    CHARACTERIZATION AND APPLICATION OF FERRITE MATERIAL
    (wolkite universty, 2024-09) FIRATOL AHIMED; FEREFEN TADESE; GABI HASSEN; GEMECHIS TAREKEGN
    The material characterization of ferrites includes the investigation of crystallography, structural morphology, chemistry (identification of chemical constituents, chemical composition, and their distribution), thermal properties, magnetic properties, and electrical properties. IN this study, the main focus of the present work is to review synthesize nano magnetic particles of different ferrite (AFe2O4, where A represent Zn, Co, and Mn). The ferrite nanoparticles were effectively prepared by sol-gel, hydrothermal and chemical co-precipitation technique. The XRD analysis affirmed the pure phase development of cubic spinel structure with nanometric crystallite measurements of the powder XRD analysis revealed the high purity and single phase of the zinc ferrite sample average crystallite sizes are 21 nm and 27 nm for the zinc samples annealed in air atmosphere at 300 °C and 600 °C.and the calculated crystallite size was found to be 14.33 nm for cobalt, 27 nm for zinc ferrite and the particle size was calculated as 23.53 nm for manganese ferrite. Finally, Cyclic volta metric analysis, Electron paramagnetic resonance (EPR) spectroscopy, Energy dispersive X ray analysis (EDAX) and liquidity coverage ratio (LCR), dielectric behavior ,frequency and proportion of highly liquid assets are not included in this study. Therefore, this will be considered in future studies to further enhance the understanding of the ferrite material.

    Temperature Depends on the Electrical Conductivity of Metals and Its Relevance to Industrial Applications
    (wolkite universty, 2024-09) Bereket Yohannes; Eyob Dejene; Tigist Enawagaw
    In many industrial applications, such as electronics, energy transfer, and materials processing, the electrical conductivity of metals is a fundamental and essential characteristic. Temperature has a substantial impact on the conductivity of metals, which is not always constant. In order to better understand the underlying physical principles and their implications for industrial applications, this study explores the temperature-dependent behavior of electrical conductivity in metals. The research reveals that the electrical conductivity of metals decreases with increasing temperature, with the rate of decrease varying significantly between different metals. It also examined the effects of temperature on the microstructure and defect dynamics of metals, which are critical in determining their electrical conductivity. The findings of this study have significant implications for the design and optimization of industrial processes, such as electrical wiring, heat treatment, and materials synthesis. Furthermore, our results highlight the importance of considering temperature-dependent conductivity in the development of advanced materials and technologies, including high-temperature electronics, energy storage devices, and electromagnetic shielding applications. Overall, this study provides new insights into the complex relationship between temperature and electrical conductivity in metals, with far-reaching implications for industrial innovation and technological advancement.

    Applications of Nuclear Decay Mechanisms in Technological Advancements and Future Prospects
    (wolkite universty, 2024-09) Akalu Shanka; Mahider Temesgen; Habitamu Bitew
    Radiation refers to the energy or particles from a source that travels through space or other mediums. For instance, light, heat, microwaves, and wireless communications all are its forms. So, through this article, we will be able to help you understand this in detail. We often categorize it into two types that depend on the energy of the radiated particles. The first is ionizing radiation. After that, we have non-ionizing Radiation, which comprises alpha particles, beta particles, and gamma particles. Between the research of this document, the committee has highlighted some of the ways that nuclear physics impacts our lives along with some of the individuals poised for leadership in nuclear physics. In this project, we provide a more detailed. Overview of some of the ways in which nuclear physics is being applied to address the nation’s challenges in health, homeland and national security, nuclear energy, and some of the innovations taking place in developing and exploiting new technologies arising from nuclear science. Rising expectations best characterize the current projections of nuclear power in a world that is confronted with a burgeoning demand for energy, higher energy prices, energy supply security concerns, and growing environmental pressures. Nuclear power is a cost-effective supply-side technology for mitigating climate change and can make a considerable contribution to climate protection. This paper reviews the current status of nuclear power and its fuel cycle and provides an outlook on where nuclear power in relation to climate change may be headed in the short-to-medium run, say 20 to 40 years from now

    COMPARISON OF SINGLE STAGE AND TWO STAGE CMOS OPERATIONAL AMPLIFIERS
    (wolkite universty, 2024-09) Addisu Mulu; Danait Solomon; Zelalem Getnet
    Operational amplifier (Op-amp) is versatile device that can be used to amplify DC as well as AC input signals. In this project work a two stage CMOS op amp and single stage CMOS op amp has been compared based on values of their performance parameters by using 0.35μm CMOS technology and the same power supply (3.5V). As the result shows that: single stage CMOS op amp has larger phase margin and smaller power dissipation than two stage CMOS op amp. This shows that single stage CMOS op amp is more stable and operates longer duration of time than two stage CMOS op amp with small energy loss. Whereas two stage op amps produces the output which is almost twice larger than single stage op amp. In addition the noise in the output of two stage op amp is less than single stage op amp. So to obtain high output it is better to use two stage op amps than single stage op amp. By results and reasons suitable choices of CMOS op amp will be done based on their performance parameters.
