Synthesis and Characterization of Silicon Nanoparticles from Coal Fly Ash Using Ultrasonication as a Battery Anode
Authors: Robiansyah  , Bow Yohandri , Dewi Tresna
Published: October 2024

Fly ash, a byproduct of coal combustion, is rich in silica, alumina, and other minerals, making it a valuable resource for extracting high-purity silicon. The synthesis of silicon nanoparticles from coal fly ash involves several critical steps, including the extraction of silica (SiO2) via the sol-gel method, reduction of silica to silicon using the metallothermic method, and subsequent ultrasonication to achieve nanoscale particles. Studies have shown that fly ash can contain up to 49.21% silica, which can be further purified to 93.52% via chemical extraction methods such as acid leaching and alkali dissolution. The reduction of silica to silicon is carried out using the metallothermic method, which involves the use of magnesium-reducing agents to convert SiO2 to elemental silicon. This process produces silicon with a purity of about 61.3%, which can be further increased through ultrasonication. Ultrasonication is a technique that uses high-frequency sound waves to break particles into smaller sizes, resulting in more uniform and homogeneous nanoparticles. In this study, ultrasonication for 60 and 120 min reduced the average particle size of silicon from 208.94 nm to 58.87 nm and 20.13 nm, respectively, and increased the silicon content to 74.6% and 72.7%. X-ray diffraction (XRD) and distribution particle analyses confirmed the particle size reduction and homogeneity of silicon nanoparticles, indicating the effectiveness of ultrasonication in producing high-quality silicon nanoparticles. The synthesized silicon nanoparticles have significant potential applications, particularly as anode materials in lithium-ion batteries, due to their increased surface area and improved electrochemical properties. Furthermore, the use of fly ash as a raw material for the synthesis of silicon nanoparticles not only provides a cost-effective and environmentally friendly alternative to traditional silica sources but also helps in reducing the environmental impact of fly ash disposal. The integration of the methods and findings of this study underscores the feasibility and benefits of using coal fly ash for the sustainable production of silicon nanoparticles, which can be utilized in energy storage as anode materials in lithium-ion batteries.

La tesi centrale di questo libro è che la ricerca di una “forma logica” adatta alle esigenze dell’ontologia sia un’operazione di libera costruzione piuttosto che di scoperta. L’idea è che noi non sveliamo semplicemente la struttura profonda ma modelliamo la forma espressiva che meglio rende le nostre intuizioni metafisiche. Partendo da questa premessa, il volume propone quattro diversi momenti di messa a tema della possibilità e del metodo dell’ontologia, che condividono la medesima strategia metaontologica, pur nella molteplicità di riferimenti ad autori e stili filosofici. La strategia consiste nella valorizzazione del contributo delle strutture categoriali e nell’idea per cui il metodo per costruire un’ontologia è essenzialmente la creazione di una nuova formulazione ideale del linguaggio ai fini dell'indagine filosofica. Si scopre così che l’ontologia, invece di essere superata mediante analisi logica del linguaggio, trova nell’analisi logica del linguaggio la sua stessa possibilità.

The Anomalous Behavior of Stock Prices on the Canadian Securities Exchange
Authors: A. K. Cox Raymond , Cheng Quan , R. A. Cox Garrett
Published: October 2024

This paper examines the conformity of the distribution of stock prices on the Canadian Securities Exchange (CSE) to that theorized by Benford’s Law (BL). BL follows a logarithm law such that the leading digits have a higher probability of lower numbers such as 1, 2, or 3 versus higher numbers like 7, 8, or 9. This analysis can be used to detect fraudulent manipulation of stock prices. Previous research has applied BL to a broad range of data such as cost data, atomic weights, river areas, and populations, as well as stock prices. After collecting stock prices on the CSE, the number count for each digit was compared to the expected number given the frequencies posited by BL. A chi-square test was employed to determine statistical significance. The first digit was found to adhere to BL; however, the second digit was not congruent with that predicted by BL. There is an indication of possible manipulation on this stock exchange. These mixed results are consistent with the empirical evidence of other researchers. This evidence is relevant to auditors, shareholders, financial analysts, investment managers, government, and the CSE.

