. The single critical factor behind New Zealand’s poor workplace health and safety record is the gap in the provision of effective strategic leadership. Closing that fundamental gap will require the Minister who is for the time being responsible for the administration of the Health and Safety at Work Act 2015 to take accountability for the performance of the work health and safety system in meeting set harm prevention targets, and be answerable to the Prime Minister. To have any chance of upholding that accountability the Minister must lead effectively and strategically. To achieve that, the Minister’s strategic advisers must acquire many new insights generated from new thinking, theories, and models for aiding harm prevention such as the Chain of Interventions Model and the Risk Management Compliance Continuum Model.
Poster: A New Management Model for An Ancient Risk
Authors: Yu Lawrence
Published: November 2024

Most finely divided combustible materials are hazardous. When suspended in air and ignited, they can cause severe explosions. This phenomenon has been known for over 200 years. The first recorded dust explosion occurred on December 14, 1785, at a flower dust explosion in a warehouse in Turin, Italy. The entire industrial spectrum, including agricultural, chemical, metallurgical, mining, plastics, and woodworking industries, continues to be plagued by this problem.
Although the basic principles for controlling dust explosions have been understood for many years, knowledge is becoming increasingly sophisticated as incidents continue to occur.
The International Network of Safety and Health Practitioners Organisations framework requires health and safety practitioners to have some knowledge of explosions. This poster identifies some accessible sources of information that could be used by practitioners.
Motivation in Tertiary Performance Flute Study: How an Understanding of Theories of Motivation Can Enhance Performance Practice
Authors:   , Anderson Isabella
Published: November 2024

Research in the field of music education indicates a decrease in motivation is common as classical music students progress through the tertiary education system. While it can be assumed that students possess the intrinsic motivation to study music in the first place, this decline indicates that the culture of the conservatory system may not nurture it. This thesis explores ways that music performance students can use educational theories of motivation to improve their performance practice within the cultural context of tertiary study. The cultural system of the conservatory is examined, including the impact of conservatory values and the master-apprentice relationship with the instrument teacher on the student’s self-efficacy and intrinsic motivation. Self-determination theory is used to develop a recital-planning model that targets the needs of the student to enhance intrinsic motivation. The author conducted an autoethnographic study involving the performance of three recitals, using self-regulatory practices including goal-setting, strategies and tactics to monitor her progress. She found that approaching her goals in a mastery orientation with exploratory tactics led to greater integrated motivation. Additionally, repertoire that targeted the need for autonomy and relatedness, in this case contemporary repertoire by New Zealand composers, led to the most transformative experiences during performance and preparation. This study helped the author to find a sustainable and fulfilling way to engage with music learning.
Legal Regulation of Trading Activities Using Digital Formats
Authors:   Financial University,  Moscow, Russia, Eremin V.V.
Published: November 2024

The relevance of the article is due to the large-scale development of digital commerce, as well as the fact that the purchase and sale of goods and services is one of the locomotives of the economic development of any modern state. Nevertheless, digital trade can, under certain conditions, not only stimulate, but also slow down the economic development of both the country as a whole and its individual regions. The regulatory legal regulation of trade activities is designed to stop the negative consequences of the development of digital commerce and stimulate its positive impact on the domestic economy. Such incentives are especially relevant for achieving Russia's national development goals in the context of large-scale sanctions pressure. Increasing the effectiveness of this incentive is possible based on the analysis and implementation of relevant foreign experience in Russia. The subject of the study is the experience of regulatory legal regulation of trade using digital trading formats. The purpose of the work is to identify, based on the analysis of the legislation of six foreign countries, its features useful for implementation into Russian legislation. As a result of the research, a list of national features of foreign legislation regulating digital trade that are promising for implementation in Russia has been formed. The paper concludes that it is necessary to maintain a balance between limiting the market power of digital platforms and using their activities as a locomotive for the development of the national economy
The Possibilities of the State to Promote Farming and Rural Cooperation in Russia
Authors:   Financial University,  Moscow, Russia, Shchurina S.V.
Published: November 2024

The subjects of the study are farms and rural cooperatives as the basis for the economic development of rural areas. The purpose of the work is to determine the priorities of the state in the implementation of support for farms and rural cooperation in Russia. The article presents the results of state support for farms and rural cooperatives. The potential of the state program for financing infrastructure and the quality of rural life to ensure an increase in the commissioning of comfortable housing in rural areas and the construction and reconstruction of rural tourism facilities by 2030 has been assessed. It has been established that the full-fledged development of rural cooperation in Russia is hindered by contradictions in legislation, the high cost of credit resources associated with an increase in the debt of agricultural organizations to banks and credit cooperatives. The reasons for the lack of prestige of agricultural work among young people due to hard physical labor, low incomes and high cost of credit resources are determined. As a result, there is a lack of high hopes for the growth of the rural population by 2030. Conclusions are drawn about the need to continue state support for farming and rural cooperation in order to preserve the existing share of the rural population of Russia and implement the social mission of the cooperative movement.

