关键词： Upper-Division Undergraduate   Analytical Chemistry   Physical Chemistry   Computer-Based Learning   Fourier Transform Techniques  

摘要： This manuscript presents an exercise that utilizes mathematical software to explore Fourier transforms in the context of model quantum mechanical systems, thus providing a deeper mathematical understanding of relevant information often introduced and treated as a "black-box" in analytical chemistry courses. The exercise is given to undergraduate students in their third year during physical chemistry, thus providing a theoretical foundation for the subsequent introduction of such material in analytical instrumentation courses. With the reinforcement of familiar concepts such as the Heisenberg Uncertainty Principle, classical correspondence, and linear combinations in the context of both position and momentum space for a particle in a box, a better understanding of the mathematical implications of the Fourier transform is fostered. Subsequent analysis of a time-dependent function constructed via a linear combination and its transformation to the frequency domain provides a practical example relating to the Fourier processes applied in analytical spectroscopy. The final portion of the exercise returns to the position/momentum conjugate pair and explores how the construction of a narrow wavepacket via a sum of cosines illustrates the Uncertainty Principle once the probability density functions of each coordinate are analyzed. This exercise has been shown to not only reinforce fundamental concepts necessary for a true appreciation of quantum mechanics, but also help demystify the Fourier transform process for students taking analytical chemistry.

关键词： Natural deep eutectic solvents   Green analytical chemistry   Sample preparation   Detection enhancement   Green solvents  

摘要： Developing new green solvents is one of the key subjects in Green Chemistry. Ionic liquids and deep eutectic solvents were discovered as an option to replace organic solvents. However, ionic liquids and deep eutectic solvents (DES) have still some limitations to be applied to real chemical industry. In this sense, a new generation of designer solvents have emerged in the last decade as promising green media. When the compounds that constitute DES are primary metabolites, namely, aminoacids, organic acids, sugars, or choline derivatives, DES are called Natural Deep Eutectic Solvents (NADES). NADES fully represent green chemistry principles. These solvents offer many striking advantages including biodegradability, low toxicity, solute stabilization, sustainability, low costs and simple preparation. Thus, interesting applications in health-related areas can be proposed. This review presents an overview in order to up-to-date knowledge regarding NADES with special emphasis on their analytical applications and further perspectives as truly green solvents.

关键词： 3-Monochloropopane-1,2-diol   PROMETHEE   Multicriteria decision analysis   Green analytical chemistry   Analytical methods   Decision making processes  

摘要： In this study we perform ranking of analytical procedures for 3-monochloropropane-1,2-diol determination in soy sauces by PROMETHEE method. Multicriteria decision analysis was performed for three different scenarios - metrological, economic and environmental, by application of different weights to decision making criteria. All three scenarios indicate capillary electrophoresis-based procedure as the most preferable. Apart from that the details of ranking results differ for these three scenarios. The second run of rankings was done for scenarios that include metrological, economic and environmental criteria only, neglecting others. These results show that green analytical chemistry-based selection correlates with economic, while there is no correlation with metrological ones. This is an implication that green analytical chemistry can be brought into laboratories without analytical performance costs and it is even supported by economic reasons. (C) 2015 Elsevier B.V.

关键词： Food analysis   Omics   Analytical chemistry   Foodomics   Food biomarkers   Personalized diet  

摘要： The methodologies of food analysis have greatly evolved over the past 100 years, from basic assays based on solution chemistry to those relying on the modern instrumental platforms. Today, the development and optimization of integrated analytical approaches based on different techniques to study at molecular level the chemical composition of a food may allow to define a 'food fingerprint', valuable to assess nutritional value, safety and quality, authenticity and security of foods. This comprehensive strategy, defined foodomics, includes emerging work areas such as food chemistry, phytochemistry, advanced analytical techniques, biosensors and bioinformatics. Integrated approaches can help to elucidate some critical issues in food analysis, but also to face the new challenges of a globalized world: security, sustainability and food productions in response to environmental world-wide changes. They include the development of powerful analytical methods to ensure the origin and quality of food, as well as the discovery of biomarkers to identify potential food safety problems. In the area of nutrition, the future challenge is to identify, through specific biomarkers, individual peculiarities that allow early diagnosis and then a personalized prognosis and diet for patients with food-related disorders. Far from the aim of an exhaustive review of the abundant literature dedicated to the applications of omic sciences in food analysis, we will explore how classical approaches, such as those used in chemistry and biochemistry, have evolved to intersect with the new omits technologies to produce a progress in our understanding of the complexity of foods. Perhaps most importantly, a key objective of the review will be to explore the development of simple and robust methods for a fully applied use of omits data in food science. (C) 2015 Elsevier B.V.
