Recent Progress in Developing High-Performance Anode Materials for Next-Generation Sodium-Ion Batteries
Authors: Ha Sion , Kim Kyeong-Ho
Published: April 2024

Rechargeable lithium-ion batteries (LIBs) have attracted great attention due to their large-scale energy storage applications such as electric vehicles (EVs) and grid-scale energy storage systems (ESSs). The ongoing transition towards EVs has accelerated ever-increasing demand for LIBs that causes the shortage of lithium metal resources and their expensive price. Therefore, great efforts have been made to exploit an alternative system that replaces the conventional LIBs. While sodium-ion batteries (SIBs) can be the most evident alternatives to LIBs based on the natural abundance and low cost of sodium resources, the major scientific challenges reside in developing the new anode materials due to the poor performance of conventional LIB anodes in Na cells, such as graphite and silicon. This article reviews the potential of SIBs as promising alternatives to LIBs and recent progress in developing high-performance anode materials for SIBs. The strengths and drawbacks of recently developed anode materials have been discussed, including graphite, hard carbon, silicon, phosphorus, and other transition metal compounds such as oxides, phosphides, and sulfides.

The research revealed innovative approaches to the development of Podillia pottery centers. Podillia is considered as a historical and ethnographic region, which is considered one of the most developed centers of pottery production in Ukraine. It is characterized that, over the centuries, a characteristic plasticity of products, a high culture of composition, local systems of ornamental motifs and their semantics, coloristic solutions, which are ensured by the use of local colored clays, have been formed in Podillia. A set of measures and tools for the promotion of ceramics Podillia, which allow the community to effectively distribute information about itself, its activities and needs at different levels of perception and among consumers of this information, is considered. A number of projects aimed at the integration of Ukraine into the European space have been characterized, in particular, the project "Revival of the traditions of Bar ceramics V.2.0", the virtual 3D museum of Bar ceramics, the ceramic workshop "Yivga", "Lytinska ceramics", "KeramMisto", the space "Ethno Chary". The work of Podillia potters - Mykhailo Didenko, Yulia Gushul, Viktoria Nikolayeva, Serhiy and Svitlana Pogontsiv and others - is characterized. It has been proven that none of the regions of Ukraine is characterized by such a wealth of varieties of ceramics as Podillia, which is determined by natural-geographical, economic and cultural-historical factors, in particular, the region has huge deposits of various pottery clays. It has been proven that modern potters of Podillia, reviving the folk traditions of their region, are working to preserve Ukrainian spirituality and identity in the conditions of martial law in order to preserve the cultural heritage of Ukraine in the world cultural space. Initiatives in the field of creativity and culture can contribute to the development of local communities and improve the quality of life.

Modern information communication networks include monitoring subsystems. The operation of monitoring subsystems is based on the operation of various sensors. Among the sensors used in the monitoring subsystems, thermoelectric sensors occupy an insignificant share. In order for thermoelectric sensors to become more widespread, it is necessary to solve the problem of a small value of thermoelectric efficiency. It is proposed to solve this problem by switching to sensors based on anisotropic bipolar thermoelement.
In the presented work, the influence of thermoelectric vortices with turbulent flow on the sensitivity of sensors based on anisotropic bipolar thermoelements was studied. The dependence of the value of the transverse thermal-EMF  of this structure on the anisotropy coefficient K of the anisotropic bipolar thermoelectric material was determined. Corresponding singular points and limits of their existence are revealed. The dependence of the directions of rotation of vortices with a turbulent nature of the flow on the direction of approach to these points was established. The temperature sensitivity of the sensor based on an anisotropic bipolar thermoelement made of single crystals of cadmium antimonide with both unipolar and bipolar characteristics was evaluated. Research results show a significant increase in the temperature sensitivity of such sensors based on anisotropic bipolar thermoelements, which can be used as thermal sensors for monitoring individual elements of the information communication system. Such thermoelements will have an improved coefficient of temperature dependence of volt-watt sensitivity compared to anisotropic unipolar thermoelements. The conducted numerical calculations show the prospects of using anisotropic bipolar thermoelements as sensors for monitoring modern information and communication systems for collecting information, both about the system itself and the environment.

Development of software system for monitoring and forecasting of vehicle traffic is considered in the paper. Possible ways of data structures and storages organization for such a system were analysed. Implementation features of these data structures for Python programming language were considered based on the NumPy, Pandas packages. Special attention was paid to the application of lists, multidimensional arrays and dictionaries as data structures and files of different types as data storages. Web application was developed based on the Django web development framework. The corresponding database structure was proposed and presented for data storage organization. The developed web application supported calculation of time necessary for realization of different scenarios. These scenarios define implementation of data structures based on the corresponding algorithms in software system. Data storages were filled with observation data, accumulated in Madrid through the period from 1.01.2019 to 30.09.2022. 59 stations were used to measure vehicle traffic. Base monitoring scenarios include data reading and selection. Vehicle traffic forecasting is done under resource constraints. Data is prepared in the form of time series, as well as in the form necessary for selection of informative stations. Search speed acceleration was provided through the creation of indexes. Recommendations were given for design decision making concerning choice of data structures for support of different variants of software system application. Data, previously structured as lists and dictionaries, makes an effective foundation for data selection and preparation. If data has to be read from a file at the beginning of a corresponding operation, then software communication with database is a more appropriate approach.