Nowadays, in many developing countries like India they are facing the shortage of energy. The Refrigeration system has become the major consumer of energy for many industrial as well as household applications. So, it is the need to enhance the energy efficiency of the refrigeration systems. Performance of the refrigeration system can be improved either by increasing the rate of heat absorption in evaporator or by reducing the compressor power. Use of efficient lubricant oil can help to remove the heat generated in the compression process which leads to less power consumption. Development in Nanotechnology makes it possible to develop a new class of lubricant called nanolubricant, in which nanoparticles are added in base lubricant oil to enhance the thermal properties. The two step technique with ultrasonic agitation force is used tosynthesise stable nanolubricant. The present study investigates the performance of an R-134a refrigerant vapour compression refrigeration system using nanolubricant with different volume concentrations (0.05%, 0.075%, 0.1% and 0.2%) of Graphene/Aluminium nanoparticles to mineral oil (MO) experimentally. The result shows maximum enhancement in COP approximately as 85% for 0.075 % volume fraction Nano lubricant as compared to base fluid. Use of nanolubricant saves approximately 27% compressor power.

In Domestic field & Professional life situations like that where a home maker or Professional may need to use potato slicer to make potato chips. Usually, regular potato slicer is used by small and medium range hot potato chips maker, but it consumes both time and energy of the chips maker because of its single blade. By introducing multi-blade in potato slicer, we can save the energy and time of the chips maker. Potato slicer with multi blade will not only save the energy and time of the chips maker, it also increase the production rate of the potato chips. For example slicer with three blades will increase the 3 times production of the regular slicer.

Water governance and agricultural livelihoods: Navigating human-ecological systems and farmer strategies in Rural Zimbabwe
Authors: Mugambiwa Shingirai
Published: October 2024

Water plays an important role in agricultural livelihoods and it is increasingly significant in regions where precipitation is low and variability is high such as in semi-arid and arid regions. In such regions, there is a pressing need to manage, allocate, and utilize water resources wisely in order to enhance the sustainability of communities. This study aims to assess how water governance systems relate to farmers’ practices and rural livelihood in rural Zimbabwe with emphasis on Mutoko District, Mashonaland East. This was a qualitative exploratory study. Data was collected through semi-structured interviews, focus group discussions, and participant observations. The study consisted of a wide range of stakeholders including smallholder farmers, local authorities, and water management bodies. The study found that water resources management in rural Zimbabwe is a combination of both formal and informal processes. The study also revealed that effective implementation of policies has been deterred by lack of funding and political interference. It has also been established that to combat water shortage in the region, local farmers have engaged in growing drought-resistant varieties of crops, use of traditional water harvesting methods, and creating water conservation management associations. The paper concludes that there is a need to consider the human-ecological aspects, especially the influence of agriculture on the livelihoods of communities.

The research was implemented in Al-Hamdaniya District, one of the districts of Nineveh Governorate in northern Iraq, located southeast of Mosul. The soil texture of the field is Clay loam. In the present study, fuel consumption, vibration in the driver's seat, noise, and exhaust gas temperature were investigated during four types of fuel that include diesel without enhancers fuel, diesel with Power Max enhancers fuel, diesel with Bardahl enhancers fuel, and diesel with Max-Tane enhancers fuel, and two angles of penetration were 45◦ and 55◦. Two plowing depths of 35 and 45 cm were considered. The results indicated that fuel consumption and exhaust gas temperature recorded a significantly negative loss with diesel fuel without improved additives, reflecting the economic loss and the efficiency performance. The results showed the positive superiority of diesel fuel with improved additives in the fuel consumption, vibration in the driver's seat, noise, and exhaust gas temperature, except diesel with Max-Tane and diesel with Power Max enhancers achieved a negative effect increase in vibration in the driver's seat and noise, respectively. However, the values remained within the measurements approved by European Parliament Directive 2003/10/EC. Moreover, increasing the angle of penetration and plowing depths increases fuel consumption, vibration in the driver's seat, noise, and exhaust gas temperature. Finally, the results indicate the superiority of the fuel-improved additives and angle of penetration with plowing depths achieved the best results in the studied trait except for the vibration in the driver's seat at the intersection diesel with Max-Tane with a penetration angle of 55o and plowing depth of 45 cm.

Authors: Nabil Myvel
Published: October 2024

This study investigates the impact of political risk, represented by political index for each country, on the financial stability in Middle East and North Africa (MENA) region, which is divided into three groups according to the level of income during 2009-2021. Financial stability is measured by a Z-score and an aggregate banking stability index. This has been applied on 9 countries using panel data analysis. The findings reveal that political risk has a significant negative effect on financial stability partially, most notably on the Z-score side. Macroeconomic factors, including broad money, domestic credit to private sector by banks, GDP growth, income, and market capitalization of listed domestic companies, are also identified as determinants of financial stability. The study contributes to the literature by providing empirical evidence on the impact of political risk on financial stability in MENA region over 13 years. Practical implications for regulators, policymakers and investors are discussed, highlighting the need for a better understanding of political, economic and health risks and their effect on stock performance.