Chasing butterflies? Experiences and challenges of being and becoming a TELL researcher against the digital applied linguistic context
Authors: Wu Junjie Gavin , Zhang Danyang
Published: November 2024

To burgeon in academia, early-career researchers face many challenges related to teaching, research, and career development. This paper seeks to explore these challenges through the lens of Bronfenbrenner’s (1979) ecological systems theory, highlighting the lived experiences of two TELL (Technology-enhanced language learning) researchers. By revisiting Bourdieu’s (1986) theory of capital, we analyzed how various forms of capital emerge from their experiences. We also referred to Davin and Norton’s (2015) model of investment for understanding TELL identities and investment. The findings reveal significant insights into the broader social issue of inequity, offering valuable perspectives on how these challenges can impact academic progression and success as a “TELLer.” Through this exploration, we aim to shed light on the systemic barriers early-career TELL researchers face and suggest pathways for addressing these inequalities within the TELL academic landscape.

Published: November 2024

La endogeneidad es un problema inevitable en modelos de elección discreta que causa estimación de parámetros inconsistentes. Dicha inconsistencia se puede ver reflejada en indicadores económicos que se utilizan para evaluar proyectos de transporte, como el valor subjetivo del tiempo y elasticidades. Por otro lado, se tiene evidencia del impacto que tiene la inclusión de variables psicosociales, tales como el hábito, la actitud y el afecto, en modelos de partición modal, cuya omisión podría causar endogeneidad. Estos antecedentes motivan estudiar la endogeneidad por omisión de variables psicosociales en modelos de partición modal.
Se proponen dos metodologías para evaluar endogeneidad, el Método de los Indicadores Múltiples (MIS) y el Método de Variables Latentes Integrado (ICLV). Para el primero, no se han encontrado aplicaciones con respecto a variables psicosociales. Más aún, se tienen muy pocos estudios que incluyen varias de estas variables de manera simultánea. Además, se proponen ambas metodologías interactuando multiplicativamente con el tiempo de viaje. Los datos provienen de encuestas realizadas a funcionarios, académicos y alumnos de la Universidad de Concepción y de la Universidad de la Frontera. Los modos estudiados corresponden al automóvil, la bicicleta y el bus.
Se demuestra que el afecto, la actitud y el hábito tienen un impacto significativo en la elección de modo de transporte, para todos los modelos estimados. Esto genera cambios sustanciales en los indicadores mencionados. Se tiene que el valor subjetivo del tiempo aumenta si se consideran las variables mencionadas aditivamente, pero disminuye si se consideran interactuando con el tiempo de viaje. Las elasticidades del tiempo de viaje se ven disminuidas para la bicicleta y para el automóvil al usar las metodologías propuestas, mientras que para el bus se ve aumentada. Por último, la elasticidad del costo también se ve disminuida para el automóvil y aumentada para el bus. Esto podría tener una repercusión directa en la evaluación de políticas públicas, dado que estas dependen de la partición modal, la cual podría estar sesgada.

En los centros galácticos activos (AGNs) podemos encontrar una diversidad de fenómenos físicos que emiten radiación electromagnética de formas muy distintas, las cuales son observables y diferenciales en distribuciones espectrales de energía (SEDs). Este trabajo se enfoca en modelar SEDs y estudiar sus formas, ocupando el código GRTRANS el cual utiliza una técnica de trazado de rayos para obtener intensidades mediante la ecuación de transferencia radiativa. En esta investigación se ocuparon los modelos esquemáticos HARM con un disco de acreción toroidal y rHARM3D con un disco de acreción semi-delgado. La radiación que se estudia es de sincrotrón térmica y no térmica variando componentes del AGN tales como la masa del agujero negro (M•), la razón de Eddington (λedd), la razón de temperaturas ion-electrón (Ti/Te), el exponente de la ley de potencia no térmica (P) y el ángulo de observación (α) que hay entre el observador y el eje perpendicular al plano del disco, con la finalidad de comprender como estos parámetros afectan la SED. También se estudian los mapas de luminosidad para cada uno de estas componentes a 22[GHz], 86[GHz], 230[GHz] y 345[GHz] para observar si existen dependencias en la frecuencia. Por último, se simula Sgr A* y se encuentra la distribución espectral de energía que mejor se ajuste a los datos. Esto se realizó encontrando la SED que tuviera una luminosidad bolométrica entre Lbol = (6,8−9,2)×1035[erg/s] para un estado quiesent” de Sgr A*. Como resultado encontramos que la razón de Eddington λedd = 1,5 × 10−9, la razón de temperatura ion-electrón Ti/Te = 3 y el índice de potencia P = 3,2 son los mejores valores para representar la SED de Sagitario A* considerando solo radiación de sincrotrón térmica y no térmica con un ángulo entre 20◦ y 40◦.

