What is the Best Definition for (Bio)Analytical Chemistry?
Prof. Dr. Ignacio Machado
Guest Editor of this Special Edition
Faculty of Chemistry, Universidad de la República, Montevideo, Uruguay
“…analytical chemists do not merely provide results; they also develop strategies to measure different chemical properties. Furthermore, they spend an enormous amount of time interpreting the obtained data. Thus, considering the vast variety of works involving analytical chemistry, a more comprehensive definition of the discipline is required.”
Professor Manuel Miró, a researcher with an extensive and prestigious academic career, kindly spoke to BrJAC
Prof. Dr. Manuel Miró
University of the Balearic Islands, Spain
“I do feel impressed by the quality of the research of many Brazilian analytical chemist groups working on cutting-edge technologies, such as point-of-care sensing devices, omics techniques, nanotechnology, and advanced instrumentation.”
How has the pandemic accelerated the transformation of Analytical Chemistry education from Generation Z to Alpha?
Prof. Dr. Mariela Pistón
Universidad de la República, Uruguay
“I would like to share my experience on how the pandemic irreversibly accelerated the use of digital tools, not to get closer to Generation Z, but without realizing it, reaching a transition to Generation Alpha (those born in the 2010s), despite the fact that they have not yet arrived at university.”
Metallomics as an essential analytical tool for the development of potential metallodrugs
Prof. Dr. Ignacio Machado
Universidad de la República, Uruguay
“Metallomics integrates research related to biometals, along with other disciplines such as genomics, proteomics, metabolomics, and bioinorganic chemistry. It is defined as the study of the metallome, the interactions and functional connections of metal ions or species with genes, proteins, metabolites, and other biomolecules in biological systems.”
Nutritional and Antioxidant Properties of South American Moringa stenopetala
Florencia Tissot, Maite Cuadrado, Jessica Santander, Julia Torres, Ignacio Machado
The nutritional value of South American Moringa stenopetala was assessed in this work, giving some deeper insight into the expected biological accessibility of the main nutrients present in raw leaves and prepared infusions. Metal ions were determined by FAAS; L-ascorbic acid, leucine, and tryptophan by LC-DAD; rutin, isoquercitrin and neochlorogenic acid by LC-ESI-MS/MS.
Development of a Green Methodology for the Determination of Artisanal Danbo Cheese Quality
Lucía Falchi, Mariela Pistón, Gabriela Casarotto, Silvana Carro, Cecilia Cajarville, Fiorella Iaquinta
A simple and fast method for the simultaneous determination of chloride and lactic acid in artisanal Danbo cheese was developed and validated. The proposed methodology combined a sample treatment using only ultrapure water as an extracting agent and ion chromatography with suppressed conductivity for the detection of the analytes.
Phosphate Interference in the Determination of Total Arsenic in Potatoes / Development of a Novel
Method for Surveillance Analysis
Ramiro Pérez Zambra, Alexandra Sixto, Mariela Pistón, Alicia Mollo
An alternative methodology for determining arsenic in potatoes using hydride generation microwave induced plasma optical emission spectrometry was developed. Limit of detection was 0.0030 mg kg-1 in fresh potatoes. The developed method is a robust, simple and low-cost alternative for total arsenic safe monitoring of this highly consumed worldwide vegetable.
Evaluation of the Effect of Silylation in the Development of an Analytical Method for the
Determination of UV Filters and Hormones by GC-MS
Jean Paulo da Rosa Coll, Michele Espinosa da Cunha, Maria Alice da Silva Amaral, Maurício Campesato Padilha, Gabriel Milton Gonçalves da Silva, Daniel Ricardo Arsand, Pedro José Sanches Filho
The objective of this work was to optimize a chromatographic method, combining derivatization (silylation) with MSTFA and analysis by GC-MS, for the determination of hormones and UV filters selectively, evaluating the effect of derivatization on the chromatographic response. The method developed for the qualitative analysis (SCAN mode) allowed the identification of the analytes more accurately, with similarities of the spectra superior to 80%.
Evaluations of Sisal Fiber as Biosorbent for online Preconcentration and Determination of Cu and Mn
coupled to MP AES using the Analytical Greenness Metric Approach
Javier Silva, Mariela Pistón
Evaluation of the Adsorbent Potential of Biochar obtained by Pyrolysis to remove Emerging
Maria Alice F. S. Amaral, Mirian D. Fusinato, Michele E. da Cunha, Jean Paulo R. Coll, João Henrique G. L. Lacerda, Pedro José Sanches Filho
BrJAC promoted a Panel Session to Celebrate the achievement of Journal Impact Factor2022 of 0.7
On Sept. 27, 2023, BrJAC held a panel session with conferences by Dr. Arruda, BrJAC's editor-in-chief, Dr. Kubota the BrJAC's first editor-in-chief, Dr. Boniek Vaz, the 2023 "Young Talent in Analytical Chemistry" award winner, and Déborah Dias (Clarivate). At the end, there was a round table on “Open Access Scientific Journals” by Dr. Arruda, Dr. Carrilho, Dr. Hantao and Dr. Kubota.
7th Uruguayan Congress of Analytical Chemistry (CUQA 7)
The 7th CUQA had approximately 200 participants from all around the country, as well as 40 foreign participants from Argentina, Brazil, Chile, and Perú. In this edition, 9 sessions with 7 lectures, 18 oral presentations, 110 poster presentations, and several social integration activities were held.
The 46th Annual Meeting of the Brazilian Chemical Society had “Chemistry: Linking Sciences and Neutralizing Inequalities” as its Theme
This meeting took place after the COVID-19 pandemic had cooled down, so this event was very large because the chemical community answered the call for registration. Many sponsors were also present and were very enthusiastic about the large number of visitors to their stands.
The 3rd Workshop on Inorganic Mass Spectrometry
The event had nine speakers from six international universities, 21 national speakers from nine Brazilian universities, one research institute and four private companies. Prof. Amauri Menegário, coordinator of the event, gave a brief interview to BrJAC.
