This master’s dissertation addresses the development, analytical performance characteristics, and application of analytical methods for the determination of trace metals in urban dust samples, with a focus on the environmental ...

In a contemporary world marked by environmental imbalance, the Energy Transition arises as a solution to mitigate the emission of pollutants from fossil fuels burning. Following this scenario, a promising alternative is, ...

Dry reforming of methane enables the production of synthesis gas (syngas) with an H₂:CO ratio of approximately 1:1 from CH₄ and CO₂, both greenhouse gases, using nickel-based catalysts. In this work, a perovskite route was ...

Natural products, especially medicinal plants, represent a significant source of bioactive compounds with considerable potential for the development of new synthetic substances due to their rich diversity of ...

Flours obtained from oilseeds (almond, peanut, coconut, and flaxseed) are widely consumed due to their functional properties and potential health benefits, including being a source of inorganic constituents such as Cu, ...

The 3-acylthioenaminones are characterized by an N-C=C-C=S a-acylated conjugate system which makes this species an interesting starting material for obtaining various derivatives, such as nitrogen heterocycles. These ...

The development of reference materials is essential to ensure the quality and comparability of analytical results. This dissertation presents the study of a candidate soil reference material for inorganic analysis, ...

The apple (Malus domestica) is a fruit from the Rosaceae family, known for its medicinal properties present in the pulp, seeds and peel. Apple extracts have various biological activities, including antioxidant, anticancer ...

Portable, low-cost colorimetric sensors are emerging as practical tools for field environmental monitoring. In this study, two colorimetric analytical devices based on bacterial nanocellulose (BNC) and electrospun polymeric ...

Microemulsions are thermodynamically stable and macroscopically homogeneous systems composed of water, oil, surfactant, and co-surfactant. Usually, these surfactants are synthesized from petroleum derivatives and, therefore, ...