The study of geodiversity provides insight into the potential and limitations of an area's physical environment, making it highly valuable for public and private managers in supporting the development of appropriate land use and occupation proposals for a region. In this perspective, the Geodiversity Map of the coast of the state of Pernambuco was created by combining the Geodiversity Map of the Recife Metropolitan Region (RMR) and the Geodiversity Map of the Southern Coast of Pernambuco. Both were developed by the Geological Survey of Brazil through bibliographic studies and field surveys of geology, geomorphology, soils, and superficial formations, resulting in fifteen geological-environmental units composed of materials that significantly influence the suitability and usage constraints of the region. An example is the DCT unit, which covers a substantial area along the coastal zone of the northernmost municipalities of the RMR. Composed of sediments with varied composition (irregular alternation between layers of sandstone, siltstone, claystone, and gravel), it is widely used for urban occupation and mineral exploitation (borrow material in civil construction). However, on the slopes of the plateaus, particularly near the cliffs along the coastline, this area is unsuitable for housing due to the risk of landslides caused by slope gradients and the high susceptibility of these materials to erosion. Other information of significant importance and interest for public managers can be obtained as a result of this geodiversity study, such as mineral resources, groundwater potential and quality, geotechnical characterization, and areas prone to geological-geotechnical events that could impact land use, among others. All this knowledge is valuable for developing public policies and guiding actions by managers to generate employment and income, protect the environment, and promote health in the region.

Critical listening is a vital learning skill. Enhancing critical thinking skills through classroom activities is an important responsibility of teachers. Critical listening involves comprehending spoken information, evaluating it, and forming judgments and opinions based on what is heard. The current study was carried out at the Faculty of Education, Minia University, Egypt, to examine the effectiveness of a blended learning program utilizing genre analysis on enhancing critical listening skills among English majors. The current study used quasi-experimental research in an explanatory mixed methods design, with data collected across three phases. During the first phase, inventory was done with quantitative data aided by qualitative ones. During the second and third phases, sixty students of third-year English majors were randomly assigned to two groups: a treatment and a comparison one, containing 30 students each. The treatment group was trained in a blended learning program based on genre analysis, whereas the comparison group was taught the same content in a “Genre Analysis” course through the conventional method of teaching. The treatment group significantly outperformed the comparison group on the post-tests of the acquisition and use of critical listening skills. This research emphasizes the importance of the use of both blended learning programs and genre analysis in developing critical listening skills. Developing critical listening skills requires the learners to be skilful analysts as they need to analyze, judge, and evaluate what is said. The learner can have a better understanding and training on mastering these skills through practicing genre analysis. The improvement of listening comprehension affected the development of critical listening skills. The findings are discussed, and recommendations along with suggestions for further research are presented.
Written Ladakhi and the Future of Ladakh’s Culture

This study explores Written Ladakhi and the future of Ladakh’s culture in the newly formed Union Territory of Ladakh, India. The Ladakhi language is at a critical pivotal period. Its survival in the next two generations depends directly on the introduction of the Ladakhi language in its written form in the educational system. Using written Ladakhi for real communication is the key to survival. Spoken Ladakhi is still widely used in the home and in public, as well as at formal events, All India Radio Leh, television, and millions of audio and video recordings on social media and internet sites. However, because Ladakhi is not used in schools, the next generation is likely to find other languages more suitable for daily use, and the language is on the verge of extinction. Historically, no doubt, Ladakh and several other regions of the Indian Himalayas have shared a common literary heritage with Tibet. The Ladakhi language and culture have immense potential for development: it is shared by Buddhists, Muslims, Christians and others; the culture is valued by many non-local Indians and tourists; and it houses a major monument of world literature, the Kesar Epic. Therefore, an effort is being made in the present article to highlight the existing written corpus in Ladakhi and provide some information about the differences between literary varieties present in the region, and some language policy issues facing the Ladakhi language, its survival and potential development.
