Prof. Dr. César Ricardo Teixeira Tarley
Full Professor at the Department of Chemistry of the State University of Londrina, PR, Brazil
“From my point of view, Analytical Chemistry reaches its purpose when the development of analytical methods and/or use of analytical tools leaves the walls of universities and research centers and becomes technologies with practical applications.” read more
Letter
Expressing the Unit of Measurement in Analytical Chemistry
Maycon Lucas de Oliveira
Ph.D. candidate in Chemistry at the University of São Paulo, Brazil
Prof. Dr. Maria das Graças A. Korn
Full Professor at the Institute of Chemistry of the Federal University of Bahia, Brazil
Prof. Dr. Márcia A. M. S. da Veiga
Associate Professor in the Dept. of Chemistry at the Faculty of Philosophy, Sciences, and Letters of Ribeirão Preto, University of São Paulo, Brazil
“This Letter will focus on the mole and its derivative units, as they are central to expressing data and results in analytical chemistry. Historically, the mole was defined as the number of atoms in exactly 12 g of carbon-12. However, on May 20, 2019 (World Metrology Day), the GCWM redefined the mole as exactly 6.02214076 × 1023 elementary entities, as recommended by IUPAC. This alteration in the expression of quantities of matter enhances the precision and dependability of measurements.” read more
Point of View
Interaction between Industry and Academia: Is the Chemical Professional Master a Possibility?
Prof. Dr. Edenir Rodrigues Pereira-Filho
Full Professor in the Department of Chemistry at the Federal University of São Carlos, São Carlos, SP, Brazil
“Between 2017 and 2020, the Brazilian chemical graduate education system comprised a total of 74 graduate programs spread over several states. However, a mere five of these (just 6.7%) were exclusively dedicated to professionals already engaged in industry or teaching in public and/or private schools. This substantial underrepresentation reveals a significant imbalance within the system, suggesting that it is not fully aligned with the needs of the workforce and the educational sector.” read more
