Abstract

This study analyzes the effect of temperature and composition on the FTIR spectroscopic properties of Barium Ferrite (BaFe) compounds, which have important applications in magnetic technology and data storage. The BaFe samples were synthesized with variations in cobalt (Co) and zinc (Zn) composition at different temperatures to examine changes in peak positions and intensities in the FTIR spectrum. The results show that the processing temperature affects the crystalline structure of BaFe, where increasing temperature leads to a decrease in the intensity of several major peaks, reflecting changes in metal-oxygen bonds and degradation of crystalline bonds. Meanwhile, variations in composition with the addition of Co and Zn increase the peak intensity in the FTIR spectrum, strengthening bond vibrations and improving material stability. This study provides important insights into how temperature and composition can influence FTIR properties in BaFe, which is relevant for applications such as permanent magnet production and magnetic data storage materials. These findings are expected to assist in the development of BaFe materials with more optimal magnetic and optical properties for various technological applications.

Abstract

The exploration of mathematical thinking styles is a vital area of investigation, particularly concerning its influence on science education within the classroom, given the significant role mathematics plays in advancing scientific understanding. The examination of this subject holds great interest, and its pertinence strongly bolsters prospective teaching and research endeavors. This research aims to perform a bibliometric scrutiny of mathematical thinking styles and their implication on science learning. The focus of this bibliometric inquiry is to elucidate and scrutinize literature congruent with the concept of mathematical thinking styles and their alignment with science learning. The SCOPUS repository is employed as the primary source of document references. Document selection and analysis were conducted using specific keywords in the 'document search' section. Employing diverse document screening methodologies pertinent to mathematical thinking styles and their implication on science learning, a corpus of relevant documents addressing the subject matter was identified. The sequential screening procedures and document findings are discussed comprehensively in this article. Fundamentally, articles pertinent to the bibliometric analysis theme, 'mathematical thinking styles and their implications for science learning,' underscore the significance of delving into students' mathematical thinking styles. Variances in these cognitive styles pose significant challenges for educators' pedagogical approaches in both mathematics and science instruction. This constitutes a pivotal implication of the present study, necessitating educators to adeptly navigate diverse mathematical thinking styles when structuring pedagogy in science and mathematics. Ultimately, this study stands as a pivotal reference for future investigations delving into themes associated with mathematical thinking styles.

Abstract

This study investigated the efficacy of Problem-Based Learning (PBL) in enhancing students' problem-solving abilities in physics education, addressing the lack of effective methodologies in nurturing this crucial skill. Utilizing a quasi-experimental design, 58 secondary school students from Nigeria were divided into an experimental group, which received PBL instruction, and a control group, which received traditional teaching methods. Over three months, both groups were assessed using an essay test format before and after the intervention, focusing on problem-solving abilities related to force and motion concepts. Descriptive and inferential statistical analyses were employed to evaluate the pretest, posttest, and n-gain scores, revealing significant improvements in problem-solving abilities within the experimental group compared to the control group. Specifically, students exposed to the PBL model exhibited higher average scores and greater improvement in problem-solving skills across various indicators, including understanding the problem, developing a plan, implementing the plan, and reflecting on solutions. The findings underscored the effectiveness of the PBL model in fostering active engagement, collaborative learning, and structured problem-solving processes, aligning with contemporary educational approaches that prioritize practical skill development and critical thinking. This study contributed to the growing body of literature supporting the efficacy of PBL in enhancing problem-solving abilities, highlighting its potential to cultivate a dynamic learning environment conducive to the development of essential skills in physics education.

Abstract

The objective of this article is to deliver a conceptual review of implications of heavy metals intake for brains and certain dietary nutrients such as copper, zinc, etc. Heavy metals are metallic or relative elements that are described bases on certain characteristics such as higher density, toxicity, and likes. They are present ideally in the natural environment, therefore, have to be expunged through human activities which are currently excessive in nature. Humans take in heavy metals because of excessiveness of human activities and thereby causing detrimental effects on the body, brain, development, and nutritional growth. On the brain, heavy metals improvised ways to circumvent the wall of the bilayer and exert harm on certain areas of the brain. This lead to poor functioning of the brain, as well as the body. Similarly, the heavy metals utilized efforts such as molecular mimicry or chelation to outcompete or impede the functions of essential micronutrients required for body functioning. Cd2+ impede Cu2+, Ca2+, and Zn2+; Pb2+ also has the ability to impede essential elements. Other heavy metals such as chromium, arsenic, exert similar approaches. This review elucidated the following themes: Meaning of heavy metals, dietary sources of heavy metals, non-dietary sources of heavy metals, dietary nutrients for learning/cognition, implications of heavy metals to the Brian or quasi, effects of heavy metals on micronutrients. Food materials, and water should be safeguarded from heavy metals through disparate methods. Curative methods for heavy metals removal (remediation) should be made accessible to all.