In today's digital world, there is an active use of databases, and the relevance of protecting them is growing every day. After all, databases can contain a wide range of confidential information (personal, financial, government, commercial, etc.), unauthorized access to which will lead to irreversible negative consequences, including material damage, reputational losses, and even legal problems. In addition, the number and complexity of cyberattacks is growing every day. Attackers use various methods to gain unauthorized access to databases, such as the use of software vulnerabilities, social engineering methods, brute force attacks, etc. Therefore, the problem of increasing the security of databases against unauthorized modification is of great importance. In this regard, this paper proposes to address this issue by using blockchain technology in combination with the Proof-Of-Work consensus algorithm, which ensures the security and integrity of the system, and helps prevent fraud and abuse by using cryptographic methods to protect the blockchain from unauthorized access and modification. It is also worth noting that the Proof-of-Work algorithm has a number of other advantages, such as decentralization, transparency, and data immutability after it is added. Thus, to achieve the goal, the subject area was analyzed, the known methods on which the operation of database security systems is based were investigated, the architecture and algorithm of the security module were created, which allows for decentralized data storage and, accordingly, increases the level of their security by using a special consensus protocol to coordinate the contents of the registry, as well as cryptographic hashing algorithms and electronic digital signatures to ensure the integrity of the parameter transfer transaction.

Використання традиційних автоматизованих систем і промислових роботів зазвичай обмежується добре структурованим середовищем. Цим системам часто не вистачає здатності ефективно справлятися зі складністю та невизначеністю, що призводить до обмеженої адаптивності. Як наслідок, їх застосування на малих і середніх підприємствах обмежене. Автоматизована система моніторингу параметрів міжсистемних з’єднань на основі адаптивних алгоритмів є інноваційним підходом, спрямованим на підвищення продуктивності виробництва та надійності кабельно-провідникової продукції. В рамках даної роботи проведено аналіз існуючих методів контролю параметрів міжблочних електричних з’єднань, що дозволило виявити їх особливості та недоліки. Цей аналіз підкреслив необхідність розробки нових підходів до керування цими параметрами за допомогою адаптивних алгоритмів.
У контексті даної проблеми використання адаптивних алгоритмів забезпечує системі можливість мінімізації частоти помилок відтворення сигналу. Це сприяє підвищенню точності та надійності процесу контролю, оскільки система здатна реагувати на непередбачені ситуації та коригувати свою роботу в режимі реального часу. Крім того, ключовим елементом даної роботи є розробка структурної схеми системи управління модульного типу. Така схема забезпечує гнучкість і масштабованість рішення, оскільки кожен модуль системи відповідає за окремий аспект контролю параметрів міжсистемних з’єднань. Такий підхід спрощує управління та обслуговування системи, а також робить її більш доступною для впровадження в різноманітних галузях.
Результати дослідження свідчать про актуальність проблеми керування параметрами міжблочних електричних зв’язків та підтверджують перспективність використання автоматизованої системи керування з адаптивними алгоритмами.

Flax belongs to the few industrial crops, from which two types of products can be obtained simultaneously - seeds and fiber. Industrial processing of straw aimed at obtaining fiber can solve issues related to providing enterprises with domestic natural raw materials. The wide range of use of fibers from linseed stalks has contributed to a number of studies on the processing of linseed stalks. However, linseed oil straw has some disadvantages that limit its use and the development of new technologies for the primary processing of flax fiber. In order to obtain more profit from flax straw, producers need to know the quality of the straw, so the factors that affect its suitability for processing and processing methods that will increase the value for processors and producers need to be researched. The factors that affect the suitability of flax straw for processing are established: trash, weeds, plant height, fiber content, straw length and orientation, and transportation cost.
It has been proven that it is necessary to choose varieties of linseed with a high fiber content and to focus on varieties with high stems and during mowing to use methods that will increase the height of flax straw in order to avoid the loss of the harvest of the technical part of the stem; increase sowing rates to increase fiber yield; control the density of crops and the height of the plant to manage the ratio of seeds and straw in accordance with production tasks; check crops for clogging and the presence of weeds. It is advisable to use devices to quickly obtain data on the fiber content in order to determine the suitability of straw for processing, so it is promising to conduct further research in this direction.

