Food contaminants are substances that are not naturally present in food products and can migrate into food through various pathways. Mycotoxins, one of these, are chemical compounds produced by fungi such as Fusarium, Penicillium, and Aspergillus and can have carcinogenic effects on humans. Aflatoxin (AF) contamination, in particular, significantly impacts the economic value of crops. The...

Carbon and graphene quantum dots (CQDs and GQDs) are highly attractive for a wide range of applications due to their excellent characteristics, including high photoluminescence, tunable bandgap, water solubility, and biocompatibility. These nanomaterials exhibit strong quantum confinement and edge effects, which can be further modulated through surface functionalization with groups such as...

Nanomaterials based on WO3-x have emerged as highly promising materials due to their unique chemical and physical structures.

Pyrazoline is an important heterocyclic compound containing two adjacent nitrogen atoms and an endocyclic double bond. These derivatives possess a broad spectrum of biological activity, including antibacterial, anticancer, antitumor, anti-HIV, and anti-inflammatory activities. They generally exhibit blue fluorescence with high quantum yield in solution due to their intramolecular charge...

Vegetable oils are a fundamental energy source in human nutrition, as well as important components for the transport of fat-soluble vitamins and sensory quality. However, all vegetable oils, especially corn oil which is rich in polyunsaturated fatty acids, are quite susceptible to oxidation. Oxidation consists of chain radical reactions that lead to deterioration of taste, odor, and color, as...

Nanostructured materials provide high mechanical stability, high strength, and excellent thermal conductivity. However, preparing coherent nanostructures presents challenges. Furthermore, morphological properties vary depending on preparation techniques and experimental parameters.
