Abstract

Zeolite is a hydrated aluminosilicate mineral (solid) in which silicate ions (SiO44-) and tetrahedral alumina (AlO45-) combine to form a porous/hollow and negatively charged crystal structure. Natural zeolite can be isolated from several sources, such as volcanic ash, sand, rocks, and rice husks, to industrial organic waste. Zeolite catalysts can be synthesized through various methods such as sol-gel, hydrothermal, ionothermal, and alkaline fusion. The purpose of modifying zeolite catalyst material is to improve its catalytic capabilities and physical and chemical properties, which can be done by various methods, including sol-gel, hydrothermal, ionothermal, and alkaline fusion. The use of zeolite-based catalysts and their derivatives has been widely used in various chemical reactions and industries such as isomerization processes, molecular cracking, to the manufacture of biodiesel. The conclusion is that zeolite is a widely developed material because of its abundant quantity in nature, and it is relatively cheaper and can be modified so that it can be used in various chemical reactions.

Abstract

Metabolomics has emerged as a critical field in understanding biological processes and disease mechanisms, necessitating advancements in analytical techniques to handle complex biological samples. This review explores the global landscape of metabolomics, with a focus on the use of spectroscopy and spectrometry. Techniques such as UV-Vis and Fourier Transform InfraRed (FTIR) spectroscopy offer fast and cost-effective metabolite tracing but are limited by their sensitivity, particularly for low-abundance metabolites. Nuclear Magnetic Resonance (NMR) spectroscopy, despite being less sensitive than mass spectrometry (MS), provides unparalleled structural information, distinguishing metabolites with similar mass-to-charge ratios. NMR's capability to detect metabolites in the 1-10 µM range highlights its effectiveness in metabolomics. This review categorizes advancements in these techniques, starting with global contributions to spectroscopy, followed by detailed discussions on FTIR strategies for metabolite tracing, and concluding with NMR's qualitative and quantitative applications in metabolomics and disease diagnostics. The review underscores the continuous development in sample preparation and data integration, enhancing the accuracy and applicability of these techniques, positioning NMR and FTIR as essential tools in modern metabolomic research.