Today, laser cutting is widely used in the automotive, shipbuilding and other industries where aluminium, low-alloy and stainless steel are cut. The choice of a laser system for a cutting process is heavily influenced by criteria such as achieving high cutting speeds and maximising production productivity, which can help to achieve high quality cuts and eliminate the need for rework. Increasing the efficiency of the laser cutting process, as well as its flexibility and quality, can reduce production costs.
Machining stainless steel is associated with a number of difficulties, which, in turn, are caused by the material's properties. That is why laser cutting is one of the most effective methods of processing stainless steel. The quality of manufactured parts is inextricably linked to cutting modes.
The paper envisages the optimisation of stainless steel laser cutting modes using the Taguchi method. Such parameters of the cut as roughness, heat affected zone, and geometric shape deviation were studied. The studies were carried out on a Smart 3015 laser cutting machine. The control variables of laser cutting according to the Taguchi method and their influence on the response variables were determined.
According to the results of the studies, it was found that the smallest deviations in geometric shape, thermal impact zone, and surface roughness are achieved at a laser speed of 40 cm/min, laser power of 1000 W, frequency of 50 Hz, and gas pressure of 0.5 MPa. In addition, the percentage effect of each cutting parameter on the response variables was determined. A study using the Taguchi method showed that 80-90% of the influence is exerted by the laser power.

A Mathematical Contradiction in the Special Theory of Relativity
Authors: Haraux Alain
Published: April 2024

In this study, we critically examine one of the foundational postulates of the special theory of relativity – the invariance of light’s velocity across different frames of reference. Through a straightforward, one-dimensional analysis inspired by historical astronomical observations, we uncover a mathematical inconsistency arising from the simultaneous application of light-speed invariance, relativistic time contraction, and space contraction as posited by Einstein’s theory. This contradiction, highlighted by examining the collision between a photon and a moving object, invites a reevaluation of the underlying principles of special relativity. By elucidating this inconsistency, our work challenges the orthodoxy of relativistic velocity composition, suggesting a return to classical mechanics’ simpler vector addition rule might be necessary. This research not only contributes to the ongoing dialogue questioning the absolute nature of light speed but also underscores the potential need for a paradigm shift in our understanding of physics, with profound implications for future theoretical and experimental inquiries.

ARCHDIOCESE OF JAKARTA: AN ANALYSIS OF ENTREPRENEURIAL PROACTIVENESS AND RISK TAKING
Authors: Wulandari Respati
Published: April 2024

The Archdiocese of Jakarta, Indonesia's oldest diocese with a dynamic megapolitan population, must be proactive and willing to take risks in order to meet the needs of Catholics and fulfill its mission to the general public. With 37 parishes and a diverse parishioner population, Catholic priests encounter a variety of problems in carrying out the church's mission. A proactive approach and the willingness to take risks can boost organizational success. There has been no previous research on the Roman Catholic church with the concept of entrepreneurship, hence this study fills a research gap in terms of entrepreneurship theory and context in religious organizations. Using the framework of entrepreneurial proactiveness and entrepreneurial risk taking, in-depth interviews with 19 parish priests revealed that 19 parish priests applied entrepreneurial concepts to their ministry work. This study adds to the academic side of entrepreneurship in the context of religious non-profit organizations and offers practical guidance to NPO managers who are in a similar scenario.

Seagrass meadows serve as vital blue carbon ecosystems, sequestering significant amounts of CO2 and playing a crucial role in climate change mitigation. Semujur Island, located in the Bangka Belitung Province, exemplifies numerous small Indonesian islands boasting extensive seagrass meadows lining their shores. This research seeks to (1) describe the community structure of seagrass on Semujur Island, (2) assess the carbon storage within the seagrass ecosystem, and (3) analyze the relationship between seagrass community structure and carbon reserves across three distinct sites. According to the results of this study, there are eight species of seagrass on Semujur Island, i.e., Cymodocea rotundata, Enhalus acoroides, Halodule uninervis, Halophila ovalis, Oceana serrulata, Syringodium isoetifolium, Thalassia hemprichii, and Thalassodendron ciliatum. Diversity indices varied among sites, ranging from 1.48 to 1.72. Species evenness indices varied between 0.83 and 0.92, while dominance indices varied between 0.20 and 0.28. The highest estimated carbon stock was obtained at the site dominated by the species H. uninervis (75.11 MgC/ha); followed by the site dominated by T. hemprichii (50.55 MgC/ha). The correlation between seagrass community structure, including density and coverage, and carbon stocks demonstrated a moderate positive correlation, with coefficients of 0.430 and 0.528, respectively (p<0.05). This research highlights the significance of integrating ecological dynamics into the management of seagrass ecosystems to enhance climate change mitigation efforts. Additionally, it offers valuable data as a reference for the restoration and conservation of seagrass ecosystems.
